A major function of the human urinary bladder is
A) storing urine until it is eliminated
B) releasing urine directly into the bloodstream
C) transforming urine into a nitrogenous waste
D) filtering urine out of the blood

Answers

The answer is A, storing urine until it is eliminated.


The bladder stores urine, allowing urination to be infrequent and controlled. The bladder is lined by layers of muscle tissue that stretch to hold urine. The normal capacity of the bladder is 400-600 mL. During urination, the bladder muscles squeeze, and two sphincters (valves) open to allow urine to flow out.

Answer:

A) storing urine until it is eliminated

Many freshwater plants have adapted to low carbon and light levels by adapting what feature?

Group of answer choices

Carnivorous plants

No need for carbon dioxide

Camouflage

Floating leaves

Answers

Answer:

The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.

Assume that (B) is dominant and (b) is recessive: Bb mates with Bb
A. About 50% of the offspring will show the recessive trait
B. All the offspring will show the dominant trait
C. All the offspring will show the recessive trait
D. About 75% of the offspring will show the dominant trait

Answers

All the offspring will show the recessive trait

If B is dominant over b and Bb mates with Bb, about 75% of the offspring will show the dominant trait.

Looking at the cross:

                    Bb     x     Bb

                   BB   Bb   Bb   bb

BB and Bb will show the dominant trait while only bb will show the recessive trait.

Thus, the chances of the offspring showing the dominant trait would be 3/4 or 75% while the chances of showing the recessive trait would be 1/4 or 25%

c. Mutations are essential for evolution to occur because they produce

variations within a population.

d. Mutations are essential for evolution to occur because they are respo

environmental changes.

Answers

Answer: option C.

Mutations are essential for evolution to occur because they produce variations within a population.

Explanation:

This is because Mutation refer to change in the genetic content or DNA composition of organisms. Therefore , for evolution to occur there must be Mutation because it is the main source of genetic variation or causes genetic variation needed for evolution.

Mutation is important as the basics of evolution because it produce a new DNA sequence for a gene function, which lead to the formation of new allele.

A. During mitosis, mutations occurred and the offspring's DNA stored this information
B. As dogs digested food, mutations occurred which changed the dog's physical appearance.

Answer:

Did humans tame woolly mammoths or other megafauna?

Considering that some people are gifted with handling animals (e.g. horse whisperers), could paleoindians or other Pleistocene peoples have gained the confidence of woolly mammoths or mastodons to use them as transportation and other tasks, the way that Asian elephants are used today?

Fewer resources would be necessary for a human to travel long distances by riding on the back of a woolly mammoth or paleocamel, as the megafauna could graze and get energy. People may also have traveled by boat during late Pleistocene times (the kelp highway along PNW).

How could we test such a hypothesis? Cave art showing a rider on the back of one of the megafauna? A bridle and/or bit? A talisman worn by a camel is known to have been crafted from a meteorite(1), and so talismans or decorations might have adorned the hypothesized woolly steed. Metal was not a known technology during stone tool usage, as far as we know, though.

The New Orleans Musicians' Clinic did not make any recommendations about low or high pitch sounds. Why are high pitch sounds less damaging to ears than louder sounds? Use your model and what you have learned about sound waves and energy to write an explanation. Some helpful words to include in your response are: transfer, energy, eardrum, and air particles.

Answers

Answer:

Due to high energy.

Explanation:

High pitch sounds less damaging to ears than louder sounds because louder sounds contains more energy than high pitch sound. When this high energy of loud sound transfer from air particles towards our eardrum, it can greatly damaged the ear while on the other hand, high pitch sound has low energy so it causes less damaged to the eardrum.

How is antibiotic resistance related to natural selection?

Answers

Answer:

Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Can two different species of fungi from two different genus' mutate into a new species? i just want to know if it's a possibility, and how gigantic or slim the chances are of it happening.

Answers

Answer:

Yes, it is possible.

Explanation:

In this case, I'm guessing you mean breeding.

If that's the case, they will form hybrids.

Between two different species, inter specific hybrids will be formed.

Between two different genus, intergeneric hybrids will be formed.

There's even rare cases of breeding between two families.

So while it is possible for different species and/or genus to breed and form new species, in interspecific breeding for instance, they will have features similar to the parents but turn out sterile.

So to answer your question, it is possible.

It is one of the most important fossils ever discovered. Unlike all living birds, Archaeopteryx had a full set of teeth, a rather flat sternum ("breastbone"), a long, bony tail, gastralia ("belly ribs"), and three claws on the wing which could have still been used to grasp prey (or maybe trees).
