It seems that you have missed the necessary options for this question, but anyway here is the answer. Glaucoma has been one of the leading causes of blindness and a common form has been linked to three genes and more that 20 genetic loci. So the statement that best describes glaucoma is that, <span>a polygenic trait that is influenced by the number of alleles present. Hope this answer helps.</span>
Chromatin is the lose form of genetic material & the "normal state" of DNA, RNA, and protein in the nucleus and in the cells.
Chromosomes are a condensed form of chromatin. Chromatin becomes chromosomes in the Prophase of Mitosis and Prophase 1 and Prophase 2 of Meiosis. It loosens again in the Telophase in Mitosis and Telophase 1 and Telophase 2 in Meiosis.
Sister Chromatids are made when chromosomes replicate during the cell cycle. The replication leads to the formation of the chromatids. The chromatids are joined by a single centromere. They separate during Anaphase 2 of meiosis.
I hope that this helps! Sorry if it doesn't I tried my best to explain!
Answer
The correct order to describe the carbon cycle would be;
• The carrot plant takes in carbon dioxide from the air during photosynthesis(3)
• The rabbit eats the carrot plant(2)
• The rabbit decomposes(1)
• The carbon compounds are returned to the soil (4)
Explanation
Carbon is captured in the food web through autotrophs (carrot plant) which undergo the process of photosynthesis. The captured carbon will utilized in making organic compounds (glucose). Heterotrophs (the rabbit) will feed on the carrot to allow the organic carbon to proceed into the food chain. Decomposers (acting on dead rabbit) release organic compounds and carbon iv oxide during breaking down of the decomposing matter. Biologically carbon is returned to the environment and soil after this stage.
Wave action carves away the coastline and Artificial structures stop the natural flow of sand along the coast are the causes of coastal erosion
Answer: Option B & D
<u>Explanation:</u>
Coastal erosion means the loss of the coastal land by removal of sediments. Coastal erosion mainly happens by the wave action which continuously hit the coast and remove the sediments. The materials taken by the waves should be replaced.
But man made constructions on the coastal area stands as a barrier. These constructions are not giving room for the sediments to get filled by the rivers draining into the Ocean.
the basic unit of structure and function of all organisms is cells
