What are levels of organization in multicellular organisms?

Answers

Answer 1

Answer: The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system.
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.

How does your body stop viral infections? What are ways of protection against viral infection?

Answers

A division of your immune system called cell mediated immunity is charged with stopping viral infections. The main actors of that are called cytotoxic T cells who, when they encounter a cell that is displaying viral antigens on its surface, binds to the cell and releases toxic substances called perforins and granzymes that destroy and digest the viral infected cell.

I think its because the white blood cells stops the infections before it can infect the body I don't really know

Hello!

For background the plant shown is an orchid. Generally, purple is the dominant color and trait within this species and white the recessive allele.

If we use Mendell's Punnett Square we can actually see that together the pair are codominant with one another.

So the answer to your question would be, c. codominant with the allele for the white flower color.

If only one particular color was showing, we could say that one was dominant over the other. However, due to the fact that both traits show, that means they are codominant ! As recessive genes will not show under the presence of a dominant gene.

Hope this helps answer your question!

How do viruses differ from bacteria, fungi, and parasites?

Answers

Virues are different from bacteria, fungi and parasites, beacuse they can not survive without the presence of a host organism.They need a host to reside into, replicate, obtain nutrition and thrive. Outside host, they are just present as proteins or capsids.

Parasites are a piece of a vast gathering of living beings called eukaryotes. Parasites are not the same as viruses or bacteria infections on the grounds that their cells share many components with human cells including a characterized core. A few parasites just imitate inside a host living being, however, some can increase openly in the earth.

Nitrogen is an important element in ____________ compound such as __________, DNA, ______________________ & chlorophyll. Nitrogen is the most _________________ gas in the atmosphere. It cycles from the _________________ to ______________ ____________ & back to __________________. But living things cannot use it in its gas form, therefore living things get ________________ from the __________. 1. Living organisms cannot use simple nitrogen molecules (NH2). 2. Living things take it in as a nitrate (NO3-). 3. Nitrate is formed when nitrogen is combined with oxygen. This process is called nitrogen ____________________.

Answers

Answer:

Nitrogen is an important element in the living things.

Compounds such as amino acids, DNA, proteins and DNA

Nitrogen is the most Abu can't gas in the atmosphere. It cycles from the atmosphere,to the terrestrial habitat and Marine habitat then back to the atmosphere.

Living things nitrogen from the nitrogenous compound.

Nitrate is formed when nitrogen combine with oxygen and it is called nitrogen fixation.

Explanation:

Nitrogen is an important element in living things and it is important for life processes. It is the major constituent of DNA, protein, amino acids and Chlorophyii.

Nitrogen is released from the atmosphere to the root nodules of leguminous plants or to the soil by bacteria called nitrogen fixing bacteria . Nitrogen can not be absorb in gaseous form by plants because they are unreactive but they are converted to nitrates and ammonium compound.
