Answer:

3. Household wastes

2. Landfills

1. Agriculture

Explanation:

The groundwater is more and more contaminated, and there are numerous ways in which the contamination occurs. The causes of pollution mainly come from the human activities. The humans use all sorts of chemicals, fossil fuels, paints, and often there is waste from them, waste that is dumped into the drainage, and occasionally reaches the groundwater. The leaking of linings also manages to cause lot of damage, as very often it can reach the groundwater, causing heavily contamination of it. The agriculture, as much as it is needed, is a big polluter too, and the pollution mainly comes from the usage of pesticides, herbicides, and fungicides, which wash through the soil and end up in the groundwater.

Barnacles attach to shellfish for transportation. The shellfish is not helped or harmed. This is an example of_

Vesna [10]

The correct answer is:

_________________________________________________

→ " commensalism" .

_________________________________________________

<u>Note</u>: "Commensalism" refers to a symbiotic relationship {"symbiosis"} between two (2) organisms — in which one organism benefits and the other organism is neither helped nor harmed.

{ i.e. " +, 0 " ; that is: "plus" sign for "one organism benefits" ;

"zero" sign for "neutral" ;

(in that the other organism is neither helped nor harmed.}.

_________________________________________________

In the example given in the question, the two (2) organisms are:

1) the barnacles; and: 2) the shellfish.

The barnacles benefits by given a place to attach for the purpose of transportation (by using the shellfish to "cling to"}.

The shellfish are neither helped (benefitted in anyways from the attachment from the barnacles— nor are the shellfish harmed in any way.

What is the relationship between evidence, conclusions and theories.will mark brainliest

Pie

Answer:

They are inter-related with each other.

Explanation:

There is a great relationship present between evidence, conclusions and theories because evidences are those materials due to which a hypothesis can be verified and we can draw conclusion. When we repeat the same experiment and find out the same conclusion so it becomes theory and when these theories can't change with the passage of time, it becomes law. So evidence, conclusions and theories are inter-related to each other.

What are Constant/control variables

Alik [6]

Answer:

constant = changes and control is used as the basis of comparison

Explanation:

Constant variables are variables that do not change

e.g such as the temperature ( if it's meant to be kept at a constant temp).

Control variables are meant to be kept constant to allow for a comparison and thus determine the effect of IV (independant variable) and DV ( dependant variable)

All of the following except __________ developed in some vascular plants and are not present in any nonvascular plants.All of th

dem82 [27]

Answer:

Vascular plants have separate tubular tissues such as xylem, phloem for smooth transport of water, minerals and food while non-vascular plants do not show these attributes.

Explanation:

Although both life cycles are divided between the sporophytic and gametophytic generations, vascular plants have a dominant diploid sporophytic phase while non-vascular plants have a dominant haploid gametophytic phase.

Non-vascular plants are poikilohydric (they can withstand dehydration and can recover without any damage to their tissues), though they cannot control the water level in their cells and tissues. On the other hand, vascular plants are homoiohydry. They can survive in any habitat and can control the water content in cells and tissues, though they have low capacity to survive dessication compared to the non-vascular plants.

Non-vascular plants do not have true leaf. The leaves are mere chlorophyll containing. Photosynthesized food are directly sent from one cell to the other. They lack proper transport mechanism for food and water.

On the other hand, the vascular plants have complex multilayered leaf (cells) structure. The waxy layer cuticles on the leaves prevent dessication. That are more chlorophyll containing than their counterpart.
