Answer:
1. Bryofita
2. vascular plants
3. Seed vascular plants (gymnosperms)
4. Angiosperms
Explanation:
1. Bryofita
Around 475 million years ago, the origin of plants was thought to originate from aquatic ancestors (green algae). Adaptation to terrestrial life is proven by the presence of sporopolenin and layered gametangia that protect gametes and embryos. This adaptation occurs in bryophytes which are the first terrestrial plants. Bryofita or mosses develop into various vanations in their group. Most briolites do not have vascular tissue (water from the environment is diluted and absorbed by the SD, but some briophytes have water-carrying vessels.
2. Vascular plants
Around 400 million years ago, the evolution of plants was marked by the diversification of vascular plants (vascular plants). These early vascular plants are seedless plants, for example in the types of ferns seria into other groups of seedless plants.
3. Seed vascular plants (gymnosperms)
Plant evolution begins with the appearance of seeds, which are structures that protect the embryo from drought and the threat of environmental change. The emergence of these seed plants accelerated the expansion of plant colonization on land. Plant seeds consist of embryos and food reserves that are protected by a cover. Seed vascular plants appeared about 360 million years ago with the appearance of Gymnosperms. Gymnosperms consist of conifers with a variety of types. Conifers and ferns dominate life in the months between more than 200 million years.
4. Angiosperms
About 130 million years ago marked the emergence of flowering plants that have a somewhat reproductive structure
complicated where the seeds are protected by a room called the ovary.Because the seeds are protected in such a way that this group discusses closed seed plants or Angiosperms

It can be a heat insulator, which means it can trap heat in and reduce heat loss to keep us warm.
it can also protect organs, it can act as a shock absorber
Attribution theory refers to how the social perceiver uses information in trying to explain casual events in everyday life. This primarily discusses as to how the information gathered are combined with in order to create a casual judgment. According to Heide (1958), people are like naive psychologists who are trying to figure out how and why things happen. For example, if someone with a bad family background succeeds, people will say that he used his struggle as a motivation and if he fails people will say that he succumb to the challenges.
Answer:
<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.
<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.
<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.
Explanation:
All of these sugars are polysaccaride sugars containing large number of glucose subunits.
Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.
Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.
Cellulose is the storage form of glucose in plants and leaves.
Answer:
The United Kingdom.
Explanation:
A republic can be defined as a form of government that is typically being ruled by the people.
In a republic, the citizens of the country have the supreme power and as such they are saddled with the responsibility of voting to elect representatives who make laws, decisions and govern the country.
All of the following countries are a republic;
I. Egypt (Arab Republic of Egypt).
II. United States of America.
II. Russia (Russia Federation).
<em>However, the United Kingdom is a unitary nation that practice both parliamentary democracy and constitutional monarchy. The parliament of the United Kingdom comprises of two chambers and these are the House of Commons (lower chamber) and the House of Lords (upper chamber). </em>
