Answer:
1. reducing soil erosion,
2.Controlling runoff water
Explanation:
Contour farming mitigates the impacts of floods, storms and landslides on the crops by reducing soil erosion up to 50 percent, controlling runoff water, increasing moisture infiltration and retention and thus enhancing soil quality and composition
The smoke from prescribed burn and managed wildfires is an extremely toxic air pollutant that is very dangerous to<span> unborn fetuses, infant children and elderly people</span>. It also affects normal healthy people without warning. Wood smoke pollution is 12 times more carcinogenic than cigarette smoke, attacks the body cells up to 40 times longer, and kills at least 40,000 adults and children every year. It contains a toxic soup of more than 4,000 chemical compounds of harmful gases and particle matter that go deep in the lungs and kill people, 69 of which are known human carcinogens, including arsenic, particulate matter, ozone, sulfur dioxide, carbon monoxide, hydrocarbons, dioxin, nitrogen oxides, and radioactive material. Warnings to stay inside on high pollution days are misleading and false. The tiny particles and gases seep inside of homes reaching up to 70 percent of the outside pollution level. No one is safe inside or outside of their homes.
Cladogram is a diagram that tells the relationships between different groups of taxa called “clades”. Cladogram gives phylogeny (evolutionary history) of the taxa. The organisms which share derived characteristics are grouped together while constructing a cladogram. Jelly fish is a cnidarian share common characteristics such as radial symmetry, simple tissues and no body organs with other members like corals and sea anemones.
Answer:
F-actin is a double helical filament as opposed to G-actin,which is a globular protein .Each actin filament has two ends,called the plus and
the minus ends, which makes it recognizable from each other.This gives the structure a distinct polarity.
Explanation:
Actin is the most abundant protein that is found in almost all eukaryotic cells.Its a most important part cytoskeleton as its a monomeric subunits(size 42kDa) of two types of filaments i.e. microfilaments and thin filaments in cells. Actin is essentially required to maintain stability and morphogenesis of cell.It is involved in numerous significant processes such as endocytosis,cell division and migration.Actin is present in two forms:
•G-actin
•F-actin
The two forms of actin are different structurally.
G- actin is a globular shaped protein,usually present in free form(a monomer),having a tight binding site for another actin monomer.Each monomer has ATP. Upon polymerization of G-actin monomers, a polymer called F-actin filaments is form. This process is driven by hydrolysis of ATP.
The answer is C. Hope i could help
