Explanation: It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
Answer:
Peristalsis is the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wave-like movements that push the contents of the canal forward. (Peristalsis occurs in the esophagus)

An elephant lumbers across African grassland as
dust rises up from each of her steps. She finds a
giant tree and works to pierce its thick bark with
her tusks. She is prying and poking to get at
the water the tree often stores inside. This is no
ordinary tree but a baobab, a tree that looms large
in size and importance for both the animals and
people of Africa The baobab’s astonishing appearance alone proves
it is special. It can grow up to 60 feet high and
30 feet wide, soaring above most other life in the
dry savannah. The baobab has a wide barrel-like
trunk topped with shorter, twisted branches. It
only grows leaves for two short periods, giving the
branches the appearance of gnarled roots for most
of the year. In fact, some African legends say that
a god, angry at the baobab, decided to uproot and
replant it upside down. This remarkable tree survives dry conditions and
is found in many regions of Africa. Its roots spread
out up to a hundred feet away to gather needed
water. The adaptable sponge-like bark contracts in
dry months and expands in wet ones. Baobab trees
serve as a source of water, food, and a safe home
for a variety of animals. In particular, the whitebacked vulture, with a wingspan of about seven
feet, nests high in the baobab’s branches. The great
bird only nests once a year, laying just one egg. The
tall, strong baobab provides the ideal site for several
months of safety for the mother and baby vulture. For centuries, the baobab has also been
essential to the people in various parts of Africa,
many of whom call it the “Tree of Life.” The
baobab’s immense trunk is hollow, creating a
large circular chamber at the center. Baobab
chambers have been used as shelters, prisons,
and animal stables. The tree’s spinach-like
leaves can be eaten, and people use them for
both food and medicine. The fruit provides
a citrus-like refreshment. People strip off the
fibrous bark to make rope, cloth, roofing, and
paper. Unlike most other trees, the baobab can
endure this practice, regenerating its bark and
continuing to grow. Perhaps this is one reason baobabs have such
incredible longevity. Some have even been
known to live for over 2,000 years! These
amazing survivors continue to provide valuable
resources across 32 countries in Africa.
What idea(s) from the passage do the
elephant’s actions in paragraph 1 help
support? Check all that apply.
a-The baobab absorbs water.
b-The baobab provides a safe place to stay.
c- The baobab gives life to animals.
d- The baobab trunk is used for shelter.
e-The baobab lives for thousands of years.
Answer:
A & C
Explanation:
The elephant, by prying at the bark with her tusks is showing that she needs the water from the tree, and that the water is helpful for animals. Hope this helped!

A rocket accelerates from rest to 500 m/s in 10 secconds. What is its acceleration?
Answer:
if you have to Multiply then it's: 5,000 If you have to Divide then it's: 50
Explanation:
500 is the distance then 10 is the speed. I can't remember if you multiply distance and time to get acceleration or if you divided. If you multiply the answer is 5,000. But if you divided then it's 50. I'm really sorry if this wasn't the answer you were looking for. But I really hope this helped.

What causes periodic climate changes over the year?
Answer:
Hiya!!
Many factors, both natural and human, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface. Changes in the greenhouse effect, which affects the amount of heat retained by Earth's atmosphere.
Answer:
Periodic modification of Earth's climate brought about as a result of changed in the atmosphere as well as interactions between the atmosphere and various other geologic, chemical, biological, and geographic factors within the Earth system.
A cymothoid isopod lives inside the mouth of a snapper fish. The isopod servers blood vessels in the fish's tongue, causing the tongue to atrophy and degenerate. The isopod then hooks its pereopods, or legs, to the base of the fish's tongue, essentially replacing the tongue. The isopod stays there for the rest of its life, feeding on blood, mucus, and stray pieces of food from the fish.

Which has more sensory structure your hand or your elbow and why? Which has more sensory structures your mouth or your foot and why?
Please don't write too much just 2-4 sentences
Answer:
Hand and mouth;
Hands have more of the sensory structure of touch, this is because you use your hands more than you would your elbow. Mouths have the sensory structure of taste, as well as the sense of touch, so mouths have more sensory structures than your foot.
Answer:
Your elbow because if you hit it kinda hard it will hurt because your nerves are flaring to the touch. Your mouth because it has more sensory glands and has more stuff touching its sensory glands.

4. A rocket is a spacecraft sent to explore without humans.

Hope this helps.
A satellite is any small object that orbits a larger object. The space shuttle was developed as a reusable means of transporting people and materials between Earth and space. A lander touches down on a planet's surface. A space probe is a spacecraft sent to explore without humans. A rocket uses exhaust to propel itself.
Any small object that orbits a bigger object is a satellite. Satellites can be man-made or natural, such as moons orbiting other planets or man-made objects sent into space to carry out certain functions.
A reusable method of moving people and cargo between Earth and space was established with the space shuttle. It was a spaceship that NASA utilised for a variety of tasks, such as setting up satellites, carrying out research, and maintaining the Hubble Space Telescope.
On the surface of a planet, a lander touches down. It is a spaceship intended to safely touch down on the surface of a celestial body, like a planet, the moon, or an asteroid.
In order to learn more about the surface and surroundings of the body they land on, landers are often fitted with instruments and experiments.
A spaceship launched to explore without humans is called a space probe. Unmanned robotic spacecraft known as probes are launched to collect data in space or undertake scientific examinations of celestial entities.
They have a range of devices and sensors that they may use to gather data and send it back to Earth.
Thus, exhaust is used by a rocket to propel itself. Rockets are autonomous vehicles that move forward by ejecting high-velocity gases from their engines.

okay so i have two questions theres no right or wrong answers just give me ur opinion and why you feel that way pls ..
Opinionated question 1. Many plants like soy bean and corn have been selectively bred. Do you think this is acceptable?? why or why not???
Opinionated question 2. Do you think humans should have selectively bred dogs? Why or why not?
Thanks.
Answer:
1. No, because by selectively breeding the plants you are causing the population to be very similar and could possibly not allow the plants to benefit at all times from environmental factors that could cause them health risks.
2. No, because by not selective breeding dogs we allowed for their to be a larger population of different dogs which allows some to be good at a specific thing and others not to be. This allows variety and genetic diversity allowing us to choose which dog we want/need for different things like work or just to have.
