Answer: microscope
Explanation:
erwin chargaff discovered that the dna of any species contains equal amounts of adenine and thymine, and also equal amounts of cytosine and guanine
based on this information, scientists could predict that the base
pairs with
and the base
pairs with
in the information of the adn molecule
Answer:
The base adenine pairs with thymine, and the base cytosine pairs with guanine.
Explanation:
From Chargaff's discovery, which was that the DNA of any given species contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine, we can deduce that if there is an equal amount of two bases in DNA, those two bases must pair together. From this information, we can then go on to say that since there are equal amounts of adenine and thymine, they pair together, and since there are equal amounts of cytosine and guanine, they also pair together.

How is harvesting food crops similar to, and different from, mining?
Answer:
Both extract from the soil while difference in their extraction method.
Explanation:
Harvesting food crops similar to mining because both are gained from the soil whereas it is also different from mining due to their method of extraction. Seeds are grown again and again in the soil and other agronomic activities has to be done to gain good yield of the crops while on the other hand, in mining precious metals is to be extracted that is already present in the soil.

difference between structure and function. ( who ever writes the most gets brainliest AND NO PLAGIARISM.
Explanation:
if you were trying to find the function of something it you would mainly think of roles, jobs, responsibilities, chores etc, where as if you were trying to find the structure it would be how something is made up or its form.
for example the srtucture of a plant, meaning its form or how it grew, its function depends on what type of plant, if it were just a regular plant or leaf, the stomata, cell wall, cell membrane, nucleus, chloroplasts, chlorophyll inside the chloroplasts, mitochondria, cytoplasm, would be requied to do their funtions i.e their jobs to keep the plant/leaf alive

Water is essential to all living things. (a) Identify THREE properties of water. (b) Describe the property of water responsible for any ONE of the following statements. You are only choosing to discuss one of these four statements. (1): The role of water as a medium for the metabolic processes of cells (2) The ability of water to control temperature within living organisms and in the environment (3) The movement of water from the roots to the leaves of plants (4) The ability of other molecules to dissolve in water
Answer:
gas, solid, liquid
Explanation:
Answer:
(A) The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
(B) (1) Water is the medium for various enzymatic & chemical reactions in the body.
(B) (2) Waters high specific heat enables it to act as an absorber of heat inside an organisms body. -
(B) (3) Transpiration is the loss of water from a plant in the form of water vapor.
(B) (4)Because of its polarity and ability to form hydrogen bonds, water makes an excellent solvent, meaning that it can dissolve many different kinds of molecules.
Explanation:
(A) A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.
(B) (1) It moves nutrients, hormones, antibodies and oxygen through the blood stream and lymphatic system. The proteins and enzymes in our body function more efficiently in solutions of low viscosity.
(B) (2) Waters high heat of vaporization allows the body to cool by perspiring. When the water evaporates off the skin a lot of heat is absorbed. Explain the movement of water from the roots to the leaves of plants.
(B) (3) Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor.
