Deoxyribonucleic acid is a kind of DNA. DNA is a polymer made up of two polynucleotide chains that coil around one another to create a double helix. (listen);[1] DNA) All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).
Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

Answer:
In a species of beetles, males that have large horns are better able to fight off other males for access to females. This is an example of intrasexual selection.
Explanation:
Intrasexual selection can refer to the act of competing with members of one's own sex (for status, tangible resources, or directly for access to mates) as well as the evolutionary process that shapes the traits employed in this competition.

Answer: In the plant light energy is converted to chemical energy
Explain how plants respond to a light source, usually the Sun. What is occurring inside the plant, and what hormone is involved?
Answer:
Plants also exhibit phototropism, or growing toward a light source. This response is controlled by a plant growth hormone called auxin. As shown in Figure below, auxin stimulate s cell s on the dark side of a plant to grow longer. This causes the plant to bend toward the light.
Explanation:
How do we obtain energy from plants?
To obtain energy from plants, we must intake the plant items and the sugars of the plants are broken down into further smaller components inside the human body by the process of respiration to gain energy.
Energy is the amongst the most essential requirement of the living body to carry out the various processes of life. Energy may have different chemical form in different organisms but the most prevalent form of energy used is ATP.

d. binary fission; the injury would trigger cell division to replace those cells; results in 2 identical cells
Answer:
a. mitosis; the injury would trigger cell division to replace those cells ; results in 2 identical cells
Explanation:
Mitosis is the cell-creation process that an animal would undergo while healing a cut. It is a division that results in two daughter cells. The answer is not binary fission as that is an asexual reproductive method that occurs most often in simple, single-celled organisms like bacteria. It would not be used in the body during the process of healing a cut. The answer is not that it results in 4 identical cells, as mitosis (which is the process used in healing a cut) can only result in 2 identical daughter cells, not four. 4 resulting cells is characteristic of meiosis, which differs from mitosis as each of the 4 daughter cells created in this process are genetically unique and only contain half as much DNA as the parent cell. With these understandings in mind, you can rule out all options other than A.

which of the following a change related to the aging of the respiratory system? group of answer choices
An increase in respiration rate is a change related to the aging of the respiratory system.
What is respiration?Respiration is defined in physiology as the transfer of oxygen from the external environment to the cells within tissues and the removal of carbon dioxide in the opposite direction, that is, back into the external environment. The biochemical definition of respiration, which refers to a metabolic process through which an organism obtains energy (in the form of ATP and NADPH) by oxidizing nutrients and releasing waste products, differs from the physiological definition. Although cellular respiration and the subsequent maintenance of life in animals depend on physiologic respiration, the two processes are distinct: cellular respiration occurs within individual organism cells, whereas physiologic respiration deals with the diffusion and transport of metabolites between the organism and the external environment.
What is respiratory system?The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

What is coral bleaching and what causes coral bleaching?
Corals will eject the algae (zooxanthellae) dwelling in their tissues if the water is too warm, which will turn the coral entirely white. The term for this is coral bleaching.
What is coral bleaching?
Corals release the microscopic algae that reside in their tissues when they are under stress. Coral tissues become transparent in the absence of these algae, revealing their white skeleton. The term for this is coral bleaching. While bleached corals are not actually dead, they are more vulnerable to famine and illness.Why do coral reefs bleach?
When corals are under stress, bleaching happens. Summer heat stress brought on by hotter water and more UV rays is a major factor in coral bleaching on the Great Barrier Reef. Bleaching can be caused by a temperature increase of merely one degree Celsius for four weeks.Corals start to hunger when their food source—the zooxanthellae—is taken away. Corals start to perish if elevated water temperatures remain for a long time (eight weeks or more).Hence, UV radiations are the major cause for coral bleaching.

1.The nitrogen cycle starts with plants.
2.The nitrogen cycle has no beginning or end.
3.The nitrogen cycle ends with animals.
Answer:

Explanation:
How does the nitrogen cycle work? Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. Step 2- Nitrification- Nitrification is the process that converts the ammonia into nitrite ions which the plants can take in as nutrients.
So even when starting with the first question we know that nitrogen is present in soil BUT the cycle begins during Nitrogen Fixation which plants use.
we also know that the nitrogen cycle has a start-- given I just explained that-- and even though it's continuous there is a point where the cycle repeats and therefore starts again. Knowing it's continuous we also know that when nitrogen 'ends' the cycle simply starts again, and the nitrogen is released back into the air. ("Nitrogen gas [N2] diffuses into the soil from the atmosphere")
