Answer:
9/256
Explanation:
According to Mendel's experiments the results for the heterozygous are in the ratio 3:1
As each gene is considered separately and the multiplication rule is used. Therefore the probability of getting a solid color would be 1/4 and black fur would be 3/4. Similarly the probability of getting the colored fur is 3/4 and getting a piebald( white patches) is 1/4
Then the combined probability is (1/4*3/4*1/4*3/4)= 9/256

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 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.

This is the sample response btw
how would the pattern of apoptosis differ in a duck’s webbed foot compared to the pattern of apoptosis in a mouse’s foot? Explain
Answer:
A duck's foot is webbed and the chicken's foot is not
Explanation:
The difference is due to apoptosis.Ducks have webbed feet because the cells between their toes do not undergo apoptosis
Apoptosis is a form of programmed cell death. It is the result of the self-destruction mechanisms that is started when the cells respond to a certain stimulus that leads to the destruction of the cell.
The duck's foot is webbed and chickens food is not a sign of swimming ability. The ducks have webbed feet as their foot don't undergo apoptosis. Hence they have webbed.Learn more about the apoptosis that differs in a duck’s webbed foot.

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.

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.
Review the water cycle diagram below. What effect would removing the precipitation stage have on this environment?

D) There would be increased surface runoff and groundwater discharge.
Answer: c
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).

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

Answer:

Explain how the Naked DNA exploits vector's DNA ability to make a vaccine.
Answer:
DNA vaccines consist of DNA vectors or plasmids (small double-stranded DNA rings originally derived from bacteria, but unable to cause infection) into which the genes encoding one or more immunizing proteins of the infectious agent have been inserted causing the disease to be prevented.
Explanation:
Vectors are the functional unit of naked DNA vaccines. Genes that encode the proteins of interest and are of bacterial origin are inserted into these vectors. Bacterial plasmids are circular DNA molecules that self-replicate extrachromosomally in bacteria. The genes encoded in these plasmids are under the control of promoters, almost always of viral origin. When a plasmid is introduced into the cell it translocates to the nucleus, where transcription of the transgene begins; the transcripts are then taken to the cytoplasm and translated there. The newly synthesized proteins are degraded in the proteasome to 8-10 amino acid peptides, which are transported to the endoplasmic reticulum. Peptides of high affinity with their respective MHC I molecule stabilize and enter the secretory pathway, thus reaching the cell surface, where they are coupled with the T-lymphocyte receptor (TcR) present on the surface of T lymphocytes cytotoxic drugs (CD8 +) to induce their activation.

What is the relationship between water clarity and orca survival?
Answer:
Direct relationship.
Explanation:
There is a direct relationship between water clarity and orca survival because the survival of orca depend on the quality of water. If the water quality is good and clean, the orca survival rate increases whereas if the water quality decreases due to pollution, the orca survival also decreases. The chemicals drained into the water bodies is the main cause of lowering orca survival rate so we can say that both have direct relationship.
There is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.
Note the following about Water Clarity and how it affects aquatic life:
Water clarity refers to the measure of how deep light can penetrate through water.Suspended particles and soil on water can reduce the level of light penetration in aquatic ecosystem.Light is needful for the growth of aquatic plants, which produce oxygen for other aquatic.Aquatic plants also provide habitat for fish and other aquatic life like the orca.Clearer waters promote growth and survival for aquatic life including the orca.Therefore, there is a direct relationship between water clarity and orca survival because, the clearer the water, the higher the survival rate of orca.

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
