Answer:
This question is incomplete as it lacks statements, the statements and the answers are as follows:
occurs in organisms that sexually reproduce - MEIOSIS
occurs during growth and development - MITOSIS
the DNA is replicated - MITOSIS AND MEIOSIS
occurs in all organisms - MITOSIS
the number of chromosomes remains the same - MITOSIS
the number of chromosomes reduces by half - MEIOSIS
Explanation:
Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.
The following are characteristics of the two division processes based on this question:
MITOSIS:
- It occurs during growth and development of an organism.
- it involves DNA replication
- it occurs in all organisms since every living organism undergoes growth and development.
- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n
MEIOSIS:
- It occurs only in organisms that sexually reproduce.
- it also involves the replication of DNA
- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.
Anyone know the answer?
Answer:
the answer c. is correct
Explanation:
During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.
Darwin’s finches evolved on an island. What is the main reason that islands often provide good examples of evolution?
Answer:
They allow for automatic biogeographic isolation. In rock layers, jellyfish fossils are found lower than trilobite fossils, and trilobite fossils are found lower than ammonite fossils.

Part C: Take Notes In a separate location, take notes from the sources you have identified. The notes will provide details for your presentation. While taking notes from texts and websites, use these reading strategies. In the space provided, write four pieces of information that you intend to use in your presentation. im to lazy to write the notes
Answer:
I do that sometimes I take notes in a separate location so is this like for your math homework cuz I am good enough but I don't like it that much but I'm good at it and sources identify things that will the source is like a key a key like you can open and close the door with and you're opening the key with the source so it really really really really and wouldn't be a good thing to take notes wherever you go like if you were writing a book you would want the source and the emotion and everything you wanted to buy

Increasing __________ is one of the most effective treatments for bowel and bladder problems.
The bacterium Methylophilus methylotrophus can use methanol and ammonia for protein synthesis. The glutamate dehydrogenase gene from E. coli was introduced into M. methylotrophus using recombinant DNA techniques. Under high ammonia conditions, the introduction of the glutamate dehydrogenase gene into M. methylotrophus resulted in an increase in protein yield. Select the statements that are reasonable explanations for the increased protein yield in the modified M. methylotrophus. Glutamate dehydrogenase catalyzes the formation of glutamate and glutamine in a two-step process. Both glutamate and glutamine play a key role in amino acid synthesis, thus an increase in levels of glutamate and glutamine increase protein synthesis. Glutamate dehydrogenase has a low affinity for NH^+_4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH^+_4, when the concentration of NH^+_4 is high. Glutamate dehydrogenase has a high affinity for NH^+_4, thus the rate of glutamate synthesis increases exponentially under high ammonia conditions. Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Answer:
- Glutamate dehydrogenase has a low affinity for NH+4, and can only catalyze the formation of glutamate from alpha-ketoglutarate and NH+4, when the concentration of NH+4 is high.
- Glutamate is the amino group donor for most transamination reactions involving amino acids, thus an increase in glutamate concentration increases protein synthesis.
Explanation:
Glutamate dehydrogenase (GLDH) is an enzyme found in prokaryotic and eukaryotic cells, which is known to catalyze the reversible oxidative deamination of glutamate (Glu) to alpha-ketoglutarate and ammonia at the same time the oxidation of NADH to NAD. In bacteria, this enzyme (GLDH) is efficient only at high concentrations of the ammonium cation (NH4+), because it has a low affinity for NH4+. Moreover, transamination is a pathway that involves the transfer of an amino group from one amino acid to a ketoacid in order to form new amino acids (this reaction is responsible for the deamination of most amino acids). Glu is the donor of amino groups in most of the reactions catalyzed by enzymes involved in the transamination between an amino acid and an alpha-keto acid. In consequence, in presence of GLDH, a high concentration of Glu will increase the production of new amino acids and therefore also protein synthesis.

DONE
Answer:
The correct answer is - stem cells.
Explanation:
Stem cells can give rise to all tissues and organs in the body. These cells can differentiate into any form of cells, which allows them to repair tissues that have been damaged by various physiological or natural ways
There are two types of stem cells: Adult Stem Cells and Embryonic stem cells.
Cells that are present in the bone marrow or umbilical cord of a newborn baby and can be divided as Hematopoietic, a cell that can form blood cells and the immune system, and mesenchymal that form the body's cartilage, bones, muscles and other.
Embryonic stem cells are found on at blastocyst stage of embryo. These cells can transform into any type of tissue in the human body, which increases their treatment potential.

