Answer:
B: They are specialized
Explanation:
Multicellular organisms contain specialized cells which can perform more functions than unicellular organisms.
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.

Answer:
Gene flow would decrease as a result of the alteration of migration patterns. Therefore, the variability of this species would decrease.
Explanation:
Gene flow refers to the<u> transfer or introduction of genes from one population to another</u>. Gene flow enables the introduction of new alleles, therefore increasing biodiversity.
The rate of gene flow between groups of species depends on different factors. For instance, gene flow increases with the ability of a species to move from one place to another and, at the same time, on the possibility of migrating species mating with resident species. This occurs not only with birds but even with humans, when they migrate from one country to another, which increases diversity and variability.
Therefore, <u>if the migration patterns of birds that pollinate a plant species from South America is altered, then there would be less variability within this plant and also with this bird species.</u>
