Explanation:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

What are three ways a plant's organ systems work together?
A The shoot system delivers food to the root system.
B. The root system delivers materials from the soil to the shoot
system
The ground tissue of the root system protects the vascular tissue
in roots
D. The ground tissue of the root system stores food for later use by
leaves
Answer: A, B, D
Explanation: credit to the comments on the other. I also did the test
The three ways through which a plant's organ systems work together are as follows:
The shoot system delivers food to the root system.The root system delivers materials from the soil to the shoot system. The ground tissue of the root system stores food for later use by leaves.Thus, the correct options are A, B, and D.
How do plants deliver water and nutrients to other parts?Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.
Xylem transports water, nutrients, and other minerals from the soil to all parts.
Phloem mediates the migration of foods from the leaves to the rest of the plants.
The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.
The ground tissue of the vascular plant is responsible for storing the carbohydrates constructed by the plants and utilized by the leaves when required.
Therefore, the correct options are A, B, and D.

Choose all of the areas in which the United States invoked the Roosevelt Corollary to the Monroe Doctrine.
The correct answer to this open question is the following.
Unfortunately, you did not attach the options to answer this question.
What we can do to help you is commenting on the following.
Throughout history, the United States invoked the Roosevelt Corollary to the Monroe Doctrine to accomplish some imperialistic and interventionists goals in different Central American and South American countries.
We can set some examples here. For instance, that was the case of the US intervention in the Island of Cuba, in Nicaragua, Dominican Republic, Hati, and the US presence for so many years in the Panama Canal.
Let's have in mind that the Roosevelt Corollary to the Monroe Doctrine was originally called for intervening in Latin American countries that could not pay their debt to European creditors.
The message the US wanted to convey to European superpowers that had interests in this region was that from now on, it was going to be the US business to intervene in the Americas. If Europe tried to intervene, it was going to be understood as direct aggression to the United States.

Experiments on Osmosis are often carried out using potato
cylinders. You have been asked to find out if sweet potato or bread
fruit would be a good alternative
The osmosis process is based on solute concentration, if sweet potato or breadfruit has more amount of sucrose changing the osmolarity, hence not used for osmosis.
What is osmosis?When a potato is placed in salt water, all the water inside it, plants have a lot of water inside them, that's what gives a plant its structure travels out by osmosis because water will move from an area of less salt to more salt (more water to less water).
The cells that makeup potatoes have cell walls that function as semipermeable membranes. In comparison to the fluid inside the potato cells, the saltwater solution is hypotonic, meaning that it has more water and fewer salts.
This is because a sweet potato has more sugar than a regular potato, changing the osmolarity conditions during osmosis.
Therefore osmolarity condition is more important during osmosis, hence sweet potato or breadfruit would not be a good alternative.

Answer:
The correct answer is:
planters (D)
Explanation:
The key statement in the question is that Andrew wants to apply pesticides and fertilizers to all his crops across his large land. The most effective way of doing this is by using a planter to apply both the fertilizer and the pesticide as the planting occurs. This will ensure that the fertilizers and pesticides are applied directly to the crops and not scattered on the vast land.
What is the structure of DNA? 20 points.
Answer:
Basic structure of DNA
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
DNA structure and function
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
Explanation:
DNA is made up of molecules called nucleotides. Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, while the bases would be the rungs.
