Answer:
they have 3 layers
Explanation:
endoderm, the ectoderm, and the mesoderm.
C. electron transport and chemiosmosis
Chemiosmosis<span> involves movement of </span>ions<span> across a </span>semipermeable membrane<span>, down their </span>electrochemical gradient<span>. More specifically, it relates to the generation of </span>adenosine triphosphate<span> (ATP) by the movement of </span>hydrogen<span> ions across a </span>membrane<span> during </span>cellular during respiration<span> </span><span>.</span>Hydrogen ions, or protons<span>, will </span>diffuse<span> from an area of high proton concentration to an area of lower proton concentration, and an </span>electrochemical concentration gradient<span> of protons across a membrane can be harnessed to make ATP. This process is related to </span>osmosis<span>, the diffusion of </span>water<span> across a membrane, which is why it is called "chemiosmosis".</span>
Asides from phospholipid (which is made up of two fatty acid tails, and a phosphate-linked head and
glycerol), the plasma membrane also has the following components:
1. Cholesterol (Which together with phospholipids form the
lipid bilayer)
2. Proteins
3. Carbohydrate Groups
Quantitative data uses quantities or numbers.
so C is qualitative (it uses qualities like colors)
B is not referring to data or recording
i think A is the best option
Answer:
Tobacco smoke contains dozens of carcinogens, including nicotine and formaldehyde. Exposure to tobacco smoke is the leading cause of lung cancer. Some chemicals that were previously added to foods, such as certain dyes, are now known to cause cancer.
