If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?
kaheart [24]

Answer:

only females

Explanation:

In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.

Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).

N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.

Match each organelle with the correct function.
Arturiano [62]

Answer:

Explanation:

EUKARYOTIC CELL STRUCTURE

Unlike prokaryotic cells, eukaryotic cells have several membrane-bound organelles. The mitochondria convert chemical energy from food into ATP, which is used to power all cell activities. The number of mitochondrion in a cell is determined by the cell's function. Muscle cells require a lot of energy, so they contain many mitochondria. The endoplasmic reticulum (ER) is a packaging and storage facility. Rough ER contains ribosomes and is responsible for protein synthesis. Smooth ER lacks ribosomes. It is responsible for the production and storage of lipids and steroids, as well as the storage of calcium ions. The Golgi body works with the ER to create complex molecules. In animal cells, the Golgi body also creates the lysosomes that break down food and cell waste.

Like animal cells, plant cells have mitochondria, rough and smooth ER, Golgi bodies, nuclei, and cell membranes. Unlike animal cells, plant cells do not have lysosomes. They also contain two unique organelles – cell walls and chloroplasts. The main function of a cell wall is structure and support. The primary job of chloroplasts is photosynthesis. These organelles contain chlorophyll, which traps solar energy. Plant cells also have a large central vacuole that stores water and helps the cell maintain its shape.
