Explanation:
where can the fewest h+ ions be found on the pH scale, and the fewest OH- ions
The lowest [tex]H^+[/tex] concentration on the pH scale would be 14 while that of the [tex]OH^-[/tex] concentration would be 0.
pH ScaleThe pH scale ranges from 0 to 14 with 0 being the most acidic and 14 being the most basic or alkaline.
The more the [tex]H^+[/tex] concentration of a substance, the lower the pH, and the more the [tex]OH^-[/tex] concentration, the higher the pH.
Thus, at the lower extreme of the pH scale, the concentration of [tex]OH^-[/tex] is fewest, and at the higher extreme, the concentration of [tex]H^+[/tex] is fewest.

Which components bond with the nitrogenous base, guanine, in a section of double-stranded DNA?
Options:
Ribose sugar and uracil
Deoxyribose sugar, phosphate, and Thymine
Guanine, cytosine, and phosphate
Cytosine and deoxyribose sugar
Answer: Cytosine and deoxyribose sugar
Explanation: : Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. To compliment the given base,, you'd have to choose the nucleotide that would pair with it, attached to a phosphate-sugar backbone. I'm not quite sure why they didn't include phosphate in that option, but it's the only possible one. Guanine couldn't pair with any of the other listed options.

Describe how plant cells keep themselves rigid.
Answer:
Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
Explanation:
Its right
Plant cells should be treated as rigid due to the cell wall.
The information regarding the cell wall is as follows:
It is the envelope that is treated as the extracellular and present in all types of vegetables having few bacteria, fungi, etc. The composition should be changed as the organism habit. Also, the cell wall should be responsible for the plant cells rigidity.Learn more: brainly.com/question/23334479

Which of the following mutations will cause the least damage to the resulting protein? An insertion at the end of the DNA strand. deletion at the beginning of a DNA strand. A silent substitution at the beginning of the DNA strand. A missense substimion at the end of the DNA strand.
Answer:
A missense substimion at the end of the DNA strand.
Explanation:
A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes. Changes in amino acid can be very important in the function of a protein. But sometimes they make no difference at all, or very little difference. Sometimes missense mutations cause amino acids to be incorporated, which make the protein more effective in doing its job. More frequently, it causes the protein to be less effective in doing its job. But this is really the grist of evolution, when missense mutations happen, and therefore small changes, frequently small changes in proteins, happen, and it happens to be that it improves the function of a protein. That will sometimes give the organism that has it a competitive advantage over its colleagues and be maintained in the population.

Replicate the following strand of DNA:
Original DNA-- A T G A A C C A T T C A G T A T G G
Answer:
Original DNA: ATG AAC CAT TCA GTA TGG
Complimentary DNA: TAC TTG GCA AGT CAT ACC
mRNA molecule: AUG AAC CGU UCA GUA UGG
AMINO ACID: Methionine (Start) - Aspargine (Asn) - Arginine (Arg) - Serine (Ser)- Valine (Val) - Tryprophan (STOP)
2nd template:
Original DNA: ATG GGT CTA GCG AAA GAT
Complimentary DNA: TAC CCA GAT CGC TTT CTA
mRNA molecule: AUG GGU CUA GCG AAA GAU
AMINO ACID: Methionine (Start) - Glycine (Gly) - Leucine (Leu) - Alanine (Ala) - Lysine (Lys) - Apspartic Acid (Asp)
Explanation:
When you are forming the DNA complimentary strand you need to remember that they come in base pairs, and each base pairs up with a specific base. In the case of DNA the base pairs are the following:
A - T ; T - A
C - G; G - C
So:
For every A, its complimentary is T. For every T, it's complimentary is A.
For every C, it's complimentary is G. For every G, it's complimentary is C.
So in the case of your 1st DNA template:
Original DNA: ATG AAC CAT TCA GTA TGG
Complimentary DNA: TAC TTG GCA AGT CAT ACC
During transcription however, mRNA is formed. RNA does not have thymine (T), but Uracil (U) instead. So the base pairs would be different in the case of Adenine(A), thymine and Uracil.
A - U; T - A
C - G; G -C
So:
For every A, it's complimentary is U. For every T, it's complimentary is A.
For every C, it's complimentary is G. For every G, it's complimentary is C.
Going back to your 1st DNA template:
Original DNA: ATG AAC CAT TCA GTA TGG
Complimentary DNA: TAC TTG GCA AGT CAT ACC
mRNA molecule: AUG AAC CGU UCA GUA UGG
Duing translation, tRNA brings the amino acids to the mRNA strand. There is a specific RNA codon sequence that codes for a specific AMINO ACID. These codons are 3 bases grouped together. You can use the table attached to see the amino acid each combination.
Amino acids are the building blocks of protein. The DNA templates determines the type of protein that will be made. The tRNA brings the amino acid to the mRNA template. Then it drops the amino acid off, which will bond with the next amino acid coded to attach to it.
So if you take the first mRNA codon AUG, you can see in the table that it codes for Methionine, which is a start codon, meaning this is the start of a new protein. It will then attach to the next amino acid that codes for the next codon which is AAC that codes for Aspargin. They will continue until it reaches a STOP codon, which means it would be the end of that protein.
The replica of the following strand of DNA is:T A C T T G G T A A G T C A T A C C .
What is DNA ?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

