Match each type of association with the best example commensalism mutualism parasitism amensalism A. A mold produces a chemical

Brums [2.3K]

A. A mold produces a chemical that kills bacteria without apparently benefiting. - amensalism

B. Aerobic bacteria in the human colon consume oxygen, making it possible for anaerobic species to survive. - commensalism

C. "Flagellates live in the gut of termites, feeding on the wood consumed by the termite and allowing the termite access to nutrition and energy in wood that they could not otherwise digest" - mutualism

D. "A helminth takes up residence in a human digestive tract, consuming nutrients" - parasitism

Explanation:

Amensalism is any relationship between organisms of different species in which one organism is inhibited or destroyed while the other organism remains unaffected.

Two examples of antibiosis amensalism are provided by the bread mold Penicillium and black walnut trees.

Amensalism is the association between organisms of two different species in which one is inhibited or destroyed and the other is unaffected.

Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed.

Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction.

parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm, and is adapted structurally to this way of life

Examine how the circulatory and respiratory system work together to move oxygen through the body.

Ksju [112]

Answer: The respiratory system works directly with the circulatory system to provide oxygen to the body. Oxygen taken in from the respiratory system moves into blood vessels that then circulate oxygen-rich blood to tissues and cells.

Give the sequence of mRNA that would match the following DNA strand

sladkih [1.3K]

Answer:

Below

Explanation:

mRNA is a complimentary copy of a DNA segment (gene) and consequently can be used to deduce the gene sequence. For converting a sequence from mRNA to the original DNA code, apply the rules of complementary base pairing: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A).

The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain. The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

A large population of yellow perch lives in the east river. the walleye is a larger fish that eats the yellow perch. despite lot

loris [4]

The lack of adaptations to the habitat most likely caused the walleye to move to a different river.

Adaptation

It is a biological mechanism that increases the chance of its survival in a new environment or the changes in the existing environment. Adaptation occurs as a result of evolution and allows the organism to survive and reproduce efficiently in its environment.

Physical adaptations include accumulating changes in the physical characteristics of an organism that help them to survive and reproduce better. Example: evolution of long necks in giraffes.

Behavioral adaptations are changes in the behavior or habits of organisms that help them to sustain in a changing or new environment. Example: Hibernation.

Due to some reason, the walleye were not able to adapt to the environment of the east river which is why they must have moved to a new river despite the presence of a lot of prey.
