The sides or backbone of DNA is made up of what two molecules? (green in the diagram below)
Multiple choice answers
-Sugar-Nitrogen Base
-Sugar-Phosphate
-Phosphate-Nitrogen Base
-All sugar molecules
Answer: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

Distinguish between Diet and Nutrition
Answer:
Diet is limiting oneself in foods and calories for several days or weeks. As a result, overweight is rapidly leaving, but once you return to your previous lifestyle, as extra pounds return, and getting rid of them becomes more difficult.
Proper nutrition is a complete balanced everyday diet, in which all necessary products must be present: meat, cereals, dairy products, fruits, vegetables. Eating healthy and balanced all the time not only strengthens the body but also helps to lose weight. It is known that an organism that does not regularly receive all the necessary substances begins to "junk".

please mark as brainliest ..... thank you!
[tex]\huge{\mathbb{\tt { What \: is \: Diet?}}}[/tex]
In nutrition, diet is the sum of food consumed by a person or other organism. The word diet often implies the use of specific intake of nutrition for health or weight-management reasons. Although humans are omnivores, each culture and each person holds some food preferences or some food taboos.[tex]\huge{\mathbb{\tt { What \: is \: Nutrition?}}}[/tex]
Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.[tex]{\boxed{\boxed{\tt { Difference \: between \: Diet \: and \: Nutrition}}}}[/tex]
The main way of getting nutrition is by having a proper diet. Diet comprises of different foods, which contain nutrients. When the foods are ingested, nutrients are absorbed by the body. Body uses them in different metabolic activities. A poor diet will result in a poor metabolic efficiency. Finally, it may lead to nutrient disorders or unbalance nutritional conditions in human body.#CarryOnLearning

Write a poem about symbiotic relationships. It must include Commensalism Mutualism, Parasitism, Competition, and Predation.
Answer:
Explanation about Commensalism Mutualism, Parasitism, Competition, and Predation are given below.
Explanation:
There are various symbiotic relationship formed between the organisms present in the environment. These relationships are Commensalism Mutualism, Parasitism, Competition, and Predation. In Commensalism relationship, one organisms gets benefits while the other neither get benefit nor harm. In mutualism, both organisms gets benefits from one another. In Parasitism, one organism get benefits and the other get harmed. In Competition, both organisms cause harm to one another and both are damaged through their actions and in Predation, one organism is benefited by killing the other organism to feed itself.

The image depicts the impact of a mutagen on the phenotype of F1 and F2 offspring in nematodes, a common roundworm. Which
arguments can be made based on the information in the model You may select more than one correct choice.
Answer:
A, D, E
Explanation:
just did it
The arguments that can be made based on the information in the model are as follows:
The mutated DNA is a recessive allele. The mutagen altered the DNA of the worm in the parental generation. The DNA altered by the mutagen occurs in gamete cells and is passed to offspring.Thus, the correct options for this question are A, D, and E.
What is Mutagen?Mutagen may be characterized as a type of agent that possesses the capability to induce mutation within the genetic segment of living organisms. Mutagens are of two types, they are:
Physical mutagens: UV radiations.Chemical mutagens: Chemicals like ethidium bromide.According to the context of this question, mutation can only be inherited from parent to offspring, if it is induced within the gamete cells of parents. While during the course of life, the mutation also induces in the genomic sequence of an individual.
Therefore, the correct options for this question are A, D, and E.

HELP MEE
Its about bio and its confusing
Answer:
a) the process of mitosis generates new cells that are genetically identical to each other. mitosis helps organisms grow in size and repair damaged tissue. some species of alge are capable of growing very quickly.
b) more growth occurs in the root tips and very little new cell development occurs in woody stems after they are formed
c) sequential order means put things in order.
A B C D E
Hello again, Bakere!
a) Mitosis, the dividing of a single cell into two daughter cells, is a way for the plant to stay healthy-looking and strong. All cells die eventually, and they must be replaced by new, fresh ones. This replacement occurs through mitosis. Mitosis also allows the plant to grow, as mitosis is found more frequently in growing areas than ones that are finished growing. Since mitosis makes more cells, you will find much more mitosis occurring in a new shoot than in an old tree, because the old tree doesn't need a bunch of new cells to continue growing.
b) Mitosis is more frequent on the outside of the root because new cells are needed constantly as multitudes of them are scrubbed away by rough dirt. On the inside of the root, however, there is little to no exposure to harsh soil erosion. Because of this, mitosis is needed less here - only to replace the dying cells.
c) The order for the letters should be: A, E, D, B, C. I'm including a picture to help you understand why. :)
