Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes

Answer:

Explanation:
A process that increases genetic diversity during meiosis
Answer:
During the prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.
What is meiosis?During the prophase of meiosis I, homozygous chromosomes are next to one another and exchange genetic material.
There could be a heterozygous state for a gene if two distinct alleles are present on the same genetic locus on homologous chromosomes. (For instance, an allele for antigen A on one chromosome and an allele for antigen B on another; both are used to determine the ABO blood group.)
Numerous genes are linearly ordered on chromosomes; as a result, some of them may still be heterozygous. (The same person may be heterozygous for the ABO blood group, iris color, and sickle cell anemia).
Therefore, Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

Why are epithelial cells in membranes
packed tightly?
to keep organs connected
to protect organs
to form different layers
Answer:
to protect organs
Explanation:
Epithelial cells are cells found in the human skin. They are tightly packed cells which helps to protect organs in the human body.
The cells are divided into different layers with an inner part and the outermost layer.
The skin is the largest organ of the human body. It protects all organs from the external environment.
Convection causes tectonic plates to move.
A) True
B) False
Answer:
Hope this helps.
Explanation:
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again. So I think false

Suppose you mate a black rooster with a white hen. The feathers of all the offspring are “gray,” a color that is intermediate between black and white. Explain the inheritance pattern in these chickens.
Answer:
Incomplete dominance
Explanation:
The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.

A strand of DNA contains the bases adenine, cytosine, cytosine, and guanine, in that order. Which would be the order of the bases on the opposite strand of DNA?
cytosine, adenine, adenine, and thymine
cytosine, thymine, thymine, and adenine
thymine, guanine, guanine, and cytosine
thymine, adenine, adenine, and cytosine
Answer:
thymine, guanine, guanine, and cytosine
Explanation:
The order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.
DNA and complementary base pairingThe deoxyribonucleic acid (DNA) is a double helix composed of two long chains of sequential nucleotides.
In DNA there are four classes of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine, Thymine).According to the base pair rules of complementarity, Adenine always pairs with Thymine, whereas Guanine always pairs with Cytosine.In conclusion, the order of the bases on the opposite strand of DNA should be Thymine, Guanine, Guanine and Cytosine.

Answer:

source of pergisol
Explanation:
What if climate change is self-sustaining? This is already the case, for example, with melting arctic sea ice. This reflects solar radiation, which allows the ocean, located under the ice, to stay cold. But when sea ice melts, the ocean absorbs heat from the sun, which melts more ice. In general, it is difficult to predict the tipping point where such a feedback loop will engage.
Spread over more than 23,000,000 km2, at the top of the globe, permafrost (permanently frozen ground) could enter such a vicious circle. Normally, up to 4 m of soil and plant debris cover the permafrost. This top layer (called the active layer) normally melts every summer, and freezes in winter. It thus protects the permafrost from the rise in heat outside. But in the spring of 2018, a team working at a research station in Tchersky, Russia, discovered that near-surface land had not frozen over at all during the long, dark polar night.

Why is the dysphotic zone around coral reefs shallower than the dysphotic zone in the open ocean?
There is more oxygen in the open ocean.
The sun is brighter over the open ocean.
There is more nitrogen by the coral reefs.
There is more plankton by coral reefs.
Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.
the rate of photosynthesis can be affected by several factors, such as light intensity, temperature ,water, and carbon dioxide. describe how the lack of water in an environment can affect the amount of carbon dioxide absorbed by the plant
Answer:
Plants need water, so that their guard cells can fill up and become turgid which would allow the stomata to open and gas to exchange. If there is not much water, not much gas exchange can occur hence not much Carbon dioxide can be taken in.
Explanation:
Plants require water for the process of photosynthesis. Plants need water so that their guard cells can fill up and become turgid. This allows the exchange of gases in the stomata.
How does water affect photosynthesis?
During photosynthesis, the plants take in carbon dioxide and water molecules from the air and soil particles. Within the plant cell, this water is oxidized to generate oxygen gas, meaning that it loses electrons, while the carbon dioxide gas is reduced in the chloroplast of the plant cell by gain of electrons to produce carbohydrates. This process transforms the water into oxygen gas and the carbon dioxide gas into glucose molecules (carbohydrates).
Plants need water, so that the guard cells in the plant can fill up and become turgid which would allow the stomata to open and exchange of gases. If there is not much water present in the guard cells, not much gas exchange can occur hence not much of the carbon dioxide can be taken in from the atmosphere.
