Normally, climatic conditions become colder as altitude increases. “Life zones” on a high mountain reflect the changes, plants at the base are the same as those in surrounding countryside, but no trees at all can grow above the timberline. Snow crowns the highest elevations.

There are 3 major wind patterns found in the Northern Hemisphere and also 3 in the Southern Hemisphere. These are average conditions and do not essentially reveal conditions on a particular day. As seasons change, the wind patterns shift north or south. So does the inter-tropical convergence zone, which moves back and forth across the Equator. Sailors called this zone the doldrums because its winds are normally weak.

Answer:

The factors that influence the weather conditions are as follows-

(1) Latitude- The latitude plays an important role in the occurrence of a weather condition. The higher latitudinal areas experience colder weather compared to the low latitudinal areas. It is because the temperature is maximum at the equator and minimum at the poles.

(2) Elevation- The air molecules are comparatively dense and thick near the ground surface. As a result of which the temperature and pressure is maximum at or near the ground surface, but at the higher altitudes, these air molecules are loosely dense, so the temperature remains relatively cold. Thus, higher elevated areas experience a cold weather pattern and low elevated areas experience warm weather.

(3) Temperature- The temperature at the equatorial region is comparatively higher than the places away from the equator. It is because the earth receives the maximum amount of sunlight in this region.

(4) Wind- The wind blows from a region of high pressure to low pressure. In a low-pressure zone, rainfall occurs. This prevailing wind in an area controls the climatic condition.

The meteorologists are able to predict the occurrence of different weather types in any particular area by using various instruments such as-

(a) Thermometers- It is used to measure the air temperature in any particular area

(b) Barometers- It is a device that is widely used to measure the air pressure.

(c) Anemometers- It is used to measure the wind speed occurring in an area.

Scientists are examining the possible role of a large asteroid in the Cretaceous mass extinction event. A large asteroid strike

QveST [7]

Answer:

Option C

Explanation:

The null hypothesis is the problem statement and alternative hypothesis is counter of the null hypothesis.

Hence, the null hypothesis here is the rate of extinction was neither higher nor lower when there were sudden climatic changes (asteroid strike)

And alternate hypothesis is "the rate of extinction was either higher or lower when there were sudden climatic changes (asteroid strike)"

Hence, option C is correct

What are the advantages of having perforated walls among the vessel elements?

Brilliant_brown [7]

Answer:

It allows rapid conduction of water from one vessel element to the next.

Explanation:

Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.

The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.

Which of the following products of the light reactions of photosynthesis is consumed during the Calvin cycle? A) oxygen B) water

IrinaK [193]

Answer:

NADPH

Explanation:

Light-dependent reactions form the NADPH when the electrons from the water molecule are passed from PS II to PS I and finally to the NADP+. The enzyme NADP reductase catalyzes the reduction of NADP+ into NADPH. The enzyme is located on the stromal side of the thylakoid membranes and therefore, the NADPH is released into the stroma. Stroma is the site for the reaction of the Calvin cycle. During the Calvin cycle, the reduction of 3-phosphoglycerate into glyceraldehyde 3-phosphate uses NADPH as the electron donor.
