Which materials are moved by runoff?
Answer: Gravity causes the water to flow downhill. As the runoff flows, it may pick up loose material. These materials may include bits of soil and sand. It is carried off by this running water across the surface of the land.
Which of the following adds oxygen to the atmosphere?
A.forest fires
B.the weathering of rocks
C.photosynthesis
D.life processes of animals
Helppppp I will make brainliest
The process of photosynthesis adds oxygen to the atmosphere. Option C is correct for the given statement. In the atmosphere, nearly 21% oxygen is present.
What is the gas constituent of the atmosphere?In the atmosphere, different gases such as oxygen, nitrogen, carbon dioxide, and water vapour are present. These differ in composition, with oxygen accounting for 21%, nitrogen accounting for nearly 78%, and carbon dioxide accounting for less than 1%.
The oxygen is produced by the process of photosynthesis that is undertaken by green plants. The phytoplankton, algae in aquatic habitats, and plants of the terrestrial ecosystem do photosynthesis because of the presence of chloroplasts.
This oxygen is used by animals and plants for cellular respiration. Others are incorrect options because forest fires increase carbon dioxide in the atmosphere, animals take oxygen from the atmosphere, and rock weathering does not add oxygen.
As a result, option C is the correct answer because photosynthesis produces oxygen for the atmosphere.

If a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, the ball will:
A: move to the right with the same speed
B: move to the left with the same speed
C: be forced vertical with the same speed
D: continue with the same velocity
there is one correct answer
If a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, the ball will continue with the same velocity.
What is a balanced force?A balanced force occurs when the opposing forces acting on an object is equal.
According to Newton first law of motion, a body will remain at rest until it is acted upon by an external force.
However, a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, this means that a balanced force is acting on the object, hence, will move at the same velocity.

The endocrine system consists of ________
A)
association areas.
B)
neural networks.
C)
interneurons.
D)
glands.
Answer: The endocrine system consists of Glands.
The glands that make up the endocrine system produce chemical messengers called hormones that travel through the blood to other parts of the body. Important endocrine glands include the pituitary, thyroid, parathyroid, thymus, and adrenal glands.The endocrine system is made up of the endocrine glands that secrete hormones. Although there are eight major endocrine glands scattered throughout the body, they are still considered to be one system because they have similar functions, similar mechanisms of influence, and many important interrelationships.Please Brefly describe how vaccines work and they help our immune system?

Is a pig crossed with a chimp possible, I just read an article about this and the person who had the idea was someone with the last name MCkarther PH.D. it made the news.
Answer:
The cross between two different species is called hybridization. The truth is that, for hybridization to occur, the species in question must have a certain kinship with each other, that is, they must belong to the same family of animals. An example is the cross between tigers and lions, pigs and wild boars, donkeys and donkeys, etc. Now, if there is no such familiarity between species, the truth is that hybridization will not be possible, which is the case of pigs and chimpanzees with each other.
