Answer:
Explanation:
Gram-negative bacteria are more resistant to lysozyme and antibiotics than Gram-positive bacteria, because they have a largely thick impermeable cell wall (peptidoglycan), an outer lipid membrane that causes reaching of antibiotics to bacteria harder.
Gram positive bacteria have thin lipid peptidoglycan cell walls.
Answer:
Metabolism is the sum total of all the chemical reactions that occur inside the cells.
a) Catabolic pathway: release energy
b) Anabolic pathway: consume energy
c) Anabolic pathway: build up larger molecule
d) Catabolic pathway: break down molecules
e) Uphill: Anabolic
f) Photosynthesis: Anabolic
g) Cellular respiration: catabolic
Explanation:
All the chemical reactions that occur inside the cells are collectively termed as metabolism. There are two types of metabolic reactions. The reactions that break down the large molecules into the smaller ones and release the energy stored in the chemical bonds of the larger molecules are the catabolic reactions. Cellular respiration breaks down glucose into CO2 and H2O to release the energy stored in it. It is an example of the catabolic pathway.
The reactions that synthesize the larger molecules from the simpler substances are anabolic reactions. These are the endothermic reactions and therefore, are also called "uphill" reactions. An example includes photosynthesis that builds glucose from simpler substances like CO2 and H2O.
Answer:
B) a DNA base substitution in gametes during meiosis
Explanation:
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.
Answer:
D
Explanation:
The neural pathway regulates the action reflex. At times sensory neurons synapse occur in the spinal cord rather than the brain, this allows for a quicker reflex action. Synapses in the spinal cord activate spinal motor neurons without delay, which is likely the case if the signals go to the brain, the brain doe however receive the sensory input during the reflex action.
