C
photosynthesis in the bark
D
closing of stomata in daylight

Answers

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).

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?

Answers

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.

Answers

Answer: A or D

Explanation:

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

Answers

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.
