Answer: Option C.
Macroevolution is a change in allele frequencies within a population.
Explanation:
Microevolution is the change in allele frequencies within a population over time. Microevolution is caused by four processes which are natural selection, artificial selection, gene flow and gene drift and these are referred to as fundament forces of evolution.
The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.
- The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
- Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
- The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
- Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.

That’s a false ?? I’m not that sure , but it’s a maybe .
Answer:
A
Explanation:
Coal is majorly used to produces electricity. The coal is ignited and the heat produced used to heat water to steam. The steam is then used to drive turbines with a dynamo effect to produce electricity. Turning off lights when not in use reduces the demand for electricity hence reducing the amount of coal needed to meet this demand.
Other ways to conserve energy is using bulbs with low energy demand - such as LEDs - and improving natural lighting indoors.
There are two types of polymers, which are natural and synthetic. Although natural polymers do not affect the environment, synthetic polymers do.Synthetic polymers are anything that is manufactured or influenced by humans. Due to this, these types of polymers release reactants which are hazardous; both to humans and the environment.Synthetic polymers, which include plastics, rubber, How do polymers effect the environment?adhesives, and Styrofoam cannot be degraded into the environment, causing a buildup of these chemicals all at once, causing a release of any "excess" chemicals into the environment.From there on, polymers create garbage loads, and chemical reactants that effect the environment, and spread around. Therefore effecting anything grown or eaten around it. This could call chemical poisoning to the greenery, animals, and living organisms around it. Not all polymers are bad. In fact humans are made up of polymers. But polymers from sources such as crude oil synthesized into plastics release toxins as they break down. When you burn plastics synthesized from crude oil feedstock, carbon dioxide and dioxins can be released into the air if smoke is not properly <span>What are the bad effects of polymers on your environment?filtered as they are in high quality waste-to-energy incinerators. Also plastics </span>are non biodegradable and so landfills are used to bury the plastic this takes up space and also costs money because there is not enough room for all the <span>waste. Therefore plastics are banned in some areas.
