Answer:
The correct answer is - e. many different molecules form a signaling cascade.
Explanation:
Signal transduction is the number of events that take place inside the body of a human from the external atmosphere to transmitting a chemical or physical signal through a number of molecular events of signaling cascade.
The transmission of the particular chemical or physical signal is caused a sequence of phosphorylation events inside the cell it involves specific protein receptors and different types of molecules.

a)decrease in ozone levels
b)burning of fossil fuels
c)changes in the atmosphere
d)changes in the climate
Answer:
b burning of fossil fuels
Explanation:
Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
O True
O False
Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
Some of the principal human activities responsible for biodiversity loss are
the uncontrolled use of unrenewable resources, overexploitation of renewable resources; land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures; the unplanned advance of cities, and opening of new roads to connect those cities.All of them involving
deforestation and fragmentation of natural landscapes; water, air, and soil pollution, species loss, and reduction of biodiversity.With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
The respect for nature, People´s education at different levels to care and protect wildlife, Interest in keeping ancestral knowledge, Planning and previous environmental impact studies, Policies to control human activities, Caring involved government.If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.

What might happen to the salinity of the ocean if animals were no longer living in it?
The salinity of the ocean and oceanic animals are not related. Living organisms are not the cause of the salt in the ocean, so if they no longer lived there would be no change.

Which of these is a difference between DNA and RNA?
DNA is found in the nucleus; RNA is never found in the nucleus.
DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What happens if the mass of the elements is greater compared to smaller ?
Hello. More information is needed to answer your question accurately. However, I will try to help you in the best possible way
If you are referring to what happens if the mass of an atom is greater compared to an atomic number, we can say that there is nothing too much, since it is normal for the atoms to have a mass slightly greater than the atomic number. The mass of an atom can never be less than the number of protons added to the number of neutrons. An atom with greater mass has a greater number of electrons and neutrons in relation to an atom of less mass and it is likely that the atom of less mass will donate or share electron with the atom of greater mass so that both reach the electric balance.

What is the biological impact of minimum catch sizes on a population of fish? a. The population comes to be dominated by smaller, slower-growing individuals. b. Older, less productive adults are removed, improving the population’s health. c. It applies a selective pressure for larger, faster growing fish. d. The fish in the population produce more and healthier eggs to compensate.
Answer: The population comes to be dominated by smaller, slower-growing individuals
Explanation:
The minimum catch size simply refers to the shortest allowed length that is required for a caught fish. It should be noted that the minimum catch ensures sustainability with regards to the use of fish stocks and also helps in the promotion of the recovery of some fish.
Lastly, a biological impact of minimum catch sizes on a population of fish is that population comes to be dominated by smaller, slower-growing individuals.
Answer:
Explanation:
The answer is A.) The population comes to be dominated by smaller, slower-growing individuals.

The moray eel and grouper fish hunt together. When both hunt together, prey barely stands a chance: hide in the reef, the eel eats you; dash for open water, the grouper grabs you. Which symbiotic relationship is described above?
A. Coevolution
b. Mutualism
c. Parasitism
d. Commensalism
Answer:
We can immediately cross-out C
We can also cross-out A.
Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
I would say D: Commensalism. Both fish can survive without each other.