Someone help? I don’t get it :(
Answer:
a) Tall and purple
b) Tall and white
c) short and white
d) short and Purple
Explanation
when both alleles are same it is called homoozygous condition and when alleles are different it is called heterozygous condition
As tall(T) and purple(P) characteristics of plant are dominant so no matter whatever the alleles are,
TT or Tt its going to be tall
PP or Pp its going to be purple
TT and PP are Homoozygous Dominant
Tt and Pp are Heterozygous Dominant
but to get short or white both the alleles should be homoozygous recessive that is,
tt for short
pp for white

I am trying to dissolve popcorn butter and milk into water. I notice the milk
dissolves, but the popcorn butter does not. Why is this? *
Answer:
Because butter is an oil-like substance. Water is a combination of hydrogen and oxygen, oil on the other hand is not. For the two to mix the oil would have to break the hydrogen chain but that is not possible because then the water won't be water.
So most fats repel water, just think about it being hydrophobic :)

Which best describes activation energy?
A. the maximum amount of energy required to end a chemical reaction
B. the amount of energy absorbed in an endothermic reaction
C. the minimum amount of energy required to start a chemical reaction
D. the amount of energy released in an exothermic reaction
Answer:
The answer is B
Explanation:
as activation energy is the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.
Activation energy is the minimum amount of energy needed to start a chemical reaction.
• The minimum amount of additional energy needed by a reacting molecule to get transformed into the product is termed activation energy.
• It can also be illustrated as the least amount of energy required to energize or stimulate the atoms or molecules so that they go through a chemical reaction or transformation.
• It is denoted by Ea and is generally measured in kilojoules per mole or joules.
• The activation energy relies upon two factors, that is, the effect of catalyst and the nature of reactants.
Thus, activation energy is the minimum amount of energy required to start a chemical reaction. Option C is correct.

It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.
Answer:
It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is the metabolic process whereby plants and other certain organisms synthesize their food (glucose) using sunlight. The general chemical equation of the photosynthetic process is depicted below:
6CO2 + 6H2O + light --> C6H12O6 + 6O2
This equation gives a general breakdown or a summary of what occurs in the process of photosynthesis, however, it is not that simple. Photosynthesis involves MANY SEPARATE STEPS that the equation is not showing. For example, the equation does not show that photosynthesis occurs in two stages namely: light-dependent phase and light independent phase.

Answer: So this is like a food chain chart. The animals at the top are one top of the food chain and do not get eaten by anything; they dont have any predators. This chart goes from bottom up. So the plants have arrows pointing to animals. Those animals that the plants are pointing to are the animals that eat that plant. And then those animals point to another animal higher on the chain and those animals that are higher eat the animals that are lower than them and have the arrow pointing at them. So the snake is pointing to the owl because the owl eats the snake. The frog is pointing to the snake because the snake eats the frog. And the list on the side of the chart is just a list of different kinds of animals. I dont remember what each of them are so you are going to have to find out what element is missing.
