The optimal light level for photosynthesis is 10,000 Lux. Lux is a unit for measuring light intensity. Low light intensity tends to lower rate of photosynthesis. However after reaching an intensity of 10,000 Lux, there is no increase in the rate. Carbon dioxide concentration in the atmosphere ranges from 0.03 to 0.04 %. It has however been determined that 0.1% of carbon dioxide in the atmosphere significantly increases the rate of photosynthesis . Therefore supplementing CO2 to the existing amount will speed up photosynthesis and plant growth rate will increase.

Len [333]

Answer:

Explanation below.

Explanation:

3. The salinity of water increases as the water moves from the inland area to the ocean. This is because the ocean has high salinity.

Salinity is the amount or concentration of salt in the water.

WAYS BY WHICH ESTUARIES PROTECT THE INLAND AREAS

1. The plant in estuaries prevent shoreline erosion.

2. Protect the inland areas from flooding.

3. Protect the inland areas from storm surges from hurricane.

IMPORTANCE OF ESTUARIES TO INLAND PEOPLE AND WILDLIFE.

1. They provide nesting and feeding habits for many aquatic plants and animals.

2. Provide goals and services that are economically and ecologically indispensable.

3. Prevent shoreline erosion

4. Protect the inland areas from flooding.

Answer:

1. when there is cardiovascular disease.

2. High blood pressure increases the likelihood of suffering a stroke, a heart attack, heart failure, kidney disease or premature death.

3. The mitral valve opens.

Explanation:

1. High blood pressure is a common condition in which the force exerted by blood against the walls of the arteries over the course of time is high enough to cause you health problems such as heart disease. After the first rise of pressure caused cardiac ejection volume, one notch occurs with a second ascent product of the reflection of the pulse wave. In younger individuals, with elastic arteries, said wave occurs in diastole, so does not influence the peak systolic pressure. By contrast, with advancing age and the stiffness of large vessels, the reflected wave is transmitted prior to the aorta (systole) so as to increase the peak central PAS.

2. The pressure increases progressively the pressure of the blood flowing through the arteries. As a result, you can submit the following: Arteries damaged and narrowed. High blood pressure can damage the cells of the inner lining of the arteries.

3. When the pressure in the left ventricle falls below the pressure of the left atrium, the mitral valve opens, and the left ventricle fills with blood that had been accumulating in the left atrium.

Does the scientific method steps always have to be in the same order? If not, why?

Ierofanga [76]

Answer: The steps may not always be completed in the same order. Following the four steps, the results of the experiment will either support the hypothesis or will not support the hypothesis. Scientists are always free to change or write a new hypothesis and start the four steps all over again.

I really hope that helps

Plates slide past - transform faults
Plates collide and crumple - mountains
Creation of Hawaiian - volcanoes
One plate sinks - subduction
Plates spread apart -mid ocean ridges

I think this is right :)
