how many chromosomes are there in human ovum
Answer:
23 chromosomes
Unlike all the other cells in a human body which are diploid, human sex cells are haploid. That means that both sperm cells and ova are haploid; containing only 23 chromosomes.
Explanation:
have a good day!
(─‿─)
The chromosomes in egg and sperm cells have just 23 chromosomes each.
What is gamete?Male gametes are termed sperm, while female gametes are called "ova." Gametes are an organism's reproductive cells, also referred to as "gender cells." Since gametes are haploid cells, each chromosome is present in one copy per cell.
Unfertilized reproductive cells are called gametes. A zygote is an egg that has been fertilized. Gametes are always haploid cells since they are a byproduct of meiosis.
Zygote is a diploid structure because it results from the fusing of a male and female haploid gamete.
Similar to a sperm, an egg has 23 chromosomes total, which is half the number found in a normal cell.
The resultant embryo will therefore have the typical 46 chromosomes in total after an egg and sperm join during fertilization.
Thus, there are 23 chromosomes in human ovum.

How does gene regulation relate to organism complexity?
Answer:
Organisms that are more complex, such as eukaryotes, have cells that are specialized for specific functions. Gene regulation needs to be more complex to produce these specialized cells for complex organisms.
Hope this helps!
More complex organisms such as eukaryotes have cells that are specialized for specific functions where gene regulation needs to be more complex for complex organisms to produce these specialized cells.
What is Gene regulation?The process of turning genes on and off, defined as gene regulation which is an important part of normal development. For example, genes turn on and off in different patterns during development to make a brain cell look and function differently than a liver cell or a muscle cell.
Gene expression is controlled at two levels which is transcription which is controlled by limiting the amount of mRNA that can be produced from a particular gene and the second control is through post-transcriptional events which allow the translation of mRNA into protein.
Thus, more complex organisms such as eukaryotes have cells that are specialized for specific functions where gene regulation needs to be more complex for complex organisms to produce these specialized cells.

Why do mutations code proteins?
Answer:
A nonsense mutation is a genetic mutation in a DNA sequence that results in a shorter, unfinished protein product. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop signal (stop codon).

The given image shows the relationship between different structures in a plant and their functions.
What are the structures of plants and their functions?
There are various plant parts, each with its unique characteristics and functions to do. Each one of them plays a vital role in maintaining a healthy ecology and environment.
The parts of the plant include
Roots: The most crucial component of a plant is its roots. They are located underground and make up a plant's root system. They are responsible for holding the plant in place with the soil. They serve as an anchor that the plant uses to keep itself steady. By soaking up water, nutrients, and minerals from the soil, they also control the health of the plant. A plant can grow as a result of these. Additionally, they keep food supplies for later use.Stems: It is the second most crucial component. It rises above the ground, starts out green, and eventually turns brown as it gets older. They consist of leaves, fruits, and flowers and sustain the plant's stalk system. They support the framework and structure of the plantLeaves: Chlorophyll, which is responsible for the synthesis of plant food, can be found there. To prepare the food, it makes use of water, carbon dioxide, and sunlight. A leaf is further divided into three main parts: the petiole, leaf base, and lamina.Flowers: There are certain plants that do not have flowers. They have a vibrant, peaceful aesthetic. They are the plant's reproductive system. Petals, sepals, stamens, and pistils are its four main constituent components.Fruits: Fruit production is carried out by flowering plants. After fertilization, the fully developed ovary transforms into a fruit. They develop into a seed first, then a fruit.Learn more about plants here:

B) How does fertilization increase genetic diversity in a diploid organism?
C) How does independent assortment increase genetic diversity during meiosis?
D) How many potential combinations result from chromosomes alignment during metaphase I?
E) How does chromosome methylation result in silencing specific genes during gamete formation?
According to the random arrangement of homologous chromosomes in the equatorial plane, the correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?
How does the random arrangement of tetrads occur?During metaphase 1, chromosomes' homologous pairs migrate to the equatorial plane. Once there, they randomly aline facing their kinetochores to the opposite poles.
The random arrangement of tetrads is different in every cell going through the meiosis process. This is because there is no equal alinement between two cells.
When tetrads arrange in the equatorial plane, there is no predetermined order. Each homologous chromosome of each tetrad faces any of the poles and then migrates to it while separating. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell.
This random order in the equatorial plane is what introduces variation into the gametes.
The correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?

Earth has gone through many cycles of ice ages followed by periods of warmer climate. How might these cycles be related to patterns of solar output and patterns of change in Earth’s motion in space?
Answer:
They both go back and forth, such as the climate going from hot to warm, and the tectonic plates of the earth going from closed 300 million years ago to spreading far apart now.
Both of them oscillate, as seen by the earth's tectonic plates, which went from being tightly packed 300 million years ago to spreading widely at the moment.
What is tectonic plate?Tectonic plate is defined as the lithosphere is made up of sections or parts of the upper mantle and crust of the earth. Starting around 4 billion years ago, cooler parts of the Earth's crust were forced downward into the warmer upper mantle, damaging and weakening the surrounding crust. According to the authors, this cycle repeated itself until the weak spots established plate borders.
Slow variations in the Earth's orbit start and conclude these ice eras. However, variations in CO2 concentrations in the atmosphere also play a significant role in driving both cooling at the start of ice ages and warming at their end. During the last ice age, the average global temperature was around 4C lower than it is now.
Thus, both of them oscillate, as seen by the earth's tectonic plates, which went from being tightly packed 300 million years ago to spreading widely at the moment.

What regulates breathing rate and how does the body sense when to breath?
Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).

The concept of induced fit refers to the fact that a. Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation. b. When enzymes bind substrates, the substrates are bought into proximity to make a chemical reaction favorable. c. When a substrate binds to an enzyme, the enzyme induces a loss of water from the substrate. d. When a substrate binds to an enzyme, free energy is released due to non-covalent interactions.
Answer:
Option A, Substrate binding may induce a conformational change in the enzyme, which them brings catalytic groups into proper orientation.
Explanation:
Induced fit concept refers to introduction of continuous change of enzyme conformation on substrate binding. This change in the shape of enzyme either inhibit or enhance the activity of enzyme. This makes the enzyme catalytic and hence lower the activation energy thereby increasing rate of reaction.
