Genetic variation is inherited by offspring.
A. Artificial aelection
B. Natural Selection
C. Both
Answer:
Both
Explanation:
A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population. Examples of genetic variation in plants include the modified leaves of carnivorous plants and the development of flowers that resemble insects to lure plant pollinators. Even though in artificial selection, you take which genes are desired it is still passing genetic variation through offspring.

pls help!!! osmosis help needed!!
Answer:
1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic
Explanation:
1. Given the image, it shows there is 10% glucose outside the cell.
2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)
3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.
2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.
3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).
3. The cell will swell, since water is getting moved in.
6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.
Hopes this helps!^^ I tried the best I could at explaining.
Which of the following would likely move through the phospholipids of the
cell membrane most easily? *
CO2
Glucose
K+
Starch
Answer:
CO2
Explanation:
Oxygen and CO2 can move through the cell membrane through simple diffusion because they are small molecules.
It's possible that CO2 travels through the lipid bilayer far more quickly than any other molecule. Therefore, option (A) is correct.
What is the structure of cell membrane ?According to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Therefore, small and simple molecules like water, H2O , CO2 can pass through the cell membrane easily as it is partially permeable.

Dave was observing two types of cells mounted on two different microscopic slides 'A' and 'B'
under the microscope. When he had observed the slide 'A' he noticed a large vacant space in the
cells and a dense round body located at one side of the cell. When he had observed the slide 'B',
there was no vacant space in the cell and he noticed a dense round body in the centre of the cell.
a) Identify the type of cell 'A' and 'B'.
b) Name the round dense structure seen in the cell.
c) Write the function of the round dense structure that he observed in the cell.
ans this please
will mark brainliest .
Answer:
The correct answer is -
a) A plant cell B animal cell
b) nucleus
C) Vacuole
Explanation:
In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.
In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -
a) A plant cell B animal cell
b) nucleus
C) Vacuole

What is the dynamic of type 1 diabetes process concerning cellular disruption and what is its effect on the major body systems?
Please help, will give brainliest
Explanation:
Type 1 diabetes occurs when some or all of the insulin-producing cells in the pancreas are destroyed. This leaves the patient with little or no insulin. Without insulin, sugar accumulates in the bloodstream rather than entering the cells. As a result, the body cannot use this glucose for energy.
In most people with type 1 diabetes, the body's immune system, which normally fights infection, attacks and destroys the cells in the pancreas that make insulin. As a result, your pancreas stops making insulin. Without insulin, glucose can't get into your cells and your blood glucose rises above normal.18-

Which best describes the way a sound wave is sent through the radio?
sound wave → radio wave
radio wave → sound wave
radio wave → sound wave → electrical signal → sound wave
sound wave → electrical signal → radio wave → sound wave
Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.
What is a sound wave?A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.
The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.
These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.
Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

a: excessive growth of algae b: increased bacterial growth c: decrease in oxygen levels d: all of the above
Answer:D,C,
Explanation:
Q1)Trees increase the ability of the soil to retain stormwater by absorbing water from the ground. The roots also help to break up compacted soil as they expand, allowing water to flow more easily downward into the groundwater level.
Q2) The Sun's energy drives the water cycle. The sun warms the ocean's surface and other bodies of surface water, allowing liquid water to drain and ice to sublime (transform from a solid to a gas). These solar-powered processes release water vapor into to the atmosphere.
