Answer:

The process shown in the model requires energy from the cell.

Explanation:

Active transport refers to the movement of materials across the cell membrane against concentration gradient.

The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.

What is the correct way to analyze a term that means "softening of the cartilage"?
Ber [7]

Chondromalacia is the synonymous of the cartilage softening (chondro = cartilage, malacia = soft). It's a pathology of softening affecting the joints and more particularly those of the knee (kneecap and femur).

This anomaly can be observed in several circumstances:

• the first is that of direct trauma. It is the cartilaginous lesion occurring before the fracture (fissure) of the cartilage.

• the second is that of common osteoarthritis. It is highly likely that the first stage of osteoarthritis begins with edema (swelling of the cartilage or closed chondropathy) that makes the cartilage less resistant and more vulnerable; this soft cartilage can then crack on its surface (open chondropathy) and these cracks will be more difficult to heal.

Physiological factors such as ____________ , water levels, and ph must remain within a certain ____________ for cells and organi
Monica [59]

For an organism to function properly all the physiological factors should be favorable. These physiological factors include water level, pH, temperature etc. To perform the basic function of the life, it is important to maintain the physiological parameter in a particular range.  

In case, these physiological parameters are not balanced, then the body of the organism does not perform well and causes illness.  

So, the first blank can be filled with temperature and the second blank can be filled with range.

You are examining a field of crop plants and notice that many of the leaves have small scattered necrotic spots on them, but non
Thepotemich [5.8K]

Answer:

Avirulent.

Explanation:

VIRULENCE is the ability of a pathogenic organism  to infects the host, leading to damages  or death of the host. The extent of these virulent effect depends on  certain chemical substances ( called Virulence factors) produced during the  pathogenic processes.

The virulence effects  is achieved  due to the ability of the virulent factor to disrupt the entire physiological mechanisms of  the organisms; e,g crop plants; though  suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.

In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because

none of the d crop pant is completely diseased.

the nascent intenodes and leaves  are growing to usual size.

Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.
