The statement is - False.
The vinegaroon has became very similar in appearance to the scorpions, by having similar body, similar proportions to certain species, having a whip tail. The whip tail though is not a mimic for the scorpion's pincher claws, but instead, it is a mimic of the scorpion's stinger. This adaptation of the vinegaroon has the purpose to fend of the predators by making them think that it is actually a scorpion and that they will get a nasty poisonous sting. This type of adaptations by mimicking certain traits of more dangerous species can be found in lot of animals from all shapes and sizes.
The answer is C, since antibiotics will not effect viruses, only bacterial infections.
Cell membranes are not solid structures.
Answer:
A) the concentration of calcium ions in the sarcoplasm of a resting muscle
Explanation:
Sarcoplasmic reticulum is a system of the membranous sac that is present around each myofibril and is filled with calcium ions. When muscles are in the resting stage, calcium ions are stored in the sarcoplasmic reticulum.
As the muscle action potential triggers change in voltage-gated calcium ion channels of the sarcoplasmic reticulum, the channels are opened to release the calcium ions in the sarcoplasm. Increased calcium ion levels in sarcoplasm make the muscle fibers to contract.
Removal of acetylcholine from the synaptic cleft ends the production of muscle action potential and calcium ions are moved back from the sarcoplasmic reticulum.
Hence, lower levels of calcium ions are maintained in sarcoplasm when the muscles are in the resting stage.
Answer:
c. environmental factors such as soil pH
Explanation:
Hydrangea plants do exhibit or take on different forms of colors in reaction to environmental factors most especially, the soil pH.
Generally, Hydrangea plants will produce blue flowers if the soil pH level is below 6, while it would produce pink flowers if the pH of the soil is alkaline in nature (pH value is above 7).
The production of Hydrangea plants on the large flower garden, which produces blue flowers and pink flowers, can simply be explained to be as a result of the sensitivity to soil pH. This results in the change of the color of the flower pigment.
