The first organic compound is Carbohydrates. Most organisms use is as a primary fuel or their main energy source. They make up cell structures, and they're also used as stored energy in plants. Second is Lipids. If we have any other energy left over in our bodies, we typically will store that as lipids, which a lot of people think of as fats. It also makes up the cell membrane, and coats the leaves of plants to make them waterproof and also protect them from the elements. Third type are proteins. One use of proteins are chemical messengers or hormones. Proteins are useful for receptors and transport channels in order to help things move in and out of the cell. They also help to control and regulate chemical reactions. Another use is for cell structures, like your hair. the last one is for immunity. The fourth and last is Nucleic Acids. There are two main uses in organisms for nucleic acids. The first one is for protein synthesis. The other use is for our hereditary information or how we pass our traits to our offspring.
Rosa made a chart to summarize the characteristics of two types of social behavior.
Which headings best complete the chart?
X: Herding
Y: Cooperative Hunting
X: Flocking
Y: Migrating
X: Cooperative Hunting
Y: Herding
X: Migrating
Y: Flocking
Answer:
The correct answer is that X is herding and Y is cooperative hunting.
Explanation:
Herding refers to the act of animals that form groups at the time of grazing in the field. It enhances the protection of the individual member of the group by developing confusion in the mind of the predator. Herding can also enhance the occurrences of finding a mate as the animals stick close to each other, thus, there are exhibits a greater chance of reproductive success.
On the other hand, cooperative hunting refers to the act of hunting animals in packs. It is generally followed by animals like wolves and lions. These carnivores corner the prey to separate them from their herds and hunt them. This enhances the chances of effectively catching the prey.
Which action is prevented by the cell membrane?
The plasma membrane is _____ which means it permits the passage of only certain molecules into and out of the cell, and blocks the passage of some substance altogether

Georgia’s Coastal Plains region includes about 60% of the state. Long ago this area was part of the Atlantic Ocean and completely covered by water. A unique wetland feature of the Southeastern Coastal Plain is the Carolina Bay. Carolina Bays are oval shaped wetlands found from Maryland south to Georgia. Some support permanent lakes while others experience more irregular water levels. Carolina Bays range from 6 to 30 feet deep and from several acres to 6,000 acres in size. Due to varying water levels, the vegetation differs dramatically from one Bay to another. Some are characterized by cypress forests, others marsh and some shrub bogs. Georgia is home to more than 1,000 Carolina Bays, covering 250,000 acres.
Carolina Bays along with cypress and gum ponds are important inland wetlands that provide habitat for a wide range of plants and animals. Carolina Bays tend to have some peat development, which is a layer of partially decomposed plant matter. Several Georgia Bays have peat deposits over 14 feet deep, the end product of about 9,000 years of plant decomposition and periodically, these peat deposits catch fire and burn usually about every 25 years. This fire plays an important role in the maintenance of Carolina Bays. How?
A) The fires keep the Carolina Bay habitat from becoming overgrown with vegetation.
B) The fires in the Carolina Bays help to dissipate dangerous chemicals dissolved in the groundwater.
C) The fires in the Carolina Bay areas drive out invasive animal species that out-compete native species.
D) The fires throughout the Carolina Bays help to keep the plant species consistent throughout the states.
Answer:
A) The fires keep the Carolina Bay habitat from becoming overgrown with vegetation.
Explanation:
Peat is an organic material consisting of elements from the decomposition of plants. This material is brown in color (dark or light depending on the type) and is very rich in charcoal. Its nature depends on the environmental conditions present in its formation. It is mainly used in gardening as part of the substrate, but is also beneficial in natural environments as it promotes soil protection, organic matter supply, higher water porosity and higher soil retention. However, it is important that from time to time excess peat be removed from natural environments, otherwise peat can take over an entire space and leave a habitat overgrown. The removal of this excess peat is what explains the advantage of natural fires occurring in the Carolina Bay habitat, the advantage is that fires prevent the Carolina Bay habitat from being overgrown.

Which best defines the relationship between speed and velocity? Speed is velocity with displacement. Velocity is speed with displacement. Speed is based on a specific direction. Velocity is based on distance.
Answer : Velocity is speed with displacement
Explanation :
The speed of an object is defined as the total distance covered divided by total time taken.
The velocity of an object is defined as the total displacement divided by total time taken.
The speed is a scalar quantity because it has only magnitude while the velocity is a vector quantity i.e. having both magnitude and direction.
The relationship between speed and velocity is " velocity is speed with displacement ".
Hence, the correct option is (b).

A. The ice decreases the length of fishing seasons.
B. The melting ice provides more open land for plant growth.
C. The melting ice means less habitat for some marine species.
D. The oil rigs increase temperatures, resulting in species migrations
Answer: C. The melting ice means less habitat for some marine species.
Explanation:
The melting of ice of Artic sea ice will lead to the increase in the water levels which will be suitable for the survival of some of the aquatic species like krills, whales and fishes. But the animals which thrive over the frozen ice of Artic sea like penguines, polar bear will not survive.Hence, the diversity of the region will reduce.
Answer: C. The melting ice means less habitat for some marine species

What is "feminism"? describe how it has evolved in the united states?
Final answer:
Feminism is an ideology that seeks to achieve gender equality and has evolved through several waves in the United States, from the suffrage movement to contemporary feminist activism that addresses a broad spectrum of issues.
Explanation:
What is Feminism?
Feminism is a movement and ideology that advocates for equality between the sexes, aiming to eliminate sexism and promote equal rights in all spheres of life. Originating as féminisme in French, the concept of feminism has significantly evolved over time. It became widespread in the United States throughout the 20th century, aligning with the Women's Movement that fought for suffrage and later expanded to address diverse women's issues.
Evolution of Feminism in the United States
The first wave of feminism was characterized by the women's suffrage movement, with activists like Elizabeth Cady Stanton working towards gaining the right to vote, which was achieved in 1920. The second wave in the 1960s shifted focus to broader issues such as reproductive rights, equal employment, and challenging gender roles. By the 1970s, feminist activism had made inroads into various fields, including the art world, pushing for equality and representation. Despite differences, by the 1980s, advances such as improved employment opportunities and access to health and education were significant feminist achievements.
Modern feminism encompasses a wide range of perspectives, recognizing the diverse experiences of women, including but not limited to women of color, working-class women, disabled women, and those from different sexual orientations and religious backgrounds. This inclusive approach, as argued by feminists like Barbara Smith, seeks to free all women from the constraints of sexism and societal expectations.

Which combination provides an example of protein complementation?
Peanut butter sandwich combination provides an example of protein complementation. Whenever legumes like beans, lentils, or peanuts are combined with grains like corn, wheat, or rice, a complete protein is introduced. Peanut butter on whole wheat is a snack that is pretty high in calories and provides a huge amount of all the essential amino acids and lots of healthy fats to boot
Protein complementation occurs when incomplete proteins from different plant sources are combined to provide all essential amino acids, like rice and beans combining grains and legumes to create a complete protein profile.
Explanation:Protein complementation is the process of combining incomplete proteins from various plant sources to provide all the essential amino acids that the body cannot produce on its own. A classic example of protein complementation is the combination of grains and legumes, such as rice and beans. This combination is effective because grains typically lack the amino acid lysine, while legumes lack methionine and cysteine. By consuming both throughout the day, even if not at the same meal, the body receives a complete amino acid profile similar to that found in complete proteins from animal sources.
