Explanation:
Compare and contrast genetic engineering to the process of natural selection. Select all statements that are true
Available options are:
1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.
2. Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment.
3. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.
4. Like natural selection, genetic engineering may be used on all organisms, including humans.
5. The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.
Answer:
1, 2, and 3
Explanation:
Given that Genetic engineering is a scientific process of altering the genetic makeup or elements of organisms such that these organisms develop preferable traits.
On the other hand, Natural selection is a process that deals with the impartial selection of traits, that is without human input, thereby making organisms more fitted to their immediate environment.
Therefore, considering the available options, the comparison, and contrast of genetic engineering to the process of natural selection are:
1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.
2. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.
3. Like natural selection, genetic engineering may be used on all organisms, including humans.

B. The amount of the gravitational force doubles.
C. The amount of the gravitational force decreases by one-half.
D. The amount of the gravitational force remains the same.
Answer:
part b is the right answer
Explanation:
The amount of the gravitational force doubles
When the mass of an object doubles; The amount of gravitational force between it and another object whose mass stays the same doubles.
Gravitational forceAccording to Newton's law of universal gravitation;
The gravitational force between two objects is directly proportional to the product of their mass and Inversely proportional to the square of their distance apart.On this note, since the mass of the other object is kept constant; the gravitational force is doubled when the mass of the object is doubled.

Oc. through x-ray analysis
OD. through the use of magnetometers
Reset
Next
Answer:
The correct answer is - A. through the use of earthquake waves.
Explanation:
The interior of the earth can not be studied or seen by digging the hole, for that scientist normally use the movement of seismic waves, from earthquakes or nuclear test explosions, are reflected, slow down, sped up bent by passing through the different layers.
Waves behave differently as they move in different layers and their material helps scientists to learn and study the layers and their constituents. It explains that the Earth's interior has a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core.

Ernest was looking at the following diagram of a cell. Which statement best explains how he should classify the cell?
A. He should classify the cell as a plant cell because it has a cell membrane.
B. He should classify the cell as an animal cell because it has a flagellum.
C. He should classify the cell as a plant cell because it has cytoplasm.
D. He should not classify the cell as either a plant cell or an animal cell.
Answer:
C
Explanation:
I believe it is C because it looks like it has chloroplasts in it
How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.
What might occur if the stoma were all located on the top of the leaves?
Answer:
It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.
In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

Cystic fibrosis is one of the most common genetic diseases in America. It is estimated
that 1 in 23 Americans are carriers for Cystic Fibrosis. Cystic Fibrosis is a recessive trait
that follows Mendel's Law of Dominance.
Answer ALL parts of the free response below - be sure to use vocabulary and explain your
response in detail:
A. Explain what Mendel's Law of Dominance means
B. Explain how 2 parents who do NOT have Cystic Fibrosis could have a child with cystic
fibrosis.
Answer:
a.When an organism is heterogeneous for a trait, it expresses only the dominant allele
b. A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier. They are healthy and don't have the disease. But they are a carrier of the disease.
Explanation:
a.In other words, the dominant trait always masks the recessive trait.
b.A parent can be a CF carrier, and pass the CF gene on to their child.

describe how the intestines, liver, stomach, and pancreas all work together.
Answer:
They work together in the digestive system to make the food originate from the esophagus to the anus.
Explanation:
Answer:
Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
Some extra info:
Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.
Pancreas. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts.
Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.
Small intestine. Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Large intestine. In your large intestine, more water moves from your GI tract into your bloodstream. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.
