Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity.
Answer:
Runners
Explanation:
stems are usually upright and prop up the plant to gather sunlight, however, some stems grow along the ground. These stems are called runners and the plant itself is called a stolon. Runners are involved in asexual reproduction of plants. They have nodes along them which can grow into another plant.
When food is digested, the food is broken down into Glucose, which can get into the bloodstream through the small intestines. It travels around the body in the bloods plasma and is then diffused into the body's cells through the capillaries. Once the Glucose is in the body cells, it can be used for respiration.
The breathing system is used in respiration because we need it to respire aerobically, so that our body gets all the vital oxygen it needs. When we breathe, oxygen is stored in the alveoli in the lungs. From there, it can be diffused into the bloodstream, to be used for respiration.
The products of aerobic respiration is Carbon Dioxide and Water. The Water leaves the body as sweat or waste such as urine. The Carbon Dioxide is carried through the blood to our lungs where we can breathe it out. Where as in anaerobic respiration, the product is Lactic Acid. This ends up being broken by oxygen after exercise (oxygen debt) and is also turned into Carbon Dioxide and Water.
Answer:
The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Explanation:
The genotype of F1 progeny is AaZz
The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"
Thus, total four allele pairs will be formed.
First allele pair would be - AZ
Second allele pair would be - Az
Third allele pair would be - aZ
Fourth allele pair would be - az
Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
