The body mass index (bmi) of an adopted child will be ________ related to the bmi of the adoptive parents and ________ related t
xxTIMURxx [149]

The body mass index BMI of an adopted child will be not at all related to the BMI of the adoptive parents and strongly related to the BMI of the biological parents. The father and mother whose DNA a child inherits are commonly referred to as the child's biological parents.

Although they are not need to be blood relations, as in the case of an adopted child, legal parents have a legal family connection to the child. There are 8 different words that can be used in place of the word biological-parent on this page, including birth-father, biological-father, birth-mother, birth-parent, birth parent, father, mother, and natural parent.

Which of the following statements does not support the conclusion that giraffes are k-selected species?
Trava [24]

The correct answer is C. Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth.

Explanation:

In biology, k-selected species are species that have stable populations although they do not give birth to multiple offspring at once and individual offspring are mainly big animals that require more time to mature this makes parents invest more time and effort in them to guarantee they survive. According to this, giraffes can be classified as k-selected species because they usually have limited offspring (Giraffes rarely give birth to twins), they seem to mature slowly and offspring requires more care and time (giraffes begin mating at 6-7 years of age) and they are large when they are born (Giraffes are approximately 6’ tall and weigh 150 lbs at birth).

However, the fact "Newborn giraffes are capable of coordinated walking within an hour of birth, and running within 24 hours of birth" does not support the idea these animals are k-select species because this shows rapid maturation and little time and effort invested which is the opposite to k-selected species.

Positive impacts living in a mountain
mariarad [96]
They are a great way to beat the summer heat, with much milder temperatures at higher elevations bc there is fresh air, and studies have shown that living in higher elevations can have positive health benefits, such as improved cardiovascular health, weight loss, and longevity of life.

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, a
sattari [20]

Answer: natural selection

Explanation:Natural selection, gene flow, gene drift and mutation are the mechanisms for EVOLUTION.

The dominant purple allele must have been acquired from previous parent gene, by natural selection

Definitely the available   alleles from previous flower population were white and purple flowers. But, because the parents of purple flowers exhibit VARIATION, in their gene pool,  they showed dominance over  the recessive white colour flowers in the same population.  

◼ from Darwin’s observation and deduction, Organisms who acquired certain characteristics from variation  tend to survive than others, and therefore pass these inheritable characteristics to their offspring.

◼Thus the purple flowers dominated the population for the available resources, among the other flowers colours, (competitions) therefore it leads to a stable population in size after a period of time., while the white colour flowers are recessive

◼Darwin concluded that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).

Based on this, natural selection takes place, and the purple flowers with best variation will have selective advantage (dominance)above white colour flowers(recessive).

Consequently, they have higher survival rates compare to white flowers in the population this is   survival of the fittest by natural selection of purple flowers

The frequency of the white colour flower will reduced because of less manifestation of traits from generation to generation from reduced gene pool due to recessive trait, however the frequency of Purple flower will increase because the number of copies of allele of purple flowers is greater than the total number of all the flowers population( white flowers+purple)

Suppose a dye for staining cells stains the region where ribosomes are made. what would you expect to see inside the stained cel
ella [17]

The RNA (ribonucleic acid) and the associated proteins forms the ribosomes. These ribosomes are the site of protein synthesis in a cell. Inside the stained cell nucleus, the nucleolus part of the cell can be seen. The nucleolus is the part where the all the ribosomes of the cell are assembled.

Hence, the answer is 'nucleolus'.
