Explanation:
Answer;
-Adhesion
Explanation;
-Adhesion is the attraction between water and other molecules.
Adhesion and cohesion are water properties that affect every water molecule on earth and also the interaction of water molecules with molecules of other substances.
-Adhesion is observed when water moves up the tube placed in a glass of water: the water appears to be higher on the sides of the tube than in the middle. This is because the water molecules are attracted to the charged glass walls of the capillary more than they are to each other and therefore adhere to it. This type of adhesion is called capillary action.
-Cohesive and adhesive forces are important for the transport of water from the roots to the leaves in plants.
Answer:It would be most likely in between
Explanation:
According to Mendel's law of dominance , when two alternative alleles of a trait are present together, one of these is able to dominate over the other and expresses itself in phenotype. This allele is termed dominant allele. The other allele, though present is not able to express itself, is termed recessive allele .
Answer:
33
Explanation:
because proton number is always equal to atomic number
Asexual reproduction
Sexual reproduction
Explanation:
In asexual reproduction the offspring are genetically identical to the parents. Asexual reproduction include binary fission, fragmentation and vegetative propagation.
It involves direct inheritance of the genetic copy of the parent without any alteration. The parent gives rise to the offspring without any intermediary process.
In binary fission, the parent simply divides into two to form a new ones.
For sexual reproduction, there is fusion of gametes which carries genetic materials contributed by both parents. The offspring is an offshoot of the genetic combination of the traits of two parents.
Therefore, genetically, offspring produced by sexual reproduction have a distinct copy of the genotypes they posses. They are different from those of the parents.
