Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different.
- this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.
So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.
Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.
So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.
Answer:
biology is not a physical science, as physical sciences deal with nonliving things such as atoms and whatnot. biology is a biological science
Explanation:
The correct answer is neutrons, they do not carry an electronic charge.
Hope this helps.
