Which seed plants are not gymnosperms?A. cycads
B. ginkgo
C. flowering plants
D. conifers

Answers

Answer:

Flowering plants (Ans. C)

Explanation:

Gymnosperms are the non-flowering plants and produce seeds that are not enclosed within an ovary. they contain their seeds on the surface of the leaves and open to the air which is directly fertilized with the help of fertilization.

Gymnosperms include:

1) Cycads (division Cycadophyta): These are woody trunks, evergreen compound leaves. The example includes cycas.

2) Conifers (division Pinophyta): Theses are woody, cone-bearing shrubs and tissues with vascular tissues. Examples include Pines, Redwoods, Cedars. etc.

3) Ginkgo biloba (division Gynkgophyta):These are a cylinder, large and fan-shaped leaves. The example is Ginkgo biloba.

So, the flowering plants are not included in gymnosperms.

Conifers

Which of the following is an example of gene flow?

Answers

When the genes propagate from one area to another.
The founder effect happens when genetic diversity declines due to an external larger group of organism invades a set of current living population. An example of this process is when the British colonies invaded the Mesoamerican continent where native americans lived and were outrun by the British colones, especially since many wars were made and ethnic cleansing.

Which term describes a pure substance that is made up of only one type of atom?1)matter
2)rock
3)compound
4)element

Answers

ELEMENT

A pure substance is one that is composed of only one type of material.

This material may not necessarily be made from only one type of element, but can be composed from different elements yet be pure. An example of this is water. Water is made up of oxygen and hydrogen. Water that is free of contamination is termed as pure.

Examples of pure substances are:

1.Gold

2. Iron

3. Carbon

4. Sugar

5. Nitrogen gas

6. Oxygen gas

7. Salt

Element describes a pure substance that is made up of only one type of atom. Elements cannot be broken down into more simpler substances. There have been 118 elements discovered by scientists so far.

As the human population grows, what happens to our natural-resource requirements?a.They increase.
b.They decrease.
c.They do not change.
d.They go in cycles.

Answers

As the human population grow, the natural resource requirements INCREASES. The correct option is A.
More than ever before, the number of people that are living on the earth has increased tremendously and this has put a great pressure on the basic materials that are needed by humans, one of these is natural resources.
Human natural resources requirement refers to the amount of natural resources that is adequate for human's use. There are many natural resources, which man use for different purposes. Most of these resource are already diminishing yet the population of man keep increasing. Thus, man need more natural resources.

The correct answer is A) They increase

The most easily polluted groundwater reservoirs are A. sewage plant reservoirs.
B. water-table aquifers.
C. salt reservoirs.
D. artesian wells.

Answers

The right option is B. water-table aquifers

Water-table aquifers are underground layer of water whose water table is at atmospheric pressure and is not below a confining layer. Water-table aquifers are susceptible to drought conditions and pollutants because they are usually closer to the earth's surface. Water-table aquifers can be polluted by naturally occurring mineral and metallic deposits in rock and soil, manufactured chemicals such as fertilizers, and dumps or landfills. When ground water pollutants reach a water-table aquifer, they make the water unclean and unusable for decades.

Water-table aquifers

Further Explanation:

Water-table aquifers are more susceptible to pollution. The water table is the specific part of groundwater, whereas aquifers are the entire portion of groundwater of an area. Aquifers are a large storehouse of water-bearing rocks, gravel, sand, and silt. The water content of the aquifers keeps on changing with seasons. Three different types of water aquifers are present, which are confined, unconfined, and semi-confined.

The groundwater resources are more prone to pollution due to agricultural waste, landfills, hazardous chemicals, and atmospheric pollutants. Human activities are responsible for groundwater pollution. The chemicals and toxic waste can be accidentally or intentionally released in the groundwater. The porosity and permeability of soil allow the contaminants to reach with an ease to aquifers. The pollutants can move to the underground through the root system and animal burrows also. If any river or stream is present nearby the contaminated groundwater, then the risk of river contamination is very high. Some naturally occurring substances like decaying organic matter moves towards the groundwater and change the taste, color, and odor of the water.
