Why are there craters on the surface of the moon?(1 point)
Craters formed when acidic water dissolved the surface of the moon.
Craters developed from deep waterspouts in oceans on the moon.
Craters were created when sinkholes formed after rainstorms on the moon.
Craters resulted when meteoroids crashed into the surface of the moon.
Answer:
Craters resulted when meteoroids crashed into the surface of the moon.
Explanation:
Craters resulted when meteoroids crashed into the surface of the moon. The correct option is D.
What are carters?On many solid planets and moons, craters are the most common surface features.
Craters cover both Mercury and the Moon. Numerous circular holes cover this area of the Moon. Each of these craters was formed when an asteroid or comet collided with the Moon's surface.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite impact, volcanic activity, or an explosion. Impact craters are craters formed by a meteorite colliding with the Earth.
Scientists can study a planet's history using impact craters even when the records are buried beneath the surface.
Buried material is ejected during impact, while outward pressure pushes the rock at the crater's edge upward, forming a rim.
Thus, the correct option is D.

How are energy in information used to keep an organisms body organized
Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Explanation: I hope this helps! NOT MY WORK!
Energy is required for the cells to carry out their metabolic functions. Moreover, information (genetic information) is also fundamental to synthesize and regulate biomolecules required for the cells to carry out their functions.
All cells need energy to carry out their metabolic functions. i.e., to live, grow, and reproduce. Adenosine triphosphate (ATP) is the energy coin of the cell because this molecule provides releasable energy in the bonds between phosphate groups.For example, the energy released by the hydrolysis of ATP is used to synthesize biomolecules, endocytosis, exocytosis, cell motility, cell contraction, etc.The information stored in the sequence of the Deoxyribonucleic acid (DNA) molecule is used to synthesize structural and enzymatic proteins (as well as other cellular components) which are required to carry out cellular functions.Moreover, the information stored in DNA is also required to regulate the expression of genes involved in protein synthesis.In conclusion, energy and information (genetic information) are both fundamental to carry out cellular functions.

B. ¼ acre of trees
C. 2 house plants
D. 8 bathtubs of algae
Photosynthesizing material take up 2 house plants for a single human’s oxygen needed. The correct option is C
What is photosynthesis?
Photosynthesis can be defined as the process used by plants and other organisms to convert light energy into chemical energy that through cellular respiration can later be released to fuel the organism's activities. During photosynthesis in green plants light energy is captured and used to convert water, carbon dioxide and minerals into oxygen and energy rich organic compounds.
Therefore during photosynthesizing requirements needed include Sunlight, water and oxygen where two processes occur one light dependent and another which is light independent.

Jorge is studying a pond ecosystem in his neighborhood. The pond is home to a variety of plant and animal species, as well as a stop for birds that migrate through the region.
One summer, heavy rains wash an unusual amount of fertilizer into the pond. Jorge observes the algae population growing rapidly, and quickly algae cover the pond's surface. Several weeks later, many fish and other animals die in the pond. However, within two years, the algae population has returned to its previous size, as have the populations of all the ecosystem members.
Jorge's observations provide the strongest evidence for which of the following conclusions about the pond?
A. The pond ecosystem has very high biodiversity that protects it from invasive species.
B. The pond ecosystem is resilient to changes in many abiotic and biotic factors.
C. The pond ecosystem can withstand only certain levels of algal growth.
D. The pond ecosystem may change over time, but its species will continue living there indefinitely.
Answer:
I think that the answer is C.
Explanation:
If the levels of algae were too high then it would be the reason as to why the fish died. When the algae went back to normal,the fish were able to live there again.

Identify the following observation as qualitative or quantitative
The solution turned blue in color
Hey there! I'm happy to help!
Quantitative data are data that have to with quantities (numbers).
For example, how many inches tall is the plant, what is the pH level of this fluid, what is the temperature of the meat, etc.
Qualitative data are data that can be described or that have a specific quality (qualitative).
For example, are the flowers yellow or green, is the fluid bubbling, does the meat smell burnt, etc.
We see that a solution turning blue doesn't have to do with numbers, so it is not quantitative. It is qualitative because it has to do with the quality (in this case, color) of the solution and not a numerical statistic.

Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.
