Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.

Answer:

[tex]C(t) = C_oe^{-kt}[/tex]

Explanation:

From the given information:

At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.

Deriving the equation:

[tex]\dfrac{dC}{dt}[/tex] decrease proportionally to Concentration C

i.e

[tex]\dfrac{dc}{dt} \alpha - C[/tex]

[tex]\dfrac{dc}{dt} = -k C[/tex]

[tex]\dfrac{dc}{c} = -k dt[/tex]

[tex]\int \dfrac{dc}{c} = -k \int dt[/tex]

㏑(C) = -kt + λ

where,

λ is the integration constant.

Integrating at t = 0, concentration of blood = Co g/mL

C(0) = Co

㏑(C₀) = 0 + λ

λ = ㏑(C₀)

From ㏑(C) = -kt + λ

㏑(C) = -kt + ㏑C₀

㏑(C)  - ㏑C₀ =  -kt

[tex]\dfrac{C}{C_o} = e^{-kt}[/tex]

[tex]C(t) = C_oe^{-kt}[/tex]

∴

The concentration of drug in blood at any time t is:

[tex]C(t) = C_oe^{-kt}[/tex]

Answer:

C

Explanation:

So, there are 2 different forms that DNA can be found in.

The more common form, where the DNA is loosly scattered.

There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.

In the case of chromosomes, DNA is tightly pakced, and not loose.

Now, do they are do they  not have protiens?

Well, heres another question, how does the DNA get compacted?

It has to wrap around histone protiens.

The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.

So to answer the question, yes, there are protiens found in chromosomes(specificly histone).

This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

Fat cells burn energy quickly when other food source is available, so being expandable would help with the rapid burn.

The relationship between the expandability of fat cells and a fat cell's function is ; ( A )  Fat cells store energy for the body to use later, so being expandable would help with storage.

Fat cells specialized for the storage of energy in human body is the Adipose tissue which can expand between 60 to 70% of the weight of the human body in response to changes in the energy balance of the body.

Adipose tissues store energy in form of triglycerides and in order to store more energy for later use the Adipose would need to be expandable to accommodate the required amount of energy.

Hence we can conclude that the relationship between the expandability of fat cells and a fat cells' function is Fat cells store energy for the body to use later, so being expandable would help with storage.

Explanation:

Offspring that are adapted to a specific environment is the beneficial for the survival of a species.

A species is an organism's fundamental unit of classification, taxonomic rank, and biodiversity. The biggest group of organisms in which any two individuals of the right sexes or mating types can conceive a fertile offspring, usually by sexual reproduction, is referred to as a species.

A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chronospecies idea.

There are between 8 and 8.7 million different species of eukaryotes, according to the most recent accurate estimate.

All species are given a two-part name, or "binomial," with the exception of viruses.

Therefore, Offspring that are adapted to a specific environment is the beneficial for the survival of a species.

Answer:

O 9.25

Explanation:

The following mathematical equation is given in this question:

5x + 2y = 20

Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:

5x + 2y = 20

5 (0.3) + 2y = 20

1.5 + 2y = 20

Collect like terms

2y = 20 - 1.5

2y = 18.5

Divide both sides by 2

y = 18.5/2

y = 9.25

Therefore, y = 9.25 when x = 0.3

Answer:

The correct answer is - it would because both DNA and RNA have 3' OH.

Explanation:

Ammino acid will connect to the tRNA due to the fact that the process of aminoacylation of tRNA when DNA nucleotide is used will perform or act same the mechanism of Class II aminoacyl tRNA synthetase as both DNA and tRNA have 3'OH. This will get the help of  3'OH in the CCA to bond with charged amino acid.

Thus, the correct answer would be - it would because both DNA and RNA have 3' OH.
