The meaning of health hazards

Answers

Answer 1
Answer: Conditions, or objects that are detrimental (bad) for health. For example, asbestos (a type of powder) is a health hazard because if inhaled, it can result in cancer (so this is bad for us).

Which statement is not true of simple machines? A.They can change the amount of work done on an object.
B.They can change the distance over which you apply a force.
C.They can change the direction in which you apply a force.
D.They can change the amount of force you exert.
this is science

Answers

The correct answer is B. They can change the distance over which you apply a force.

Final answer:

The incorrect statement about simple machines is A. They can change the amount of work done on an object. Simple machines do not change the total amount of work; instead, they offer a mechanical advantage by changing the force and distance relationship.

Explanation:

The statement that is not true of simple machines is:

A. They can change the amount of work done on an object.

Simple machines are designed to make work easier by changing the force and distance relationship. However, they do not change the amount of work done on an object because the product of the force applied and the distance over which it is applied (work) remains constant, according to the law of conservation of energy. A simple machine can change the direction of the force, change the amount of force exerted, and change the distance over which the force is applied, which are the benefits of its mechanical advantage.

9. Look closely at the illustration above. a. What process is occurring? b. What is being made? c. How can you tell?

Answers

The answers are:

A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture) 
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C. 

This plant cell has an angular shape, unlike an animal cell, which is rounded. What two plant cell features help give this cell its shape?A) cell wall and DNA
B) cell wall and large vacuole
C) cell membrane and cytoplasm
D) cell membrane and many vacuoles

Answers

Answer:

B) cell wall and large vacuole

Explanation:

A plant cell has tough and rigid cell wall made of cellulose. Presence of cell wall imparts the plant cells a definite angular shape. The angular shape is also the result of presence of large vacuole in the center of the plant cell. The vacuole is filled with water and electrolytes and serve to determine the shape of the plant cell.

You know that there is a difference between plant cells and animals cells. The plant cells have a cytoplasm while the animal cells do not. Therefore the answer must be C.
