Answer:
b: Chromosomes assort independently and crossing-over occurs.
•Crossing-over results in genetic recombination by producing a new mixture of genetic material. Each homologous pair consists of four chromatids, because each chromosome in the pair had replicated before meiosis began. Homologous pairs (tetrads) are still paired together and arrange in the middle of the cell.

Why does water run through gravel quickly?
A.Gravel has a high porosity (lots of holes)
B.Gravel has a low porosity (few holes)
C.Gravel does not have a porosity which makes the water move quickly
Answer: I belive it is A
Explanation:
Gravel is not packet super tight like say dirt is. The small spaces between the tiny chunks of rock and mineral that are present in gravel allow water too smoothly slide in.

what is heat capacity?
Answer:
The heat capacity or thermal capacity of a material is a physical property defined as the quantity of heat to be supplied to a given mass of a material in order to alter the temperature of the unit. Joule per kelvin is the SI unit of heat power. A detailed property is heat power. Heat capacity is defined as the quantity of heat needed to increase the temperature of the material mass by 1 °C.
Explanation:
have a good day :)
Explanation:
Heat capacity,ratio of heat absorbed by a material to the temperature change. it is usually expressed as calories per degree in terms of the actual amount of material being considered,most commonly applied mole ( the molecular weight in gram).The heat capacity in calories per gram is called specific heat.

Can someone please help me on this question
Answer:
homeostatic regulation
Explanation:
This is the is the process that maintains physiological equilibrium that is controlled through the nervous and endocrine systems.
I also got this question right on edge 2021.
Both positive and negative feedback play important roles in the physiology of homeostatic regulation by providing mechanisms to allow the organism to return to homeostasis.
What is a Feedback mechanism?A feedback mechanism may be characterized as the mechanism of the body in order to maintain the levels of hormones in the body to the desired limits. An increase or decrease in the levels of the hormones and enzymes triggers the feedback mechanism.
The process of homeostasis typically involves negative feedback loops that counteract a set of alterations in various properties from their target values. These are known as set points. In contrast to negative feedback loops, positive feedback loops may also amplify their initiating stimuli, in other words, they migrate the system away from its starting state.
Therefore, homeostatic regulations provide mechanisms to allow the organism to return to homeostasis with respect to both positive and negative feedback.

What keeps all of the planets in the solar system from leaving their orbits around
the Sun? *
A: The repulsion of each planet's magnetic field keeps the planets in orbit.
B: The gravitational pull of the Sun keeps the planets from leaving their orbits.
C: The gamma, infrared, and radio waves being emitted from each planet create a path
for it to orbit the Sun.
CD: The gravitational pull of each planet provides just enough force to keep them apart
from one another but still in orbit around the Sun.
Answer:
B: The gravitational pull of the Sun keeps the planets from leaving their orbits.
Explanation:
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

What are chromatids? Group of answer choices nucleus Cells organelles They hold together chromosomes Strands of replicated chromosomes
Answer:
Strands of replicated chromosomes.
Explanation:
Chromatids are strands that have the genetic information in a replicated chromosome. In other words, they are the strands that form the chromosome that will later separate in the anaphase. Chromatids have a short arm and a long arm, telomeres, are nucleotide sequences at the end of the chromatids, and the centromere, which holds the two sister chromatids together.

Homeostasis is the process of maintaining a cell's environment. This
includes the regulation of sodium ion (Na+) concentration within the
cytoplasm. If too much Na+ is inside a cell, how can the concentration be
changed?
A) More Na+ ions will be transported in through membrane protein channels
B) Excess Na+ ions will leave the cell via osmosis
C) More Na+ ions will enter the cell through the plasma membrane
D) Excess Na+ ions will be transported out though membrane protein channels
Homeostasis is the procedure of maintaining a cell's environment: Excess Na+ ions will be exhilarated out through membrane protein channels.
What is the Homeostasis process?
Homeostasis is especially crucial for the survival of organisms. It is often seen as an opposition to differences in the external environment. Similarly, homeostasis is a self-regulating process that controls internal variables required to sustain life.
The body retains homeostasis by controlling a host of variables running from body temperature, blood glucose levels to fluid balance, potassium blood pH, sodium, and calcium ion concentrations.
Therefore, The correct option is 'D'.

Answer:
Heat energy
Explanation:
When the surface water is warm, the storm sucks up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. This heat energy is the fuel for the storm.

How can cloning be used in Science Fiction Texts? Explain your answer with details from stories you have read/watched previously.
Answer:
It really just depends how you plan to use cloning in a Science Fiction text. If you're talking about cloning an animal like Dolly, then you could create a story about a farm with purely identical animals and such. If you're talking about absurd cloning methods such as a copying machine, then you could do whatever you want. It really just varies as to how in depth and realistic you want cloning to be in your story.
A cell has a defect that results in the loss of its ability to regulate the movement of water, food and wastes into and out of the cell. In which of the following cell structures is this defect most likely to be located?
A. Ribosomes
B. Chloroplasts
C. Cell Membrane
D. Endoplasmic reticulum
Answer:
C
Explanation:
The answer is C
If a cell has a defect that results in the loss of its ability to regulate the movement of water, food, and wastes in and out of the cell, the most likely defected structure would be the cell membrane. The correct option would be C.
The cell membrane primarily functions to regulate the movement of substances out of the cell. It is selectively permeable in that only substances that need to be removed from the cell are allowed to exit while those that are needed by the cell are allowed entry. In other words, the cell membrane helps the cell to maintain homeostasis.
