What would be the expected nuclear dna content of a primary spermatocyte in the same organism?.
1.65 picogram(s), that expected nuclear dna content of a primary spermatocyte in the same organism.
In a gamete (i.e. sperm or egg), the quantity of DNA is 1c, and the range of chromosomes is 1n. Upon fertilization, each the DNA content material and the range of chromosomes doubles to 2c and 2n, respectively.Because they're produced with the aid of using mitosis, number one spermatocytes, like spermatogonia, are diploid and feature forty six chromosomes.
Each number one spermatocytes is going thru the primary meiotic department, meiosis I, to provide secondary spermatocytes, every with 23 chromosomes (haploid).A unmarried number one spermatocyte offers upward thrust to 4 sperms after meiosis. Primary spermatocyte undergoes first meiotic department to provide secondary spermatocytes (haploid). The secondary spermatocytes produce 4 haploid spermatids after the second one meiotic department.

Which BEST describes how metabolism is regulated eukaryotes? A. Starting and stopping metabolic processes are voluntary actions. B. Metabolism increases when the surrounding environment is temperature regulated. Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition. Metabolic processes are the most highly regulated in bacteria.
Answer:
Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition.
Explanation:
Eukaryotic metabolic regulation refers to the mechanisms by which metabolic anabolic and catabolic pathways are modulated in eukaryotic organisms. Anabolic enzymes are involved in the biosynthesis of molecules, while catabolic enzymes are involved in degradative pathways. Thus, enzymes regulate metabolic pathways by catalyzing chemical reactions at their corresponding rates of reaction. Moreover, feedback inhibition refers to those mechanisms occurring when one enzyme is inhibited by the end product of the metabolic pathway, enabling cells to regulate these products.
antidiuretic hormone is important in maintaining homeostasis in mammals. adh is released from the hypothalamus in response to high tissue osmolarity. in response to adh, the collecting duct and distal tubule in the kidney become more permeable
Plasma osmolarity, or the concentration of solutes in blood, is the primary factor influencing antidiuretic hormone release.
Osmoreceptor neurons, which sense osmolarity in the hypothalamus, then trigger the release of antidiuretic hormone from the neurons that sense osmolarity. Osmoreceptors do not activate and antidiuretic hormone secretion is reduced when plasma osmolarity falls below a certain threshold. Ever-vigilant osmoreceptors perceive an increase in osmolarity over the threshold as a stimulus to activate the neurons that release antidiuretic hormone. The concentrations of antidiuretic hormone climb sharply and linearly with rising plasma osmolarity, as seen in the figure below.
Antidiuretic hormone release and thirst have an intriguing similarity. Although most likely not the identical ones, both occurrences seem to be triggered by hypothalamic osmoreceptors.

How is the excess energy of a lipid stored?
a as sugar
b an enzyme
c as protein
d as a fat
Answer:
(D) As a fat.
Explanation:
Lipids and fat are related to each other. Excess lipids are always going to end up as just your fat in the body sitting there unless you do some physical activity to burn that fat off by exercise.
* It cannot be sugar as it relates to carbohydrates. This gives immediate-bursts of energy.
* It cannot be enzyme as it create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
* It cannot be protein as it relates to amino acid. This is for growth and development of the body.

Which of the following mutations will not result in a change to the amino acid sequence of a protein?
A)Frameshift mutation
B)Silent mutation
C)Neutral mutation
D)Nonsense mutation
Answer:
B)Silent mutation
Explanation:
A Silent Mutation is defined as a point mutation that does not change the amino acid. This occurs because more than one codon can code for the same amino acid. So while the protein was changed in the end there were no large-scale effects to the organism. This is why it is called a "silent" mutation because you cannot tell anything changes and there are no side effects.

D.) It releases energy by breaking down glucose
Explanation:
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose...in cellular respiration, oxygen is used to break down glucose releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store the chemical energy for future use. For the most part, the planets living systems are powered by this process. Photosynthesis happens in regions of a cell called chloroplast.

Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body.
Sickle cell disease is caused by an abnormal type of red blood cell gene inherited by the parents. What is the name for different forms of the same gene?
Answer:
An allele
Explanation:
Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome

ants that become immune to ant insecticides and are therefore able to multiply are an example of: please choose the correct answer from the following choices, and then select the submit answer button. answer choices natural selection. interaction. mutations. epigenetics.
Natural selection is one of the evolutive forces. It can select beneficial alleles, which are the product of mutations, and fixate them in the population. Option A. Natural selection.
What is natural selection?
Natural selection is one of the evolutive forces. It acts by selecting beneficial alleles and increasing their frequency in the population.
It results from the interaction between phenotype and environment, which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude can be defined as the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Aptitude must be significant to the natural selection act in its favor.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.
Individuals exposed to new selective pressures need to adapt to survive. Under these environmental conditions, individuals suffer mutations that lead them to avoid them. Since these mutations are beneficial, they are selected by Natural Selection, fixated in the genotype, and transmitted to the following generations.
Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
In the proposed situation,
1) ants were exposed to insecticides.
2) probably many of them dies, but some of them mutated and managed to survive
3) since this mutation was benefitial, it was selected by natural selection.
4) ants carrying this mutation got to reproduce and the mutation spread in the population.
Selective agent: insecticide.Ants response: mutation that lead to survivalThe correct option is then A. Natural selection.
