Answer: Lytic, because of the quick onset of symptoms after infection
Explanation: As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.
The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

Which of the following is an example of mechanical control of nonnative species? a. pesticides b. herbicides c. net barriers d. inspections please select the best answer from the choices provided a b c d
Answer:
The answer is c. net barriers.
Non-native species can do a great harm to native species or ecosystem and there are many ways to control them. Net barriers are mechanical control. Pesticides and herbicides are chemical control. There are also natural (biological control) control, such as diseases and pests, and environmental control, by altering the environment.

Don't forget to drink water!
why should we study soil what is the inportance of this unit
Answer: Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases. It is a very important aspect of the world. It can lead to many discoveries about the Earth.
Explanation: The soil is the foundation of basic ecosystem function.
Answer:
Soil is fundamental for a healthy food production. It provides essential nutrients, water, oxygen and support to the roots, all elements that favour the growth and development of plants for food production. Soil is the basis of food systems as well as the place where all plants for food production grow.

The biodiversity of cultivated crops is currently under threat from industrial
farming and climate change. The extinction of important crop plants
cause mass starvation. Which of the following is the best way for humans to could
use a seed bank to help prevent this problem?
• A. By
storing a great variety of seeds in case one variety goês
in the wild
extinct
• B. By storing a large number of seeds that can be eaten when famine
occurs
• C. By growing a large quantity of crops from seed and selling the
food they produce
• D. By growing a large quantity of
food they produce
crops from seed and storing the food they produced
The best way for humans to use a seed bank to help prevent the threat to biodiversity of cultivated crops is by storing a great variety of seeds in case one variety goes in the wild extinct.
What is biodiversity?
Biodiversity refers to the variety of life forms that exist on Earth, including the different species of plants, animals, fungi, and microorganisms, as well as the genetic diversity within each species, and the diversity of ecosystems and biomes. Biodiversity is important because it supports the basic ecological processes that sustain life on Earth, such as photosynthesis, nutrient cycling, and pollination. It also provides us with a wide range of ecosystem services, such as clean air and water, food, medicine, and cultural and recreational opportunities.
The best way for humans to use a seed bank to help prevent the threat to biodiversity of cultivated crops is option A, which involves storing a great variety of seeds in case one variety goes extinct in the wild. This approach is important because it helps to preserve the genetic diversity of crop plants, which is essential for breeding new varieties that can withstand changing climate conditions and resist diseases and pests. Storing seeds in a seed bank provides a backup in case a particular crop variety becomes extinct in the wild. It is a cost-effective way to protect the genetic diversity of crop plants and can serve as a long-term solution to the problem of food insecurity.
Option B, storing a large number of seeds that can be eaten when famine occurs, may provide short-term relief during a food crisis, but it does not address the root cause of the problem, which is the loss of biodiversity in cultivated crops. Option C, growing a large quantity of crops from seed and selling the food they produce, and option D, growing a large quantity of crops from seed and storing the food they produced, are both important for food production, but they do not directly address the problem of biodiversity loss in cultivated crops.
