Which list best describes what should be worn by students in a biology lab where pouring chemicals into beakers is involved?a long-sleeved shirt, safety glasses, protective gloves, and sandals
a long-sleeved shirt, safety glasses, protective gloves, and closed shoes
a lab coat, safety glasses, protective gloves, and sandals
a lab coat, safety glasses, protective gloves, and closed shoes

Answers

Answer 1
Answer:

Answer: Option (d) is the correct answer.

Explanation:

In a laboratory, while performing an experiment it is necessary to follow necessary safety measures so that any misshapen may not result in a serious injury.

Therefore, when we pour chemicals into a beaker then it is advisable that we should be wearing safety glasses so that any spurting won't let the chemical to enter in our eyes. Protective gloves will save our hands from coming directly in contact with the acid.

Whereas a lab-coat and closed shoes will protect our rest of the body from the chemicals.

Thus, we can conclude that a lab coat, safety glasses, protective gloves, and closed shoes is the list of materials to be worn while performing an experiment.

Which lung sound possesses the characteristics of being louder and higher in pitch, with a short silence between inspiration and expiration and with expiration being longer than inspiration?A) BronchovesicularB) VesicularC) BronchialD) Tracheal

Answers

Answer:

C. Bronchial

Explanation:

The different types of lung sounds, also known as breath sounds differ from each other with respect to their location, pitch, relative duration, and intensity.

The bronchial breath sounds are heard just above the clavicle on either side of sternum bone and are characterized by loud amplitude, harsh quality, and high pitch. The bronchial breath sounds are hollow tubular.

The bronchial breath sounds have a short period of silence between the inspiratory and expiratory sounds. The expiratory bronchial sounds last longer than the inspiratory bronchial sounds (I<E).

Wolves are predators of deer. What is most likely to happen to the deer population if the wolf population increased?1)stay the same
2)increase
3)decrease
4)become extinct

Answers

There will be decrease in the population of Deer. So, the correct option is (C).

What is Predation?

Predation is defined as a biological interaction where one organism called the predator kills and eats another organism called the prey. It is one of a family of general feeding behaviors that includes parasitism and micropredation.

Living organisms obtain the energy required for their metabolic activities in their natural environment by eating each other. According to this above information, wolves are predators of deer which means that they eat deer to gain their energy.

If the population of these wolves increases for some reason, obviously they will be less deer. That's why all wolves need to fill their stomachs, they don't starve. Those deer will not go extinct because it is not possible. They may be endangered, which means less dear.

Thus, there will be decrease in the population of Deer. So, the correct option is (C).

Which statement correctly distinguishes photosynthesis and respiration?Photosynthesis occurs in animal cells and not plant cells.

Cell respiration occurs in animal cells and not plant cells.

Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.

Photosynthesis uses light as energy source, and cell respiration uses chemical energy.

Answers

Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy

Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this  process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.

Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.







Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.

The correct statement that distinguishes photosynthesis and respiration is:

Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.

In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.

On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).

This process occurs in both plant and animal cells, specifically in the mitochondria.

Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.

Therefore option d. is the correct answer.

What are the frist 3 stages of the cell cycle called?

Answers

The first three stages of the cell cycle are collectively called the "Interphase". Interphase comprises 3 stages specifically G1, S1 and G2. G1 is called the First Gap Phase, followed by S phase for synthesis and then G2 for the second gap phase. I hope this helps you. 
Interphase proceeds in three stages, G1, S, and G2, preceded by the previous cycle of mitosis and cytokinesis. The cell's nuclear chromosomes are duplicated during S phase.
