Explain the differences between DNA and RNA.
Answer:
Explanation:
The difference between DNA and RNA is.....
DNA = Double-stranded
RNA = Singer-stranded
DNA = The sugar moiety is deoxy ribose
RNA = Ribose is the main sugar
DNA = Thymine is always there, but uracil is never found
RNA = Pyrimidine components differ. Thymine is never found
DNA = It follows Chargaffs rule (since it's double stranded)
RNA = Doesn't follow Chargaffs rule (since it's single stranded)

Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.
Coal:
Petroleum:
Natural gas:
In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
Coal:
Coal is primarily used as fuel to generate electric power
Petroleum:
heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials
Natural gas:
heating, cooking, and electricity generation.
it all end up in the atmosphere
Explanation:
The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.
Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.
This is about description of fossil fuels which are simply fuels that are formed from natural processes.
The uses and end products of fossil fuels are talked about in the explanations below;
1) (I) The primary use of the fossil fuel named coal is to generate electricity.ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.
2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.
3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.

The chemical reaction that represents photosynthesis is 6 H20 + 6 CO2 → C6H12O6 +6
O2. What are the reactants?
Answer:
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2. 6CO2+6H2O→C6H12O6+6O2. In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts. Chloroplasts contain disc-shaped structures called thylakoids, which contain the pigment chlorophyll.

Two genes (R or r) and (D or d), each with a dominant and recessive allele, are
inherited independently of each other. Which of the following combinations
could result in gametes of a plant with an Rr Dd genotype?
A. RD and rd
B. DR, Dr, Rd, dr
C. DD, Dd, dd, RR, Rr, rr
D. Rrand Dd
Answer:
B. DR, Dr, Rd, dr
Explanation:
This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.
Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:
DR, Dr, dR, dr

Answer:
D
Explanation:
the nuclei of the skin cells of the frog contain all DNA needed to clone the frog
The branch of science which deals with the study of a living being is called biology.
The correct option is D
The branch of biology which deals with living things along with technology is called biotechnology. In the question, the genes from the Skin cell of the frog are injected into the egg cell.
This experiment is done because scientist wants to inject the skin cell and pass this character to the new frog without fertilization.
Hence the correct option is D that is The nuclei of the skin cells of the frog contain all the DNA needed to clone the frog.

, where should the capillaries and lymphatic vessels be placed tomaximize the absorption of nutrients from food
Answer:
They should be placed in the small and large intestine.
Explanation:
The small and large intestine is the part of our digestive system that absorbs the nutrients from food. Previous to this step, the food went through the mouth, the esophagus, and the stomach. In those places, it was processed so that the intestines could absorb the nutrients from the food easily/
For nutrients to be absorbed, they should be in stretch contact with the intestines' walls where the smallest arteries, which are called capillaries, are present and will take the nutrients into its interior where the blood is. Also, the intestines have lymphatic vessels. These ones will protect our body from any antigen since they are part of our immune system.

In chemical reactions atoms are
Neutralized
Destroyed
Created
Rearranged
Answer: Rearranged
Explanation:
In chemical reactions, atoms cannot be destroyed, created, or neutralized, and that is why the only correct answer, in this case, is that atoms in chemical reactions can be rearranged.
They aren't destroyed and they can never be destroyed and also they cannot be created because of the law of conservation of energy in chemical reactions.
This law is considering that ''A matter cannot be created nor destroyed, it can only be formed in one way or the other.''
