After radiation exposure, a cell that cannot divide will most likely stay in which phase?
Answer:
G0 phase
Explanation:
IF the cell doesn't receive a signal to divide, then it will go into a stage called the G0 phase. Most cells are in this stage until they receive a signal to divide, and then continue the cell cycle.

Explanation:
Which statement describes a law based on a tested hypothesis explains how the process occurs describes something about the natural world subject to change as new evidence is discovered
Answer:
based on a tested hypothesis
Explanation:
Laws are generally based on tested hypotheses.
Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that cannot be changed.
Scientific laws are internally consistent, compatible with evidence, and are testable against a wide range of phenomenon. However, they can be reviewed as more evidences emerge that have not been known before.

Compared with mitosis, the process of meiosis results in daughter cells that are-
A. haploid cells with the same number of chromosomes as the parent cells
B. haploid cells with a smaller number of chromosomes than the parent cells
C. diploid cells with a smaller number of chromosomes than the parent cells
D. diploid cells with the same number of chromosomes as the parent cells
Answer:
Explanation:
eAnswer: Haploid cells with a smaller number of chromosomes than the parent cell
Explanation: meiosis results in four daughter cells which are haploids. Haploids have half the number of chromosomes of the diploid parent cell.
Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

Crossing over occurs during meiosis and leads to changes in the chromosomes. What type of chromosomes does crossing over produce?
1. Chromosomes containing DNA from two different parental chromosomes
2. Chromosomes identical in genetic makeup to the parental chromosomes
3. Chromosomes containing more genes with non recombinant chromosomes
4. Chromosomes carrying genes from one parent
Answer:
1.
Explanation:
because the DNA is being mixed up while crossing over
Crossing over occurs during meiosis and leads to chromosomes containing DNA from two different parental chromosomes, hence option 1 is correct.
What is meiosis?New allelic combinations are created in the daughter cells as a result of the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis.
Homologous chromosomes couple along their lengths during meiosis, one from each parent. At locations known as chiasma, the chromosomes overlap.
The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
Therefore, the genetic complement in each daughter cell at the end of meiosis is best described as a haploid set of chromosomes resulting from chromosomal recombination between the parents.

Why were Wegener's ideas about continental drift initially rejected
Answer:
The main reason that Wegener's hypothesis was not accepted was that he suggested no mechanism for moving the continents.
Explanation:
It wasn't until 1928 that a Scottish Geologist, Arthur Holmes, came up with an explanation for why continents move. He believed that heat traps in the Earth caused convection currents. There were areas where fluids trapped beneath Earth's crust heat up, rise, spread laterally, then cool and drop back down. This hypothesis didn't have a wide acceptance either but was revived in the 1940s and 1950s when scientists started to learn more about the seafloor and the magnetic properties of oceanic crust.

Nancy visits a local reservoir where she feeds ducks and other birds. Every time she feeds them she notices that they fight for the best pieces and some do not get any. All living things struggle to get the necessary amount of food, water, and shelter. What is the term for this struggle? * A. overproduction B. natural selection C. variation D. Competition
Answer:
D. Competition
Explanation:
Hope u guys have great day. ✌❤
Competition is defined as a biological interaction between or among the same or different organisms where organisms fight for resources. Competition explains this struggle. So, the correct option is D.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms will always limit the resource available to the other that reduces the quantity.
Competition is defined as a biological interaction between or among the same or different organisms where organisms fight for resources. Competition explains this struggle. Some example of competition is trees in the forest grow tall to compete for sunlight.

Explanation:
You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

What happens to energy that is transmitted through or reflected off a material?
When light is transmitted through or reflected off a material, the light is converted into heat.
What is light?Light is an entity that make things visible to eyes. It is an electromagnetic radiation. It can not be produced or end, it's just converted into one form to another form.
The item may absorb the light wave, in which case its energy is changed to heat. The object might reflect the light wave. Additionally, the object might transmit the light wave. When this happens, things often selectively absorb, reflect, or transmit certain light frequencies.
The light is passed through some objects and do not get passed through some objects. The light that do not pass through an object is reflected back to the same place, but when it is not reflected, it converts into heat.
Therefore, the light is converted into heat when it is not reflected.
