Interesting facts about bacteria and viruses 1st two answer gets the Brainliest. :)
Answer:
Explanation:
Bacteria are very tiny organisms that are present everywhere. Bacteria are single celled microorganisms . Their cell structure is unique and they don't have nucleus .
Interesting facts about bacteria :
There are around 40 million bacteria in a gram of soil .Bacteria can survive in even very harsh conditions like deep areas of earth crust and in radioactive waste.Some bacteria have chemicals that can generate light . This process is called bio-luminescence.Many bacteria are present in human body.Bacteria also help the environment by treating sewage .Viruses are very small particles that can infect animals and plants . Viruses are made up of genetic materials like DNA and are protected by a coating of protein.
Interesting facts about viruses :
Viruses are not classified in any of the five kingdoms of living organisms.Most of the viruses are so small that they cannot be seen even with an optical microscope.The first human virus discovered was yellow fever virus in 1901. A virus that contains RNA instead of DNA is sometime called a retrovirus.The word virus comes from Latin word " virulentus " meaning " poisonous " .Hybrid tall pea plants were let to self pollinates and produces 1064 seeds. How many of them do you expect to be pure tall?
a. 354
b. 266
c. 532
d. 798
Answer:
c 532 pure tall I think it right or wrong
All of the offspring will be tall, we would expect that all 1064 seeds produced would be pure tall. This means that the answer is c. 532, since 1064/2 = 532.
What is hybridization?Hybridization is the process of breeding two individuals of different varieties, strains, or species to produce offspring with traits from both parents. This can occur naturally, through the cross-pollination of flowers or the natural mating of animals, or it can be artificially induced by humans through techniques such as selective breeding or genetic engineering.
Hybridization is often used in agriculture and horticulture to produce crops or ornamental plants with desirable traits from different varieties or species. For example, hybrid corn was developed by crossing different varieties of corn to produce plants with improved yields, disease resistance, and other beneficial traits. In animal breeding, hybridization is used to produce animals with specific characteristics, such as hybrid dogs that have traits from different purebred parent breeds.
Hybridization can also occur in nature when two different species come into contact and are able to breed. This can lead to the creation of hybrid species, which are offspring that have characteristics of both parent species. Hybridization can sometimes lead to the creation of new and unique species, but it can also cause problems, such as the introduction of invasive species or the erosion of genetic diversity.

What is the main difference between food chains and food webs? (1 point)
o Food chains focus on energy transfers, but food webs do not.
o Food webs do not show connections between animals like food chains.
o Food chains focus on the internal energy cycles of animals, unlike food webs.
O Food webs are more complex than simple food chains
Answer:
The answer is D: Food webs are more complex than simple food chains.
Explanation:
A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.
Hope this helps!! ;)

#7 A cuckoo bird lays its eggs in a warbler bird's nest. Once hatched, the cuckoo chicks displace the warbler chicks, tricking the parent warbler into caring for them over their own young. What type of ecological interaction does the cuckoo have with the warbler?
a. Commensalism
b. Competition
c. Mutualism
d. Parasitism
Answer:
Parasitism
Explanation:
Parasitism is a kind of interaction between organisms in which only one organism gains from the interaction. Usually one organism gains at the expense of the other organism.
In this case, the cuckoo bird gains at the expense of the warbler bird. The cuckoo bird lays its eggs in the warbler bird nest and also tricks the warbler bird to care for its young at the expense of the warbler bird's young.
This is parasitism.
Answer:
Parasitism
Explanation:
This type of relationship is the brood parasitism, a clear example of the parasite-host relationship. Instead of building their own nest for their living, the cuckoo will lay their eggs in what is known as reed warbler’s nest. This leaves the warbler to take care of the egg together with her own children. When the eggs get hatched, the chick of the cuckoo will then ejects the young of the warbler from the next, which paves way for it to get all the food that its adopted mother will provide.

In a longitudinal wave, wavelength can be measured as the distance between
A. two adjacent compressions
B. a compression and the next resting place
C. both.
D. none of the above
Answer:
A. two adjacent compressions
Explanation:
A wave is transverse if the oscillations occur at a right angle (transverse) to the direction of wave propagation. This kind of wave creates characteristic hills and down. Transverse waves include all-natural electromagnetic waves, rope waves, water waves, waves generated by the marketing of taut wire.
A wave is longitudinal if the oscillations occur along (along) the direction of wave propagation. The longitudinal wave creates characteristic places of thickening and thinning of the environment. Longitudinal waves include:
sound wave, elastic wave, laser beam

Calculate by what percentage did the captive population of golden lion tamarins increase between 1970 and 2007?
Answer:
The captive population of golden lion tamarins increase between 1970 and 2007 is explained below in detail.
Explanation:
In the early 1970s, there were 91 lion tamarins in 27 distinctive zoos. Biologists created a strategy to improve the species' survival. The purpose was to improve the quantity and biogenetic variety of lion tamarins. As of 2007, there were 497 lion tamarins in 144 terrariums around the globe. Further, about 154 tamarins from the program have been re-presented to the wild since 1984. These tamarins are components of a strong wild population of more than 651.

what do oceanographers use echo-sounding devices to study?
Echo-sounding device are used by the oceanographers to study the distance and depth of the water to know how fast the sound waves travel.
What is an echo-sounding device?Echo sounding is the measure of the depths using sound waves. Echo- sounders use different frequencies of sound to find out the different things present in the seafloor. Scientists typically use echo-sounders which transmit sound at the frequency of 12 kiloHertz (kHz) to determine how far down the seafloor depth lies.
The sound waves through the device travels down through the water column until they hit the seafloor where they are reflected back up to the echo-sounder. By recording the time it takes for the sound to travel down to the seafloor level and back again, it is possible to calculate the depth of the water as we know how fast the sound travels.
