which dish is your positive control for a cellular response to testosterone, and which dish is your negative control ?

Answers

Answer 1

In a cellular experiment to study testosterone response, the positive control is a group of cells known to respond to testosterone, whereas the negative control is a group of cells known to not respond to testosterone.

The positive control is necessary to demonstrate that cells can respond to testosterone and to establish a baseline for cellular response.The negative control is used to ensure that any response observed in the experimental group is due specifically to the treatment with testosterone and not to other factors, such as the fetal bovine serum (FBS) used for cell culture.

In general, the positive and negative controls are necessary to establish the specificity of the treatment and to guarantee the quality of the results of the experiment. Both controls are essential to establish the specificity of the treatment and to minimize the effects of other factors on the results of the experiment.

lymph capillary permeability is due to minivalves and protein filaments. lymph capillary permeability is due to minivalves and protein filaments. true false

Answers

Lymph capillary permeability is due to mini valves and protein filaments, which are structures that control the passage of molecules across the wall of the capillary. So the statement is True.

The mini valves are pores of small diameter that can open and close to regulate the passage of molecules across the capillary wall, while protein filaments control the size of these pores. The size of these pores depends on the type and concentration of the molecules in the interstitial fluid. Therefore, the size of the pores can be adjusted, allowing the lymph capillary to control the movement of molecules across the capillary wall. This allows the lymphatic system to regulate the movement of substances in and out of the lymphatic capillaries and helps maintain homeostasis in the body.

Answers

The migration of Mormons to Utah would be an example of what type of founder effect genetic drift

What is a founder effect?

Founder Effect refers to a process that occurs when a small subset of the original population becomes geographically isolated from the majority of the population.

Due to their geographic distance from the rest of the population, this subset of people breeds only among themselves, causing the frequency of certain genetic traits to be more common in this isolated population than in the larger population as a whole.In the case of the Mormon migration to Utah, the founder effect is observed.

When the Mormons first migrated to Utah, they were a small group that settled in a new area. They had limited interaction with the rest of the population, which means that genetic traits that were more common among Mormons were more common in Utah's population over time.

This is known as the founder effect.The bottleneck effect is a situation in which a significant portion of a population is destroyed, resulting in a decrease in the genetic variability of the population. In contrast, founder effect is caused by the isolation of a small group of people from the larger population.

which of the following events in a cell would require atp? a.splitting a lipid molecule into smaller parts b.breaking a carbohydrate into individual sugar subunits c.passive movement of molecules through the cell membrane d.linking together amino acids to form a protein

Answers

D. Linking together amino acids to form a protein would require ATP.

ATP, or adenosine triphosphate, is the primary energy currency in cells. It is produced during cellular respiration and provides energy for cellular processes that require energy.

What is ATP?

ATP stands for adenosine triphosphate, which is a molecule that serves as the primary energy source for many cellular processes.

When ATP is hydrolyzed, or broken down, by the enzyme ATPase, it releases energy that can be used by cells to power various processes. This hydrolysis reaction breaks the bond between the second and third phosphate groups in ATP, releasing a phosphate group and forming adenosine diphosphate (ADP).

Linking together amino acids to form a protein requires energy, which is provided by ATP. This process is called protein synthesis or translation, and it occurs on ribosomes in the cell. ATP is needed to supply the energy required for the formation of peptide bonds between amino acids, which are the building blocks of proteins.

Answer:

The modification that occurs to retinoblastoma that will push the cell through the restriction checkpoint is its phosphorylation. This allows the cell to move from G1 to S phase of the cell cycle.

What is Retinoblastoma?

Retinoblastoma is a type of cancer that grows in the retina of the eye. This cancer is one of the rarest forms of cancer and mostly affects children. The condition starts in the cells that develop into retina cells. The retina is the light-sensitive tissue located at the back of the eye.

Modification of Retinoblastoma:

The retinoblastoma protein, or pRB, regulates the progression of the cell cycle from G1 phase to S phase by binding to the transcription factor E2F. When pRB is hypophosphorylated, it prevents E2F from binding to the promoter regions of genes required for DNA replication, resulting in a G1 cell cycle arrest or checkpoint.

The phosphorylation of the RB protein enables the cell to cross the restriction checkpoint and progress from G1 to S phase of the cell cycle. This phosphorylation is carried out by the cyclin-dependent kinases (CDKs), which phosphorylate several different sites on the RB protein.

What important events take place during prophrase 1

Answers

Answer:

Prophase 1 is the first phase of meiosis, which is a type of cell division that produces haploid gametes with unique combinations of genetic material. Prophase 1 is a complex and important stage that involves several key events, including:

Chromosome condensation: The DNA in the cell's nucleus condenses and coils tightly into visible chromosomes, which consist of two identical sister chromatids joined by a centromere.

Homologous chromosome pairing: The maternal and paternal copies of each chromosome come together to form pairs called homologous chromosomes. This process is called synapsis and is facilitated by the formation of a protein structure called the synaptonemal complex.

Crossing over: During synapsis, the homologous chromosomes exchange segments of genetic material in a process called crossing over. This results in the exchange of genetic material between the maternal and paternal chromosomes and increases genetic diversity.

Nuclear envelope breakdown: The nuclear envelope, which separates the nucleus from the cytoplasm, breaks down, allowing the chromosomes to move freely in the cell.

Spindle fiber formation: Microtubules called spindle fibers begin to form and attach to the centromeres of the chromosomes, preparing to pull them apart during the later stages of meiosis.

Overall, prophase 1 is a critical stage of meiosis that allows for the pairing and recombination of homologous chromosomes, leading to the formation of genetically diverse gametes.

why are trees found in areas of high precipitation rather than grasses? why are grasses found in drier areas?

Answers

Trees require more moisture than grasses, which is why they are found in areas of high precipitation rather than grasses.

the protein in biological organisms inculude 20 different kinds of amino acids. what is the minimum number of different types

Answers

There must be at least 20 different tRNA molecules in a cell in order to form proteins. Each of the tRNA molecules has a unique anticodon that pairs with a codon of mRNA and a unique amino acid-binding site that pairs with a particular amino acid. This is necessary for the formation of proteins.

The minimum number of different tRNA molecules that must exist in a cell is 20, as there is one specific tRNA molecule for each of the 20 amino acids. Each tRNA molecule carries the correct amino acid to the ribosome, which is necessary for the formation of proteins.

The structure of tRNA molecules consists of an amino acid-binding site and an anticodon region. The anticodon region of each tRNA molecule is complementary to a codon of mRNA, and the amino acid-binding site is able to interact with an amino acid. The codons of mRNA direct the ribosome to the appropriate tRNA molecule that corresponds to a particular amino acid.

Therefore, since there are 20 amino acids, 20 different tRNA molecules must exist in a cell in order to pair with each of the codons of mRNA. This ensures that the correct amino acid is available for the formation of proteins. Without the correct tRNA molecule, the ribosome would not be able to bring the correct amino acid to the site of protein synthesis.

Amino acids, not proteins, are absorbed; proteins rely on prior digestion to amino acids. Most absorption of amino acids occurs in the jejunum; there is a lesser contribution from the ileum.

Amino acids are absorbed by a co-transport mechanism with sodium ions. Both sodium ion and amino acid combine with a cell surface protein receptor.

There are different receptors for the groups: neutral amino acids, basic amino acids, acidic amino acids

In addition, certain amino acids may have there own specific transporter e.g. proline. The receptor then conveys both molecules to the inside of the cell.
