A transcriptional repressor that controls the transcription of gene A is not normally active unless bound by an effector molecul

e X. In a certain cell, the domain of the repressor that binds to the silencer of gene A is mutated so that the repressor-X complex can no longer bind to its recognition site. With all other factors being the same, what effect do you predict on the transcription of gene A if X is increased in the cell and the cell is already expressing gene A

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.

Answer:

Abiotic factors, such as temperature, water, sunlight amounts, and regional terrain, directly effect biotic factors. Biotic factors are the living components of an ecosystem which include primary producers, consumers, and dexomposers.

Abiotic factors can effect organisms in many ways. Hey can effect primary producers negatively if there is too little sun, water, or nutrients in the soil. However, if there is too much of any one of these, they can still be negatively effected. With primary producers, it’s all about balance.

while consumers do not directly require the above conditions, they do rely on the plants and animals that feed on said plants to survive. If the plants do not have correct nutrients, they will not either. As far as terrain goes, they adapt to better cope with the environment. If they live in an aquatic enviromment for example, they acquire ways to more efficiently move through the water to look for food.

Decomposers rely on the remains of dead plants and animals in order to survive. They feed off of dead matter and the waste gets deposited into the soil. This in turn helps to give the soil its nutrients, and so the cycle continues.

Everything in nature is reliant on each other. This delicate balancing act is both beautiful and so very fragile. If one organism is removed, the entire ecosystem could suffer. This is why it is so critical to protect the environment we share with every other living creature on this earth.

American vultures used to be classified in the same family as African vultures. Which discovery caused scientists to reclassify
Mashutka [201]

Answer:

DNA evidence revealed the American vultures share more recent ancestor with the Storks

Explanation:

The hooded vultures that is mostly found in the African continent have a close resemblance with the American vultures and were traditionally classified to belong to the Falcon family.

However, it was observed that the American vultures shared a similar behavior with Stork which is not common to the vulture found in Africa, including the hooded vulture. The Stork and the American vulture exhibit the behavior of urinating on their legs when being overheated. When the urine gets evaporated, it helps them to cool their body temperature.

This shared behavior between the storks and the American vultures led scientists into using molecular analysis in analyzing the DNA of the hooded vultures found in Africa, the American vultures, and the stork.

Evidence from the DNA analysis later revealed that the American vultures and the storks share a more common DNA sequences than African vultures and American vultures do.

62 Which law of motion accounts for the following statement? "When a marble
svp [43]

Answer:

the answer is Newton's third and Second law

Explanation:

Newton's second law tells us that the force that is generated on a body is proportional to the acceleration it acquires.

F= M*A

at lower mass greater acceleration

Newton's third law explains that for each force that acts on a body, it performs a force of equal intensity and direction but in the opposite direction to the body than gender.

I hope it's help you
