A conservation ecologist is studying Pacific Green Sea Turtles. One population is based on a remote island in the Indo-pacific that has very little tourist or human activity. The other population is on the coast of Australia and deals with more consequences of human activity. The ecologist has taken counts of the number of eggs in each female’s nest at both locations to evaluate the reproductive success. Is there a statistically significant difference between the two populations? What conclusion can you draw from this information? (5 points, 2 for answer, and 3 for showing work)

Answers

Answer:

Yes.

Explanation:

Yes, there is a statistically significant difference between the two populations of green sea turtle because the turtle lay eggs on the beaches of the ocean so human presence at the beach damaged eggs and lead to the decrease in population of green sea turtle while on the other hand, there is high population of green sea turtle due to no human presence or activities in the remote Island.

Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test results from a person done after 2 hours of drinking a lactose rich solution. The blood glucose levels were 80, 110, 140 and 160 mg / dL tested for every 30 minutes. Based on this information does this person have lactose intolerance?

Answers

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.

If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?

A The climate would get colder and drier as you go up the mountain.
B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.

Answers

Answer:
C
Explanation:
It’s easy

The climate would get colder and drier as we go up the mountain. So, the correct option is A.

What is the effect of altitude on the atmosphere?

When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.

Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.

Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.

Answers

Answer:

The codons that code for LEUCINE amino acid are:

1. UUA

2. UUG

3. CUU

4. CUC

5. CUA

6. CUG

Explanation:

A CODON is a group of three nucleotides in the mRNA molecule that specifies a particular amino acid. It represents a trio combination of nucleotides (A, G, C, U). There are about 64 possible codons formed from four nucleotides used in a combination of three's i.e 4³ = 64. All the codons collectively form the GENETIC CODE, which is used by all known living organisms.

However, since there are only 20 amino acids in nature and 64 possible codons, more than one codon encodes an amino acid. This means that the genetic code is DEGENERATE or REDUNDANT. Hence, in this case involving the amino acid: LEUCINE, the six (6) codons that specify it (depicted in the attached genetic code) are as follows:

- UUA

- UUG

- CUU

- CUC

- CUA

- CUG

A codon is a three nucleotidic sequence that carries genetic information to assembly an amino acid to the growing protein. The six codons that code for leucine are UUA, UUG, CUU, CUC, CUA, and CUG.

----------------------------------------

During translation, the ribosome reads mRNA in 5' to 3' direction. While doing so, tRNA recognizes the codons and adds the correct amino acid to the growing peptidic chain.

A codon is a three nucleotidic sequence that carries genetic information to assembly an amino acid. One codon determines which amino acid is going to be addede to the protein.

In nature, thete are 20 amino acids that compose the proteins, and more than 20 possible codons combinations. So one amino acid is coded by more than one codon.

The amino acid LEUCINE is coded by six codons. They are,

Answer and I will give you brainiliest

Answers

sorry im not sure this is correct but i think the one that is incorrect is

4) the right side of the heart receivesblood and the left side pumps blood.

i will put the explanation just incase you want to choose the answer by yourself after knowing it. I hope you read this too..

Explanation

1)Blood flows in two loops

This one is already correct if it happens in human heart circulatory system. Human's heart beat in two loops and this is really useful because of enough pressure to pump blood to the body. This two loops name is double circulatory system.However fish has single circulatory system where they only pump blood once. So this one also can be wrong but if the answer only one, this one can pass.

2)the ventricles contract simultaneously to pump blood outside the heart.[✓]

This one already correct, the heart pump blood to the body through aorta and to the lungs through pulmonary artery.

3)blood flows simultaneously into the atria.

This one also correct, because the blood come to the atria first to go to the left ventricle. Both of left and right ventricles are working simultaneously.

4)the right side of the heart receives

blood and the left side pumps blood.

This one can be correct but also wrong. I choose this one wrong because there's no more explanation in this statement. The right side of heart can also pumps blood and left side of heart also can receives blood.The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs and also The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
