Biology questions. some are select all that apply but some might not have multiple choices

The answers are:

4. The streamlined body shape of a dolphin and a shark. (assume no recent common ancestor with trait).

6. Organisms of different domains

7. Made up of tissues

Explanation:

4.

Analogous Structures:

Analogous structures are organs or structural (morphological or anatomical) features that perform similar functions but do not possess the same evolutionary and ancestral origin.

6.

The three principal domains of life are:

These domains possess fundamental differences in the form of genetic material and cellular characterization (unicellular/multicellular). This is the broadest system of classification. The  others, kingdom, phylum, order, genus, species are further classification of the 3 major domains.

7.

The first and fundamental postulate of the cell theory,  the basic theory of biology is:

All livings things are made up of cells.

Cells further combine to form tissues. Therefore, any organism that is composed of cells and tissues is living.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!

explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
