Protists represent an important evolutionary step between single-celled organisms and multi-celled organisms.
Protists have similar DNA to the DNA of cyanobacteria. This similarity show the evolutionary relationship between cyanobacteria and algae in which cyanobacteria is a single celled organism whereas algae is multi-celled organism so from this discussion we can conclude that protists is an important evolutionary step between single celled organism and multi-celled organism.

give two examples of what a living thing can do once it has converted the energy from food into usable forms of energy.
Answer:
When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.
Two examples of what a living thing can do once it has converted the energy from food into usable forms of energy are growth, reproduction, and movement, and by using the energy, they survive in the ecosystem.
What is the significance of the energy from food?Energy from food can be obtained, and that energy is further used for many reasons, such as metabolism and movement, and a living organism can use it to power its muscles for movement such as running and swimming. Apart from that, the energy is used for growth and reproduction, which allow an organism to develop and produce offspring.
Hence, two examples of what a living thing can do once it has converted the energy from food into usable forms of energy are growth, reproduction, and movement, and by using the energy, they survive in the ecosystem.

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes
Answer:
Chromosomes form is DNA in during mitosis.
Explanation:
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.
During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.

a group of plant cells was exposed to radiation, which damaged the chloroplasts and coursed them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cell
Explanation:
First of all the mitochondria is the power house of a cell. Then a chloroplast is one which contains chlorophyll in which photosynthesis takes place.
Plants make use of photosynthesis to synthesize nutrients from carbon dioxide and water. If the chloroplast is damaged that means the plant would wither but it may not likely die since the mitochondria is unharmed.

HIV binds to Helper T cells of your immune system.
A. True
B. False
Answer: True
HIV infects a type of white blood cell in the body's immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases. HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together).
Explanation:
T-cells, the thymus cells, work in a similar way but destroy infected cells rather than manufacture antibodies. In HIV infection, the body mounts a very strong antibody response in the first few weeks that partially works, bringing the viral load down from millions to, on average, about 50,000 copies/ml.
Answer:
The answer is true...
Explanation:
HIV infects a type of white blood cell in the body’s immune system called a T-helper cell (also called a CD4 cell). These vital cells keep us healthy by fighting off infections and diseases.
HIV cannot reproduce on its own. Instead, the virus attaches itself to a T-helper cell and fuses with it (joins together). It then takes control of the cell’s DNA, makes copies of itself inside the cell, and finally releases more HIV into the blood. HIV will continue to multiply and spread throughout the body – a process called the HIV lifecycle.
In this way, HIV weakens the body’s natural defences and over time severely damages the immune system. How quickly the virus develops depends on a person’s general health, how quickly they are diagnosed and start antiretroviral treatment, and how consistently they take their treatment
Give any 2 significance of nitrogen cycle to green plant
Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is made up of nitrogen gas (N2).
Plant uptake of nitrogen compounds
Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
As part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.
Fixation
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

Which type of succession does this describe?
secondary
primary
island
aquatic
Answer:
The correct answer is primary succession.
Explanation:
The development of an ecosystem in a region where no form or sign of life existed before is termed as primary succession. In the mentioned case, a glacier at the start did not support any form of life, however, it started producing a mountain lake where some form of life started to appear gradually. With time, the development of the pioneer community will take place, which will eventually get transformed into a climax community.
In comparison, a kind of succession that takes place in the regions where life prevailed before but got destroyed or eliminated due to natural disasters or human applications is termed secondary succession.
