Your answer would be dendrites.

Dendrites look like branches coming off of the main body of the neuron. They receive electrical signals from axons, and then transmit them to the rest of the cell body.

Hope this helps!

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

Answer:

The smallest size tube that will hold the entire reaction is 0.5ml

Explanation:

25ul (DNA sample) + 25ul (enzyme) + 50ul (buffer) + 400ul (water) = 500ul total

since 1000ul=1ml, then 500ul = 0.5ml

Answer:

The device that mostlikely would not be used P20

Explanation:

P20 is a pipette used to measure and sample volumes of 20ul maximum.

Answer:

The reaction mix will have 400 units of the enzyme.

The working dilution will be 0.8 Units/ul.

Explanation:

The mix has 20ul of the enzyme which is 20Units/ul. Then we have 20ulx20Units/ul= 400 Units of enzyme in the mix.

Since the final volume is 500ul, the final concentration 400Units/500ul=0.8 Units/ul.
