Answer:
The amount of matter in a system stays constant, it is not created nor destroyed.
Explanation:
For example, in a situation such as a chemical reaction, the atoms of the molecules never magically appear or vanish. The atoms of the reactants are simply rearranged into a product. Hope this helps.

In essence, DNA is a thin and very, very long organic molecule. It is a polymer, and each of the monomers that constitute it are called ______
Answer:
nucleotides
Explanation:
DNAs are long-chain, helical macromolecules that store genetic information They are made up of varying sequences of covalently bonded monomers called nucleotides. Four types of nucleotides make up the nucleic acid DNA, these include Adenine, Guanine, Cytosine and Thymine.
Unlike other macromolecules, these are typically not used as an energy source and only encode protein synthesis. They comprise a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.
Nitrogenous bases encourage base-pair formation through hydrogen bonding. Adenine forms double bonds with thymine, while cytosine forms triple bonds with guanine.

Answer:
C The correct sequence of the transfer of information in most organisms is DNA to RNA to protein.
Explanation:
Gene expression involves the flow of information from DNA molecules to the formation of proteins. Information first flows from DNA molecules to RNA through a process called transcription. Transcription is the first step of gene expression in which an RNA especially the mRNA is synthesized from a DNA molecule by RNA polymerase enzyme. Then the synthesized mRNA is taken to the cytoplasm where it undergoes the translation process to form proteins.
how would you describe cellular respiration to a younger child?
Answer:
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy.
Explanation:
Usually, this process uses oxygen, and is called aerobic respiration.

1. If you flipped two coins simultaneously, for a total of 8 times, how many times, on average, would you expect to get two tails?
2. What was the percent deviation of tails when 10000 observations were made?
3. What was the percent deviation for tails when the coin was tossed 10 times? To get the percent deviation for tails, take the number you recorded for deviation, multiply by 100, and divide by the "expected results"
4. In the 10000 coin flips, you completed the "expected" column, and a value was given for the "observed results" column. What was the deviation for heads?

Can organisms plan and willingly change their
mutations in their genes? Why or why not.
simple answer 1 sentence please
Answer:
No
Explanation:
Organisms cannot willingly change their mutations as these things occur by chance and within the genetic code which the organisms have no direct power over.
Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.
Answer:
Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.

Duchenne Muscular Dystrophy (DMD) is an X-linked recessive trait that causes muscular weakness, deterioration of muscle tissue, and loss of coordination. The allele for DMD is represented by Xd and the normal allele is represented by XD . Neither parent has DMD, but both of their sons express the trait. What are the genotypes of the parents?
Answer:
The correct answer is - XDXd and XD Y
Explanation:
Sex-linked disorders are the disorders that are expressed only when there is two copy of the mutated allele or have not masked by the dominant allele of the gene. In DMD, the dominant allele is XD and the mutated allele is Xd. To express it there are the following genotype possible-
in women XdXd, and in men XdY, so these two genotypes are not possible for the parents in this case. If a mutated allele is present with the dominant allele it will be considered as carrier women but diseased will not be found in them.
So the correct genotype would be
mother: XDXd ( a carrier woman)
father : XDY (normal man)

Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind
Answer:
Where the primate infant did not possess primate hand features, it will not be able to feed itself. For example, a monkey cannot survive without its grasping hands. It uses them to feed itself. So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.
Explanation:
Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet. Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans. Human beings feature deep perceptions that differentiate them from other primates.
Question 4 of 5 Which phrase best describes an individual organ? O A. Made of one kind of cell B. The simplest unit of life O C. Meets all the needs of an organism O D. Made of different kinds of tissues
The answer is D it's made of different kinds of tissues,due to the fact most animals and plants have organs,which are self-contained groups of tissues(more than one) such as the heart that work together to perform one function.

The function of oxygen in aerobic respiration is to:
a) carry hydrogen ions from the Krebs cycle to the electron transport chain
b) bind electrons and hydrogen ions at the end of the electron transport chain
c) attach a high energy phosphate group to ADP
d) form carbon dioxide in the Krebs cycle
e) donate electrons to NADH to make it release a hydrogen ion
Answer:
Aerobic respiration uses oxygen to break down glucose, amino acids, and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles.

A small, leafy branch is cut from a tree. After some hours, the stem of the branch remains firm . Suggest an explanation for this
Answer:
Explanation:
When a branch is detached from a tree, water is being lost through the porous open area. After some time, a callous formation of new tissues starts to appear on the open surface to terminate further loss of water. The osmotic pressure in the leaves gets reduced as they no longer contain enough water, while the stem is being filled with water due to the network of capillaries.
