What differences can you see in nucleus when you compare a dividing and non dividing cell
Answers
Answer:
The nucleus of a dividing cell is dense and spherical. It is comparatively larger in size during synthetic phase of cell cycle. Nuclear envelop also remain absent in many stages of nuclear division.
Explanation:
If a cell does not go through the Sphase of the cell cycle before mitosis, what might be wrong with the daughter cells?
Answers
Answer:
Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.
Explanation:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.
-----------------------------------------------
As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.
Many regulator molecules act during the different stages of the mitosis process to make it possible.
There are too many factors interacting, activating, and deactivating to pass from one stage to another.
Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.
When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.
Once that stage is over, that cyclin concentration decreases, and the following one increases.
But if any step was not correctly performed, the cell can not pass to the following one.
During the S stage of the interphase occurs the DNI replication process.
At this point, also occurs the synthesis of histones and other associated proteins.
This is the only stage where the DNI molecule is replicated.
S phase cyclins are in charge of regulating the stage of DNA replication.
If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.
The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.

Answers
The image is not given in the question, so the appropriate image is attached below:
Answer:
goblet cells
Explanation:
Goblet cells are the mucin-secreting glands found within epithelia. Their shape and size look like a goblet, hence named goblet cells, and contain narrow bases and wide apex.
The structure highlighted in goblet cells scattered within epithelia. Goblet cells function for producing mucin, create a protective mucus layer and immunoregulation.
Hence, the correct answer is "goblet cells".
Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?
Answers
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

When pouring food coloring into warm water and cold water, we can see that the
molecules in warm water move faster and spread the food coloring more quickly.
(Conduction Lab Experiment)
true
false
Answers
Answer:
true!!
Explanation:
the faster molecules move, the warmer the object is. think of how much energy you feel when you touch hot water and you whip your hand back, thats similar to how the molecules are movin, all that heat is energy built up in them and theyre moving around all crazy haha. Then think of putting ice in the freezer, all the molecules are kinda frozen in place, all squished together, because they dont have enough energy to move around. so, when the hot molecules with all that energy are moving around, the food coloring is able to get all over in the water. Kind of like if youre on a road trip the faster you drive the faster you'll get places. if you drive super slow, then it'll take forever to get there. so true, when food coloring is dropped into faster hotter molecules, it will spread faster. :)
Water is a liquid substance that can act as a solvent for solute components.
It is true that when pouring food coloring into warm water and cold water, we can see that the molecules in warm water move faster and spread the food coloring more quickly.
The energy in the water molecules of warm/hot water is very high due to the effect of heat so when food coloring is poured, the water molecules move at a fast rate causing the food coloring to spread at a fast rate across the water molecules.The energy in the water molecules of cold water is very low so when food coloring is poured, it spreads at a slower rate.Therefore, it is true that when pouring food coloring into warm water and cold water, we can see that the molecules in warm water move faster and spread the food coloring more quickly.

The answer you are looking for is C
Natural selection is a process by which the organisms adjust to the variation in the environmental conditions so they can endure and thrive in the altered conditions.
The correct answer is:
Option C. Directional selection
This can be explained as:
Directional selection is a negative form of natural selection in which the inhabitants of one species is favoured over another.The species with better trait characteristics will be favoured over the organism with less preferred attributes.The allele recurrence in directional assortment shifts over time.Therefore, toads with better traits (head size) are favoured over snakes with smaller mouth sizes.

The total volume of plant cells is often significantly greater than the total volume in animal cells. The most reasonable explanation for this observation is that
A) animal cells are spherical, whereas plant cells are elongated.
B) plant cells are capable of having a much higher surface-to-volume ratio than animal cells.
C) plant cells have a much more highly convoluted (folded) plasma membrane than animal cells.
D) plant cells contain a large vacuole that occupies much of the volume of the cell.
Answers
Answer:
D
Explanation:
In plant cells, the vacuoles are much larger than in animal cells. When a plant cell has stopped growing, there is usually one very large vacuole. Sometimes that vacuole can take up more than half of the cell's volume. The vacuole holds large amounts of water or food.

True value = 10.4 grams
Measured values = 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.
Solution:
To a very reasonable extent, the values measured given are accurate and precise.
Accuracy is the nearness of the measured value to the true value. We can see that the measured value would have a mean of 10.36grams which is very close to the true value on approximation.
Precision is the ability to repeat a given set of values from a measurement. The measured values are quite precise.

Why do some dominant traits have two different types of alleles?
Answers
Answer:
you inherit 2 alleles for each genes. one comes from your biological mom and the other comes from you biological father. if the alleles are identical like when both your parents have brown eyes and that it will cause you to have brown eye color. some alleles are dominant while the rest are recessive. the dominant trait is more stronger than recessive trait. It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth. Additionally, one allele may be dominant for one trait but not others.
