They believe that Earth's water originated from extraterrestrial sources such as comets which brought water to the planet.
Hello friend!!
<span>Homeostasis is the process that helps control/maintain the body. The Circulatory System is one of the systems that is in the Homeostasis process. The Circulatory system is the system that is responsible for transporting blood throughout the body.
</span>
<span>The Circulatory System transports blood all over the body. The blood flows through the arteries. An artery is a small red tube that is connected to the heart and goes throughout the body. The Circulatory System is divided into 3 major parts the Heart, the Blood, and the Blood Vessels.
</span>
<span>The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.
</span>
<span>The organs in the digestive system need the circulatory system to continue to digest food.It needs the blood that the circulatory
distributes for it's nutrients,as well as to have the nutrients spread,so that the body functions evenly.
Hope It helps!!
All The Best!!</span>
Answer:
After being hunted almost to extinction, the humpback whale population has rebounded dramatically. Rapidly melting Antarctica ice poses a threat to coastal cities, but there is at least one species that is benefiting: Humpback whales are flourishing these days, due to an abundance of krill.
Pre-hunting population size may have been as many as 200,000-300,000 whales. They were estimated to number around 2,300 in 1998 and to be increasing between 2.4-8.4% per year. The IWC is undertaking an assessment of Antarctic blue whales at present.
Answer:
Decreases

Answer:
Mitochondria and chloroplast in Eukaryotic cells have their own DNA.
Explanation:
Researchers have found that mitochondria and chloroplasts in eukaryotic cells have their own DNA , they have their own DNA because Chloroplast and mitochondria are subcellular organelles that produces energy for the cells with their own genomes and genetic systems.
Therefore, when dna is replicated, it is transmitted to the daughter cells which produces cytoplasmic inheritance of traits and this is as a result of photosynthesis and respiration by the organelles Chloroplast and respiration.
