Answer: mRNA
Explanation:
is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
The answer is option D "test the effect of cyanide on algae." Ecologist are researchers who study how organisms interact with their environment so in this case they are testing how algae reacts to cyanide. In another example they will be testing how a ape reacts to having a different fruit tree in their habitat. It wouldn't be option A, B, and C because you have to remember the job of a ecologist and the options are not jobs of one.
Hope this helps.
Answer;
-Applied research
Explanation;
-Applied research is a methodology used to solve a specific, practical problem of an individual or group.
-This type of research plays an important role in solving everyday problems that often have an impact on life, work, health, and overall well-being. Applied research is used to find solutions to everyday problems, cure illness, and develop innovative technologies.
Neurotransmitters are chemical messengers that are released from the neurons during the synapses to transmit data to neighboring cells. Different neurotransmitters are responsible for various functions in the neurons .
Dopamine is a neurotransmitter that is the power driver for all the key function behind all the actions and interpersonal relationships. Dopamine is the chemical that reinforces a pattern, habit, establishing a belief and feelings like encouragement and reward which are the most basic factors for developing of relations, wanting, dedication and motivation. Hence Dopamine is the neurotransmitter that takes care of the process of reinforcement.
The process of passing genetic material from one generation to the next depends completely on how cells grow and divide. To reproduce, a simple organism such as bacteria or yeast simply copies its DNA (through a process called replication) and splits in two. But organisms that reproduce sexually go through a complicated dance that includes mixing and matching strands of DNA (a process called recombination) and then reducing the amount of DNA in special sex cells to arrive at completely new genetic combinations for their offspring.
There are two basic kinds of organisms — ones with a nucleus and those without a nucleus (a compartment filled with DNA surrounded by a membrane called a nuclear envelope):
<span>Prokaryotes: Organisms whose cells lack a nucleus and therefore have DNA floating loosely in the liquid center of the cell. Prokaryotes divide, and thus reproduce, by simple mitosis.</span><span>Eukaryotes: Organisms that have a well-defined nucleus to house and protect the DNA. Eukaryotes divide by meiosis for sexual reproduction.</span>
