Accoring to the data table, Molly observed rust on the sample of iron filing and dries the sample thoroughly. She then finds the mass of the entire sample and finds it has more mass than the 188g of the original sample. As the rusted iron filing occurred in an open system, which of the following best explains the increase in mass?

Select one:
A. The sample gained mass because rust is a different color than the iron fillings, and the different color rust has more mass that the original iron fillings.
B. The sample gained mass because the iron fillings combined with oxygen in a chemical reaction, thus making the final rusted sample to have more mass.
C. Molly made a procedure mistake when measuring the mass of the entire sample. She should remeausre her sample.
D. The sample gained mass because rust is a physical change and the color change causes the mass to be more than the original sample.

Answers

Answer:

Multicellular

Explanation: used quizziz

Of the options listed, "They are prokaryotic" and "They are not multicellular" are characteristics that both blue-green algae and bacteria share.

What are blue green algae?

Blue-green algae, also known as cyanobacteria, are a type of bacteria that are capable of performing photosynthesis. This makes them unique among bacteria, as most other bacteria do not have the ability to produce their own food in this way. As a result, blue-green algae play an important role in the carbon cycle and contribute to the production of oxygen in the Earth's atmosphere.

Blue-green algae can be found in a variety of environments, including fresh and salt water, soil, and rocks. Some species are free-floating, while others form colonies or filaments. In certain conditions, such as nutrient-rich water or high temperatures, blue-green algae can grow rapidly and form blooms, which can have negative impacts on aquatic ecosystems and human health.

Despite their classification as bacteria, blue-green algae have a number of characteristics that are more similar to algae than to other bacteria, which is why they are sometimes referred to as "blue-green algae."

How are photosynthesis and cellular respiration related?

A. The products of photosynthesis are the reactants of cellular
respiration

B. Cellular respiration is the process animals use to produce glucose,
while photosynthesis is the process plants use to produce
glucose.

C. Photosynthesis produces water molecules, while cellular
respiration splits water molecules apart.

D. Cellular respiration provides the energy for photosynthesis.

Answers

Answer:

I would say your answer for this question would be Option D: Cellular respiration provides the energy for photosynthesis.

Explanation:

Photosynthesis is  the process by which plants use the energy from sunlight, carbon dioxide, and water and convert them into food, and Cellular resipration is the process by which organisms use oxygen to break down glucose and convert it to usable energy. That means that Option B can be crossed out, along with Option C. In Option A, the products of photosynthesis are not the reactants of cellular respiration, but rather the user of the energy that Cellular respiration provides. That means you can cross out Option A, and now you are left with Option D as your answer.

Answer:

A. The products of photosynthesis are the reactans of cellular respiration

what is a ecosystem? write 2 to 5 sentences to explain it​

Answers


Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.

For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.


An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.

What is one function of the organ system shown below in the picture?

Answers

The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced.

The circulatory and respiratory systems are involved in respiration. They provide oxygen to the body cells and remove carbon dioxyde. The correct option is A. To remove carbon dioxyde from the body.

Two systems work together when providing oxygen to the body cells and removing carbon dioxide: The circulatory and respiratory systems

• Respiratory system

This system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.

• Circulatory system

This system is in charge of driving oxygen to the organism's tissues and cells and taking away carbon dioxide from them.

These gases are in the oxygenated and deoxygenated blood, respectively.

The heart bombs blood through arteries, veins, and capillaries to the whole body.

The blood carries oxygen to different tissues.

This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.

Types of circulation

• Lung circulation

1. Moves blood between the heart and the lungs.

2. Deoxygenated blood goes from the heart to the lungs

3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.

4. Carbon dioxide is released by exhalation.

5. Blood absorbs oxygen from small air sacs named alveoli.

6. Oxygenated blood returns to the heart.

Systemic circulation

1. Carries blood between the heart and the rest of the body.

2. Oxygenated blood leaves the heart and moves to all the cells in the body.

3. Deoxygenated blood returns from tissues to the heart.

According to thi framework, the function of the organ system shown in the picture is to remove carbon dioxyde from the body. Option A.

Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways

Explanation:

An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.

How is structure of DNA adapted to its function

Answers

Answer:

Deoxyribonucleic acid is the macromolecule carries the genetic information. It has two phosphate sugar back bone chains which are joined together with the help of nucleotides (A, T, G, and C). This set of nucleotide refers as gene. These genes define the primary function of DNA to carry genetic information. This DNA structure gets coiled in manner that can carry large amount of information. These nucleotide sequences have ability to get transcribed into protein molecule with the help of translation and transcription factors.

One strand of sequence is sufficient to maintain coding sequence. The pair wise structure helps in case of one strand of structure get damaged and it required in process of replication.

Base stacking provides the stability in the structure of the DNA. The corresponding nucleotides combine with other molecule and minimize the hydrophobic effect. This molecule combines in the perpendicular alignment to the DNA base line.

It often found that TATA box on 5’ end. It is found that on 5’ because process starts from 5’ end and TATA box have A, T nucleotide. These molecules have double hydrogen bond, which is weaker then G, C pair.

Explanation:

The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.

DNA sequencesDNA has nucleotide made up of pentose sugar and phosphate backbone, and nitrogenous bases in a particular sequence.The sequence converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodiesDNA winds into a double helix, with hydrogen bonding between the bases of each strand like the rungs of a ladder.The order of nucleotides in a gene dictate the amino acid sequence of the proteinDNA acts to store information while proteins are the effector molecules.

Thus, The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.
