The initials will still be 4 feet above the ground.
Trees do not grow from the bottom up. At the branch tips there is meristem tissue, so called the apical meristem. Trees grow in height from these apical meristems, so trees grow from the top and the initials on the bottom of the tree will stay at the same height above the ground.
Answer:
C. Prolactin
Prolactin is a
hormone that controls milk production together with oxytocin. The anterior lobe of the
pituitary gland secretes prolactin and the posterior lobe secretes oxytocin when
a baby suckles at the breast. The level of prolactin in the blood slowly
increases during pregnancy, and stimulates the growth and development of the
mammary tissue, in preparation for the production of milk after delivery.
Moreover, Prolactin
is in the highest level in about 30 minutes after the beginning of the feed,
which is most important for producing milk for the next feed.
Answer:
If there is no dominant allele for a trait present on a homologous chromosome to mask the recessive allele, the recessive phenotype will be expressed. In this case, the gene is located on the Z chromosome. In an individual with a ZW genotype (female) there is no homologous Z partner, meaning whatever allele is present on the solitary Z chromosome will be expressed.
Explanation:
Answer:
Aerobic metabolism is the most efficient way of producing ATP; it produces significantly more ATP for each molecule of glucose than anaerobic metabolism. Although the primary source of ATP in aerobic metabolism is carbohydrates, fatty acids and protein can also be used as fuel to generate ATP.
1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.
Option D
<h3><u>
Explanation:</u></h3>
Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.
He crossed them to get all tall plants in 
Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is 
of the total population of F2 generation.
