Explanation:

The atmosphere has zones and each zones has it characteristics with respect to atmospheric conditions such as temperature, pressure and humidity.

So, the question only asked us to compare or show the temperature describe what happens to the temperature as altitude increases in each region of the atmosphere.

(1). Troposphere: the region known as troposphere in the atmosphere has a lower Temperature. The troposphere is a region in which the earth gets its radiation and re-radiates its electromagnetic radiation to give heat which later cools down.

(2). Stratosphere: what occurs in the region known as the stratosphere in the atmosphere is that there will be absorption of UV by the O3 layer which will in turn INCREASES THE TEMPERATURE.

(c). The Mesosphere: in this region of the atmosphere the temperature DECREASES.

(d). Thermosphere: there is surely an INCREASE IN TEMPERATURE in this region because of solar radiation.

(e). Exosphere: there is an INCREASE IN TEMPERATURE in this region too and the temperature increament is caused by ionization.

(f). Ionosphere: in this region, we have an INCREASE IN TEMPERATURE too be side of the solar radiation.

Answer:

A. It decreases the activation energy needed to start the reaction

Explanation:

Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place

When this occurs the minimum amount of  energy of  reaction to  activate or stimulate  the the atoms and molecules of the substrate to undergo chemical reaction is  lowered.This energy of reaction is celled activation energy.

Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation  energy.

Answer:

When viewing a specimen in a microscope, what allows to physically see the image are both lenses, eyepiece and objective.

Explanation:

In optical microscopy, the lenses used to observe microscopic samples play an important role and are necessary for the study of such samples.

- An objective lens is the first to capture the image, providing clarity and proper focus, as well as eliminating color or shape distortions.

- Eyepiece lens obtains the image provided by the objective lens and enlarges it, so that the observer can appreciate the characteristics of the specimen studied.

Explanation:

The scientists believe the continents formed Pangaea about 300 million years ago. The correct option is C.

According to National Geographic, the Pangaea theory proposed that the tectonic plates that make up the planet's external crust glided over the inner layers until they consolidated as a landmass encircled by a huge ocean called Panthalassa.

After a while, the Angaran continent near the North Pole began to move south and combined with the northern part of the expanding Euramerican continent, forming the Pangea supercontinent. This process was completed approximately 300 million years ago.

Alfred Wegener observed the same thing in 1912 and proposed that the continents were once scaled down into a single protocontinent known as Pangaea.

Thus, the correct option is C.

Question:

Match the eukaryotic kingdom with the appropriate description

Fungi

Plants

Animal

Protists

Answer:

Explanation:

All plants and animals are multicellular organisms. Plants are autotrophs, meaning they can make their own food (usually by photosynthesis). In contrast, animals rely on other organisms as a food source (are heterotrophs)

Fungi and protists are more variable. Protists are mostly small unicellular organisms, some perform photosynthesis to make their own food, others eat other organisms.

Fungi usually consume dead or decaying matter (decomposers)

The criminal justice system cannot function without the contributions of forensic science. Forensic scientists collect evidence from crime scenes and other locations, assess that evidence, and then create objective conclusions based on their findings. These conclusions can either aid in the investigation and conviction of criminals or clear an innocent individual of any wrongdoing.

Studies of handwriting for forensic purposes are an essential component of the legal system. These examinations seek to ascertain whether or not handwritten documents can be traced to particular writers by making a comparison to known exemplars of that handwriting.

Answer:

c.

Explanation:

Because youcaring electrons from photosystem II, to photosystem I, to NADP+

I took this test about it hope that helps :D

The role of the electron transport chain in the process of photosynthesis will be carrying electrons from photosystem 1, to photosystem to NADP. The correct option is C.

An electron transport chain is a collection of protein complexes and certain other compounds that donate electrons from electron donors to electron acceptors via redox reactions and couple this electron transfer with the transfer of protons across a membrane.

Photosystems I and II are protein complexes found in the thylakoid membrane.

Their function is to capture high energy electrons from chlorophyll and pass them on to a series of electron carriers before splitting water to form oxygen and hydrogen ions and producing NADPH.

Electron transport contributes to the formation of a proton gradient, which drives ATP production and also stores energy in the reduced coenzyme NADPH.

This energy is used to power the Calvin Cycle, which produces sugar and other carbohydrates.

Thus, the correct option is C.

Presence of the Mitochondrion!!

Explanation:

~

A characteristic common to eukaryotic cells that are not found in prokaryotic cells is the presence of mitochondria. Thus, the correct option for this question is D.

A prokaryotic cell may be defined as a type of cell which is present in prokaryotes. This type of cell typically lacks a well-defined nucleus and other membrane-bound cell organelles. Organisms like bacteria, archaea, etc. possess this type of cell.

All prokaryotes and eukaryotes have a cell membrane known as a Plasma membrane. Most prokaryotic organisms have a small amount of genetic material in the form of a single molecule known as circular DNA.

Protein synthesis is one of the essential functions of all cell types. Ribosomes are significantly found in every type of eukaryotic as well as prokaryotic organisms like bacteria.

Therefore, the presence of mitochondria is a characteristic that is only common to eukaryotic cells but is not found in prokaryotic cells.

Answer:

1. c. virus attaches to cell surface

2. b. virus penetrates and inserts genome into cell

3. f. viral proteins are synthesized within host cell

4. a. viral genome is replicated using host cell's machinery

5. d. new viruses are assembled within host cell

6.  e. the cell ruptures and releases new viruses to infect new  cells

Explanation:

First, the virus attaches to the cell. Then it penetrates the cell membrane and inserts its genome inside the cell. The virus relies on the cell machinery to synthesize its proteins, and also to replicate its genome.

With these components being synthesized and replicated, new viral particles are assembled inside the host cell. Eventually, the cell ruptures, and the newly assembled viruses are released and able to attach to new cells to repeat the cycle

Answer:

The cell membrane controls the substances that enter and exit the cell

Explanation:

The cell membrane defines the boundaries of the cell, separating the internal components from the external environment.

The membrane is a semi-permeable barrier that lets some substances in and out, but not others.

Therefore, the cell membrane controls many of the activities of the cell. As a result, it is crucial to maintain the normal functioning of the organism

EXERCISE

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.

In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).

The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
