Explanation:
Increasing genetic variation and the environmental effects on that variation form the basis for natural selection. A species with a great deal of genetic variability is more likely to survive as a species in a changing environment than a species with limited variability.

A patient has swollen feet, ankles, and legs, and has pain in his lower back. Tests show the level of urea, a waste product, in the patient's blood has suddenly risen. Which body system is most likely not functioning properly?
A.
Nervous
B.
Excretory
C.
Digestive
D.
Reproductive
The body system that is most likely not functioning properly is excretory system. The correct option is B.
What is excretory system?The excretory system is a detached biological mechanism that removes excess, unneeded materials from an organism's body fluids to help maintain internal chemical homeostasis as well as prevent body damage.
The excretory system's function is to remove waste from the body. Water, CO2, nitrogen, salts, and heat are among the wastes. Metabolism refers to the process by which the body converts food into energy.
The primary function of the kidneys is to eliminate excess water and wastes from the bloodstream through the production of urine, a liquid waste.
As the patient has swollen feet, ankles and legs and having urea level boosted in blood, it means his excretory system has some problems.
Thus, the correct option is B.

One side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA. What would be the complementary side’s bases? How many amino acids would that sequence code for?
Answer: The arrangement of these nitrogen bases contains the code for
genetic traits. These bases are arranged in a particular
sequence, such as TGCATTCA. The sequences of DNA can vary
from several hundred bases to a million or more bases.
Explanation: put this and my teacher said amazing
The complementary side’s bases if one side of a DNA molecule has the following sequence of nitrogen bases GGTACTTACGCA are: CCTGAAATGCGT.
What is the complementary sequence?Thus, the complementary nitrogen base sequence of GGTACTTACGCA is CCTGAAATGCGT. It is because the complementary nitrogen bases pair up: A always pairs with T, and C always pairs with G.
The sequence codes for 4 amino acids. Every three nitrogen bases code for one amino acid. So, since there are 12 nitrogen bases, the sequence codes for 12/3 = 4 amino acids.
To determine the number of amino acids coded by this sequence, first note that a codon consists of three nucleotide bases, and each codon corresponds to one amino acid. The sequence has 12 bases, so there are 4 codons: GGT, ACT, TAC, and GCA. Since each codon codes for one amino acid, this sequence would code for 4 amino acids.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation
Explanation:
in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.

The seed capsules of the Himalayan balsam plant explode when touched and can eject seeds as far as 16 feet from the parent plant. Is this a structural adaptation, behavioral adaptation, or both?
Answer:
behavioral adaptation
Explanation:
A structural adaptation is defined as the adaptation in which physical features of organisms or plants while behavioral adaptation is defined as the activities an organism or plant do to survive.
The Himalayan balsam plant is an example of behavioral adaptation because it disperse its seeds when it ripe and touched by someone, for its survival it shows it dispersal behavior and spread seeds as far as 16 feet from the parent plant. In the fear of someone can harm by touching it, the survival instinct of balsam plant shows behavioral adaptation.
Hence, the correct answer is " behavioral adaptation".
why are fossil fuels supplies limited
Answer: The coal, oil and natural gas we are consuming now are the remnants of plants, trees and animals that were living hundreds of millions of years ago. There is no way to replace them, as conditions on Earth are much different now.
Explanation: Mines and wells are being depleted much faster than they were a hundred years ago when demand was much less-- fewer people, fewer cars, fewer planes. . . and people believed there was an endless supply. Many of those mines and oil wells are now empty.

B) symptom of a disease
C) environmental condition associate with a disease
Answer:
the answer is A
Explanation:
Scientific names are understood by all scientists because the names are written in
Answer:
A. binomial system
B. According to taxon
Explanation:
A. The binomial system of nomenclature brings order to a chaotic world of common names. No two kinds of animals have the same binomial name, and every animal has only one correct name, as required by the International Code of Zoological Nomenclature, thereby avoiding the confusion that common names cause.
B. Any grouping of animals that shares a particular set of characteristics forms an assemblage called a taxon. For example, a housefly (Musca domestica), although obviously unique, shares certain characteristics with other flies (the most important of these being a single pair of wings). Based on these similarities, all true flies form a logical, more inclusive taxon. Further, all true flies share certain characteristics with bees, butter-flies, and beetles. Thus, these animals form an even more inclusive taxon. They are all insects.
Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity?
Answer:
The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Explanation:
As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.
