These ecological levels of organization are ranked in ascending order as follows: D. individual → population→ community→ ecosystem.

An ecosystem can be defined as a biological community that is typically made up of living organisms (biotic factors) such as individuals and the physical environment (abiotic factors) in which they interact.

Basically, the individual organisms in an ecosystem forms a population and this also gives rise to a community. This ultimately implies that, the ecological levels of organization are ranked in ascending order as follows:

Answer:

35% thyamine, 15% guanine and 15% cytosine

Answer:

35% thymine, 15% guanine and 15% cytosine

Explanation:

35% thymine, 15% guanine, and, 15% cytosine because the exact same amount of thymine would pair up with adenine, thus thymine has to be 35%. Thymine and adenine take up 70% of the DNA the rest has to equal 30%. Guanine and cytosine make up the rest, which is 30%, thus we have to split it evenly because they pair up with each other. Therefore, guanine and cytosine equal 15%.

Answer:

All living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.

In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

Answer:

Guanine

Explanation:

C to G and A to T

In RNA, cytosine (C) forms a base pair with guanine (G).

This pairing is based on complementary base pairing rules, where cytosine always binds with guanine through three hydrogen bonds.

In RNA, as well as in DNA, the base pairs play a crucial role in the structure and function of genetic material.

The pairing between cytosine and guanine, along with adenine (A) pairing with uracil (U) in RNA (or thymine (T) in DNA), creates the double-stranded structure of nucleic acids.

These base pairs provide stability and ensure accurate replication and transcription of genetic information, contributing to the essential functions of RNA and DNA in various biological processes.

Pond becomes a meadow as a result from the process of natural eutrophication.

Layers of detritus accumulate when pond plants develop, die, and disintegrate and there is an increase in the level of nutrients. Over time, these layers of decaying debris rise the pond floor. The pond floor eventually gets near enough to the bottom that emergents can grow all the way across it. The ponds develop marsh meadows as a result of this.

Hence, the correct option is A. Pond becomes a meadow.

Answer:

The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. ... This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

Answer:preventing or reducing pollution from the land and from streams

Explanation: This is true because these said streams and other bodies of water can flow into the ocean

The key to protecting the oceans is preventing or reducing pollution from the land and from streams is reducing population growth along the coastline. The correct option is A.

Pollution is the release of potentially harmful substances into the environment. These potentially damaging compounds are referred to as pollutants.

Despite the fact that metropolitan areas are often more polluted than the countryside, pollution can nonetheless migrate to isolated locations where no one lives.

For instance, it has been demonstrated that the Antarctic ice sheet contains chemicals and pesticides. The Northern Pacific Ocean's Great Pacific Garbage Patch is a vast collection of little plastic waste.

Therefore, the correct option is A, reducing population growth along the coastline.

The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.

What is fusion?

Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.

Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.

Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.

Thus, the correct option is 4.

Answer:

The images show fossils of a modern bird and two extinct organisms (a Tyrannosaurus rex and an Archaeopteryx). Based on the structure of the three organisms, it can be concluded that They share a common ancestor.  The Archaeopteryx and bird have wings, while dinosaurs have limbs. So, it can be concluded that The Archaeoptery came after dinosaurs but before birds.

Explanation:

Just got a 100% on the test. Have a good day!

Looking at the images, we can conclude that they share a common ancestor and the Archaeologyx came after dinosaurs but after birds.

The term evolution refers to changes that occur as one organism gradually disappears an another appears in its place. According to Charles Darwin, natural selection is the reason behind evolution.

Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.

Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)

Answer:

Battery Acid

Explanation:

Since Battery Acid is closest to 0 on the pH scale, it is very acidic, and of the other choices, the most acidic.

Battery acid is the most acidic from all of the following substances.

pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. A strong acid is one that completely ionizes (dissociates) in a solution.

pH is a measure of how acidic/basic solution is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. now battery acid is 1 which indicates it is strong acid among all of them.

Disadvantage: You don't know the exact ph value on a regular scale.

Explanation:

The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.

On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.
