ome people have dimples; other people do not. Having dimples is dominant over not having dimples.
If the allele for having dimples is represented with the letter D, what allele combinations can result in having dimples?
Answers
Why? Dimples are dominant meaning that if one dimple trait is in allele it will be shown even if there is a recessive trait. So DD and Dd are the answers

describe the role of insulin in regulating blood sugar levels
Answers
Answer:
Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
A space used in industry or research settings that has a controlled level of contaminants is called a __________.
Answers
Answer:
Clean room.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).
Hence, a space used in industry or research settings that has a controlled level of contaminants is called a clean room.
A clean room refers to environment or laboratory that is typically free from dust, pollution or any form of contaminants, used for carrying out experiments and manufacturing processes.

25% red, 50% pink, and 25% white
Explanation:
construct a punnett square with the genotype RW and cross them to get genotypes of RR, RW, RW, and WW.
RR is red and occurs once so that is a 25% chance (1/4)
RW is pink and it occurs twice so that is 50% (2/4)
WW is white which occurs once and it is another 25% (1/4)
A red flowered Snapdragon(RR) is crossed to white flowered Snapdragon(rr). The F1 individuals are Pink flowered(Rr). When F1 individuals are self crossed, in the F2 generation, 1 plant with red flowers(RR-25%), 2 plants with pink flowers(Rr-50%), 1 plant is with white flowers(rr-25%) are formed. The phenotypic ratio is 1:2:1 and genotypic ration is 1:2:1.
So, the correct option is ‘25%’.
if you cross Bb with bb what's is the genotype ratio?
Answers
Answer:
Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.
Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.
Explanation:
Answer:
I don't know about the ration but it's going to be 25% chance for them to have an offspring with blue eyes as there is a presence of a dominant allele

Answers
Answer:
b hypothalamus
Explanation:
The hypothalamus controls hunger and satiety. Therefore, option (B) is correct.
What is the role of hypothalamus?
The hypothalamus regulates circadian rhythms, appetite, thirst, and body temperature. The study of illnesses and diseases associated to the neuroendocrine system may benefit from using rat hypothalamic neurons.
The arcuate nucleus, or infundibular nucleus in humans, is a region of the hypothalamus that permits peripheral peptides and proteins to cross the blood-brain barrier and interact with its neurons.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d). If a squash plant pure-breeding for white, disk shaped fruit is crossed with a plant pure breedig for yellow, sphere shaped fruit, CACULATE GENOTYPIC AND PHENOTYPIC RATIOS
Answers
Answer:
Genotypic ratio = 16 WwDd: 0
Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit
Explanation:
This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).
According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:
WWDD - WD, WD, WD, WD
wwdd - wd, wd, wd, wd
Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.
The genotypic ratio is 4 WwDd: 0
The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.

Which DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells?
Answers
The DNA-containing central cell structure found in plant and animal cells is absent in bacterial cells is nucleus.
What is nucleus?The part of a cell that houses the chromosomes in biology. The membrane-enclosed nucleus is where RNA is synthesised from the chromosomal DNA.
DNA is organised into chromosomes in the nucleus, which is located in the centre of the cell.
The double nuclear membrane (outer and inner) that separates the nucleus from the cytoplasm, known as the nuclear envelope, envelops it. The rough endoplasmic reticulum and the outer membrane are one unit.
The nucleolus' main job is to facilitate ribosome biogenesis by assembling and digesting rRNA into preribosomal particles.
Bacterial cells lack the nucleus, the primary cell structure that houses DNA, that is present in plant and animal cells.
Thus, nucleus is only present is eukaryotic cells.
