A certain species of salamander was split into two populations by a wide, dry valley, and the populations began to diverge from

olya-2409 [2.1K]

Answer:

This outcome in a hybrid zone is known as <u><em>fusion</em></u>.

Explanation:

In the field of biology, hybrid zone can be described as the area where closely-related species can interbreed and produce hybrid organisms. Reinforcement can be described as the phenomenon by which a hybrid zone develops between full species barriers. Hybrid speciation can be described as the phenomenon by which a new species forms as the direct result of mating between members of two existing species.

Imagine that zika virus has a 1% incidence in the population. A test for the virus has a 3% false positive rate and no false neg

Darina [25.2K]

Answer:

The answer is 97%.

Explanation:

The zika virus' 1% incidence rate in the population has no effect over the probability of the patient being infected or not. If the test has a 3% false positive rate that means that if it is positive, the results have a 97% chance of being true. Therefore the chance that the person who took the test and had a positive result being actually infected is 97%.

I hope this answer helps.

Why do rice plants include starch and protein in their seeds

Wittaler [7]

A single gene could be inserted into a plant's genome, enabling specific traits to be expressed easily. Scientists have identified genes for two enzymes needed to make pro-vitamin A. One of these genes comes from corn.

Cellular respiration map

nexus9112 [7]

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)

The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

plz help!!! If this is a sequence of one DNA strand, what is the complementary sequence of the other DNA strand? DNA: A T T C A

gizmo_the_mogwai [7]

Answer:

T A A G T C G C T

Explanation:

DNA strand: A T T C A G C G A

complementary DNA strand: T A A G T C G C T

This is a very important rule:

Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)

And this is how they're coupled:

A = T

C = G

For example::

First DNA strand: A T G C

complementary strand: T A C G
