explain the following type of respiration with diagram in toad:
1..Buccal respiration
2..Cutaneous respiration
3.. Pulmonary respiration​

Answers

Answer 1

Answer:

1.Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent.

2.Cutaneous respiration, or cutaneous gas exchange, is a form of respiration in which gas exchange occurs across the skin or outer integument of an organism rather than gills or lungs.

3.Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation.

These levels are higher than at any time in the last 800,000 years, and it has been estimated that in 2025 the CO2 levels will be higher than at any time in the last 3.3 million years. In 2018, there has been an increase of approx. 2.5 ppm, the same increase observed between 2017 and 2018. Moreover, the average increase of the CO2 levels in the atmosphere between 2009 and 2018 was 2.3 ppm each year.

How did a famous event change the course of the American Revolutionary War? in essay form pls

Answers

Answer:

The American Revolution was a political battle that took place between 1765 and 1783 during which colonists in the Thirteen American Colonies rejected the British monarchy and aristocracy, overthrew the authority of Great Britain, and founded the United States of America. See the fact file below for more information and American Revolution facts.

-The American Revolution, also known as the Revolutionary War, began in 1775.

-British soldiers and American patriots started the war with battles at Lexington and Concord, Massachusetts.Colonists in America wanted independence from England.

-The British government attempted to pass some laws, enforce several taxes, and increase more control over the colonies.

-The colonies strongly objected to these laws and taxes.

-They wanted England to have no control over them.

-For ten years before the war actually started, there was a lot of tension between England and the colonies.

-The colonies had no central government at the beginning of the war, so delegates from all the colonies were sent to form the first Continental Congress.

-George Washington, a former military officer and wealthy Virginian, was appointed Commander in Chief of the Continental Army.

-Members of the Continental Congress wrote a letter to King George of England outlining their complaints and declaring their independence from England.

-On July 4, 1776, the Continental Congress adopted the Declaration of Independence, in which the colonies declared their independence from England.

-The war ended in 1783, and the United States of America was born.

Which statement describes earthquakes which team explain one way that minerals form

Answers

Earthquakes are natural phenomena characterized by the sudden release of energy in the Earth's crust, resulting in seismic waves that can cause the ground to shake.

During an earthquake, the rocks along the fault experience immense pressure and deformation.

This intense pressure can cause minerals within the rocks to undergo various processes that contribute to their formation.

One way minerals can form as a result of earthquakes is through metamorphism.

Metamorphism is the process by which existing minerals within rocks undergo changes in response to high temperatures, pressures, and deformation.

During an earthquake, the rocks near the fault zone are subjected to extreme pressure and temperature conditions.

The intense stress causes the minerals to recrystallize, rearrange their atomic structures, and form new minerals.

This process is known as dynamic metamorphism or cataclasis.

The newly formed minerals in fault zones can include varieties of quartz, feldspar, mica, and other minerals commonly found in metamorphic rocks.

The specific minerals that form depend on the composition of the original rocks and the conditions present during the earthquake.

Answers

Answer:

The correct answer is the first option:-

The hormone is released into the bloodstream where it can be carried throughout the  body to the target cells with specific receptors.

I learnt in biology that hormones are transported through blood so they reach the specific receptors and act upon them so am sure this is the answer!.

Answers

I think a raccoon because both are predators

In a pond food chain ecosystem, a fish feed on mosquito, a producer. The fish may get eaten by a racoon, which in turn is consumed by a snake. In a pond, algae is autotroph. So the correct option is D (racoon).

What is trophic level in ecosystem?

Trophic level is defined as the ranking of an organism in the food chain and which differ from a value of 1 for primary producers to 5 for marine  humans or mammals.

Racoon is mammal and omnivorous whereas the snake is carnivorous animal.  In a pond ecosystems, the biomass pyramid is inverted.

According to the passage, which of the following topics of study was the most crucial to his final analysis?
The study of statistics and probabilities

The study of plant varieties

The study of agriculture

His study of the experimental method

Answers

Answer: The study of plant varieties.

Explanation:

This question relates to the studies that Gregor Mendel, founder of modern genetics, performed at the University of Vienna.

Experimenting on pea plants, Gregor Mendel was able to establish a lot of the rules of heredity that we know today even though his research was not fully appreciated or understood during his own life.

He credited the study of plant varieties to have been most crucial to his final analysis because farmers had been crossbreeding varieties for millennia to bring about better traits in plants.

Answers

Answer:

The structure and function of cellular proteins and how they interact to contribute to traits.

Explanation:

Proteomics is a research area that studies proteomes and their interactions with other cellular components (e.g., transcription factors involved in DNA-protein interactions, ribonucleoprotein complexes involved in RNA-protein interactions, etc). A proteome can be defined as the entire set of proteins synthesized by an organism. The proteomics field allowed us to identify common protein functions (structural and enzymatic functions), as well as understand how protein expression (which is regulated by genetic and environmental factors) influences cellular metabolic activities (e.g., iron uptake).
