The enzyme choline acetyltransferase catalyzes the reaction between acetyl-CoA and choline resulting in the formation of the neurotransmitter acetylcholine. This enzyme is produced within the cell body of neurons, but the synthesis of acetylcholine occurs within the axon terminals. What best describes the axonal transport mechanism associated with this process?
Answer: Anterograde direction.
Explanation:
Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.
The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.
This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.

QUESTION 5
Diffusion involves the movement of particles from a region of
А,
low concentration to a region of high concentration through a partially permeable
membrane
B
c.
high concentration to a region of low concentration through a partially permeable
membrane
low concentration to a region of high concentration with or without passing through
partially permeable membrane
high concentration to a region of low concentration with or without passing through
partially permeable membrane
Answer:
High concentration to low concentration with or without a partially permeable membrane
Explanation:
Diffusion is the movement of particles from a region of high concentration (where there is alot of the particle) to a region of low concentration (where there is less of the particle) until it is evenly distributed.
The definition didn't state whether or not a partially permeable membrane was required.
It doesn't have to pass through a membrane. for e.g. spraying perfume at one side of the room and it is smelt on the other side. Meaning it diffused through the room. There was no membrane present.
It can also pass through a membrane for e.g diffusion of oxygen gas into cells (cells have membranes therefore the oxygen diffused through the membrane.)
canicas y piedras son homogéneas o heterogéneas

Answer:
Heterogéneas.
Explanation:
Se denomina "heterogénea" a toda aquella cosa que, por sus características particulares, no puede ser asimilada a otras sino que posee una individualidad particular que impide dicha asimilación. Así, por ejemplo, una piedra y una canica son heterogéneas entre sí, en tanto no poseen las mismas características y por lo tanto son claramente diferenciables.

Q. respire
Answer:
In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).
Answer:
E
Explanation:
Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.

In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems?
Answer:
I feel like in most cases, every organ in the organ system has only one specific function. But some organs may be a part of one or more organ systems. For example, the liver is a part of the digestive system but also plays an important role in the excretion system.

map.
A. ordnance survey
OB. geologic
OC. environmental
OD. biogeographic
Reset Selection
Answer:
Biogeographic
Explanation:
The analysis of the geographic distribution of species, creatures, and other living things is known as biogeography. It's not only about habitation variations; it's also about the variables that cause differences in distribution.
Distribution of white tailed deer is an example of biogeography or Biogeographic research.
a) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first two nucleotides of the codon?
b) In how many cases would you fail to know the first two nucleotides of the codon if you knew which amino acid is specified by it?
Answer:
a) 28 cases
b) 3 cases
Explanation:
a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc.
b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these 3 cases would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.
See the attached image for the genetic code.
B is dominant for black fur over b for white fur. Cross two rabbits, heterozygous for fur color.
Answer:
Parental cross: Bb x Bb
F1:
- Expected phenotypic ratio: 3/4 black fur (B_); 1/4 white fur (bb) >> 3:1
- Expected genotypic ratio: 1/4 BB; 1/2 Bb; 1/4 bb >> 1:2:1
Explanation:
A gene variant or 'allele' is dominant when it completely masks the presence of the other allele called recessive in individuals that are heterozygous for that gene. In this case, the allele 'B' associated with the black fur phenotype exhibits complete dominance on the allele 'b' associated with the white fur phenotype. In consequence, the mating between two heterozygous (Bb) parents will produce an F1 generation with an expected phenotypic ratio for the fur trait of 3:1, i.e., 3 black fur individuals (B_ genotype) and 1 white fur individual (bb genotype), and an expected genotypic ratio of 1:2:1 among BB, Bb and bb genotypes.
Do you think landowners should be compensated for their loss by the federal government for habitat conservation of endangered species?
Answer:
Yes
Explanation:
Unless they have a permit to inhabit endangered species. They shouldn't be caring for a endangered species, because they could be doing something to hurt it even if they don't mean to. By law they do confiscate them unless you have a permit.

AL COMPRAR UN PRODUCTO NOS REBAJAN UN 8% PAGUE 48.000 EUROS . ¿CUÁL ERA EL PRECIO ORIGINAL?
Answer:
V.O = 52.174.
Explanation:
¡Hola!
En este caso, considerando la información dada, es posible para nosotros inferir que al haber una rebaja del 8%, pagamos solamente el 92% del valor original del producto, esto quiere decir que debemos dividir el valor pagado, €48.000, por 0.92 con el fin de conocer dicho precio original:
[tex]V.O=\frac{48.000}{0.92}\\\\V.O=52.174[/tex]
