Answer:
b
Explanation:
It was important that Mendel did not limit his study to just the F1 generation because parental traits that were not observed in the F1 reappeared in the F2.
For example, in across involving a true-breeding yellow seedcoat pea plant and a true-breeding green seedcoat pea plant, all the F1 offspring would be yellow provided that the yellow seedcoat is dominant over the green seedcoat. The green seedcoat trait will only reappear in F2 offspring.
If the breeding experiment is limited to just the F1 generation, of course, the parental green seedcoat trait will not surface at all.
The correct option is b.

Which of the following characteristics are DNA specific characteristics?
a) sugar is missing an oxygen
b) double stranded
c) found only in the nucleus
d) features the bases G,T,A and C
Answer:
a, b, and d
Explanation:
The correct options would be options a, b, and d.
The DNA is primarily made up of 3 components, namely:
Deoxyribose pentose sugar: a sugar that is missing an oxygen, and hence, the prefix 'deoxy'.Phosphate group.Purine and pyrimidine bases. The purine bases include Adenine (A) and Guanine (G), while the pyrimidine bases include Cytosine (C) and Thymine (T)The DNA consists of two strands that are linked together through a hydrogen bond. They are usually found primarily in the nucleus and organelles like mitochondrion and chloroplast of eukaryotic organisms. However, due to the absence of nucleus in prokaryotic organisms, DNA is found within the cytoplasm.
Hence, the correct properties of DNA according to the question are:
sugar is missing an oxygendouble strandedfeatures the bases G, T, A, and CHow could this statement be revised to make it a hypothesis? Fish meal is safer than artificial fertilizers, but it does not make plants grow. Fish meal is a better fertilizer than artificial fertilizer because fish meal is natural. Plants that are fertilized with fish meal will grow taller than plants that receive artificial fertilizer. Plants that receive artificial fertilizer will be better than plants that receive fish meal.
Just take out the fluff.
Plants that are fertilized with fish meal will be healthier for plants than the plants that receive artificial fertilizer.
Or make one of those If, Then, Because statements.
If a plant is fertilized with fish meal rather than artificial fertilizer, then the plants will be overall healthier because fish meal is natural compared to the artificial fertilizer.

In DNA , what base pairs with cytosine? adenine guanine cytosine thymine
Answer:
guanine
Explanation:
IN DNA guanine make a base pair with cytosine and thymine make a base pair with adenine
In DNA, cytosine binds with guanine in the opposite strand. Therefore, option "B" is correct.
What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.
DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, nucleotides are the functional units of DNA.

What is one benefit of cutting off the unopened flower buds after cross-pollination the open flowers in Wisconsin Fast Plants
Answer:
Plants will no longer use the resources to produce flowers but will convert those resources to produce seeds
Explanation:
Wisconsin Fast Plants are variety of Brassica rapa that was developed in order to improve the ability of cruciferous crops to resist to diseases.
After cross pollination( transfer of pollen from another to stigma of two different plants), using cut method, it will be difficult to close the flower bud that was cut, the resources or nutrients that will be needed to produce another flower will be use to produce seeds because the flower bud cannot be close and the bud are exposed as new flowers.

When sugars are broken down to produce usable energy for cells, a large amount of heat is released. Explain how the water inside a cell helps to keep a cell’s temperature constant.
Answer:
Explanation:
This is due to the fact that water has high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.
General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.
Since large hydrogen bonds held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.

O blood is recessive to AB blood. What possible blood types could result from parents with O and AB Blood?
Answer:
Parents having blood type AB and O can produce offsprings having blood group A or Bbut not O
Explanation:
The possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.
What is blood?Blood is defined as a fluid that distributes oxygen and nutrients to cells while also removing carbon dioxide and other waste materials.
There are three types of blood cells.
RBC - RBC stands for red blood cells. They are defined as a kind of blood cell present in the blood that is produced in the bone marrow. WBC - WBC is also called white blood cells. They are defined as a kind of blood cell present in the blood and lymph tissue that is produced in the bone marrow.Platelets - Platelets are defined as the cells that circulate in our blood and link together when they detect damaged blood arteries.Thus, the possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.

You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat, and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. Assume HWE.
The question is incomplete. Here is the complete question.
You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. What is the allele frequency for the light coat allele and the dark coat allele? How many of the dark coated individuals do you expect to be heterozygotes at the coat color gene? Assume the population is at H-W equilibrium.
Answer: Allele frequency for light coat: q = 0.3;
Allele frequency for dark coat: p = 0.7;
There will be 42 heterozygote;
Explanation: A population in H-W equilibrium is a population which doesn't change from one generation to the next if there are no disturbing factors, as migration or mutation.
It follows the equation: [tex]p^{2}+2pq+q^{2}=1[/tex].
p represents the frequency of the dominant allele;
q represents the frequency of the recessive allele;
2pq represents heterozygote individuals;
The sum of frequencies of both alleles must be 1, i.e.: [tex]p+q=1[/tex]
For the population of squirrels:
Frequency of recessive allele[tex]q^{2} = \frac{9}{100}[/tex]
[tex]q = \sqrt{\frac{9}{100}}[/tex]
q = 0.3
Frequency of dominant allele[tex]p+q=1[/tex]
[tex]p=1-q[/tex]
[tex]p=1-0.3[/tex]
p = 0.7
Frequency of heterozygote2pq = 2*0.7*0.3 = 0.42
In a population of 100 individuals: 0.42*100 = 42
The allele frequency for the light coat is 0.3; for the dark coat is 0.7.
It is expected to have 42 heterozygote individuals in this population.

The nuclear DNA content of a single sperm cell in Drosophila melanogaster is approximately 0.18 picogram. What would be the expected nuclear DNA content of a primary spermatocyte in Drosophila
Answer:
The correct answer is - 0.72 pg.
Explanation:
A we know that, genetic material present in one primary spermatocyte divides in between four sperm cells that means that each sperm cell has 25 percent of DNA or genetic material of the primary spermatocyte.
Given:
1 sperm cell = 0.18 nuclear DNA
So,[tex]DNA content of one sperm cell = \frac{\text DNA content of primary spermatocyte}{4}[/tex]
0.18*4 = DNA content of primary spermatocyte
DNA content of primary spermatocyte = 0.72 picogram
