Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
Answer:
capillary, arteries, veins
Explanation:
capillary are tiny blood vessels connecting arteries to veins
Answer:
Thylakoids, stroma
Explanation:
The interconnected flattened sacs within the inner membrane of the chloroplast are called thylakoid. Many thylakoids are come together and get arranges in a stack called a granum.
Thylakoid contains chlorophyll pigment and is responsible for absorbing the sunlight and conducting light reaction. These thylakoids or grana are suspended in a liquid called the stroma.
The stroma contains the enzymes which are required in the light-dependent reaction. It contains DNA, ribosome, starch. The synthesis of organic molecules occurs in the stroma.
