An adaptation is a way that an animal has changed in its environment that allows the animal to survive.
Adaptations make the species more genetically diverse
Answer: Adaptations helps the organism to have genetic variability.
Explanation:
Adaptations help the organism to survive in the extreme conditions. This is because there is something special in the body of the organism that helps in living the life more smoothly.
In case of any change in the environmental conditions the change in the body of the organism helps in survival. Such as padded feet of polar beer aids in living in such an extreme colder environment.
The polar beers that evolved and adapted in such conditions will survive and rest will not.Adaptation in the body is genetic that aids in physical change.
So, adaptations helps in survival of organisms by genetic variability.
Inside Earth, a(n) ____forms due to the different temperatures of the core
and mantle.
O
A. convection cell
B. equilibrium cell
O
C. conservation cell
O
D. density cell
Answer: A. convection cell.
Explanation: The center of the Earth is known as the core, it is situated deep inside the earth, where melted lava is also found. Because of this, it becomes a very hot center of the Earth. It is also known as the powerhouse of the planet.Most of the raw sources of minerals and metals are found in the core. The melting point is very high over here and the temperature goes about 1,538 degrees Celcius resulting in drops of iron or metal compounds. This geothermal gradient of the planet and the continuous rotation of the Earth thus forms the convection cells and leads to creating a convection current.What occurs during translation?

Moon in apogee orbit, Moon moves a direct line between Sun and Earth; Moon in new moon phase
4.
What causes a partial lunar eclipse?
Only the penumbra of the Earth passes across the Moon creating a circular shadow.
The Earth's umbra fits inside the Moon creating an illuminated ring known as a annular eclipse.
A partial eclipse causes the Moon to turn reddish from the refraction of the Sun's ray through the Earth atmosphere.
The Earth's umbra only cover a part of the Moon causing a circular shadow to pass across it.
The right answer to number four is
The Earth's umbra only cover a part of the Moon causing a circular shadow to pass across it.
A partial lunar eclipse happens when the Earth's umbra part moves across the Moon making a circular shadow across the Moon. An annular lunar eclipse is not possible because the Earth's umbra is always larger than surface of the Moon even if the orbits are in apogee.
For the following:
During a lunar eclipse, the Sun, Earth, and Moon are aligned, with the Earth in the middle.A partial solar eclipse occurs when the Moon only partially covers the Sun.A total solar eclipse occurs when the Moon is in perigee orbit, is moving directly in front of the Sun, and is in new moon phase.A partial lunar eclipse occurs when only part of the Moon passes through the Earth's umbra.What are the functions of eclipse?1. The Sun, Earth and Moon are aligned with the Earth in the middle and the Moon furthest away from the Sun.

Answer:
D. We know more about the Cenozoic era because this the most recent time period in the history of the Earth, and we have more information available to study.
Explanation:
The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in. Because it is the most recent era, the Cenozoic is abundant with lot of evidence of what has happened in it. The fossil records are very rich as the fossils didn't had that much time to totally decompose. The rock layers are much younger, so they contain much more detailed evidence of the plant life, climate, changes in the environment. The oceanic crust is also in abundance, which is not the case with the other eras as the oceanic crust is constantly suducted.
D. We know more about the Cenozoic era because this is the most recent time period in the history of the Earth, and we have more information available to study.
The correct option is D. The Cenozoic era is the most recent era in the geological time scale, spanning from approximately 66 million years ago to the present day. As it is the closest era to our current time, there is a wealth of information available for study. Compared to earlier eras, the Cenozoic era has been extensively documented through various sources, such as geological records, fossil evidence, and climate data.
In the Cenozoic era, there have been significant developments in the diversity and complexity of life forms, including the emergence and evolution of mammals, birds, flowering plants, and other organisms that are more familiar to us today. This increased biological diversity further contributes to the wealth of information we have about the Cenozoic era compared to earlier periods.

What is the gravity force,or weight, of a 40kg child on earth?
Answer:
Gravity force = mass × gravitational field strength (g). The child’s weight is: 40 × 10 = 400 N. (g on Earth = 10 N/kg). The child's mass is 40 kg.
Explanation:
Please mark brainliest and have a great day!
The weight of the child whose mass is 40 Kg on earth is 392 Newtons.
What is Weight ?
Weight is the force exerted by the earth on an object at the surface of the earth. Mathematically -
W = m x g
where -
[m] is the mass of object
[g] is acceleration due to gravity
Given is the mass of a child equivalent to 40 Kg.
We can write -
Mass [m] = 90 kg
Acceleration due to gravity [g] = 9.8 m/s²

Which of the following describes a phenomenon that occurs when we observe plants that wilt?
A. The plant begins absorbing oxygen and releasing carbon dioxide into the atmosphere.
B. The roots begin to rot, causing them to no longer uptake water.
C. The xylem releases all its water.
D. The stomata close, cutting off transpiration and gas exchange.
Stomatal closure is a defense mechanism to prevent further water loss when a plant is wilting. This process cuts off transpiration and gas exchange to conserve water, but also affects photosynthesis.
When we observe plants that wilt, the phenomenon described is one where a plant's ability to uptake water through its roots is not keeping pace with the rate of transpiration. This mismatch leads to a loss of turgor pressure, which is the pressure within the cells that keeps the plant upright and firm. As the turgor pressure drops, the stomata, tiny openings on the leaves, begin to close, which reduces both transpiration and photosynthesis, and the plant appears wilted. So, the correct choice is D. The stomata close, cutting off transpiration and gas exchange. Plants absorb water primarily through root hairs, and it travels up to the leaves through the xylem. Transpiration, the process of water vapor exiting the stomata, is critical for pulling water up the plant. When this process is disrupted, the result is wilting.

Answer:
Based on my opinion, I think that people can misdiagnose themselves with flu.
Explanation:
The flu usually starts with a high fever, followed by pain in the body, head, runny nose and dry cough. Basically these are the symptoms of a common flu. However, a flu considered "normal" can lead to pneumonia, thus requiring hospitalization. If you self-medicate, without know about what kind of disease you have, you can take several risks, including: taking the wrong medicine; take an overdose of the medicine, and thus worsen your condition; If you have an allergy to such a remedy, you may even die if you take it.
It may also happen that you confuse flu symptoms with another, even more striking, illness, as mentioned earlier, pneumonia. And for this reason, you can complicated and then even die about a mistake made by yourself. It is so complicated to self-medicate without a knowloedge about each diseases, lika doctors and nurses have.
