This
is a specific response because in order to fight antigens, white blood cells,
the most important cells of the immune system, must produce large, Y-shaped
proteins known as antibodies to fight these invaders. This is a type of
specific defense (as I have identified antibodies as specific defenses is the
chart above).

Explanation:
Answer:
advantages of sexual reproduction:
it produces variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual
advantages of asexual reproduction
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
Disadvantages of asexual reproduction
it does not lead to variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Explanation:
They have 46, instead of the usual 47.
An F1 cross between true breeding brown and white lines is set up. What evidence would best support white fur being dominant to brown -----
The best evidence to show that white fur being dominant is when all the offspring after the cross are white instead of brown
They are therefore expected to produce heterozygous lines.
The evidence that would best support white fur being dominant is when all the lines produced are white despite being heterozygous.
A dominant trait is known to mask the expression of other traits.
