Each lung has an oblique fissure, with a transverse fissure further dividing the right lung. The superior and inferior lobes of the left lung are divided by an oblique fissure. The superior, middle, and inferior lobes of the lungs are separated by an oblique and horizontal fissure. As a result, the left lung has two lobes whereas the right has three.
A lobar bronchus supplies each lobe. Bronchopulmonary segments that are supplied by segmental bronchi divide the lobes.

Why does the Department of Homeland Security target foot-and-mouth disease?
The bottom- and- mouth complaint contagion has been honored since at least the 16th century.
It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint. With one in nine Americans employed in the husbandry or confederated diligence, the goods of an FMD outbreak in the U.S. would be ruinous – estimated at nearly$ 200 billion in lost profit over 10 times across affected diligence.
Therefore the Department of Homeland Security target foot-and-mouth disease.

Which choice best summarizes the outcome of Redi‘s experiment?
Francesco Redi performed his experiment against the theory of spontaneous generation. In his experiment, he takes one glass jar and a piece of flesh and analyzes them in three different situations.
Why did Francesco Redi perform his glass jar experiment?Francesco Redi performed his glass jar experiment in order to illustrate the evidence against the theory of spontaneous generation.
He demonstrate that dead maggots or flies would not generate new flies when positioned on rotting flesh in a sealed jar, whereas live maggots or flies would have the capability to grow some eggs of maggots.
This experiment discredited both the presence of some essential components in once-living organisms and the requirement of fresh air to induce living life.
The complete question is as follows:
Which choice best summarizes the outcome of Redi‘s experiment?

Answer and Explanation:
FALSE
Personal boats and watercraft DO contribute to ocean pollution.
Most water vehicles need fuel to be powered and go through the water. This fuel can sometimes go into the water, polluting the surrounding area.
Watercraft that don't use fuel, but instead are man-powered, can still contribute to ocean pollution. People can bring items such as soda cans, beer bottles, fishing equipment, etc., and any of these items tend to be discarded into the water, leading to pollution and degradation of the ecosystem, harming any wildlife that lives there.

Where are chromosomes located during metaphase?
The mitotic spindle pulls the chromosomes together at the metaphase plate. Microtubules from opposite spindle poles grab the two sister chromatids of each chromosome. In metaphase, the spindle has collected all the chromosomes and lined them up at the middle of the cell, ready to divide.
What are chromosomes?Chromosomes are the greatest level of DNA and protein organization. Chromosomes' primary job is to transport DNA and genetic information from parents to offspring. During cell division, chromosomes play a vital role. They keep DNA from becoming twisted or damaged.
The metaphase plate is a plane or region that is about equidistant from a dividing cell's two poles.
