When the Barrel and Saguaro cacti absorb moisture they store it _______. a. in their roots b. in their spines c. in the flesh of their barrels d. in underground root nodules

Answers

Answer 1
Answer:

The right answer is c. in the flesh of their barrels

The globular and massive forms perfectly fulfill their role of storing the water in their thick cuticles, but in return will expose the plants to lethal overheating due to the small surface of heat exchange with the ambient air to evacuate the heat. from exposure to the sun.

Answer 2
Answer: C. The answer is c, because if you ever slash a cacti with a sword water will come out if it is hydrated. You don't need to cut the roots just the flesh of their barrels

What do we mean when we use the terms monohybrid cross and dihybrid cross? A) A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents.
B) A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny.
C) A dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid cross involves only one.
D) A monohybrid cross is performed for one generation, whereas a dihybrid cross is performed for two generations.
E) A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio.

Answers

The answer is C) A dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid cross involves only one.

A dihybrid cross considers two traits, while a monohybrid cross considers one trait to be inherited.
The other statements cannot be true because of the following:
A) Both monohybrid and dihybrid cross involves two parents.
B) There is more than one progeny in both 
monohybrid and dihybrid cross, and the number depends on parental genotypes.
D) Both 
monohybrid and dihybrid cross are performed for two generations.
E) 
A monohybrid cross results in a 3:1 ratio whereas a dihybrid cross gives a 9:3:3:1 ratio.

Ethyl alcohol and carbon dioxide are the end products of _________.

Answers

Answer:

Alcoholic fermentation

Explanation:

Some bacteria and yeasts get energy by fermenting sugars, this reaction has as its end product ethyl alcohol and carbon dioxide (CO2), this process is called alcoholic fermentation.

Alcoholic fermentation occurs as follows: in order to react, each glucose molecule initially consumes 2 ATP to be activated. When this occurs, the glucose molecule begins to undergo various reactions until it gives rise to two molecules of pyruvic acid.

In the course of these reactions, enough energy is released to recompose 4 ATP. Each pyruvic acid molecule then decarboxylates to ethyl alcohol or ethanol.

After all these processes, the energy balance of alcoholic fermentation is: 4 ATP produced minus 2 ATP consumed to activate glucose, resulting in abalance of 2 ATP.

Human beings use alcoholic fermentation products mainly for the production of alcoholic beverages, where ethyl alcohol acts, and bread, considering that the release of carbon dioxide causes the dough to grow.

I believe the answer to this question is alcohol fermentation.

The ability of a muscle to exert force is:a. strength
b. endurance
c. fitness
d. flexibility

Answers

The ability of a muscle to exert force is: a. strength.

What is muscular strength?

Muscular strength refers to the ability of a muscle to exert force on an object. For example, if a person can strike a surface very hard, then, they would be exhibiting muscular strength. People can build muscular strength through push-ups, cycling, climbing, etc.

Muscular strength can also be developed by regularly building one's fitness through exercises that build vigor and endurance. A person with adequate muscular strength can move and lift objects with a lot of ease. So, the option, of muscular strength is right.

A scientist claims that volcanic eruptions caused dinosaurs to become extinct at this location. Decide whether you agree or disagree with the scientist's claim and then explain your decision.

Answers

Answer:

Dinosaurs are the extinct organisms that belong to the class reptilia. Dinosaurs are the most advanced and bulkier reptiles at the history time and they were overspecialized in their environment.

The dinosaurs extinct rapidly due to the change in the external conditions and the volcanic eruptions that occur at the dinosaurs time. The recent searcher claims that asteroid impact and massive volcanic eruption leads to the dinosaur extinction. The fossil evidence and the presence of the specific basalt and other chemicals are found in the volcanoes and in the asteroid.
