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

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.

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

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices

Answers

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.  

Postzygotic mechanisms or barriers include

Hybrid inviability,   Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

What is responsible for the red tide phenomenon? It is a phenomenon that usually coincides with storm surges; the name comes from the red kelp that often washes ashore as a result of rough weather. Red tide occurs in patches of water where certain species of dinoflagellates flourish. They are so abundant that the water becomes discolored and takes on a red hue. Red tides occur once a year and in accordance with the lunar cycle. The water appears red as a result of reduced levels of photosynthetic pigmen

Answers

Answer:

Red tide occurs in patches of water where certain species of dinoflagellates flourish.

Explanation:  

Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.

Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.

Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.
