which type of relationship exists when a certain type of trees roots need a fungus present in order to grow normally

Answers

Answer 1

Answer: This is a symbiotic relationship called commensalism if the tree root is the only one to benefit.

Name two ways that living things use proteins

Answers

Proteins catalyze reactions, part of the immune system, transport molecules such as oxygen, and transmit messages from cell to cell.

What is protein?

Proteins are very large molecules made of basic units known as aminoacids. Proteins consist of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sulfur (S).

Protein molecules are produced by twisted and folded strands of amino acids. Proteins are actively involved in the most important as well as basic aspects of life. These include metabolism, cellular communication, movement, molecular recognition, and defense.

The shape of structural proteins allows them to form essential structures of the body. Collagen holds most of the body tissues together, a protein with a fiber shape. Structural protein Keratin creates a network of waterproof fibers on the outer layer of the skin.

The shape of functional proteins enables them to contribute to the chemical processes of the body. Functional proteins include cell membrane receptors, hormones, growth factors, and enzymes.

9. In a period, do the number of shielding electrons change? Why do you thinkor shielding electrons change? Why do you think atomic radius decreases across a
period?

Answers

Answer:

The nuclear charge increases, but the number of inner shielding electrons stays the same.

Explanation:

Their shielding does not change, so the effective nuclear charge — the charge felt by a valence electron — increases.

The valence electrons are pulled closer to the nucleus, decreasing the atomic radius.

For example, consider the elements of Period 3.

$\begin{array}{ccccc}& & \textbf{Number of} & \textbf{Inner} & \textbf{Valence}\n\textbf{At. No.} & \textbf{Symbol} & \textbf{Protons} & \textbf{Electrons} & \textbf{Electrons}\n11& \text{Na} & 11 & 10 & 1\n12& \text{Mg} &12 & 10 & 2\n13& \text{Al} & 13 & 10 & 3 \n14& \text{Si} & 14 & 10 & 4 \n15& \text{P} & 15 & 10 & 5\n16& \text{S} & 16 & 10 & 6\n17& \text{Cl} & 17 & 10 & 7\n18& \text{Ar} & 18 & 10 & 8 \n\end{array}$

The number of protons increases as you go from one element to the next, but the number of inner electrons is constant.

How would you describe the change in the arrangement of particles as heat energy and temperature increase?

Answers

The change in the arrangement of particles as heat energy and temperature increase because of the increase in the kinetic energy of the particles.

How kinetic energy calculated?

Kinetic energy of any atom is calculated as:

K.E. = 1/2(mv²), where

v = velocity and m = mass

So, when we apply heat energy or increase the temperature of any system then the energy of the constitute particles is also increases which results in the increase of the average kinetic energy of the particle. Due to this kinetic energy particle will move with high velocity and disturbs the arrangement of the system.

Hence, due to increase in average kinetic energy, arrangement of the particles changes.
