F. They can catalyze the same reaction repeatedly.

Answers

Answer:

They are necessary for a chemical reaction to occur

They increase the efficiency of chemical reactions

Enzymes are proteins that act as biological catalysts by speeding up chemical reactions. Substrates are molecules with which enzymes can interact, and enzymes convert substrates into other molecules known as products.

What is enzymes? Biochemical reactions are sped up by enzymes, which operate as biological catalysts. The most popular explanation proposes that enzymes bind to the substrate molecule and create a transition state. An energy barrier that the substrates must pass separates the products from the substrates as the reaction progresses.Digressionary enzymes are produced by your pancreas, small intestine, and stomach. The "powerhouse" of digestion's enzymes is actually the pancreas. The most crucial digestive enzymes that break down proteins, carbs, and fats are produced by it.

A person with type A blood (unknown genotype) marries a person with type O blood. What blood types are possible among their children. (Show 2 crosses)

Answers

Answer:

If a person with blood type A, of unknown genotype, and a person with blood type O have offspring, the only possible blood types in children are A and O.

Explanation:

It should be noted that in the case of blood type A, the possible genotypes are A|A or A|O, while blood type O (recessive) will always have genotype O|O.  Assuming that it is the father who has the blood group A:

♂ A|A or A|O

♀ O|O

- Cross 1: If the father possesses the dominant A characteristic on both alleles

Alleles     A         A

O           A|O      A|O

O          A|O       A|O

In this case all the offspring will have a blood type A, with a heterozygous genotype.

- Cross 2: If the father has blood type A, but with a heterozygous genotype

Alleles     A         O

O            A|O     O|O

O            A|O     O|O

50% of the descendants will be of blood type A, heterozygous

The other 50% will be blood type O.

Blood type is determined by the presence or absence of surface antigens A and B.

Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, and genotype O|O .

Thus, depending on the genotype of one of the parents A|A or A|O, when crossed with a parent type O O|O, their children may have blood type A or O.

Please explain in your own words how a nebula forms into a star, using the terms: Mass, Gravity, Pressure, Temperature, Nuclear Fusion.

Answers

Once massive stars reach the red giant phase, the core temperature continues to increase as carbon atoms are formed from the fusion of helium atoms. Gravity continues to pull together the carbon atoms in the core until the temperature reaches 600,000,000 degrees Celsius. At this temperature, carbon atoms form heavy elements such as oxygen and nitrogen. The fusion and production of heavy elements continues until iron starts to form. At this point, fusion stops and the iron atoms start to absorb energy. This energy is eventually released in a powerful explosion called a supernova. A supernova can light the sky up for weeks. The temperature in a supernova can reach 1,000,000,000 degrees Celsius. This high temperature can lead to the production of new elements which may appear in the new nebula that results after the supernova explosion. The core of a massive star that is 1.5 to 4 times as massive as our Sun ends up as a neutron star after the supernova. Neutron stars spin rapidly giving off radio waves. If the radio waves appear to be emitted in pulses (due to the star's spin), these neutron stars are called pulsars. The core of a massive star that has 10 or more times the mass of our Sun remains massive after the supernova. No nuclear fusion is taking place to support the core, so it is swallowed by its own gravity. It has now become a black hole which readily swallows any matter and energy that comes too near it. Some black holes have companion stars whose gases they pull off. As the gases are pulled down into the black hole, they heat up and give off energy in the form of X-rays. Black holes are detected by the X-rays which are given off as matter falls down into the hole.

How do waterfalls form? A meander gets cut off. Sediment builds up. Soft rock erodes. Flat areas flood.

Answers

Answer:

The correct answer is "soft rock erodes."

Explanation:

Waterfalls form as streams flow from soft rock to hard rock. This happens as a stream flows across the earth and as the stream drops in a waterfall. In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.

As streams go from soft rock to hard rock, waterfalls are created. This occurs as a stream travels across the surface of the ground and as it descends in a cascade.

What is waterfall?

The first Process Model to be introduced was the Waterfall Model. The term "linear-sequential life cycle model" is also used to describe it.  There is no overlap between phases in a waterfall model; each step must be finished before the subsequent phase can start.

The first SDLC methodology for software development was the waterfall model.

The software development process is depicted using the waterfall model, which follows a linear sequential flow. This implies that a phase of development can only start if the one before it is finished.

