5 0

Answer;

-The statements that are true of Pangea include;

A. Pangaea was one of several supercontinents that have formed and broken up during Earth's history.

C. Rates of seafloor spreading in the Atlantic Ocean are compatible with what is known about the breakup of Pangaea.

D. The regional-scale folds visible in the Appalachian Mountains are remnants of Pangaea's formation.

Explanation;

-About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa.

-The movement of Earth's tectonic plates formed Pangaea and ultimately broke it apart. Pangaea existed during the Permian and Triassic geological time periods, which were times of great change.

Answer:

Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

Which of these blood samples most likely came from the left ventricle?
PilotLPTM [1.2K]
Sample A most likely came from the left ventricle, as this is the portion of the heart that receives freshly oxygenated blood to be pumped to different parts of the body. Oxygenated blood is blood that has had oxygen bounded to it by hemoglobin (a pigment made of iron found in red blood cells). The oxidation of this blood by the iron in the hemoglobin gives it the RBC bright red look. This blood containing the bright RBCs in transported to the left ventricle from the lung, after which it is spread throughout the body. Hence, in normal conditions of the heart, the Sample A most likely came from the left ventricle.

A mutant strain of yeast is able to produce 2 ATP for each glucose molecule digested in the absence of oxygen. What makes this s
Free_Kalibri [48]

Answer:

Explanation:

Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.

pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD

The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.

If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme.   <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.

Where is amyglada located in a brain ? How does it function ?​
Sedbober [7]

Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.

Explanation

The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

Digestion begins in the mouth with the process of chewing also known as mastication. Saliva in the mouth mixes with the food. saliva contains amylose. This breaks down sugar into smaller units of dextrins and maltose.

In the small intestine, the pancreas releases pancreatic juice which breaks down dextrins into smaller units.

the cells in the small intestine helps to transport the digested nutrients to the blood stream

Undigested food goes to the large intestine and eliminated in the stool
