Answer:
c
Explanation:
Gas exchange. Gas exchange occurs as a result of respiration, when carbon dioxide is excreted and oxygen taken up, and photosynthesis, when oxygen is excreted and carbon dioxide is taken up. The rate of gas exchange is affected by: the area available for diffusion.
It would be c. It can bond with other atoms through ionic and covenant bonds.<span />
Answer:
Dermis.
Explanation:
The skin is the outer most protective layer that differ in structure and composition of the vertebrates. The main function of skin is the regualtion, sensation and protection of the organism.
The skin is divided into different layer : epidermis, basement membrane dermis, and subcutaneous tissue. Only the dermis layer contains the living cells that are highly vascularized and present beneath the hypodermis. Dermis layer protect the body from the stress and strain.
Thus, the correct answer is option (2).
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:
Gene: The hereditary material made up of alleles.
Alleles: The alternative forms of a gene.
Dominant: An allele or trait that masks the effect of recessive allele or trait.
Recessive: An allele or trait that gets suppressed by the dominant allele or trait.
genotype: The genome of a particular organism of the genes which make up an organism.
phenotype: The physical traits or characteristics of an organism.
test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.
law of independent assortment: Alleles of different genes get assorted independently into gametes.
law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.
product rule: Independent evens can be calculated by multiplying the independent probabilities.
Addition rule: The probability which shows that one event would occur in a mutually exclusive event.
co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.
incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
