The answer is C as the graph shows a very rapid sudden curve of increased number of individuals unprecedented in previous times.

The answer is C) The population is growing unchecked. It is not A because the population is changing before our very eyes. It is not B because we know that, yet it has nothing to do with the graph. It is not D because it is still goring up even after the carrying capacity. Actually we don't even know what the carrying capacity is because it does not say. Therefore your answer is C.

What types of foods contain reducing sugars?

andreyandreev [35.5K]

A reducing sugar is any sugar that either has an aldehyde group or is capable of forming one in a reaction thru isomerism. The first example that should come to mind is glucose, which can form a <span>β(1→4)</span> linkage. Sucrose, on the otherhand, is a non-reducing sugar. And is bascially the opposite of a reducing sugar. It doesn't form or have aldehydes in a basic environmet.Hope this helps!!

What is meant by the EA of a reaction? How do enzymes affect the EA and the DG of a reaction?

zepelin [54]

Answer:

Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.

The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.

How many types of endocrine systems

mezya [45]

Answer:

There are three types of endocrine cells;

Explanation:

; alpha cells which secrete glucagon, beta cells which secrete insulin, and delta cells which inhibit the secretion on glucagon and insulin: Glucagon increases the blood glucose level by stimulating the liver causing convert Glycogen into Glucose (sugar).

Is it possible that after the first meeting of male and female through sexual inter course

Ilia_Sergeevich [38]

Answer:

Yes, it is possible because, if the sperm from the male goes into the egg of the female it can cause the female to get pregnant by that male. And its very rare for the female not to get pregnant after having inter course with the male. That's only if they had unprotected sex.

I hope this helps you!

Boris Magasanik collected data on the proportion of each base in RNA from different species. To compare the relative amount of e

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.
