Answer - True

Reasoning - The reason is without predation the animals will die since if they won't hunt they won't eat and die. Yes it's important to because it helps maintain the ecosystem. For example a Tiger is on top of the food chain so it's to gotta hunt. Just like down those line of chains.

In an electrochemical cell, q = 0.0010 and k = 0.10. what can you conclude about ecell and e∘cell? in an electrochemical cell, =

Iteru [2.4K]

If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive

Fill in the blank Competition drives natural selection as individual members of a species compete with each other for limited na

maks197457 [2]

Answer:

1. Intraspecific

2. speciation

3. fossil record

4. The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

5. A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

6. A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

7. Fossils provide a great many intermediaries that connect past species with their living descendants.

8. Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.

Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds

bazaltina [42]

Answer:

(a) Gg × Gg; (b) genotypic = 1:2:1, phenotypic = 3:1

Explanation:

a) A cross between two gray seeded plants produces progeny with gray and white seeds in 3:1 ratio (302:98=3:1). This means that the parent plants are heterozygous and each has at least one recessive allele. If the allele "G" is responsible for gray seed and the allele "g" imparts white color to the seeds, the genotype of the heterozygous parents would be "Gg".

b) A cross between two heterozygous gray seeded parents would produce progeny in following ratio:

Genotype ratio= 1 GG: 2 Gg: 1 gg

Phenotype ratio= 3 Gray: 1 white

What are two functions of cell surface markers?

svetlana [45]

There are 2 functions for cell surface markers. The first is to recognize the outside cell. The second is to allow the cell to bind to substances outside the cell. Cell surface markers are proteins expressed on the surface of cells that often conveniently serve as markers of specific cell types. There are different types of cell surface markers. These markers are vital for the human body to function. These markers also vitally affect the functions of other biological systems of other organisms and creatures such as animals.
