Nerve
Damage to nerve and blood vessels can cause lack of feeling in the extremities resulting in amputations.
Nerves are cable-like bundle of axons and specialized cells (neurons) which make up the nervous system. Nerves transmit messages as electrical signals from one area of the body to another. Nerves are classified into three groups based on the area that messages are conducted. They include; afferent nerves, efferent nerves, and mixed nerves which contain both afferent and efferent axons.
Answer:
A protein kinase is an enzyme which catalysis the phosphorylation reaction.
The phosphorylation can either activate or deactivate other proteins or receptors.
A protein kinase cascade refers to the series of events in which a chain reaction of phosphorylation takes place by which thousands of proteins are phosphorylated.
It helps in signal transduction through which signals (usually hormone) from outside the cell are amplified and transferred to the target molecule present inside the cell.
For example, tyrosine kinase cascade.
Answer:
generation 1
Explanation:
The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.
In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.
Answer:
a controlled experiment minimizes the effects other than the independent variable
Explanation:
that will increase the reliability of the results
Answer:
Herbivores: Herbivores are the organisms which feed on producers i. e. plants and takes energy from it. For example, deer, sheep and cow etc.
Carnivores: Those organisms which feed on other animals such as herbivores. They feed only on meat. For example, lion, tiger and leopard etc.
Omnivores: Those organisms which feed on both plants and animals for the uptake of energy. For example, humans and bear etc
