Lantern fish live in the middle ocean depths where there is no sunlight. which example is a response to this dark environment? q
densk [106]

Answer:

A lighting producing organ to attract mates and prey.

Explanation:

Camouflage would do very little for a fish that spends most of it's day in the middle of a dark ocean. Mimicking other deep sea creatures would actually be more of a disadvantage than an advantage, as the sounds would be more likely to scare away potential prey, rather than attract them. A light however, would attract the prey's curiousity and urge them to check out the light.

Explain why fossil evidence is consisten<br> with the scientific theory of evolution.
-BARSIC- [3]

Answer:

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.

Very low concentrations of detergent make membranes leaky to small molecules and ions without damaging proteins. In isolated mit
Grace [21]

Options

A. Yes, because all enzymes and electron carriers are functional

B. No, because with a leaky membrane, the proton gradient cannot be maintained

C. No, because leaky membranes inhibit glycolysis

D. No, because leaky membranes do not allow NADH and FADH2 to donate their electrons to the electron transport chain

Answer:

B. No, because with a leaky membrane, the proton gradient cannot be maintained

Explanation:

The proton motive force (PMF) provides the needed pump  to generate electrochemical gradients of proton needed for continue influx  into the matix of the mitochondria. The proton Influx generates the energy needed by  protein ATPase Synthase for  synthesis  of ATPs by adding inorganic phosphate to ADP to give ATP.

               ADP + Pi -----------→ ATP.

If the mitochondria;l  intramembrane leaks, then the PMF can  not be sustained, therefore electtrochermical gradient which supplies the energy for ATP synthase for ATP synthesis will not be available. Therefore ATP synthesis stops.

Which process temporarily disrupts homeostasis because it increases an already high concentration of chemicals in the cell?
devlian [24]

When cells in a body are not working properly and normally, they cause disruption in the body homeostasis.

Homeostatis is characterized as balance in the body but when there is any disturbance in the body, it breaks down the balance and cause imbalance. For example in the case of diabetes in which body fails to maintain the good amount of glucose in blood which results in imbalance the body which is why diabetic patients are asked to maintain and monitor their body sugar level to maintain homeostatis.
