All of the following statements support the cell theory EXCEPT?
Answers
All of the following statements support the cell theory except all cells contain a nucleus. Thus, the correct option for this question is B.
What is the Cell theory?The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.
All living organisms whether plants or animals are made up of cells. A cell is the smallest unit of all living organisms. It is the basic structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.
According to the three assumptions given above, the one which is not matched as per the options is that all cells contain a nucleus.
Therefore, the correct option for this question is B.

The statement that is not considered as cell theory is all cells contain a nucleus. The correct option is L.
What is cell theory?Cell theory is basically a biological theory first given in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.
According to the cell theory, all biological organisms are made up of cells; cells are the basic unit of life, and all life evolved from preexisting life.
The cell theory is now so well-established that it serves as one of biology's unifying principles.
Theodor Schwann proposed the classical cell theory in 1839. This theory is divided into three parts. The first section asserts that all organisms are made up of cells.
Thus, the correct option is L.

Researchers are studying the abnormal activity of kinases in relation to cancer. Theoretically, how might researchers use signal transduction pathways to influence the environment of cancer cells for treatment? (3 points)
Disrupt the function of protein kinases involved in cell cycle regulation
Inactivate epinephrine receptors on cancer cells
Stimulate production of cAMP in cancer cells
Alter G protein-coupled receptors involved in cell cycle regulation to be active in the absence of their normal signaling molecules
Answers
Answer:
I am pretty sure that the answer is A.
Explanation:
Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.
I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!
Consider the overall shape of these cells.
Which geometric shape is the best model for these cells?
Answers
The geometric shape that will best model the cells would be a flat round disc.
Modeling cells
The image is that of a structure containing many cells that are similar in appearance, most likely a tissue.
Each cell can be seen to be somewhat round in shape, typical of many animal cells.
Thus, in order to model such cells, flat round discs will be ideal. Using any other shape will be totally out of place.

A. Axons
B. Mitochondria
C. Dendrites
D. Cell bodies
Answers
Answer:
C
I just didnt do it
Explanation:
Axon is the part of the nerve cell which would be expected to be labelled which can be seen by washing TTX onto a neuron. Thus, the correct option is A.
What is Tetrodotoxin (TTX)?
Tetrodotoxin (TTX) is a natural toxin which interferes with the function of voltage-gated sodium channels in the cell membrane. Tetrodotoxin blocks the sodium permeable pore in the membrane by binding tightly to a specific part outside the channel proteins and block all the sodium-dependent action potentials in the membrane.
Applying TTX to a neuron would block all the impulses in the neuron, preventing it from firing action potential, regardless of the impulse. Labeled TTX could be visualized on the cell's axon, where the voltage-gated sodium channels are concentrated.
Therefore, the correct option is A.

Answers
Explanation:
The process of cell division by which most of cells divide for growth is called mitosis.
In this process, each cell called mother cell divides to form two identical daughter cells. The daughter cells have the same number of chromosomes as mother cell. It helps in growth and repair of tissues in organisms.
Specific cells of reproductive organs or tissues in animals and plants divide to form gametes., which after fertilisation give rise to offspring.
They divide by a different process called MEIOSES.Which involves two consecutive divisions. When a cell divides by meiosis it produces four new cells instead of just two .
The new cells only have half the number of chromosomes than that of the mother cells.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy
Answers
Answer:
the other 60% of energy is stored away for further use in the cell
Explanation:
i hope im right
In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.
How does ATP form from glucose?Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.
Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.
To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain. The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .
Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.

The diploid number of chromosomes in a species is always what
Answers
A diploid cell always contains two complete sets of chromosomes, which is described as 2n.
What is a diploid cell?Two complete sets of chromosomes are present in a diploid cell. The majority of human cells are diploid, with 23 chromosomal pairs totaling 46 chromosomes. This consists of a pair of sex chromosomes and 22 pairs of autosomes. The mother and father each contributed one copy of each pair of chromosomes to the individual.
Through the process of mitosis, diploid cells replicate and maintain the same number of chromosomes by making a copy of each chromosome and dividing their DNA equally among their daughter cells.
Blood cells, skin cells, and muscle cells are examples of diploid cells. These cells are called somatic cells. Different organisms have different numbers of chromosomes.

the frequency of the white alleleb alleles) for the moth-coloration gene in the
population

200
Submit
Request Answer
Answers
Answer:
0.2 (or 20%)
Explanation:
The allele frequency can be calculated by counting how many times an allele appears in a population and then by dividing this number by the total number of alleles of the gene. In this case,
- Genotype BB = 30 moths >> 60 copies of the B allele
- Genotype Bb= 12 grey moths >> 12 copies of the B allele and 12 copies of the b allele
- Genotype bb= 3 white moths >> 6 copies of the b allele
The total number of copies of the gene is:
Dominant (B) allele = 60 (BB genotype) + 12 (Bb genotype) = 72 B alleles
Recessive (b) allele = 12 (Bb genotype) + 6 (bb genotype) = 18 B alleles
Then, 72 + 18 = 90 alleles
Allele frequencies:
Dominant (B) allele = 72/90 = 0.8 (or 80 %)
Recessive (b) allele = 18/90 = 0.2 (or 20%)
The frequency of the white allele b alleles for the moth-coloration gene in the population - 40%
The frequency of an allele can be calculated by dividing the number of times the allele of interest is observed in a population by the total number of copies of all the alleles at that particular genetic locus in the population
Total number of b alleles = number of alleles present in recessive bb + number of alleles present in heterozygotes Bb
Number of bb individuals = 3 Number of b alleles present in bb = 3 × 2 = 6 Number of Bb individuals = 12 Number of b alleles present in Bb = 12 × 1 = 12 Total number of b alleles = 6 + 12 = 18the frequency of an alele = 18/45
= 40%
Thus, the frequency of the white allele b alleles for the moth-coloration gene in the population - 40%
