with reference to evolution of long neck in giraffe explain how natural selection brings about adaptation of species to its environment

Answers

Answer 1

Answer:

Explanation:

In order to reach specific items of food that meet the dietary needs of the giraffe, they must reach for food up in the trees. Giraffes with longer necks are open to a wider array of food whereas the short necked giraffes are limited. The longer neck is seen to be more favorable. When a trait is more favorable, it has a higher likelihood of being passed on. The less favorable traits are eliminated or "weed" out and the taller giraffes mate with other tall giraffes, generating a greater population with this trait. Again, it is solely dependent on what is available around them and their surroundings.

Do you know the different stages through which raw agricultural materials go before they reach your table? Trace the journey of a burger bun from grains of wheat at a farm to your table. Perform online or offline research and write a report on the processes involved in manufacturing burger buns.

Answers

PLATO ANSWER

The basic raw material for making a burger bun is flour. The major steps required for turning wheat into a burger bun are as follows:

Cultivation of wheat

Harvesting of wheat

Grinding wheat to flour

Baking flour to make buns

Let’s trace the journey.

Before a burger bun reaches the table, it goes through several processes. The farmer select wheat heads when they turn golden yellow and the kernels are hard and dry. A combine harvests the wheat and packs it in sacks. The farmer then stores the wheat in a granary and eventually sells it to a wholesale trading company. The wholesaler transports the wheat to a warehouse and then sells it to a flour manufacturer. The manufacturer`s first step is to cleanse the wheat of impurities, such as weeds, seeds, dirt, small stones, and metal pieces, by using a series of giant disks and magnets. The kernels then go through a giant bath, which separates any other heavy particles that remain. It also helps cleanse the grains. Lighter materials such as husks or flakes of stalk will wash away.

After the cleaning process, the wheat goes through rollers that crack the kernel, and then huge machines use various screens to filter the wheat pieces. In the production of white flour, air currents blow the bran away from the rest of the wheat, and then the remaining pieces of wheat go through a variety of rollers that grind it into finer powder. After each grinding, the machines sift the wheat through screens—and there are more than 20 such screens. Each screen filters finer and finer particles. Finally, the manufacturer fortifies the wheat by adding special ingredients such as vitamins and iron. The manufacturer then packs, labels, and stores the ready-to-bake flour for transportation and supply.

The packaged wheat flour reaches the store racks through a variety of distributors and suppliers and by various means of transport. Once on the shelf, it is a matter of time before a consumer purchases it. Some of the packaged products may reach industrial baking organizations.

After bringing home some flour, I unpack it and then mix it with salt, water, yeast, and a few other ingredients. Before rolling it, I have to give the dough some time to rise. The yeast in the dough makes it rise through the action of tiny bubbles of carbon dioxide. I then form the dough into the correct shapes and put in the oven to bake. In the baking process, the gas bubbles exit the dough, leaving the bread soft and fluffy. After baking and cooling, the buns are ready to become parts of mouth-watering burgers.

How might Kangaroo population suddenly increase? How might this affect the ecosystem?

Answers

Answer:

The kangaroo population could suddenly increase if the predator of the kangaroo found something else to hunt, or started to go extinct. If this were to happen, then the prey of the kangaroo would most likely go extinct due to the sudden rise in population of the kangaroo. If there were more kangaroo, then there would be less of whatever the kangaroo ate, then the prey of whatever the kangaroo ate would suddenly increase, it goes all the way down the chain.

Does budding use mitosis

Answers

Answer:yes

Explanation:

because it does

Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism.
Diploid cells of brewer’s yeast look, grow, and asexual reproduce by a type of mitosis called budding. The bud is cut off from the parental cell, and both new cells, begin the cell cycle all over again. Both haploid and diploid yeast cells grow and reproduce this way.

Answers

Answer:

yes

there mammals so they need to have sexual reproduction compared to fish they dont need sexual reproductions to have a organism (baby)

Explanation:

Yes, the animals like wolves and lions reproduce by se-xual reproduction.

Se-xual reproduction in mammals:

The process of production of offspring by combining genetic components from two individuals of different se-xes, that is, male and female is termed se-xual reproduction. In higher animals like mammals, that is, lions and wolves, the process of se-xual reproduction takes place.

The mammals generate gametes, that is, egg and sperm via the process of meiosis in gonads, that is, ovaries in females and testes in males. The production of eggs takes place by the process of oo-genesis, and the production of sperm takes place by sperma-togenesis.

Afterwards the fusion of male and female gametes takes place, that is, the process of fertilization occurs and generate a diploid zygote.

Thus, the given statement is true.

Negative pressure rooms are sometimes referred to as source isolation rooms, while positive pressure rooms are sometime called protective isolation rooms. Explain the thinking behind these names.

Answers

Answer:

Negative pressure rooms are sometimes referred to as source isolation rooms because they prevent potentially contaminated air to exit the room.

Positive pressure rooms are also known as protective isolation rooms because they prevent the entering of any pathogen in the air to the room where a patient with a compromised immune system is staying.

Explanation:

Negative pressure rooms or source isolation rooms have lower pressure than the outside. Due to this pressure difference, air can enter the place but can not leave it, trapping the pathogens. Patients with infectious conditions are in these rooms to prevent the spreading of the disease. That is why they are also called source isolation rooms. These rooms have a  system that filtrates and circulates the air.

On the other hand, in positive pressure rooms, the air pressure is higher. As a result, the air, with any potential bacteria, virus, or particles, leaves the room to keep the patient safe. They are also known as protective isolation rooms because patients with a compromised immune system are there to protect them from any pathogens in the air.

It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.

The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions.  The higher the electron affinity is, the more the neutral atom wants to gain electrons.  The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell.  That means that they want to form cations (loose electrons).  Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration.  That means that it forms anions.
