,

• Sedimentary rocks are formed by the accumulation

A researcher collects what appears to be a new species in a freshwater stream. Microscopic analysis shows the presence of chloro
algol [13]

According to the research, this new species most likely belongs to the Protista kingdom since it has a defined nucleus.

<h3>What is the Protista kingdom?</h3>

They are unicellular or multicellular microorganisms that, for the most part, feed autotrophically, and that, on the other hand, cannot be included in the remaining three kingdoms of eukaryotes.

It can be both autotrophic and heterotrophic by photosynthesis, although many of them combine both forms of nutrition and have chloroplasts, mitochondria, a defined nucleus, among other structures.

Therefore, we can conclude that according to the research, this new species most likely belongs to the Protista kingdom since it has a defined nucleus.

The diagram shows a bacterial cell dividing. What is an ADVANTAGE of this type of reproduction?
Naddika [18.5K]
(Sorry if this is late)

The answer to this is B because it is the only answer choice that is true.

This is actually a quick process, making A incorrect.

C is incorrect because there are no different genes to combine with, since there is only ONE parent cell.

D is incorrect because the offspring are clones. They haven't adapted at all.

Have an awesome day! :)

A person is told to take 1.25 mg of vitamin d daily. how many 0.125-mg tablets should this person take?
vovikov84 [41]
This is a simple calculation involving drug doses.

The solution is as follows:

(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets

So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.

alexandr402 [8]

Answer:

The correct option is D.

Explanation: The options attached to this question are given below:

A) Bacteria from other animals replace those killed by the antibiotics.

B) The few surviving bacteria that are affected by the antibiotics develop immunity to the antibiotics, which they pass on to their progeny.

C) The antibiotics cause new mutations to occur in the surviving bacteria, which results in resistance to antibiotics.  

D) The antibiotics kill susceptible bacteria, but the few that are naturally resistant live and reproduce, and their progeny repopulate the host animal.

E) The antibiotics persist in soil and water.

Antibiotics are sometimes used in animals to control infections. With time, the microbes that are been targeted with the antibiotics usually develop mutations, which makes the antibiotics to become ineffective, thus, the antibiotics will only be able to kill the susceptible microbes while the ones that have developed resistance will remain and give birth to young ones that are also resistant to antibiotics.
