Answer:

They are the alkali metals, alkaline earth metals, transition metals, other metals, metalloids, non-metals, halogens, noble gases and rare earth elements.

The chemical elements in the periodic table are organized from left to right and from top to bottom based on the atomic number.

The periodic table of elements also known as the periodic table is an organized alignment of the 118 elements known at present. The arrangement of chemical elements is done from left to right and from top to bottom on the basis of the enhancing atomic number, or the number of protons in the nucleus of an atom that usually coincides with the enhancing atomic mass.

On the periodic table, the horizontal rows are known as periods, in which each period number demonstrates the number of orbitals for the elements in that row.

Thus, the periodic table of elements is organized from left to right and from top to bottom based on the atomic number.

Answer:

Use 400 x in order to study the structure clearly.

Explanation:

Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.

Imagine green and yellow bugs live in the grass. Their predator is the speckled finch. Now, the finch flies down to grab some tasty beetles, and which ones does it go for? The yellow ones. The green beetles, due to their natural grass camouflage will have a much smaller chance of being eaten than the yellow ones which stand out. While the yellow ones get eaten the green thrive and reproduce. Soon, there won't be anymore yellow bugs. They'll most likely die out or breed with the green ones to make offspring of a more green color.

Answer:

Hello. You did not put the options, but we can say that the execution of mitosis is what makes it important that the proportion between the colume and the cell surface area is not small.

Explanation:

The ratio between the surface area of ​​a cell and the volume is very large and this is essential for mitosis to occur and for all cells in the same tissue to have the same content and the same drum.

If a cell increases ten times its surface area, it will increase its volume a thousand times. This shows that the cell volume has a much larger proportion than the surface. This makes the cell have a fast metabolic rate and needs to absorb many nutrients, in addition to making a strong exchange of gases with the external environment. This absorption of nutrients so intense, is essential for the cell to enter mitosis and generate two equal cells. This is because during the growth phase the cell will increase in volume until the growth limit of its surface area, once this limit is reached, the cell will have to undergo mitosis and will have enough nutrients for the entire process.

Answer:

Politics can affect and even dictate the manner in which science is done. For example, passing laws that limit whether embryos can be used in stem cell research. Politics can allocate funding to various scientific causes. Politics can create a great research environment in the universities. And so on.

In extremes, politics can even make entire areas of science off limits. In the early twentieth century, lots of very smart and decent people were eugenicists. Politics (in particular, the unbelievable moral horror that was Nazism and the Holocaust) change

Answer:

Their bodies are covered with a hard armor called the exoskeleton. Most ants are either red or black in color and length can be anywhere from 1/3" to 1/2". Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae, and powerful jaws.

Explanation:

The ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, and the segmented body; apart from that, it has an antenna, etc.

The ants belong to arthropods, and the arthropods are non chordates. The special feature of the arthropods is that their bodies are segmented into three parts, such as the head, thorax, and abdomen, and they have an exoskeleton similar to that of the ant. Ants are eusocial animals, meaning they live in groups. Different types of ants are present in different geographical locations, and some of them produce toxins that are harmful to other animals.

Hence, the ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, the segmented body, etc.

Answer:

1.32°F

2.212°F

Explanation:

1.The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C).

2.Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation.

3.In other words, the water molecules within ice move faster. However, temperature doesn't change as heat is added during a phase change; for example, when the ice melts. During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.

Explanation:

The correct answer would be meat in both jars would have maggots.

If maggots were spontaneously being produced by meat, both of the meat in a sealed and opened jar would have maggots in them. A spontaneous process would happen without any external force. Hence, whether the jar is sealed or otherwise, the spontaneous appearance of maggots in a jar with meat would still happen.

The correct option is C.
