Cell tracking shows that axolotl cells in a regrowing leg retain distinct roles. ... Salamanders have the ability to regrow amputated limbs. These cells then divide and differentiate into the tissue types needed. The adult tissues are reprogrammed to make these blastema stem cells
The mitosis or the mitochondria
Molecular-level structure is vital in the design and use of materials mostly at the macroscopic-stage. The structure of a molecule is known to influence how it interacts with other molecules.
Note that Attractive and repulsive forces are the ones that plays a vital role in the total properties of matter seen on the scale.
Molecular structure is known to be the one that helps us to know more about Nature's intricate design methods and blueprints. When we know the blueprints and basic materials, we can then try to mimic her essential products that are cost effective and the ones that has less harmful environmental effects.
<h3>What is the Difference between bonding forces and intermolecular forces ?</h3>
The Difference between bonding forces and intermolecular forces is that Intermolecular forces are known to be forces that are said to hold two or more molecules as one while a chemical bond is known to be an attractive force that exist between two or more atoms.
The types of chemical bonding and intermolecular forces that materials have are:
For Chemical bonds they are:
- Covalent
- Polar covalent
- Ionic bonds
For Intermolecular forces, the three types are van der Waals forces are:
- Dispersion forces.
- Permanent dipole-dipole forces.
- Hydrogen bonding.

Answer:
a) BB
b) bb
c) Bb
Explanation:
Co-dominance is a type of non-mendelian genetic inheritance in which two alleles of a gene are neither dominant nor recessive over one another, hence, they form an hybrid offspring that simultaneously exhibits the traits encoded by both alleles. This is the case of the scale color gene in a certain fish. The allele for blue scales (B) and allele for red scales are codominant. Hence, they produce an hybrid with a patchwork of both blue and red colours.
Therefore, a fish with blue scale color will possess an homozygous genotype of the blue allele: BB while a fish with a red scale color will possess an homozygous genotype of the red allele: bb. Since the patchwork fish is an hybrid or heterozygous, it will contain a combination of the blue and red alleles i.e. Bb.
Because both alleles (red and blue) are codominant, both traits encoded by both alleles will be expressed at the same time in the hybrid organism (patchwork fish).
The correction option is A.
Reproductive isolation is divided into two major classes, which are prezygotic and postzygotic isolation. Prezygotic isolation refers to the barriers that are present before the egg can be fertilized while postzygotic isolation refers to those barriers that are present after the egg has been fertilized. Mechanical isolation is a type of prezygotic isolation. Mechanical isolation is a type of reproductive barrier which exist because the male and the female genitalia have different sizes, shapes and locations. The snails that coil to the left and those that coil to the right have the locations of their genitalia in different places.
