How do you think caffeine will affect the heart rate of humans

Answers

Answer 1

Answer:

Caffeine stimulates the heart's contractions via acting on enzymes in the heart. Caffeine can help natural hormones operate on the heart to release norepinephrine, which has a stimulating impact comparable to adrenaline.

Answers

Through osmosis, water can freely pass the membrane from the most diluted side to the less diluted one. Option a. swell

What is osmosis?

Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the beaker content- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute (glucose). Hence, water can move from the most diluted side to the less diluted one. In other words, water moves from the less concentrated side to the more concentrated side (conserning the solute).

According to this information, the interior of the cell is more concentrated and less diluted than its exterior. Hence, water will move from the extracellular space foward to the cell interior, and the cell will swell.

Option a. swell

why is rna synthesis called transcription and protein synthesis called translation?

Answers

Answer:

They are all part of protein synthesis. But RNA synthesis is called transcription because it is the process of making mRNA from DNA. Protein synthesis is called translation because the transfer of mRNA(which was made in transcription) to amino acids creates a chain of those acids which create proteins.

Explanation:

Transcription: The process of making mRNA from DNA.

mRNA is a type of RNA. m stands for messenger. Synthesis means making so RNA synthesis literally means making RNA which is what the process of transcription does. Additionally for protein synthesis the word simply means making protein which is what is happening in the process.

In the central dogma process, the genetic material gets copied and forms proteins needed for cell structure and functioning.

Transcription is the process of forming RNA from deoxyribonucleic acid. The DNA gets transcribed into ribonucleic acid.

The DNA formed by replication further processes and forms mRNA which is a type of RNA.

The formation of proteins from RNA with the help of ribosomes is called Translation.

In this process, the mRNA and tRNA translate and assemble amino acids into protein chains of the polypeptide.

Therefore, RNA synthesis is called transcription and the synthesis of protein is called translation.

the exchange of genetic material between homologous chromosomes

please help asap test due in 10 min will bomb if I don't have right wander

Answers

I believe the answer is: D - the exchange of genetic material between homologous chromosomes.

Explanation:

In crossing over, sections of DNA move between homologous chromosomes and allows for independent assortment.

Independent assortment states that genes are inherited independently of one another.

For meiosis to occur, the chromosomes contributed by each of the organism's parents are duplicated to form sister chromatids. During meiosis I, the sister chromatids of one parent match up with the corresponding sister chromatids of the other parent (synapsis), or its homologous non-sister chromosome, along the metaphase plate.

Crossing over then occurs. At a point called a chiasma, homologous chromosomes trade genetic information so that each chromosome is complete but has different information.

This random exchange of information is what allows for unique gametes to form and genetic recombination to occur.

In a typical animal, mitosis produces _________, while meiosis produces____________.

Answers

In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.

Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.

This occurs in sex cells such as the sperm and egg cells.

Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.

This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

The reproductive system is an organ system by which humans produce male (sperm) and female (ovule) gametic cells.

Male and female gametes fuse during fertilization to produce a diploid zygote that develops into an adult individual.

In women, the reproductive system is composed of the ovaries, uterus, fallopian tubes, cervix, and vagina.

What happens to plant cells
when they are exposed to
distilled water?

Answers

Contrastingly, when the plant cells are placed in distilled water, the concentration of water molecules is greater out of the cell than it is in the cell and therefore water moves into the cell by osmosis down the concentration gradient.

When plant cells are exposed to distilled water, they undergo a process called osmosis. The cells gain water and the cell swells. Thus, option B is correct answer.

Osmosis takes place when plant cells are submerged in distilled water, which has a lower solute concentration than the cytoplasm of the cell. To balance solute concentrations, water molecules flow through the semipermeable cell membrane. The vacuole of the water that enters the cell enlarges and presses on the cell wall.

The cell becomes hard and inflated due to this internal pressure, also known as turgor pressure. However, excessive water intake might cause cytolysis, which is the process when cells explode. The plant's overall health and cell structure are supported by this natural process of osmosis and turgidity.

C. Sexually reproducing organisms
D. Insects

Answers

Asexually reproducing organisms groups are difficult to define into species using the Biological Species Concept.

Why is it difficult to define a species using the concept of a species?

In summary, the main limitation of the concept of organisms is that they are independent of ectopic speciation and are not applicable to (1) Fossil species. (2) Organisms with asexual reproduction or extensive self-fertilization. (3) Sexual organisms with an open mating system (seed that mates freely).

Asexual reproduction is a type of reproduction that occurs without cell or germ cell interaction. In the case of asexual reproduction, the organism does not need a spouse to reproduce. Organisms that undergo asexual reproduction to produce offspring are called asexual species.
