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.

Answer:

The correct answer is: trilobite.

Explanation:

Trilobites were the most common form of early sea life found in Oklahoma. Trilobites were arthropods that are now extinct. This marine species is thought to have lived during the early Cambrian period and they existed for almost 300 million years, before disappearing at the end of the Permian in the Permian-Triassic extinction event.

Answer:

The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.

Answer:

what are the choices

Explanation:

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.

Explanation:

Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II.

In meiosis II, these chromosomes are further separated into sister chromatids. 

Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

Explanation:

Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.

Answer: Almost all living things need oxygen. They use this oxygen during the process of creating energy in living cells... Animals form other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.

Answer:

Explanation:

If the bacteria is required to be in highly basic conditions, putting it in highly acidic conditions would disrupt the internal functions of the bacteria which tends to kill the bacteria.

The way that bacteria that require a pH of 11 for growth respond, replaced in a pH of 2, will respond in the way: the bacteria must be in extremely basic circumstances, exposing it to excessively acidic settings will disturb its internal functions, eventually killing it.

The optimum pH for bacterial growth may differ. Some bacteria, known as acidophiles, can thrive in an acidic environment, while others, known as alkalinizes, can grow in a base environment, and the remainder, known as neutrophils, can grow in a neutral pH environment.

Bacteria can keep their internal pH stable by creating acid, base, or buffer. If the surrounding pH is too acidic, the bacteria can produce a base to reduce the H+ concentration. If the conditions are excessively alkaline/basic, the bacteria can make acid through fermenting.

Therefore, Bacteria that require a pH of 11 for growth will respond in the following manner: the bacteria must be under extremely basic circumstances; exposing it to highly acidic settings will disrupt its internal functions, finally killing it.

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:

D is the correct answer. (please give me brainliest?)

Social sciences are the disciplines that study human social behaviour or institutions and the functions of human society in a scientific manner. So the correct option is D.

A collection or a group of disciples related to academic disciplines focusing on the behaviours of the individuals within society is called social science. It is the explanation of the working of the society which explores various aspects from economy to psychology.

The study of social science is relatively new in the field of scientific study. It gained popularity in the 20th century. Advertising, economics, psychology, teaching, managing etc are only some of the fields relied on social science.

The people who study social science are called social scientists. They rely more on the interpretation of the information and qualitative aspects of the methodology of methodologies.
