7. A student astronomer went out and took photographs of the Moon that were several days apart.
Images that look like her photographs are shown above. The light part of the Moon appeared to get
smaller over time. Why did this happen?
a
Between the first photograph and the second photograph, the Moon moved farther away
from the sun so less sunlight reached the Moon's surface.
b
Between the first photograph and the second photograph, Earth moved so its shadow was
blocking more of the Moon so the student astronomer was able to see less of it.
с
Between the first photograph and the second photograph, the Moon rotated so that less of
the light-colored rock on the Moon's surface faced Earth.
d
Between the first photograph and the second photograph, the Moon moved so that the
student astronomer was able to see less of the half that faces the sun.

Answers
Answer:yh it is b
Explanation:
A student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.
What is the significance of the moon revolution?The changing appearance of the moon over time is due to its changing position in its orbit around the earth, the light part of the moon appeared to shrink over time as the moon moved in its orbit, causing the illuminated part that faces the earth to diminish and the dark phase to appear.
Hence, a student astronomer went out and took photographs of the moon that were several days apart, and this is because the moon moved so that the student astronomer was able to see less of the half that faces the sun, which is option d.

why do we need new body cells
Answers
Answer:
When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often. But some cells, such as skin cells or blood cells are dividing al the time. When cells become damaged or die the body makes new cells to replace them.

Answers
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

focusing on a single task is the best strategy for change
Explanation:
The career of Jacques Cousteau illustrates that focusing on a single task in life is the best strategy for the change in the social life of an individual as well as in the society. If a person performs many activities at the same time so its focus and concentration divides over the activities which is not more advantageous as compared to that person who focus on the single task until it is completed so focus on the single task in life is necessary for producing big change in life and in the society.
