Where did the water cycle begin?
Answer:
The water cycle has no starting point. But, we'll begin in the oceans, since that is where most of Earth's water exists.

Nucleotides are monomers composed of DNA, a nucleic acid that serves as a storage molecule to encode proteins, along with RNA, a ribose sugar-containing nucleotide. In nucleotides, 5-carbon deoxyribose or ribose sugar, phosphate and one of four bases of nitrogen are found:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).

Answer:
The heart consists of four chambers organized into two pumps (right and left) for the purpose of providing blood flow to the systemic and pulmonary circulations. The right atrium receives deoxygenated blood from the entire body except for the lungs via the superior and inferior vena cavae!
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.
Hope this helps!

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand.
True
False
Answer:
true
Explanation:
please mark me brainliest
DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.
What is DNA replication?The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.
In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.
Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

Explanation:
If hydrogen peroxide is stored in a clear glass bottle and is left to stand, it decomposes into water and oxygen.Which of the following correctly shows the balanced equation for this decomposition?
1. 2HO2-------------> 2HO + O
2. 2H2O2--------------> 2H2O + O2
3. 2H2O-----------------> 2H2O + O2
4. H2O2----------------> H2O + O
Help pls
Answer:
2. 2H2O2 -> 2H2O+ O2
Explanation:
This equation is balanced because there are equal amounts of each element on each side. 4 Hydrogen on the left, 4 On the Right. 4 Oxygen on the Left, 4 on the right.
Although 1 is balanced it is not the Chemical equation for hydrogen peroxide (H2O2)
2. is not the equation for Hydrogen Peroxide
4. Balanced although this one does not show oxygen as a gas ( when oxygen is a gas it is O2)

How do guard cells maintain homeostasis?
Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.

Many of the sun's rays may be PARTIALLY blocked by dust or clouds
formed by volcanic eruptions or pollution. What are some possible short-
term effects of this on photosynthesis?
Photosynthesis will happen faster/more
Phstosynthesis will happen slower/less
Photosynthesis will NOT happen at all
Nothing will change
Answer:
B. Photosynthesis will happen slower/less
Explanation:
Option B is the possible short-term effect on photosynthesis when the sun's rays are partially blocked.
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide. When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Photosynthesis makes use of sunlight. But if sunlight is partially blocked, the process by which photosynthesis occurs becomes slow or less. This is because as the sunlight is partially blocked, there is no adequate supply of sunlight to carry out photosynthesis.

Answer:
The three lines of defense represent an approach to providing structure around risk management and internal controls within an organization by defining roles and responsibilities in different areas and the relationship between those different areas.
in mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.
True. In mammals, an increase in the temperature of the preoptic area of the hypothalamus activates physiological mechanisms for heat dissipation including vasodilation.
What is vasodilation?Vasodilation, as it is known in medicine, occurs when blood vessels in your body open up, enabling more blood to flow through them and resulting in a reduction in blood pressure. Without your knowledge, your body goes through a routine procedure like this. It can also be brought on by the foods and beverages you consume as well as the drugs you take. Vasodilation may also be a sign of a particular illness.
The two of the many functions that your blood serves in the body:
Carrying oxygen and nutrients Aiding in temperature regulation in your body.Your body's blood arteries are more complex than simple tubes that remain constant in size. Your blood arteries include muscle as well, and that muscle regulates how wide or narrow they are at any particular time. Vasodilation occurs when blood vessels enlarge. Vasoconstriction is the opposite process, which occurs when blood vessels narrow and contract.

Based on the identification of T-cell receptor B variable gene segments in genomic DNA an estimation of the size of the human T-cell receptor B variable gene segment repertoire was embarked upon.
PCR amplification from uncloned and cloned genomic DNA sources, Southern blot hybridization, nucleotide sequencing, and cosmid cloning were used to identify T-cell receptor B variable gene segments in numerous irrelevant individuals. The benefits of this strategy lead to many findings such as there was a possibility of discriminating between alleles at the products of different loci and the same locus, T-cell receptor B variable gene segments c expressed at very low levels in libraries of Complementary DNA are detectable. 63 unique T-cell receptor B variable gene segments were sequenced and identified .Out of 63 , 51 contained Thirty-four cosmid clones which were isolated and later filtered for the existence of further T-cell receptor B variable subfamily members.The results were that human T-cell receptor B variable germline repertoire encodes at least 63 T-cell receptor B variable gene segments out of which 52 are functional.
