Answer:
[tex]\boxed {\boxed {\sf A. \ Bring \ an \ amino \ acid \ to \ the \ ribosome}}[/tex]
Explanation:
tRNA, or transfer RNA, plays an essential role in the process of protein synthesis (creation).
After DNA is transcripted and translated, the messenger RNA is created in the nucleus and sent to the ribosome. The mRNA has codons or sets of three nucleotides. Then, the tRNA enters. The tRNA has an amino acid (the monomer of proteins) and an anticodon (three nucleotides that are complementary to the mRNA).
The codon and anticodon create base pairs, and the amino acids attach to form a protein.
Based on this information, the best answer choice is A. bring an amino acid to the ribosome

what is fhe importance of cell membranes
Answer:
Importance of cell membrane
Explanation:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

which part of the blood transports insulin to its target organs?
Answer:
endocrine glands
Explanation:
The part of the blood that transports insulin to its target organs is plasma
BLOOD:
The blood is a crucial part of the circulatory system. It functions majorly as a carrier tissue in the body. The blood carries substances like hormones, glucose, carbon dioxide, oxygen etc. from one location to the other. The blood is, however, a tissue made up of different cells and components namely: erythrocytes, leucocytes, plasma, platelets. The plasma component of the blood is its liquid part and makes up majority of blood's volume. The plasma is the medium in which most substances in the body dissolves and transported. Therefore, the part of the blood that transports insulin to its target organs is plasma.Learn more:https://brainly.com/question/18207038?referrer=searchResults

Choose the geologic formation that fits the description: rocks are stretched, moved vertically into blocks, and dropped; the lower blocks are called graben and the taller blocks called horst.
lifted fault block mountains
ocean ridges
tilted fault block mountains
folded mountains
Answer:
Horsts and Grabens - A narrow block dropped down between two normal faults is called a graben (looks like a small valley). The upraised block is called a horst (looks like a plateau). Normal faults are the dominant structures along the oceanic ridge, and in continental rifts.

Answer:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts
Explanation:
Will give brainliest to the first correct answer! Describe the factors influencing chemical bonds and the characteristics of an ionic and a covalent bond.
Answer:
FACTORS INFLUENCING CHEMICAL BONDS
Ionic bonding is a chemical bond between a positive ion and negative ion. Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
CHARACTERISTIC OF IONIC BONDS
Ionic compounds are hard and brittle. Ionic compounds dissociate into ions when dissolved in water. Solutions of ionic compounds and melted ionic compounds conduct electricity, but solid materials do not. An ionic compound can be identified by its chemical formula: metal + nonmetal or polyatomic ions.
CHARACTERISTIC OF COVALENT BOND
Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds.

During _________, energy from the Sun is stored in the bonds of sugar molecules.
Answer:
Photosynthesis.
Explanation:
"Photosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth (Global Change)."

which part of thr mitochondrion does an electron transport chain occur?
Answer:
Electron transport chain is the series of the cycle of the transfer of electrons from the one complex to other complex of the cycle. Both oxidation and redo reaction occurs in the electron transport chain.
The process of electron transport chain occurs in the inner mitochondrial membrane. All the complexes and the substrate of the cycle are embedded in the inner mitochondrial membrane. ATP is produced by this cycle located in the inner mitochondrial membrane.

Which phase determines the length of whole cell cycle? （ ） A. G1 phase B. G2 phase C. M phase D. S phase
Answer:
D
Explanation:
The S phase determines the length of the whole cell cycle.
The S phase of the cell cycle is the phase during which the cell's DNA is replicated in the nucleus while the centrosome is replicated in the cytoplasm. This phase determines the length of the whole cell cycle because the time it takes to replicate a DNA varies according to the total DNA present in the cell. The rate of DNA replication is relatively constant from cells to cells and species to species. Hence, the more the DNA, the longer the time it will take for its replication.
For example, if cell A and cell B are similar in every way except that A has higher amount of DNA than B, it will take a longer time for cell A to complete S phase than cell B. Therefore, cell A will have a longer cell cycle than cell B.
2. In sheep black wool is recessive to white wool. What happens when you mate a black ram (male) to a heterozygous ewe (female). W= white, w = black.
Answer:
50% will be white (Ww) and 50% will be black (ww)
Explanation:
Here's what the punnett square should look like.
In order for the black ram to have its coloring it would need to have 2 recessive genes (ww). The female is heterozygous, meaning she carries both genes (Ww) but only exhibits the dominant gene, in this case white fur (though they can pass the recessive gene on to their children). Simply filling out the punnett squares shows the outcome of the offspring.
What is this gas produced
