Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?
Hi, rachellelunaa!!
I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.
I really hope this answers your question!!
The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.
What are the cranial bones?Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).
The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.
Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.
Therefore, preventing damage to skull and brain, we are born with separate cranial bones.

Which adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture?
A
a deep root system
B
loss of leaves during a drought
C
photosynthesis in the bark
D
closing of stomata in daylight
a - a deep root system
The closing of stomata in daylight is an adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture (Option D).
What is an adaptation?An adaptation is a phenotypic feature that allows an organism to survive in particular environmental conditions.
Stomata are structures in plants that allow the interchange of gases required during photosynthesis.The closing of stomata represents an adaptation to arid conditions because it avoids water loss.In conclusion, the closing of stomata in daylight is an adaptation to a dry climate most helps the elephant tree continue to grow by reducing the loss of moisture (Option D).

1. 1. What happens during cell differentiation?
Answer:
Cellular differentiation is the process in which a cell changes from one cell type to another. Usually, the cell changes to a more specialized type. ... Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover.

B. Explain how 2 parents who do NOT have Cystic Fibrosis could have a child with cystic
fibrosis.
Answer:
a.When an organism is heterogeneous for a trait, it expresses only the dominant allele
b. A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier. They are healthy and don't have the disease. But they are a carrier of the disease.

Answer:
C: Converting radiant energy into chemical energy.
Explanation:
Only plants (producers) in a typical ecostystem can convert radiant energy into chemical energy.
Answer:
Converting Radiant energy into Chemical energy.
Explanation:
There are two main purposes for plants. 1. Providing oxygen 2. serving as producers. As we know, plants take in the sunlight from the sun and make glucose with it. This glucose in its form is chemical energy that benefits both the plants, or the consumers that eat them, or some parts of the plant. It does not talk about oxygen or atmosphere except for nitrogen, which they actually get from the ground. Therefore, Converting Radiant energy into Chemical energy would be the right answer.
Which physical property of a medium is defined by how close the particles of the substance are to each other?
Answer:
The question is not complete as the options are not given, here are the options gotten from another website.
A) Crest.
B. trough.
C) density.
D) amplitude
The correct option is C.
Density.
Explanation:
This is because density of a particle is measured or define as the mass or weight of a particle divided by it's volume. This is a physical property which is determined through it's mass and volume, it illustrate how particles are closer or tend to move bearer to each other through it's mass and volume.
For many years, scientists thought that the universe was static—that it had always existed and been the same, and it was neither expanding nor contracting. Then, in the late 1920s, Edwin Hubble recognized that the shift in light from distant objects toward the red end of the spectrum meant that those objects were moving away from Earth. The best explanation for these observations was that the universe was not static but was expanding. More recent observations, such as cosmic background radiation, are also better explained by an expanding universe rather than a static universe. What aspect of scientific methodology best explains the replacement of the static universe theory with the expanding universe theory?
A Science and its methods are always improving. Scientists needed newer, more sensitive instruments to detect the slow expansion of the universe.
B Hubble’s observations were extremely popular with the public, leading to overwhelming support for the new theory.
C The new theory explained Hubble’s observations, and it was tested and supported by additional observations. The theory was accepted because it was the most powerful explanation available for many observations.
D The natural progression of science is that all theories are eventually replaced by new theories until one is established as law
Answer:
C
Explanation:
B has nothing to do with the scientific method. The public does not determine a scientific law. Facts do.
D may be sort of true, but it does not explain Hubble's process. Nor does it explain what Hubble actually did and how he reported it. D is incorrect.
A was never implied (although it is likely true. On the other hand, many great scientific principles are uncovered with very simple apparatus.) A might be 1/2 true.
I think the best answer is C. It is general enough to be accepted. There are two theories mentioned. So C is the best answer.

Your lungs take in air through the mouth and nose. Explain how the lungs function in the human body.
A) They coordinate the movement of the heart.
B) They pass oxygen from the air into the blood.
C) They pump the blood throughout the body.
D) They remove carbon dioxide from the air.
Answer:
Your answer would be "B) They pass oxygen from the air into the blood."
Explanation:
They certainly don't coordinate the movement of the heart, so A isn't an option.
The lungs also don't pump blood through the body, that's the hearts job.
And the lungs do not filter carbon out of the air, which eliminates D.
Therefore your answer is B.
The lungs function in the human body by passing oxygen from the air into the blood.
Gaseous exchange in the lungGaseous exchange happens in the lung of humans. Oxygen is exchanged for carbon dioxide.
A mixture of air is taken through the mouth and the nose into the lung. On getting to the lung, the oxygen in the air dissolves on the surface of the lung and enters the blood by diffusion.
In exchange, carbon dioxide in the blood diffuses in the opposite direction and is breathed out.

A. The amount of the gravitational force quadruples.
B. The amount of the gravitational force doubles.
C. The amount of the gravitational force decreases by one-half.
D. The amount of the gravitational force remains the same.
Answer:
part b is the right answer
Explanation:
The amount of the gravitational force doubles
When the mass of an object doubles; The amount of gravitational force between it and another object whose mass stays the same doubles.
Gravitational forceAccording to Newton's law of universal gravitation;
The gravitational force between two objects is directly proportional to the product of their mass and Inversely proportional to the square of their distance apart.On this note, since the mass of the other object is kept constant; the gravitational force is doubled when the mass of the object is doubled.
