The provided question lack the essential part which is required to answer the question, however the correct part is attached with with the question as image.
Answer:
From the provided punnett square it is clear that the genotype of parents are Rr for each. On this basis offspring which is maria that can be either RR, Rr, or rr. Maria have chances to get RR= 25%.
There can be no 100 surety of the phenotype of maria as there is 25% chances of rr and 75% of ability of tongue rolling.
to get Rr=50% and rr = 25%
Answer:
25%
Explanation:
From the description;
The parents: half shaded circle and square = heterozygous parents
The offspring:
unshaded square = homozygous normal
half shaded circle = heterozygous normal
half shaded circle = heterozygous normal
completely shaded square = affected (homozygous abnormal)
The unshaded and half shaded offspring are normal and do not have sickle cell anemia. The completely shaded square represents a male offspring with sickle cell anemia.
<em>Out of 4 offspring, 1 is affected for sickle cell anemia. Hence the percentage of the offspring that have sickle cell anemia is 25%.</em>
Hi , well the average weight of terrestrial mammals+birds+reptiles+dinosaurs is 1,269p , marine mammals + terrestrial mammals 1,037p, only terrestrial mammals 106 pounds.
The gastric pits are at the bottom of the infoldings of stomach’s lining epithelium. The gastric gland is located at the bottom of the gastric pits. There are different types of cells in the glad that secreted digestive enzymes.
For example: At the base of the gland, chief cells secrete pepsinogen that digests proteins and lipase that digest fats.
Oxyntic cells are along the length of the gland and that secrete hydrochloric acid (HCl), that is required to activate other enzymes.
Mucous neck cells secrete mucous.
Answer:
Because lytic virus reproduces its phages immediately leading to bursting of the host cell for the new phages to leave.
Explanation:
Viruses employ two major cycles to reproduce themselves namely: lytic and lysogenic cycles. Lytic cycle involves the entrance of the viral cell into its host, using its host's replicational abilities to reproduce and bursting of the cell.
The lytic cycle is carried out by strains of virus called VIRULENT STRAINS. They use the host cell to produce many virions and destroy the cell by lysis in order to leave the host cell. This accounts for the reason they DO NOT STAY LONG IN THEIR HOST CELL.
