Answer:
one common ancestor
Explanation:
Although Darwin’s theory is often described as the theory of evolution by natural selection, most commentators recognize that common ancestry (the idea that all organisms now alive on earth and all present day fossils trace back to one or a few “original progenitors”) is an important part of the Darwinian picture.
Answer:
A basic and a non-invasive test done in pregnancies during the course of 28 weeks of gestation is termed as a fetal non-stress test. It is termed non-stress as no stress is imparted on the fetus while performing the examination. The main objective of the test is to determine the fetus's heart rate at the time of its movement.
In the test, it can be seen that the heart rate of the fetus gets increased each time it moves, which shows that the baby is healthy as the heart rate goes up when it moves and goes down during its resting stage. The principle behind the test is that for proper well-being of the fetus, sufficient oxygen is needed and heart rate should come in normal ranges.
B.
Homogeneous means one mixture, so like salt water. It looks like one mixture.
Heterogenous means different mixture. Comparable to a bag of Chex mix. So if the magnet can attract the pieces of Iron, it has to be a separable mixture. Compounds would require a chemical reaction to separate.

<u>Aerobic </u><u>respiration </u>:- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen
<u>That </u><u>is</u><u>, </u>
<u>Aerobic </u><u>respiration </u><u>is </u><u>takes </u><u>place </u><u>in </u><u>four </u><u>stages </u><u>:</u><u>-</u>
- <u>Glycolysis</u>
- <u>The </u><u>link </u><u>reaction </u>
- <u>The </u><u>Krebs </u><u>cycle </u>
- <u>Oxidative </u><u>phosphorylation </u>
In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.
<h3><u>Whereas</u><u>, </u></h3>
<u>Anaerobic </u><u>respiration </u>:- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen
The end products of glucose in anaerobic respiration is
- <u>In </u><u>human </u><u>muscles</u><u>, </u><u> </u><u>Lactic </u><u>acid </u><u>+</u><u> </u><u>Energy </u>
- <u>In </u><u>yeast</u><u>, </u><u>Ethanol </u><u>+</u><u> </u><u>CO2</u><u> </u><u>+</u><u> </u><u>Energy </u>

Answer:
lava flows are very hot, thin and runny. When it cools is has a smooth to ropey texture because of the low silica content which makes it cool quickly. Pahoehoe flows creep along generally at less than 3 feet per minute but some flows have been measured at over 20 miles per hour.

it is A
