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) .
A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. While conducting her observations, the scientist noticed that the cells were undergoing cell division. What difference would the scientist expect to observe between the body cells and the sex cells of the organism as they underwent cell division?
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Body cells divide by mitosis for sexual reproduction, while sex cells divide by meiosis for the growth and repair of cells.
Body cells divide by meiosis for the growth and repair of cells, while sex cells divide by mitosis for sexual reproduction.
Body cells divide by meiosis for sexual reproduction, while sex cells divide by mitosis for the growth and repair of cells.
Answer:
The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Explanation:
The behavior of the different cell types with respect to their division depends on the functions that each type has.
Somatic cells are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.Sex cells or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.The characteristics described for each cell type explain why the other options are not correct.
Answer:
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Answer:
C-U-A-G-G-A
Explanation:
took the quiz this question right with this answer
The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
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.

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.

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.

A. Molecular collisions of visible light and infrared radiation
B. Electromagnetic radiation in the form of radio waves
C. Electromagnetic radiation in the form of matter
D. Molecular collisions of gas atoms
The statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
What do you mean by Radio waves?Radio waves may be defined as electromagnetic waves enclosing a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz. These waves are used in radio, television, and satellite communications.
The Sun's energy consists of UV radiations but these radiations are not consumed by radio waves, resulting in the consumption of electromagnetic radiation on the Earth's surface.
Therefore, the statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.

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
