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.

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.

can natural selection happen in the hardy-weinberg equilibrum
Answer:
yes
Explanation:
The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow. ... Because all of these disruptive forces commonly occur in nature, the Hardy-Weinberg equilibrium rarely applies in reality.

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.

Answer:
Present at nucleus and cytoplasm
Answer:
Characteristic feature of RNA are as follow:
Ribonucleic acid“ RNA” is another nucleic acid type. Like deoxyribonucleic acid “DNA ” it is polynucleotide but several differences are found in their structure.
In RNA the pentose sugar is ribose not deoxyribose.
RNA contain uracil in place of thymine.

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 best describes the importance of mitosis to living organisms
Answer:
Mitosis is a process of cell division that leads into formation of two daughter cells that are genetically identical to each other and to the original cell. So this is greatly important to living organisms because Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.

Thousands of years ago, the jaws and teeth of jaguars were more varied in size than they are today. During a period of climate change about 11,000 years ago, jaguars faced a
shortage of food. There were fewer mammals to eat, so the jaguars had to eat shelled reptiles. The jaguars with the largest jaws and teeth could most easily eat the shelled reptiles.
Which of the following statements best explains why large jaws and teeth are common characteristics in jaguars today?
O A. Jaguars with the smallest jaws and teeth died out completely.
B. Jaguars with the smallest jaws and teeth were not ever able to mate.
O C. Jaguars with the largest jaws and teeth survived and reproduced more successfully than other jaguars.
D. Jaguars with the largest jaws and teeth strengthened them by using them more frequently than other jaguars.
Larger jaws and teeth helped certain jaguars survive and procreate more successfully than others. It is an example of natural selection. Therefore, option C is correct.
What is natural selection?Natural selection is the process through which populations of living things adapt and change. According to this, nature chooses the creatures that can adapt to changing environmental conditions and reproduce while eradicating those that cannot.
Natural selection, according to Darwin, is a lengthy, complex process involving several interconnected factors. Natural selection requires variation among the organisms in a population. For the process to work, it must be heritable and passed in some way to the organism's offspring.
Thus, Jaguars with the largest jaws and teeth survived and reproduced more successfully than other jaguars. It is an example of natural selection. Therefore, option C is correct.
