Explanation:
Lymphocytes are the second line of defence
First line of defence indiscriminately defends against all pathogens unlike secondary response which is targeted. First line of defence refers to the external body components like skin, secretions from the body in the alimentary canel
Mucus traps pathogens. Stomach acid kills pathogens
Answer:
Ss and ss
Explanation:
<em>Since the smooth trait (S) is dominant over the wrinkle trait (s), the genotype of the wrinkled pea parent is definitely </em><em>ss</em><em>.</em>
<em>Also, some of the progeny had wrinkled pea texture (ss). Each of the 2 wrinkled alleles must have been donated by each of the parent. It thus means that the smooth pea parent is heterozygous for the trait (</em><em>Ss</em><em>).</em>
Now, let us look at a cross between the two parents;
Ss x ss
Progeny: Ss, Ss, ss, ss.
Phenotypically, 50% of the progeny are smooth peas while 50% are wrinkled.
Looking at the population of each of the phenotype resulting from the cross. 252:247 is approximately a 50:50 ratio.
Hence, the genotypes of the two parents are Ss and ss.
The correct answer is:
Gravitational pull is greater on earth . As weight = mass × g so we have more weights on earth than on moon.
Explanation:
This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight. As the moon has secondary mass than the earth, it has a lighter gravitational influence and hence, we weigh less on the moon.
