What is the reason offspring of the organism hydra often appear exactly the same as their parents? a) hydra may reproduce asexually. b) parent hydra undergo sexual reproduction. c) a single cell will not develop into a full organism. d) they are formed after fertilization of male and female cells.

The correct answer would be  A) Hydra may reproduce asexually.

Asexual reproduction refers to the reproduction which involves only single parent. It does not involve the formation and fusion of the gametes.

Offspring produced from asexual reproduction are often referred to as clone as they are identical to the parent cell or organism.

It includes fission (binary and multiple), budding, fragmentation, vegetative propagation et cetera.

Hydra can reproduce asexually by the process of budding. During this process, a bud or outgrowth is formed on one side of the body of the hydra. It grows while remain attached to the parental body. Once, it is matured enough, it dissociates from the parental body to become a new independent individual.

answer; a male inherits only one allele of the x-linked gene controlling hair color;

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
