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

houses nasal conchae to enhance turbulence for filtering air
Answer:
Houses nasal conchae to enhance turbulence for filtering air. larynx. Prevents food and liquid from entering the rest of the respiratory tract.
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.

One property of a senescent cell is that it can no longer divide.
Senescent cells are cells which help in tissue development in an embryo and also helps to promote healing of injuries.
These cells however exhibit a very a large lysosomal activity which destroys
vital components in the molecules . This thereby prevents the senescent
cells from not being able to divide.

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:

Explanation:
Grouper or a type of fish that often wait until they are around 20 years old to reproduce based on this group or could be considered
The type of fish or Grouper which reproduce when they are around 20 years old is called monandric protogynous hermaphrodites.
The Groupers is a type of fish that is characterized by a large mouth and stout body.
They belong to the subfamily of Epinephelinae.
These groupers are known as monandric protogynous hermaphrodites because they mature to become only females which changes their sexes after sexual maturity.
This change in sex of the fish depends on internal or external triggers.
These reproductive changes usually occurs around 20 years of age in a groupers.
Therefore, the type of fish or Grouper which reproduce when they are around 20 years old is called monandric protogynous hermaphrodites.

Explanation:

brainly plz
Answer:
hehe i just finished answer a question about pollution sooo here you go :) this is just an example and not a full essay I recommend adding more evidence!! (please write in your own words)
Pollution has been a problem for over 2,000 years now. There are many things that are causing pollution. For example firecrackers!
Using firecrackers can be very dangerous not just for us, but the environment as well. Firing crackers can increase the concentration of dust and pollutants in the air. After firing, the fine dust particles settle on the surrounding surfaces which are packed with chemicals like copper, zinc, sodium, and lead. Now you may think oh so it's bad for the air so what? If the air is polluted, trees and plants that give us oxygen can't do their job. If they can't do their job we can't breathe or live. Most of the chemicals that are bad for the air are in firecrackers. These chemicals can last for hours or days on end, exposing you and your neighbors to possible long-term health problems. Then fireworks also have the potential of starting wildfires. About 7,500 to 10,600 trees were burnt down (10% to 14% of trees) in California alone due to wildfires. About 19,500 trees were burnt down just from fireworks.
give example on substitutions for frieworks. I would recommend adding more information about how the chemicals in the firecrackers are dangerous for the air. Since I didn't go into full enough details (if you don't you might get marked down for not having enough details or evidence)

What are centrioles and centrosomes?
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.
