Answer:
photosynthesis
Explanation:
4. Give two examples of how you interact
with the carbon cycle.
Answer:
in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. ... Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.

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.

Answer:
Inner core---Lava---Outer core---Magma---Mantle---Asthenosphere---Oceanic crust---Continental crust---Crust---Lithosphere,
Explanation:
Inner core is the last layer of the earth where lava is present. After that outer core is located where magma is present between outer core and the crust of the earth. After outer core, the layer of mantle is started which extends up to the crust. Asthenosphere is the layer that is present at the upper portion of the mantle and at the top, earth crust is located. Crust and upper portion of the mantle is also known as lithosphere.

Why is it helpful for frogs to have bulging eyes?
Answer:
It is helpful for frogs to have bulging eyes because it allows them to see in all directions such as in front of them, to the sides, and partially behind them. The frog's eyes that are positioned above their head give them a field of vision of almost 180 degrees, this helps them spot predators and prey easier and quicker.

forms there.
Explanation:
Spreading center volcanism occurs at the site of mid-oceanic ridges, where two plates diverage from one another. As the plates are pulled apart, hot ashtenophere rise upward to fill voids of the extended lithosphere.
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! =)
An organism has 50 chromosomes in its body cells, how many chromosomes are in it’s sex cells?
There would be 25 chromosomes in the organism's sex cells, also called gametes.
This is because, during sexual reproduction, two gametes unite to form a zygote. Their chromosomes in this case combine to make 50. (Humans have 46 chromosomes in their body cells and 23 in their gametes.)
In short, the number of chromosomes in the gamete is half the number of chromosomes in the body cells.

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.

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.

Why is the normal range for the mass of DNA in a male cat cell lower than for a female cat?
A
The male cat has less chromosome pairs than the female cat.
B.
The male cat is XY, while the female cat is XX, and the Y chromosome is
smaller than the X.
с
The female has more diploid cells and less haploid cells, so the average
mass of DNA in each female cell is higher.
Answer:
B: The male cat is XY, while the female cat is XX, and the Y chromosome is
smaller than the X.
Explanation:
Y chromosomes are smaller than X chromosomes so the mass of DNA is smaller in male cells than female cells
The Y chromosome is smaller than the X chromosome. So, there is less nucleotide in the DNA of a female cat. Hence, option B is correct
What is DNA?DNA stands for deoxyribonucleic acid and it is a polymer of nucleotides. It is double-stranded in structure. It is hereditary material present in the cells of organisms. Nucleotides consist of pentose sugar, nitrogenous bases, and phosphate.
DNA is organized in the nucleus in the form of dense protein complexes known as chromosomes. 38 chromosomes are present in cats. There are two types of chromosomes in cats X and Y. Male cat contains XY chromosomes and female cat contains XX chromosomes. The Y chromosome is shorter than the X chromosome.
Therefore, the normal range of the mass of DNA in a male cat cell is lower than that of a female cat. Hence, option B is correct

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.

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.

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
