Yes because the cornea in your eye takes oxygen directly from the air, not from your blood.

Answer: c. Point B has an elevation less than 2750 feet.

Explanation:

The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.

Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

Answer:

flexion

Explanation:

The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.

In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.

The flexion occurs in the sagittal plane.

Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

d

Explanation:

qualitative data is typically descriptive data

Answer:

The correct answer is - 2n = 41 chromosomes.

Explanation:

It is given that the cat has a diploid chromosome number of 38 while the rabbit has a diploid number of 44 chromosomes and if they form a hybrid then their expected chromosome number in somatic cells would be -

Cat (2n=38) produces haploid gametes with 19 chromosomes (n-19).

Rabbit (2n=44) produces haploid gametes with 22 chromosomes(n=22)

19+22= 41 chromosomes in the particular hybrid as half number of chromosomes come from each parent.

Answer:

D. Adenosine DIPHOSPHATE

Explanation:

ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy

When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.

Answer:

The correct answer is - logistic growth.

Explanation:

The growth of bats is only limited by the fruit trees they feed on. It is an example of the concept of carrying capacity of an environment, so this is best modelled by logistic growth.

The Types 1-3 of survival growth are related to age, while exponential growth does not have any limits related to environmental capacity.

The correct answer is - logistic growth.

Answer:

Tracheal, vessel or vascular cells have one or more pores in their terminal walls. They reabsorb the common walls. They adopt a vertical position and are linked together forming a continuous tube or glass. They constitute the Xylem of angiosperms, plants that have flowers, and their function is to conduct water and other nutrients.

Explanation:

The vascular elements or vessels are specialized tracheids whose terminal walls are crossed by one or more pores; a vertical series of vascular elements that form a continuous tube is called a vessel. The tracheids are cells that conduct water and salts of the xylem, through which the raw sap circulates. It is typical of gymnosperms. The tracheids are unicellular, very elongated and with numerous simple, areolate pits, through which they intercommunicate.

Answer:

Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.

Phagocytes.

Explanation:

Phagocytes are the cells which would be affected by the cancer that involved the immune cells in our central nervous system that ingest intruders. If the cells that ingested intruders also turn into cancer cells then there is decrease occur in the number of Phagocytes and the body's immune system get weaken and unable to defend the body against pathogens. Phagocytes are a type of white blood cells that use phagocytosis method to engulf bacteria, foreign particles, and dying cells to protect the body.
