Which list represents the proposed sequence in plant evolution?​
Phoenix [80]

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

lapo4ka [179]

Answer:

Yes, I think this scheme can work. The chippings will provide enough ethanol to power the mower. The mover requires up to 15% ethanol. As he is distilling it to 95% ethanol, it would be more than enough for the mower to work. And also he can use the remaining ethanol for other purposes like powering Joe’s car or to create alcoholic beverages to drink when Joe’s friends come over to watch UCLA football games on Saturday afternoons.

BabaBlast [244]

Answer:

50

Explanation:

A punnet square can be described as a diagram which illustrates all the possible outcomes of a cross. It is used to tell about the percentage chances for the kinds of genes being transferred to offsprings.

In order to check the percentage of red flowers we can draw a punnet square. As red flower is a recessive trait and pink flower a heterozygous trait,the punnet square shows that a cross between them will give 50 percent red flowers and 50 percent pink flowers.
