Answer:
Through natural selection, organisms carrying better traits to survive in an ecosystem are able to survive and pass on their characteristics to their offspring. Through evolution, the allelic frequency of the population changes in abundance of the traits which are favoured by natural selection. As the male pom-pom monkeys carrying long bright puffs of turquoise fur all around his neck had a better adaptation to survive on the island hence, they were favoured by natural selection and through evolution all long bright puffs of turquoise fur all around his neck evolved.
The answer are Dyspnea and wheezing. It is lungs air sacks
become inflamed, a common lung infection called pneumonia. The causes of this pneumonia
is viruses, fungi or bacteria. The air sacs is also filled with fluid, pus and
cellular debris. There are many ways why a child or a person catches bacterial
pneumonia, one of those is the spread via air-borne droplets from a cough or
sneeze.
The difference is 1) sugars dissolve in water lipids don't. 2) sugars are made-up of subunits that form large polymers and lipids are not and don't form polymers. 3)Lipids store more energy than sugars hoped i helped
Answer:
In bryophytes, the sporophyte is minute and dependent on the relatively prominent and nutritionally independent gametophyte for resources. The moss gametophyte looks like a miniature herb, with tiny leaf-like photosynthetic organs. The gametophyte generation begins as a dormant spore, which germinates under appropriate conditions to produce filamentous and branching protonemal tissues. These form multicellular bud-like structures, each of which develops into a leafy shoot. The mature gametophytes produce male and female sexual organs, the antheridia and archegonia, respectively. The gametophyte is often sexually distinct, and plants are either male or female.
Each antheridium has an outer layer that encloses and protects thousands of motile sperm, which swim through available external water layer to the egg. Fertilization at the base of the cylindrical archegonium produces a diploid zygote which develops into an unbranched sporophyte. The sporophyte consists of a thin stalk attached to the gametophyte, and a capsule that encloses the sporophytic meiotic cells.
In recent years, the mosses Physcomitrella patens and Funaria hygrometrica have emerged as attractive model systems for studying gene function in non-vascular plants because of the relative ease of molecular manipulation by homologous recombination. Mutants affecting gametophyte development have been isolated and their analysis should provide insights into the molecular basis of gametophyte development in mosses.

Answer:
A pump in the hemodialysis machine slowly draws out your blood, then sends it through another machine called a dialyzer. This works like a kidney and filters out extra salt, waste, and fluid. Your cleaned blood is sent back into your body through the second needle in your arm
