Civil Rights Movement and Women's Suffrage Movement are 2 examples of how ordinary citizens created significant social change.

Civil Rights Movement in the United States: The Civil Rights Movement of the 1950s and 1960s saw ordinary citizens, such as Rosa Parks, Martin Luther King Jr., and countless others, playing crucial roles in challenging racial segregation and discrimination. Through peaceful protests, civil disobedience, and grassroots activism, they brought attention to the injustices faced by African Americans and fought for equal rights, leading to significant changes in legislation and societal attitudes.

Women's Suffrage Movement: The women's suffrage movement fought for women's right to vote and brought about significant social change. Ordinary citizens, including suffragettes like Susan B. Anthony and Elizabeth Cady Stanton, organized rallies, protests, and campaigns to advocate for women's suffrage. Their persistent efforts, spanning several decades, eventually led to the passage of the 19th Amendment in 1920, granting women the right to vote in the United States.

Based on the pedigree shown and the pattern of inheritance of lactose intolerance, Persons 11 and 12 were lactose intolerant while Persons 8, 9, and 10 were not because they are hom0zygous for the recessive allele for lactose intolerance while Persons 8, 9, and 10 are heterozygous for the recessive allele for the trait for lactose intolerance.

Lactose intolerance results from a person's inability to produce the enzyme lactase that breaks down the sugar lactose found in milk. Many adults experience lactose intolerance as they age and rely less on milk and dairy products as sources of nutrition. There is another rare form of lactose intolerance that affects infants from birth. A mutated version of the LCT gene that codes for the production of lactase exist as a recessive allele.

A lack of the body's lactase enzyme is the typical cause of lactose intolerance.

Abdominal cramps, bloating, and diarrhea is examples of symptoms.

Avoiding dairy products, using lactose-free goods, or using lactase tablets are the mainstays of treatment.

The investigation of the Hudson River is an example of scientific inquiry because it develops testable questions such as this; How might a zebra mussel invasion affect  the Hudson River ecosystem?

All the other elements of scientific inquiry were applied.

Explanation:

Developing and using models: Scientists developed ways to check for changes in the river using the data available to them.

• Planning and carrying out investigations: Several scientific institutes have planned and carried out investigations to determine reasons for the return of the Zebra mussels.

• Analyzing and interpreting data: Graphs are plotted to evaluate to draw a relationship between the zooplankton and the Zebra mussels.

• Using mathematics and computer technology : Mathematical measurements were done to analyze the sizes of the Zebra mussels.

• Constructing explanations : Explanations were proposed as to why the Zebra mussels were not eating up them. It made sense to them that more Zebra mussels would result in more Zooplanktons

• Engaging in argument from evidence : They could argue from the evidence that blue cobras were eating up the Zebra mussels

• Obtaining, evaluating, and communicating information: After scientists have obtained their information, they endeavor to communicate them by publishing them in scientific papers and journals.

A pelican is a water bird that has evolved to be able to dive into the water to catch fish. Pelicans are known for their large bills, which they use to scoop up fish from the water. A pelican with excellent eyesight has the ability to spot fish in water from above, diving down to catch them.

Pelicans have a unique set of adaptations that allow them to spot fish from above the water's surface. Pelicans have large eyes that are well-suited to detecting movement, which is essential for spotting fish in the water. They also have the ability to adjust the lenses in their eyes to focus on objects both in the air and underwater

.Their keen eyesight and keen sense of hearing make them excellent hunters, and they are known for their ability to spot fish even in murky water.

Once a pelican spots a fish, it will fold its wings and dive headfirst into the water to catch it. Pelicans can hold their breath for up to a minute while they dive underwater to catch fish, and they can swallow their prey whole. Pelicans are fascinating birds that have a unique set of adaptations that allow them to thrive in their aquatic habitat.

The statement is true.

Explanation:

As every single living organism, the mice also have their own unique requirements as to how much food they need to produce enough energy in order to stay healthy. Because the mice are small, warm-blooded, highly active, and have very fast metabolisms, they need a lot of food for their size.

If one mouse needs four square meters of grass to stay healthy, so if we want to find out how much grass is needed for more mice we just need to multiply the number of mice by the amount of grass needed for one mice. In this case, we have 50 mice:

4 x 50 = 200

We got 200 square meters of grass, meaning that that would be the amount/area of grass that will be enough to support the population of 50 mice.

A rock lies in a river bed in a warm and wet climate, and the factor that would speed up its weathering is the flow of the water, which slows down considerably. That is option c.

In general, the rock weathering that is seen in the river beds is due to the water flowing, which leads to increased erosion and gives the slower moving water more time to dissolve minerals.

Hence, a rock lies in a river bed in a warm and wet climate, and the factor that would speed up its weathering is the flow of the water, which slows down considerably. That is option c.

All mutations will result in a change in phenotype, regardless of whether the DNA sequence, amino acid sequence, or mRNA sequence altered.

An organism's hereditary genes determine its phenotype, or physical characteristics and behaviours. Genes are specific DNA sections that encode for the creation of proteins and specify unique features.

New phenotypes are rarely created. Mutations may be inherited and hence transmitted from one person to another. If a mutation produces a novel phenotype that makes an organism more suited to a certain environment, it can swiftly change the attributes of the individuals in a species.

The given statement " Algae indeed produce energy-rich carbon compounds through photosynthesis". is True because  Photosynthesis is a vital process that occurs in the chloroplasts of algae cells.

During photosynthesis, algae capture light energy using pigments like chlorophyll and convert it into chemical energy. They utilize this energy to break down water molecules, releasing oxygen as a byproduct, and incorporating carbon dioxide from the surrounding environment. Through a series of enzymatic reactions, algae synthesize glucose, a high-energy carbon compound.

Glucose serves as a primary source of energy for algae, enabling them to carry out essential metabolic processes and sustain their growth. Additionally, algae can convert excess glucose into other energy-rich carbon compounds, such as lipids and starches, which serve as energy storage molecules. These compounds can be used during periods of limited sunlight or nutrient availability.

Overall, algae's ability to generate energy-rich carbon compounds through photosynthesis makes them an important component of aquatic ecosystems and potential sources for renewable energy production and biofuel development.

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.
