Answer:
Cellular respiration occurs in the mitochondria of the cell.
Explanation:
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. They also create glucose, which is a simple sugar with the molecular formula C₆H₁₂O₆. Glucose is the most abundant monosaccharide, a subcategory of carbohydrates.
This all happens in the Mitochondria, or the "Powerhouse of the Cell".
B. By mutating their DNA in response to environmental conditions to gain beneficial traits.
Answer: Acetylcholine. The axons of a motor neuron release the said neurotransmitter which generates an impulse to contract a muscle. It is an organic chemical that functions in the brain and body of organisms.
Answer:
a) circulate through the slug, engulfing bacteria.
Explanation:
Amidst slug cells, Sentinel cells acts as an elementary and competent immune system. These phagocytes goes round the slug body to capture toxic substances and infesting bacteria. It's also known to show the ability to release extracellular DNA traps around the invading/infesting body just ss its eeen in phagocytes of vertebrates and invertebrates.
The option A. Sentinel cells circulate within the slug, engulfing invading bacteria is correct as it also detoxify poisons or toxins, and removing and destroying such from the slug. Its operating mechanism in the cells is regulated by a Toll/Interleukin-1 Receptor domain protein (TirA).
Blue Shift <span>is an occurrence whereby a moving object (galaxy) emits light in such a way that the waves of light actually posses a higher frequency than when emitted</span><span>, the higher frequency of the light results in a shift towards the blue-end of the visible light spectrum. This is a method used in astronomy to determine that a visible object is moving towards the Earth. The only known galaxy exhibiting blue shift is the ANDROMEDA GALAXY. Its light is blue shifted because the galaxy is approaching ours.</span>
