Distuseleimate source of2. Given reason for the following:(a) Mushroom is a sapo otroph(0 sun is theultimate souenergy for all living organish(c) The leaf of a plant dies out itare blocked.dies out if its stomanAV COLLEGE MANAGING COMMITTEE, New Delhi - 55​

Answer»

Answer:(a)-Mushrooms are fungi, and are usually placed in a Kingdom of their own apart from plants and ANIMALS. Mushrooms contain no chlorophyll and most are considered saprophytes. That is, they obtain their nutrition from metabolizing non living organic matter.

(B)-Sun is the ULTIMATE energy source for all living ORGANISMS." ✴This is because plants need sunlight to MAKE food through photosynthesis. This food is consumed by the animals and human-beings.

(C)-If they are blocked the leaf won't get any oxygen and will die of suffocation. The 'leaves of a plants dies' when 'stomata are blocked'. ... When the stomata of a leaf are blocked, the process of "photosynthesis" stops and so does the gaseous EXCHANGE and water vapour exchange

Is Darwin's theory of survival of the fittest working during Coronavirus pandemic? in 10 words​

Answer»

Answer:

Darwin theory is about struggle for survival and natural selection

Explanation:

Yes, the people who have better immune system are less affected by virus and THUS have more survival rate.

  • Charles Darwin advanced the idea of natural selection as a system FUNDAMENTAL the common determination that drives the development of life. Life forms with qualities more qualified to NATURE are chosen for endurance and pass them to the people to come.

  • Along these lines, when another contamination that the world has never observed ejects, the procedure of regular determination starts from the very beginning again.

  • With regards to the coronavirus pandemic, who is the "fittest"?

  • This is a difficult inquiry. Be that as it may, as immunology specialists at the University of South Carolina, we can say one thing is clear: With no compelling treatment choices, endurance against the coronavirus disease relies totally upon the patient's safe reaction.

  • We have been dealing with how the insusceptible reaction is a twofold EDGED blade – on one hand helping the host to battle contaminations, while then again causing noteworthy harm as immune system illnesses.

Mosquitoes leeches and Earthworm are Examples of ?​

Answer»

GAINESVILLE, Fla. – For the first time in more than 100 years, researchers have found that a species of mosquito feeds on the blood of earthworm and leeches, instead of frogs and toads like most other species. A study by University of Florida Institute of Food and Agricultural Sciences researchers demonstrates that mosquitoes take blood from a WIDER range of animals than previously understood, which may have implications for human health.

“Mosquitoes transmit disease-causing pathogens that affect humans and wildlife. Mosquitoes are the most dangerous animals to humans,” said Lawrence Reeves, a post-doctoral researcher at the UF/IFAS Florida MEDICAL Entomology Lab in Vero Beach, who LED the study. “Each mosquito species feeds on certain types of animals, but no mosquito species studied to date has been found to specialize on the blood of INVERTEBRATE animals—worms and leeches.”

According to Reeves, managing the impact of diseases transferred by mosquitoes is one of the greatest challenges facing researchers and doctors. “So, it is critical to understand which mosquitoes feed from which host animals because this determines how pathogens are likely to move through an ecosystem, and how humans may be impacted,” he said.

For the study, Reeves and his team collected blood-fed mosquitoes from multiple locations on the Florida Peninsula—from Columbia, Alachua, Indian River and Miami-Dade counties. Scientists used DNA, extracted from the mosquitoes’ blood meals, and a technique called DNA barcoding to determine what animals the mosquitoes were feeding on.

Researchers found that 100 percent of Uranotaenia sapphirina blood meals came from worms and leeches, Reeves said. Uranotaenia sapphirina is a common mosquito species throughout eastern NORTH America, where the host-use patterns of mosquitoes have been under extensive study since 1881, he said, when the link between mosquitoes and disease was recognized.

“The study demonstrates that the range of potential mosquito hosts is considerably broader than previously indicated,” Reeves said. “And, because previous research on mosquito-host interactions assumes that mosquitoes only feed on vertebrate animals, it is currently impossible to know how widespread invertebrate feeding is, or how this might impact the transmission of pathogens. This study really highlights that we still have much to learn about mosquitoes.”

For example, field-collected mosquitoes that feed exclusively on worms and leeches have tested positive for the Eastern equine encephalitis virus and the West Nile virus, Reeves said. “Our results suggest that Uranotaenia sapphirina is unlikely to become infected with these viruses by feeding from worms,” Reeves said. “It is possible that by feeding upon leeches, which themselves may feed on virus-infected animal hosts, this mosquito could come into contact with these viruses.”

Give reasons:1.Fresh milk is boiled before consumption while processed milk stored in packets can be consumedwithout boiling.2. Raw vegetables and fruits are kept in refrigerators while jams and pickles can be kept outside.3. Farmers prefer to grow pea and beans in nitrogen deficient soil.4. Mosquitoes can be controlled by preventing stagnation of water though they do not live in

Answer»

Answer:

Explanation:

1. Fresh milk is boiled before consumption to kill the microorganisms in it. But packed milk is pasteurised and does not contain any microorganisms. It can THUS be consumed without boiling.

2.Raw vegetables and fruits are kept in refrigerators whereas pickles and jams are kept outside. It is because pickles and jams contains some preservatives such as sugar, salt and other ingredients in them. Though, pickles and jams do not easily get spoil by bacteria, air or other factors when you are kept them outside.

3.BEAN and Peas are leguminous plants. They fix nitrogen in the soil with the help of Rhizobium bacteria PRESENT in the root nodules of the plants. Thus, they fix nitrogen and replenish the deficiency of nitrogen in the soil. Therefore, farmers prefer to grow bean and peas in nitrogen deficient soil.

4. Mosquitos can be controlled by preventing stagnation of water though they don't LIVE in water because mosquitos lay their eggs in stagnated water, they get most nutrients after hatching from water and then they spread diseases like dengue , MALARIA , chikungunya etc.
