Answer:
A river forms from water moving from a higher elevation to a lower elevation, all due to gravity. When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. In most landscapes the land is not perfectly flat—it slopes downhill in some direction.
Lakes can be formed when glaciers melt, craters from meteorites or rivers.
springs when rainwater or groundwater is heated by magma underneath Earth's surface.

Which element matters least in the process of natural selection?
Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:
1. Organisms must display variation.
2. A trait must increase reproduction.
3. A trait must directly affect metabolism.
4. A trait must increase survival.
5. A trait must be able to be passed on to future generations.
Answer:
The correct answer is : option 3. A trait must directly affect metabolism.
Explanation:
The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.
This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.
Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.
Enzymes are biological catalysts. Which statement about enzymes is NOT correct?

Enzymes always have a specific shape.
B
Enzymes are destroyed after they are used.

In a chemical
compound, what things are being
put together?
The different atoms are being put together in a chemical compound.
What is a Chemical compound?A chemical compound may be defined as any form of substance that is composed of similar types of molecules comprising atoms of two or more chemical elements. These compounds have specific characteristics based on their appearances and chemical structure.
These different atoms are linked together covalently to each other in a linear or somehow branched chain in order to construct chemical compounds. Such chemical compounds are derived as pure substances.
Chemical compounds are derived in such a way that when two or more elements of either similar or diverse characteristics are combined through a chemical reaction. Such types of compounds are definitely formed with the help of numerous chemical bonds.
Therefore, the different atoms are being put together in a chemical compound.

Analyze the model of the cell membrane below. Which of the following statements is true about the phospholipid components of the cell membrane? Both components of the phospholipids are hydrophobic. Both components of the phospholipids are hydrophilic. The tails are hydrophilic while the heads are hydrophobic. The tails are hydrophobic while the heads are hydrophilic.
Answer:
This question appears incomplete but The correct option is the last option
Explanation:
Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.

Answer:
a) x4 b) Eyepiece x10 Objective x40
Explanation:
a) x4 magnification
The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.
b)
Eyepiece Lens: the lens at the top of the microscope that you look through. The eyepiece is usually 5x, 10x or 15x power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.
To get 400 we need to use a combination that, multiplied together, will give us 400.
If the eyepiece lens is 10x then 400/10 = 40
So if we use the 10x Eyepiece lens with the 40x Objective Lens we will get a total magnification of x400.

O sand
O dogs
PLEASE HELPPP
Answer:
sand :)
Explanation: Because leaves and dogs have cells but sand isn't made of cells but it is made of chemicals. Sand is not a living thing but leaves and dogs are .
Answer:
Sand
Explanation:
All living things are made up of one or more cells.
Leaves are plants and dogs are animals. Plants are animals are living things, therefore they must have cells.
Sand is made up of rocks and minerals that have been broken down into small pieces. Sand is not living, so it doesn’t have any cells.
Therefore, the correct answer is sand. Sand is not alive and has no cells.
