Give the sign of the electrodes and the reaction that occurs at each for both voltaic and electrolytic cells.

1 answer:

7 0

In a voltaic cell, electrons flow from the anode to the cathode. Anode is negative while cathode is positive.

In an electrolytic cell, electron flows from the cathode to the anode. Anode is positive and cathode is negative.

For both, Oxidation occurs at the anode and Reduction occurs at the cathode.

Did the Florida Panther become endangered because of natural selection, genetic drift, or gene flow?

Natalija [7]

Answer:

ALL OF THE ABOVE

Explanation:

Genetic Drift are the changes in allele frequency of a population that result from RANDOM survival or reproduction of individuals with certain characteristics. Survival or reproduction of those individuals in the face of some environmental change is a matter of LUCK or CHANCE, not because of their phenotype or genotype.

While in Natural selection, the environmental events that affect a population are likely random, but the survival or reproduction of the individuals depends on their phenotypes and genotypes.

Meanwhile, Gene flow is the movement of genes into or out of a population. Low gen flow can lead to low genetic diversity.

Low population which can cause low genetic diversity, poor habitat conditions and habitat loss, road deaths, and commercial development in panther range are constant threats to the Florida Panther's survival.

All these causes are related and therefore affects the Florida Panther.

Andrew is lactose intolerant. what happens to water movement in the presence of the double sugar, lactose, which remains in the

Juli2301 [7.4K]

When someone is lactose intolerant, it means its intestine cannot absorb lactose, which will stay in the lumen and be consumed by intestinal bacteria and produced gases, that's why intolerant lactose people have flatulence and abdominal pain while eating food with lactose in it.
Let's go back to the question, before being consumed, lactose in the lumen intestine will attract water from the enterocytes to its side by oncotic pressure.

Do not confound oncotic pressure (which concerns macromolecules like sugar or proteins) and osmotic pressure (which concern micromolecules like small ions (sodium potassium and chloride...)).

How does capillarity help sustain life? a. plants use capillarity to move water from their roots to their leaves. b. capillarity

bazaltina [42]

Answer:

Explanation:

Plants and trees couldn't thrive without capillary action. Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it's way all the way up to the branches and leaves.
