Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.
Bears and salmon have a predator-prey relationship. What would most likely happen to the bear population if the salmon population increased?
stay the same
decrease
increase
become extinct
Answer:
Increase
Explanation:
When there is enough food there is always excelling Reproduction
Bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option, as bears rely heavily on salmon.
What is the predator-prey relationship?Bears are opportunistic feeders, and their diet varies according to what is available in their environment, and in areas where salmon is abundant, bears rely heavily on this food source to meet their nutritional needs. When salmon populations increase, there is a greater availability of food for bears, which can lead to improved body condition, increased survival rates, and higher reproductive success, and with more food available, female bears can produce larger litters of cubs.
Hence, bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option.

Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous environment? A species that lives in a homogeneous environment is more likely to exhibit phenotypic plasticity. The homogeneity or heterogeneity of an environment does not determine whether a species will exhibit phenotypic plasticity. Only a large population in a homogeneous habitat can exhibit phenotypic plasticity. A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Answer:
A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Explanation:
Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.
Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.
Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.
A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.

A number line going from 16 to 20. An open circle is at 18. Everything to the left of the circle is shaded.
A number line going from 30 to 34. An open circle is at 32. Everything to the right of the circle is shaded.
A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.
Answer:
4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.
Explanation:
It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.
Let the total number employees be e.
Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.
e < 24
Multiply 4 both sides.
ex 4 < 24×4
3e < 96
Divide both sides by 3.
e < 32
Therefore the value of e is less than 32.
In a number line as we approach towards left the the value of integers decreases.
Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.
Since 32 is not included in the solution set, therefore there is an open circle on 32.

Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming techniques?
Answer:
The correct answer is - Rotate the types of crops grown.
Explanation:
Crop rotation is the practice of growing the different types of crops sequentially on the same field to improve nutrients in the soil for better soil health and helps in fighting pest and weed pressure.
Different crops required different nutrients and therefore, rotating crops helps to not exploiting the same nutrients again and again. Rotating crops also helps in removing weeds and pests as different weeds and different pests associate with different crops.

Which of the following molecules is not needed for the Calvin Cycle?
a. CO2
b. ATP
c. NADPH
d. H2O
pls help
Answer:
c. NADPH is the correct answer .
Explanation:
Hey mate..!
NADPH molecules is not needed for the Calvin Cycle.
The correct answer is water as the water molecules are produced during photosynthesis.
Co2 produces the starch from sugar. ATP and NADPH are also used to convert sugar molecules during the Calvin cycle.
Carbon enters the Calvin cycle as CO2 and leaves as sugar. ATP is the power source, even as NADPH is the decreasing agent that provides high-power electrons to shape sugar. The Calvin cycle absolutely produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P).
What is the Calvin cycle?The Calvin cycle is a technique that plant life and algae use to show carbon dioxide from the air into sugar, the meals autotrophs want to grow. Every dwelling element on Earth relies upon the Calvin cycle. Plants rely on the Calvin cycle for power and meals.
Thus it's clear that it has no water needed.

Translate the mRNA codons into the
amino acid sequence.
(DO put a comma and a space between the codons and make sure you spell out the names of amino acids!)
Answer:
mRNA sequence: AUG; GCU; AAU; UGU; UGA
protein sequence: Met-Ala-Asn-Cys-stop codon (Methionine-Alanine-Asparagine-Cysteine-stop codon)
Explanation:
Transcription is the process by which a fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) sequence that is then used to synthesize a protein by the process of translation. In RNA, Adenine bases are replaced by Uracil bases. During translation, each codon (i.e., each triplet of nucleotides of the mRNA) indicates a specific amino acid (according to the genetic code). UGA, UAA, and UAG are stop codons that signal the end or termination of translation.
You are the RN starting your shift on a pediatric unit. You are taking care of a 7-month-old infant who has been alert and behaving in an age-appropriate manner on the previous shift.

A. encourage the parents to keep the room quiet to allow him to sleep.
B. document it and plan to recheck him in an hour.
C. tell his parents to make him wake up because it is not time for him to go to bed.
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding. And can lose alertness and pays less attention to sounds and the baby is always drowsy. The registered nurse has to assess this baby immediately because lethargy could happen because the baby may have an infection or probably have low blood sugar. Therefore the last option is the best option for the nurse to take.
