HELPP!! Which of the following best defines a lunar phase?
a) the portion of the lit part of the moon as seen from earth
b) the change in the literal shape of the moon
c) the change in the orbit of the moon about the earth
d) the different sides of the moon as seen from earth
Answer: A, the portion of the lit part of the moon as seen from earth
Explanation: The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month (about 29.53 days) as the Moon's orbital positions around Earth and Earth around the Sun shift.

16. The students decide to investigate how the mass of each marble affects its kinetic
energy. The students will roll each marble down the first hill on the track. They will
then compare the results for the kinetic energy of both the ceramic marble and the
steel marble.
Which figure best compares the kinetic energy of each marble when the marbles
roll down the hill on the track?
The ceramic marble has half the mass of the steel marble, the kinetic energy increases with increasing mass, hence the correct option is B.
What is kinetic energy?The form of energy that an object has as a result of its motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
The energy an object has as a result of motion is known as kinetic energy. A force must be applied to an object in order to accelerate it.
Due to the fact that kinetic energy is related to the square of the speed, doubling the speed results in a four-fold increase in kinetic energy. The momentum does double with a speed increase, as we will discuss in the following lesson.
Therefore, the ceramic marble has half the mass of the steel marble, the kinetic energy increases with increasing mass.

15. Explain how the speed of a stream affects the suspended load.
Answer:
As a stream flows faster, it can carry larger and larger particles.
Explanation:
Unlike dissolved load, the size of the particle that can be carried as suspended load is determined by the velocity of the stream. As a stream flows faster, it can carry larger and larger particles. The larger the size particle that can be carried by a stream, the greater the stream's competence.

1. Cross a red-flowered snapdragon with a white flowered one. Then perform
another cross with the offspring of the first cross. List genotypic and
phenotypic ratios for each cross.
The genotypic ratio from the crossing of a red-flowered snapdragon with a white flowered and advancing it to F2 one would be 1 R1R1 : 2 R1R2 : 1 R2R2 and the phenotypic ratio would be 1 red : 2 pink : 1 white
Monohybrid crossingThe red flower snapdragon is homzygous for the R1 allele while the white flower one is homzygous for the R2 allele. The R1 allele has incomplete dominance over the R2 allele.

Predict what would happen if the muscles that control structures in the larynx became paralyzed
Answer:
When the nerves of these muscles become weak (paretic) or paralyzed, the muscles relax, and the cartilages tend to collapse inwards resulting in laryngeal paralysis.The intrinsic muscles of the larynx function to move the vocal cartilages and control tension. They are innervated by the vagus nerve
Invasive species, deforestation, and eutrophication are all types of. Question 1 options:
Natural (nature-made) environmental changes
Man-made environmental changes
Both nature and man-made
Neither nature nor man-made
Answer:
B. Man-made environmental changes
Explanation:
Invasive species become what they are because of human interference. People bring animals into new habitats in which it's predators do not live, therefore, that animal can freely feed and overpopulate without anything to keep it under control.
Deforestation is also caused by human interference. We cut down trees for logging, paper, building etc.
Lastly, eutrophication. Eutrophication can be caused by natural occurences, but can also be caused by human actions. Because we are looking for a category to fit all of the things listed, it can be classified as a man-made environmental change. Eutrophication is predominantly caused by human actions due to their dependence on using nitrate and phosphate fertilizers.

The lymphoid tissues located behind the nasal cavity are called.
Answer:
Adenoids!
Explanation:
The adenoids are a mass of soft tissue behind the nasal cavity. Like lymph nodes, adenoids are part of the immune system and are made of the same type of tissue (lymphoid tissue). White blood cells circulate through the adenoids and other lymphoid tissue, reacting to foreign invaders in the body.
The lymphoid tissues located behind the nasal cavity are called adenoids.
What are adenoids?The adenoids are part of the lymphatic system, which is responsible for helping the body fight off infections and diseases. The adenoids are a type of lymphoid tissue that helps to trap and destroy bacteria and viruses that enter the body through the nose and mouth.
They are most prominent in children, but tend to shrink and become less active as a person gets older. Sometimes throughout childhood, adenoids expand, and the larger size may create issues. This condition is termed as enlarged adenoids. An enlarged adenoid may cause snoring, mouth breathing, persistent congestion, nasal drainage, ear problems, sinusitis, and “nasal” voice quality.

In what way is a decomposing log in a forest a microhabitat?
Answer:
A microhabitat is a small or localized ecosystem within a larger ecosystem that is sustained and managed by a variety of small populations of plants and animals.
A rotting or decomposing wood is an example of a microhabitat because it provides food, shelter, and opportunities for various plants and species to interact and form an ecosystem. Interactions between biotic and abiotic variables are also present. As stated in the question, there are numerous other features present in this little ecosystem.

In ecological succession, large herbivores would most likely come first when forming an established ecosystem.
What is ecological succession?Ecological succession is the series of processes that alter the species structure of an ecological community over time.
Ecological succession can either be primary or secondary depending on whether there was an initial life form or not.
However, producers like plants, algae tend to grow first in both cases. Hence, herbivores that will consume them are the most likely come first when forming an established ecosystem.
