What ribosomes do? Are they found freely floating in the cytoplasm or they are found attached to another organelle? Or both
Answer:
both
Explanation:
RNA is translated into protein on ribosomes. Protein synthesis is the name of this procedure. Large numbers of ribosomes are present in cells because protein synthesis is crucial to them. In addition to being attached to the endoplasmic reticulum, ribosomes also float freely in the cytoplasm (ER). So they re found in both.
What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.

Imagine a pool ball that bounces off of a bumper and
slowly comes to a halt. Explain what happened at each point in terms of applied
forces and energy transfer
Answer:
The kinetic energy is transferred from the ball to the bumper. The bumper gives the same energy back and the ball eventually stops due to friction of the ground.
Explanation:
Hope this helps y'all <3
When a ball bounces off of a bumper and slowly comes to a halt. The transfer of energy takes place from the ball to the bumper and the ball keeps on bouncing until all the energy is transferred.
What is Energy transfer?Energy transfer takes place when two objects comes in contact due to collision or bouncing. The energy from the moving body is transferred to the body in rest.
In the given situation, elastic potential energy is causing the ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
When a ball is dropped, the gravity pulls ball towards the ground, which slows the ball down so with each bounce the height becomes shorter and shorter, until eventually the ball stops bouncing. On the other hand, the force of the ball hitting the ground puts an equal force back onto the ball which bounces the ball back up.

if a paper clip weighs 1.0 g how many paper clips would be in a paper clip box that weighs 0.5 kg
Answer:
500g
Explanation:
0.5kg=500g
500/1 = 500g
There are 500 paper clips in a paper clip box that weighs 0.5 kg.
What is a Paper clip?A paper clip may be defined as a type of material that is made up of steel or some other metal, but molded plastic is also used for binding up papers.
Weight of one paper clip = 1.0 g.
Number of grams in 0.5 kg = 500 g.
∴ Number of papers clips in 500 g = 500 × 1.0 = 500 paper clips.
Therefore, there are 500 paper clips in a paper clip box that weighs 0.5 kg.

Which of the following statements about microarrays is false?A. Microarrys enable scientists to to determine the activity of thousands of genes at once.B. Microarrys use flurescently labeled cDNA molecules to identify particular genes expressed at a particular time.C. Microarrys use tiny portions of double-stranded RNA fragments from a large number of genes.
Answer: C. Microarrys use tiny portions of double-stranded RNA fragments from a large number of genes.
Explanation:
A DNA microarray) is a solid surface to which a collection of DNA fragments is attached. The surfaces used to fix the DNA are highly variable and can be made of glass, plastic or even silicone. It involves placing thousands of gene sequences in specific locations on a glass slide called a chip. Microarrays basically miniaturizes processes that have been used in molecular genetics laboratories for years. So, a sample containing DNA or RNA is put in contact with the chip, and it allows the detection of DNA or RNA molecules by hybridization or adhesion of the molecules on the slide. The detection of the DNA or RNA adhered is made by different labels or colors that allow them to be detected under the microscope.
Microarrays are usually used to identify genes with differential expression under different conditions. For example, to detect genes that produce certain diseases by comparing expression levels between healthy cells and cells that are developing certain types of diseases. The matching of the complementary bases between the sample and the gene sequences on the chip produces a measurable amount of light. The areas of the chip that produce this light identify the genes that are expressed in that sample.
Then, in summary, the DNA chips are used to analyze the differential expression of genes, and the levels of thousands of genes are monitored simultaneously. And it measures the level of hybridization between the specific probe (probe) and the target molecule (target), indicated by fluorescence and through an image analysis, which indicates the level of gene expression.

please someone help in the metric system, what do kilogram, kilometer, and kilocalorie have in common?
Answer:
1.6 Kilometre is about 1 mile.1 metre is about 3 inches longer than one yard.1 kilogram is a little more than 2 pounds28 grams is about the same as one ounce.Ask me for further explanationAccording to the metric system, the common between kilogram, kilometer, and kilocalorie is as follows:
1 kilogram = 1000 grams (g). 1 kilometer = 1000 meters (m). 1 kilocalories = 1000 calories (cal). What is the Metric system?The metric system may be defined as a type of system that involves the weights and measures in which the meter is the unit of length and the kilogram is the unit of weight.
The metric system significantly represents the standard unit of each parameter like length, weight, temperature, distance, capacity, etc.
The kilogram, kilometer, and kilocalorie have their basic unit which is equal to 1000 times their actual one. This is the common among the all.
Therefore, the commonality between the kilogram, kilometer, and kilocalorie is that all have their basic units equal to 1000 times.

A scientist hypothesizes that a plant with a thin cuticle will not survive as long without water as a plant with thick cuticle. Explain what the scientist could do to test this hypothesis.
Answer:
To make an experiment where plants with thin cuticle are under two different treatments: normal conditions and water stress conditions
Explanation:
An experiment is a scientific procedure that enables to confirm (or reject) a hypothesis. Thus, it is possible to determine the effects of the cuticle on the survival of the plant by subjecting plants with thin cuticle to two experimental conditions (normal and water stress conditions), which can be used to determine if the differences in plant survival are statistically significant to support the hypothesis (e.g., the key role played by the plant cuticle). Moreover, it is important to note that it is imperative to include a control group in order to contrast with the obtained experimental results (e.g., to include plants with thick cuticle in both treatments).
