Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.

When comparing 2 populations of animals, which statement most likely indicates that
they are the same species?
Answer:
they are able to produce fertile offspring
Explanation:
A species is a group of organisms that are able to produce fertile offspring. This criterion is the basis of the biological concept of species proposed by Mayr in 1970, who defined a species as a group of genetically similar interfertile populations which are reproductively isolated from other groups. In consequence, only those populations whose individuals can interbreed (mate) with one another to produce viable and fertile offspring must be considered to be part of the same species.

A skunk living in the northern part of the United States is exposed to extreme cold and food shortages during the long winter months.
Based on the climate, what do you predict the skunk's innate response to these environmental factors will be?
A: Increase cellular respiration and ATP production
B:Estivate with a period of dormancy until the warmer weather arrives
C:Migrate to regions of warmer weather
D:Slow down its metabolic rate and lower its body temperature
Answer: cccccccc
Explanation:
Answer:
I think the answer should be B, because skunk doesn't migrate or hibernate, and A doesn't make sense because when animal facing temperature drop and food shortage they do not speed up metabolic process, instead they will slowdown the metabolic process and save as much energy as possible.

Can someone help me with the order of the carbon cycle ?
Answer:
First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Which of the following is not a characteristic of enzymes?
Each is used to break down substances.
Each has a specific substrate.
Each has an optimal temperature and pH.
O
Each has an active site.
Answer:
Each is used to break down substances.
Explanation:
Enzymes merely speed up a chemical reaction, not necessarily break down substances.
Each enzyme is used to break down substances is not a characteristic of enzymes. The correct option is A.
Thus, enzymes aren't just utilized to degrade things. Enzymes perform additional crucial tasks in addition to being essential for the breakdown (catabolism) of substances. In living things, enzymes operate as biological catalysts to quicken chemical processes.
Enzymes achieve this by reducing the activation energy needed for a reaction to happen and thereby speeding up the reaction rate. While some enzymes are engaged in the breakdown of chemicals, others are involved in the synthesis or modification of other molecules (anabolism).
Thus, the ideal selection is option A.

6. Compare the DNA of an offspring to the DNA of its parents.
Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).
The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.
How does the DNA of parents compare to that of offspring?In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.
During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.
Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

What is the life cycle of the sun? What are the phases of its life? Birth What is it now? ________________ What will it become? ______________ What will it be called as it dies out? _______________
Answer:
Main sequence, red giant, white dwarf.
Explanation:
The life cycle of the sun is called as solar cycle and is the phase of solar development. There are about seven-stage in its life cycle. Starting with the birth of the sun that is found in the solar nebula theory took place about 4.56 billion years. The sun starts to enter the T Tauri stage, followed by the main sequence stage where the sun is currently in. After this stage that is when the sun runs out of hydrogen from its core. It will produce violent helium flashes and will shrink its size. When this happens it will reach the tip of the red giant stage. Later on, the naked core will form into a white dwarf.explain how mutation evolution might
occur in a population
Answer:
mutations create a new particular gene, a new allele. If that allele is passed down to the next offspring and the next, the mutation would be carried throughout the population. Some of the species in the population might not show any symptoms of a mutation or not feel the effects of it, but pass it down. If the mutation is neutral (causing no harm or no good), it may be passed down. If the mutation is beneficial to the species, and helps them survive, it may be passed down more. If the mutation is harmful, the mutation may eventually stop being passed down, and start to only appear if something happens genetically (mutation still may happen, but not because of passing down from parent to offspring).

Answer:
The correct answer is - Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins, vena cavae
Explanation:
Throughout the vascular system or cardiovascular system, the drop of deoxygenated blood moves through right atrium and right ventricle to the lungs within the pulmonary arteries. Then the oxygenated blood transfers via pulmonary veins t the left atrium of the heart that pumps the oxygenated to the rest of the body by the left ventricle through the aorta.
Arteries help in the flow of the systemic circulation then blood moves from arterioles to capillaries. The deoxygenated blood is returned through the veins to the heart that come to the superior and inferior vena cava and back to right atrium and cirlculation repeat again.
