How do the sun and moon affect the tides?
Answer:
The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.

They have jaws, lungs, hair, an amniotic membrane, and a tail but lack bipedal motion.
They share a more recent common evolutionary ancestor with leopards than they do with lizards.

why is global warming dangerous?
Answer:
Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade.
Explanation:
Answer:
The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats. Unless you wanted any of that to happen you need to care about saving the planet however you can.
Explanation:
Which ACTN3 genotype (RR, RX, or XX) would provide these Olympic marathon athletes with an advantage, and why?
Answer:
XX
Explanation:
ACTN3 genotype i.e. XX provides advantage to the Olympic marathon athletes because it strengthens the fiber of the muscles. This gene is also called the gene of speed. This ACTN3 gene has a great influence on the type of fiber that makes body muscles, and they are also linked to strength and endurance so we can conclude that this gene provides benefits to the Olympic marathon athletes by giving strength to the fiber of muscles.
ACTN3 genotype is the gene encoding for the actinin of the skeletal muscle fibres. XX of the ACTN3 genotype will be advantageous for marathon athletes.
What is ACTN3 genotype and XX?ACTN3 genotype is the gene encoding for the protein of the skeletal muscles fibres that are associated with muscular performance. This protein is expressed in the myofibers with a high twitching ability and result in a high-velocity force.
The XX genotype provides strength to the muscles and is the gene coding for the proteins that give speed. They are also responsible for endurance and are beneficial for athletes.
Therefore, XX of the ACTN3 genotype is advantageous for athletes.

Greenhouse gases
are only produced naturally
trap ozone at Earth’s surface
keep Earth cool
absorb heat from the sun
Answer:
absorb heat from the sun
Explanation:
Greenhouse gases are specific type of gases that possess the ability to trap and emit heat/thermal energy in the atmosphere. They are able to do this because of their structure. Examples of greenhouse gases are carbon dioxide (CO2), methane (CH4), chlorofluorocarbon (CFC) etc and are mostly produced via anthropogenic activities.
Greenhouse gases are therefore, produced both artificially (by burning fossil fuels) and naturally and functions to absorb heat from the atmospheric surroundings.
Answer:

As a glacier moves across the land, it pushes soil and rocks in front of it and to the sides of it. What are the hills resulting from this soil called?
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.
Pepsin, trypsin and chymotrypsin are substances that affect reaction rates, those can be defined as
Answer: Enzymes
Explanation:
Enzymes are those proteins which participate in a chemical reaction without being consumed in the reaction. These enzymes work as a catalyst which speed up the rate of the chemical reaction. The enzyme is responsible for converting the substrate into a product. Pepsin is an enzyme present in the stomach it is activated by hydrochloric acid it is a peptic enzyme which converts proteins into peptones, trypsin and chymotrypsin are the enzymes secreted by the pancreas and it is responsible for digestion of proteins.

Answer:
1. A low- pressure weather system can cause a thunderstorm to develop.
2.Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it creates a channel. Once the light is gone the air collapses back in and creates a sound wave that we hear as thunder.
3. One condition that is necessary for a thunderstorm include warm air and moisture.
4. The dangers of a blizzard include getting lost in the snow and freezing to death.
5. In my opinion, a hurricane would be the most difficult storm to face because hurricanes can severely impact your life due to their damage. For example,winds can damage houses, trees, and any other property. Even if your home is safe, flooding aftermath can occur. When homes are destroyed, people may have to rebuild homes and towns.

C. Sensory nerves carry information away from CNS, and motor nerves carry information to the CNS.
D. The PNS controls the sensory nerves and the CNS controls motor nerves.
please help!!!
Answer:
B.
Explanation:
When you touch something the sensory nerves carry it to the brain while your motor nerves tell you to touch it. So being carried to and from. I also got it right on the quiz.
Sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS. Therefore, the correct statement is option B.
What is central nervous system?The central nervous system (CNS) includes the brain and the spinal cord responsible for processing information received from peripheral nervous system (PNS) to generate appropriate responses. The brain is the most complex organ of the CNS, carries various functions, including sensation, perception, movement, etc.
Sensory nerves transmit information from sensory receptors, such as those in the skin, muscles, etc. to central nervous system (CNS) and sensory nerves are activated by various types of stimuli.
Motor nerves transmit signals from the CNS to muscles, and other effectors throughout the body. These signals are responsible for activation of muscle contractions, produce movements, and other responses.
Therefore, sensory and motor nerves both work together to perform physiological functions where sensory nerves carry information to the CNS, and the motor nerves carry information away from the CNS.
