Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Equator area: closest to the sun and hot and humid due to the mass evaporation from the excess heat.
Mid equator/south pole: somewhat mild, colder, probably mid-humid, depending on which end of the midsection you're going for
South Pole: cold and dry. Cold because it's naturally far away from the sun (like the north pole) and dry because there isn't significant water evaporation here and any that may form crystallizes into snow and ice.
Answer:
Embryological evidence
Explanation:
Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.
There are two types of polymers which are natural and synthetic polymers. Natural polymers do not affect the environment but synthetic polymers do. This type of polymers are produced by humans. These release reactants which are considered hazardous to humans and the environment. Synthetic polymers include rubbers, plastics, and adhesives, and these are considered non-biodegradable and non environmental friendly. As these build up in the environment, in causes problems such as chemical poisoning to all the living things around it.
The answer is heterozygotes. Heterozygote offspring inherited different forms of a specific gene from individual parents. In a homozygous genotype, the offspring inherited same form of a specific gene from each parent.
