DNA is copied during cell division
Answer:
Solar Radiation
Explanation:
Increased carbon dioxide in the atmosphere leads to increased absorption of Solar Radiation.
Answer:
water molecules undergo the 'tug of war' via the cohesion-adhesion theory
Explanation:
In plants specifically, a transpiration stream is formed via osmosis from roots into xylem and travels by the apoplast pathway to the leaves, where the water then evaporates from stomata into the surrounding air along the diffusion gradient. the water loss from the mesophyll cells lowers their water potential therefore water moves in via osmosis by both apoplast and symplast pathway from adjacent cells. water bonded to water= cohesion, water bonded to carbohydrates of xylem walls= adhesion. water is drawn up in tug of war-esc fashion against gravity to replace water evaporated, resulting in cohesion-adhesion theory.
Answer:
<em> The carrying capacity is determined only by the density-dependent factors.</em>
Explanation:
The maximum number of organisms of a particular species that an environment can hold is known as the carrying capacity of that environment. The carrying capacity depends on density-dependent factors as well as density- independent factors like weather, sunlight etc.
Beyond the carrying capacity, the organisms will begin to fight with each other for limited resources. The environment will become unstable as the resources will be scarce and individuals will be more.
Explanation:
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
The main causes of climate change are: Humanity's increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry. Deforestation
Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
