A pine tree is between the seedling and adult stages. What would you expect to notice when observing this plant?

-The plant grows more needles, and the stem gets thicker and stronger.
-The plant has a soft stem, and the roots of the plant begin to grow.
-The plant is ready for reproduction, and the embryo produces food.
-The stem of the plant sprouts, and a new plant begins to grow.

Which statement best describes the process of evolution?

b. Environmental conditions limit the number of species on Earth d. The traits of a species can change over time
c. Populations grow when resources are abundant
d. The traits of a species can change over time

Red beryl is one of the rarest minerals in the world. Because it is so rare, red beryl is about 1000 times more valuable than gold. Read the passage that describes how red beryl forms. Use the information to draw an inference about why red beryl has been found in only four places on Earth.


It takes several steps for red beryl to form. First, a volcano with lava rich in topaz rhyolite erupts. Volcanoes with this type of lava have been found only in the United States, Mexico, Russia, and Mongolia. If the lava cools at just the right speed — not too quickly and not too slowly — it will shrink and form large gaps. The gaps fill with hot volcanic gases rich in beryllium, a rare element. Over time, surface water seeps into the cracks and reacts with the gases, forming red beryl crystals.

Science is painful I will give brainily to the correct answer :D

I need help with this

Select an option for each scenario:

If the subject without diabetes eats a high-carb food such as the candy bar or orange smoothie, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.

If the subject without diabetes eats a low-carb food such as cheese or peanuts, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.

If the subject with type 1 diabetes eats a high-carb food such as the candy bar or orange smoothie, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.

If the subject with type 1 diabetes eats a low-carb food such as cheese or peanuts, then the blood glucose levels will (increase/decrease/stay the same) after a three-hour digestion period.

¨When scientists approach a problem to solve, they will often start by gathering information. You and your friends decide to do the same. The park ranger helps out by giving you a map of the park with information about the surrounding areas.¨

1.What information can you get from this map that is relevant to the problem being solved?

2.What further information do you need to gather to solve this problem? What investigations do you think you should conduct in order to test your predictions?

3.Based on the information you have gathered about the areas surrounding the pond, have your predictions about the cause of the algal bloom changed? Write what you now think the main cause is and the reasons for your new predictions.

What happens to matter that is used up during photosynthesis?

It retains its form and mass.
It retains its form but increases in mass.
It changes to a new form of matter with less mass.
It changes to a new form of matter with the same mass.
