The following guidelines should be included in most safety policies because they apply to practically all laboratories. They go on emergency preparedness, appropriate signs, safety gear, how to use lab equipment properly, and fundamental common sense standards.
Make careful to read any safety and fire alarm signs, and in the event of an accident or emergency, heed the directions.Make sure you are completely informed of the evacuation protocols for your building or facility.Make sure you are familiar with the location and proper use of all of the safety supplies in your lab, including eye wash stations, fire extinguishers, first aid kits, and safety showers.Be aware of the emergency phone numbers to call for assistance.Lab spaces with lasers, radioisotopes, and other biohazards need to be adequately labeled with warning signs.When working in the lab, avoid eating, drinking, and chewing gum.Never use laboratory glassware as a container for food or drink.Make sure to inspect your glassware for chips and cracks before each usage. Glassware that is broken should be reported to your lab manager so it can be disposed of properly.Never utilize lab equipment that you have not been given permission or been taught to use by your supervisor.Inform a technician as soon as possible if an instrument or piece of equipment malfunctions while in use or isn't functioning properly. Never attempt to fix a piece of equipment by yourself.

Here is an image of the mitochondria. Mitochondria numbers can differ between cell types based on the function of the cell. Which of these cells would contain the highest number of mitochondria?
Answer:
Muscle cells
Explanation:
Muscle cell have highest number of mitochondria. Thus, option C is correct.
What is mitochondria?
Mitochondria are the power house of the cell, membrane-bound organelles present in the cytoplasm of both plant and animal cell.
It produces adenosine triphosphate (ATP) by breaking down of nutrients. Cellular respiration also occur in mitochondria.
Structurally it comprises three parts such as an outer membrane, an inner membrane, and matrix part which is a gel like structure.
The outer membrane separated by the intermembrane space from the inner membrane and it is composed of proteins and phospholipid layers
The outer membrane has a large number of special proteins called as porins.
It is also involved in regulation of the metabolic activity, promotion of cell growth, multiplication, detoxifying ammonia, apoptosis, make various hormones like testosterone and oestrogen, cellular differentiation, cell signalling, cell senescence, cell cycle control.

Which of the following describes the relationship between photosynthesis and cellular respiration?
A.Only animals carry out cellular respiration, only plants carry out photosynthesis
B.Photosynthesis releases energy from glucose and cellular respiration stores energy as glucose
C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide.
D.Photosynthesis requires oxygen and cellular respiration releases oxygen
Answer:
C.C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide
Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide. Hence, option C is correct.
What is cellular respiration?The process through which organisms use oxygen to break down food molecules in order to get chemical energy for cellular processes is known as cellular respiration. The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration. It takes place in mitochondria and cytoplasm.
Cellular respiration serves the straightforward objective of giving cells the energy they require to function. Food would be completely useless if living beings couldn't obtain the energy they required from it.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen). During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.

If 5x+4y=58 and 3x + 7y = 67 find the value of ( x + y )
Explanation:
5x + 4y = 58 ....1
3x + 7y = 67 ....2
....1 × 3 both sides of the equation
15x + 12y = 174 ....3
....2 × 5 both sides of the equation
15x + 35y = 335 ....4
.....4 - ......3 both sides of the equation
35y - 12y = 335 - 174
23y = 161
y = 161/23

After transcription, the new mRNA strand travels to the cytoplasm and over to the ___________ where the genetic code will be translated into amino acids.
nucleus
cell membrane
ribosomes
golgi bodies
After transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
During gene transcription, a specific fragment of DNA called gene is used to produce a complementary messenger RNA (mRNA) sequence in the cell nucleus.
Subsequently, this mRNA travels to the cytoplasm where it is used as a template to synthesize a polypeptide chain in the ribosomes by a process called translation.
Ribosomes are protein factories that read the genetic code in the mRNA sequence (i.e., the codons of the mRNA) to translate it into the correct order of amino acids of the protein.
In conclusion, after transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
