Answer:
Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.
According to the law of segregation, the two alleles of a gene segregate during the time of gamete formation and there are 50-50% chances of each of the alleles to be received by the gametes. Hence, there are 50% chances for Y gametes to be produced and 50% chances for y gametes to be produced.
Answer:
<em>e. speciation</em>
Explanation:
The definition of speciation is: the evolutionary process by which populations evolve to become distinct species.
In this scenario, the bears that were once of the same species evolved in order to adapt to their environment. Once they evolved, they could no longer produce with each other, as they are now different species.
Answer:
Because Without Earthquake Research Earth Will Be DESTROYED
The best answer would be enzymes since they are protein molecules and help build it. Enzymes also take part in reaction.
Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the <u>transport system</u>. There are <u>specialized transporter proteins in the vesicle membrane</u> that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.
