Which is allopatric and which is sympatric

Biology
1 answer:
Helen [10]3 years ago
4 0

Answer: The correct answer is-

Allopatric-  option 2.

Sympatric - option 1.

Allopatric and sympatric are primarily the two major mechanisms for  speciation ( formation of new species from an ancestral species).

In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.

On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.

Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.

7. What do fruits do for the seed? *
Nikolay [14]
The function of a fruit with seeds is seed dispersal. There's no way a fruit could disperse seeds, if it didn't actually have a seed or seeds at some point. Fruits develop from the ripened ovaries of plants, once the ovule (egg) or ovules inside the ovary has been fertilized.

Answer: Sympathetic Nervous System.

Explanation:

The sympathetic nervous system is part of the autonomic nervous system. The sympathetic nervous system activates what is often termed the fight or flight response. The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles. Breathing quickens, delivering fresh oxygen to the brain, and an infusion of glucose is shot into the bloodstream for a quick energy boost. The sympathetic nervous system allows animals to make quick internal adjustments and react without having to think about it.

natima [27]

Answer:

It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)

Explanation:

The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
