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

Answer:
B- Most of the glucose 6-phosphate enters the pentose phosphate pathway.
Explanation:
Since the cell requires much more ribose 5- phosphate than NADPH, then it would lead the glucose 6-phosphate down the oxidative phosphate pathway to create ribulose 5-phosphate, which can be isomerized to ribose 5-phosphate depending on the cell state.
Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.
Biogeography deals with the distribution of species across the mother earth.
Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.
Anatomy deals with the study of the similarities and difference that exists among different species or organisms.
<u>Explanation: </u>
As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.
Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.
Answer : Yellow
Explanation : Because purebred plants have lighter colored dominence .
Answer:
7.5cm
Explanation:
Velocity vs Time Graph:
When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.
Velocity vs time graph:
Is shown in the attached image
A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.
Height of the triangle is the velocity (v) = 0.75m/s
The base of the triangle is the time interval (t) = 0.2sec
Distance travelled = Area of triangle
Distance travelled
= 1/2(V) * t
= 1/2(0.75m/s) * 0.2s
= 0.0075m
=7.5cm
Thus, during one beat blood flows 7.5 cm
