Which organisms replicate cells by mitosis?

Answers

Answer:

All organisms, both prokaryotes and eukaryotes, can replicate cells by mitosis.

Explanation:

Mitosis is the process of cell division where, from a progenitor cell, two identical daughter cells are obtained. In the human being this process is carried out by somatic cells.

Cell division by mitosis is carried out by all living beings:

Prokaryotic organisms, unicellular, use it as a means to reproduce. Eukaryotic organisms, most of them pluricellular, use it in the processes of growth, development, repair and regeneration of tissues.

All living beings can perform mitosis as a process of cell replication, although with different objectives.

respiration in echinoderms​

Answers

In general, echinoderms typically respire by simple diffusion, using gills or specialized projections, like tube feet or pockets, to circulate water and oxygen through their bodies. Many echinoderms also use a simple hemal system, a series of pockets and tubes that serves almost like a net of veins and arteries.

Would the movement of oxygen through the cells?

Answers

Answer - The oxygen molecules move, by diffusion, out of the capillaries and into the body cells. While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries. Carbon dioxide is brought, through the blood, back to the heart and then to the lungs.

At this stage, the body is dry and mostly bones, cartilage, and dry Skin With oy

Chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow.
What characteristic do these cels most likely share with cancerous cells?
O They form tumors.
O They spread through the blood.
• They divide rapidly.
O They contain a mutation.
A

Answers

Answer:

They divide rapidly

Explanation:

Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.

Answers

The answer that is incorrect is most likely cell wall. cell membrane is what controls what comes in and out of a cell. A cell wall just supports the cell and keeps its shape.

A mutation in a polypeptide with the original amino acid sequence of: Met-Ala-Gln-Arg-Glu-Leu results in a mutant with the sequence: Met-Ala-Gln-Gly-Glu-Leu. Which describes the most likely type of mutation that has occurred?

Answers

Answer:

This question lacks options, however, it can be answered based on general understanding of the topic

The answer is SUBSTITUTION MUTATION

Explanation:

A mutation is any change that occurs in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. One type of mutation is SUBSTITUTION MUTATION, which is a mutation in which one or more nucleotide base is replaced by another in the sequence.

Nucleotide bases are read in a group of three called CODON. Each of these codons specify amino acid. Hence, if the nucleotide base sequence is altered during mutation, the amino acid sequence is altered likewise. In this case where the original amino acid sequence is: Met-Ala-Gln-Arg-Glu-Leu, the mutation affected the nucleotide bases coding for Arginine (Arg), hence changing it to Glycine (Gly).

This means that a base substitution mutation occured, replacing the amino acid Arginine with Glycine in the mutated sequence.

Answers

The food of almost any kind of animal can be traced back to plants. ... Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases and water from the environment and release waste matter (gas, liquid, or solid) back into the environment. Hope this helps :)

The food of come from autotrophic plant to animal through food chain. The energy cycles between the air and soil and plants, animals, and microbes occur by food web.

What are the components of food web?

A food web is defined as the cyclical event of energy transfer among different trophic level of organism.

The major components are primary producers, primary consumers, secondary consumers, tertiary consumers, quaternary consumers

Primary producers are the green autotrophic plants and capture some of the solar energy  and convert it into chemical energy by photosynthesis.

The net primary productivity (NPP) of energy is defined as the rate of photosynthesis minus the rate of respiration of plants.

Primary consumers or herbivores feed on producers constitute  the second trophic level of the food web.

in third tropic level, Secondary consumers eat primary consumers where as  tertiary consumers, quaternary consumers or predators, carnivores or omnivores, which are both plant- and animal-eaters, such as humans.

1. The parts of the flower involved in reproduction are ________ and __________
2. The anthers bear the ___________the microspore mother cells give rise to _______or pollen grains after meiotic cell division.

Answers

Answer:

1. Stamen and pistil

2. Pollen, microspore

Explanation:

The flower is the reproductive part of certain plants called ANGIOSPERMS. They make use of their flower for sexual reproduction. The different parts of the flower work together to achieve a common goal, which is to reproduce, however, they do it in various ways. For example, accessory parts like petals attract pollinators. The major parts of the flower that are directly involved in the reproductive act are STAMEN (male) and PISTIL (female).

The stamen which constitutes a structure called ANTHER bears the pollen grains or microspore, which is made when the microspore mother cells undergo meiotic division. Hence, the pollens are released from the anther of a male flower (stamen), into the stigma of the female flower (pistil).
