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.
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.

What is a likely consequence of continued human population growth? A. More rain forests B. Fewer urban centers Ο Ο Ο Ο O C. Less pollution D. Depleted natural resources
Answer:
D. Depleted natural resources
Explanation:
If the human population on Earth continues to grow, depletion of natural resources is a very likely consequence.
Especially at the rapid rate that humans consume natural resources, continued population growth would eventually deplete them.
Fossil fuels are an example of natural resources that will eventually deplete, as humans use immense amounts of things like coal and natural gas.
Answer choices A, B, and C are incorrect because they would be consequences of decreased human population growth.
So, the correct answer is D. Depleted natural resources.
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
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
Nitrogen fixation converts nitrogen gas to usable nitrogen for plants?
True
False
Answer:
True, nitrogen fixation converts atmospheric nitrogen into nitrogen that can be used by plants.
Explanation:
Think about water. There's plenty of water on Earth, but very few is actually drinkable, at least for humans. So we have to fix it by filtering out dangerous bacteria in the water and other dangerous stuff before being able to actually drink it. Same with atmospheric nitrogen. It must be "fixed" before plants can actually use them.

A bacterial cell wall is composed of: A) A polysaccharide consisting of a single type of monosaccharide unit and cross-linking oligopeptides. B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides. C) A polysaccharide consisting of 3 types of monosaccharide units and cross-linking oligopeptides. D) Two different polysaccharides and 1 type of oligopeptide, which are cross-linked.
Answer:
B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.
Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.

uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante
Answer:
C
Explanation:
because the plants are farther down lol
Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.
What are fossils?The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.
The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.
The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.
Therefore, option C. the plants existed prior to the Brachiopods.

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They power the electron transport chain.
They power the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They move electrons to the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.

What is a benefit of a plant having Chlorophyll and Carotenoids?
A. The plant can absorb energy from multiple wavelengths at once.
B. They can absorb both sunlight and moonlight .
C. It is not a benefit.
D. If one becomes damaged, the other can take over.
Answer:
Carotenoids have two important functions in plants. First, they can contribute to photosynthesis. They do this by transferring some of the light energy they absorb to chlorophylls, which then use this energy to drive photosynthesis. Second, they can protect plants which are over-exposed to sunlight. but the letter answer I don't know
The benefit of a plant having Chlorophyll and Carotenoids is that plant can absorb energy from multiple wavelengths at once. Option A is the right answer.
What are chlorophyll and carotenoids?Chlorophyll is the green pigment that is responsible for the green color in the leaves of plants. Carotenoid on the other hand is a yellow, orange, and red color pigment that is produced in plants, algae, and some other forms of bacteria.
Chlorophyll actively absorbs light from wavelengths in the range of blue to red.Chlorophyll poorly absorbs light from the green range.Hence, carotenoids absorb light in wavelengths that are ineffective by chlorophyll such as the blue-green range to green range.To learn more about chlorophyll and carotenoids, refer:
