Answer:
The fundamental functions of the cytoskeleton are involved in providing mechanical strength and integrity, enabling the movement of cells and facilitating the intracellular transport of supramolecular structures, vesicles and even organelles.
Explanation:
In addition to the creation of an elastic environment within the cell interior, the cytoskeleton also plays important mechanical roles in linking the plasma membrane of the cell, as well as interior membranes such as the endoplasmic reticulum, to the rest of the cell, in limiting the diffusive motions of intracellular polymers that are larger than the network mesh size, and possibly in controlling the permeation of water and small solutes through the cytoskeleton.
A car travels 300 km in 6 hours. What's the average speed of the car? O 50 km/h O 65 km/h O 45 km/h O 75 km/h
Answer:
50 km/h
Explanation:
The average speed of the car is essentially the same thing as the unit rate.
Here a car goes 300 km for every 6 hours. To find the unit rate, we must find how many kilometers it goes per hour.
To do so, we can divide 300 by 6 to get a total of 50km/h.
Producers, such as those that make the foods that are shown below, make glucose during the process of photosynthesis.
A produce stand of vegetables such as carrots and peppers.
Where in the cell is the glucose produced?
in mitochondria
in chloroplasts
in cytoplasm
in water
Producers produce glucose in the chloroplast
What are Chloroplasts?The chloroplast is a small, elliptic shape, and membrane-bound organelle found in the cells of most green plants.
The chloroplast contains green substances known as chlorophyll. The chlorophyll is responsible for absorbing radiant energy from the sun for the process of photosynthesis.
Both the light-dependent and light-independent reactions take place in the chloroplast.
Thus, the production of glucose which is a light-independent reaction takes place in the chloroplast.

Answer:
C. A-respiration, B-photosynthesis
Explanation:
This is your answer because...
C02 is Carbon Dioxide and H20 is water, and Carbon Dioxide comes out when the animal is breathing (respiratory process) and H20 comes out as urine.H2O + 02 + C6 + H12 + 06 IS things that comes out of a PLANT while it's performing Photosynthesis.H20 is water 02 is OxygenI don't know what the other 3 are, but they HAVE to be glucose.Thanks!

The organelle which controls cellular activity is the.
the Nucleus
Explanation:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
For a heterozygote, production of sufficient quantities of the functional protein by the ______ allele compensates for the production of a non-functional protein by the ______ allele.
For a heterozygote, the production of the protein by the DOMINANT allele compensates for the production of a non-functional protein by the RECESSIVE allele. It is classical genetics.
Alleles and dominanceAn allele is a gene variant, diploid individuals inherit two different alleles for a given gene locus.
A homo-zygous individual has the same alleles, whereas a heterozygous individual has two different alleles for a given gene locus.
Dominance occurs when the dominant allele completely masks the expression of the recessive allele.

12. Scientists have observed that the same gene may produce several different mRNA molecules. How could the researcher's model show this variety of mRNA molecules? Identify the stage that introduces this variety.
Answer:
The stage of introns being removed then exons splicing together can create a variety of tRNA molecules. It's like recycling
mRNA is the messenger RNA associated with the transfer of information and is also associated with protein synthesis. In the given scenario, the stages of introns are removed then exon splicing together can create tRNA variety.
What are introns and exons?Introns and exons are the sequences of nucleotides in the genes.
Exons are coding regions of DNA sequences corresponding to protein, while introns are the RNA or DNA found between the exons.
Scientists have observed that the same gene may produce several different mRNA molecules stages of introns are removed then exon splicing together can create tRNA variety to show the variety of mRNA molecules.
Thus, it is the stage that introduces the mRNA molecule variety.
