Answer:

During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.

In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance

igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

__________ death rates and __________ infant mortality rates are due in large part to technological advances, improved sanitatio

Elis [28]

<h2>Both are Lower</h2>

Explanation:

Death rate is also known as Mortality rate.

Death rate is the ratio of total deaths to total population in a specific area or community over a specific time period.
Death rate = number of deaths/1000 of the population/year.
The death of young children under the age of 1 is known as Infant mortality rate.

The infant mortality rate (IMR) meausres the death toll which is the number of deaths of children under one year of age /1000 live births.

You have a cup of vegetable oil and a vial full of normal phospholipids. What would you predict would happen if you dropped the

Jobisdone [24]

The vegetable oil is made up of chains of long fatty acids. These long chains of fatty acids are non-polar in nature, i.e, they do not interact through ionic forces rather by covalent forces. The phospholipids are also long chain fatty acids with an ionic head. The mixing of the vial of phospholipid in vegatable oil will lead to the formation of a micelle where the lipophilic ends of the phospholipid will be on the outside and the lipophobic end will be towards the centre of the micelle.
