Answer:

2. is caused by reduced gene flow

Explanation:

Speciation occurs when living organisms develop distinct and unique characteristics due to evolution.

Speciation occurs due geographic migration or movement of species of organisms from one place to another. These species become geographical isolated from each other thereby causing a reduction of gene flow amongst them due to an absence of reproduction.

When these separated species get to their new location , they adapt to the new environment and become distinct species.

We have different types of speciation and they are :

a. Allopatric Speciation

b. Parapatric Speciation

c. Sympatric Speciation

d. Peripatric Speciation

The sympathetic chain contains a group of cell bodies called the sympathetic chain Blank 1. Fill in the blank, read surrounding

lions [1.4K]

Answer:

The sympathetic chain contains a group of cell bodies called the sympathetic chain GANGLIA. This structure contains a second cell body for the sympathetic nervous system, the first in the series being found in the THORACOLUMBAR REGIONS' lateral horn of spinal segments T1-L2. The purpose of the VENTRAL AND DORSAL rami is to carry visceral motor and visceral sensory neurons to and from this sympathetic chain.

Explanation:

The sympathetic trunks (sympathetic chain, gangliated cord) are a paired bundle of nerve fibers that run from the base of the skull to the coccyx.

What is the oxidizing agent in the following reaction?

Andru [333]

Answer:

The answer is d. pyruvate

Explanation:

An oxidizing agent is the substance that gains electrons in a chemical reaction. At the end of the reaction it is reduced and its oxidation state increased.

A reducing agent is the substance that loses electrons in a chemical reaction. At the end of the reaction it is oxidized and its oxidation state decreased.

Pyruvate gains one electron, it is reduced from pyruvate to lactate; thus, pyruvate is the oxidizing agent.

NADH loses one electron, it is oxidized from NADH to NAD; thus, NADH is the reducing agent
