Answer:

b. the new species must be unable to breed with the original species.

Explanation:

By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.

These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:

  1. Habitat isolation: Two species occupy entirely different and distant habitats.
  2. Temporal isolation: Two species  procreate at different times of the year.
  3. Behavioral isolation: Two species exhibit different mating behaviors.
  4. Gametic isolation: The gametes of the two species cannot fertilize.
  5. Mechanical isolation

Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.

Choose all of the ways that cellular respiration is different from photosynthesis. Select the 4 correct answers. *
shepuryov [24]

Answer:

It uses glucose as a reactant.

It uses oxygen as a reactant.

It makes ATP.

It happens in the mitochondria.

Explanation:

It occurs in cells.  - this is false. Both cellular respiration and photosynthesis occur in cells.

It uses glucose as a reactant.  - this is true. Cellular respiration uses glucose as a reactant, it is broken down to release energy. Photosynthesis produces glucose.

It uses oxygen as a reactant.  - this is true. Cellular respiration uses oxygen as a reactant. In contrast, photosynthesis releases oxygen as a byproduct

It makes ATP. - this is true. Cellular respiration makes ATP. Photosynthesis uses energy to produce the sugar which is used in cellular respiration to synthesise ATP.

It happens in the chloroplasts.  - this is false. Photosynthesis occurs in the chloroplasts, not cellular respiration

It happens in the mitochondria.  - this is true. Respiration occurs in the mitochondria, whereas photosynthesis occurs in the chloroplasts.

It involves oxygen, glucose, carbon dioxide, and water. - this is false, Both photosynthesis and cellular respiration involve oxygen, glucose, carbon dioxide, and water. Photosynthesis produces oxygen and glucose using carbon dioxide and water. Respiration produces glucose and carbon dioxide using water and carbon dioxide.

Several biology students are counting kernels in an ear of corn. They count a total of 420 kernels: 242 purple wrinkled, 84 purp
s2008m [1.1K]
The answer is C) 9:3:3:1

This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth

Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24

We have 
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
