<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
Answer:
Your answer should be Parasitism.
Example:
A flea on a dog: The flea benefits by getting shelter, and the food it needs to survive, the dog is harmed by getting its blood taken and getting infections.

Oceans regulating climate on land.
Explanation:
1. The given blank can be filled with vestibular nerve.
The vestibular nerve in humans conducts sensory information conducted by the vestibular hair cells situated in the utricle and the saccule, that is, the two otolith organs, and the three semicircular canals through the vestibular ganglion. It relays information to the brain about balance.
2. The correct answer is option b, that is, the vestibular sense may be capable of sensory adaptation.
The awareness of the movement and the balance of the body are controlled by the vestibular system. The vestibular senses, that is, the feelings of gravitation and movement and rotation of the body originate in the inner ear. The sense organs are the cells of the hair, which transmit signals over the auditory nerve.
Answer:
The diversity-stability hypothesis
Explanation:
An hypothesis is defined as a set of idea,explanation or information that you test through study and experimentation. . A hypothesis is is broad and it is not just a random guessing but well planned theory.The stability-diversity hypothesis states that the broader a community the more okay and productive the community will be. This hypothesis drawn from a more stable and productive communities can use their resources at their disposal better and great use.
Stability as a product of variability relative to community abundance.
