Answer:
Because salt is an agent that attracts and draws out water, the surrounding salt water draws water from inside the fish so they must constantly drink water to replace the lost water in their system. The process of water being drawn out of the body by the surrounding water of higher salt levels is known as osmosis.

Answer:
Honestly it is hard to find breeders of that type because u said yourself
Explanation:
that they are rare ans i would say more delicate thats why people don't really breed them because of the breeder effort to make them perfect for the buyer. i honestly don't know where to find them but u could try places like el monte and areas or cities like that

1. In a soil ecosystem, matter _________________ and energy ___________________.
Answer:
Recycled, not recycled
Explanation:
In a soil ecosystem, matter is recycled and energy isn't recycled.
Matter is recycled through biogeochemical cycles. Matter has to be recycled because it can neither be created, nor destroyed, and as such, recycling is the only option left.
Energy isn't recycled because most of the energy gotten is used by organisms, as gotten from the plants already, and thus, when it gets to the food chain there isn't much left to be recycled.

Do cancer cells block nerve connections?
Answer:
Yes
Explanation:
Many different cancers can metastasize to the nervous system, but breast, lung, and skin cancers are the most common to do so.
Answer: Both interventions prompted cancer cells to recruit and nourish nearby blood vessels that, in turn, fueled their growth. Blocking the receptors prevented this growth. That study and others showed cancer cells were alert to signals from the nervous system.

Explain how Karen’s science project demonstrates capillary action in the following scenario.
For her science project, Karen brought two clear glasses of water. She put a large, clear straw in one glass. Karen tried to suck up the water in the glass without the straw by hovering over the water and creating suction with her lips, but she did not touch her lips to the water. The water did not suction into her mouth. In the other glass, Karen sucked through the straw, and her audience could see the water was transported from the glass to her lips.
Answer:
Capillary action explained in the following scenario above, because if you picture the roots as the cup, the water as the water, the straw as the channels, and Karen as the plant. As Karen sucked through the straw, it was as the plant was sucking up the water through the channel from the roots. The water transported from the glass to her lips it was an example of the roots holding the water and transporting it to the plants by the channel.

Which of the following statements best describes the role of adenylyl cyclase in
the epinephrine signaling pathway?
A.It converts a polymer to its monomer subunits.
B.It moves substances across the plasma membrane.
ect!
C.It accelerates the production of a second messenger.
D.It transfers phosphate groups from to protein substrates.
Answer:
C.It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP), a second messenger that activates the protein kinase A (PK-A) protein by dissociation of its regulatory subunit from the catalytic subunit. The first step of the epinephrine signaling pathway consists of the hormone binding to the epinephrine receptor localized on the cell surface. This binding activates a G protein inside the cell, which in turn activates the adenylyl cyclase enzyme. Subsequently, adenylyl cyclase converts ATP molecules into cAMP molecules. Since cAMP transports the message of the epinephrine hormone within the cell this molecule (cAMP) is considered to be a second messenger. Finally, cAMP activates the PK-A enzyme which phosphorylates different proteins and thus triggers different biological processes.
Which of the following pituitary hormones controls the production and releases of glucocorticoids from the adrenal cortex

Which two layers are part of the thermosphere?
exosphere and ionosphere
ionosphere and mesosphere
mesosphere and stratosphere
stratosphere and troposphere
Answer:
The exosphere and the ionosphere
According to the research, exosphere and ionosphere are two layers that are part of the thermosphere.
What is the thermosphere?It is one of the layers that make up the Earth's atmosphere characterized by X-rays, gamma and ultraviolet rays that cause sodium molecules and atoms to ionize, increasing the temperature.
Due to this peculiarity, the thermosphere includes the ionosphere, where ionization processes take place and the exosphere is the layer with the lowest density.
Therefore, we can conclude that according to the research, exosphere and ionosphere are two layers that are part of the thermosphere.

3. Three redwood trees are kept at different humidity levels inside a greenhouse for 12 weeks.
One tree is left outside in normal conditions. The heights of the trees are measured once a
week.
IV humidity levels
DV height
CG tree left outside
Answer:
This question is asking to identify the following:
Independent variable: Different humidity levels
Dependent variable: Height of the plant
Control group: Tree left outside in normal conditions
Controlled variable: same time of measurements (once in a week), same types of trees
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, three redwood trees are kept at different humidity levels. Hence, the independent variable is the DIFFERENT HUMIDITY LEVELS the redwood trees were kept at.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this case, the HEIGHTS of the trees measured is the dependent variable.
Controlled variable or constants are those variables that must be kept unchanged throughout the experiment for all groups. In this experiment, the constants are: same time of measurements (once in a week), same types of trees (redwood).
Control group is the the group in an experiment that does not receive experimental treatment. In this case, the group that does not receive treatment/control group is: Tree left outside in normal conditions.

Jake broke his fibula and had to wear a cast for six weeks. The muscles attaching to this bone atrophied (shrank) during this time. What muscle function would Jake be unable to perform well as a result?
Answer:
Explanation:
One of the functions of the muscle is the storage of amino acids which can be used for energy production when demands are high or for protein synthesis. But during muscle atrophy, this function becomes reduced which could lead to the particularly muscle been unable to stretch or contract due to weakness, it could also lead to the imbalance between protein synthesis and degradation.
Species in which dark brown fur (D) is dominant relative to light brown fur (d). Using the Punnett square below, predict the frequencies of the genotypes and phenotypes of the offspring from dark brown parents two who are heterozygous (Dd genotypes).
Answer:
Genotype frequencies25% DD
50% Dd
25% dd
or
1 DD: 2 Dd: 1 dd
Phenotype frequencies75% Dark brown, 25% light brown
or 3 dark brown: 1 light brown
Explanation:
Two heterozygous parents have the genotypes Dd. Therefore, the cross is Dd x Dd.
D d
D DD Dd
d Dd dd
25% (1:4) of the organisms have the genotype DD, and therefore the phenotype is dark brown, since it has two copies of the dark brown fur allele (DD)
50% (1:2) of the organisms have the genotype Dd, and therefore, the phenotype is dark brown since dark brown fur (D) is dominant to light brown fur (d).
25% (1:4) of the organisms have the genotype dd, and therefore the phenotype is light brown, since it has two copies of the light brown fur allele (DD)

What do you mean by amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.
Moreover, amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Therefore, these 12 amino acids are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine and arginine.

How can the expression of a single gene be quickly, efficiently, and specifically shut down at the transcriptional, posttranscriptional, and posttranslational stages through coordinated expression of a transcriptional repressor, an miRNA, and a ubiquitin ligase?
Answer:
Ubiquitin ligase is a protein enzyme recruits Ubiquitin-conjugating enzyme that come with the ubiquitin and catalyzes the transfer of ubiquitin to the protein substrate of interest and destructed by the proteosome.
miRNA are small RNA molecules with no coding behavior that binds with the mRNA with the help of base pairing of complementary codes. It helps in mRNA degradation and cutting of poly-A tail of mRNA type of gene expressing.
A gene-specific transcriptional repressor helps in preventing the transcription process of the mRNA by inhibiting the binding of the RNA polymerase to the promoter.
