Answers
Answer:
The correct answers are options B. "It is formed at zones of volcanic activity on the ocean floor. ", C. "It is made of all types of rocks" and E. "It contains silicate minerals high in iron and magnesium."
Explanation:
In Geology, the continental crust is defined as the layer of the Earth that allowed the formation of the continents. This layer is made of all types of rocks, including igneous, metamorphic, and sedimentary rocks. This layer is also considered silica-rich, or felsic, because of its high content of silicate minerals. Regarding the thickness of continental crust, it is between 25 to 70 km thick. This is considerable thick considering that oceanic crust which barely reaches 10 km thick.

Which statements are true about variations in the genetic code?
Select all that apply.
A) All organisms display huge differences in their genetic code.
B) They may result in diseases.
C) They may provide selective advantages.
D) Slight differences in the genetic code may have significant results.
Answers
Answer:
C) They may provide selective advantages.
D) Slight differences in the genetic code may have significant results.
Explanation:
The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.
DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.
Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment. Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.

The different types of stem cells are:
Totipotent Stem CellsPluripotent Stem CellsMultipotent Stem CellsUnipotent Stem CellsWhat are Stem cells?Stem cells are defined as the raw material of the body through cells from which all other cells with specialized functions are generated. Stem cells live in the bone marrow, the spongy center of some bones, where they divide to make new blood cells.
Once blood cells have matured, they leave the bone marrow and enter the bloodstream, while a small number of immature stem cells also enter the bloodstream.
Types of stem cells:
1. Totipotent Stem Cells can differentiate into any type of cell in human body or placenta. Example: fertilized egg
2. Pluripotent Stem Cells can differentiate into any type of cell in the human body. Example: Blastocyst cells
3. Multipotent Stem Cells can develop into more than one type of cell but they are more limited than pluripotent cells. Example: Blood stem cell
4. Unipotent Stem Cells can only differentiate into a single lineage. Example: Skin stem cells

An mRNA strand is 108 nucleotides long. The maximum number
of amino acids that could form in the resultant polypeptide chain is
Answers
Answer:
36 amino acids
Explanation:
A messenger RNA (mRNA) is a type of RNA formed during transcription of DNA. mRNA contains nucleotide bases that are read in a group of three i.e. triplet called CODON. Each codon specifies a particular amino acid when translated.
Hence, in an mRNA strand that is 108 nucleotides long. This mRNA sequence will be read in three's with each three nucleotide corresponding to one amino acid. Hence, to get the maximum number of amino acids that could form in the resultant polypeptide chain, we divide as follows:
108 bases ÷ 3 bases (codon)
= 36 amino acids

Can you explain what a photon is and how it is made?
How does this impact life on Earth?
Answers
Answer:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons). The difference in mass between the reactants and products is manifested as either the release or the absorption of energy.
The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum,
photons are in light so yeah

Answers
Answer:
Muscle growth and repair would be limited
Explanation:
plz give me brainiest
Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.
What are the essential amino acids?Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.
The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.
If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.
Therefore, the absence of essential amino acids limits muscular growth and repair.

Students ere investigating of a toy car. They performed 2 trials . Trial 1 / time(s) 5 , distance(m) 10, Trial 2 / Time(s) 20 distance(m) 40. What was the average speed of the toy car during the two trials
Answers
Answer: The average speed of the toy car during the two trials is 2m/s.
Explanation:
Speed can be defined as a type of scalar quantity in physics through which the rate at which an object travels through a distance is measured in a given amount of time. The formula for determining the speed of a car is:
Speed= distance/ time which has an SI unit of m/s.
From the speed tests carried out on a toy car, the speed of trial 1 is:
Distance= 10 meters
Time= 5 seconds
Therefore trial one speed is 10/5= 2m/s
While the speed of trial 2 is:
Distance= 40meters
Time= 20 seconds
Therefore trial 2 speed is 40/ 20= 2mls
Average speed of the toy car during the two trials is: Sum of both both speeds divided by total number of trials.
Therefore: 2 m/s + 2m/s / 2= 2m/s
From the calculation, the average speed of the toy car during the two trials is 2m/s.

How did photosynthesis and cellular respiration affect Earth's atmosphere?
Answers
Answer: it is line A the other person is wrong.
Explanation:
The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
hope this helps
While cellular respiration emits carbon dioxide into the environment, photosynthesis absorbs carbon dioxide.
What is cellular respiration?Cellular respiration is a sequence of chemical processes that decompose glucose to generate Energy, which is then utilized as fuel to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
The goal of cellular respiration is straightforward: it provides cells with the energy they require to function.
The greater the rate of photosynthesis relative to respiration, the faster ecosystems 'take in' atmospheric carbon.
As CO2 levels in the atmosphere rise due to human activity, causing global warming, the balance between photosynthesis and respiration in individual plants can shift.
Thus, this way, photosynthesis and cellular respiration affect Earth's atmosphere.
