Answer:
True
Explanation:
2) The slight negative charge at one end of a water molecule is attracted to the slight
positive charge of second water molecule. What is this attraction/bond called?
A) a covalent bond
B) a hydrogen bond
C) an ionic bond
D) a hydrophilic bond
E) a hydrophobic bond
3) What gives rise to the cohesiveness of water molecules?
A) hydrophobic interactions
B) nonpolar covalent bonds
C) ionic bonds
D) hydrogen bonds
E) both A and C
Answer:
2. C
3. D
Explanation:
2. Ionic bonds are chemical bonds that forms between the ions of molecules or compounds. The two molecules are joined together by an electrostatic force. This is the case of the bond that forms between the slight negative charge (anion) at one end of a water molecule and the slight positive charge (cation) of a second water molecule.
3. Cohesion refers to the attraction of a molecule to a like molecule. The cohesiveness of water molecule to another water molecule is great due to the HYDROGEN BONDS that forms between them.

Which of the following explains what is happening to the fish population due to the increase in human population?
People are switching to eating more meat Instead, which is increasing the fish supplies.
People are still eating plenty of fish and there are more people, so the supply is being depleted faster.
People are reducing fish consumption as the population increases, so fish are being depleted at a slower rate.
People are eating more fish despite the increase in the population, so the fish supply is being privately farmed.
Answer:
People are eating more fish despite the increase in the population, so the fish supply is being privately farmed.
why do our digestive systems produce separate enzymes to digest proteins, fats, and carbohydrates?
Answer:
The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.
Explanation:
Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.
There are different enzymes, produced in the digestive system, for this purpose:
Proteases degrade meat proteins to convert them into amino acids. Lipases convert fats into fatty acids. Amylases convert sugars and carbohydrates into glucose.The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.
Today, we push economies to grow whether or not they make us thrive. Especially in the richest countries, we should strive for economies that make us
thrive whether or not they grow." What type of economic model does this statement represent?
A. Classical economics
B. Threshold economics
C. Supply-side economics
D. Doughnut Economic Model
Answer:
D. Doughnut Economic Model
Explanation:
The "Doughnut Economic Model" is focused on the benefits that people can get in its economy rather than its growth. This situation is also known as the "circular economy," which deems thriving as more important than growing. The doughnut is represented by different things. The middle hole refers to the poor people in the society. The inner ring refers to the things we need in order to thrive in life while the dough refers the the area where people meet their needs. All of these interact within a circle, thus the term circular economy.
Oncogenes are mutated forms of genes. Oncogenes can transform a normal cell into a tumor
cell. Some tumor cells are benign, while others are malignant. How does the presence of an
oncogene lead to the formation of a tumor? option choices
F ATP production is inhibited.
G Somatic cell growth is inhibited.
H Cell division is unregulated.
J Antibody activity is unregulated
Answer:
H Cell division is unregulated.
Explanation:
Oncogenes are genes that, when mutated or somehow rendered overactive, cause cells to proliferate uncontrollably. This is a hallmark of cancer.
These genes make proteins with a range of functions, for example, signalling proteins, enzymes, transcription factors. What they have in common is that they promote cell growth and division.
when the phases of the moon are getting larger, it is to be ?
Answer:
The moon is 180 degrees from the sun. When the bright part is getting bigger, the Moon is waxing. When it is getting smaller, the Moon is waning. When the Moon is more than half-lit, it is called a gibbous Moon.
Explanation:
The experiment was set up to test the hypothesis that plants grow faster in green light. The same amount of water and fertilizer were added to each pot. Which action would improve the experiment?
A use different parts
B add more types of plants
C use plant food
D use the Same kind of plants in all trials.
Answer: B
Explanation: If you use the same plants then you can't see if this plant or that plant is better at growing in green light. If you add different plants it will make it more interesting. The best answer is B

Why do you think poikilothermic (cold blooded) animals are
slowed down by low temperatures?
Poikilothermic (cold blooded) animals are slowed down by low temperatures because all chemical reactions slow down as the temperature is lowered, so at low temperatures, all the chemical reactions in an organism slow down.

Explanation:
if you wanted to test red blood cells for their ability to complete glycolysis, what compound would you try to detect
Answer:
Pyruvate
Explanation:
Glycolysis refers to the pathway through glucose is oxidized to pyruvate.
In glycolysis, a molecule of glucose passes through ten enzyme catalyzed steps to yield two molecules of pyruvate.
Step 1: Glucose is phosphorylated to form glucose-6-phosphate
Step 2: Glucose-6-phosphate is converted to fructose-6-phosphate
Step 3: Fructose-6-phosphate is further phosphorylated to form fructose-1,6-bisphosphate
Step 4: Fructose-1,6-bisphosphate is cleaved into glyceraldehyde-3-phosphate and dihydroxyacetone phosphate
Step 5: Dihydroxyacetone phosphate is converted to another molecule of glyceraldehyde-3-phosphate.
Step 6: Two molecules of Glyceraldehyde-3-phosphate are converted to two molecules of 1,3-bisphosphoglycerate
Step 7: Two molecules of 1,3-bisphosphoglycerate are converted to 3-phosphoglycerate
Step 8: Two molecules of 3-phosphoglycerate are converted to two molecules of 2-phosphoglycerate
Step 9: Two molecules of 2-phosphoglycerate are converted to two molecules of phosphoenolpyruvate
Step 10: Two molecules of phosphoenolpyruvate are converted to two molecules of pyruvate, the end-product of glycolysis.
Therefore, the presence of pyruvate molecules in red blood cells can be used to test for their ability to complete glycolysis
Plato's allegory of the cave indicates that
majority opinion is almost always correct.
truths about reality are not always obvious.
when we seek the truth, we must always trust our senses.
imagination is a more reliable guide than objective reality?
Answer:
truths about reality are not always obvious.
Explanation:
Plato's allegory of the cave was proposed by the Greek philosopher called Plato. This was used to emphasize the importance of education and the effect caused by a lack of it.
Plato's allegory of the cave indicates that truths about reality are not always obvious. This implies that no matter how real something seems to be it is always ideal to ask questions about it which is useful in problem solving.

Muscle cells contract using ATP. There is little ATP in your blood stream. How do your muscle cells get ATP they need to contract and move you?
1. ADP enters the cells from the bloodstream and it turns into ATP by adding a phosphate group in the nucleus
2. glucose from the bloodstream enters the cells and the mitochondria turns it into ATP
3. amino acids in the muscle tissue are broken down into ATP in the nucleus
4. glycogen from the bloodstream is turned directly into ATP by using enzyme glycanase

How are the enzymes that nerve cells produce different from the enzymes that blood cells produce? A. The molecules that nerve cells digest are more complex than those digested by blood cells. B. The genes that are activated in nerve cells are different from those activated in blood cells. C. Nerve cells contain more ribosomes than blood cells. D. Nerve cells contain more mitochondria than blood cells.
Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.
