What are the safety measures that should be taken in laboratory?There are several safety measures that should be taken while performing an experiment in lab such as avoid drink and food while working in laboratory and wear PPE kit to keep yourself safe.
Never work lonely in the lab because this condition will turn into danger situation as suppose a person works lonely and due to reaction of some chemical the person become unconsious than there is no one to help him.
Always wear gloves, PPE kit, proper shoes, lab coat of full sleeves with safety goggles. All these things will helps to keep a person safe in lab while experiment.

Explanation:
The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into chromosomes. Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.
The "code" for physical traits is contained in a molecule is called DNA (genetic code).

After photosynthesis, energy that the coral can use is stored in
molecules of?
Answers:
O2
CO2
H2O
C6H12O6
Answer:
Energy is stored in glucose molecules C6H12O6
Explanation:
Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of photosynthesis. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.
These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.
Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).
Eg. for aerobic respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
as cell size increases the surface area to volume ratio
Answer:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

READING TOOL Make Connections Fill in the concept map to show the
organization of a chloroplast. Then below, answer the questions to describe how the
different parts are related to each other.
Chloroplast
Answer:
Chloroplast -----membranes----------internal
---------external
----- Tylacoids-------------Grana
----- Stroma
You will find the complete concept map in the attached files
Explanation:
The chloroplasts are limited by two membranes, the internal and the external membranes. Both of them are separated by the intermembrane space.
In the interior of the organelle, thylakoids are composing the third system of membranes. In the interior of thylakoids, there is an additional compartment named thylakoid space. This membrane system forms piles, known as grana. Different grana structures connect to each other by a longer thylakoid membrane. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.
To fill in the diagram you will need to show the composition of the chloroplast. Therefore, you should show the internal and external membranes, the thylakoids, the grana, and the stroma.
We can arrive at this answer as follows:
Chloroplasts are organelles present in plant cells, they are very important in the photosynthetic process.Chloroplasts have two membranes, an internal and an external one, which limits the entry and exit of substances.Inside the chloroplasts are the thylakoids, which are formed by structures called grana, which form numerous piles, which resemble towers.The unoccupied space within the chloroplast is filled with a fluid called the stroma.In the figure below you can see how this diagram can be filled.

What is the purpose of protein synthesis?
Answer:
Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.
Explanation:
Proteins are one of the most important biomolecules essential for the survival of organisms owing to the myriad of functions that they play in the physiological system.
Proteins that are ingested are easily degraded to amino acids or peptides by the action of HCl in stomach and the digestive enzymes present in the gastrointestinal tract. Thus, proteins have to be synthesized in the body to meet the body's needs for various functions.
Some of the functions of proteins include:
1. Enzymes are majorly proteinaceous in nature and are required for crucial functions, including cell division and DNA synthesis.
2. Motor proteins help in movement and also provide cytoskeletal structure to the body.
3. They are required for the functioning of the immune system.
4. Proteins are required for cell signaling pathways.

Sterility is an important condition to be maintained in fermenter. true or false?
Answer:
I'm pretty sure it's true.

It's true because, in the fermentation of mashes by bacteria or similar organisms, it is necessary after each fermentation has been completed and the fermented mash removed, to sterilize the fermenter vessel to prevent contamination during the next fermentation.
During the months of July, August, and September, when the squirrels are more active we would expect the artic squirrels:
A) To produce more O2 when compared to other months.
B) To have a higher output of CO2.
C) To produce less water.
D) Increase in the output of glucose.
Answer:
B) To have a higher output of CO2.
Explanation:
We would expect the artic squirrels to produce a higher output of CO₂. As with most heterotrophs, the by-product of their respiratory activities is the formation of carbon dioxide gas.
They use oxygen gas to break down glucose. The process releases energy for their life activities. The waste product is usually carbon dioxide which enters back into the ecosystem as a waste.
