2. Many people moved from their (small farms and rural areas) into cities and earned a living as workers in factories
3. Women started to work in factories, instead of staying at home
Answer:
B- The phenotype of the progeny reveal the allelic content of the gamete from the heterozygous parent.
Explanation:
Normally, such tests are used to identify the allele content of the parent, to determine the gene dominance and recessiveness. That is, which gene is dominant ,and which is recessive. These would enable easier mapping of traits of newly found species.
The correct answer is by composition and texture. Composition is that minerals that the rock are made of. Texture refers to the grain size of the different components of that rock. Texture has to do with sizes of mineral grains and other constituents in a rock and how the sizes and shapes relate to each other.
Answer:
0
Explanation:
This question involves two genes; A and B. According to the question, two parents are crossed as follows: AABB × Aabb. The parents will produce the following gametes:
AABB- AB, AB, AB, AB
Aabb - Ab, Ab, ab, ab
Using these gametes in a punnet square (see attached image), the offsprings in the following proportion will be produced:
AABb = 4/16 = 1/4
AaBb = 4/16 = 1/4
Therefore, none (0) of the offsprings will resemble the phenotype of the second parent (Aabb).
Answer:
Concentration gradient.
Explanation:
Diffusion may be defined as the process of the movement of solute particles down the concentration gradient. This process does not require the expenditure of energy.
The main driving force in diffusion is the concentration gradient. The molecules generally move from its region of the higher concentration towards the region its lower concentration.
Thus, the correct answer is option (3).
