Answer:
The biological part of our attraction lies in something called the major histocompatibility complex (MHC) or human leukocyte antigen (HLA) and the going theory is that opposites attract. Put another way, the more different our HLA types are from one another, the more likely we are to find each other attractive.

Velocity is The amount of time it takes an object to move from point A to point B. Therefore, option B is correct.
What is velocity?When an item is moving, its velocity is the rate at which it is changing position as seen from a particular point of view and as measured by a certain unit of time. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed). The various forms of velocities include uniform, variable, average, and instantaneous velocities.
There are countless practical uses for velocity, but one of the more frequent ones is figuring out how quickly you (or anything in motion) will get somewhere from somewhere.

The term used to describe the front of the elbow is
Answer:
Antecubital
Explanation:
In technical anatomical terms, antecubital refers to the area anterior to the elbow—meaning the opposite side. In the human body, the antecubital area is where the humerus (upper arm bone) connects to the radius and ulna bones of the forearm.
The term used to describe the front of the elbow is: Antecubital fossa
Antecubital fossa is the term used to describe the front surface of the elbow. this area is important in the human arm because it is the area where the upper arm bone connects with the bones of the forearm ( ulna and radius ).
The name Antecubital fossa is derived from the Latin name Cubitus
During the insertion of IV into the human body or during blood donation, the Antecubital area is very vital because veins can be easily located around the area than any other part of the body.
Hence in conclusion the term used to describe the front of the elbow is Antecubital.

What is the function of the surface protein on the influenza virus?
A To protect
B To attach to a host cell
C To manufacture enzymes using a host's immune system
D To remove a host cells's DNA
Surface proteins are the proteins that are embedded in the cell membrane structure of organisms and help in cell interaction with the outer surrounding or other cells.
Surface protein on the influenza virus is needed for attaching to the host cell.
The surface protein of viruses can be explained as:In viruses, the genetic material is stored in these protein structures called capsids which protects the viral genetic material from degrading enzymes and other cellular enzymatic activities.Surface proteins on the viruses are needed to penetrate and attach to the host system and cells for inducing immune response and diseases.The surface proteins of influenza virus HA and NA are necessary for penetrating host mucus layers.Therefore, option B to attach to the host cell the surface proteins are needed.

Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
