Answer:

C

Explanation:

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.

In the fungal life cycle, karyogamy results in:______.
Vikentia [17]

Answer:

In the fungal life cycle, karyogamy results in D. fungi haploid nuclei from two parent fungi fuse together

Explanation:

Karyogamy has an important role in sexual reproduction. It is the last step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. This is the steps that usually follows the Plasmogamy stage. This step is part of the sexual reproduction of fungi too. Karyogamy is key because it helps recombine two different genetic material.

Trisomy could occur as a result of nondisjunction during meiosis. In order for nondisjunction to lead to trisomy, how many chrom
babunello [35]

Answer:

24 (n+1)

Explanation:

Trisomy refers to the presence of one extra chromosome in the genome of the organism. This means that the affected individuals have a total of 47 chromosomes, instead of 46.  

Nondisjunction during meiosis I or meiosis II produce the gametes with one extra chromosome. For example, nondisjunction in egg mother cell results in the production of some egg cells with "n+1; 24 chromosomes".  

Fertilization of the egg cell carrying 24 chromosomes with a sperm carrying 23 chromosomes forms a trisomic zygote with 47 chromosomes.

I've been stuck on this for I little bit now and could use some help:)
lana [24]

The answer would be:

6,250 joules

Here's how to do it:

KE = \frac{1}{2}mv^{2}

KE = kinetic energy (joules)

m = mass (kg)

v = velocity (m/s)

So with that formula let's figure out what was given to you.

500 kg and 5m/s

You know which is which based on the unit.

m = 500kg

v = 5m/s

Now all you need to do is plug it into your formula and solve.

KE=\frac{1}{2}mv^{2}

KE= \frac{1}{2}(500kg)(5m/s)^{2}

KE = \frac{1}{2}(500kg)(25m^{2/}s^{2})

KE = \frac{1}{2}(12,500kg\cdot m^{2}/s^2})

KE = 6,250kg\cdot m^{2}/s^{2}

The unit kg\cdot m^{2}/s^{2} also means joules

So the final answer is 6,250 joules.
