Answer: When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth

A mutation can effect the genes by creating new genes to pass on. Mutation happens when the pattern of a DNA chain is broken. As you might get similar characteristics from you parents (half from mom and half from dad), you can also notice many different features that they don’t have. Then, you could pass those unique features down to your kids, and further on. I hoped that helped! :D

If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?

oksian1 [2.3K]

The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.

Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?

expeople1 [14]

Answer

a balance and a graduated cylinder

Explanation

Density is mass per unit and it is property characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.

For a student to measure the density of seawater he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample and then a graduated cylinder to determine the volume.

Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH releas

inn [45]

Question: Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

(A) As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

(B) As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine.

(D) As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine.

Answer:

As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

Explanation:

ADH is the hormone that triggers the formation of concentrated urine by stimulating the absorption of water from the filtrate in the kidneys. As the solute concentration (osmolarity) in the blood raises, the more of the ADH is released into the blood. ADH triggers reabsorption of water in collecting duct and distal tubules and thereby, reduces the water loss in urine. Increased reabsorption of water restores the osmolarity, blood volume, and blood pressure.
