Answer: Option B) It would decrease
Explanation:
Since algae is a producer, while water flea is a primary consumer; a decrease in algae infer a shortage of food for the water flea, which therefore begins Intra-specie competition that could lead to starvation and death among the water flea specie.
Answer:
D. Ticks live on and drink blood from a cow.
This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.
Explanation:
Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.
Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).
Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.
Answer: Brown
Explanation:
Co- dominance occur when the two traits(dominant and the recessive) are both expressed given rise to a phenotype that is different from the parent.
Since Brown(T) is the dominant color and it is expressed over black fur(t) an organism with Tt genotype having the two alleles will be brown fur, where the black fur will not be expressed in the phenotype and the brown expressing itself over the black.
. I think that bivalves have evolved to have smaller head regions because they have also evolved to have bigger shells or valves than cephalopod
