Evaporation. Transpiration and photosynthesis deal with plants, living things. Sweating with humans, living things. Evaporation does not, therefore leaving it the only option left.

Answer:

The nonliving processes such as evaporation, precipitation, etc., water returns back into the atmosphere.

Explanation:

Water moves through the help of living organisms in an ecosystem.

Although, the non-livings processes are also the main partners of this process.

Plants absorbs water through their root system and loss by transpiration.

Water also moves through the living organisms in an ecosystem.

Other nonliving processes such as evaporation, precipitation, water returns back into the atmosphere.

A scientist investigated DNA replication in two groups of cells, labeled A and B. She injected radioactively labeled nucleotides

hichkok12 [17]

Answer:

A is a eukaryotic cell while B is a prokaryotic cell

Explanation:

The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.

In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.

Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.

Although selection operates against deleterious alleles in populations, they are rarely lost from these populations. For example

KonstantinChe [14]

Answer:

Deleterious alleles appear sporadically in a population

Explanation:

A population with a deleterious allele will have no or few individuals that have the ability to pass along these traits. These alleles appear less in a population because of selective pressure but they are not always absent. The alleles appear less often but are are not always passed on and the others that are genetically fit are able to pass along their genes. The reason the population equilibrium is not zero is because these alleles do appear but they are not necessarily passed along. These individuals may not be able to reproduce or reach the age of reproduction.

Deleterious alleles appear more often, making individuals less fit genetically, i.e. they pass fewer copies of their genes to future generations. Put another way, natural selection purges the deleterious alleles.

Many traits (phenotypes), like eye color, are controlled by multiple genes. If eye color were controlled by the number of genes

mel-nik [20]

Answer:

Explanation:

If there are 5 genes, let us assume that they are in the alternative forms with 2 possible gets for each five... So we have

2 possible gametes for each five = 2 to the power of 5 = 32 gametes

Then genotypes = 3 to the power of 5 = 243

The same also for 10 genes

2 possible gametes for each 10 = 2 to the power of 10 = 1024 gametes

Then genotypes = 3 to the power of 10 = 59,049

The same also for 20 genes

2 possible gametes for each 20 = 2 to the power of 20= 1,048,576

Them genotypes = 3 to the power of 20 = 3,486,784,401
