functions of bowman's capsule and materials absorbed in the bowman's capsule

Answers

Answer: The structural and functional unit of the kidney is called a nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowman’s capsule and a tuft of leaky blood vessels encapsulated by the Bowman’s capsule.

Glomerulus capsule is a tuft of capillaries that are found inside the capsule of Bowman. Bowman’s capsule is a sac-like organ that is present at the nephron’s tabular end, encapsulating glomerulus in it.

The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomerulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea, etc.

what is the advantage of plasmolysis to the terrestrial plants?​

Answers

Answer:

plasmolysis make the plants floopy, when water passes out through osmosis the plant become limb

Answer:

The cell can be restored quickly to its normal turgid condition simply by returning it to a dilute medium or water.
However, plasmolysis prevents normal water balance and other functions of the plant as a whole, and thus plants cannot tolerate prolonged exposure to medium more concentrated than their own cells.

Inherited traits

Reason they get use to their environment

Having dimples (D) is dominant over not having dimples (d). A dimpled woman (whose father had no dimples and whose mother did have dimples) marries a man whose mother had no dimples, whose father had no dimples, and whose grandparents on his father’s side did have dimples!

What is the mother's genotype?

A)DD
B)Dd
C)dd

Answers

there both the same so im going to be going for B, B is the correct answer.

The mother's genotype is denoted by Dd. Therefore, option (B) is correct answer.

What kind of trait is dimples?

Hereditary characteristics can be either dominant or recessive, as is the case with humans . Chromosome 5 is thought to be the location of the dominant gene responsible for the inheritance of cheek dimples, while chromosome 16 is thought to be the location of the dominant gene responsible for the inheritance of chin dimples.

It is generally accepted that dimples are caused by a dominant genetic feature, which indicates that the presence of only one mutated copy of a gene in each cell is required to produce the trait. On the other hand, there are academics who argue that there is no evidence to support the theory that dimples are inherited.

ready-to-eat tcs food must be date marked if it will be stored for longer than:

Answers

Given what we know, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours.

What is TCS food?TCS food refers to food that must be stored in temperature-controlled environments to ensure safety.These foods, if not stored properly and at the correct temperatures can cause sickness to the consumers.

Why does it need to be date-marked?The reason the foods need to be date-marked is to relay information to the potential consumer as to by when the food should be consumed. This is done to ensure that if stored correctly, the food does not have time to spoil and cause health risks for consumers.

Therefore, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours in order to protect the health of the consumers.

cell membrane present ribosomes present lysosomes present nuclear membrane present

Animal
Plant
Virus
prokaryote

Answers

Answer:

animal

Explanation:

Animal: All components present. Plant: All components present. Virus: Only cell membrane present. Prokaryote: Cell membrane present, others absent.

Option (1) is correct.

Animal: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Animals are eukaryotic organisms with membrane-bound organelles and a well-defined nucleus.

Plant: Cell membrane, ribosomes, lysosomes, and nuclear membrane are present. Plants are also eukaryotic organisms and share similar cellular structures with animals, including membrane-bound organelles and a nucleus.

Virus: Only a cell membrane may be present, depending on the type of virus. Viruses are acellular particles that lack organelles and a nucleus. They consist of genetic material (DNA or RNA) enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell's membrane.

Prokaryote: Cell membrane is present, but ribosomes, lysosomes, and nuclear membrane are absent. Prokaryotes, such as bacteria, lack a nucleus and membrane-bound organelles. They have a simpler cell structure, with genetic material located in the cytoplasm and ribosomes involved in protein synthesis. Lysosomes, which are membrane-bound organelles involved in digestion, are not present in prokaryotes.

The Statue ofLiberty stands on Liberty Island, near Manhattan in New York. Though she is often thought to beresident of New York, Liberty Island is actually federal property, which means that the Statue ofLiberty belongs to the whole country. The Statue of Liberty is not only the tallest statue in America, itis also one of the most recognizable American symbols.The Statue of Liberty is huge. From the tip of the torch to the pedestal which is the base of the statueon which she stands, she is just over 151 feet tall. If you include the pedestal in your measurement,she stands more than 305 feet off of the ground. Thats more than 30 basketball hoops or an entirefootball field. Her waist size is 35 feet, which would make it awfully tough to find pants, and thetablet she holds is 23 feet long. Dont worry though; she hasnt had any trouble holding that tabletyet with her 8 foot index finger.Though America financed and built the pedestal on which the Statue of Liberty stands, the statueitself was a gift from France. In this way the complete work, much like the United States, is a productof both American and French contributions. At one time America was ruled by the British. Thefounding fathers of America chose to fight against Great Britain for the independence of theircountry. France supported America by providing money, men, and weapons of war. Had it not beenfor French contributions during the Revolutionary War, America would not exist in the way that itdoes today; therefore, it is quite fitting that the Statue of Liberty, which represents freedom, came tobeing by a joint American and French effort. On October 28th, 1886, just over one-hundred yearsafter America declared its independence from Great Britain, the Statue of Liberty was completed anddedicated by its designer, Frdric Auguste Bartholdi.Perhaps no person did more to bring the statue into being than Bartholdi. Not only did Bartholdi gainboth French and American approval for the project, he led the French fundraising efforts anddesigned the appearance of the statue. The appearance of the Statue of Liberty is somewhat resultingfrom Libertas, the Roman goddess of freedom. The torch represents how liberty enlightens the world.The seven points or rays coming from the top of the crown represent the sun, the seven seas, theseven continents, and (as with the torch) how liberty enlightens the world. Though much of thestatue was modeled after depictions of goddesses, Bartholdi modeled the face after his mother. Nowthats a Mothers Day gift thats hard to top.Though Bartholdi was responsible for the external appearance of statute, the internal design can belargely credited to innovative designer, Gustave Eiffel. Though Mr. Eiffel is best known for hiscontributions to a tower in Paris that is named after him, he also engineered the internal structurethat holds up the Statue of Liberty. Eiffel chose to use a flexible structure, so that changes in thetemperature and strong winds from the ocean would not cause the statue to crack. Because of Eiffelscrafty design, the Statue of Liberty may sway as much as three inches on a windy day. If the windsexceed 50 miles per hour, the torch may sway five inches. Eiffel is also responsible for including twospiraling staircases on the interior of the statue to help visitors reach the observation point in thecrown.A.Answer the following questions:1. Why is it significant that the Statue of Liberty is a product of both French and American efforts?2. Eiffel chose to use a flexible structure. Explain.3.
