List the sequence of events that occur as the avocado seed germinates.

Answers

Answer: The sequence of events of avocado seed germination includes:

Water absorption --> enzyme activation --> radicle emerges --> lengthening of the hypocotyl --> growth of epicotyl and plumule development --> shrinking of the cotyledons.

Explanation:

Germination is defined as all the changes that occurs when a seed embryo resumes it's growth and development to become an independent seedling. Seeds usually germinate in two ways:

--> EPIGEAL germination: in this type of germination, the hypocotyl grows rapidly and elongates, carrying the cotyledon above the soil.The AVOCADO seed is a typical example of a dicotyledonous plant.

The sequence of events of avocado seed germination starts by imbibition which is the rapid in take or absorption of water by the seed through osmosis. Hydration of the embryo activates the enzymes in it which converts insoluble stored food materials into soluble forms. The testa splits and the radicle emerges first. It grows downwards as the primary root from which root hairs and branch roots arise( to form a tap root system). Next, the hypocotyl lengthens, pushes its way up through the soil carrying with it the cotyledons and the plumule. The cotyledons turn green on exposure to sunlight and start to photosynthesize. The epicotyl then grows and the plumule develops into a green shoot. By the time the first foliage leaves grow and begin to photosynthesize, the cotyledons shrink and drop off.

Answers

      

Zoonotic diseases are animal diseases that can be transmitted to humans. Transmission can be by ingestion, inhalation, bites, scratches, contact with contaminated products, and vector-borne. There are over 200 zoonotic diseases that can possibly threaten your health and involve several different causative agents, such as bacteria, parasites, viruses, and others. I am only going to inform you of just a hand full that is caused by bacteria and contaminates cattle. Once the cattle on large commercial farms become infected it can be a challenge to get rid of and contain.

Wash hands before and after animal handling.

1. Do not eat or drink in the animal housing areas. 

2. Wear coveralls, farm specific clothing or laboratory coats when handling animals.

3. Avoid handling sick animals or animals with lesions unless gloved.

4. Wear a mask if you are allergic to animal hair or dander or if feed or bedding dust is present.

5. If you are sick, DO NOT enter the agricultural animal facilities.  You are more susceptible to other infective agents and you may transfer pathogens to the animals!

6. Routinely wear gloves when cleaning animal area.

7. Note progression of any illness.  Report illnesses to your supervisor. 

8. Inform physician of your animal related activities.

Which approach would be least helpful in determining genetic differences between species?

Answers

Answer:

the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff

Explanation:

Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.

What is an example of this ?

For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.

In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.

This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.

Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.
