When you work in a School Lunch program, you’re bound to face challenges that pop up seemingly out of nowhere. That’s just the nature of serving hundreds or even thousands of students each day.

But, when you keep encountering the same Child Nutrition program problems, over and over, day after day, it’s likely more than just a coincidence.

Instead, there probably are bigger issues causing these problems.

The bad news is that it often can be unclear what these bigger issues are, which makes fixing them almost impossible.

The good news? We at Harris School Nutrition Solutions have spent thirty years working with the men and women of Child Nutrition programs all across the U.S., helping to diagnose and solve their School Lunch problems.

So, we figured we’d share with you some of the common school lunch-line challenges we’ve seen over the years, the real issues behind those challenges, and of course the solutions to both.

Which of these is not a human cause of extinction of species?
Choose the correct answer.


A) Clearing of an area for farmland.

B) A dam built in a river for city water usage.

C) Competition for food resources with another native species.

D) The introduction of a new predatory species to an island by boat.

Answers

The answer is A
_____________

The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

What is species?

Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.

In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.

But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.

Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.

likely consequence of this increased industrialization?

O a decrease in the amount of water pollution

O an increase in the amount of water available for recreational use

an increase in the destruction of natural food webs

O a decrease int he amount of water needed by industry

Answers

Answer:

The correct answer would be - an increase in the destruction of natural food webs.

Explanation:

Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.

The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.

Los paramecios (género Paramecium) son protozoarios, es decir, organismos microscópicos del reino protista. Un paramecio es un organismo unicelular que puede llevar a cabo todas las funciones esenciales de un modo funcionalmente similar a una célula animal. Los paramecios pueden reproducirse tanto de manera sexual como asexual (bipartición). Estos organismos viven en cuerpos de agua dulce rica en nutrientes orgánicos como estanques, charcos, regiones de ríos parcialmente estancadas, etc. En estos ambientes los paramecios se reproducen de un modo óptimo a una temperatura entre 24 °C y 28 °C, donde pueden llegar a dividirse hasta 4 veces al día.

Answers

Answer:

the answer is A before cell division (mitosis or meiosis)

Explanation:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
