of disease transmission most likely spread the infection from the deer mice to Derek?

If B represents the allele for black eyes (dominant) and b represents the allele for orange eyes (recessive), what would be the
Nuetrik [128]

Answer:

1 black : 1 orange

Explanation:

This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.

In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.

This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structu
hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living.  - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells.  - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
