<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals.
Examples : Coral polyps and zooxanthellae
bee and flower
Lichens
Rhizobium and root nodules
Ungulates and bacteria which live in their intestines
</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.
Examples : Remora and sharks
Orchids and trees
Pseudoscorpions and Beetles
Cattle Egrets and Livestock
hermit crab and sea anemone

3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host).
Examples : <em>Cuscuta</em> (parasite)<span> and angiosperms (host)
Parasitic viruses (parasite) and human (host)
Tape worms (parasite) and pigs (host)
Flukes (parasite) and human (host)
Parasitic bacteria (parasite) and human (host)</span>
Answer:
A) Any butterfly allele that allowed milkweed toxin storage would be likely to persist because butterflies that had it were more likely to survive.
Explanation:
Butterflies are natural preys to birds. Over time, some butterflies evolved adaptive strategy such as developing an allele which enables storage of toxin from milkweed as a form of defense mechanism. This stored toxins repel birds from eating the butterflies having this allele giving rise to the survival of these butterflies overtime. Butterflies that had it are likely to be highly favored for survival against predatory birds, while those butterflies without this allele are likely to be heavily preyed upon by birds.
Answer:
c-hormonal hyperplasia
Explanation:
When there is increase in the number of cells and tissues that appear normal under the microscope,Hyperplasia is said to occur.If these occur in cells of an endocrine gland of a system,then it is refers to as hormonal hyperplasia.
Therefore during pregnancy,the proliferation of the glandular epithelium in a pregnant woman (and at puberty in a females are examples of hormonal hyperlasia.
Its possible causes are;
a surge in local production s of growth factors,
In the numbers of growth factors receptors on the cells receptive to the factors,
and due to activation of specific intrancellular signalling pathways.
D. Because an amino acid is a monomer of a protein, meaning when a bunch of them are put together it’s a protein. And so it is when a bunch of monosaccharides are put together, it makes a polysaccharide
