No organism is always the first step, except in a wide sense, plants. In the water, plankton is found in first but whereas on land, plants or seeds are eaten first.
Hope it helped!! :)
Futile resistance is the immunity system and HIV infections. HIV infection results in immunodeficiency because it acts as infects helper of T cells and its reception is CD4. Again immunodeficiency is a helper of T cells which are destroyed and the host can’t develop an immune response.
We have primary immunodeficiency which is a developmental and genetic defect in immunity. Secondary immunodeficiency results from damage to immune cells after developing normally. For example cancer, leukaemia and HIV. Effect of immunodeficiency appears sick all the time.
The complete question is :
Algae are plantlike organisms that live in the water. These algae have been in sunlight for several hours now. What can the algae do because they are in sunlight? What does this mean for the number of energy storage molecules in the algae?The algae can . . .
take in carbon from the air. The carbon is used to make energy storage molecules.
take in carbon from the air. The carbon is used to break down energy storage molecules.
give off carbon to the air. Giving off carbon allows them to make energy storage molecules.
give off carbon to the air. Giving off carbon uses up energy storage molecules.
Answer: Option A
Explanation:
Algae are plant like organism found in water, they are capable of performing photosynthesis.
Th algae in water trap carbon dioxide from the atmosphere( water) in order to convert into energy molecules known as glucose in the presence of sunlight.
This means the number of energy storage molecules in the algae increases after photosynthesis.
This is how the algae uses sunlight in order to prepare glucose from them.
One major difference between viruses and other cells is that viral particles have nucleic acid located within a capsid.
<h3>Structure of a virus</h3>
Viruses are made up essentially of ribonucleic or deoxyribonucleic acids enclosed in a proteinous shell known as capsids.
This is unlike other cells in which their nucleic acids either lie freely within the cytoplasm of their cells or are enclosed in a double membrane structure known as the nucleus.
Viruses are essentially non-living when outside a living host.
