Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.
Answer:
ATP synthase would be unable to produce ATP
Explanation:
ATP synthase depends on the proton gradient in the intermembrane space to enable it to produce ATP. As a consequence of this, the toxin will make it inactive. Oxidative phosphorylation is now inhibited in this case, as opposed to substrate-level phosphorylation.
Pyruvate is a product of glycolysis, and it will not be affected by a toxin. NADH is very important in the establishing of a proton gradient, so it is expected that it would be unable to be oxidized due to the toxin. Protons produced in the conversion of NADH to NAD+ actually establish the proton gradient. If the gradient is absent, NADH is then not likely to be oxidized.
Answer:
A. simple
Explanation:
Asexual reproduction is mainly used by bacteria or small organisms that are too simple to have created a mechanism for sexual reproduction. The advantage of sexual reproduction is the recombination--why do you think you're not an exact copy of your parent? That's because they didn't have you via asexual reproduction.
Why not B: This is the opposite.
Why not C: This isn't necessarily a requisite condition; many bacteria do not live underwater.
Why not D: This is certainly wrong. Bacteria are not extinct, and not looking to be so anytime soon.
