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.

If organisms are of the same species, _____.

Nitella [24]

Answer:

The correct answer will be options-

1. they share genetic similarities

2. they can interbreed

3. they fall under the same genus

Explanation:

The taxonomic studies help the organism to identify, nomenclature and classification of the organism.

The classification system helps organize the organisms into several groups based on the similarity of the morphological characters. The species is the lowest group of the system which contains the organism which is reproductively isolated from the other group of organism.

If two organism is found to be of the same species shows that they share the same gene pool, belongs to the same genus and they can interbreed.

Thus, the selected options are the correct answer.

1. In the table below, identify each invertebrate by matching it with its characteristics.

erastovalidia [21]

Correct matching of invertebrates and its characteristics are as follows:

Sponges are animals which have many cell but no mouth, muscles , heart or brain. They are sessile and can not move from place to place like other animals do, filter feeding animals with an asymmetrical body plan.

Cnidarians are the animals with radial symmetry and stinging cnidocyte cells. These animals consists a special cell cnida which functions in preying catch and defense. example- jellyfish, anemone.

Flatworms are the worm like animal which do not consist a body cavity or coelom. example- fluke and tapeworms.

Roundworms or threadworms are segmented worms that can live in water or land. They consist a body cavity and internal organs. examples- pinworms and hookworms.

Mollusks are the animals which consist mentle, foot and and sometimes a shell. example- octopus, squids.

Echinoderms are the animals which have radial symmetry and an endoskeleton made out of calcareous plate. These animals live only in marine environment.These animals lack circulatory and excretory systems.

Arthopods are the animals with jointed legs and an exoskeleton made out of chitin. example- spiders, shrimps and crabs.

In the Florida map shown below, use the law of superposition to determine which rocks are oldest? Map of Florida identifying fou

tatiyna

Answer:

The answer is A

Explanation:

You can tell that rocks are older or younger depending on if other layers overlap. B is the oldest because all the others cover it, C is the second youngest because D and A overlap it. From what I could tell, when I took the test, it was either A or D, neither overlap each other so I was not sure so I guessed A and got it right. Though it could be looked at that A is smaller than D since its still growing and building.
