How does a Covalent Bond Form? ( No goo.gle ik the goo.gle answer cause i tryed looking it up if you put tht answer u wont get brainliest)
Answer:
A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units.

What is the name for winds that usually blow in the same direction?
Dry winds
Prevailing winds
Smart winds
Strong winds
Answer: (B) Prevailing winds
Explanation: the name for winds that usually blow in the same direction is Prevailing winds
The name for winds that usually blow in the same direction is "Prevailing winds". Therefore, option (B) is correct.
What is prevailing winds?Prevailing winds are the dominant winds that blow consistently over a region, resulting from the combined effects of global atmospheric circulation patterns, the Coriolis effect, and local geography. These winds typically blow from the same direction and have a significant impact on regional climate, as they can bring in moisture, temperature changes, and other weather conditions.
Prevailing winds can be important for agriculture, transportation, and other human activities that are affected by weather patterns. Therefore, option B, prevailing winds, is the correct answer

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.

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.

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.
