Answer:
Vascular Tissues
Explanation:
Angiosperms higher flowering plants it is most diverse group in a plant kingdom nearly 300,000 species of flowering plants are found under this kingdom.The angiosperms have specialised cells and tissues that carry out their metabolic functions and evolved vascular tissues (xylem and phloem) that translocate the water and nutrient to all parts of the plant. They are terrestrial, root system absorbs water and mineral from the soil. the shoot system supports and leaves involved in the process of photosynthesis
Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms
Q2) Condensation.
Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state
Q3)
Transpiration declines
Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.
Q4) the sun
sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.
Q5) Plants can’t use Nitrogen in the form of N2
N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.
Answer:
Skeletal muscles fibre are classified base on how the produce energy.
Explanation:
Skeletal muscles fibres consist of bundles of cells that form muscles which contain myobrills.
Skeletal muscles are classified based on how the produce energy;
Type 1 or slow pitch muscle fibres are more efficient and last for a long period of time. They are use for postural maintenance or endurance. It use aerobic respiration to produce energy or ATP.
Type 11 or fast twitch muscle fibres use anaerobic respiration and are for short speed and fatigue more easily than type 1.
Answer:
The above paragraphs describes that how salt- and fresh-water fish regulates their osmoregulation. Hence, the correct answer would be c. have adapted to deal with osmosis.
Osmosis is the process by which solvent's molecule move from region of low concentration (hypo-tonic) to the region of high concentration (hyper-tonic) through a semi-permeable membrane.
In sea-water fishes, the body fluids are hypo-tonic to the surrounding water and thus water is kept moving out of their gills. In order to prevent the excess water loss they need to drink water constantly and excrete concentrated urine.
In contrast, fresh-water fishes body fluids are hyper-tonic to surrounding water and hence, water keeps entering in their body through gills. So, in order to prevent excess dilution they absorb salt from surrounding with the help of gills and also their bodies reabsorb salt from urine.
