PLS HELP URGENT!!!!!!! The nucleus of a neuron is located in the _____. synapse cell body axon dendrite
The Nucleus of a neuron is an oval shaped membrane-bound structure found in the soma or body of the neuron. It contains the nucleolus and chromosomes, necessary for the coded production of proteins within the cell. The nucleolus of the nucleus produces ribosomes. The genetic information of an organism is coded within the long strands of deoxyribonucleic acid (DNA) from which the chromosomes are made. DNA is composed of two long chains that are interconnected in a helical arrangement. The sub units of a chromosome (genes) when activated induce the production of messenger ribonucleic acid (mRNA). mRNA is a duplicate of the information contained in the gene. mRNA leaves the nucleus and attaches to a ribosome, where is serves as a template for the production of a protein molecule
Parts of a neuron
Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.
1. Cell body
2. Axon
3. Dendrites
Myelinated neurons are typically found in the peripheral nerves (sensory and motor neurons), while non-myelinated neurons are found in the brain and spinal cord. Dendrites or nerve endings.
A population of cheetahs has a birth rate of 5 and a death rate of 15. Immigration is 2, and emigration is 4. What is its
population growth?
-14
0 -12
O 12
O 14
Answer:
-14
Explanation:
The population growth is defined as an increase in the number of individuals in a population. The growth of a population depends largely on the birth and death rates as well as migration in and out of the population. Mathematically, the population growth can be expressed as:
(B-D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In the illustration, B = 5, D = 15, I = 2, and E = 4. Therefore;
Population growth = (5 - 15) + (2 - 4) = (-10) + (-4) = -14
Hence, the population growth is -14.
Answer:

Options are not providedin the question, so the complete question is as follows:
human blood consists of groups A ,B and O. however, there is one more blood group AB which contains alleles A and B in the same genotype what is this phenomenon called?
A. coinheritance B. codominance C. incomplete dominance D. polygenic inheritance
Answer:
B. codominance
Explanation:
Codominance is a phenomenon in which an individual receives genes from each parent. If the genes or alleles are different it means, dominant allele masks the effect of the recessive allele.
Codominance occurs in the case of the AB blood type in humans in which alleles A and B are present in the same genotype.
Hence, the correct answer is B. codominance.

How would you describe the relationship between the hornworm caterpillar and
tomato plant? Do they have a symbiotic relationship? Explain your reasoning.
Answer:
See the answer below
Explanation:
The hornworm caterpillar and tomato plant do not have a symbiotic relationship. Instead, what they have what can be described as an antagonistic relationship.
In antagonistic relationships, one of the organisms benefits while the other is affected negatively. In some cases, the two organisms in antagonistic relationships are affected negatively.
The hornworm caterpillar feeds on the tissues of the tomato plant, a situation that can lead to the death of the tomato plant if it persists for long. Hence, the hornworm benefits while the tomato plant is negatively affected.

Small intestine in the site for compelet digestion for carbohydrates,protiens and fats .write down the change happen to the food in the small intestine before its obsorption ??
Explanation:
In the small intestine, enzymes are secreted on the food substances for digestion to take place before absorption in the villi in the small intestine occurs.
For carbohydrates,they are initially called maltose hence the enzyme maltase is secreted on the maltose to convert it into glucose molecules which is needed for the body.
For proteins,they are initially called peptides and polypeptides.An enzyme erepsin is secreted on the peptides and the polypeptides by the small intestine to convert them to amino acids which is also needed by the body.
For fats and oils,they are digested in the duodenum by an enzyme called lipase which coverts them to fatty acids and glycerol before it gets into the small intestine to be absorbed.

A woman with type A blood has a child with type A blood. Which of the following men could NOT be the father
Answer:
B. All males could be the father
Explanation:
A woman with type A blood either has the genotype AA or Ai. A child with type A blood will also either have AA or Ai.
Type B blood is BB or Bi. Type AB blood is AB. Type O is ii.
To find out the men not be the father, you have to do Punnett squares between the mother and father.
AA mother with BB father - type AB child
AA mother with Bi father - type AB and type A child
Ai mother with BB father - type AB and type B child
Ai mother with Bi father - type AB, type B, type A, and type O child
AA mother with AA father - type A child
AA mother with Ai father - type A child
Ai mother with AA father - type A child
Ai mother with Ai father - type A and type O child
AA mother with AB father - type AB and type A child
Ai mother with AB father - type AB, type A, and type B child
According to these crosses, all males could be the father. The father with type B blood must have the genotype Bi. The father with type A blood can have either genotype AA or Ai. The father with type AB blood will always produce a type A child except with a woman who has the genotype BB for type B blood.