Among the Quebec Inuit, it was thought that no death is natural. All deaths were seen as the result of warfare, either physical or spiritual, so if a person died, it was thought to be the work on an enemy shaman. As such, deaths were always followed by shamanistic retaliation.
a. True
b. False
Answer:
a. True.
Explanation:
The deaths in Quebec were all due to some spiritual or physical warfare. The people there do not die a natural death due to illness or some other reasons. The people of Quebec are afraid of dying these types of death due to a pain.
In the food web above, if new species of insect were introduced that fed primarily on plantains, how would the following populations be affected? Indicate your answer by increase , decrease or no change and include a brief explanation of your reasoning.
A) greenfly
B) rabbit
C) fox
Answer:
This is a 50/50 answer. I believe it would be fox, sorry if this is incorrect.
Answer:
Greenfly- no change
The greenfly would remain unaffected because it doesn’t rely on plantains.
Rabbit- decrease
The rabbit relies on plantains as food so more competition would result in a decrease in the rabbit population
Fox- decrease
Lesser food means lesser foxes. The foxes prey like the rabbit and mouse eat plantains. If the mouse and fat population goes down so would the fox population.

As you completed this assignment and reviewed the lectures (see the socioecological model lecture and diagram provided), you realized that there are several factors that influenced your own daily food choices. What are they? Explain. Think about the following as you write your response: (essay format for each segment)
1. Individual factors influencing your daily food choices (demographics, other personal factors)
2. Settings (homes, schools, worksites, etc.)
3. Sectors (systems, organizations, and businesses and industries), and
4. Social and cultural norms and values (belief systems, traditions, heritage, etc.).
Additional question: how can the Social-Ecological Model help us with our daily food choices?
Answer:
factors that influenced daily food choices:
biological determinantseconomical determinantsphysiological determinantsphysical determinantssocial determinantsbehavioral determinantsExplanation:
Social -ecological system is the set of different factors which influence our living styles, our dietary habits, our dress choice etc. on a daily basis. In today's world, everything act is done by people are only based on its popularity or followed by trends. Similarly, our daily food choices are also influenced by the trends and our surroundings in which we live. There is the impact of multiple factors on our daily food choices.
Behavioral factors: behavioral factor is the most important factor which have a huge impact on our daily food choice. An individual health condition, behavior, attitude, work routine majorly influence the food choices. An individual personal preferences, likes and dislikes also influenced his food choices.Biological factors: these factors can influence individually as well as globally. Hunger, nutrient requirements, condition of safe food, health conditions are the major biological factors which play major role, when it comes to choose daily food. These factors can affect the global food preferences, for example in the pandemic of convid-19 food choice were similar of every individual globally. Economic factors: availability of food, cost of food, balancing of needs and demands also impacts our daily food choices. If cost are too high of basic food and the availability is only limited to certain people, it automatically impacts on the food choice of an individual. Social Factor: when we talk about social factors these are the group of different small factors like culture, work environment, school, colleges, religious preferences, friends circles, demographic conditions etc. our daily food choices are mostly based on the social factors because our likes and dislikes, meal patterns, our preference of food (cooked, raw, packages, cooking style etc.) Everything based on the impact of the surroundings. In schools and colleges, students are bound to eat what is available or what their friends prefer to eat. Religious backgrounds always choose as per their rulings. Traditional foods, cultural heritages also an impactful factor for our daily food choices.Physiological factors: mental health condition are also one of the important factor which can not be neglected when we choose our food to eat. A healthy individuals preferences will always be different from a sick person.Social-ecological model can help us with our daily food choices by giving us the knowledge of the factors and its healthy impact on our food choices which can lead us to a healthy life and prosperous environment. Smart choice not only make us health but also make the environment healthy for our lives.
Clear-cutting and logging of tropical rain forests causes issues with excess carbon dioxide in the atmosphere and low rainfall. The land that is cleared and used for farming become depleted of nutrients and thus are useless. Do we have any right to tell other countries how to manage their lands, such as rain forests? If we explain the consequences of clear-cutting the rain forests but that government decides to continue with the process, should we interfere?

What is the process in the cell can be disturbed by the destruction of the mitochondria?
a.
nuclear fission
b.
photosynthesis
c.
oxidation of substances organic
d.
crossing-ove
Answer:
The correct answer is - C. oxidation of substances organic.
Explanation:
The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.
The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.

Primary sensory afferent axons have widely varying diameters, and their size correlates with the type of receptor to which they are attached. Write down the axons that are the smallest and the slowest?
Answer:
Smaller and slower axons are those related to temperature, itching and pain.
Explanation:
As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.
