Answer: Peas have characteristics that have two forms
Explanation: He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate. Self-pollination happens before the flowers open, so progeny are produced from a single plant.
Peas having characteristics that have two forms is the reason they were
used by Gregor Mendel
Who was Gregor Mendel?He was a biologist and is regarded s the father of modern genetics. He
performed various experiments using pea plants.
The reason why the pea plants was used by him was as result of it having
characterisitics in two forms such as smooth and wrinkled etc.

That has separated the initial original population into 2 separate population which cannot interbreed
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.

Scientists have made estimates to the loss of biodiversity in the Mediterranean Sea over the next ten years due to various human-
influenced factors. The graph depicts the changes in biodiversity at present and in ten years (predicted). Which statement(s) below
are supported by the graph? Choose ALL that apply.
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.

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. 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

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.
