We use Chargaff's rule to get the answer.
[A] + [G] = [C]+ [T].
[A] + [G] + [C] + [T] = 100%
Where is A is Adenine, G is Gaunine, T is Thymine and C is Cytosine.
In DNA, Adenine always pairs with Thymine, and Guanine always pairs with Cytosine.
Therefore if Thymine is 35%, then Adenine will also be 35% to make 70% in total.
The remaining percentage will be 100% - 70% = 30%.
The 30% will be shared equally among Cytosine and Guanine, at 15% each. Therefore Cytosine will be 15%
Answer: Mosses retain soil humidity and prevents its degradation, besides are habitat for little invertebrates.
Explanation: Mosses are non-vascular plants (they don't have conductive vessels as xylem and phloem) that live places as tree trunks, rocks, walls and soils. This habitats must be humids because mosses need water for nutrient transport, because they don't have cuticle (prevents water lost) and for fertilization. Mosses are important for the ecosistems where they live because retain water in the soils thus prevent erosion and harbor invertebrates as Tardigrades (water bears).
Answer:
the answer would be the 3rd answer

Answer:
Food refers to any nutritious substance whereas diet refers to the food eaten by organisms daily.
2,110 calories.
Explanation:
1. Food refers to any nutritious substance that an organisms eat in order to survive and maintain growth whereas diet refers to the sum of food that is consumed by an organism.
2. Malnutrition refers to a condition that occurs from eating a diet which does not supply a healthy amount of nutrients to our body whereas hunger refers to a feeling of discomfort that is caused by lack of food.
3. No, it is not possible to be over-nourished and under-nourished at the same time because a person can attain one condition at a time whether he can be over-nourished or under-nourished.
4. The three elements of food security are availability, access and consumption of food. Availability of food means having sufficient quantities of nutritive food available to a person, access means having sufficient resources to have access to the food and consumption means having taking sufficient amount of nutrients and the ability to absorb and use nutrients in the body.
5. 2,110 calories are taken by consuming 345g of carbohydrate, 80 g of protein, 45g of fat and 12g of alcohol.
<span>Blood provides an ideal opportunity for the study of human variation without cultural prejudice. It can be easily classified for many different genetically inherited blood typing systems. Also significant is the fact that we rarely take blood types into consideration in selecting mates. In addition, few people know their own type today and no one did prior to 1900. As a result, differences in blood type frequencies around the world are most likely due to other factors than social discrimination. Contemporary Japan is somewhat of an exception since there are popular Japanese stereotypes about people with different blood types. This could affect choice in marriage partners for some Japanese. </span>All human populations share the same 29 known blood systems, although they differ in the frequencies of specific types. Given the evolutionary closeness of apes and monkeys to our species, it is not surprising that some of them share a number of blood typing systems with us as well. When we donate blood or have surgery, a small sample is usually taken in advance for at least ABO and Rh systems typing. If you are O+, the O is your ABO type and the + is your Rh type. It is possible to be A, B, AB, or O as well as Rh+ or Rh- You inherited your blood types from your parents and the environment in which you live cannot change them.
