Thanks for the question,

To classify organisms, scientists use similarities and variations among species. typically these variations area unit simple to ascertain, like whether or not associate animal has fur, feathers, or scales. There area unit seven main assortment ranks: kingdom, phylum or division, class, order, family, genus, species.

The answer to the following question is-

Pros-

- Renewable.

- doesn't need fuel.

- Emission-free

- A trustworthy plant can endure 100 years.

- High performance

- reliable results

- can perhaps act as a storm surge barrier.

- Local rather than global environmental effects

Cons

- costly to construct

- extremely specific to place (only 20 sites identified with high potential)

- Requires non-continuous, grid-backup, or storage

- Barricades might prevent access to open water

- can alter the tidal level in the vicinity.

- Fish, marine mammals, and birds are affected

- upends normal tidal cycles

- reduces the salinity of tidal basins

- collects trash, waste, and pollution close to the coast

- decreases ocean kinetic energy

Tidal power or tidal energy is converted into usable types of power, primarily electricity, using a variety of techniques.

Answer:

mitosis

Explanation:

The cellular process that enables the cells to grow and develop into tissue is mitosis.

Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.

Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by mitosis so as to replace the damaged cells due to the injury. By doing so, the injured area heals.

Answer:

The structure shown by the red arrow is cell membrane.  

In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:  

1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.  

2. It prevents toxic components from entering the cell.  

3. They distinguish essential but incompatible metabolic procedures conducted within the cell.  

Explanation:

The function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).

In conclusion, the function of the structure identified by the red arrow is to store the genetic material (this structure is the cell nucleus).

Changes is macro molecule structures are expected among other things.

There would be significant changes to proteins and carbohydrates if the Earth were built on a tiny non-polar lipid rather than water. Basic alterations in an organism might include solubility, catabolism, metabolism, and absorption. Because there aren't enough dissolved media, a lot of water-soluble material would become immobile.

However, other stuff that is soluble in fat will be very mobile and well absorbed. Sessile organisms that rely on nutrients that are dissolved in water for absorption, such as trees, will lose this capability. Finally, abiotic variables like precipitation and rock weathering will be affected. There will no longer be polar cap freezing or ice melting, and there will be an influx of a non-evaporating liquid.

Indians may closely resemble Europeans in terms of biological traits due to genetic allele frequencies.

The oldest skeleton from Europe that has been found so far is anatomically modern and dates to between 34,000 and 36,000 years ago. It was found in Romania's Carpathian Mountains. Conclusions drawn from the fossil evidence are supported and expanded by data already available on human genetic variation.

The conventional racial divisions, according to some observers, is biologically and genetically justified by these patterns of variation. According to their claims, the distribution of humans among sub-Saharan Africans, European, West Asians, and North Africans, Eastern Asians, Polynesians and other Oceanian residents, and Native Americans largely corresponds to the grouping of the continents.

Answer:

Cancer cells are immortal and keep on dividing for an unlimited number of times. Cancer cells pile on top of one another and grow in multiple layers, forming a tumor. Cancer cells keep on dividing, even when stimulatory growth factors are absent, and they do not respond to inhibitory growth factors.

The statement "Cancer cells show no contact inhibition. Therefore, cell growth and division do not stop" is true.

Cancer cells are abnormal cells that grow rapidly without stopping. These cells cause tumors because of unstoppable cell growth.

The amount of times that cancer cells can divide is infinite because they are immortal. A tumor is created when cancer cells stack on top of one another and grow in numerous layers.

Even in the absence of stimulator growth factors, cancer cells continue to divide and do not react to inhibitory growth factors. No contact inhibition is a mechanism that is used for stropping cancer and this inhibition is not present in cancer cells, that's why they divide rapidly.

Therefore, the statement is true.

Answer:

cells come from cells

Explanation:

The component of cell theories is that all cells come from already existing cells by division.

The component of the cell is that it is the primary element of life and that all the living things are made of one or more cells.

New cells come from the old ones by division and it means that no living thing can come into being through the non-living thing.
