What does it mean to say B is representing the dominant gene
Degger [83]

Answer:

Dominant genes are always represented by a capital letter which in this case is the letter B whereas recessive genes will be represented by a lower case letter like b.

You only need one copy of a dominant gene or allele to inherit it. A dominant allele is always expressed even if only one copy is present.

But you need two copies of genes or alleles to inherit the recessive gene. There also can't be a dominant allele of the gene if you are to inherit this.

Allele - Different forms of a gene

6. According to the ideas of Democritus and Dalton, which of the following
Varvara68 [4.7K]

Answer: The wire is still copper and does not change by cutting it

Explanation:

Democritus postulated that all materials were composed of these tiny particles called as "atomos".

Daltons postulates are:.

1. All matter is made of very tiny particles called atoms.

2. Atoms is indivisible.

3. Atoms of a given element are identical in mass and chemical properties.

4. Atoms of different elements have different masses and chemical properties.

5. Atoms combine in the ratio of small whole numbers to form compounds.

6. The relative number and kinds of atoms are constant in a given compound.

Thus when copper wire is cut into the smallest  possible pieces, the atoms were intact as they are indivisible and all atoms have same mass and chemical properties.Thus the wire is still copper and does not change by cutting it

3 The volume of a gas is 50.0 mL at 20.0 K. What will be the new
Damm [24]

Answer:

C. 4.00 K

Explanation:

We can solve this using Charles's Law of the ideal gas. The law describes that when the pressure is constant, the volume will be directly proportional to the temperature. Note that the temperature here should only use the Kelvin unit. Before compressed, the volume of the gas is 50ml(V1) and the temperature is 20K (T1). After compressed the volume becomes 10ml(V2). The calculation will be:

V1 / T1= V2 / T2

50ml / 20K = 10ml / T2

T2= 10ml/ 50ml * 20K

T2= 4K

Which of the following explains how Hahn, Strassman, and Meitner tried to
attashe74 [19]

Answer is: A. They opposed the use of energy released during nuclear fission for military purposes.

Hahn, Strassmann and Meitner were not engaged in nuclear weapons research during World War II.

Otto Hahn (1879 - 1968) became a passionate campaigner against the use of nuclear energy as a weapon.

Hahn and Strassmann discovered nuclear fission (nuclear fission of uranium in 1939).
