What kind of rock is this?
igneous
Where would this rock most likely be formed?
To which group of rocks would this rock belong?
Rocks can be classified based on texture. The
size of the grains in a rock affects its texture.
Coarse-grained rocks have large grains, and fine-
grained rocks have small grains.
Rocks formed from magma under Earth's surface
have larger grains than rocks formed from lava
on Earth's surface. This is because magma cools
slower underneath the ground than it does above
ground.

Answer:

if  An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.

Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.

The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.

The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.

Answer: people with sickle cell trait have a better chance of surviving malaria.

Explanation:

Malaria is a very prevalent disease in the malaria belt of Sub-Saharan Africa which includes much of western and central Africa. The people here have therefore grown to have better immunity to malaria by developing the sickle cell trait.

This has helped them survive both malaria and sickle cell anemia which doesn't affect them even though they carry the sickle cell trait.

Answer:

We should expect that the fruits should grow in population and spread more easily.

Explanation:

Like the relationship between bamboo and pandas, the relationship between the seeds and the beaks of birds should allow the seeds to spread to other areas more easily that would otherwise be a very gradual process if the seeds did not evolve its viscous ability.

Answer:

the forces between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them

Answer:

The force becomes 4 times as much when the distance is halved.

Explanation:

F1 = k*q1 * q2/r^2 = kq^2/r^2

F2 = kq^2/1 / (r/2)^2

Set up a proportion using F1/F2 as you reference.

Notice that you don't know any number that can be used in this equation. However k q^2 does not change as you move the two charges closer together. That being so, you can still show what happens to F1 and F2.

F1/F2 = 1/r^2 // 1/(r^2/4)

Take the denominator, invert the fraction and multiply. That creates another cancellation.

F1/F2 = 1/r^2 * r^2 /4 1

F1/F2 = r^2 // r^2/4          which allows you to cancel r^2

F1/F2 = 1/4                       Now you need to interpret F1 and F2. Cross Multiply

4F1 = F2

Explanation:

The introduction of nonnative species in an ecosystem maybe both helpful and harmful. Initially, the introduced nonnative species maybe prove helpful in some ways.

As time goes on, the nonnative species begin to compete with the native species for resources in the ecosystem. The nonnative species may outdo the native species in such competition and entirely replace them. This may ultimately lead to a permanent loss of the native species from the ecosystem.

Answer:

Mutation can disrupt the cell cycle.

Answer:

The correct answer is - chemical signals between cells, transported in blood or hemolymph

Explanation:

Hormones are chemicals that make communication between cells and transfer the signals to various target cells. These are transported through the blood and lumph in their respective circulation so signals can reach to the surface or within the target cells and perform specific functions.

Answer:

Explanation:

Therefore, there will be two daughter cells at the end of mitosis. Each will have 10 chromosomes, if the parent cell has 10. The chromsomes will not have sister chromatids because after mitosis, the duplicated pairs have separated into the two daughter cells. The cells will each be diploid, just as the parent cell was.

Explanation:

If a cell has 10 chromosomes when it begins mitosis, there are 15 will have immediately afterword.

Answer:

a) Presencia de un catalizador

Explanation:

Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.

Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.

Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.

La evidencia de que ha tenido lugar un cambio químico incluye

1) La formación de un precipitado a partir de la mezcla de sustancias.

2) Un cambio en el color de las sustancias.

3) Un cambio en el olfato (que desprende un olor) o en el sabor.

4) La sustancia produce luz (brilla)

5) El volumen total cambia

6) Cambio de temperatura (la mezcla se calienta o enfría)

Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

Answer:

Controlled variable=coloured water

Dependant variable=amount of water

Independant variable=narrow and wide straw

Explanation:

Have a nice day

Answer:

The controlled variable is straws. Independent it the water and dependent is the capillary action.

Explanation:

The Independent variable is the water because its not chaninging thorughout the experiment and has no conqueunces on the other varibales.  The controlled is the straws because you are controlling the different diameters in which the straws are (narrow/wide). Then as you change your controlled variable your dependent varible will change- which is the affect on capillary action.
