Which of the following best describes the cytoplasm in the cell?
a watery substance where cell processes take place
a hard substance that digests food molecules
a watery substance that keeps molecules from leaving the cell
a hard substance that keeps the cell rigid
Answer: A watery substance where cell processes take place.
Explanation: Process of elimination. The 2nd and last answer choices are both immediately wrong because cytoplasm is not a hard/solid substance. And the third answer choice is wrong because the cell membrane’s job is to prevent organelles from leaving the cell, not the cytoplasm. Therefore the answer is A, a watery substance where cell processes take place.
It is a jelly-like liquid that surrounds everything inside the cell.

What's the difference between monosomy and trisomy?
Answer:
Trisomies and monosomies are two types of chromosomal abnormalities. Specifically, a trisomy is when a person has three of a particular chromosome, instead of the usual two. A monosomy is when they just have one chromosome instead of the usual two.
For example: A trisomy is down syndrome
Explanation:
Answer:
trisomy is when a person has three of the particular chromosome rather than two. Monosomy is when someone has one chromosome rather than the usual two.

SELECT AN ANSWER
-You need to replace cells that are dead or
damaged.
-You want the new cell to have the
capability to live for an infinite amount of
time (avoid death).

What is an example of a physical weathering?
A: a metal tool left outside beginning to rust
B: microscopic organisms producing compounds that break down rock
C: a rock wearing down due to acid rain
D: bits being blown off a rock by heavy winds
Answer:
D) Bits being blown off a rock by heavy winds
Explanation:
All the other answer choices are examples of chemical weathering.
Rusting is chemical weathering.
Compounds that break down rocks is chemical weathering.
Acid rain is chemical weathering.
Wind breaking rocks, however, is physical weathering.
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Answer:
Net force is 100 N
Explanation:
You will use the formula to find the net force/force.
mass = 0.05 kg
acceleration = 2000 m/s^2
F = m × a
F = 0.05 kg × 2000 m/s^2
F = 100 N (Newtons)
Hope this helps, thank you !!

Q: Which image shows the most likely path of a barrel floating down a meandering river?
Answer:
C
Explanation:
A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.'
Image C is the most likely path of a barrel floating down a meandering river.
What is the meandering of a river?A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.' The outer edge of the water moves faster than the inner as it flows around these curves.Meanders form as a result of both deposition and erosion, and they gradually migrate downstream. Because of the decreased friction, the force of the water erodes and undercuts the river bank on the outside of the bend, where the water flow has the most energy.To learn more about : Meanders

photosynthesis uses this form of energy to drive the process
Answer:
i think its the energy of light
Explanation:
Answer:
Light energy
Explanation:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Why does ice cream placed in a plastic cooler melt slower than ice cream placed in a metal pot?
A. because metal is a better insulator than plastic
B. because plastic is a better insulator than metal
C. because metal insulates against more heat
D. because plastic conducts more heat
Answer: B
Explanation:
Because Metal is a poor conductor of heat the inside of a plastic container is insulated and the ice cream will stay cooler longer

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in your own words
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
