Describe the process of water moving in and out of the cell.
Answers
Answer:
Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

Does Natural Selection affect individuals or populations? EXPLAIN.
Answers
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Place the terms into the correct column that describes the reactions of photosynthesis.
Answers
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
Explanation:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.

Microfilaments are a component of a cell's cytoskeleton and are made of the protein actin. They are important for giving a cell its shape and also aid in _______.
A.) Protein synthesis
B.) Cellular movement
C.) DNA replication
D.) Energy conversion
Answers
Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.
What are Microfilaments?Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.
Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.
Therefore, the correct option is B.

Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This keeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?
Answers
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.
Normal cells VS mutant cellsNormal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.
While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

B. DNA must stay inside the nucleus.
C. Ribosomes are too big to enter the nucleus.
D. DNA is too degenerate to use without mRNA.
Answers
Answer:
A
Explanation:
its not D or C and B might be true but its A okay
Why must an mRNA copy be made for Protein Synthesis because C. Ribosomes are too big to enter the nucleus
Why is mRNA important for protein synthesis?
mRNA is the molecule that includes the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is vital because ribosomes cannot attain the DNA inside our cell nucleus, which is the region within the mobile wherein DNA is housed.
Why is it important to make an mRNA reproduction of a DNA gene earlier than protein synthesis?
So as for cellular to fabricate these proteins, particular genes inside its DNA should first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into completely useful proteins.

Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
these twins look so different even though they have the same parents. Why aren't they identical? In
your answer you should include your knowledge of gametes (sperm and egg), chromosomes, and
variation
Answers
Answer:
Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.
I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

Short term atmospheric conditions give information regarding the weather in an area and Long-term precipitation and temperature data can give an indication of the climate of an area, both statement true.
What are weather and climate conditions?Weather is the collective name for the momentary properties of the lower atmosphere, including precipitation, temperature, humidity, wind speed, direction, and atmospheric pressure. The possibilities are endless: it may be bright, cloudy, rainy, foggy, chilly, hot, windy, stormy, snowy, etc.
Seasons, documented climate cycles, or volcanism are frequently to blame for short-term climate change, which affects shorter timescales.
Long-term climate change affects longer time periods and may be brought on by human activity, variations in the sun's output, or a sluggish recovery from the Flood.
Therefore, weather refers to atmospheric circumstances for a brief period of time, whereas climate refers to long-term, predictable atmospheric conditions.
