Answer: Wrist
Explanation: The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones. This arrangement of bones allows for a wide range of movement.
Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.
Explanation:
The 9:3:3:1 ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.
Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.
Answer:
25%
Explanation:
So there are 4 recessive alleles present for black fur on the square and there are also 4 dominant alleles. As there are the same amount of dominants as recessives the dominants will take over and be in control so the recessive alleles won't have as much of a chance
Answer:
- Label A - G1 phase
- Label B - S phase
- Label C
- G2 phase
- Label D - Mitosis
- Label E - interphase
Explanation:
Label A - G1 phase (First gap phase): during this phase, cell grows, forms more protein, RNA and copies cell organelles.
Label B- S phase (Synthesis phase): during this phase, synthesis of DNA and its replication occurs.
Label C- G2 phase (Second Gap phase): during this phase the cell grows more, makes protein and cell organelles.
Label D – Mitosis: during mitosis the cell divides its nucleus and cytoplasm to produce two daughter cells.
Label E- Interphase : A stage of cell growth and metabolic activity. The G1,S and G2 phases together called interphase.
For a chemical reaction to occur, activation energy is required. Using the activation energy, reactants form products by breaking bonds which require energy. This type of reaction is an endothermic reaction. When products are formed, bonds are formed back by releasing energy. This type of reaction is an exothermic reaction. When activation energy is used for a reaction, a catalyst is not required. Adding a catalyst to the reaction causes the rate of reaction to increase.
