Why does the moon appear to shine its own light?
--
A. The moon glows from inside its interior.
B. The moon reflects light from Earth.
C. The moon's atmosphere reflects solar radiation.
D. The moon's surface reflects sunlight.
The answer is D. The moon’s surface reflects sunlight.
The moon appear to shine its own light because the moon's surface reflects sunlight which is in option D as moon does not emit its own light like a star. Instead, it appears to shine because it reflects sunlight.
The intensity of the moon's reflected light can vary depending on factors such as the moon's position in its orbit and the angle at which sunlight hits its surface. This is why the moon appears to change in brightness throughout its lunar cycle, which we observe as the different phases of the moon. It's important to note that the moon's atmosphere is extremely thin compared to Earth's atmosphere, and it does not have the ability to scatter or reflect sunlight in the same way Earth's atmosphere does.

Scientists believe the first giraffes on Earth had shorter legs and a shorter neck than giraffes today. What can you conclude about these first giraffes?
Answer: Survival of the fittest
Explanation: There where not many trees in the plains and with so many Giraffes roaming around with little predators, food was hard to come by. As the lower branches started thinning out, only the taller giraffes could reach the higher branches. When there was no food left, the shorter Giraffes started to die off, leaving only the taller giraffes. This is known as Survival of the Fittest because only Giraffes with the taller gene where able to survove. The shorter gene is extinct now becasue they no longer had food to live off of.

5 characteristics of seaweeds
1. Seaweeds, also known as macroalgae, comprise a diverse group of organisms representing various growth forms.
2. Seaweed comes in 3 colors green, brown, and red ( but colors within these groups vary)
3. seaweeds lack the complex reproductive structure found in sea grass and land plants
4. Most seaweed attaches to hard surfaces such as rocks, shells or other algae, using a specialized basal structure called a holdfast; however, a few seaweed species survive over mud or sandy bottoms.
5. Seaweed is autotrophic, which means it produces its own food; using sunlight, macroalgae convert carbon dioxide and water into oxygen and sugar (photosynthesis).
I hope this helps you.
Seaweeds are multicellular organisms that can be green, red, or brown depending on their photosynthetic pigments. They lack true tissues or organs found in land plants and instead have leaf-like blades, stalks, and structures called holdfasts for attachment. Seaweeds are capable of photosynthesis and can be found in diverse habitats.
Explanation:Seaweeds, also known as algae, carry distinct traits that differentiate them from terrestrial plants. Here are five characteristics:
Multicellular Structure: Seaweeds are multicellular as implied in the instance of brown algae (Phaeophyta).Colouration: Their color can be either green, red, or brown, determined by their photosynthetic pigments.Lack of True Tissues or Organs: Unlike land plants, seaweeds do not have true tissues or organs such as leaves, stems, or roots. They have leaf-like blades, stalks, and structures called holdfasts for attachment.Photosynthetic: Seaweeds have multiple photosynthetic pigments (chlorophyll a, chlorophyll c, B-carotene, and fucoxanthine), which enable them to perform photosynthesis.Diverse Habitat: Seaweeds thrive in a variety of habitats including seawater, brackish water, and even snow patches.Learn more about the Characteristics of Seaweeds here:https://brainly.com/question/33442998

Which of the following processes is decreased when many trees are removed from an area?
Answer:
Option (C)
Explanation:
When many trees are removed from any area, the area becomes dry and gets adversely affected. Due to the lesser amount of trees, the area will evaporate more due to its dry and increasing temperature, as a result of which there will be more precipitation. This precipitation will lead to more amount of surface runoff over the area. So the transpiration will simultaneously decrease as the plants will not be able to absorb water by its roots, that regulates the overall temperature of the plant and protects it from dying.
Thus, the transpiration process is directly proportional to the number of plants and trees in any area.
Thus, the correct answer is option (C).

How do adult stem cells differ from embryonic stem cells?
A. Adult stem cells have high healing potential, and embryonic stem cells have low healing potential.
B. Adult stem cells can only be used by adults, and embryonic stem cells can only be used by babies.
C. Adult stem cells have unipotency, and embryonic stem cells have pluripotency.
D. Adult stem cells have totipotency, and embryonic stem cells have multipotency.
Answer:
C
Explanation:
Adult stem cells can only differentiate to form a single type of cell.
Embryonic stem cell are pluripotent as they can differentiate into any cell types except extra embryonic membranes like placenta.
Only zygotic stem cells are totipotent
Adult stem cells differ from embryonic stem cells as Adult stem cells have unipotency, and embryonic stem cells have pluripotency.
Difference between Unipotency and Pluripotency:Unipotency: A unipotent cell is that one stem cell that has the capacity to differentiate into one cell type only.
Pluripotency: pluripotent cell that has the potential to differentiate into any cell of the three germ layers i.e endoderm ( stomach lining, gastrointestinal tract, the lungs etc), mesoderm (muscle, bone, blood, urogenital etc), or ectoderm (epidermal tissues and nervous system etc), but not into cells of extra-embryonic tissues like the placenta.
Adult Stem Cells are unipotent that is they can develop only one type of cell but Embryonic Stem Cells are pluripotent, Hence, can develop into any cell type.

According to the information, the probability of the baby that will have brown eyes is found to be 75%.
What is the reference to having brown eyes?The reference to having brown eyes is determined by the fact that Eye color is directly related to the amount of melanin in the front layers of the iris.
People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment. A particular region on chromosome 15 plays a major role in eye color.
According to the context of this question, brown eyes (B) are dominant over blue eyes (b). Due to this, the genotype of the father is Bb while the genotype of the mother is bb. When they are crossed, they produce offspring with the genotypes Bb, Bb, Bb, and bb. This means that 75% of the offspring possess brown eyes.

The wind stirs up ___ currents.
A. Cold-water
B. Warm-water
C. Deep
D. Surface
Answer:
the answer is Surface
Explanation:
Wind creates surface currents by dragging a layer of water when it passes over the water’s surface. This differs from deep ocean currents which are mainly driven by temperature and salinity differences.
Explanation:Surface currents are oceanic currents that occur at or near the surface of the ocean, and they are primarily driven by the wind. These currents are responsible for moving large amounts of water horizontally across the ocean's surface. Wind interacts with the surface of the ocean, creating friction and causing the water to move in the same direction as the wind.
When the wind blows across the surface of the ocean, it imparts its energy to the water, generating these surface currents. The direction and strength of surface currents depend on factors such as wind speed, wind duration, and the geography of the ocean. These currents can have a significant impact on various aspects of the marine environment, including climate, marine life, and navigation.
So, in the sentence "The wind stirs up surface currents," the word "surface" indicates that the wind's action primarily affects the currents near the surface of the ocean.

B. individuals are randomly exposed to a dangerous virus
C. Human subjects are given an unnecessary medical treatment.
D. healthy people are infected with a deadly pathogen
Answer:
I would say the best answer for this question would be A.
Explanation:
I chose this answer because factually, it does check out. Say, for example there is a clinical trial for a drug to treat a specific disease.
I can rule out B because obviously these doctors would not purposely infect the volunteer with this disease just to take a shot at curing them.
I ruled out C because if we were using this trial drug on a completely healthy person... how would we know that the drug can help/cure the disease in mind if the person never had the disease in the first place. C is simply absurd.
And finally, D is much like B and so I can rule it out as well for the same reason.
