Answer:

25% or 1/4

Explanation:

The gene for colour in Heliodors is controlled by two contrasting alleles that codes for Red (R) and Yellow (Y) colours. However, these two alleles exhibit incomplete dominance, which is a phenomenon whereby a combination of both alleles gives rise to a third intermediate phenotype that is a blending of the other two parental phenotypes. In this case, both colours gives rise to a heterozygous Orange coloration (RY) in Heliodors.

However, if two orange Heliodors (RY) are crossed, four possible offsprings will be produced with the genotypes: RR, RY, RY, YY. This shows a phenotypic ratio of 1 red: 2orange: 1yellow. Hence, the probability of having a child with red coloration is 1 out of 4 possible offsprings i.e. 1/4.

Expressing this in percentage, we have 1/4 × 100 = 25%.

Growth Hormone and insulin are protein hormones that promotes the growth and regulation of substrate metabolism.

Explanation:

The Growth Hormone performs the metabolic actions in various tissues like liver, muscle, and pancreas through insulin growth factor. Insulin slows down the growth hormone signalling through the growth hormone receptor. It is important for maintaining the responsiveness of liver to growth hormone.

The insulin signalling pathway is very important in metabolic diseases like diabetes and aging. These insulin activates a phosphorylation cascade that branches to form a network affecting multiple biological processes.

Answer:

Option:Symbiosis in which both organisms benefit ecological niche.

Explanation:

Symbiotic association between any living organism:

The symbiotic association is the connection between any organisms, which are either benefited by each other or the relationship can be very negative for the either one, or it may be neutral in nature for both the organisms living inside a symbiotic relationship.

The symbiotic association between the different organisms are of four different natures or levels,which are as follows:

Mutualism: Inside the relationship or connection between any number of organisms in which there is mutual benefit for both the organisms, is called as the mutualism. For example, the insecticides living in the plants roots or any part of its body.
Parasitism:Such a symbiotic relationship is which between any two living organism either one of them is benefited while the other one is harmed by its effect. For example, the tape worms in the living body.
Predation: It is more simple to understand as the prey is hunted down and killed in order to fulfill the needs of the predator.For example the lion and the impala.
Commensalism: The type of association between the living organism in which one of the organism is benefited, while other is neither benefited nor harmed. For example the marine life on the back of the crab's body.

What is the percent by mass of 8.0g copper is added yo enough zinc to produce 100g an alloy brainly

kogti [31]

Answer:

Explanation:

Given that,

Mass of solute = 8 g

Mass of soultion, (mass of alloy) = 100 g

We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :

$\text{Mass}\%=\dfrac{\text{Mass of solute}}{\text{Mass of solution}}\times 100\\\\=\dfrac{8}{100}\times 100\\\\=8\%$

So, the percent by mass is 8%.
