Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose f

Anettt [7]

Answer:

Man: Bb

Man’s mother: bb

Woman:Bb

Woman’s father: bb

Explanation:

Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.

Animal and Plant Cell Organelles Use the drop-down menus to determine where these organelles can be found. Ribosome Endoplasmic

rjkz [21]

Answer:

Animal Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, small Vacuoles, Lysosomes, Mitochondria, Cell membrane, Cytoplasm.

Plant Cell:

Ribosome, Endoplasmic reticulum, Golgi apparatus, Cell wall, Big Vacuole, Lysosomes, Mitochondria, Cell membrane, Cytoplasm, Chloroplasts.

Explanation:

 Animal Cells Vegetable Cells

Cell wall NO YES

Vacuoles YES, Small and more than ones YES, Only one and big

Chloroplast NO YES

Plasmatic membrane YES YES

Mitochondria YES YES

Lysosomes YES YES

Endoplasmic reticulum YES YES

Golgi apparatus YES YES

Cytoplasm YES YES

Ribosome YES YES

Both the animal and plant cells are eukaryotic. They carry their genetic material in the nucleus and mitochondria. Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.

However, they have some differences:

Cell wall: A rigid structure that provides support and protection.

Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible, so they can adopt different shapes.
Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

Chloroplast: these are organelles that accumulate chlorophyll.

Animal cells do not have chloroplasts because they do not photosynthesize.
Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

Vacuoles:

Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.

Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

Other differences are:

The animal cell has centrioles, while the vegetable cell does not.

Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.
