Free_Kalibri [48]

The question is incomplete. The complete question is as follows:

Select the correct answer from each drop-down menu.

Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.

Answer:

synapse

neurotransmitter

Explanation:

Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.

The neuron receives signals through dendrites and two neurons  communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.

Hence, the correct answers are synapse and neurotransmitter.

A number of marine reptiles and birds have salt glands, which have a remarkable ability to concentrate salt solutions for excret
Lemur [1.5K]

Answer:

A)100mL  B)50mL  C)The second option  D)Hypoosmotic Environment

Explanation:

The average Na concentration in the seas and oceans of the world is around 3,5% which mean that in 100 ml of sea water, there is around 3,5 grams of Na.

The weight of one mol of NaCl is 58,44 grams. For 3,5 grams of NaCl, we get 3,5/58,44 = 0,060 mol of NaCl which is 0,060x1000 = 60 mmol/100ml. According to this and the information given in the question about the secretion of the salt glands', if the average sodium concentration is 600mmol/L, we have 60*10 = 600mmol/L so it would take 100 mililiters of water to excrete.

If the average Na concentration of the salt gland's secretion were 300 mmol/L, only 50 mililiters of water would be needed to excrete the same sodium load.

The second option of secretion is hyperosmotic to seawater because the concentration is higher.

Osmoregulation is the process of balancing the amount of water and salt between the body of the organism and its surrounding environment. For salt glands to be advantageous for osmoregulation, they need to be in a hypoosmotic environment.

I hope this answer helps.

Determine which DNA technology allows for each of the following scenarios.
Ket [755]

Explanation:

A correct father is identified through the current techniques for paternity testing are using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP).

A suspect is identified using a small sample of evidence forensic DNA analysis

Forensic DNA analysis usually involves comparisons between genetic profiles extracted from biological samples collected from a specific site, object or person which is thought to be associated to a crime, in order to determine the likelihood that such samples come from a particular person
