Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fa
Vera_Pavlovna [14]

Answer:

Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.

Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.

Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.

The following DNA is being replicated and the origin of replication is in the middle of the sequence and marked with three stars
xxTIMURxx [149]

Answer:

5'GATCGTAA3'

5'ATTCTAGA3'

Explanation:

As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.

Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.

DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.

What element is necessary for the production of thyroid hormone?
liubo4ka [24]

Answer:

Iodine

Explanation:

This is a trace element needed for the  synthesis of the two thyroid hormone ; T4- thyroxine and T3-triiodothyronine. Four iodine molecules are added in T4 synthesis, and  three for T3 synthesis. Generally T4 is the major hormone produced, but  biologically transformed into active form T3.

Iodine majorly and selenium are the two trace elements needed for thyroid hormones synthesis. Therefore required amount of iodine is important in daily diet. iIn adequate supply of this leads to under production of iodine called hypothyroidism. poor brain development ( especially in kids),and goiter.

Sea foods . eggs, poultry seaweeds are rich sources of iodine.

Conversely, when  excessive amount is present in the blood, autoimmune thyroid diseases can occur,including cancer developments in the thyroid gland due to hyper cell activities.

Complete the sentence. ____________ affects the way heat is distributed on Earth's surface.
enyata [817]

Earth's tilt on its axis affects the way heat is distributed on Earth's surface.

The Earth orbits the sun every 365 ¼ days. The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun’s energy across the surface of the planet. More tilt means more severe seasons, that is warmer summers and colder winters where as less tilt means less severe seasons, that is cooler summers and milder winters.
