The enzymatic breakdown of large molecules into their basic building blocks is <u>Mechanical Digestion </u>.
D. Because experimentation includes a control group. also, independent and dependent variables are part of an experiment they arent a type of research
Answer:
The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.
Explanation:
An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.
The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:
- <em>Both dominant alleles: PT
</em>
- <em>One dominant and one recessive allele Pt or pT
</em>
- <em>Both recessive alleles: pt
</em>
Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.
In this set of examples the answer is:
D) The lamprey does not have a vertical column
Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.
