There is a block of genes in the order ABCDEFG on a chromosome. A duplication takes place between, but not including, genes B an

anastassius [24]

Explanation:

ABCDECDEFG

Duplications involve the production of one or multiple copies of a specified region of the genetic code

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly condensed and wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes.

Duplications involve the production of one or multiple copies of a specified region of the genetic code.

Like other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.

During which step of the water cycle does water combine with pollutants on Earth's surface?

Troyanec [42]

The correct answer is option C, that is a runoff.

The water from rain, snowmelt, or other sources is known as surface runoff, it flows over the land surface, and is a prime constituent of the water cycle. Runoff, which takes place on the surfaces prior to reaching a channel is also known as overland flow. When flowing of runoff takes place along the ground, it can pick up soil contaminants like pesticides, petroleum, or fertilizers, which turn into overland or discharged flow.

The majority of neurotransmitters migrate across the synaptic gap and latch onto receptor sites of the receiving neuron's:

finlep [7]

Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.

<h3>What is a synapse?</h3>

Neurons are cells that communicate with each other through the transmition of nervous impulses.

Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.

Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.

During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.

The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.

This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.

Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.

According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.

Dendrites are the structures that receive chemical messages from the other cells.

The correct option is D. Dendrites.
