Evidence suggests that the addictiveness of some drugs, including cocaine and nicotine, is related to increases in the activity
alexgriva [62]
The answer is "Dopamine".

<span>Some drugs fundamentally influence one neurotransmitter or class of neurotransmitters. For instance, prescription opioids and heroin deliver impacts that are like (however more articulated than) those created by the neurotransmitters endorphin and enkephalin: expanded absence of pain, reduced readiness, and low breath. Different medications upset more than one sort of neurotransmitter. Cocaine, for instance, joins to structures that manage dopamine, prompting increments in dopamine activity and creating euphoria; it likewise delivers changes in norepinephrine and glutamate frameworks that cause stimulant impacts.</span>

A carbon sink is a place where carbon Select one: a. is stored after removal from the atmosphere. b. is released after cellular
sashaice [31]

Answer:

A. is stored after removal from the atmosphere

Explanation:

A carbon sink is a place where carbon is stored after removal from the atmosphere. Carbon is stored in a carbon sink when they are removed from the atmosphere.

A carbon sink are reservoir (usually natural) where carbon is stored. Carbon sink store carbon because of their ability to absorb more carbon. Examples of carbon sinks are plants and water. Plants and water has the capability to absorb more quantity of carbon from the atmosphere and release less quantity of carbon.

Carbon is a chemical elements represented by the symbol C. It has the atomic number 6 and belongs to group 14 of the periodic table.

Why might the cell theory actually be a law?
Sladkaya [172]

Due to a law being a predicted sort of event that is bound to happen every time, a pattern, we can say that since the cell theory is a pattern instead of a possible explanation, it can be a law. However, since we don't have an accurate explanation to the part which claims that they all come from pre-existing cells, it is a theory, we don't have enough information to confirm that the theory is a solid fact, therefore, we can't confirm that it is a law.

Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar
Tju [1.3M]

Answer:

Answer is option A.

Vestigial features are fully developed and functional in one group of organisms but reduced and function less in a similar group.

Explanation:

  • Vestigial structures are anatomical features such as cells, tissues or organs in an organism that are previously functional and performed some important functions in the organism but no longer serve any functions in the current form of the organism and become useless as a result of a large evolutionary change. Examples include the coccyx or the tailbone in humans, the pelvic bone of a snake, wisdom teeth in humans, nipples in human males, the wings of flightless birds such as kiwi, ostrich, etc.
  • Homologous features are the features that are similar in different organisms having similar embryonic origin and development and are inherited from a common ancestor that also had that feature. Also, they might have different functions. An example is the presence of four limbs in tetrapods such as crocodiles, birds, etc.
  • Analogous features are the features that are superficially similar in different organisms but had separate evolutionary origins i.e., different in origin, but similar in function. An example includes the wings on a fly, a moth, and a bird where the wings were developed independently as adaptations to perform the common function of flying.
  • Polygenic features are the traits or features that are controlled by multiple genes that are located on the same or different chromosomes and are also affected by the environment. These features do not follow Mendel’s pattern of inheritance and are represented as a range of continuous variation. Examples of polygenic traits or features include skin color, height, hair color, eye color, etc. For example, there is wide variation in the human skin color (from light to dark) and height (short or tall or somewhere in between).
  • Sympatry describes a species or a population that inhabit the same geographic region at the same time. In sympatric speciation, new species are evolved from a surviving ancestral species while both the species inhabit the same place at the same time i.e., in a single population, reproductive isolation occurs without geographic isolation.
