Which of the following is a type of water pollution caused by leaded gas, The production of some pesticides, and burning garbage? Algae
dioxins
mercury
pathogens
Answer:
Dioxins.
Explanation:
Dioxin is a type of water pollution caused by leaded gas, the production of some pesticides, and burning garbage.
What do you mean by Water pollution?Water pollution may be defined as any undesirable or contaminated substance presents in water bodies that definitely harms the life of aquatic organisms.
Dioxins are highly toxic to the environment as they are responsible for causing cancer, a threat to the immune system, etc.
They are persistent organic pollutants that take a long time in the degradation process which involves breakdown into simpler substances.
Therefore, Dioxin is a type of water pollution caused by leaded gas, the production of some pesticides, and burning garbage.

What are the horticultural advantages of producing plants by cuttings rather than from seeds? Can you think of any disadvantages?
.Propagating a plant by cuttings will allow you to keep the special characteristics of that plant. Plants grown from seed will often be different from the parent plant and from each other. Propagating a new plant via cuttings avoids the difficulties of propagating by seed.
Disadvantages of propagating stem cuttings are: You will get a lack of genetic diversity and you may potentially increase Insect and Disease weakness in the new plant.
A researcher is studying the plants and animals in a particular biome. The observations include ferns, large woody vines, monkeys, sloths, and boa constrictors. In which biome is the researcher located?
Tropical Rain Forest is the biome that include ferns, large woody vines, monkeys, sloths, and boa constrictors.
What is Tropical Rain Forest?Tropical rainforests are the rainforests that occur in the regions of tropical rainforest climate where there is no dry season. Due to such type of climate, there is greater amount of biodiversity.

Which drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract?.
Answer:
Anticholinergic drugs are common ingredients in antidiarrheal medications because they significantly decrease intestinal motility and secretions.
Anticholinergics drug class is used to slow the movement of gi contents, causing a decreased ability for muscles to contract.
What are anticholinergics?Anticholinergics are a type of medication which blocks the action of a neurotransmitter known acetylcholine. Acetylcholine transfers signals between cells that affect specific bodily functions. As anticholinergics can affect a variety of functions, including digestion, urination, salivation, they can help treat many conditions.
The medication blocks acetylcholine from causing involuntary muscle movements in the gastrointestinal tract, lungs, urinary tract, and other areas of the body.

If a strand of DNA has 48% cytosine what will the percent be for the other nitrogenous bases?
Answer:
There are 4 possible nucleotides that occur in two complementary sets. If 24% of the DNA is cytosin, the equal share has to be the complementary guanin. That makes 48% GC that leaves 52% AT, thus 26% are adenine and 26% thymine.
This calculation of course wouldn’t work if you were to look at only one DNA strand, where you’d end up with a vastly underdetermined mathematical system.

Answer:
Veins arteries and capillaries
The structures in the human body that carry out some of the same function as xylem and phloem are veins, arteries, and capillaries.
What do you mean by Xylem and Phloem?Xylem and phloem are the vascular tissues that transport water, minerals, and food from the roots to the leaves and from the leaves to the roots respectively.
Xylem and phloem represent homology with the veins and arteries. Veins carry blood back towards your heart, while arteries carry blood away from your heart.

In a multicellular organism, it is cell-to-cell communication that allows the trillions of cells to coordinate activities, including during development and regeneration. The three stages of cellular communication include: reception, transduction, and response. This study determined the key steps of a cell communication pathway involved in salamander limb regeneration. After amputation of a front salamander limb, the severed axons retract within the stump and grow back along the nerve sheath. To elucidate the molecular mechanisms, the researchers set up a series of controlled experiments to determine the events in salamander limb regeneration. Drag the general cell communication steps of the regeneration experiment into the correct order.
The process of amputation will interfere with the ability of cells to communicate with each other.
What is cell to cell communication?The body of whole multicellular organisms have a lot of cells which are differentiated hence they perform diverse functions. The essence of cell differentiation is to allow different cells to perform different functions.
The question is incomplete hence we can not give here the process of cell regeneration. However, we know that the process of amputation will interfere with the ability of cells to communicate with each other.

why was soil in wheat farms so much more vulnerable to erosion?
Explanation: The potential soil erosion increases if the soil has no or very little vegetative cover of plants/grass and/or crop residues. Plant and residue cover protects the soil from rain impact and splashes from it. It tends to slow down the movement of runoff water and allows excess surface water to infiltrate.
