Sloan [31]

Answer:

Some practices from the recommended list of physical/cultural control that you could do year-round to help control pests are as follow:

1. We can use those plant species that are more competitive. These plant species include release of chemical toxins that suppress other plants and insects.

2. Use of large Hight quality seeds.

3. By using narrow spacing in row and increasing seeding rate.

4. By using shallow seeding technique which allow desired plant species to grow and develop faster above the surface of soil.

5. By ensuring that our plant species is perfectly placed in that growing environment which is optimized with every specs.

6. By rotating the crops

7. By rotating plant species with different growing cycles and seasonal cycles.

8. By rotating herbicides with alternative modes of action to delay the herbicide resistance development.

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.

What is the relationship between ligaments, bones and joints?​
kakasveta [241]

Ligaments connect one bone to another bone. Therefore, they allow a joint to form, because joints are where two or more bones connect.

Take your knee joint for instance (***see attached pic***). The knee joint is formed by the connection of the femur (your thigh bone), the tibia (your shin bone), and the fibula (the other long bone in your lower leg). In order for all of these bones to connect there are many ligaments in the knee joint that keep the bones connected and in place.  A well known example of one of these ligaments in the knee joint is the ACL (anterior crucate ligament), which is commonly torn in sports, namely football. Most people have heard of this ligament because it receives a lot of media attention since tearing it can greatly alter or even end professional athletes' careers.

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a per
olganol [36]

Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.

<h3>Veins</h3>

All over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.

Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
