Describe the structural organization shared by the cilia and flagella?

1 answer:

8 0

Both flagella and cilia have a common structural arrangement of microtubules referred to as "9 + 2 array." A single cilium or flagellum is made up of string of nine microtubule doublets that surround a single microtubule doublet in the center.

Flagella are hair-like structures which are usually long and they extend from the plasma membrane. They are used to propel or move an entire cell, for example sperm cell.

Cilia are short hair-like structures that are used to move entire cells. An example is paramecia. Cilia can also be found lining the outer surface of cells such as those of the respiratory tract where they move trapped particles up toward the nose and mouth.

Why is frog egg laid in long gelatin fluid

Naya [18.7K]

Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.

Is it true that the Earth’s climate systems are driven by the electromagnetic radition from the sun, as well as its reflection,

nordsb [41]

Totally. Earth's climate systems are driven by the electromagnetic radiation that comes from the Sun. The incoming radiation that comes from the Sun is reflected by the clouds, passes through Earth's surface, or is even absorbed by the planet's atmosphere. The atmosphere warms thanks to the chemical reactions of larger aerosol particles in the atmosphere absorbing this radiation.

A chemical reaction is shown.

mixas84 [53]

Answer:

1) A chemical reaction is shown.

SnO2 + H2 → Sn + H2O

What is true about this chemical reaction?

It is unbalanced because the mass of the reactants (number of atoms) is greater than the mass of the products (number of atoms).

2) Read the information about an experiment.

Jadon plans on carrying out an experiment involving the burning of steel wool to illustrate the conservation of mass. Steel wool is made of iron. When it is burned it combines with oxygen to form iron(III) oxide.

Which step in his experiment is the most important if he wants his experiment to correctly demonstrate the conservation of mass?

The steel wool should be burned inside of a sealed jar or other closed system.
