Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

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:

How are male and female reproductive organs similar?
Answer: They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.

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.

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.

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.
