Answer:
Explanation:
Scenario 2: R is codominant with r.
Scenario 3: R and S are completely dominant to rand s, respectively; R and S are linked by 15 m.u. and do not interact with each other.
Scenario 4: Genes R and S perform the same function; R and S are completely dominant to r and s, respectively; and R and S are unlinked.
Scenario 5: R and S are completely dominant to r and s, respectively; R and S are linked by 10 m.u. and show dominant epistasis.
Answer:
Water vapor is a green house gas which absorbs the heat radiated from the earth's surface and keeps the earth warm. Clouds are formed by the condensation of water vapor in the atmosphere. They shield the earth from the sun by reflecting or scattering the solar energy and also trap the heat from the earth's surface. Thus both clouds and water vapor act like insulators from the sun and warms the planet.
Explanation:
When the earth’s surface get heated by the sunlight, some of the heat radiates back into the atmosphere and most of this heat is absorbed by gases in the atmosphere called green house gases. This process is called greenhouse effect, which keeps the earth warm. The green house gases mainly consists of carbon dioxide and water vapor.
Water vapor is formed through a process called evaporation. In this process, water from the ocean, rivers, and lakes evaporates to become water vapor using the energy from the sun. Water vapor also moves into the atmosphere by transpiration (plants) and sublimation (snow and ice).
The water vapor cools down and transforms into water droplets by a process called condensation, as it rises high in the atmosphere where the air is cooler. This water droplets that formed by condensation make up clouds. Low, thick cumulus clouds reflect majority of the solar energy straight back into space and thus cool the earth. High, thin cirrus clouds scatter the solar energy within the atmosphere and also trap the heat emitted by earth, thus warming the planet. Thus both clouds and water vapor act like insulators from the sun and warms the planet.
Chloroplasts, which capture sunlight and generate energy through the process of photosynthesis
Answer:
Duplication of Hox genes made increased morphological complexity possible.
Explanation:
- The hox gene cluster consists of a group of related genes that function to controls the basic body plan of an embryo and also define the head to the tail axis.
- These are mainly responsible for ensuring the correct position of al the structures in the body.
- Since the anterior-posterior axis all the vertebrates are established by these hox genes this points out to the fact that common information is needed amongst all he vertebrates to define the various morphological variations that occurred.
- The hox genes have shown duplication in the course of evolution and they have undergone a four-fold duplication which has led to the generation fo different structures in the various organism and is thus responsible for the increased morphological complexity.
