If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answer:
A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.
The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.
Hence, the wide base shows higher population of younger age children and higher birth rate.

What is dehydration?A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.
These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.
Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.

HIV is a retrovirus. Which sequence does it use as part of its reproductive
cycle?
A. RNA DNA → RNA protein
B. protein
- DNA - RNA → DNA
C. DNA - RNA DNA protein
D. RNA - protein - RNA - DNA
HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle. So, the correct option is A.
What is HIV?HIV stands for Human Immunodeficiency Virus which is defined as a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS which stands for acquired immunodeficiency syndrome. There is currently no effective cure, while once people have HIV, it remains with it for life.
HIV can spread through sexual contact, illicit injection drug use or sharing needles, contact with infected blood, or from mother to child during pregnancy, childbirth or breastfeeding. HIV is a retrovirus whose sequence is RNA DNA → RNA protein which it uses as part of its reproductive cycle.
So, the correct option is A.

Animals that are best adapted to their environment are more likely to survive and reproduce. This principle is called _______
Answer: natural selection
Explanation:
What role does reproduction play in both natural and artificial
selection?
Answer:
It allow organisms to pass down their traits to the next generation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Hence, the role which reproduction play in both natural and artificial selection is that it allow organisms to pass down their traits to the next generation.

DNA _____.
is a long, single chain of nucleotides
cannot determine behavior traits
contains coded information for the creation of proteins
is enclosed by a nuclear membrane in prokaryotes
Answer:
Answer:
The correct answer would be "contains coded information for the creation of proteins".
DNA or deoxyribonucleic acid is a polymer of nucleotides.
It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.
In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.
The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.
It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

Transpiration is the evaporation of water from the surface of a plant. Explain.
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.

What letters represent the four nitrogen bases in DNA?
Answer:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
Explanation:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
What is base-pairing rule?According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
The bases are Adenine, guanine, guanine, cytosine, thymine, adenine the string of their base pair would be Thymine, cytosine, cytosine, guanine, adenine, thymine.
DNA stands for Deoxyribonucleic acid. It is made up of two complementary strands. There are four nitrogenous base present in the DNA strand. These are-
Adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair with bases on the complemenatry strand just according to the Watson and Crick base pairing ( A=T, G ≡ C ). Uracil is another nitrogenous base. But it is present in RNA in place of Thymine.
Thus, bases found in the DNA are Adenine, thymine, guanine, cytosine.
