Answer: Yes, the zoonotic is the infectious diseases that can be contracted by the people who handle birds.

Explanation:

Zoonotic is the infectious diseases that can be transmitted through birds. Highly infected birds are infectious to the other organism as, it is transmitted from one person to another.The zoonotic infection are caused by the viruses, fungi and bacteria.

Example of zoonotic disease are:

Animal flu and bird flue
Anthrax
Cat scratch fever

What is the name of the system that transports products of photosynthesis?

julsineya [31]

Plants have two systems for the transportation of substances - using two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant.

Plants maintain higher levels of phytochrome at their growing tips where phytochrome plays important roles in growth responses t

Naddika [18.5K]

Explanation:

Phytochrome is a protein with kinase activity present in plant organisms, whose function is to act as a photoreceptor mainly of red light (600-700nm) and distant red light (700-800nm), thanks to its chromophore. The phytochrome depending on the type of light detected can trigger different responses in the plant, such as flowering, germination, growth as an escape response to the shadow -development of epicotyls at night and cotyledons during the day-, regulation of expression of metabolic activity during day and night (circadian rhythms).

Phytochromes were discovered in the fifties as part of an investigation on the effect of light on the germination of lettuce seeds. It was observed that the seeds that germinated in the dark did not reach 20%; On the contrary, the germination percentage was maximum when the seeds were irradiated with a pulse of red light (R). It was also found that subsequent irradiation with a pulse of distant red light (RL) nullified the inducing effect of red light, preventing germination.

Alternating irradiation with light R and RL (R, R + RL, R + RL + R, R + RL + R + RL, etc.) showed that the last color applied determined the germination of the seeds and that the light red was the stimulating factor of the process and, its inhibitor, the distant red light.

In search of an explanation of such phenomena, the existence of a pigment was proposed, which they called phytochrome, which absorbed the red light. The phytochrome in question, after absorbing red light, became a way capable of absorbing distant red radiation; form that turned to its initial condition after performing said absorption. The hypothesis found experimental support in the early sixties with the purification, from extracts of cereal seedlings, of a protein endowed with the predicted characteristics. Phytochromes are soluble proteins found in the seeds, leaves, stems, roots and other organs of the plant.

Biochemically, phytochrome is a protein with a Bilin chromophore.

A geochronological scale measured in Millions of Years Ago or M Y A. Mesozoic era: Triassic period, 250 to 201 MYA, first dinosa

motikmotik

Answer:

D. The first flowering plants were introduced toward the end of the Mesozoic era.

Explanation:

Following the Paleozoic Era, the Mesozoic Era or Age of Conifers began approximately 250 million years ago. This major geological era brought about the ancestors of many of the plant and animal groups still in existence today.

The Mesozoic era is marked by 3 divisions:

the Triassic Period,
the Jurassic Period,
and the Cretaceous Period.

Animals and plants slowly recovered after the mass extinction in the Permian-Triassic extinction that led to the eradication of most aquatic marine species. They evolved to exploit varying niches in their environment, leading to a boom in terrestrial animals. Over time the planet's increasingly warm climate, abundant in atmospheric oxygen and carbon dioxide, contributed to the growth of diverse megaflora, that rapidly dominated the planet's terrestrial biosphere.

By the end of the Mesozoic Era, in the Cretaceous period, flowering plants (angiosperms) largely replaced the dominant seed ferns of the Triassic, and the conifers, cycads and gymnosperms of the Jurassic.

Varied dispersal mechanisms in angiosperms co-evolved with the evolution of certain types of fauna. Plants used animal life, including herbivorous reptiles and early mammal-like species to disperse large seeds.
