Answer:
because a change in the DNA sequence
Explanation:
Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.
what are the differences in competitors between wet/dry seasons in Zimbabwe?
Answer:
There are only 2 seasons: wet season (summer) and dry season (winter). Usually the dry season is longer. During the dry seasons plant life and animal life suffers, but as the rainy season begins life flourishes in this area.
Explanation:
In dry seasons the living organism like plant life and animal life suffers where as in wet or rainy season life flourishes
What are the differences between dry and wet season ?The dry season in Zimbabwe occur from April to October but in rainy season rain fall occur from November to March. In April or May, long grasses and the animals are observed.
In general the dry season best seen from August to the end of the dry season in October. The landscape can be observed as harsh and very dry during this time.
In November the rainy season has been started, certain animals will be dispersed during the start of rainy season and the most challenging time visit Zimbabwe is from December to March.

"An advantage of ______ reproduction is that a genetic disorder in a parent might not affect The offspring
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
got 100
Answer:
An advantage of sexual reproduction is that a genetic disorder in a parent might not affect the offspring.
Explanation:
Since there are only two types of reproduction, sexual and asexual, andin asexual reproduction, the offspring gets all the qualities of the parent, we can determine that the offspring might not get the genetic disorder from the parent IF it is sexual. That is because there are 2 parents, hence giving a 50-50 chance to get it.

What does it mean if an organism is multicellular?
The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?
Answer:
True
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

To maintain turgor pressure (the main pressure of the cell contents against the cell wall), cells in both the leaves and stems of most non-woody or herbaceous plants contain
Answer:
They contain a vacuole
(I think what the question is asking for)
Explanation:
The vacuole is what takes up most of the plant cell's mass. It stores water so when you have high turgor pressure, the vacuole presses against the cell wall while when the turgor pressure is low, the vacuole is shrunken.

The pancreas is a human body organ that produces digestive enzymes and two very important hormones : insulin and glucagon. These two hormones work together to regulate the level of the sugar glucose in the bloodstream. If glucose levels in the bloodstream are too low, the pancreas secrets glucagon which causes the glucose level to increase. if blood levels are too high, the hormone insulin will lower the glucose level. if a person has just eaten a meal containing a large amount of sugar and other carbohydrate, which statement best describes how the pancreas will respond.
Answer:
If you have just eaten large amounts of sugar, your pancreas will in return release a large amount of insulin to even it out again.
Explanation:
A student performs a diffusion lab using a starch/glucose solution, iodine solution, and dialysis tubing (cell membrane). The student waits 10 minutes before making observations. The student reports that iodine moved across the cell membrane. What observation helped the student draw their conclusion?
Answer:
Diffusion takes place in this process where iodine and glucose molecule diffuses through the dialysis tubing whereas the starch did not. Diffusion takes place on the basis of the size of the molecules.
Starch molecules are large in size whereas iodine and glucose are much smaller therefore they are able to diffuse. If both iodine and starch would have diffuses through the tubing the color would change into dark purple by mixing thee both molecules.

Number of chromosomes?
Sex of individual?
Normal? Yes or no.
If abnormal, what chromosome pair?
This is the picture of karyotype. Karyotype is a collection of a Individuals chromosome. Like pairs are separately represented from the unlike pairs, It is generally used to study the chromosomes and the abnormalities found in the number of chromosomes.
_____________________________________CHROMOSOMAL NUMBER 18:Every chromosomal pair seems fine, except the chromosomal pair number 18. Because as you ca see that it has 3 chromosomes instead of 2. This impairment in the chromosomal pair is called trisomy as it has 3 chromosomes.
_____________________________________TRISOMY 18:Trisomy 18 is also called Edwards syndrome. It is a chromosomal condition associated with abnormalities in more than one part of the body. Individuals with trisomy 18 often mature slowly than normal fetus before birth and they have lower weight at the time of birth as compared to the other children.
_____________________________________Best Regards!'Borz'There are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
What is the chromosomal abnormality?The chromosomal abnormality is caused by the mutation in the chromosome number and includes either the deletion of the chromosome or the addition of the chromosome in a homologous pair. The chromosomal abnormality has many negative consequences as well, some extra copies in the sex chromosome pair cause infertility, etc., while deletion causes life-threatening conditions.
Hence, there are 23 pairs of chromosomes in total, and the individual is male because it has one X and two Y chromosomes, but this individual is abnormal because of the trisomy in the 18th chromosome, as the 18th pair has three chromosomes.
