Genetic recombination is the interchange of genetic material across organisms, resulting in offspring with unique features. Therefore, option (C) is correct.
What is recombination?The exchange of genetic material between distinct species, or genetic recombination, produces offspring with features that are different from those of either parent is called recombination.
Chromosome arms may touch during the alignment and momentarily merge, leading to a crossover. Recombination and the transfer of genetic material between the maternal and paternal chromosomes occur as a result of crossovers. As a result, a child's gene combinations may differ from those of their parents.
As a result of genetic recombinations, the species integrity—an essential structure responsible for the preservation and improvement of ecological stability of animals in developing lineages—is continuously homogenized within the species.

Answer:
Explanation:
Because they are all 4 rocky planets in the solar system, I did it when i was in 4th grade during my solar system project
The Venus, Earth, and Mars compare to each other because they are all 4 rocky planets in the solar system.
What is the solar system?The Sun and the objects that orbit it make up the gravitationally bound system known as the Solar System. The massive interstellar molecular cloud's gravitational collapse resulted in its formation 4.6 billion years ago.
Our planetary group comprises of our star, the Sun, and everything bound to it by gravity - the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; planets as small as Pluto; a lot of moons; and millions of meteorites, asteroids, and comets.
The fundamental thought of the planetary group was proposed by the Clean stargazer Nicolaus Copernicus (1473-1543) who said that "the Sun is the focal point of the Universe" and made the planets move around it in amazing circles.

En una isla oceánica aislada hay una especie de pájaros, la
mayoría de plumaje gris. Una variedad con manchas blancas
constituye el 4% de la población. Esta característica se debe a un
gene recesivo (s) al del plumaje de color gris entero (S).
¿En qué frecuencia se encuentra el gene s?
a 0.3
b 0.2
c 0.1
d 0.05
Answer:
La frecuencia del alelo recesivo s es igual a 0.2 (opción b)
Explanation:
Datos disponibles:
Plumaje gris es el fenotipo dominantePlumaje con manchas blancas es el fenotipo recesivoS es el alelo dominante para plumaje griss es el alelo recesivo para plumaje manchadoVariedad manchada representa el 4% de la población.Si ejemplares con ala manchada y genotipo ss representan el 4% de la población, entonces los restantes 96% corresponden a ejemplares grises homocigotas dominantes SS y heterocigotas Ss. Las frecuencias fenotípicas serán:
Plumaje gris (SS + Ss) = 96% = 0.96Plumaje manchado (ss) = 4% = 0.04De acuerdo al equilibrio de Hardy-Winberg, la suma de las frecuencias alélicas equivale a 1, y la suma de las frecuencias genotípicas también equivale a 1.
Frecuencia del alelo dominante = pFrecuencia del alelo recesivo = qFrecuencia de genotipo homocigota dominante = p²Frecuencia de genotipo heterocigota = 2xpxqFrecuencia del genotipo homocigota recesivo = q²Entonces,
p + q = 1p² + 2pq + q² = 1Si la frecuencia genotípica del homocigota recesivo es 0.04, entonces la raíz cuadrada de ese valor es la frecuencia génica del alelo recesivo. Esto es:
q² = 0.04q = √0.04 = 0.2A partir de la ecuación p + q = 1, podemos calcular el valor de p.
p + q = 1
p + 0.2 = 1
p = 1 - 0.2
p = 0.8
Entonces la frecuencia genotípica del homocigota dominante es p²
p² = 0.8² = 0.64
Y la frecuencia genotípica del heterocigota es
2pq = 2 x p x q = 2 x 0.8 x 0.2 = 0.32
Para corroborar esto, la suma de todas las frecuencias genotípicas debe dar uno.
0.64 + 0.32 + 0.04 = 1
A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and molluscs is removed from the oceanic food chain to become part of another, slower carbon reservoir.
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink.
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.
CO2 is not combustible. creates carbonic acid in the oceans. Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)If helpful, please mark as brainliest! =)

Explain in detail how CONVECTION heat transfer effects our weather?
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.
Explanation:
Answer:
convection occurs over a very very long time in the earth's mantle. Rock slowly gets melted down from the core, then shoots back up from volcanoes. The new rocks get buried by sand and sediments, and the process resets.

How can planting a large area of just one variety of plant cause problems for both a farmer and an ecosystem?
Answer:
Particular plants use particular nutrients from the soil. If you were to consistently plant a large number of plants, of the same species, in the same area. The plant will use all of the nutrients it needs, before the nutrients are replenished. This can cause a decrease in the farmer's yield. By doing this you also create a habbitat for pests. Some pests live off to certain plants, so if your not planting other crops, the pests will thrive. Plating a variety of crops is good because some plants will repel pests from other crops that the pests may be attracted too.

Explanation:
A mutation is least likely to affect a cell when the mutation --
A mutation is least likely to affect a cell when the mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.
What is the function of cells and mutation?As genetic materials, nucleic acids encode information about the cell's structure and function, its proteins, receptors, and so on. The mRNA that is formed from the gene has roles in the formation of the receptor, the enzymes, etc., so if any mutation happens to the gene that is in the coding region, then it can show its impact, but if the mutation is of the silent type, then it has no impact on the cell.
Hence, when a mutation is silent in nature or is not associated with an exon, it is least likely to affect a cell. Any mutation that happens to the introns does not affect the cell's function.

The Rock Cycle is happening all the time on Earth.
Some processes of the Rock Cycle take a long time.
O All rocks were once Metamorphic Rocks.
O Most rocks on Earth are Igneous Rocks.
Answer:All rock were once metamorphic rocks
Explanation:
Melted rock deep inside Earth forms igneous rocks. Sand, silt, plant and animal skeletons make sedimentary rocks. Heat and pressure underground convert rocks into metamorphic rocks. Therefore, option (C) is correct.
What is rock cycle?The rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the various applications of heat and pressure over the course of time. Igneous rocks are rocks that are formed by volcanic eruptions, while metamorphic rocks are formed when heat and pressure are applied to preexisting rocks. Shale, a type of sedimentary rock, can be transformed into slate with the use of heat and pressure, for instance.
The rock cycle is an important component of our dynamic Earth because it allows rocks to shift from one type of rock to another based on their location and circumstances. It recycles rocks to build new structures when plate tectonics changes the Earth's surface.

Usable fresh surface water is relatively scarce. To many people, streams and lakes are the most visible part of the water cycle. Not only do they supply the human population, animals, and plants with the freshwater they need to survive, but they are great places for people to have fun.
Answer:
True.
Explanation:
Usable fresh surface water is scarce. Freshwater is not in excess on our planet. We can find it on lakes, lagoons, rivers, and swamps, but it is only 3% of the totality of Earth's water. The importance of this water is that it is the one that is suitable for humans, a large number of plants, and animals. This is why there are different methods to store and distribute fresh water amongst all the population and places that need it. Besides, the places where freshwater is, are great for activities, such as swimming, sailing, rafting, diving, fishing, etc.
Since freshwater is scarce and has so many uses, we must take care of it.
