Answer:
Monocots have only one seed leaf inside the seed coat. Dicots have two seed leaves inside the seed coat.
Explanation:
Monocots: Often only a thin lead, because the endosperm to feed the new plant is not inside the seed leaf.
Dicots: Usually rounded and fat, because they contain the endosperm to feed the embryo plant.
Answer:
Pollution.
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
Explanation:
Lentic environment is a stationary or still water, i.e water that doesn't flow but it is stationary at one place. Examples are ponds, ditches, reservoirs, lakes , pool, seep.
The major challenges of lentic environment are;
It become reservoir for waste deposition.
Habitat of bacteria growth.
Organisms in them die due to lack of food resources.
It's lead to algal bloom.
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
Answer:
Please look at the explanation section
Explanation:
In the oxidative phase of the pentose phosphate pathway, NADPH molecules and ribose-5-phosphate molecules are created. The function of NADPH molecules is to build other types of molecules. For example, RSP sugar is used for the production of DNA and RNA creating S-phospho-D-ribose alpha-1 pyrophosphate, and, if there is an excess of ribose-S-phosphate, said excess may not be used to biosynthesis and therefore it is transformed into other sugars that can be used by the cell for metabolism.
Answer;
-Tropical rainforest; tropical seasonal forest
In contrast with the tropical rainforest, the soil of the tropical seasonal forest is more nutrient-rich and this type of biome has fewer insects, parasites, and fungal diseases. therefore, in many places, these areas are highly endangered.
Explanation;
The tropical rainforest is one of the world's most threatened biomes, despite being home to some of the most diverse and unique species on the planet. The tropical rainforest is a biome with a constant temperature and a high rainfall. The level of humidity and density of the vegetation give the ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by human expansion.
The tropical seasonal forest has more or less densely growing trees which lose their leaves during the dry season. It typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season.
