9. because of heat given off, only 10% of the energy is going to go to each level .
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.

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.

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.

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.

Observe an ecosystem in your locality, name the ecosystem, list all the biotic and abiotic components of the ecosystem, and make a diagram to represent the interaction of the components.
Answer:
Ecosystem: Native ForestBiotic components: trees, shrubs, herbs, grasses, fungi, lichens, rodents, foxes, puma, small birds, owls, birds of prey, amphibians, reptiles, snakes, insects, microorganisms. Abiotic components: Sunlight, dead organic matter, river, stones, rocks, fertile soil, nutrients.Explanation:
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living beings and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
A few examples of abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.
Examples of biotic factors are plants, animals, insects, microorganisms, etc.
An example of an ecosystem in my locality is the native forest in the hills.
The forest is composed of many vegetable species, among which we may find trees, shrubs, herbs, grasses. We can also find lichens and fungi. Many mammal species such as little rodents, foxes, puma. Many bird species, among which we can find owls and some other birds of prey. There are different kinds of snakes and reptiles. There are amphibian species near the shore of the river that is crossing the forest. The soil is quite fertile, providing nutrients to the organisms. There is too much organic matter of vegetable origin, such as leaves or fallen and dead trees. Many microorganisms live in this dead matter. Insects are everywhere. There are some steep slopes in which stones, rocks, and tree roots hold the ground.
