Answer:
Chloroplast
Explanation:
This organelle in cells indicates that an organism can harness energy from the sun and other abiotic factors like carbon dioxide to make their own ‘food’. Chroloplasts have chlorophyl piments that contains photosystems centers that harness energy from the sun for photosynthesis. This light energy from the sun is captured and transferred in chemical bonds of manufactured carbohydrates which are stored in the plants. These plants transfer this energy in an ecosystem when they are consumed by higher organisms in the food chain.
Answer:
Variations are caused by mutation. random mating between organisms.
Explanation:
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Answer: The process that happens during primary wastewater treatment is:
A. Insoluble particles are removed by settling.
Explanation: Settling is an operation that removes suspended particles in the water to be treated.
Answer: This phenomena suggests that building an animal body will require a lot of precisely timed steps (building an animal body will involve a lot of steps, precision, and timings).
Explanation:
Scientists have discovered that the lifetimes of mRNAs( Ribonucleic acids) coding for pair-rule regulatory elements in Drosophila embryos may last only a few minutes. This discovery is telling us that if you go into the process of building an animal body, such process will involve a lot of timings and precision.
However, this is a very tedious task as it involves a lot of precision and timings. For you to accomplish such task you must not miss any step, also all the steps must be precisely timed.
Therefore, the discovery insinuates that building an animal body requires a sequence of steps which must be precisely timed.
