Define the four major types of symbiosis?

Biology
2 answers:
Ainat [17]3 years ago

Answer:

There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition. To explore these relationships, let's consider a natural ecosystem such as the ocean. Oceanic environments are known for their species diversity

Answer:

Mutualism - An interaction between two organisms in which both organisms benefit from.

Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.

Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm to the host

Mimicry - imitation of another organism for survival

Explanation:

First lets define symbiosis

Symbiosis : Interaction between two organisms predominantly to benefit one or both of the organism

Now lets find the 4 types of symbiosis

The four major symbiotic relationships include mutualism, commensalism,  mimicry and parasitism

Now lets describe/define each symbiotic relationship

Mutualism - An interaction between two organisms in which both organisms benefit from.

An example would be sharks and remora fish. Remora fish keep the water fairly clear of scraps around the shark which prevents the development of unhealthy organisms resulting in a healthy shark. In return remoras receives a fairly convenient food source and they receive protection.

Commensalism - An interaction between two organism in which one organism benefits from and the other organism neither benefits nor gets harmed.

An example would be frogs and plants. Frogs use plants for protection and the plants way of life does not change in any way

Parasitism - An interaction between a parasite and an organism. In this interaction the parasite lives inside of the organism and causes potential harm

An example would be fleas and dogs. Fleas live off of the blood in the organism (the dog in this case). Consequently the dog experiences hair loss, scratching, and irritated skin.

You are studying two species of tree frog. The two species are found on two different islands, separated by 200 km of ocean wate
Delicious77 [7]

You are studying two species of tree frog. The two species are found on two different islands, separated by 200 km of ocean water. Species A lives on very light-colored rocks and species B lives on dark-colored trees. Which process is most unlikely to be affecting allele frequencies in the population?

a. Gene flow between populations

b. Genetic drift

c. Natural selection

d. Mutation rates

Answer:

a. Gene flow between populations

Explanation:

Gene flow between two populations occurs when one or a few members of one population migrate into the other and interbreed in the new population. This process adds some new alleles to the new population. In the given example, two populations of a tree frog are separated by 200 km of ocean water. Therefore, the frogs of one population would not be able to migrate into the other population and interbreed. So, gene flow can not affect the allele frequencies of these two populations.

Which best describes the life cycles of moss and angiosperm?
jonny [76]

Ans. Option (IV).

Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.

Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.

Thus, the correct answer is option (IV).

In cattle, roan coat color (mixed red and white hairs) occurs in the heterozygous (Rr) offspring of red (RR) and white (rr) homo
antoniya [11.8K]
The answer is B) roan x roan.

Let's summarize:
R - dominant allele,
r - recessive allele,
<u>RR </u>- dominant homozygous with <u>red color</u>,
<u>rr </u>- recessive homozygous with <u>white color</u>,
<u>Rr </u>- heterozygous with <u>roan color</u>.

If we cross two heterozygous (Rr):

Parents:         Rr     x     Rr
Offspring:      RR   Rr   Rr   rr

then, the offspring will be: <u>1 red</u> (RR) : <u>2 roan</u> (Rr, Rr ) : <u>1 white</u> (rr).
