Which of the following describe density-dependent factors? They act to regulate population growth. They can affect birth rates o

r death rates. One example would be intraspecific competition for resources. They are especially important in K-selected populations. They do not involve biological interactions. They can affect growth rates but not population size.

Answer:

Correct options are

a) They act to regulate population growth.

b) They can affect birth rates or death rates

c) One example would be intraspecific competition for resources.

Explanation:

Population growth rates can be regulated by the density of a population and hence population regulation is a density-dependent process.  Density-dependent factors include disease, competition, and predation.  

The higher the population density, the higher is the mortality rate.  

Some of the biotic density dependent factors are  

a) intra- and interspecific competition

b) reducing population’s rate of growth

c) Individual’s reproductive rate

Hence, the correct options are

So the correct options are

a) They act to regulate population growth.

b) They can affect birth rates or death rates

c) One example would be intraspecific competition for resources.

What statement most directly demonstrates a way that the geosphere is involved in the nitrogen cycle
Ulleksa [173]

B. bacteria that convert ammonia into nitrites and nitrates are found in the soil  

This statement best demonstrates a way that the geo-sphere is involved in the nitrogen cycle.

A nitrogen cycle is defined as the movement of nitrogen between the atmosphere, biosphere, and geo-sphere in different forms. Ammonia is converted to nitrates by nitrifying bacteria in the soil. Then the plants absorb these nitrates from the soil and use these to build up proteins.

What is synthesized from the DNA template? This is used to assemble ______ into ______.
Vladimir79 [104]
Answer:
            The right option for blanks is mRNA, amino acids and polypeptide chain (protein).

Reason:
             During protein synthesis first of all mRNA formation occurs from DNA template. Then mRNA come out from nucleus into cytoplasm and bind with ribosome, where tRNA come and binds to mRNA codon with the help of anticodons. and add amino acids. In this way a chain of polypeptide is formed.
