A human cell is shown in the diagram.
Which part of the cell determines if the human is a male or female?
A Organelle 1
B Organelle 2
C Organelle 3
D Organelle 4
Answer:
Organelle 1
Explanation:
Organelle 1 is the nucleus which stores genetic material such as the xx or xy chromosomes which contain the information for what gender a person is.
In the cell, the organelle 1 or nucleus determines if the human is a male or a female because it contains the chromosome which determines gender of a person. Thus, the correct option is A.
What is Nucleus?Nucleus is the organelle of the cell which is also known as the brain of cell. It is because this organelle contains all the information of the cell such as genetic information which determines the proteins which are translated in the cell.
Nucleus contains the genetic information in the form of chromosomes which carry genes. There are 23 pairs of chromosomes in a nucleus which is composed of 22 pairs of autosomes and 1 pair i.e., the 23rd pair of chromosome is the sex chromosome which can be XX or XY. This 23rd pair of chromosome determines the gender of a person. XX develops into female while XY develops into male.
Therefore, the correct option is A.

Reproduction processes can produce offspring similar to and different from the parent
organisms. Which of the following would produce the most similar offspring?
F cutting a portion of a potato that contains an eye or bud and planting it in a
vegetable garden
G butterflies bringing pollen from one wildflower plant to another plant as they gather
nectar
H a scientist that cross-pollinates bean plants by transfer pollen from one flower to
another
J a bee collecting pollen from one flower to delivering it to other flowers within a
field.
Cutting a portion of a potato that contains an eye or bud and planting it in a vegetable garden would produce the most similar offspring due to vegetative propagation.
What is vegetative propagation?Potatoes are almost exclusively cultivated using vegetative means (cloning). Potato tubers each contain their own nodes or eyes, which are the origins of new growth. The new stalks that emerge from each eye are referred to as sprouts, and these are what give the young plant its start.
The offspring of plants that reproduce vegetatively are new plants that are genetically identical to their parents because they form from the vegetative components of their parents' plants. The progeny that are produced through vegetative reproduction are referred to as clones because of this.
Therefore, Cutting a portion of a potato that contains an eye or bud and planting it in a vegetable garden would produce the most similar offspring due to vegetative propagation.
