The circulatory system works with the respiratory system to circulate blood and oxygen throughout the body.
The cardiovascular system (also called the circulatory system) transports blood from the heart to the lungs, where it is oxygenated. After receiving oxygen, blood is pumped out of the heart and into the body's arteries. Veins return blood that is low on oxygen to the heart, where the pumping process can begin again. Your body's organs, muscles, and tissues can't function properly without a strong circulatory system. The job of the circulatory system is to transport blood all over the body. The body's organs, muscles, and tissues would not function to keep you alive if the blood didn't circulate through them.
Getting rid of waste is another function of the circulatory system. Examples of such trash are:
Oxygen used in respiration produces carbon dioxide.
Excretions and waste products from your body's systems.
Food and drink scraps are waste products.

What is the net ATP produced during glycolysis ?
Both anaerobic and aerobic conditions can result in glycolysis. Pyruvate enters the citric acid cycle under aerobic conditions and undergoes oxidative phosphorylation, producing a net of 32 ATP molecules.
In the end, glycolysis divides glucose into two pyruvate molecules. Glycolysis can be thought of as having two stages that take place in the cytosol of cells. Due to the use of two ATP molecules, the first phase is known as the "investment" phase, while the second is known as the "payoff" phase. Each of these processes is performed by a different enzyme, with phosphofructokinase serving as the most crucial regulator because it regulates the rate of glycolysis.
Aerobic and anaerobic conditions both result in glycolysis. Pyruvate enters the citric acid cycle and goes through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules under aerobic conditions. Pyruvate is transformed to lactate in anaerobic environments by anaerobic glycolysis. Two ATP molecules are produced during anaerobic respiration. Cell cytosol is the location of glycolysis.

Write a claim evidence and reasoning on Do trees change the composition of the atmosphere around us?
Answer:
Evidence: Trees absorb carbon dioxide from the atmosphere during the process of photosynthesis, and release oxygen as a byproduct. In this way, trees play a vital role in the global carbon cycle, and can help to mitigate the negative impacts of human activities that contribute to the increase of atmospheric carbon dioxide, such as the burning of fossil fuels.
Reasoning: The evidence provided demonstrates that trees have a direct effect on the composition of the atmosphere through their role in the carbon cycle. By absorbing carbon dioxide and releasing oxygen, trees can help to balance the levels of these gases in the atmosphere, and contribute to the overall health of the planet. The fact that trees have this ability suggests that they have the power to change the composition of the atmosphere around us.

Answer:
enzymes change the base sequence of the primary transcript and therefore the protein for which it codes.
Explanation:
RNA editing refers to the post-transcriptional mechanisms by which nucleotide modifications are introduced into an RNA chain. The RNA editing processes exclude modifications produced during RNA splicing and polyadenylation. For example, deamination is an RNA editing mechanism by which an amine group from cytidine is removed by specific cytidine deaminase enzymes, thereby resulting in uridine (C to U).

What describes natural rights?
Natural rights are those that are independent of the laws or customs of any particular culture or government, and so are universal, fundamental and inalienable
These rights were bestowed by God and cannot ever be taken away or even ceded. These fundamental natural rights are "life, liberty, and property,"
Human laws cannot nullify them, but an individual can lose the ability to enjoy them by acting in a certain way, like by wrongfully abusing the rights of others.
Natural rights are not generally embraced, in part because of their apparent incoherence and religious connotations.
Some philosophers contend that only legal rights exist and that there are no natural rights; for example, Jeremy Bentham referred to natural rights as "simple nonsense."

The cell cycle is an organized series of processes that take place in a cell before cell division.
What is Cell cycle?The cell cycle is a four-stage procedure in which the cell enlarges (gap 1, or G1), copies its DNA (synthesis, or S), gets ready to divide (gap 2, or G2), and splits (gap 4, or S).
Interphase, which accounts for the time between cell divisions, is made up of the stages G1, S, and G2. A cell "decides" whether to enter the cell cycle and divide based on the stimulatory and inhibitory signals it receives.
Growth factors, growth factor receptors, signal transducers, and nuclear regulatory proteins are the four groups that can be used to categorize the proteins that are involved in promoting cell division.

What assumption do we make about an isolated bacterial colony that formed on an agar plate?
When an isolated bacterial colony is discovered on an agar plate, there are a few assumptions that are typically made.
Firstly, it is assumed that the bacteria are a single species, which means that all of the bacteria in the colony are genetically related. This allows scientists to identify the bacteria by its unique characteristics, such as its color and size. Secondly, it is assumed that the bacteria are capable of reproducing, since it is only possible for the colony to form if the bacteria are able to divide and multiply. Lastly, it is assumed that the bacteria are not contaminated with any other microorganisms, since the bacteria need to be isolated in order to form a colony.
These assumptions allow scientists to accurately identify the bacteria and gain a better understanding of its characteristics. This knowledge can then be used to further research and study the bacteria, as well as develop treatments or vaccines if necessary. Therefore, these assumptions are essential in understanding the biology of the bacteria and its potential implications on human health.

D

patterns of reversed and normal magnetic polarity.
Answer:
Oceanic crusts on both sides of the ridge shows matching patterns of reversed and normal magnetic polarity.
Explanation:
Mid-Atlantic Ridge is a collection of mountains that settle at the bottom of the ocean. These mountains are the result of the movement of the plates. The breakdown of these mountains was very important to give truth to the theory that defended the existence of the expansion of the ocean floor and continental drift. That's because by looking at the mid-Atlantic Ridge, scientists were able to see that the oceanic crusts on both sides of the mid-Atlantic Ridge had patterns corresponding to normal and reverse magnetic polarity. This was the basis for perceiving the movement of the ocean's bottom in random directions.
