If mass cannot be created or destroyed, what happens when we burn body fat?

1 answer:

When we exercise, we are burning body fat. During exercises, the quantity of body fat cells will start to decrease. As a result, a dominant percentage of the fat molecules are exhaled as carbon dioxide.

do members of the same phylum share more characteristics than members of the same class? Explain why or why not.

SVEN [57.7K]

Answer: No, they don't.

Explanation:

In the taxonomic rank (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species-- in that order) because phylum comes before class, it means it covers a broader spectrum of organisms. So, the traits are less specific. As you narrow it down, the members of the rank will share more and more traits in common.

Here is an example:

Humans are a member of the phylum chordata. All members of phylum chordata share the same 5 traits at some point in their lifetime. (Some only show the traits when they are embryos/larvae). These 5 characteristics share a tail, a notochord, a single, hollow nerve cord, pharyngeal slits, and an endostyle (thyroid).

So, now that we've established that humans are from phylum chordata, we can narrow it down to what class they are in. Humans are in the class mammalia, meaning they are mammals. All mammals not only share those 5 characteristics of phylum chordata, but they also share characteristics that unite them with each other. They all have hair, mammary glands in females, and are endothermic.

So, while members of the phylum chordata share at least 5 traits, members of the class mammalia share at least 8.

I hope that makes sense!

WHY IS IT NECESSARY FOR GAMETES TO BE HAPLOID

olga_2 [115]

Answer:

if gametes were diploid, the number of chromosomes would multiply every generation. To avoid this complexity, gametes posses half the number of chromosomes as somatic cells.

What kind of bond forms when atoms in a molecule do not share their electrons equally

Jet001 [13]

Atoms in a molecule are said to be bonded when they share pairs of electrons with each other and this type of bonding is known as covalent bonding. When they share equal number of electrons in a pair and a full electron shell is completed, they become the most stable. But when the electrons are shared unequally by the atoms in a molecule, a POLAR COVALENT BOND is said to be shared by them. This happens as a result of two atoms sharing electron with different electronegativity i.e. the tendency to attract a shared pair of electrons.
