Answer: Need sugar for energy
Explanation: Plants exhibit an autotrophic type of nutrition that is, plants manufacture their own food. They have chlorophyll a green pigment located in the leaves to trap sunlight and convert carbon dioxide and water to glucose and oxygen in a process called photosynthesis. The glucose which is a simple sugar is then transported to other plant tissues where they are needed as source of energy for growth and other metabolic functions.
Animals exhibit a heterotrophic type of nutrition that is, animals cannot manufacture their own food rather they depend on plants and/or other animals for food. Animals use sugars derived from food they eat to obtain energy for all bodily functions.
b. The electron is replaced by electrons generated by the proton gradient.
c. electrons donated directly from plastoquinone at QA.
d. the splitting of water molecules at the manganese center.
e. oxidation of pheophytin. electrons donated from NADPH.
f. electrons transferred from plastocyanin.

Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits
Explanation:
Answer: false
Explanation: Polyester is hydrophobic. For this reason, polyester fabrics don't absorb perspiration, or other fluids, leaving the wearer with a moist, clammy feel. Polyester fibers typically have a low level of wicking. Relative to cotton, polyester is stronger, with a greater ability to stretch
Cannabinoid receptors, located throughout the body, are part of the Endocannabinoid system which is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory.[1]
Cannabinoid receptors are of a class of cell membrane receptors under the G protein-coupled receptor superfamily. As is typical of G protein-coupled receptors, the cannabinoid receptors contain seven transmembrane spanning domains.[5] Cannabinoid receptors are activated by three major groups of ligands: endocannabinoids, produced by the mammillary body; plant cannabinoids (such as Cannabidiol, produced by the cannabis plant); and synthetic cannabinoids (such as HU-210). All of the endocannabinoids and plant cannabinoids are lipophilic, such as fat soluble compounds.
b. a river contaminated with the Giardia protozoan
c. a doorknob contaminated with the cold virus
d. an asymptomatic person infected with HIV
e. a mosquito infected with the malaria protozoan
Answer:
The correct option is: c. a doorknob contaminated with the cold virus
Explanation:
Fomites are the inanimate objects or substances that can get contaminated with the pathogens and are capable of transferring the pathogens to the new hosts.
Sterilization of the possible fomites should be done in order to prevent cross-infection.
Examples of fomites are hair, towels, clothes, door knobs, cups, switches, handrails, remote controls, pens, syringes, bedding, etc.
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only onevariable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.
