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.

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.

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.

Answers

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.

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.

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.
