Answer: True

Explanation:

Asteres planetoid, or 'wandering stars,' was the term used by Greek astronomers to describe star-like objects that appeared to move across the sky.

The term has been applied to a wide range of objects, including the moon, satellites, the sun, and asteroids.

A planet, according to the International Astronomical Union (IAU), is a body that orbits the Sun, is massive enough for its own gravity to keep it around, and has 'cleared its neighborhood' of smaller objects approaching its orbit.

I suppose the last option to be correct.

Explanation:

I hope this helps you :)

Answer:

Your answer is b

Explanation:

the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.

The statement that supports the fact that phytoplankton are one of the most important parts of the food web in the Hudson river is; "the decrease in phytoplankton caused a decrease in the river's zooplankton, fish, and native mussel populations."

Phytoplankton refers to the microscopic and photosynthetic organisms found in water bodies. They are able to trap energy directly from the sun to produce their own food by photosynthesis.

If this primary productivity is hampered in the food web in the Hudson river, there will be nothing for the small fishes to and other native populations to eat and their population will begin to decrease.

The period of time when sexual intercourse takes place between two organisms is called mating. However, all the matings need not end in fertilization.

The gestation period is a time when the embryo develops completely into a fetus. This is usually from the time of fertilization to the time of giving birth.

Let us take the comparison of the gestation period of 3 mammals.

The gestation period of a cow varies from 279- 287 days. The mating between the bull and cow occurs during the heat or oestrus period of the cow. At that time the bull mounts on the cow or vice-versa may happen during the mating period. This is termed bulling.

In the case of horses, the gestation period is 320-380days. The mating ritual in a horse is a bit different than in a cow. It usually has three phases of sexual behavior which includes: courtship, mating, and post mating behavior. During courtship, the stallion which is the male horse will approach the mare, prance, sniff her, nuzzle her, and groom her. The mare which is the female horse may squeal, kick, or move away to show the stallion that she is not ready. When the mare is receptive to breeding, she may stand still, deviate her tail, and urinate, leading the stallion to mount her. It usually breeds well in pastures than in controlled environmental breeding conditions.

Whereas in camels, the gestation period is far longer than in cows and horses. It is about 360-440days. The male camel displays its organ called a dulla to show out is ready for mating. The male camel Urinates on its own tail and swishes it over its back so that the Urine contains female-attracting pheromones. It shows distinct violent behavior towards other male camels. The female camel undergoes an estrous cycle in the breeding season which lasts receptive for 3-4 days, and non-receptive following the other 10 days. In the receptive period, the camel sits down and exposes its genitalia for the male camel to copulate. The whole mating takes about 20 minutes and is accompanied by gurgling and frothing by the male and bleating by the females.

It should be noted that African elephants have longer gestation periods like Asian elephants whereas no other animal has a longer gestation period than an elephant or a shorter gestation period than mice.

Answer:

Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds

Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.

Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.

Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.

The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.

Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.

Explanation:

Answer:

...

Explanation:

find density of salt solution 585g/500cc = 1.17g/cc

leaves density = 1.25g/cc, stars density = 1.12g/cc

Stars float, leaves sink. since everything is in g/cc, you do not have to worry about the info 1ml=1cc.

density = mass / volume.

density of salt solution = 585g(mass)/500cc(volume)

Answer:

pls mark as brainliest!!!!!!

Explanation:

If you considering in smaller scale You can simply say that “There is One Hydrogen atom Binds with Cl atom”. But when we are using this chemicals in Labs.

We talking in Moles

Mole is a quantity defining unit. Which is larger than you couldn't Imagine. 1 mole of pebbles can covered whole surface of earth.

1Mole=6.022×1023

It means 1 mole of Hydrogen is containing 6.022×1023 atoms. Be aware “Be aware thats a Quantity defining factor” Then we can get actual ratio of chemical formula..

HCL “The chemical formula”

H : 1 “Above chemical formula containing 1 atom to binds with another species”

Cl : 1 “Clorin also same as Hydrogen”

Then, You can multiply Ratio of atom by Avagadro Constant which is we pre defined as 1 Mole.

For understand it simply This statement would be helpful.

1 mole containing, Avagadro number of atoms

Hope This would be helpful!

Answer:

the answer is going to be 3 because it asked how many atoms of hydrogen it never said how many number of atoms of hydrogen.

so,

     HCl has 1 atom of hydrogen in ONE MOLE but there are 3 moles given so you multiply the atoms of hydrogen by 3 that is going to be your answer i.e. 3

Answer:

An atom is the basic particle from which all elements are made. Different elements have different properties because their atoms are different.

A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements/ratio of atoms.

The chemical formula is a representation of a compound, molecule, substance in types and numbers of atoms that repeat to make up a substance. 

Compounds can be in forms of: empirical, molecular, or structural formulas. 

For example, part of the gas you inhale is carbon dioxide. Its chemical formula is CO2. The number 2 below the symbol for oxygen tells you that the ratio of carbon dioxide is 1 to 2. 

If a different ratio of carbon atoms and oxygen atoms are seen in a formula, you have a different compound.

So the number and type of atoms in a chemical affect their properties.
