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

Extend your thinking: Biological evolution is the process by which populations of organisms change over time. How could natural selection lead to evolution?
Explanation:
Natural selection is a process where organisms that are better adapted to an environment will survive and reproduce. This means that the advantageous alleles of this variant organism are passed on to offspring. Over many generations, the process of natural selection leads to evolution occurring.
Environments change over time, and natural selection acts on the genetic diversity in species. After many generations in this new environment, the current population may not look like their ancestors because natural selection has changed them – they have evolved – to survive in the new environment
Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth
Natural selection could lead to evolution when mutated genes are passed on from parents to offsprings over time. Details about evolution can be found below.
What is natural selection?Natural selection is a biological process by which living organisms become better adapted and suited for survival and reproduction.
Natural selection occurs in living organisms and over time leads to the evolutionary process.
Therefore, it can be said that natural selection could lead to evolution when mutated genes are passed on from parents to offsprings over time.

Explanation:a
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.

Why must an owl
swallow its prey whole?
Answer:
Owls swallow their prey whole or in large pieces but do not produce enough stomach acid to digest bones, fur, feathers and scales. Because undigested body parts could injure the owl’s intestine, the animal needs another way to deal with that part of its diet. That’s where owl pellets come in. An owl has two stomachs. Most birds can’t chew their food, and owls are no exception. Owls usually swallow their prey whole; they differ from other species of birds because they don't have a crop, the baglike organ used to store food after it has been swallowed so that it can be digested later

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
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.
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

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.

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.

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.
