The Sun's radiation provides the energy for all of the following EXCEPT

Answers

Answer:

the answer is D :)

The Sun's radiation provides the energy for all phenomena described EXCEPT plate tectonics.

Solar radiation is radiant energy from the Sun, which represents the main source of energy on Earth.

The lithosphere, which is the crust and upper mantle of the Earth planet, is divided into different tectonic plates.

These plates move due to the heat from radioactive processes within the Earth's (core) interior, thereby solar radiation does not directly provide the input of energy required for this movement.

In conclusion, the Sun's radiation provides the energy for all phenomena described EXCEPT plate tectonics.

how are sex linked traits determined

Answers

Answer:

A sex-linked trait refers to genes that determine a specific structural or functional characteristic and are found on an X or Y sex chromosome.

Explanation:

The X and Y sex chromosomes are what determine the sex of an individual, XY for male and XX for female. A sex chromosome-linked trait refers to specific genes located on one of the sex chromosomes.

In general, the X sex chromosome is capable of having more traits linked to it because it is larger than the Y chromosome.

Genes are what determine the morphological and functional characteristics of an individual. When specific genes are found on a sex chromosome, the traits that they determine will be given to the offspring through that chromosome.

Currently, what is a major source of ocean pollution? How much
more pollution is occurring compared to 1960?
plz help. need this answered 4 science.

Answers

Answer:

Most ocean pollution begins on land.

Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.

Answer:

Plastic pollution: The ocean is estimated to contain millions of tons of plastic debris, much of which comes from land-based sources.Chemical pollution: The ocean is also contaminated with a wide range of chemicals, including pesticides, herbicides, and industrial and household chemicals.Nutrient pollution: Excess nutrients, such as nitrogen and phosphorus, can enter the ocean from agricultural and urban runoff and contribute to the growth of harmful algal blooms.Oil pollution: Oil spills and other oil discharges into the water can have a negative effect on the animals and marine ecosystems there.

A car moves at a speed of 50 kilometers/hour. Its kinetic energy is 400 joules. If the same car moves at a speed of 100 kilometers/hour, then its kinetic energy will be

Answers

Answer:

1601.33J

Explanation:

Kinetic energy = 1/2 × mv²

Where;

m = mass (kg)

v = velocity (m/s)

To calculate the kinetic energy of the same car at a different speed, we initially need to calculate the mass of the car.

The initial velocity of the car is 50km/hr = 13.89m/s, while the kinetic energy is 400Joules

K.E = 1/2 × mv²

400 = 1/2 × m × 13.89²

400 = 1/2 × m × 192.93

400 = 96.466m

m = 400/96.466

m = 4.15kg

Mass of the car is 4.15kg

K.E = 1/2mv²

If velocity = 100 kilometers/hour = 27.78m/s

K.E = 1/2 × 4.15 × 27.78²

K.E = 1/2 × 3202.67

K.E = 1601.33J

Answer:

1600j

Explanation:

ke prop to v^2

ke1/v1^2=ke2/v2^2

400/50x50=joules/100x100

How is metaphase of mitosis different from metaphase I of meiosis?

Answers

Answer:

Metaphase I in Meiosis

The homologous pair is a representation of the same DNA but has different alleles. The homologous pairs will attach to each other during metaphase I and they undergo the alignment on the metaphase plate, unlike in mitosis where the sister chromatids are the ones that align on the metaphase plate.

In metaphase I of meiosis they undergo the alignment on the metaphase plate, unlike in mitosis where the sister chromatids are the ones that align on the metaphase plate.

If a company developed a way to modify a person's DNA to guarantee certain attributes in offspring, should that company be forced to make their technology available to everyone who wanted it? What are some of the ramifications of widespread use of this type of genetic engineering technology on humankind?​

Answers

Yes, however, random people should not just be taught because people have a tendency to not follow every step, and can hurt themselves. I learned about this, and that if you modify a persons DNA, that's permanent. If you messed up, your offspring could be impacted. This is why we don't just give out information, because people are afraid that if we messed up, we could end the world or something.
