in cells regulation allows rapid response to changes in the environment; in cells, gene regulation is critical for maintaining homeostasis.
Given what we know about biological mechanisms, we can confirm that both of these statements are in fact true in regards to regulation and gene expression.
Homeostasis is the body's ability to maintain constant a series of processes and values that we need in order to survive. To do this, regulation in cells is essential. Regulation allows us to respond rapidly to changes in the environment by regulating the processes which control the homeostasis for that environmental change.
Gene regulation or expression is another way in which the body maintains homeostasis. For example, in the presence of too much substrate, the gene encoding a specific enzyme might activate, causing the creation of the enzyme and getting substrate levels back to normal.
Inversely, if the body detects that substrate levels may be too low, the expression of any gene that may consume that substrate can be silenced, therefore maintaining a balanced level.

B. a likelihood based on the chance that a particular event will or will not occur during an experiment
C. a testable explanation or answer to a scientific question based on prior knowledge or research
D. a statement of fact that is accepted as true because it has always been observed to be true through observations and experimentation
Answer:
I know I am too late to help you, but I couldn't find an answer when looking for this question. I got it right and it is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation.
Explanation:
Evolution by way of natural selection is most likely an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation. The correct option is A.
What is natural selection?Natural selection is the process through which organisms that are more adapted to their environment tend to survive and reproduce more than those that are not. Tree frogs, for example, are occasionally eaten by snakes and birds.
Evolution is a process in which living things or other evolve or change over time. Natural selection is also a reason for evolution, which takes a large amount of time.
Therefore, the correct option is A. an explanation of phenomena that can be accepted as true because it is supported by repeated observations and experimentation

which process is typical of cancer?
-Replacement Of Damaged Lungs
-DNA Replication
-Cellular Death
-Uncontrolled Cell Division
Answer:
Uncontrolled cell division
(and I think that HIV/AIDS Does the opposite; slows cell division)
Answer:
uncontrolled cell division
Explanation:
Cancer cells are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy. Over time, these cells become increasingly resistant to the controls that maintain normal tissue — and as a result, they divide more rapidly than their progenitors and become less dependent on signals from other cells. Cancer cells even evade programmed cell death, despite the fact that their multiple abnormalities would normally make them prime targets for apoptosis. In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body.

Predict how many different mRNA sequences could code for the following amino acid sequence plus a stop codon: Met-Trp-Cys-(Stop).
Answer: 6
Explanation:
This is because the Met and Trp are coded by one codon, Cys is coded by two different codons, and Stop is encoded by three different codons. Therefor, 2x3=6.

Think about the importance of energy. Without a source of energy organisms cannot respond, build, reproduce, or carry out most of the functions of living things. From where does our energy come? Explain how Photosynthesis and Cellular Respiration are important in your everyday life. Be Scientific! 5-6 sentences!
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathway through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.
What is energy?Energy is the ability to do work. All living organisms require energy to do work. Energy is transformed to chemical energy in plant cells through a process called photosynthesis.
Plants utilise the chemical energy stored during photosynthesis in their cellular respiration for essential life functions. Energy is changed during both photosynthesis and cellular respiration.
The light-dependent and light-independent processes of photosynthesis are also important for plant management.
Therefore, Photosynthesis is a very important process in plants. It helps in the formation of glucose in plants. Cellular respiration takes place in human beings.

Answer: One of the bonds was sold at face value while another was sold below face value.
Explanation: I took the quick check
A bond was sold at its face value, while another was sold for less.
What is the investment?An investment is a purchase undertaken with the hope of earning money or increasing capital. Appreciation is the term for an asset's value rising over time. When someone invests in a product, they do not aim to use it for immediate consumption but rather as a means of generating money in the future.
An investment always entails the use of some resource today, such as time, money, effort, or an item, with the hope of receiving a return that is higher than the initial investment. An investor might, for instance, purchase a financial asset right away in anticipation that it would generate income over the road or be able to be sold for a profit at a higher price.
Therefore, A bond was sold at its face value, while another was sold for less.

the major way that meiosis ii differs from mitosis is that
Meiosis and mitosis are forms of cell divisions that occurs in cells in eukaryotes. This forms of division enables growth and development.
The major way meiosis ii differ from mitosis is that in meiosis II, the daughter cells formed are haploid cells.
Mitosis is also termed as an equational division meaning that the end result yields the same number as the beginning, there is no reduction and resulting cells are still diploid.
In meiosis, there is the reduction in half first in meiosis I then the homologous chromosomes separates at the centromeres in meiosis II resulting in haploid cells.

Which of the following is a binocular cue for depth perception?.
A binocular cue used to assess depth between two nearby objects is called retinal disparity.
What is the binocular cue for depth perception?The pictures that both eyes focus on to create stereopsis, or the feeling of depth, is known as binocular depth cues. Using binoculars, one may see the world in three dimensions.
Binocular depth signals can be classified as either retinal disparity or convergence. Convergence centers on a single object while using both eyes.
A binocular cue used to assess depth between two nearby objects is called retinal disparity. It accomplishes this by contrasting the various pictures from the two retinas. Because the distance between each eye is typically around two and a half inches, each eye sees different pictures.
Therefore, the retinal disparity is a binocular cue for depth perception.

Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.
Removal of invasive species and growing more vegetation can restore the stability and biodiversity of ecosystem.
These two solutions restores the stability and biodiversity of the selected ecosystem because invasive species can capture more resources as compared to local species which leads to the extinction of local species.
While on the other hand, growing more vegetation provides more food to the organisms which ultimately increases the biodiversity of the ecosystem so we can conclude that removal of invasive species and growing more vegetation are the solutions to bring ecosystem in a stable condition.
