Answer:

C) amino acids

Explanation:

Amino acids were found in the "goo" in the beaker of the Miller-Urey experiment. Therefore, option (C) is correct.

The Miller-Urey experiment was a landmark experiment conducted in 1952 by Stanley Miller and Harold Urey to investigate the origin of life on Earth. The experiment aimed to simulate the conditions of the early Earth and test whether organic molecules, the building blocks of life, could be formed spontaneously from inorganic compounds.

The experiment produced a variety of organic compounds, including amino acids, which are the building blocks of proteins. The results of the Miller-Urey experiment provided evidence that the building blocks of life could have formed spontaneously on the early Earth.

Answer:

Salivary amylase becomes inactive in stomach. Carbohydrate digestion halts until the bolus enters small intestine.

Explanation:

Salivary amylase is present in saliva and breaks down starch in food thus it helps in carbohydrate digestion. The optimum pH for its working is 6.8. As the bolus enters the stomach, pH drops drastically. Gastric juice has pH around 3. Salivary amylase is not able to function in such a low pH and becomes inactive in stomach. As a result, carbohydrate digestion halts in stomach. Gastric juice has its own amylase but it does not digest the starch much.

As the bolus enters the small intestine, the acidic pH is restored to neutral value. Carbohydrate digestion restarts with the help of pancreatic amylase.

Answer:

Because Primary producers like plants are capable of making their own energy from the sun.

Explanation:

Producers make up the bottom of a pyramid. There are many organisms that feed on these producers and use their energy in their own biological processes. These organisms are higher in the pyramid.

Autotrophs are on the bottom of the energy pyramid; Because Primary producers like plants are capable of making their own energy from the sun.

The sun's energy is converted into biomass by autotrophs, the producers in a food web.

Each of the trophic level results in a drop in biomass. The Lower trophic levels always have more biomass than higher trophic levels.

Autotrophs are able to produce their food through photosynthesis; which means they provide food for all other creatures.

The Producers make up the bottom of a pyramid. There are lots of organisms that feed on these producers; use their energy in their own biological processes. These organisms are higher in the pyramid.

Answer:

There are 15 ways to select 2 bracelets.

There are 10 ways to select 2 pieces of jewelry that are not bracelets.

How many ways can Lauren select 4 pieces of jewelry, of which exactly 2 are bracelets?

150

hopes this helps :)

Explanation:

The question relates to the mathematical field of combinatory, particularly combinations. To find the total ways Lauren can choose her jewelry, we use the formula '(n choose 2) * (m choose 2)', where n is the number of bracelets and m is the number of other jewelry items.

The subject of this question appears to be related to combinatorics, specifically, combination. If we suppose that there are 'n' bracelets and 'm' pieces of jewelry that aren't bracelets, Lauren has 'n choose 2' ways to select the bracelets and 'm choose 2' ways to select the other pieces of jewelry. Therefore, the total number of ways in which Lauren can choose her jewelry is the product of the two, i.e., '(n choose 2) × (m choose 2)'.

For example, if Lauren has 3 bracelets and 4 other types of jewelry to choose from, she can select the bracelets in '3 choose 2' = 3 ways, and the other pieces of jewelry in '4 choose 2' = 6 ways. Thus, she has a total of 3×6 = 18 possible ways to choose 2 bracelets and 2 other pieces of jewelry.

Answer:

The bacterial DNA gets degraded at step 3 of the viral lytic cycle.

Explanation:

Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.

The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.

After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.

Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.

Answer & explanation:

B cells or B lymphocytes are produced and divided initially in the yolk sac (structure that stores the calf, a substance responsible for the nutrition of an embryo), then in the liver and later in the bone marrow, where they remain in the form of lymphoid progenitor cells until their maturation .

B cells are responsible for ensuring humoral immunity, characterized by the immune response through the production of antibodies, in order to fight invading cells such as infections by viruses or bacteria.

The stimulation of b cells to divide and mature is provided by T helper cells.

B cells participate in humoral immunity, this is characterized by the production and release of antibodies in order to destroy the antigens for which they were created.

The antigens that induce the activation of B cells can be protein, polysaccharides, lipids, etc, according to what type of antigen they require the participation of T helper cells.

Therefore, we can conclude that the stimulation of b cells to divide and mature is provided by T helper cells.

Answer:

Primary Succession

Explanation:

Because no  organisms previously lived on it. Parking lots can be considered

like rocks, which also undergo primary succession. Overtime soil   will be blown onto the parking lot and if not maintained plants

will begin to grow thus starting new life.

Primary succession will occur if parking lot is abandoned for 1000 years.

