When we say an animal has an "open circulatory system," this means that: movement of the animal is solely responsible for moving

circulatory fluid. a small amount of blood may leak out of vessels. there are no vesselsblood simply fills all spaces inside the coelom. the animal has a single-chambered heart, so blood mixes from all areas. blood flows out of vessels and into spaces or sinuses?

An open circulatory system simply means that the blood flows out of vessels and into the spaces or sinuses. Invertebrates, insects and crustaceans has an open circulatory system where pump blood goes into a hemocoel and diffusing back to the circulatory system between cells. In other animals, the heart pumps the blood into the body cavities, spaces or sinuses, where the blood surrounds the tissues.

Use the following terms to describe in detail how you visually perceive an object that you can see right now.

Answer: To see for example an apple first light that passes through the pupil is eventually reflected on the pupil, activating neurons in the retina. light waves that were reflected off the apple are changed into neural impulses (transduction) at the point of the retina, where neurons fire in response to light waves. Action potentials are released when neurons fire, sending an electrical charge through the neuron. Excitatory neurotransmitters are released when the action potential reaches the axon terminal, and that these neurotransmitters increase the chances that the next neuron will fire. Of course the neural message from the retina first passes through the thalamus, and then the thalamus routes the impulse elsewhere in the brain.

I hope it helps, Regards.

Answer:

Circulatory system remove waste from the cell and provide clean blood to the cell.

Explanation:

During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.

What if a mutation caused a change in the code so the message read GAG instead of GAC? 
How would this affect the protein produc
Anarel [89]

Answer: There will be no effect on the protein produced

Explanation:

According to the genetic code, the triplet codon GAG code for the amino acid, glutamate, while GAC code for aspartate.

Since GAG and GAC code for amino acids with similar properties (aspartate and glutamate are both acidic amino acids due to the extra carboxyl group present in their side chain), the change in nucleotide is still similar to the original, so will result in a different amino acid sequence, but will not alter the function of the protein at all. Thus, this kind of mutation is called silent mutation.

The binding of the neurotransmitter to receptors on the motor end plate causes which of the following to occur?
dmitriy555 [2]

The correct answer is: D) Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.

The motor neuron cell is connected to muscle cell via synaptic cleft, where neurotransmitter is released. The muscle side of this synapse is called motor end plate. Released neurotransmitter is acetylcholine and it binds to its receptor (ACh receptor) on the motor end plate. As it binds, ion channels open, and Na+ gets into the muscle cell. This event reduces the voltage difference between the inside and outside of the cell and causes  depolarization which creates a wave through the entire muscle cell (its membrane-sarcolema). As a consequence, Ca2+ is released from the sarcoplasmic reticulum which will cause the contraction of the muscle cell.
