After pollination and fertilization following changes occur in a flower: The petals, stamens, style and stigma of the flower fall off. Sepals dry up and hold the ovary. The ovules confined in the ovary develop into seed
Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
<h2>Answer is option "C"</h2>
Explanation:
- All in all, this procedure includes a "parent" cell parting into at least two "little girl" cells. Right now, parent cell can give its hereditary material from age to age.
- Meiosis, then again, is a particular type of cell division that happens in living beings that imitate explicitly. As referenced above, it produces regenerative cells, for example, sperm cells, egg cells, and spores in plants and parasites.
- In people, extraordinary cells called germ cells experience meiosis and at last offer ascent to sperm or eggs. Germ cells contain a total arrangement of 46 chromosomes (23 maternal chromosomes and 23 fatherly chromosomes). Before the finish of meiosis, the subsequent regenerative cells, or gametes, each have 23 hereditarily one of a kind chromosomes.
- Hence, the right answer is option C "four strings, each a combination of different colors"
Greenhouse gas emissions will continue to increase in the short term, but as new technologies are discovered and implemented by governments and industries, this may eventually reverse. Global climate may continue to warm, but once greenhouse gas emissions are lowered, this may slowly reverse. Current solutions are not yet enough to stop the increase in temperature, but some technologies on the horizon are promising, such as carbon capture and storage, solar energy, and aquaculture of biofuels. One immediate way to reduce greenhouse gas emissions is a change in lifestyle, for example, using less fuel-intensive transportation options and saving electricity.
Answer:
A genetic disorder that is inherited as a recessive trait is sickle cell anemia.
Explanation:
Sickle cell anemia can be described as a disorder which is caused by a mutation in the hemoglobin beta gene which is found on chromosome number 11. The pattern of inheritance of sickle cell anemia is autosomal recessive which means that both the alleles of the gene shall be recessive for the trait to occur. A person with one recessive allele for the trait will not carry the disease but will be a carrier for the disease.
