Answer:

Atoms are the smallest bits of ordinary matter and are made from particles called protons (which carry a positive electrical charge), neutrons (which carry no electrical charge) and electrons (which carry a negative electrical charge).

An element is a substance that is made entirely from one type of atom.

An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best
Nina [5.8K]

Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:<u> vestigial structures</u>.

Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.

  • These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.

  • These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.

  • The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.

Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.

The excretory system helps the respiratory system by
Leto [7]

Answer:

The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).

Explanation:

The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.

As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.

The other options are not correct because:

  • <em>The excretory system does </em><u><em>not introduce more oxygen into the lungs</em></u><em>. </em>
  • <em>The </em><u><em>circulation of blood in and out of the lungs</em></u><em> is a function of the circulatory system. </em>
  • <u><em>Urine is not produced by breathing</em></u><em>.</em>

Why is whitefish used to study mitosis
MakcuM [25]

Answer:

The whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing. ... This is why mitosis is only visible in cells that are dividing, like the whitefish embryo and the onion root tip. Mitosis can take several hours to complete.
