The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
B) It requires energy
D) It involves the help of carrier proteins.
Answer:
a, b, d y e
Explanation:
We can define thermogenesis as the method of production of lime or temperature that a living body generates, in biology it is studied that this does not occur in all animals, but is seen in so-called warm blood and some plants, there are three types of processes identified in animals:
NEAT: defined as thermogenesis that occurs without the presence of physical activity
DIT: defined as the thermogenesis that occurs with physical activity
EAT: defined as the thermogenesis that occurs with the consumption of food or diet
Thermogenesis under the thermogenin protein found in brown adipose tissue produces a disengagement of protons within the mitochondria, prevents ATP synthesis and is capable of inducing temperature with the flow of protons, it also intervenes by increasing glycolysis, lipogenesis and gluconeogenesis with which its final result in these processes is the production of energy. The effect of the sympathetic nervous system and thyroid hormones that can balance heat production without generating abnormal movements such as tremor is also recognized.
Thus we deduce that:
electron transport allows heat flow without causing tremors
Thermogenin is involved in allowing protons to enter the mitochondria and the ATP production process is carried out.
hydrolysis of fatty acids occurs in the presence of norepinephrine
in brown adipocytes ATP synthase can be avoided
Answer:
IgE
Explanation:
Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.
They are known to be produced by produced by plasma cells (white blood cells).
Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.
In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
Answer:
nucleosomes = 1.65 x 10^6
H2a = 3.3 x 10^6 molecules
H2b = 3.3 x 10^6 molecules
H3 = 3.3 x 10^6 molecules
H4 = 3.3 x 10^6 molecules
Explanation:
It was mentioned in the book Principles of Genetics By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
