<span>The epidermis is mainly a composition of cells called keratinocytes. Defensive cells are known as Langerhans cells and are one of the three types of specialized epidermal cells, The epidermis is bonded to the dermis. Hairs grow in the dermis and up to the epidermis. So, the dermis and the epidermis both have cells and hair. </span>
Answer:
C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.
Explanation:
When we look at the picture we can see that the line that goes from G to C, goes from a factory to the atmosphere. As we know factories release a great number of elements into the atmosphere being one of them, carbon dioxide. Therefore taking into consideration we can proceed to analyze the following statements.
A. Removing this step prevents photosynthesis in the next step: This is not true industry increases carbon dioxide in the atmosphere, even if they don't exist there is enough CO2 for plants to perform photosynthesis.
B.Removing this step increases the amount of carbon in the soil: This is not true as factories release carbon dioxide to the atmosphere, not the soil.
C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.
D. Removing this step increases carbon storage in plants: This is incorrect the carbon storage in plants is cording to their necessities independently of the abundance in CO2, in the atmosphere.
Answer:
The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.
Explanation:
The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.
Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.
Set up the equation.
Since gravity and liquid densities are fixed (for the most part), the height of the liquid is the largest variable in the equation. The equation reads as Pfluid = ρgh, where ρ is the density of the liquid, g is the acceleration of gravity, and h is the height of the liquid (or depth of the fluid)
<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>
Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.
<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
