What radiation is used in hospitals and how does it cause a problem for staff/workers?

Answers

Radiation is used for X-rays, MRIS, any type of cancer killing. 
Too much of radiation can be a dangerous thing... you could end up dying from a lot of exposure. 
The radiation used is gamma radiation. It causes a problem for staff/workers as it's highly penetrating meaning it can penetrate (go through) almost anything . The staff/workers will have a lot of exposure to this gamma radiation and too much exposure allows the radiation to kill cells, even the useful ones.

Cara and Chuck were looking at pond water through a microscope. They saw this image. Cara wondered what it was. Chuck said it had to be a living thing because it wasA) green.
B) moving.
C) made of cells.
D) round throughout.

Answers

The correct answer is (c) made of cells.

Cell is the basic structural and functional unit of life. The study of cell is called cell biology. Cells can easily be observed under a microscope. As pond water contains many microscopic structures such as bacteria, protozoa, algae and  some small insects they can easily be observed under microscope. The organism that is seen can be unicellular or multicellular            

the answer is made of cells

All of the following are true facts about enzymes EXCEPTA)
all living cells have enzymes.
B)
life would not be possible without enzymes.
C)
enzymes can speed chemical reactions by 100s to millions of times.
D)
there are a few types of enzymes, but they each perform many types of reactions.

Answers

The correct option is D.
Enzymes are biological catalysts which speed up the rate of biochemical reactions in the system of living organisms. There are many types of enzymes and  enzymes are very specific about the type of biochemical reaction they catalyze. Enzymes only catalyze specific chemical reactions; for instance, the enzyme lactase catalyze the breaking down of lactose to glucose. This enzyme will not catalyze any other biochemical reaction except the conversion of lactose to glucose.

Final answer:

The incorrect statement about enzymes is that there are only a few types, each capable of performing many types of reactions. In reality, there are thousands of enzyme types each specifically designed for a particular type of reaction.

Explanation:

The subject of this question is about enzymes, which are proteins functioning as biological catalysts. They speed up chemical reactions and are vital to life. The options A), B), and C) state that all living cells have enzymes, life would not be possible without enzymes, and enzymes can speed up chemical reactions by hundreds to millions of times. These options are all true. But the statement D) that there are a few types of enzymes, each performing many types of reactions, is incorrect. In fact, there are thousands of different types of enzymes and each enzyme usually only catalyzes one type of chemical reaction.

A biologist collects DNA samples from two sisters. The younger sister has blond hair. The older sister has red hair. The sisters have different traits because their DNA contains different —A---order of nucleotides
B---types of sugar molecules
C---sized phosphate groups
D---types of nitrogenous bases
PLZ ANSWER IF U ARE ONLY SMART AT THIS STUFF

Answers

The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

DNA is a double helix composed of two long chains of nucleotides.

In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.

During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.

The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.

In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).
