help me out bro!!! !! ! !

Answer 2
Examples of lab safety rules:
- wearing protective and proper clothing (eg. goggles, gloves, close-toed shoes)
-locating emergency equipment (eg. eyewash station, fire extinguisher, fire blanket)
- not eating or drinking liquids
- handling chemicals properly and following lab procedures
- dispose waste properly and clean up area when finished.
-do not consume any chemicals or substances
- be attentive
There’s a lot more but these are the most common ones.


—————-
These rules are put in place for the learning environment because it ensures the safety of all persons in the lab and prevents any accidents from happening such as injuries and dangers. They also prevent dangers such as cross contamination and explosions from occurring.

A class without lab safety rules would be extremely dangerous and even deadly. People would get injured and many hazardous risks would come up. (like cross contamination, explosions, mentioned above). Injuries like blindness, burns, and cuts can occur. Just imagine a class of 2nd graders with no teacher around. that’s kind of like a lab without safety rules :)

hope that helps!

The World Health Organization (WHO) note that essential nutrients are crucial in supporting a person’s reproduction, good health, and growth. The WHO divide these essential nutrients into two categories: micronutrients and macronutrients.

Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals. Although the body only needs small amounts of them, a deficiency can cause ill health.

Macronutrients are nutrients that a person needs in larger amounts. Macronutrients include water, protein, carbohydrates, and fats.

what are the steps of photosynthesis

Answers

Explanation:

Step 1-Light Dependent

CO2 and H2O enter the leaf

Step 2- Light Dependent

Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2

Step 3- Light Dependent

The electrons move down to enzymes

Step 4-Light Dependent

Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-Light independent

The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Step 6-Light independent

The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.

Although both rely on other living organisms to survive, parasites feed on the host organism.

Although both are living organisms, viruses break down dead plants and animals that other organisms use.

Although both are living organisms, parasites depend on the cells of living things to reproduce.

Answers

Answer:

The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.

Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.

What are parasites?

A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.

Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.

They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.

A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.

The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.

Thus, the correct option is B.

Why are Sunlight and nutrient levels asexual

Answers

Answer:Sexual reproduction allows them to produce fit offspring that can survive under stressed environmental condition

Explanation:Reproducing sexually and asexually allows fungi to adjust as per the environmental condition.  

When the conditions are favorable, they reproduce asexually and increase their number but when the condition are not favorable and environmental selective pressure occur then they undergo genetic variation through sexual reproduction to produce a stable and fit offspring that could survive under stressed condition with limited resources.

Asexual reproduction Since there are plenty of resources, the plant will want to reproduce quickly and colonize the area

c. mutation of a factor critical for degradation of proteins in the lysosome

d. mutation of a factor important for protein folding in the ER

The conditions that would activate the unfolded protein response are:

Synthesis of many extra secreted proteins.Mutation of a factor critical for degradation of proteins in the lysosome.Mutation of a factor important for protein folding in the ER.

What do you mean by unfolded protein response?

The unfolded protein response may be defined as a cellular stress response related to the endoplasmic reticulum stress. It is a mechanism through which the accumulation of misfolded protein is induced.

Unfolded protein response gats are activated when there is any mutation or alteration that takes place in the ER, and sometimes lysosomes. Because these are both organelles that mediate the protein trafficking throughout the cell.

Therefore, the conditions that would activate the unfolded protein response are statements (b), (c), and (d).

when a newly formed cell enters into interphase and begins conducting metabolic functions it's is. •G0 phase •G1phase •G2 phase •S phase

Answers

Answer:

Gap 1 (G1)

- This is the phase in which the cell undergoes normal growth and cell function synthesizing high amounts of proteins.

- The cell increases in size and volume as more cell organelles are produced.

- The cell can only move to the next phase, S after synthesizing enough ribosomes.

- As the phase is almost done, the mitochondria of the cell fuse into a network of mitochondria for effective energy production for cell processes.

- If the cell can not divide again, it enters the G0.
