Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.

Oksana_A [137]

Answer:

The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity

Explanation:

The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.

When hypothesizing a possible phylogeny in order to classify taxa,scientists incorporate systematics to
Svet_ta [14]

Answer:

B)provide molecular or genetic information, as well as morphological information.

Explanation:

Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.

The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.

Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.

mihalych1998 [28]

Answer: Option D.

Genotype by environment interaction.

Explanation:

Genotype by environment interaction refer to a situation where two different genotypes react differently in an environment. Light skinned humans are at greater risk of skin cancer because they lack melanin which the dark people have and this melanin protect the skin from sun.

All the choices are correct. Differences in the norm of reaction I.e they react different way.

Epistasis is when the effect of a gene suppress the other.

Pleiotrophy is when a gene influence another genes phenotipically. These are all genotype enviromr interaction.
