Answer: Helium atoms  

Explanation: The reaction taking place at the Sun is nuclear fusion reaction. It is a process where two or more atoms combine leading to formation of a new atoms. But here total mass of the reactants is not equal to total mass of the products. Some of the mass is lost as energy and this energy is produced in very enormous amount. At the Sun, four H atoms combine and form helium atoms. Along with this large amount of energy is produced which is responsible for huge amount of heat at the Sun.

 MRSA have prokaryotic structure

MRSA can also be refers to as methicillin resistant staphyloccous aureus and known to be strain of staphyloccous aureus.  Also, they are characterized by their resistance to antibiotics methicillin. However, prokaryotic cell are known to be less complex cell with visible structure and they are also characterized by nucleus absent.

Answer is D.

There are many reasons for the rapid population growth rate in most developing countries is higher than in developed countries. Some of the major ones are: Women are least educated and they don't have easy access to birth control measures. Developing countries depend on agriculture and other farming activities. Children can be put to work at a young age to do these jobs. So, to improve economic condition of their families. Therefore, high fertility rate may not account to high population growth rate in most developing countries.

Using a Punnett square, crossing a heterozygous green pod plant (Gg) with a yellow pod plant (gg) will result in a 1:1 genotypic and phenotypic ratio of green to yellow pods due to the dominance of the green allele.

When crossing a plant that is heterozygous for green pods (Gg) with a plant that has yellow pods (which is the recessive phenotype, so the genotype would be gg), we need to set up a Punnett square to predict the genotypes and phenotypes of the offspring. The parent with green pods has one allele for green (G) and one for yellow (g), while the yellow-podded plant has two alleles for yellow (gg).

The Punnett square will have two rows and two columns, with the alleles from one parent along the top and the alleles from the other parent along the side. After filling in the Punnett square, the expected genotypes for the offspring would be Gg and gg. This means that there will be a 1:1 ratio of heterozygous green pods to homozygous yellow pods in the offspring. Since green is the dominant trait, the phenotypic ratio will also be 1:1, showing an equal number of green and yellow pods.

What are the differences between plant and animal mitosis? The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.

In animal cells, cytokinesis occurs through cleavage furrow formation, while in plant cells, it involves the formation of a cell plate.

In animal cells, cytokinesis occurs through the process of cleavage furrow formation. The plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form. On the other hand, in plant cells, cytokinesis involves the formation of a cell plate along the equator of the parent cell. This cell plate eventually develops into a new cell wall that separates the two daughter cells.

Final answer:

The organisms on the island are likely slightly different than the mainland population due to their isolation and unique evolutionary pressures, resulting in speciation and the development of endemic species. The most likely true statement regarding the organisms within the populations is: A. The organisms on the island are slightly different than those on the mainland.

Explanation:

The organisms on the island are most likely slightly different than those on the mainland. This phenomenon is consistent with the principles of island biogeography, where isolated populations experience different environmental pressures and evolutionary paths, resulting in speciation or the development of endemic species. This has been observed in examples across the world, such as the marsupials of Australia, the finches of the Galápagos Islands, and the diverse species of the Hawaiian Islands. These species began as similar to their mainland ancestors but evolved uniquely due to their isolated conditions. The concept of a mainland-island metapopulation suggests the mainland may act as a source for genetic diversity, while the island populations evolve independently. Over hundreds of years of separation, the organisms on the island likely adapted to new challenges, leading to slight differences as compared to their mainland counterparts.

A tiny, stony object that orbits the Sun is called an comet. Hence option 2 is correct.

Asteroid is defined as a remains of our solar system's early development, which are stony, airless objects that date back around 4.6 billion years. There are 1,113,527 known asteroids as of right moment. Astrogeologists have estimated that 60 objects of a diameter of at least 5 km  have struck the Earth within the previous 600 million years based on rates of crater creation found on the Moon, the Earth's closest celestial neighbor.

Comets are tiny, asymmetrical entities in the solar system that are mostly made of ice and dust. They are typically a few kilometers across. They orbit the sun on extremely elliptical paths that first take them past Neptune and then get them quite near to the Sun. The Sun is orbited by planets, dwarf planets, asteroids, and comets. These things don't produce any light. They instead reflect the sunlight.

Thus, a tiny, stony object that orbits the Sun is called an comet. Hence option 2 is correct.

Over the decades local and global ice ages have lowered sea levels. As a result, there is often a decline in marine diversity due to - factors like salinity and temperature of water.

Salinity is the measure of the amount of salt present in any ocean or sea water. High salinity makes it impossible for marine life to survive. Similarly, the temperature of water should be maintained according to every organism's need. Like- Deep sea has a low temperature as compared to shallow sea, due to sunlight. So, deep sea creatures cannot survive in shallow water temperature and shallow water creatures cannot survive in deep sea.

Reforestation and reclamation are both processes that involve restoring and improving land by restoring vegetation and biodiversity.

Reforestation and reclamation are both processes that involve restoring and improving land.

Reforestation refers to the process of planting trees in an area that has been deforested or damaged by human activities. It aims to restore the natural forest ecosystem and increase biodiversity. For example, reforestation projects could involve planting a variety of tree species to recreate a diverse and healthy forest.

Reclamation involves restoring land that has been disturbed or damaged by activities such as mining or construction. It may include activities like soil remediation and reestablishing vegetation. An example of reclamation is when a former mining site is rehabilitated and turned into a natural habitat or farmland.

Although reforestation and reclamation have different focuses, they both aim to rehabilitate and improve the environment by restoring vegetation and biodiversity.

Final answer:

The Great Sphinx and the pyramids of Giza were constructed using limestone from the Giza plateau and nearby quarries, with the pyramids also incorporating granite. These structures showcase the sophisticated engineering and state organization of Old Kingdom Egypt.

Explanation:

The Great Sphinx and the pyramids of Giza are timeless monuments, testament to the Ancient Egyptian's architectural prowess and the geological resources available to them. The Great Sphinx is hewn from the native limestone at the Giza plateau. These layers would also provide the stone for the core blocks of the Sphinx's associated temple. The nearby pyramids, including the largest which is the Great Pyramid of Khufu, are colossal structures constructed predominantly from limestone blocks, with some granite for internal passageways and chambers, originating from nearby quarries. The pyramid constructions required meticulous planning and precise architecture, a reflection of the sophisticated state apparatus of Old Kingdom Egypt. These structures not only served as burial chambers but also signified the might and divine right of the pharaohs, and stand till this day as symbols of Egypt's grandeur.
