A. DNA molecule
B. amino acid
C. RNA molecule
D. protein
Answers
Answer:
A
Explanation:
as is double helix and it also contain thymine which is only in DNA and RNA has uracil.
hope this make sense:)
Macromolecules like proteins and nucleic acid are large structures that are essential for biochemical processes. The figure shows the structure of DNA.
What is DNA?DNA is deoxyribonucleic acid that is a nucleic acid and is an important genetic material found in living organisms. It is composed of a double helix structure.
The nucleotide structure of the DNA constitutes deoxy sugar, phosphate groups, and nitrogenous bases like adenine, thymine, guanine, and cytosine.
It cannot be RNA as in RNA, uracil is present at the place of thymine. It cannot be an amino acid or protein as well because they are not composed of the amine, carboxylic, and the R group.
Therefore, the given figure is option A. DNA molecule.

the process that plants go through to capture and use energy from the sun to make food (glucose ) is called Photosynthesis
The process that plants go through to capture and use energy from the sun to make food ( glucose ) is called [tex]\sf\purple{photosynthesis}[/tex].
..................................................More:-❀ Photosynthesis is a process by which phototrophs convert light energy into chemical energy.
❀ The word “photosynthesis” is derîved from the Greek words "phos" (which means “light”) and "σύνθ-εóîς" (which means “combining together.”) And so it means “combining together with the help of light.”
❀ The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.
❀ Following is the photosynthesis formula:

Si contamos con mas tecnologia ahora,por que creen que no es posible regresar de Marte si lo es regresar de la Luna
Answers
Answer:
Debido a la gravedad.
Explicación:
No es posible regresar de Marte si es posible regresar de la Luna porque la masa es un planeta que tiene una alta fuerza de atracción gravitacional en comparación con la luna que tiene una fuerza gravitacional muy baja. La luna es una estrella que tiene una fuerza gravitacional baja mientras que, por otro lado, Marte es un planeta y más grande que la luna, por lo que tiene más fuerza de atracción gravitacional en comparación con la luna y esa es la razón por la que no podemos regresar de la luna fácilmente desde el Marte en comparación con la luna.

Mold is made up of many fungi cells. Mold would be considered what type of organism?
A. unicellular
B. prokaryotic
C. multicellular
Answers
Answer:
The answer is Multicellular
Mold would be considered a multicellular organism, which is made up of many fungi cells.
When it is said that living beings are made up of cells, what is meant is, if they are multicellular organisms.
Eukaryotes include all members of the animal and plant kingdoms, including fungi, which exist both in multicellular forms (molds) and in unicellular forms (yeasts), and protozoa, which are exclusively single-celled.
About multicellular organism molds:
The filaments that make up the mycelium are called hyphae. The hyphae may be separated into generally multinucleated sections by means of perforated septa, or may be absent.The cell wall of the mycelium of molds resembles an extensive tubular system through which the cytoplasm advances to disperse and search for nutrients.Therefore, we can conclude that mold would be considered a multicellular organism, which is made up of many fungi cells.

Use the following information to answer the questions below. Skin color in a certain species of fish is inherited via a single gene with four different alleles. One fish of this type has alleles 1 and 3 (S1S3) and its mate has alleles 2 and 4 (S2S4). If each allele confers a unit of color darkness such that S1 has one unit, S2 has two units, and so on, then what proportion of their offspring would be expected to have five units of color
Answers
Answer:
1/2 = 50% of the progeny is expected to have 5 units of color → S1S4 + S2S3
Explanation:
Available data:
Single gene with four different alleles → S1, S2, S3, S4Each allele confers a unit of color darknessS1 one unitS2 two unitsS3 three unitsS4 four unitsCross:
Parentals) S1S3 x S2S4
Gametes) S1 S3 S2 S4
F1) 1/4 = 25% of the progeny is expected to be S1S2 → 3 units
1/4 = 25% of the progeny is expected to be S1S4 → 5 units
1/4 = 25% of the progeny is expected to be S2S3 → 5 units
1/4 = 25% of the progeny is expected to be S3S4 → 7 units
1/2 = 50% of the progeny is expected to have 5 units of color → 1/4 = 25% S1S4 + 1/4 = 25% S2S3

During a baseball game, a hitter strikes the ball with a bat. When this happens, the ball and the bat exert a
force on each other. Why does the ball accelerate away from the bat more than the bat accelerates away from
the ball?
Answers
Answer:
The ball has greater velocity before the collision, so the force affects the ball more than it affects the bat. The ball has less mass, so the equal force on the ball and the bat causes greater acceleration of the ball. The bat exerts more force than the ball because the batter is exerting a force on the bat as it hits the ball
