Answer: An example of a specific case is when a skin lesion occurs. Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other. The spindle fibers are structures formed by microtubules extending from one pole to another to orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase.

Explanation:

Mitosis is a process of cell division that occurs in eukaryotic cells, i.e. cells that have a nucleus where their genetic material is located. This process generates two identical cells with the same DNA, that is, with two identical nuclei, so it does not provide genetic variability except in case of specific mutations. The objective of mitosis is cell multiplication while preserving genetic information. But in general, in mitosis there is an equal distribution of the cell nucleus as well as the rest of the cell content.

The phases of mitosis are as follows:

Mitosis is then a cellular process that occurs in multicellular organisms to repair damaged tissue, or for growth or development. An example of a specific case is when a skin lesion occurs. When a person suffers an injury, many reactions take place in the repair process to repair the damage including inflammatory, proliferative, and remodeling phases.  Through mitosis, new skin cells are generated to repair damaged tissue. These cells have to be genetically identical to each other, to have the same genetic fingerprint and the same function.

The spindle fibers are structures formed by microtubules extending from one pole to another. The kinetochore microtubules attach to the kinetochore, a structure that forms at the centromere of each duplicated chromosome, and orient the duplicated chromosomes in the spindle, bringing them to the position they occupy during metaphase and attracting the newly separated chromosomes to the poles during anaphase.

Spindle fibers has a great contribution in the process of mitosis.

The spindle fibers help to ensure the products of mitosis which is two identical cells with a full set of chromosomes due to attracting the chromosomes towards the poles. Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres and drag the chromosomes towards the pole.

This movement of chromosomes leads to the formation of one parent cell into two daughter cells having equal and same set of chromosomes so we can conclude that spindle fibers has a great contribution in the process of mitosis.

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

What is an obligate anaerobe?: An organism, such as a bacterium, that can live only in the absence of oxygen.

How do obligate anaerobe like Bacteria C get energy?: Obligate anaerobes metabolise energy by anaerobic respiration or fermentation. In aerobic respiration, the pyruvate generated from glycolysis is converted to acetyl-CoA. This is then broken down via the TCA cycle and electron transport chain.

Explanation:

Depends on the biosphere of the other planet, any living thing on another planet would adapt to that planets resources, atmosphere, and climate. SO if that planet was almost identical to ours then maybe? We still have to factor in speed of evolution and whether or not they are put through the same events or big changes that earth life has been put through. I hope this helps!

Answer:

50%

Explanation:

Based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.

A pie chart can show the method by which a total amount can be divided between the levels of a categorical variable as a circle is divided into radial slices.

Each categorical value is corresponding to a single slice of the circle, and the size of each slice, both in the area and arc length, is indicative of the proportion of the whole that each category level will take.

Pie charts have comparatively limited cases of use this is encapsulated particularly accurately according to its definition.

So, for the utilization of a pie chart, one must have some kind of a whole amount that is divided into a number of distinct parts. These are represented by various sections.

Therefore, based on this chart, the approximate percentage of the total items that result from the action of people is 70% - 80%.

Answer:All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.

Explanation:

The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar

The bacteria living in a colony is aunable to perform the conjugation as they have less chances of survivial due to the colony is less genetically divere. Thus the option C is correct.

This is a process wherein organism of the same species like the bacteria, exchange the nuclear mating materials during a temporary union and are capable of transferring one consent form from one organism to another. Thus the lack of genetic variation will lead to fewer chances of species survival.

C4 plants are the organisms which save water by turning carbon dioxide into a special carbon compound before carrying out photosynthesis. Thus, the correct option is B.

A C4 plant is a plant which utilizes the C4 carbon fixation pathway for carbon dioxide fixation. C₄ carbon fixation pathway or the Hatch-slack pathway is one of the three known photosynthetic processes of carbon fixation in higher plants. C4 plants are characterized by the following features such as going through the C4 carbon fixation pathway. This pathway takes place when the carbon dioxide gas is first bound to the phosphoenolpyruvate molecule in the mesophyll cells. Then, the process proceeds to the Calvin Cycle in plants.

C4 plants have a special type of leaf anatomy which is known as Kranz anatomy. These plants can tolerate high temperatures, they show a response to high intensities of light, they also lack a process called photorespiration and have greater productivity of biomass than C3 plants and CAM plants.

Therefore, the correct option is B.
