The graph shows the supply and consumption of forests when the
consumption rate and population growth rate are both low.
When does consumption begin to surpass supply?

Answers

Answer:

In about 625years

Explanation:

According to the graphical representation depicted in this question, it shows the supply and consumption of forests when the consumption rate and population growth rate are both low. The green line represents the total consumption while the red line represents the total supply.

Based on observation of the graph, the total consumption exceeds or surpasses the total supply at a little above 600 years. Approximately, this can be said to be in about 625years.

Answer:

In about 625 years

Explanation:

Consumption has definitely surpassed supply by 700 years, but it only begins to surpass it around the 625 year mark according to the graph

It is believed that the ratio of cyclic electron transport to Z-scheme photosynthesis changes in response to metabolic demands. If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, how would it alter these processes compared to a plant just performing the Calvin cycle to produce glucose

Answers

Answer:

The correct answer is (b) More Z-scheme photosynthesis, less cyclic photophosphorylation

Explanation:

Z-scheme is the schematic flow of the electrons from water to NADP+ and as it connects the two different photosystems that look like z in the diagram it is termed as Z-scheme of photosynthesis. The ratio of cyclic electron transport to Z-scheme photosynthesis alters as per the metabolic requirements. In the question, it is given that If a plant were actively engaged in a large amount of reductive biosynthesis, requiring NADPH, then it will acqiuire more z-scheme photosynthesis compared to a plant just performing the Calvin cycle to produce glucose.

Answer:  More Z-scheme photosynthesis, less cyclic photophosphorylation

Not sure if it’s right

Explain how a person can be a carrier for a sex-linked disorder, but not exhibit this disorder.

Answers

It comes down to genes it can be passed down from family

A person cannot exhibit the disorder because they don't experience the condition because they have a healthy copy of the gene on their other sex chromosome.

A disorder is a functional abnormality or disturbance that affects an individual's physical, mental, or emotional health.

They have the potential to pass on the mutated gene to their offspring, but they do not exhibit the disorder themselves because they have a normal copy of the gene on their other sex chromosome.

In the case of X-linked disorders, females have two X chromosomes, while males have one X chromosome and one Y chromosome. Females can be carriers for X-linked disorders if they inherit one mutated X chromosome from one parent, and one normal X chromosome from the other parent.

Males, on the other hand, cannot be carriers of X-linked disorders because they only have one X chromosome.

Therefore, a person can be a carrier for a sex-linked disorder if they have one copy of a mutated gene on one of their sex chromosomes, but not on both.

How do we make a new gene

Answers

Answer:

Well to make a new gene, theoretically you would need to mutate your DNA of some sort.

Explanation:

Genes  come naturally from your parents. And if you want a new gene that you can say "control" like being tall or having a high/low metabolism, you would have to rearrange or "mess around" with your DNA.

Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.

Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.
(E) Five of the fish species native to the Emerald River are not native to any other river in North America.

ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.

Answers

Answer:

A

Explanation:

the sister chromatids separate

After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.

What is Homologous pair?

Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.

In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.

This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.

Therefore, the correct option for this question is A.
