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.

Explain the forces that push or pull the continents
Explanation:
We recently learned this in science class and my teacher said that Wegener had proof, except he couldn't explain why the continents were moving. Now, we know of this as the theory of Plate Tectonics, but in Wegener's time, they thought the Earth was shrinking like a raisin.

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

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.

The diagram above shows how sea breezes form clouds in coastal areas. Which map below shows a cloud pattern that would most likely result from the sea breeze cycle in late afternoon?
Answer: Map H
Explanation:
Sea breeze cycle clouds form in an area where land and a body of water such as an ocean or sea come into contact with each other so maps G and J are not possible as these formed over land and away from any coastlines.
These clouds form over land as it is on land that the sea breeze would be warmed by the land temperature and then rise up. Map F is therefore incorrect as those clouds are over the sea.
Map H is the most plausible answer as the clouds are right over land and the area is next to the ocean.

2. Which of the following describes a negative feedback system?
running cattle increase panic within a herd
microphone speaker feedback
feedback that magnifies output
feedback that regulates and stabilizes
Answer:
Feedback that regulates and stabilizes
Explanation:
Negative feedback systems are ones that try to always maintain homeostasis, or a certain state.
For example, the regulation of body temperature in humans is a negative feedback loop. This is because the body maintains a constant temperature at homeostasis, and will adjust if it is too hot or cold.
Feedback that regulates and stabilizes is a negative feedback system, because it involves regulation/stabilization, similar to the regulation of body temperature.
So, the correct answer is Feedback that regulates and stabilizes
Answer:

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.

Explanation:
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

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.
