Answer:
b they all serve a differnt function
Explanation:
Different types of cells are present within an organisms serve different function.
What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.Hence the correct option is B.

Explanation:
Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Answer:
Binding of ACh (acetylcholine) to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is ACh (acetylcholine) .
Which compound forms when carbon dioxide diffuses and reacts with seawater?
A. Hydroxide ions
B. Carbonate

Answer:
It's D
Explanation:
When CO2 reacts with water first carbonic acid is produced. then this carbonic acid will transform to H+ and HCO3-.

DNA provides a very significant role in the formation and development of an organism.what is that role?
Answer:
The significant role that DNA provides is the organism's genetic information. It stores its information inside, and that's what makes up all the traits of the organism. All known cellular life contains DNA for this reason, and basically serves as long-term storage of information about the organism.

Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?
Answer:
The Golgi apparatus plays a central role in molecular transport after biosynthesis.
Explanation:
Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.
The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.
Imagine that a biological anthropologist 10,000 years in the future is examining our fossil remains. The anthropologist notices that humans have broad incisors and molars with rounded cusps. How do you think the anthropologist would interpret these traits---what diet would these traits indicate
Answer:
They were frugivores
Explanation:
Frugivores are animals that mainly eat raw fruits, vegetables, roots, seeds, shoots, etc. Frugivores need to eat diverse fruits and succulent fruit-like vegetables to fulfill their nutritional requirements, although they can supplement this diet with flowers, nectar, small insects, etc. Among their adaptations for fruit consumption, frugivore teeth are clearly distinct, having broad incisors to peel tough fruit rinds. Moreover, these animals generally have long small intestines to digest the fruit.

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection
Answer:
C. group
Explanation:
Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.
What is group selection?A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.
Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.
The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.
Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.
The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing
Thus, the correct option is C.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