The process of establishing plant and animal communities in a place that was previously devoid of life, like barren rock or a recently formed island, is known as primary succession.

Lichens and mosses would first colonize the bare pavement in the abandoned parking lot as the first stage of primary succession, which would then be followed by the emergence of grasses, shrubs, and eventually trees.

A more diverse and complex ecosystem would eventually develop as a result of the plant community's ability to sustain and attract a wide range of species over time, including insects, birds, and mammals.

Depending on a variety of environmental circumstances, the total process of primary succession may take hundreds or even thousands of years.

Thus, the answer is primary succession.

Final answer:

The skin lesion described is probably not melanoma due to its regular borders and uniform pigmentation. It is more likely to be a dermatofibroma due to its benign characteristics. The correct answer is: D) Dermatofibroma

Explanation:

The lesion described in the question is a medium brown circular lesion with regular borders, evenly pigmented, and approximately 7 mm in diameter. According to the ABCDs of skin cancer, concerning characteristics include asymmetry, irregular borders, varied colors, and a diameter greater than 6 mm. Additionally, evolving shape and elevation are signs to watch for. The lesion here does not fit these criteria well, thereby making melanoma (option A) less likely. A dermatofibroma often presents as a firm, benign skin lesion with a smooth or slightly irregular border, varying in color from brown to pinkish, and they can sometimes be mistaken for moles. Dermatofibroma is a more appropriate diagnosis given the described characteristics.

Explanation:

Beneficial mutations are more likely to become common in a population through natural selection, as they enhance survival and reproductive success. These mutations can lead to advantageous traits becoming widespread and potentially fixed within a population's gene pool over time.

Beneficial mutations are more likely to become common in a population through natural selection. Mutations are changes to an organism's DNA and can introduce new genotypic and phenotypic variance. While some mutations may be detrimental or neutral, it is the advantageous mutations that play a crucial role in the process of evolution. Beneficial mutations help organisms survive, reproduce, and better adapt to their environment, thereby increasing the likelihood of being passed on to future generations.

For example, in a population of mice living in a woodland environment, a mutation that causes fur color to closely match the forest floor can lead to a form of stabilizing selection, where mice with this coloration are less likely to be predated and more likely to reproduce. Over time, such beneficial traits may become widespread within the gene pool. Similarly, certain alleles can become fixed in the population, which means every individual carries that allele, as it offers a significant reproductive advantage.

An allele frequency can change via natural selection when the allele provides a phenotype that enhances survival or reproductive success. Such alleles will be in greater frequency in subsequent generations, potentially leading to fixation of the allele in the population and a corresponding decrease in other alleles.

Final answer:

Beneficial mutations are more likely to become common in a population through natural selection by helping organisms adapt and increase their chances of survival and reproduction.

Explanation:

Beneficial mutations are more likely to become common in a population through natural selection. Beneficial mutations are mutations that have a positive effect on the organism, helping it to better adapt to changes in the environment. These mutations increase the organism's chances of surviving or reproducing, making them more likely to be passed on to future generations and become more common in the population over time.

Harlem Renaissance in upper Manhattan

Explanation:

Final answer:

Zora Neale Hurston and Langston Hughes were influential figures in the Harlem Renaissance, a period of African American cultural expression in the 1920s and 1930s. Their works celebrated African American heritage, addressed racial prejudice, and laid a foundation for future American art and literature.

Explanation:

Harlem Renaissance Luminaries: Zora Neale Hurston and Langston Hughes

Zora Neale Hurston and Langston Hughes were prominent figures who flourished during the Harlem Renaissance, a vibrant period of African American cultural expression that began around 1920 and extended into the mid-1930s. Hughes was widely recognized as a prolific writer, leaving a significant mark with his poems such as "The Negro Speaks of Rivers" and "I, Too, Sing America," which celebrated African-American heritage and the resilient spirit of the community. Hurston, although her most famous novel "Their Eyes Were Watching God" was published in 1937, was a key literary figure whose work depicted the life and dialect of rural black communities, celebrating black dialogue and addressing racial prejudice and stereotypes. Together, these artists contributed to the creation of a unique and independent black culture that fueled racial pride and was distinct from the emulation of European or white American cultural norms.

Their works, among others, laid the groundwork for a new American literary and artistic landscape, rejecting European standards that had previously dominated and instead forging an original path that would inspire future generations. Not only did they address the struggles of black Americans, but they also countered pervasive racial stereotypes and encouraged African Americans to band together to fight against racial prejudice. The Harlem Renaissance was marked by such literary and artistic achievements, and it stood as a dynamic era of creativity and self-expression that profoundly influenced American art, literature, and culture.
