Explain how interactions can be both beneficial and harmful to the organism in a community

Answers

Answer 1

Answer: Interactions to an organism can be both harmful and beneficial due to the organism's circumstances. For example by adding tadpoles to an eco system it results in the tadpoles eating all the food thus killing the other organisms. Whereas by adding plants to an ecosystem it provides shelter for the organisms and possibly food being beneficial.

Answer 2

Answer:

An ecological community consists of all the populations of all the different species that live together in a particular area.

Interactions between different species in a community are called interspecific interactions.

The main types of interspecific interactions include competition, predation, mutualism, commensalism, and parasitism.

Symbiosis

Symbiosis occur when two species live together in a long-term, intimate association. In everyday life, we sometimes use the term symbiosis to mean a relationship that benefits both parties

Parasitism

It involves two species have a close, lasting interaction that is beneficial to one, the parasite, and harmful to the other, the host.

Commensalism

In a commensalism, two species have a long-term interaction that is beneficial to one and has no positive or negative effect on the other. For instance, many of the bacteria that inhabit our bodies seem to have a commensal relationship with us. They benefit by getting shelter and nutrients and have no obvious helpful or harmful effect on us.

Mutualism

In a mutualism, two species have a long-term interaction that is beneficial to both of them. For example, some types of fungi form mutualistic associations with plant roots. The plant can photosynthesize, and it provides the fungus with fixed carbon in the form of sugars and other organic molecules

Predation

In predation, a member of one species—the predator—eats part or all of the living, or recently living, body of another organism—the prey. This interaction is beneficial for the predator, but harmful for the prey. Predation may involve two animal species, but it can also involve an animal or insect consuming part of a plant, a special case of predation known as herbivory

What are the formal charges of both chlorines and iodine in icl2?

Answers

Answer:

Explanation:

Formal charge of ICl₂⁻

Formal charge = group no - ( no of non bonding electrons +no of bonds)

In I there are 7 electrons in outermost orbit . If we add one more electrons due to - ve charge on the ion , it becomes eight . This centrally placed iodine forms two single bond with two chlorine atoms on either side.

Each of chlorine atoms also contains 7 valance electrons like iodine.

So formal charge of chlorine

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 6 + 1 )

= 0

So formal charge of iodine

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 5 + 2 )

Formal charge of ICl₂⁺

In this case , central iodine will have only 6 valence electrons due to absence one electron.

So formal charge of chlorine in ICl₂⁺

= group no - ( no of non bonding electrons +no of bonds)

= 7 - ( 6 + 1 )

= 0

formal charge of iodine in in ICl₂⁺

7 - ( 4 + 2)

= 1

Find the [H+] in an acetic acid solution that has a pH of 5.12

Answers

Data:
pH = 5.2
[H+] = ?

Knowing that: (Equation to find the pH of a solution)
$pH = -log[H+]$

Solving:
$pH = -log[H+]$
$5.2 = - log [H+]$
Knowing that the exponential is the opposite operation of the logarithm, then we have:
$[H+] = 10^(-5.2)$
$\boxed{\boxed{[H+] = 6.30*10^(-6)}}\end{array}}\qquad\quad\checkmark$

What do you wrap your sandwich in? (pun, answer must be from the periodic table)

Answers

Final answer:

You can wrap your sandwich in Tin, an element from the periodic table.

Explanation:

The periodic table is a chart that organizes all known elements based on their atomic number, symbol, and atomic mass. To wrap a sandwich, you can use the element Tin, which has the atomic symbol Sn and atomic number 50. Tin is a soft, malleable metal that is often used as a coating for other metals to prevent corrosion. It can be melted and shaped into thin sheets, making it suitable for wrapping a sandwich.

Final answer:

The pun answer to the question 'what do you wrap your sandwich in?' is 'Aluminum', because aluminum is an element from the periodic table and aluminum foil is often used to wrap sandwiches.

Explanation:

The pun in this question refers to an element from the periodic table to humorously answer the question "What do you wrap your sandwich in?". One possible response could be: "You wrap your sandwich in Aluminum", since the word "wrap" is commonly associated with aluminum foil, which is used to wrap and protect food, like a sandwich. Aluminium is a chemical element in the periodic table with the symbol Al and atomic number 13. It's a silvery-white, soft, non-magnetic and ductile metal, which makes it ideal for creating thin, flexible sheets like aluminum foil for food wrap.
