Answer:

c. the cost to growth of allocating resources to defense

d. consistent fitness benefits of high allocations to defense

Explanation:

In order to ensure survival by  escape of  grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .

The basic idea of the hypothesis is that the type   of  defence that an organism e.g plant  will adopt  against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.

What is expressed when both alleles for a gene are equally expressed as in human blood type
alexandr402 [8]

As both the genes get equally expressed in the human blood group genes, both the proteins or characters expressed by those genes get prominent in the phenotype of the organism.

<h3><u>Explanation:</u></h3>

In case of human blood type, there are co dominance between the genes coding for A blood group and B blood group. Absence of both of them produce the O blood group and presence of both of them produce the AB blood group.

The gene for A blood group codes for enzyme α-1,3-N-acetylgalactosamine transferase which attaches the N Acetylgalactosamine to surface of RBCs which are actually the A antigens.

The gene for B blood group codes for  α-1,3-galactosyl transferase which attaches galactose to surface of RBCs which are actually B antigens.

Presence of both of these genes make both N Acetylgalactosamine and galactose to be present on RBC membrane. This is why co dominance occurs in case of AB blood group persons.

Terangkan mengapa bilangan komosom berbeza pada sel anak antara mitosis dan meiosis.​(1 markah)

------------------------------------------------------------------

In mitosis, chromosomes separate only once. They line up end to end. This results in two identical, diploid cells. chromosomes failing to separate during meiosis, such as Patau syndrome, to the effects of chromosomes failing to separate during mitosis.

/

Dalam mitosis, kromosom terpisah hanya sekali. Mereka berbaris dari hujung ke hujung. Ini menghasilkan dua sel diploid yang serupa. kromosom gagal dipisahkan semasa meiosis, seperti sindrom Patau, dengan kesan kromosom gagal dipisahkan semasa mitosis.
