Explanation:
If the evaporation rate is higher than the precipitation rate, what will happen to a lake?
Answer:
it will eventually dry out
Answer:
It will eventually evaporate.
Explanation:
if you have more water evaporating (turning into clouds) than precipitating (raining) than eventually the whole lake will be evaporated. Because there will be no more water to evaporate if the rate stays the same.
What human activity has been important in the Cross Timbers and prairies for many years?
Because the human embryo is able to split during early cleavage or blastocyst formation to produce two viable progeny, it is said to exhibit _______ development.
Answer:
This question lacks options, options are:
a) indirect
b) mosaic
c) determinative
d) regulative
e) direct.
The correct answer is d.
Explanation:
The egg (ovum) like the embryo during the first embryonic divisions, do not possess any sign of polarity. This development mechanism can be called regulative development(in contrast to the mosaic model) since the fate of the cells that originate is not fixed and can be modified during development. In regulative embryos, part of the embryo can be removed and the remaining cells can compensate for the loss and give a complete individual as the final product.The strongest evidence that continues to support this regulatory model is based on the plasticity or potential that mammalian cells possess before implantation. It is known that the blastomeres produced by the first divisions can be replaced with each other or even can be eliminated without apparently altering the embryonic development and therefore they are equivalent (without polarity).
Researchers have found a general relationship between testicular cancer and exercise.Increased exercise is associated with a decrease in incidence of testicular cancer.However,a positive relationship (increased incidence of testicular cancer)was found between testicular cancer and riding bikes or horses.Several factors might be hypothesized to bring about this result.Which of these hypotheses is properly related to a prediction that arises from it?
A) Hypothesis: Riding bikes or horses causes trauma to the testes.Prediction: Bike or horse riding will cause testes to shrink.
B) Hypothesis: The seat on bikes and the saddle on horses are made of material containing chemicals that damage testicular cells.Prediction: Chemicals found in bike seats or horse saddles damage testicular cells.
C) Hypothesis: Riding bikes or horses increases scrotal temperature,which damages testicular cells.Prediction: Bike riders are more likely to wear briefs than boxers as their underwear of choice.
D) Hypothesis: Mutations that lead to testicular cancer make men more likely to ride bikes or horses.Prediction: Men who ride bikes or horses have a higher rate of mutations than nonriders.

What does gene expression control?
a. the proteins that are made by the cell
b. the rate at which DNA replication occurs
c. the duration between cell cycles
d. the division of the cell nucleus
Answer:
a
Explanation:
Control of gene expression ,
1)Transcriptional control : controls when and how often the gene is being transcribed.
2)Post-transcriptional control :
- RNA process control determines how often RNA is been processed.
- RNA transport and location control : selection of mRNA to be transported to
cytosol.
- mRNA degeneration control ; selection of which mRNA is getting destabilized.
3)Translational control ; section of which mRNA is being translated.
4) Protein activity control / post-translational control ; regulation of proteins by activation , deactivation, degeneration, compartmentalization and modification of protein.
Gene expression control the proteins that are made by the cell. So, the correct option is A.
What is Gene expression?Gene expression is the procedure through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
A finely controlled process called gene expression enables a cell to react to its changing surroundings. It serves as both a headphone jack that raises or lowers the level of proteins produced as well as an on/off switch to regulate when proteins are created. Transcription and translation are the two essential processes that go into the creation of a protein. Gene expression control the proteins that are made by the cell.
Therefore, the correct option is A.

Does stomach lining, liver, skin repair itself the fastest
The stomach lining is able to heal itself the fastest, followed by the skin, and then the liver.
What do you mean by the stomach lining?
The stomach lining is the innermost layer of the stomach, made up of cells that produce digestive enzymes and secretions that help break down food. This layer also helps protect the stomach from the acidic environment within the stomach.
The stomach lining is able to heal itself quickly because it contains specialized cells that can quickly make new tissue to replace damaged cells. The skin is also able to heal quickly because it is made up of many layers of cells that can quickly reproduce to form new skin. The liver is able to regenerate itself, but it takes longer than the stomach lining or skin because the liver is made up of fewer cells and the process of regeneration is more complex.

What are the hereditary diseases?
Sickle cell anemia, cystic fibrosis, and hemophilia are some of the hereditary diseases that occur because of changes in the genetic make of an organism.
Hereditary diseases usually referred to as inherited diseases or genetic disorders, are a group of genetic diseases that are brought on by changes in a person's genetic makeup (DNA). These changes are caused by mutation. This occurs when the normal bases in the DNA is replaced with the faulty base or mismatched base.
Then, these illnesses are passed down from one generation to the next, or in other words, they are inherited from one set of parents to another. For example, sickle cell anemia, cystic fibrosis, and hemophilia are some examples of hereditary diseases.
Because sickle hemoglobin requires two copies of the gene to be present, sickle cell anemia is referred to as a recessive condition. They must get one from each parent, which code for abnormal hemoglobin.

what are in the synaptic knobs that then travel across the synaptic cleft to initiate a response in the next cell
Neurotransmitter molecules penetrate the synaptic cleft and attach to receptor proteins on postsynaptic cells.
Synapses can be thought of as converting an electrical signal (the action potential) into a chemical signal in the form of neurotransmitter release, and then switching the signal back into an electrical form when the transmitter binds to the postsynaptic receptor.
These stimulate the production of "neurotransmitters," which pass the impulse across the "synapse to the next neuron." After a nerve impulse releases "neurotransmitters," these "chemical messengers" travel over the tiny "synaptic gap" and are taken up by specialized receptors on the surface of the next cell.

The non-poisonous ____ butterfly gains protection by looking like the bad-tasting ____ butterfly, which is a protective device known as ____.
The non-poisonous viceroy butterfly gains protection by looking like the bad tasting monarch butterfly, which is a protective device known as Mimicry.
Mimicry is a biological phenomenon that occurs by superficial resemblance of two or more organisms that are not closely related taxonomically. The resemblance gives an advantage such as protection from predation upon one or both organisms by which the organism deceive the animate agents of natural selection.The predator interacts with the similar organisms and gets deceived by their similarity.
The discovery of Mimicry in butterflies was in the mid 19th century by Victorian naturalist H.W.Bates. Mimicry in butterflies are of two types- Batesian mimicry and Mullerian mimicry.
The Batesian mimicry is when a non-poisonous animal mimics the pattern or coloration of a poisonous or unpalatable animal without actually producing any toxins themselves.
The Mullerian mimicry is when two poisonous or unpalatable animals have the same coloration and patterns.

Explain how the result show that both light and chlorophyll must be present for photosynthesis.
Chlorophyll absorbs energy from blue and red light waves during photosynthesis while reflecting green light waves, giving the appearance of a green plant.
Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue. Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Despite the fact that there are numerous steps involved in photosynthesis, there are primarily two stages: light-dependent reactions and light-independent reactions. The light-dependent reaction, as its name implies, occurs inside the thylakoid membrane and necessitates a constant supply of sunshine. The light waves' energy is captured by the chlorophyll and transformed into chemical energy in the form of the molecules ATP and NADPH.
The Calvin Cycle's light-independent stage, which takes place in the stroma, or region between the chloroplast and thylakoid membranes, does not require light, hence the name light-independent reaction. In this phase, carbon dioxide is converted into carbohydrates like glucose using energy from the ATP and NADPH molecules. However, not all types of photosynthesis are made equal. C3 photosynthesis and C4 photosynthesis are two of the various forms of photosynthesis. The majority of plants engage in C3 photosynthesis. It entails the Calvin Cycle producing 3-phosphoglyceric acid, a three-carbon molecule that later transforms into glucose.
