Answer:

11. I think the answer is, Both humans and whale embryos have a tail and a backbone (I'm not sure).

12. Basilosaurid, any member of the family Basilosauridae, an early group of whales that lived from the middle Eocene to the late Oligocene Epoch (about 41 million to 23 million years ago).

13.  Protocetids had long snouts, large eyes, and their nasal opening was farther caudally than in earlier archaeocetes.

Hope this helps! :D

Are frosted flakes healthier than fruit loops?
Komok [63]

Answer:

The answer is below!!

Explanation:

Although Frosted Flakes are higher in sugar than other cereals and often not considered diet food, they can be part of a healthy weight-loss plan. Cereals that are low in calories and fat content such as Frosted Flakes may help you lose weight.

“Froot Loops is an excellent source of many essential vitamins and minerals and it is also a good source of fiber with only 12 grams of sugar,” said Celeste A. Clark, senior vice president of global nutrition for Kellogg's, which makes Froot Loops.

Hope I Helped!!

When two monosaccharides condense to form a disaccharide, what is the other product of the reaction? enter the molecular formula
koban [17]

When two monosaccharides combine to make a disaccharide, water is the byproduct.

<h3>What are monosaccharides ?</h3>

The most fundamental building blocks from which all carbohydrates are constructed are monosaccharides, commonly known as simple sugars. They are the most basic types of sugar. They are typically crystalline solids, colorless, and soluble in water.

These three monosaccharides—glucose, fructose, and galactose—are crucial for nutrition. Six carbon atoms, twelve hydrogen atoms, and six oxygen atoms make up each single sugar molecule.

Which of these electron transitions correspond to absorption of energy and which to emission?
Elan Coil [88]

Answer:

n = 5 to n = 6 absorption

n = 9 to n = 6 emission

n = 6 to n = 4 emission

n = 6 to n = 7 absorption

Explanation:

According to the Bohr's model of the atom. An electron in an atom may absorb energy and move from a lower energy level to a higher energy level. This requires absorption of energy that is equal to the energy difference between the two levels.

Similarly, an electron may move from a higher to a lower energy level, releasing energy that is equal to the energy difference between the higher and the lower level. This is known as emission.

Hence, if the electron is moving from a lower energy level to a higher energy level, an absorption has taken place, e.g n = 5 to n = 6

When an electron moves from a higher energy level to a lower energy level, an emission has taken place e.g n = 9 to n = 6

What pressure, in torr, would a sample of Xenon exert if it were compressed from 4001 mL to 3002 mL at constant temperature, giv
Andreyy89

Answer:

759779.6 torr

Explanation:

Initial volume, V₁ = 4001 mL

Final volume, V₂ = 3002 mL

Initial pressure, P₁ = 750.1 atm

We need to find the final pressure at a constant temperature. Let it be P₂. P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{750.1\times 4001 }{3002 }\\\\P_2=999.71\ atm

We know that,

1 atm = 760 torr

So,

999.71 atm = 759779.6 torr

Hence, there will be 759779.6 torr pressure.
