When a box is set up like this it is really a representation of MEIOSIS. The "H" and "h" on the top of the box really represent . . .
A. all of the alleles present in each parent's non-sex cells.
B. the alleles each parent can contribute in their gametes.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
This observation forms the second principle of inheritance, the principle of segregation, which states that the two alleles for each gene are physically segregated when they are packaged into gametes, and each parent randomly contributes one allele for each gene to its offspring.
Answer:
B. the alleles each parent can contribute in their gametes.
Explanation:
When a box is set up like this it is really a representation of MEIOSIS. The "H" and "h" on the top of the box really represent the alleles each parent can contribute in their gametes.

SO you hopefully selected that an Allele is a form of a gene. BUT what is this really...
A. an allele is a protein that causes hair no hair in the guinea pig
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Answer:
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Explanation:
An organism that has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig

9. because of heat given off, only 10% of the energy is going to go to each level .
Glucose is reabsorbed back into the blood by active transport define active transport
Answer:
Movement of particles from a region of low concentration to a region of high concentration against the concentration gradient that requires energy.
In a food chain and web, only 10% of the energy produced by a level in a food chain is passed on to its predator so there has to be many more “prey” than “predators”. If 2000 kcal of energy are available in grass, how much energy would be available to the cow that eats the grass? How about to the human that eats the cow?
Answer:
If only 10% of energy is passed down the cow would only get 200 kcal of energy from the grass. The human would get 10% less than that which is only 20 kcal of energy from the cow.

what is the part of endoplasmic reticulum without proteins attached?
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.

A)
Climate change will increase the loss of biodiversity at a greater rate than
pollution
Invasive species will have a greater impact in loss of biodiversity in ten
years than pollution
B)
C)
"Habitat degradation is and will continue to be the leading cause of
biodiversity loss in the Mediterranean Sea.
D)
The loss of biodiversity in the Mediterranean Sea will increase for nearly
every factor over the next ten years.
E)
Exploitation of species in the Mediterranean Sea will lead to the greatest
decline in biodiversity in the area in ten years.
Scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.
What is the significance of the loss of biodiversity in the Mediterranean?Biodiversity is low in almost every region of the world due to rapid urbanization, which has resulted in the rapid loss of plants and animals as well as a decline in their numbers due to habitat loss, and they are further impacted by climate change.
Hence, scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.

Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Belle, who was born on the same date at the same hospital. Mrs. Green, having recently seen Belle, is convinced that Belle and Georgia had been assigned to the wrong parents at the hospital. Mrs. Green thinks that Belle is her biological daughter. ABO blood analysis was performed on all individuals involved:Mr. Green: Type AMrs. Green: Type A Georgia: Type AMr. Blue: Type ABMrs. Blue: Type ABelle: Type O
Is Mrs. Green correct? Is Belle her biological daughter? Explain.
Answer:
Yes, Mrs Green is correct that Belle is her biological daughter
Explanation:
According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.
Based on the blood analysis, the following were obtained:
Mr. Green: Type A
Mrs. Green: Type A
Georgia: Type A
Mr. Blue: Type AB
Mrs. Blue: Type A
Belle: Type O
The genotype of the following blood types is as follows:
Type A - iAiA or iAi
Type B - iBiB or iBi
Type O - ii
Type AB - iAiB
From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.
However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.
