You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.

Answers

Answer:

To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.

First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.

Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.

Answers

The cell duplicates it’s contents at the start of mitosis and only divides one time compared to meiosis that divides 2 times thats why chromosome number is lower in meiosis

Relation between mitosis and chromosomes:

During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.

When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

Crossing over occurs during meiosis and leads to changes in the chromosomes. What type of chromosomes does crossing over produce?
1. Chromosomes containing DNA from two different parental chromosomes
2. Chromosomes identical in genetic makeup to the parental chromosomes
3. Chromosomes containing more genes with non recombinant chromosomes
4. Chromosomes carrying genes from one parent

Answers

Answer:

1.

Explanation:

because the DNA is being mixed up while crossing over

Crossing over occurs during meiosis and leads to chromosomes containing DNA from two different parental chromosomes, hence option 1 is correct.

What is meiosis?

New allelic combinations are created in the daughter cells as a result of the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis.

Homologous chromosomes couple along their lengths during meiosis, one from each parent. At locations known as chiasma, the chromosomes overlap.

The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.

Therefore, the genetic complement in each daughter cell at the end of meiosis is best described as a haploid set of chromosomes resulting from chromosomal recombination between the parents.

What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid

Answers

Answer:

The graphical representation of the age structure is known as age pyramid (option D).

Explanation:

The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.

The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.

In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.

    Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

Which statement describes a law based on a tested hypothesis explains how the process occurs describes something about the natural world subject to change as new evidence is discovered

Answers

Answer:

based on a tested hypothesis

Explanation:

Laws are generally based on tested hypotheses.

Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that cannot be changed.

Scientific laws are internally consistent, compatible with evidence, and are testable against a wide range of phenomenon. However, they can be reviewed as more evidences emerge that have not been known before.

Why were Wegener's ideas about continental drift initially rejected

Answers

Answer:

The main reason that Wegener's hypothesis was not accepted was that he suggested no mechanism for moving the continents.

Explanation:

It wasn't until 1928 that a Scottish Geologist, Arthur Holmes, came up with an explanation for why continents move. He believed that heat traps in the Earth caused convection currents. There were areas where fluids trapped beneath Earth's crust heat up, rise, spread laterally, then cool and drop back down. This hypothesis didn't have a wide acceptance either but was revived in the 1940s and 1950s when scientists started to learn more about the seafloor and the magnetic properties of oceanic crust.

What happens to energy that is transmitted through or reflected off a material?

Answers

The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. ... When this occurs, objects have a tendency to selectively absorb, reflect or transmit light certain frequencies.

When light is transmitted through or reflected off a material, the light is converted into heat.

What is light?

Light is an entity that make things visible to eyes. It is an electromagnetic radiation. It can not be produced or end, it's just converted into one form to another form.

The item may absorb the light wave, in which case its energy is changed to heat. The object might reflect the light wave. Additionally, the object might transmit the light wave. When this happens, things often selectively absorb, reflect, or transmit certain light frequencies.

The light is passed through some objects and do not get passed through some objects. The light that do not pass through an object is reflected back to the same place, but when it is not reflected, it converts into heat.

Therefore, the light is converted into heat when it is not reflected.
