2. Tania went outside and made two observations of the Moon that were several days apart. Her
observations are shown in the diagram above. The light part of the Moon appeared to get larger over
time. Why did this happen?
The reason why the light part of the moon appeared to get larger over time is because between the first observation and the second observation, the moon moved so that Tania was able to see not of the half that faces the sun.
It should be noted that from the observation that Tania made, the light part of the moon appeared to get larger over time.
The reason for the above want due to rotation but rather because the moon moved so she was able to see not of the half that faces the sun.

Which scenario MOST LIKELY represents genetic drift and why?
A. Scenario 1, because chance events led to a decrease in the number of dark beetles.
B. Scenario 2, because chance events led to a decrease in the number of light beetles.
C. Scenario 1, because the light beetles are most fit for the environment.
D. Scenario 2, because the dark beetles are most fit for the environment.
Answer:
A
Explanation:
The hurricane was by chance and genetic drift is about chance
Scenario 1, because chance events led to a decrease in the number of dark beetles. The correct option is A.
What is genetic drift?Genetic drift is a random process that can result in changes in allele frequency in a population over time.
In Scenario 1, random events reduced the number of dark beetles, implying that the frequency of the dark allele in the population decreased.
Natural selection or other factors that would have favored light beetles over dark beetles did not cause this decrease in frequency.
The dark beetles were affected more than the light beetles due to chance events such as random mortality or reproduction.
This is a classic example of genetic drift, in which random events cause changes in allele frequencies over time in a population.
Thus, the correct option is A.

(Help) Why are the cells produced by meiosis considered gametes?
gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).

Choose 3 activities that you perform regularly and explain the role(s) that each organ system plays in each activity, as well as explain how organ systems work together to perform the chosen activities.
Examples of activities students might choose:
• Arts (drawing/painting, dance or music performance, acting)
• Athletics (exercises/workout routines, sports)
• Food/Culinary-related (cooking, eating different cuisines)
• Other hobbies (video games/TV)
• Other student choices?
Connections with your chosen activities may be:
• Direct – How are your chosen activities directly controlled/performed by different organ systems and processes in the body?
• Analogies – How are your chosen activities similar/analogous to different organ systems and processes in the body?
Answer:
When you breath, your lungs expand filling the blood with oxygen, when you eat, the food breaks down in your stomach causing the nutrients from the food to be absorbed by your body/blood, when you play sports or exercise that newly oxygenated/nutritionized blood is then pumped faster through the body by the heart.

The breaking down of starch into its component sugars would be an example of
A. Catabolism
B. Cell Division
C. Protein Synthesis
Answer:
A. Catabolism
Explanation:
Catabolism is the process by which complex molecules are broken down into simpler molecules, like starch to component sugars or proteins to amino acids. Cell division is the process by which a parent cell will divide into two or more daughter cells, like mitosis or meiosis. Protein synthesis is the process by which proteins are made, this is through transcription and translation.

Adult humans normally produce feces with low water content due to the activities of the large intestine.
What are the functions of large intestine?The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum. Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
The large intestine has 3 primary functions: absorbing water and electrolytes, producing and absorbing vitamins, and forming and propelling feces toward the rectum for elimination.
The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.

These organisms niche in an environment is to break down dead or decaying matter.
Group of answer choices
a. Carnivore
b. Producer
c. Herbivore
d. Detritivore
Answer: Detritivore
Explanation: These are vital organisms that grow by breaking down dead and decaying matter. Some of these are scavengers - macro-organisms that feed on dead or decaying matter, e.g. flies, cockroaches, earthworms. Others are decomposers, generally microscopic bacteria and fungi, that break down wastes. These are also called saprophytes and play an important role in returning nutrients to the soil from dead and decaying matter.

Which of the following statements most correctly explains why the genetic code is referred to as a universal code?
The organization of similar organisms into groups helps scientists understand how living things are related. It
also allows scientists to communicate about all forms of life. Scientists organize the living world using a process
called taxonomy, which is the science of classifying organisms based on shared structures, functions, and
relationships to other organisms. Scientists use a branching system of classification, and over the years, due to
new discoveries, the branching system has changed and grown.
Recently, scientists broadened the branching system of classification. Currently, the broadest group is the
