Binary fission is the most common form of reproduction in _____.animals
plants
fungi
protozoa

these are the choices but i have no idea what the answer is

Answers

Answer 1

Answer:

The correct answer is protozoa.

Binary fission is a type of asexual reproduction. It is the most general kind of reproduction in prokaryotes, like bacteria. It also takes place in some kind of single-celled Eukaryotes, protozoa, like Paramecium and Amoeba.

In protists, like protozoa, the binary fission is usually distinguished into types, like longitudinal or transverse, on the basis of the axis of cell separation.

Answer 2

Answer:

Binary fission is the most common form of reproduction in protozoa. Therefore, the correct answer is option d.

Binary fission is a method of asexual reproduction in which a single-celled organism divides into two identical daughter cells. Here's an explanation of binary fission and its relevance to protozoa:

Single-Celled Organisms: Protozoa are a diverse group of microscopic, single-celled organisms belonging to the domain Eukaryota. They are found in various aquatic and terrestrial environments.

Asexual Reproduction: Many protozoa reproduce asexually through a process known as binary fission. In binary fission:

The single-celled protozoan organism, which can be quite complex in structure despite being microscopic, undergoes a series of cellular processes to duplicate its genetic material (usually its nucleus).
The cell then divides into two daughter cells, each containing a copy of the genetic material and other cellular structures.
These daughter cells are genetically identical to the parent cell and can function independently as separate organisms.

Significance for Protozoa: Binary fission is significant for protozoa for several reasons:

It is a rapid and efficient method of reproduction, allowing them to increase their population quickly under favorable conditions.
It helps protozoa maintain genetic consistency since the daughter cells are essentially clones of the parent cell.
Protozoa can adapt to changing environments through binary fission, allowing them to thrive in diverse habitats.

Contrast with Other Organisms: While binary fission is common in protozoa, it differs from the reproductive methods of multicellular organisms such as animals, plants, and fungi:

Animals typically reproduce sexually, involving the fusion of gametes from two parents to create genetically diverse offspring.
Plants can reproduce both sexually (through seeds) and asexually (through methods like vegetative propagation).
Fungi reproduce through a variety of methods, including sexual reproduction involving the fusion of specialized sexual structures.

In summary, binary fission is the primary mode of asexual reproduction observed in protozoa. It allows these single-celled organisms to efficiently replicate themselves and adapt to their environment by producing genetically identical daughter cells. This method is essential for the survival and proliferation of many protozoan species.

The graph illustrates the activity level of three common digestive enzymes, across a range of pH values. Which enzyme is likely to be active in the acidic environment of the stomach?A)
pepsin
B)
trypsin
C)
amylase
D)
pepsin and trypsin

Answers

Answer: A) Pepsin

Explanation: Acidic solutions are solutions which provide H^+ ions .More is the H^+ ion concentration, more acidic is the solution.

pH of a solution is defined as negative logarithm of H^+ ions concentration.

$pH =- log{[H^+]}$ or

$pH = log(1)/([H^+])$

Thus lesser is the pH,more is the H^+ concentration and more acidic is the solution.

Thus acidic solutions have low pH and pH ranges from 1 to 7 for acidic solutions.

As can be seen from the graph, enzyme pepsin has highest activity at low pH which means in acidic solutions. As the pH is increasing or the solution is turning basic, the activity of pepsin decreases.

I think amylase as well

In meiosis II what happens during anaphase?

Answers

Answer:

Pulling apart or separation of sister chromatids

Explanation:

Meiosis is a type of cell division that results in four daughter cells with each having half number of chromosomes as the parent cell. It is the cell division that leads to formation of gametes to enable sexual reproduction. Division occurs twice during meiosis because before the two halves of a duplicated chromosome called sister chromatids separate, it still needs to separate homologous chromosome, which is a similar but non-identical pair of chromosome received from both parents. Hence, meiosis occurs in a two step division process i.e. Meiosis I and Meiosis II.

Meiosis II is the mitotic division of each of the haploid cells produced in meiosis I. Note that, homologous chromosomes separate in anaphase I of meiosis I, and further undergoes cytokinesis (division of cytoplasm) to produce two haploid (reduced number of chromosomes) daughter cells.

During anaphase of meiosis II, the individual chromosomes (sister chromatids) separate at the centromeres (point of attachment between two sister chromatids). The separated chromosomes are pulled apart towards each pole of the cell by the spindle fibres.

Meiosis II the chromosomes are pulled to the center of the cell and line up randomly at the equato
Anaphase II the centromere of each chromosome splits -the sister chromatids separate and move to opposite poles

Nicotine acts in the brain by: Multiple Choice increasing serotonin reuptake. enhancing GABA's inhibitory effects. reducing blood flow to the cerebral cortex. first stimulating and then blocking cholinergic receptors.

Answers

Answer:

first stimulating and then blocking cholinergic receptors

Explanation:

Nicotine is a type of stimulant that is chemically alkaloid. It works as the receptor agonist at the nicotinic acetylcholine receptor. It is a type of addictive chemical that increases the blood flow, heart rate and some biochemical reactions of the body. In the brain, it has stimulation as well as blocking effect. Medically, it is used for various purposes such as quitting smoking and some other.

Final answer:

Nicotine stimulates and then blocks cholinergic receptors in the brain, leading to both stimulating and relaxing effects.

Explanation:

Nicotine acts in the brain by first stimulating and then blocking cholinergic receptors. It first acts as a stimulant, increasing the release of acetylcholine, which causes excitatory effects in the brain. Eventually, the cholinergic receptors become desensitized and eventually blocked, leading to a reduction in acetylcholine's activity. This process helps explain why tobacco usage can both stimulate and relax users. When nicotine binds to these receptors, it activates them, leading to the release of dopamine and other neurotransmitters, producing pleasurable effects.
