Answer: A) Accretion

Explanation:-

Accretion is the accumulation of particles into a large object caused by gravitation.Most galaxies, stars, and planets are formed by accretion process.

Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.

Equilibrium is a reversible chemical reaction in which rate of forward reaction is equal to the rate of backward reaction. The concentration of the reactants and products remain constant.

Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to

Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ $RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-(-2))^2+(4-4)^2}$

⇒ $=\sqrt{(3+2)^2+(0)^2}$

⇒ $=\sqrt{25}$

⇒ $=5 \ units$

and,

⇒ $ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

⇒ $=\sqrt{(3-3)^2+(-1-4)^2}$

⇒ $=\sqrt{0+(-5)^2}$

⇒ $=5 \ units$

Now,

The total trail length will be:

= $RS+ST$

= $5+5$

= $10 \ units$

What role do nerve cells play in the human body? They allow the body to react to stimuli. They regulate the exchange of chemical

Alex

The right option is; They allow the body to react to stimuli.

Nerve cells, (also called neurons) are specialized cells that are found in their millions in the nervous system. Nerve cells are created to stimulate other cells in the body. They transmit messages in the form of electrical signals within the body, and they allow the body to respond to stimuli. Neurons are grouped into three types which are; sensory neurons, motor neurons and association neurons.
