Can someone describe major subatomic particles that make up an atom

1 answer:

7 0

The main 3 subatomic particles that makes up an atom are protons, neutrons, and electrons.

Protons and neutrons exists inside the nucleus of the atom, while electrons moves freely outside the nucleus.

Protons are positive in charge, each element has their own specific number of protons, it's just like their ID number for the element, they cannot be changed.

Neutrons are neutral, just like as it name says. Usually they have the same number as the protons in most elements, but not all cases. Sometimes an element may even have a few different forms, called Isotopes specifically, where they have different number of protons for each isotope.

And electrons, are negative in charge. They're a lot more lighter comparing to neutrons and protons, therefore sometimes we neglect their mass in calculating maths. In an atom, the number of electrons must be the same as the number of protons, or else, the atom would no longer be an atom, but an ion instead.

Rebekah is studying a molecule and trying to determine if it is DNA or RNA. Which kind of molecule is she studying? I NEED HELP

Alex

Answer: Rebekah is studying [C-nucleic acids].

Explanation: This is since both DNA (DeoxyriboNucleic Acid) and RNA (RiboNucleic Acid) contain nucleic acids, as their names show.

All of the following describe possible results of competition between two species except A) competitive exclusion. B) aposematic

boyakko [2]

Answer:

B) aposematic coloration

Explanation:

The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.

Mediated transport of polar molecules and ions across the plasma membrane utilizes a(n) _____ carrier that binds to the substanc

agasfer [191]

The question is incomplete as it does not have the options which are:

Protein carrier

Lipid carrier

Porin carrier

All of the choices are correct

Answer:

Protein carrier

Explanation:

The transport of molecules through diffusion can be passive or facilitated. The facilitated diffusion in which the molecules are facilitated to cross required tow type of protein channels which are the channel proteins and the carrier proteins.

The carrier proteins are the transmembrane proteins which are specific for ions and to transport the molecules change their shape of conformation. The change in the shape is responsible for the release of ions on the other side of the membrane.

Thus, Protein carrier is correct.
