Answer:
Discoveries that are made through cell technology sometimes result in new regulations.
Explanation:
b. False
The study of genes and inheritance is called genetics. There are two types of alleles and these are recessive and dominant.
The correct answer is 75%.
Tall stems are dominant over short stems. Let T represent tall and t represent short. The parents are Heterozygous tall plants, which means that their genotype would be Tt and their phenotype would be tall. In a Punnett square it would look like this:
T t
T TT Tt
t Tt tt
Notice that we have 3 possible genotype combinations. When the dominant allele T is present that means that the phenotype that will be expressed is the dominant trait. In this case, we have the following genotype and phenotype:
TT Tall 1/4
Tt Tall 2/4
tt Short 1/4
The question is asking the chance the offspring phenotype is the same as the parent specifically so we can see that 3/4 are tall.
Hence, the correct is 3/4 = 75%.

The answer is phylum Sarcodina and class Heliozoa.
Actionophryx belongs to the group of Sarcodina. However, this is an older classification, and it is known that it belong to the groups of amoebas. It has a spherical body (helios, greek for sun) with axopodia (arms) so it is classified to the class sun-animalcules or Heliozoa. The body is surrounded by a glassy silica shell. It lives in freshwater, but some species are found in seas and oceans.
B) contraction of body hair muscles
C) thyroid hormones increase basal metabolic rate of cells in the body
D) blood vessels dilate and blood is directed to the superficial layers of the skin
Blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.
Homeostasis is the set of self-regulation phenomena that lead to the maintenance of constancy in the properties and composition of the internal environment.
Control in blood flow is a response that reduces heat transfer and therefore maintains body temperature.
Thermoreceptors upon detecting an increase in body temperature, are activated and transmit this information to the hypothalamus that receives the information.
Blood vessels constrict to reduce the passage of "warm" blood to the skin, allowing it to be used in vital organs.
Blood vessels in the skin dilate as a result of increased body temperature, allowing molecules to separate and occupy more space.
In addition, it increases the amount of warm blood that flows from inside the human body, increasing blood pressure and transmitting heat to the outside environment more quickly.
This allows body temperature to be lowered, a notorious consequence of this dilation of the vessels is the reddening of the skin where there is greater flow and transfer of body heat.
Therefore, we can conclude that blood vessels dilate and blood is directed to the superficial layers of the skins is one way in which the body will react to maintain homeostasis.
