The answer is: Those bacteria may contain genes that will help convert plant material to ethanol. Hope this helps!!! :)

Some scientists are studying the bacteria that live in the guts of termites because those bacteria may contain genes that help convert plant material to ethanol.

Termites are a type of insect that belongs to the order Isoptera. They are commonly known as white ants but they are not closely related to true ants. They are social insects and live in colonies or nests.

Termites are able to break down the cellulose in wood and other plant materials, which is a process that has potential applications in biofuel production. The bacteria that live in the termites' gut play an important role in this process by producing enzymes that help to break down the cellulose. Scientists are interested in studying these bacteria to learn more about the enzymes they produce and how they can be used to convert plant material into ethanol more efficiently.

Answer:

A. The hydrogen atoms have a partial positive charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge.

Explanation:

I just took the quiz. That was the correct answer.

The hydrogen atoms have a partial positive charge and are attracted to the oxygen atom in another molecule, which has a partial negative charge. The correct option is A.

A hydrogen bond or H-bond is an electrostatic attraction between a hydrogen atom covalently bound to a more electronegative "donor" atom or group.

Another electronegative atom weighing down a lone pair of electrons the hydrogen bond acceptor.

Since the electron is not shared evenly between a hydrogen atom and a negatively charged atom, hydrogen bonding occurs.

Hydrogen in a bond still has one electron, whereas a stable electron pair requires two electrons.

Hydrogen bonds form between adjoining hydrogen and oxygen atoms of adjacent water molecules in the case of water. A hydrogen bond is formed by the attraction of individual water molecules.

Thus, the correct option is A.

Answer:

Diffusion will continue until the concentration gradient has been eliminated. Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop. At equilibrium, there is equal movement of materials in both directions.

Answer:

Only the strongest would survive each year and be able to breed

Explanation:

According to Darwin's theory of evolution if an animal were to be put into terrain whether local or new, the animal would need to adapt as its surrounding slowly change. If said animal is unable to adapt in time it will perish or be unable to produce strong offspring that will survive.

Answer: $19,866

Explanation:

We know that the initial investment is $6,000. And it doubles every 11 years.

Then after 11 years, the amount of money will be 2*$6,000

After another 11 years (a total of 22) the amount of money will be 2*(2*$6,000)

or $6,000*(2)^2

We already can see that this is an exponential growth equation.

After n times 11 years, the amount of money will be;

M = $6,000*(2)^n

But n represents groups of 11 years, then if y represents the number of single years, we can write the equation as:

M = $6,000*(2)^(y/11)

You can see that y = 11 is equivalent to n = 1

y = 22 is equivalent to n = 2

and so on.

Then the equation:

M = $6,000*(2)^(y/11)

Tell us how much money will be in the account after y years.

Now we only need to replace y by 19, to get:

M = $6,000*(2)^(19/11) = $19,866

Where i rounded the amount of money to the nearest dollar.

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.

Answer:

cosθ = 3/5

Explanation:

Given that,

sinθ = 4/5

We need to find the value of cosθ.

We know that,

sinθ = P/H

Where

P is perpendicular and H is Hypotenuse

Using Pythagoras theorem to find base (b).

H²=P²+B², b is base

We have, H = 5, P = 4, B=?

b²=5²-4²

b=3

We know that, cosθ = B/H

Putting all the values,

cosθ = 3/5

Hence, the correct option is (b) "cosθ = 3/5".

Answer:

Revolutions do share common features, however. One is that they are fast-moving. In a short time, often just a few years, a revolution can bring about significant change and upheaval. Most revolutions are driven by people and groups inspired by hope, idealism and dreams of a better society.

Answer:

Lipophilic (non-polar molecules), such as steroid hormones or O2 gas can pass... very small uncharged polar molecules (such as H2O, ethanol and urea) can also get through... otherwise you need a membrane protein to "facilitate" the transport of the molecule across the membrane, ion channels are used for water, or charged molecules; carriers/transporters are used for other molecules.

Answer:

2. Hip bones

Explanation:

More than 40 million years ago, whales had ancestors who walked on land. Even now, they have a feature they inherited from them - hip bones. Scientists used to think that they are vestigial, i.e. that they lost their function. However, recently they discovered that these bones help whales (and other marine mammals who have them, such as dolphins) maneuver better mating.

Whales developed the rest of the listed features later, when they became marine animals. This is why they are incorrect.
