Answer:
False.
Explanation:
All of the things found in the Earth system can be categorized into four (4) main categories and these includes;
I. Land: this subsystem forms a sphere which is generally referred to as litosphere.
II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.
III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.
IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.
If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.
Answer:
Asexual reproduction is a type of reproduction that doesn’t involve gametes fusing or the change in the number of chromosomes. A spider plant is the perfect example of asexual reproduction, but when it comes to plants like that, it’s referred to a type of asexual reproduction called vegetative propagation.
Answer:
The best answer to the question: The preferential use of phosphatidylinositol and phosphatidylethanolamine in the cytoplasmic leaflet of membranes leads to increased:___ would be, D: All of the answers are correct.
Explanation:
There is still a lot of debate among scientists as to the exact way in which phospholipids are distributed between the two leaflets of a cell´s plasma membrane, but what they do know is that there are four kinds, and that phosphatidylinositol (a sterol) and phosphatidylethanolamine appear most commonly on the cytosolic, or cytoplasmic side of the membrane. They also believe that it is this particular arrangement which allows the cytoplasmic side of the membrane to be slightly negatively charged and this role will play a major part in a membrane´s ability to generate an action potential. Also, it is known that these negatively charged ends of the bilayer will allow certain proteins, positively charged ones, to be inserted, and connected to it, to become transporters, or mediators in action potentials and normal activities of cells. Finally, since fatty acids and cholesterol are associated with phospholipids, but have a tendency to be attracted to these particular two types, they tend to give the overall structure fluidity, but also permit the inner leaflet to assume its particular circular shape around the cytoplasm. This is why the answer is D.
Answer:
A.Radiation is the answer
Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.
According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.
Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
