Antimycin A Antimycin A is used in catfish farming: added to the water at 10 ppb, it kills small fish but does not harm catfish. Thus, small fish die out, and catfish get all the resources. When Antimycin A is added to isolated mitochondria, NADH and succinate both accumulate. However, if ascorbate, an artificial redox mediator that transfers electrons to cytochrome c, is added, oxygen consumption is still observed. Which step in the respiratory chain is antimycin A likely to inhibit (1 pt)
Answer:
Inhibits electron transport chain in mitochondria.
Explanation:
Antimycin A inhibits electron transport chain which leads to the complete halt of electron transport in mitochondria. due to this inhibition of electron transport chain in mitochondria leads to the killing of the fishes except catfish and so the catfish increase in population due to more resources and no competition. this Antimycin A is highly toxic for fishes and kill all fishes if used at the amount of 10 ppb.
Megalodon left an awful lot of teeth behind, but don't worry. It is likely that it had plenty of extras. Like modern sharks, Megalodon had several rows of teeth. Scientists believe that Megalodon had six rows of 7-inch-wide, razor-sharp teeth, top and bottom, for a total of 276 teeth in its giant jaws! It's no wonder, then, that this ancient shark left so many of them behind. Without this trail of teeth, we would not know that these enormous creatures swam the ancient oceans as a top predator.Select two sentences from below that best show that the author wants the reader to be able to relate Megalodon's size to everyday life
A.What would you expect a creature whose name means “big tooth” to look like?
B.The Megalodon shark deserves this title.
C.As the Greek roots mega- (“big”) and don (“tooth”) suggest, this awesome prehistoric creature certainly did have huge teeth—as well as a massive and powerful body.
D.Scientists estimate that these gigantic sharks stretched as long as 60 feet.
E.If you're having trouble imagining that, just think of a school bus, typically about 45 feet in length.
F.Now, imagine a shark just a bit larger than that school bus—with 7-inch teeth.
G.Yes, this ancient fish certainly earned the prefix mega!
H.Since these sharks are extinct, how do we know exactly how huge and powerful the Megalodon shark was?

PLEASE HELP ME WITH 10 and 11!! :(
Answer:
Please find the answers to numbers 10 and 11 of the attached image below.
Explanation:
10. This question lists the stages of mitosis namely: prophase, metaphase, anaphase, and telophase. The major events that take place in each of these stages are as follows:
A) PROPHASE:
- the supercoiled chromosomes known as chromatin begins to condense making it visible.
- spindle begins to emerge from the centrosome organelle.
- Nuclear envelope begins to break down in order to expose the chromosomes in the nucleus.
B) METAPHASE:
- The chromosome are aligned at the cell plate i.e. the equator/middle of the cell.
C) ANAPHASE:
- The sister chromatids of each chromosome i.e. replicated chromosomes are pulled apart at the centromere by spindle microtubules to the opposite poles of the cell.
D) TELOPHASE:
- Chromosomes at opposite poles begin to decondense into chromatin.
- The nuclear envelope reforms around the chromosomes
11) Cytokinesis is the process that occurs after mitosis (nuclear division). It is the process whereby the cell whose chromosomes are now separated into opposite poles divide into two. In other words, a cell divides into two in the cytokinesis stage.
Which of the following best describes the role of water in photosynthesis?
Answer: During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Explanation:
The question is incomplete, the options is gotten from another website.
Here are the options.
Water Is the only source ofprotons for the formatlon of & proton gradlent Water molecules donate elecirons to the electron transport chaln: Water molecules combine wlth stored carbon molecules t0 produce glucose Water Is the terminal electron acceptor for electrons that pass through the electron transport chain;Water molecules combine wlth stored carbon molecules to produce glucose best describe the Role of water
What is Photosynthesis?Photosynthesis is the process where gree plants uses light energy from sun with carbon dioxide to produce glucose and water in the presence of chlorophyll.
What is the Role of water in Photosynthesis?Six molecules of water react with six molecules of carbon molecules to produce glucose.
It form chemical potential around membrane which help in the production of energy.

Fossils or organisms that show the intermediate states between an ancestral form and that of its descendants are referred to as transitional forms. There are numerous examples of transitional forms in the fossil record, providing an abundance of evidence for change over time.
Monomers linked together to form a polymer could be described as beads in a multicolored necklace. Which statement about monomers is true with respect to the above analogy?
A. Monomers in a polymer could be linked in various ways.
B. Monomers in a polymer are of different types.
C. Monomers in a polymer look different but are structurally similar.
In a plant, leaf color and leaf shape are controlled by two linked genes. Leaves of the wild plant are red (R) while a recessive mutation in this gene causes leaves to be white (r). Wild-type leaves are pointed (P), while a recessive mutation in this gene causes them to be smooth (p). For a parent plant that is heterozygous for both traits with both recessive mutations on one chromosome, what genotypes will its gametes be

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals (RR), 257 brown sided individuals (Re) and 557 tan-sided individuals orr). Calculate the following:_______.
a. What is the allele frequency of the Rallele (o)?
b. What is the allele frequency of the rallele (a)?
Migration season comes and 200 of the red-sided individuals leave the nosulation before mating occurs.
c. After migration season what is the new allele frequency of the Rallele (0)?
d. After migration season, what is the new allele frequency of the rallelelo?
e. Which mechanism of evolution (natural selection, genetic drift, or gene flow) caused the allele frequencies to change?
Answer:
a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1049 / 2420 = 0.433
b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1371 / 2420 = 0.567
c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 649 / 2020 = 0.321
d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 1371 / 2020 = 0.679
e) migration is gene flow
Explanation:
Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).

Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
