Answer:The target cells of neurons include other nerve cells in the brain, spinal cord, and autonomic ganglia, and the cells of muscles and glands throughout the body.
Explanation:please give braineest
Answer:
A nerve is formed by a bundle of many neurons. Neurons develop from the neural tube of the early embryo and in many animals continue development until sometime after birth. The development of motor neurons that have elongated axons is best understood. These cells are derived from tissue on the ventral side of the neural tube.

Mitosis is responsible for growth, repair, and maintenance in an organism because
Answer:
Explanation:
This is because mitosis produce two daughter cells that are genetically identical to each other thereby producing new cells that are particular to different tissues thereby making it to grow. These new cells that are genetically identical replaced the old or damaged cells , it's repair and also help in healing process.

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation of reptiles except for birds. The reptiles have a three-chambered heart that consists of two atria and one ventricle with an incomplete septum. There are two circuits: pulmonary and systemic. In the pulmonary circuit, the blood from the right ventricle is pumped in to lung capillaries and returned to the left atria. In the systemic circuit, the blood is pumped from the left ventricle to the systemic capillaries via the left systemic aorta and is then returned to the right atria. There is also one vessel going from the right ventricle to the aorta right before it branches to smaller arteries. This vessel carries mixed blood. All blood on the right side of the circuits is venous and all blood on the left side is arterial. Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart. The three-chambered heart is inferior to the four-chambered hearts of birds and mammals, limiting the evolutionary success of amphibians and nonbird reptiles. Pulmonary and systemic blood fully mixes in the ventricle of a three-chambered heart.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
Therefore, the statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.

After using a chemical mutagen to generate mutations in a dna sequence, scientists noted a mutation from c to t at the 10th position within the coding region of a gene. this mutation led to a change of proline into serine at the fourth position in the resulting peptide. using this information and the sequences listed below, select all the types of mutations that occurred.
Answer:
substitution, missense mutation, and transition
Explanation:
A mutation is any change in the genetic information of an organism. A substitution is a point mutation by which a single nucleotide base pair is replaced by a different nucleotide. Moreover, a missense mutation is a point mutation that results in the incorporation of a different amino acid in the polypeptide chain since this mutation generates a new codon which codes for a different amino acid. Finally, a transition is a point mutation where a purine (either Adenine or Guanine) is changed to another purine, or a pyrimidine (either Thymine or Cytosine) is changed to another pyrimidine (in this case, Cytosine is changed to Thymine).

In your own words, describe how the time required for digestion can be used to determine the time of death.
Answer: Backdating the time required for food found in the stomach of the deceased to digest. Since digestion can't continue after death.
Explanation: The time taken for food to get digested can be employed to depicts time of death. This process involves understanding the period of time that usually takes the food found in the gastric of the deceased to calculate the time of death.
Different foods has varying time of digestion, so therefore, the gastric content is a good indicator to determine time of death by the doctor who is carrying out autopsy, since digestion does not continue after death.
However, it is established by scientist that food takes up to 4-6hours in the stomach depending on the size and type of food. Hence, if the status of the food found in the deceased stomach is noted accordingly and the time taken requires for digestion is also noted، the doctor can deduce the time of death accordingly from this two points.

How is the ocean affected by the releasing of excess carbon?
Answer:
Explanation:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
