Answer:
The process of Mitosis ensures that each new cell receives the proper of chromosomes
The correct answer for the given question above would be option B. Thale cress <span>is a plant that is genetically engineered with genes that break down toxic materials, so this would be a transgenic type of organism. By definition, transgenic organisms undergone genetic engineering wherein genes of a particular specie is modified or transplanted into another. Hope this helps.</span>
The answer for this question is "founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results" so it is letter A
A species that is habitat specialist and lives at the highest elevation.
Explanation:
An ecosystem consist of plants, animals as well as micro-organisms but due to climate change the plants as well as animals are in danger . The case that has been provided in the question where due to climate change the temperature rises as a result the species living at the highest elevation are in problem .
Due to rise in temperature the snow is melting and the sea water level is rising. The animals and plants adapt themselves according to the climate where they are residing but suddenly if climatic change take place they will be unable to survive.
The animals which are mostly affected due to climatic change are snow leopard, polar bear, giant panda.
<em>Water has unique chemical characteristics in all three states—solid, liquid, and gas—thanks to the ability of its molecules to hydrogen bond with one another. Since living things, from human beings to bacteria, have a high water content, understanding the unique chemical features of water in its three states is key to biology.
</em>
<em>In liquid water, hydrogen bonds are constantly being formed and broken as the water molecules slide past each other. The breaking of these bonds is caused by the energy of motion (kinetic energy) of the water molecules due to the heat contained in the system.
</em>
<em>When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.
</em>
<em>On the other hand, when the temperature drops and water freezes, water molecules form a crystal structure maintained by hydrogen bonding (as there is too little heat energy left to break the hydrogen bonds). This structure makes ice less dense than liquid water.</em>
