Which step occurs first in sexual reproduction
Answer:
In the first stage of sexual reproduction, "meiosis", the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During "fertilisation", haploid gametes come together to form a diploid zygote, and the original number of chromosomes is rest
Explanation:
Answer:
meiosis

The "sides" of the DNA ladder are known as the?
Answer:
The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules, The sugar is a pentose called deoxyribose.
Explanation:
don´t forget to brainllest:)
Answer:
The four nitrogen bases that are found in DNA are Adenine, cytosine, guanine, and thymine. The two molecules that make up the sides of the ladder or the side portion of a DNA molecule are Sugars and phosphates. The molecules that meet across the middle, forming the steps of the “ladder'” are known as Nitrogen bases.

describe non disjunction and the effect it can have on a human
non-disjunction is a pathological event that occurs during the second anaphase in meiosis when sister chromatids are not separated. As a result one of the resulting cells will have 1 extra chromosome and the other will be 1 short. An example of a non-disjunction that can occur in humans is Down syndrome that has a frequency of about 1/1000 people. It is caused by the non-disjunction of the 21st pair of chromosomes.

What change in surface area to volume is expected to result in a faster rate of diffusion?
Answer:
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.
___Ca + ___CuF2---->____ CaF2 + Cu

How does apoptosis relate to cancer cells?
A. In cancer cells, too much apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
C. In cancer cells, apoptosis occurs only when cells grows without proper regulation.
D. In cancer cells, apoptosis occurs only when the cells receive the proper hormones.
Answer: The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation
B
Explanation:
Answer:
B. In cancer cells, too little apoptosis occurs, resulting in malignant cells that will not undergo programmed cell death.
Explanation:

In Mitosis each cell contains how many human chromosomes?
Answer:
46 chromosomes
For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase).

Describe how the behavior of prairie dogs secure the survival of their offspring.
Answer:
Prairie dogs create a safe home for their young by creating underground burrows, which protect them from hailstorms, blizzards, floods, droughts, and fires. The burrow contains many different chambers, including a nursery that is very deep underground. This protects the young from predators as well as changes in the temperature outside. The burrows even include observation posts where they can watch for predators.

have a great day bye luvs
Explanation:
Plants have small holes called stomata on the underside of leaves. Stomata are opened to draw up water from the leaves and allow carbon dioxide in so that the process of photosynthesis can occur. During the process, some water is lost through the open stomata.
Based on this information, which stimulus is most likely to cause the stomata to close?
A. Water volume increasing in the soil
B. Water volume decreasing in the soil
C. Carbon dioxide concentration increasing in the atmosphere
D. Carbon dioxide concentration decreasing in the atmosphere
Answer:
D. Carbon dioxide concentration decreasing in the atmosphere
Explanation:
Since the stomata are opened for the plant to draw the water from the leaves A and B can't be the answer since they rely on needing water from the soil.
Stomata open to also draw carbon dioxide from the atmosphere in order for the process of photosynthesis to occur. This means that they open when there is a high concentration of carbon dioxide in the atmosphere and close when that concentration becomes lower.
What is the difference between a body-cell and a sex-cell mutation in terms of inheritance?
Answer:
Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
Explanation:
Explain unsaturated, saturated, and trans fats.
Answer:
Saturated are full of hydrogen atoms, they´re solid at rooms temp, and they are produced by animals.
Unsaturated are liquid, have double bonds and they are produced by plants.
Trans fats are artificial, they are chemically changed, liquids turned into solids
