Which best differentiates between chemical digestion and mechanical digestion? Chemical digestion happens in the small intestine; mechanical digestion happens in the mouth.

Chemical digestion involves the breaking down of food with enzymes;
mechanical digestion is breaking down food by chewing and tearing with teeth.

Chemical digestion is the breakdown of fats; mechanical digestion is the breakdown of proteins.

Chemical digestion is done only by the major structures of the digestive system; mechanical digestion is done by the accessory structures of the digestive system.

Answers

Answer 1

Answer: The answer is Chemical digestion involves the breaking down of food with enzymes; mechanical digestion is breaking down food by chewing and tearing with teeth.

Mechanical digestion means breaking down food mechanically. By chewing and tearing with teeth, food breaks down into smaller parts and no enzymes are used. Chemical digestion means breaking down food in a chemical manner. This is achieved by secreting enzymes, which break down chemical bond between food molecules.

Answer 2

Answer: The Best answer to the question stated above is "Chemical digestion involves the breaking down of food with enzymes;
mechanical digestion is breaking down food by chewing and tearing with teeth. "

Mechanical digestion prepares food for chemical digestion. It involves the chewing and mixing food with saliva, churning of food in the stomach, segmentation of intestines rhythmic local constrictions of intestine, causes mixing improves absorption. On the other hand chemical digestion breaks down complex food molecules into chemical building blocks, enzymes secreted into alimentary canal lumen.

You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype? Conduct a Punnett square with a purebred recessive plant. Conduct a test cross with a purebred recessive plant. Conduct a test cross with a purebred dominant plant. Conduct a test cross with a hybrid plant

Answers

The answer is Conduct a test cross with a purebred recessive plant.

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant.

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).

Why does a flowing-water ecosystem often support little plant life at its source? Describe how the ecosystem changes to support organisms as it flows.

Answers

There is little plant life near the source of a river or stream because due to the rapid flowing of water throughout rivers and streams plant life cannot put their roots deep into the soil because they will be uprooted by the fast flowing water

Final answer:

A flowing-water ecosystem supports little plant life at its source due to factors like minimal silt accumulation and shading. As the ecosystem flows downstream, organic material and nutrients support a food chain and adaptations enable survival and growth of organisms like leeches and trout.

Explanation:

The flowing-water ecosystem often supports little plant life at its source due to several factors. The fast-moving water results in minimal silt accumulation, making the water clear and inhibiting the growth of phytoplankton. The presence of tree cover and shading also keeps temperatures lower, further reducing photosynthesis.

As the ecosystem flows downstream, changes occur that support more organisms. Organic material and nutrients from leaves and other plants that fall into the water provide an additional source of energy. When the leaves decompose, the nutrients are returned to the water, supporting a food chain of invertebrates, which are then preyed upon by fish and other predators. Adaptations are also seen in organisms, such as leeches and freshwater trout, to survive and thrive in the fast-moving and colder waters.

Hypothesize whether prokaryotic cells might have been symbiotic before the evolution of eukaryotic

Answers

Two prokaryotes turning into a eukaryotic cell began with a process called

endosymbiosis. One large prokaryote engulfs (a process called

endocytosis) one small, aerobically respiring prokaryote. The small

prokaryote turned into a membrane-bound organelle, which prokaryotes do

not have, and like we know, only eukaryotes have membrane-bound

organelles. So that is how the eukaryotic cell structure evolved from

prokaryotic cells, meaning that before this evolution, they were most likely symbiotic.
