Answer: Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons.
Explanation:
They are called bronchi
Answer:
alveoli
Explanation:
B) Each element in the periodic table has a different number of valence electrons.
C) Valence electrons may be lost or gained by an atom when bonding occurs with another atom
D) When atoms collide with other atoms, they bond automatically
Answer: Option (C) is the correct answer.
Explanation:
Electrons present in the outermost shell of an atom are known as valence electrons.
For example, atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. This means that there are 2 valence electrons in a calcium atom.
These valence electrons can be lost or gained by an atom according to the octet rule and ability to gain stability.
Hence, we can conclude that the statement valence electrons may be lost or gained by an atom when bonding occurs with another atom, is True for valence electrons.
Valence electrons may be lost or gained by an atom when bonding occurs with another atom. The correct option is C.
Valence electrons are the electrons in the outermost energy level, also known as the valence shell, of an atom. These electrons are involved in the bonding behavior of atoms, determining how they interact with other atoms to form chemical compounds.
When atoms come into contact and form chemical bonds, valence electrons can be shared, transferred, or rearranged between the atoms.
This process occurs to achieve a more stable electron configuration for each atom involved.
In some cases, atoms may lose valence electrons to become positively charged ions.
This occurs when an atom has fewer valence electrons than the stable, full outer electron shell configuration. These positively charged ions are called cations.
Thus, the correct option is C.

Answer:
Bull and cow not have udders
Explanation:
Thats
No, there is no breed of male cows that have udders. Udders are mammary glands found in female cows, and their purpose is to produce milk. The udders of female cows are an important reproductive feature that allows them to nourish their young with milk after giving birth.
No, there is no breed of male cows that have udders.
Udders are mammary glands found in female cows, and their purpose is to produce milk. Male cows, also known as bulls, do not have udders because they do not produce milk.
The udders of female cows are an important reproductive feature that allows them to nourish their young with milk after giving birth.

B. Convergent evolution
C. DNA hybridization
D. Natural selection
Answer:
the purpose of testing whether the surface texture of the ground affects the distance an object can roll is to understand how different ground textures impact the movement of objects. By conducting this experiment, we can determine whether objects roll farther or shorter distances depending on the surface they roll on.
