Give two similarities and two differences between gymnosperms and angiosperms.
kakasveta [241]

<span>Similarities</span> between Gymnospermes and Angiospermes:


<span>·         </span>Having seed-Gymnospermes and Angiospermes are types of plants bear seeds. They belong to a single class known as Spermatophyta. Spermatophyta or seed plants are those <span>plants that produce seeds.</span>

<span>·         </span>Diferentiation- The sporophyte (diploid multicellular stage in the life cycle of a plant) of both,<span> Gymnospermes and Angiospermes,</span> is differentiated into root, stem, and leaves.


Differences between Gymnospermes and Angiospermes:

 

<span>·         </span>Seed-Although both have seeds, differences between them are huge. Gymnospermes have bare, non-encased seeds. The term "gymnosperm"  in Greek means "naked seeds". On the other hand, seeds of Angiospermes are enclosed within an ovary, usually in a fruit.

<span>·         </span>Pollination- In Gymnospermes, the pollination is by wind, unlike most Angiosperms, who use insects, mammals or birds.  Gymnosperm flowers are often difficult to spot because they are not out to attract flying pollinators.

In 1848, Phineas Gage, a railroad construction foreman, survived when an explosion drove an iron rod through his head damaging t
Romashka-Z-Leto [24]

Answer:

Case study

Explanation:

Phineas Gage: a case study.

An error in the procedure caused that, when this worker tried to compact the powder placed in the cavity using a metal bar, a spark would jump. The explosion of the mixture occurred a few centimeters from the face of the young man and, as a result, the metal bar one meter long and about three centimeters in diameter pierced his skull before landing more than twenty meters from where he presumably.

When Gage returned to work in the work, the measured and cordial worker that everyone knew had disappeared to give way to a person with bad temper, easy to irritate, given to insults, prone to waste and with a very short-term vision of the lifetime. He was, in general, an impatient and irreverent person, who let himself be carried away by desires, fruit of a whim, and who thought little of others.

This little historical episode is a mandatory stop in many university careers related to neuroscience and behavior because, in fact, it was one of the first well-documented examples in which it was seen how material changes in the brain modified not only cognitive abilities, but aspects of psychology that have traditionally been associated with the "soul", that is, the way of being and the essence of human beings.

Somehow, the accident of the metal bar served to indicate the biological bases on which rather abstract psychological processes are sustained, such as the management of emotions and decision-making. In addition, the case of Phineas Gage also served to reinforce the hypothesis that different areas of the brain deal with different aspects of behavior.

Biological transmission differs from mechanical transmission in that biological transmission involves reproduction of a pathogen
Taya2010 [7]

Biological transmission involves reproduction of pathogens in an arthropod vector prior to transmission. In terms of epidemiology, we can term a vector as an organism that is from infected to the uninfected. An infected organism which develops biological vector passes it to its host. For example a mosquito.

 A mosquito being a mechanical vector carries an infected organism to its host either through the legs or through the other body parts
