Answers

Answer:

Bacterial transformation is the transfer of free DNA released from a donor bacterium into the extracellular environment that results in assimilation and usually an expression of the newly acquired trait in a recipient bacterium

Explanation:

Answer:

Bacteria take DNA from their environment.

Explanation:

Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. ... The prerequisite for bacteria to undergo transformation is its ability to take up free, extracellular genetic material. Such bacteria are termed as competent cells

Which step is meiosis is shown in the image below ?

Answers

Anaphase I of meiosis in shown in this image.

What do you mean by meiosis?

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.

Which choice gives the order of a chain of events that show cause and effect relationships that results from human activity?

A. increased carbon dioxide in the atmosphere; increased water vapor in the atmosphere; increase in severe storms; increase flooding

B. increased water vapor in the atmosphere; increase in severe storms; increased carbon dioxide in the atmosphere; increase flooding

C. increased water vapor in the atmosphere; increased carbon dioxide in the atmosphere; increase in severe storms; increase flooding

D. increased carbon dioxide in the atmosphere; increase flooding; increased water vapor in the atmosphere; increase in severe storms

Answers

Answer:

D

Explanation

carbon dioxide is enhanced by human activity as it icrease it leads to many consequences so B and C are canceled

increasing carbon dioxide does not increase the water vapor immediatly

so A is canceled

so the left answer will be D

The choice that provides the ordering of the chain of events should be option D where the carbon dioxide should be increased.

What is carbon dioxide?

It should be treated as colorless and nonflammable gas at the normal temperature and the pressure. Also it comprise of one carbon atom and 2 oxygen atoms. Here it should be enhanced by the human activity due to which the flooding should be increased, water vapor is also increased also the storms too.

Therefore, the option d is correct.

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by -

Answers

Answer:

The correct answer is - increasing the rate of cellular respiration in the mitochondria.

Explanation:

During the infection, the body of mammals increases its temperature to kill the pathogens that normally die at high temperatures. To increase the body temperature our body promotes the rate of cellular respiration in the cells to produce more energy.

Cellular respiration is the process that helps in converting stored energy into a form of useable energy for the cell which is  ATP. It takes place in the mitochondria of the cell which is called as the powerhouse of the cell and all the function related to energy or ATP is conducted by here.

Answers

Answer: All organisms need energy. ...

Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. ...

Heterotrophs (consumers) obtain energy by consuming other organisms. ...

The flow of energy in an ecosystem can be represented with a food chain or food web

Explanation: A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. A consumer is an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources. Consumers are also called heterotrophs, or other-feeders Producers

Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react 4these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.

1. A cinder cone is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or cinder that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.

FORMS : Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.

2. Lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.

FORMS : Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot.

3. A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground.

Lavas, particularly basaltic ones, come in two primary types: pahoehoe (pronounced 'paw-hoey-hoey") and aa (pronounced "ah-ah"). Both names, like a number of volcanological terms, are of Hawaiian origin. A third type, pillow lava, forms during submarine eruptions.
Answer
Volcano A - Cinder Cone Volcano
Volcano B - Composite Volcano
Volcano C - Shield Volcano

4. Cinder cones are known for their very violent, explosive, exciting eruptions. (A)

Composite volcanoes are explosive, towering giants. (B)

Shield volcanoes quietly produce broad, massive structures through lava flows. (C)

5. Composite volcanoes have very sticky and thick lava, which can make them very explosive when they erupt: gas bubbles that are trapped in the magma chamber find it hard to escape through the viscous rock. They can also spurt lots of hot ash and rocks into the air, making them extremely dangerous.

movement of water molecules be? *
(1 Point)
a) Into the cell.
b) Out of the cell.

Answers

Answer:

a) Into the cell.

Explanation:

The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.

justify that fluorine cannot exist monoatomic from nature​

Answers

Answer:

Due to incomplete outermost shell.

Explanation:

Fluorine cannot exist monoatomic in nature​ because of its incomplete outermost shell. This incomplete outermost shell makes Fluorine more reactive and it can only be stable if it makes bond with other atoms through sharing of electron i. e. covalent bond or by complete transfer of electron i. e. ionic bond. This bond making completes its outermost shell and the Fluorine attain stability so that's why the Fluorine cannot exists in monoatomic in nature.

Hillsdale and Cordera are the same distance from the equator, and both are near the ocean. Is Cordera warmer, colder, or the same temperature as Hillsdale? Explain why as completely as you can.

Answers

Answer:

it is expected that Hillsdale and Cordera have nearly similar temperatures.

Explanation:

In the first place, it is important to note that there is an inverse relationship between latitude and temperature: temperatures are typically warmer near the Equator (lower latitudes) and cooler near the poles (higher latitudes). This phenomenon is due to the fact that the angle of solar radiation is smaller at higher latitudes, and thereby less solar radiation is received/absorbed near the poles than at the Equator. Moreover, another important factor that also determines the temperature is altitude: at higher altitudes, the temperature is lower. This phenomenon is due to the fact that at higher altitude air molecules spread out further, and therefore the temperature decreases. In consequence, at the sea level, the temperature is higher than at higher altitudes.

What would happen to the food that someone ate if they didnt have the digestive enzymes they needed

Answers

Answer:

The digestive system is my favorite system! Without it you would not survive. Our digestive system is how we break down food into nutrients that feed our cells and give us energy to move, talk, grow, think, reproduce, and all the other crazy things that humans do.

Although each of the parts of the digestive system has specific and important functions, shockingly, you can survive without some of the parts. For example, morbidly obese individuals can have their stomach entirely removed in a procedure called a gastric bypass. In this surgery, the small intestine is linked directly to the esophagus thus “bypassing” the stomach. You can also live without your appendix. In fact, it sometimes negatively impacts health as it can become infected (have you ever known someone who had their appendix burst?). The appendix was thought to be a “vestigial organ” meaning that at one point in evolutionary history, we humans had a need for it, but now we don’t; however, there is recent evidence that the appendix is an important hotbed for beneficial bacteria that help us digest food.

Explanation:

I hope this helps! Brainliest is always appreciated!

Answer:

They wouldn't be able to digest the food. It wouldn't break down like it's supposed to with the digestive enzymes.

On the image, which letter represents the enzyme?

Answers

Answer:The correct answer is B

Explanation:

I hope this helps you out!

From the image, the letter that represents the enzyme is B.

Enzymes are substances, made up of proteins, which are capable of speeding up the metabolic reactions in the human body.

There is a theory that explains the mechanism of action of enzymes. This is called the enzyme lock and key theory.

This theory states that enzymes bind to substrates temporarily forming enzyme-substrate complex that appears like the fitting of a lock and key.

This simply means that the same way a particular key can only fit into a particular lock is the same way a particular substrate must combine with  a particular enzyme for a reaction to occur.

From the diagram,

B represents the enzyme with an active site which must fit into a substrate

A represents the substrate.

Therefore, the the letter that represents the enzyme is B.
