External intercostal muscles between the ribs or of the sternum during inspiration.
<h3>what are the function of External intercostal muscles ?</h3>
Intercostal muscles are the group of muscles present between the ribs that create and move the chest wall.
The muscles have three layers such as external intercostal muscles, internal intercostal muscles, and the innermost intercostal muscles.
These muscles are supplied by intercostal nerves, intercostal veins, and intercostal arteries.
The external intercostal muscles are involved in forced and quiet inhalation.
They are involved in expansion of ribs and the chest cavity and originate from ribs.
The internal intercostal muscles are involved in forced exhalation but they depress the ribs and decrease space in the chest cavity.

I would say the last one. Yes, the coral reef in the south is being threaten but, it’s not the only one. Many other reefs are being threatened. Why? To find the problem to this reef you need to find the problems of other reefs and compare the data. Which ever the most problem cause you get rid of that first.
The slightest change in pH can destroy the substance or organism. The pH of a cell's interior helps regulate the cell's chemical reactions. For example, the pH of blood is 7.4, if blood falls to 6.8 or lower or 8.2 or higher, it results in death.

In <u>asexual </u>reproduction, genetically identical offspring are produced, while in <u>sexual </u>reproduction, offspring are genetically different from each other.
Sexual reproduction is a sort of reproduction that involves a complex existence cycle wherein a gamete (inclusive of a sperm or egg mobile) with an unmarried set of chromosomes (haploid) combines with another to provide a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid).
Sexual reproduction is the maximum common existence cycle in multicellular eukaryotes, which includes animals, fungi, and plants.
Asexual reproduction is a sort of reproduction that doesn't involve the fusion of gametes or change in the number of chromosomes. The offspring that get up by asexual reproduction from both unicellular and multicellular organisms inherit the whole set of genes in their single parent. Asexual reproduction is the number one shape of reproduction for single-celled organisms including archaea and bacteria.
