Answer:
Choose the correct label for each part of the experiment.
The plants that are under a UV light for eight hours
A. Experimental group
The amount of water that is given to all of the plants
D. controlled Variable
The plants that are under the light for six hours
B. Control Group
Explanation:
Compounds microscope is an optical instrument for forming magnifying images of small objects having an objective Len with a very short focal length. While electron microscope is a high power of microscope uses beam of electron focused by magnetic lenses instead of rays of light.
Answer:
The correct hypothesis would be - C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Explanation:
Burmese pythons are the invasive species in this new region as they originally found in South Africa, and also one of the largest snakes so they lack natural predators in this new setting or region.
These snakes depend on both types of food which means they are omnivorous and eat both herbivore and carnivores prey.
Thus, the correct answer is - Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Answer:
Adaptations to a common environment and examples of convergent evolution
Explanation:
Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
Answer:
They'll form a mesh that plugs what ever injury. The platelets can change its round shape to a spiny shape and will release substances that entrap more platelets. Proteins will enlargen and become a Blood Clot.
