Explanation:

Houses nasal conchae to enhance turbulence for filtering air through nasal cavity. Hence, the correct option is A.

What is nasal cavity?

It is a large air filled space within the nose and is part of the respiratory system. It is lined by an inner thin layer of moist mucous membrane which helps to humidify and filter the air as it is breathed in.

The nasal cavity is divided into two parts-the right and left nasal cavities, separated by a thin bony wall called septum. It is involved in the sense of smell, as small receptors located in the mucous membrane of the nasal cavity are responsible for detecting different odors.

Overall, the nasal cavity is a crucial part of the respiratory system and plays an important role in protecting the body from inhaled irritants, facilitating the sense of smell. Hence, the correct option is A.

What are centrioles and centrosomes?​

Answers

Answer:

What are centrioles and centrosome?

Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm

Explanation:

Answer:

a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.

Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

the electron transport chain consists of a series of membrane-bound carriers that shuttle protons and electrons to nadh. true or false?

Answers

Answer:

ture

Explanation:

The statement "the electron transport chain consists of a series of membrane-bound carriers that shuttle protons and electrons to NADH" is absolutely false.

What is the Electron transport chain?

The electron transport chain may be defined as a sequence of four protein complexes that significantly perform a couple of redox reactions in order to construct an electrochemical gradient that directs to the formation of ATP in an overall system that is named as oxidative phosphorylation.

The electron transport chain typically includes the series of electron transporters that are generally embedded in the inner membrane of mitochondria in order to shuttle down the electrons only from NADH and FADH2 to molecular oxygen.

While the given statement reveals that electrons and protons both shuttle to NADH but FADH2 is also involved.

Therefore, the statement which is given about the electron transport chain is definitely false.

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable

Pluto's surface is made mostly of frozen nitrogen..Pluto's orbit is slowing down due to tidal friction.What is Falsifiable and Non-falsifiable hypotheses?

Falsifiability is the capability for some proposition, statement, theory or hypothesis to be confirmed wrong. That capacity exists as an important component of the scientific approach and hypothesis testing. In a scientific context, falsifiability exists sometimes regarded synonymous with testability.

The falsifiable hypothesis can be denied by tests done with the most delinquent technology. The non-falsifiable hypotheses on the other hand can't refuted as tests have confirmed them to be true.

Hence,

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable
