Answer:

The correct option is A.

Explanation:

Atherosclerosis: It is defined as a disease in which due to build up of plaque the inside of an artery narrows. In initial stage of this disease generally no symptoms occurs, in severe condition it can cause kidney problems, stroke, build up of cholesterols in the walls of large arteries, peripheral artery and coronary diseases.

Cause of Atherosclerosis is unknown, but risk factors include high blood pressure, diabetes, smoking, abnormal cholesterol levels, unhealthy diet, and obesity.

In order for an statonary object to move, an unbalnced force must act upon it.<br> True<br> False
Alenkinab [10]

Answer:

true

Explanation:

any force can be added to make a stationary object move. but if it was balanced then it would just stay in position

if there is 100N of force going towards the object, and you are pushing the object with 100N force. It  will not move.

Which prediction will most likely describe how friction will affect her findings? The distance for Trial 3 will be greater than
Juliette [100K]

The complete question is :

Charlie is investigating friction. She will use the same amount of force to push two wooden balls across two level surfaces. Then she will record her results in the table below.

Which prediction will most likely describe how friction will affect her findings?

Answer:

The distance for Trial 3 will be greater than the distance for Trial 4 because the difference in surface roughness will affect friction.

Explanation:

The frictional force depends greatly on the roughness of the body surfaces. It acts opposite to the direction of motion when two body surfaces have a relative motion between them.

In the context, equal mount of force is applied to push the wooden balls. So the net force which acts on the balls are :

F' = F - f

Here, F = the force applied

         f = force of friction

And f = μ.N (N = reaction force)

Here μ is the coefficient of friction that depends on the surface roughness. The frictional force will be less when the surfaces are smooth. Thus for the trails 3 and trial 4, the distance for trail 3 would be greater than trail 4 as the surface is polished and would offer less friction.

HELP!!! choose one of the following types of biotechnology: genetic engineering, cloning, or artificial selection. You will then
Darina [25.2K]

Answer:

Genetically modified organisms or GMOs can be characterized as living beings (for example plants, creatures or microorganisms) in which the hereditary material (DNA) has been changed in a way that doesn't happen normally by mating and additionally common recombination. The innovation is regularly called "present day biotechnology" or "quality innovation", now and again likewise "recombinant DNA innovation" or "hereditary designing". It permits chosen singular qualities to be moved from one life form into another, likewise between nonrelated species. Nourishments created from or utilizing GM life forms are regularly alluded to as GM nourishments.  

GM nourishments are created – and promoted – in light of the fact that there is some apparent bit of leeway either to the maker or customer of these nourishments. This is intended to convert into an item with a lower cost, more prominent advantage (regarding toughness or healthy benefit) or both. At first GM seed engineers needed their items to be acknowledged by makers and have focused on advancements that carry direct advantage to ranchers (and the food business by and large).  

One of the destinations for creating plants dependent on GM life forms is to improve crop insurance. The GM crops as of now available are fundamentally focused on an expanded degree of harvest security through the presentation of obstruction against plant infections brought about by creepy crawlies or infections or through expanded resilience towards herbicides.  

Resistance for insects is accomplished by consolidating into the food plant the quality for toxins creation from the bacterium Bacillus thuringiensis (Bt). This poison is presently utilized as an ordinary bug spray in agribusiness and is ok for human utilization. GM crops that inalienably produce this poison have been appeared to require lower amounts of bug sprays in explicit circumstances, for example where nuisance pressure is high. Infection obstruction is accomplished through the presentation of quality from certain infections that cause sickness in plants. Infection opposition makes plants less helpless to sicknesses brought about by such infections, bringing about higher harvest yields.  

Herbicide resilience is accomplished through the presentation of a quality from a bacterium passing on protection from certain herbicides. In circumstances where weed pressure is high, the utilization of such harvests has brought about a decrease in the amount of the herbicides utilized.
