What components do all cells have?

Answers

Answer:

Both animal and plant cells have these components: Cell membrane – this surrounds the cell and allows nutrients to enter and waste to leave it. Nucleus – this controls what happens in the cell. It contains DNA, the genetic information that cells need to grow and reproduce.

All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins.

#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

Answers

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.

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 " .

Which of these is not considered a potentially hazardous food?

Answers

Answer:

Packaged foods ( e.g. muffins, cookies or candies ) are not considered as a potentially hazardous food .

Explanation:

A potentially hazardous food is that food ( natural or man made ) which  supports the rapid and progressive growth of infectious and toxin - producing microorganism.                                                                                                               These foods are typically foods having high protein content or carbohydrate content , have high moisture content or low acidity .                                          Examples of potentially hazardous food includes meats,  eggs , cooked beans or peas ,cut fruits and vegetables , cooked vegetables, cooked rice , raw seeds and sprouts , etc.                                                                                              So , packaged foods are not considered as hazardous as they are packaged and so are protected from microbes as they  are not in contact of atmosphere . All the other foodstuff , even boiled food  is also hazardous as they provide necessary conditions required by microbes to grow like moisture, etc.

Identify the correct statement about bond formation between atoms:Required to answer. Single choice.

(1 Point)

It increases the energy and decreases stability

It decreases the energy and increases stability

It increases the energy and increases stability

It involves no change in energyose

Answers

Answer:

It decreases the energy and increases stability

Explanation:

When atoms come together, they chemically bond together to form molecules and compounds. The atoms form bonds by either sharing their valence electrons (covalent) or via the ionic charges of each atom.

The formation of bonds between atoms strengthen the molecule formed. This bond formation DECREASES THE ENERGY due to energy loss during the process but INCREASES THE STABILITY of the molecule. This means that atoms in a bond are MORE STABLE than single/individual atoms. However, bonds with higher orders are more stable than that with lower orders.

Forward possible reasons Sam owns and operates Floating Away, a beach concession business. She has five rental wagons located along a seven-mile stretch of a vacation beach. Each wagon rents floats, boogie boards, umbrellas, and lounge chairs by the hour or by the day. Customers walk to the wagon to inquire about rates and usually rent the items immediately. Sam prides herself on the way her employees interact with her customers in order to help make their vacation experience the most enjoyable and convenient it can be. For example, if someone rents an umbrella for the day, the wagon worker follows the customer to his or her desired location and sets it up. And at the end of the day, the worker retrieves the umbrella. Customers have appeared to be very satisfied with this arrangement, as evidenced by the profitability enjoyed by Sams business for the past several years. This year, however, a new competitor, J Js Floats, has opened up close to one of her wagons and has seriously impacted the profitability of that wagon. Sam realized that she needed to find a way to innovate and improve her offerings or run the risk of losing even more business to her competitor. Sam decided to survey her current customers to learn what her employees could do to make their rental experience even better. Using the comments they received, Sam and her employees worked together to develop a plan of action. They came up with several improvements based on customer responses. One change they made was in the length of time customers could rent the products. Customers indicated they wanted to have the rentals for their entire vacation period without having to come back each morning. Sam decided to add weekly rental prices and allow customers to keep the items in their hotel rooms, returning them at the end of the rental period. She also began setting up umbrellas and chairs along the beach each morning ahead of the crowd with signs hanging on them saying, Have a seat, the rental attendant will be right along to help you with rental prices attached. This made her rentals much more convenient for the customers. With these adjustments, her profits returned to record-high levels, and Sam appears to have thwarted the threat of her new competitorat least for the time being.Put the steps of the process in the correct sequenceCustomers approach the rental wagon to inquire about rates and rent the items.Asking current customers what would make their rental experience better.Floats, boogey boards, umbrellas, and lounge chairs.Satisfied customers.Customers' great vacation experience.Employee brings umbrella to the customer's location and sets it up.Sam's profitability returns to record-high levels.Employees' helpful and friendly attitude.Transformational Processes Feedback Input Output why is 0.65 bigger than 3/5?