Therefore, As streams go from soft rock to hard rock, waterfalls are created. This occurs as a stream travels across the surface of the ground and as it descends in a cascade.

Answers

Answer:

Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body. Although gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms.

Transport of Oxygen in the Blood

Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.

Hemoglobin

Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 20.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.

Can diffuse? YES or NO
Molecule
Glucose
Starch
Protein
Iodine
Water
Salt

Answers

Answer: Molecule: Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.

Glucose:Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.

Starch: Starch does not pass through the synthetic selectively permeable membrane because starch molecules are too large to fit through the pores of the dialysis tubing. ... Diffusion results from the random motion of molecules. Diffusion moves substances from regions of higher concentration to regions of lower concentration.

Protein: Can all membrane proteins diffuse freely around the membrane? Many, but not all membrane proteins can diffuse laterally through the lipid bilayer. Some proteins cannot do this because of their attachment, either to other proteins or to the underlying cytoskeletal filaments.

Iodine: The Dialysis tubing provides a semi-permeable membrane. Only allowing smaller molecules to pass through it. Iodine molecules are small enough to pass freely through the membrane, however starch molecules are complex and too large to pass through the membrane. ... Thus iodine diffused into the tube with the starch.

Water: Water also diffuses away from areas of high free water concentration into areas of more solute concentration. ... Thus, only water can diffuse. This diffusion of water across a semi-permeable membrane is called osmosis.

Salt: In turns out when salts are exposed to water, they dissolve into charge atoms (called ions). These atoms are very tiny and mobile and can easily diffuse from the surface past the meat molecules, given enough time.

Explanation:

Multicellular creatures use a variety of cells to perform their many duties, in contrast to unicellular organisms, which consist of just one cell that performs all the processes required by the organism.

What is unicellular and multicellular in eukaryotes?

In a unicellular creature, a single cell manages the life process. A multicellular organism's numerous cells are each specialized to perform certain functions.

Eukaryotes and prokaryotes are both examples of unicellular creatures. However, only eukaryotes are classified as multicellular organisms.  Because of this, these cells are often larger than prokaryote cells.

Eukaryotes do contain cell nuclei, and they have more intricate structures. A few examples of unicellular eukaryotes are yeast and algae. Eukaryotic cells, in contrast to prokaryotes, have organelles, which serve crucial roles inside the cell.

Each colony now had productive farms and new towns growing as trading posts. Britain profited from these by taxation. Everything grown, bought or sold in the American Colonies was somehow taxed by Britain.Another effect was the British Colonies became destinations for thousands of immigrants from England and elsewhere in Europe. Wealthy Europeans were eager to claim new land for plantations or make fortunes from trade in the new cities. Middle-class European farmers hoped they could get new farmland of their own. Many poor English and Scots-Irish settlers hoped they could find better lives in America working as indentured servants and hopefully purchasing land of their own someday.Every new English colony was a new disaster for the Native Americans. The forests they hunted were cut down to make way for farms and plantations. More and more tribes became pushed off their land, either being cheated by false negotiations, or forced out with violence. When tribes fought back, the English settlers would retaliate harshly with gunfire and arson, burning entire villages to the ground. Worse still was the invisible killer that British settlers brought with them: diseases like smallpox and plague, which spread among native tribes quickly and for which they had no immunity or treatments. Sometimes, colonists would give infected blankets to natives to spread diseases on purpose. Ultimately for the native tribes, the effects of British settlement in America were tragic and irreversible. By the mid 1700s, most tribes had nearly vanished from the Atlantic coast.The final effect of the British Colonies was the introduction of slavery to North America. The first kidnapped Africans in the American Colonies were brought to Jamestown as slaves to work in the new tobacco plantations. Slavery would spread throughout the new colonies, with cities as far north as New York being used as trading posts for slave auctions. Mainly however, slavery was much more concentrated in the southern colonies, which had large tobacco and rice plantations requiring many laborers. In the Southern Colonies, African people were simply considered property. Laws in Maryland only referred to Africans in terms of planters property rights. A Virginia law in 1642 punished people for hiding runaway slaves or indentured servants. Free blacks were eventually permitted to live and own property in northern colonies, and slavery in the north slowly became outlawed. In the south, however, the plantation economies of the colonies depended almost completely on slave labor.17.
