<span>A mass balance will be necessary to weigh the sodium bicarbonate and a 100ml beaker should be used to contain the solution. For safety, one should wear gloves while handling the sodium bicarbonate and wear goggles in case of splashing. Lab coats and closed shoes must also be worn. 
</span>
Lab apparatus:

- Analytical balance with 0.1 g precision (at least)
- Spatule
- Burette (0.1 mL precision) plus erlenmeyer or a graduated volumetric flask.
- Magnetic agitator


Safety precautions:
- Use gloves of the proper material
- Use safety googles
- Wear lab coat that fits you
<span>- Know where the safety equipment is located</span>

<span>The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing.

LDLs contain _______. LDLs contain _______. steroid hormones cholesterol protein cholesterol and protein cholesterol, protein an
Bezzdna [24]

The correct option is (c) LDL consists of cholesterol and protein.

One of the five main categories of lipoproteins, low-density lipoprotein (LDL), transports cholesterol throughout the body to the areas where it is required for cell repair and deposits it inside the artery walls. They need to be bound to proteins in order to pass through the hydrophilic blood.

The hydrophobic core of the LDL particle is made up of fatty acid esters of cholesterol, while the outer membrane is made up of unesterified cholesterol. The membrane contains a single copy of the hydrophobic apo-B protein, which facilitates the binding of LDL particles to particular cell-surface receptors.

Hence,  LDL consists of cholesterol and protein.
