Answer:
A polar bond
Explanation:
Ionic bond don't share but one atom accepts electron while the other gives away electron Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive A polar bond deals with the share of unequal electron (I.e. Covalent polar bond) A hydrogen bond is covalently bonded to highly electronegative elements of small atomic sizeA wildfire comes into an area of 300 trees and destroys all but 10 of them.
Eventually, the 10 trees will reproduce and create more trees. What is this
situation an example of?
A genetic drift
B gene flow
C bottleneck
Answer:
C, Bottleneck
Explanation:
A bottleneck effect is defined as when "A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events."
The forest fire is the enviornmental event in this situation, and the population was greatly reduced.

Which statement best describes how a diagram of photosynthesis would differ for a diagram of cellular respiration?
A. The photosynthesis diagram would show UV rays as the final product
B. The photosynthesis diagram would show water as the main source of chemical
energy
C. The photosynthesis diagram would show glucose as the main source of energy
D. The photosynthesis diagram would show radiant (solar) energy as the main
source of energy
Answer:D
Explanation:
Photosynthesis main energy source is solar energy while cellular respiration uses chemical energy
The main source of energy in the process of photosynthesis in plants is radiant (solar) energy. Plants convert this solar energy into chemical energy in the form of sugars (food). Thus, the correct option is D.
What is Photosynthesis?Photosynthesis is the phenomena by which plants prepare their food. Photosynthesis takes place in the chloroplast of green leaves. The chloroplast contains chlorophyll. Chlorophyll is the pigment responsible for photosynthesis. Chlorophyll traps the solar energy (light) in the cells which is then converted into chemical energy. The chemical energy is in the form of sugars (glucose).
In cellular respiration, the chemical energy in the form of glucose is converted into ATP (energy currency of the cell).
Therefore, the correct option is D.

When cells are damaged, new cells are created by cell a process called cell division. The cell theory supports this fact as it states that all cells have a nucleus that divides.
What is the cell theory?All living things are primarily composed of cells, which serve as both the basic structural and organizational units of all living things. According to the biological notion known as "cell theory," all cells are descended from previously existing cells. All living things are composed mostly of cells, which also serve as the fundamental unit of reproduction. The cell theory is based on the following three basic postulates: Every living thing is made up of one or more cells.The fundamental unit of structure and organization in organisms is the cell. New cells are created from pre-existing cells. Theodor Schwann and Matthias Jakob Schleiden are two scientists usually credited with developing or discovering the cell theory. In 1839, Schleiden claimed that every structural element of a plant is composed of cells or is a cell-derived substance. Additionally, he suggested that cells were created through a crystallization process that took place either inside or outside of other cells.

Coal, a fossil fuel made from the remains of swamp plants, has been found in Antarctica. Which of the following is the most reasonable explanation for how this is possible when 98% of Antarctica is now
covered in ice?
The coal was transported by animals that ate the swamp plants.
The climate of Antarctica has become milder due to its closeness to the ocean.
The climate of Antarctica was probably much warmer in the past than it is today.
The coal was transported through large convection currents and uplift in the mantle.
Answer:
The climate of Antarctica was probably much warmer in the past than it is today.
Explanation:
There are little things living there now. Coal takes millions of years to form. There must have been much more living things there in the past (when it was warmer) to make coal.

What’s the difference in concentration of hydronium Ions between pH1 and pH4?
a) x 2.6
b) x 1000
c) x 4
d) x 10
Answer:
The difference in concentration of hydronium Ions between pH1 and pH4 is 1000 times.
The difference in concentration of hydronium Ions between pH1 and pH4 is - Option b) x 1000.
pH scale is a scale or measure to find the strength of acidity or basic nature of a solution or substance. pH 1 is acidic and pH 14 is most basic on scale.
Acids combine with water molecules to form hydronium ion, H3O+. Therefore, pH formula in aqueous solution becomes-
pH = - log [H3O+].
taking antilog on both the sides, the concentration would be calculated as
[H3O+] = antilog (- pH)
In the first case, pH given is 1. So,
=> [H3O+] = antilog (- 1)
= 0.1
In the second case, pH given is 4. So,
=> [H3O+] = antilog (- 4)
= 0.0001
Thus, the concentration of hydronium ion at pH 1 is around 1000 times greater than that of concentration at pH 4.

What are desert plants?Desert flora that require water conservation Prairie plants that must withstand flames desert flora that require water, conservation thick waxy covering would most likely be a useful adaptation.
The challenge for plants that thrive in highly dry environments is finding and retaining water.
Xerophytes are plants that can survive in extremely arid conditions. Their adaptations may aid them in consuming more water, reducing water waste, or storing water for later use.
Therefore, water is so scarce in deserts, plants there need to minimize water waste. They have thin foliage that enable them to retain more water during the summer.
