Answer:

1 A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus.

2 Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.

3 Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

4 The plasma membrane.

Cytoplasm.

Ribosomes.

Genetic material (DNA and RNA)

5 Prokaryotes

mestny [16]

The correct answer is Includes the Golgi apparatus and the endoplasmic reticulum.

The endomembrane systemrepresents a group of membranes and organelles that works together to modify, package, and transport lipids and proteins. It exists in eukaryotic cells only. The endomembrane system does not include all the organelles, like mitochondria, chloroplasts, or peroxisomes.

Examine a two-gene cross that follows simple Mendelian inheritance of freckles and eyebrow shape between a woman with genotype M

Brilliant_brown [7]

Answer:

Explanation:

First, let us look at the result of crossing the two genotypes Mmpp and mmpp.

Mmpp will give the gametes Mp, Mp, mp, and mp

mmpp will give the gametes mp, mp, mp, and mp

The two sets of gametes can thus be lined up on both axis of the Punnet's square as shown in the attached image.

Genotypes of the offspring: 8 Mmpp and 8 mmpp

<u>Since the two genes follow simple Mendelian inheritance pattern, the 2 genotypes automatically equates to 2 phenotypes in the ratio 1:1.</u>

<em>Hence, the correct option is </em><em>b</em><em>.</em>

The Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).

<h3>What is a Punnett square?</h3>

A Punnett square is a diagram used in genetics to calculate the genotypic proportion from a given genetic cross.

Two different genes may generate 16 genetic (allelic) combinations in a Punnett square.

Moreover, fur color and eye color are phenotypic traits that depend on the recessive-dominance allele relationships received in offspring.

In conclusion, the Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).
