1. Salivary amylase is the primary digestive enzyme in the mouth. I helps to break down carbohydrates.

2. Pepsin is produced in the stomach and breaks down proteins.

3. Protease is also found in the stomach. It breaks down proteins and peptides.

4. Bicarbonate is a basic substance made by the pancreas and helps to neutralize stomach acid.

5. Bicarbonate ions to neutralize the hydrochloric acid of chyme.

6. The liver secretes bile, a digestive fluid; metabolizes proteins, carbohydrates, and fats; stores glycogen, vitamins, and other substances; synthesizes blood-clotting factors; removes wastes and toxic matter from the blood; regulates blood volume; and destroys old red blood cells.

Answer:

Carrier proteins can change their shape to move a target molecule from one side of the membrane to the other. ... The carrier proteins involved in facilitated diffusion simply provide hydrophilic molecules with a way to move down an existing concentration gradient (rather than acting as pumps).

Answer:

The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]

Answer:

Sex Cells (Sperm & Egg Cells)

Answer:

Results in the evolution of the species: Directional selection

Results in new species: Disruptive selection

Favors traits at the two extremes: Disruptive selection

No increase in diversity: Directional selection

One extreme trait is favored: Directional selection

Diversity decreases: Stabilizing selection

Diversity increases: Disruptive selection

Explanation:

Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.

Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.

While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.

Answer:  A) directional selection

                B) disruptive selection

               B) disruptive selection

               A) directional selection

               A) directional selection

               C) stabilizing selection

               B) disruptive selection

Answer:

-The sun

-shadow

Explanation:

-The sun rises in the general direction of east and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction.

-The shadow will always move - or, more precisely 'grow' in the west-to-east direction. (Before noon, when the sun is rising, the shadow will grow shorter and after noon when the sun is setting, the shadow will grow longer)

Answer:

Herbivore and carnivores.

Explanation:

This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.

Answer: electrical energy

The faster the charges move, the more electrical energy they carry. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Lightning, batteries and even electric eels are examples of electrical energy in action!Electrical energy can be either potential or kinetic energy since it's created from an electric charge flow. Continuing with the example of a battery, we know it has electrical potential energy while charging.

Explanation:

Life Cycle of a Star

Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

Answer:

Mitochondrion

Explanation:

The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.

Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers.

U already marked the correct option.

Answer: Carbon dioxide becomes a poisonous gas when there is too much of it in the air you breathe. Besides the effects it can have on the planet and the atmosphere, carbon dioxide poisoning can lead to central nervous system damage and respiratory deterioration in humans and other breathing creatures.

answer is part (C)

Explanation:

mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ

mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ. Thus the correct option is C.

What is mRNA?

Messenger RNA is referred to as a type of single-stranded RNA which involved in protein synthesis. mRNA is made from a DNA template during the process of transcription (formation of protein from DNA to RNA).

The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery ribosome reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

Explanation:

Answer: The answer is C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.

Explanation: Each baby isn't an exact clone of the parents. They share different alleles from different parents. Think about it. If the dad and mother didn't look alike then how could the baby have the same physical features as both combined. So basically, The way offspring look depends on the combinations of alleles they inherit from their parents.
