Proteins help substances cross the cell membrane during facilitated diffusion. Thus option C is correct.

Proteins are defined as large biomolecules and macromolecules and are made up of one or more extended chains of amino acid residues.

Protein play the important role in development of human body.

Proteins assist our body with cell regeneration and repair.

There are basically eight types of proteins.

Thus, proteins help substances cross the cell membrane during facilitated diffusion. Thus option C is correct.

Which of these correctly relates the photoreceptor to the region of the brain to which it connects? Photoreceptor connects to visual region

Photoreceptors can be defined as cells for detecting light. They are composed of the outer nuclear layer that contains the cell nuclei the inner segment that houses the cell machinery and the outer segment that contains photo-sensitive pigment.

Therefore photoreceptors are the only cells that can convert incoming light into an electrical signal that can be carried to the brain via the optic nerve to create conscious vision.

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

Answer:

usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.

Explanation:

The type of energy muscle cells use to produce mechanical energy in the movement of an arm is known as chemical energy.

The type of energy that muscle cells use is known as chemical energy. Adenosine triphosphate (ATP) is the energy source for all muscle contractions. Energy is released when ATP is broken into ADP+Pi (adenosine diphosphate and phosphate group).

Maintaining the availability of ATP for muscle contraction is the limiting factor since ATP is not stored in large amounts in skeletal muscle. Muscle contraction converts chemical energy to mechanical energy when ATP is hydrolyzed during cross-bridge cycling.

This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.

Therefore, chemical energy is the type of energy muscle cells use to produce mechanical energy in the movement of an arm.

-saliva

-hydrochloric acid

-pancreatic juices

Explanation:

When the food such as carbohydrates enters our mouth, the saliva enzyme starts break down of that carbohydrate. Then the food enters the esophagus and then reaches the stomach. In stomach, hydrochloric acid  is present which helps in digestion of food. Then the food enters the small intestine and their pancreatic juice is present which also helps in break down of sugars, fats, and starches.

Answer:

1. Molecular data:  

- Advantages:  

a. less susceptible to evolutionary convergence

b. huge amount of potential characters available for data comparison (each nucleotide can potentially be used to assess the state of a character)

c. useful for assessing times of divergence

- Disadvantages:  

a. multiple sequence alignments are hard to solve for sequences with high evolutionary rates

b. limitation to the number of states of the character

c. generally unuseful for comparing with data from extinct species

d. difficulties of inferring positional homology

2. Morphological data:

- Advantages:  

a. useful to understand the evolutionary significance of traits in extinct ancestral species

b. there is not limitation to the number of different states of the character

- Disadvantages:

a. susceptible to evolutionary convergence

b. limited number of characters is available

Explanation:

Morphological and molecular data are the two primary sources of information used to infer homology. In the last years, molecular data gained ground for this purpose. However, it should be stressed that molecular data only have 4 different states (i.e., 4 different types of nucleotides), while for morphological data in principle there is not limitation to the number of different states. On the other hand, morphological traits are more susceptible to evolutionary convergence, thereby leading to spurious results when assessing the homology of problematic characters. Finally, it is important to highlight that morphological data are generally more useful to understand the origin and homology of traits in extinct species.

Explanation:

Answer:

Depends on the temperature of it's surroundings.

Explanation:

Answer:

There are two reasons. One of them is that the water molecule is “bent”. It is rotationally asymmetric, meaning that it can “store” more energy in the rotational degrees of freedom than other, symmetric molecules (like diatomic molecules, or CO 2  for example).

The other and more important reason are the hydrogen bonds. When a hydrogen atoms binds with a more electronegative atom (such as oxygen in the case of water), its electron has a higher probability to be found in the vicinity of the oxygen atom, leaving the hydrogen nucleus partly “exposed”. This partial charge on the hydrogen will create a very weak bond with the partly negatively charged oxygen atom of a neighbouring water molecule (remember, the hydrogens’ electrons prefer to be around the oxygen atom instead, making it a bit negatively charged). This electrostatic interaction, or bond, between neighbouring water molecules is the famous hydrogen bond.

Even though each hydrogen bond by itself is weak compared to the bonds in the molecules themselves, there are many neighbours around each water molecule, which means that water can store a significant amount of energy in these bonds. As you add heat to water, instead of speeding up the molecules (increasing their kinetic energy and thus temperature) the hydrogen bonds get broken up, soaking in the additional heat without much change in temperature.
