Answer:
all multicellular, make their own food - plantsall multicellular, eat other organisms - animalsmostly unicellular, some make there own food. others consume their food - protistsmostly multicellular, eat dead or decaying organisms - fungiExplanation:
All plants and animals are multicellular organisms. Plants are autotrophs, meaning they can make their own food (usually by photosynthesis). In contrast, animals rely on other organisms as a food source (are heterotrophs)
Fungi and protists are more variable. Protists are mostly small unicellular organisms, some perform photosynthesis to make their own food, others eat other organisms.
Fungi usually consume dead or decaying matter (decomposers)

4. a. viral genome is replicated using host cell's machinery
5. d. new viruses are assembled within host cell
6. e. the cell ruptures and releases new viruses to infect new cells
Explanation:
First, the virus attaches to the cell. Then it penetrates the cell membrane and inserts its genome inside the cell. The virus relies on the cell machinery to synthesize its proteins, and also to replicate its genome.
With these components being synthesized and replicated, new viral particles are assembled inside the host cell. Eventually, the cell ruptures, and the newly assembled viruses are released and able to attach to new cells to repeat the cycle
A student states that exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time. An experiment is carried out to test this hypothesis. One group of ten students sits quietly before squeezing a clothespin as many times as possible during a one-minute interval. A second group of ten students does 25 jumping jacks before squeezing a clothespin as many times as possible during a one-minute interval. What is the independent variable?
Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.

A characteristic common to eukaryotic cells that are not found in prokaryotic cells is the presence of mitochondria. Thus, the correct option for this question is D.
What is a Prokaryotic cell?A prokaryotic cell may be defined as a type of cell which is present in prokaryotes. This type of cell typically lacks a well-defined nucleus and other membrane-bound cell organelles. Organisms like bacteria, archaea, etc. possess this type of cell.
All prokaryotes and eukaryotes have a cell membrane known as a Plasma membrane. Most prokaryotic organisms have a small amount of genetic material in the form of a single molecule known as circular DNA.
Protein synthesis is one of the essential functions of all cell types. Ribosomes are significantly found in every type of eukaryotic as well as prokaryotic organisms like bacteria.
Therefore, the presence of mitochondria is a characteristic that is only common to eukaryotic cells but is not found in prokaryotic cells.

I took this test about it hope that helps :D
The role of the electron transport chain in the process of photosynthesis will be carrying electrons from photosystem 1, to photosystem to NADP. The correct option is C.
What is electron transport chain?An electron transport chain is a collection of protein complexes and certain other compounds that donate electrons from electron donors to electron acceptors via redox reactions and couple this electron transfer with the transfer of protons across a membrane.
Photosystems I and II are protein complexes found in the thylakoid membrane.
Their function is to capture high energy electrons from chlorophyll and pass them on to a series of electron carriers before splitting water to form oxygen and hydrogen ions and producing NADPH.
Electron transport contributes to the formation of a proton gradient, which drives ATP production and also stores energy in the reduced coenzyme NADPH.
This energy is used to power the Calvin Cycle, which produces sugar and other carbohydrates.
Thus, the correct option is C.

Atmospheric Layer Describe what happens to the temperature as altitude increases. Be sure to note specific altitudes where abrupt changes occur and how each layer is heated. Troposphere Stratosphere Mesosphere Thermosphere Exosphere Ionosphere
Answer:
Kindly Check explanation section.
Explanation:
The atmosphere has zones and each zones has it characteristics with respect to atmospheric conditions such as temperature, pressure and humidity.
So, the question only asked us to compare or show the temperature describe what happens to the temperature as altitude increases in each region of the atmosphere.
(1). Troposphere: the region known as troposphere in the atmosphere has a lower Temperature. The troposphere is a region in which the earth gets its radiation and re-radiates its electromagnetic radiation to give heat which later cools down.
(2). Stratosphere: what occurs in the region known as the stratosphere in the atmosphere is that there will be absorption of UV by the O3 layer which will in turn INCREASES THE TEMPERATURE.
(c). The Mesosphere: in this region of the atmosphere the temperature DECREASES.
(d). Thermosphere: there is surely an INCREASE IN TEMPERATURE in this region because of solar radiation.
(e). Exosphere: there is an INCREASE IN TEMPERATURE in this region too and the temperature increament is caused by ionization.
(f). Ionosphere: in this region, we have an INCREASE IN TEMPERATURE too be side of the solar radiation.

Many cells make and use an enzyme, called catalase, to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). What is the effect of catalase on the decomposition of hydrogen peroxide? A. It decreases the activation energy needed to start the reaction. B. It decreases the total energy released by the reaction. C. It increases the total energy absorbed by the reaction. D. It changes the ratio of the amounts of the two products.
Answer:
A. It decreases the activation energy needed to start the reaction
Explanation:
Organic catalyst which speed up the rate of organic chemical reaction is living cells are called enzymes.They have specific reaction site called active sites.This must be in prefect shape with the substrate for the organic chemical reaction to take place
When this occurs the minimum amount of energy of reaction to activate or stimulate the the atoms and molecules of the substrate to undergo chemical reaction is lowered.This energy of reaction is celled activation energy.
Catalase thought its active sites lowers the activation energy so that the molecules of H2O2 could break down to C02 and H2 faster,thereby reducing the time for theses product to form.The is the general roles of enzyme.To increase the rate of chemical reaction,by reducing the activation energy.
in what ways is ATP like a fully charged battery?
Answer:
ATP ATP can be compared to a fully charged battery because both contain stored energy, whereas ADP resembles a partially charged battery. Releasing Energy From ATP The energy stored in ATP is released when ATP is converted into ADP and a phosphate group.
Explanation:
The ATP molecule is comparable to a battery that can be recharged. It is ATP when ultimately charged. It's ADP when it's worn out. When the battery runs out, it is simply recharged rather than discarded.
What is ATP?A vital "energy molecule" in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers cells' energy by liberating its phosphate groups when it interacts with enzymes like ATP triphosphatase. The molecule comprises an adenine bicyclic system, a furanose ring, and a triphosphate chain.
The discovery of ATP was announced in 1929 by two research teams. It was isolated from mammalian muscle and liver by Cyrus H. Fiske and Yellapragada Subbarow at Harvard Medical School (Boston). Karl Lohmann discovered it in muscle tissues while working for the Kaiser Wilhelm Institutes in Berlin and Heidelberg.
Over the next 15 years, ATP separation from other sources came next. In 1987, Koscak Maruyama of Chiba University (Japan) provided a thorough analysis of ATP's discovery and structural elucidation.
Therefore, ATP is like a rechargeable battery because it can be recharged and discharged.

How do nutrients move through an environment? What drives the movement of nutrients?
Answer:
The nutrient cycle is a system where energy and matter are transferred between living organisms and nonliving parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.
The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment.
How do nutrients move?As the concentration of nutrients around the root system decreases, nutrients from higher concentration areas diffuse - or move - toward low concentration areas and the roots. They only move a short distance, however. Potassium (K) and phosphorus (P) primarily move via diffusion.The nutrient cycle is a system that transfers energy and matter between living organisms and non-living elements of the environment. This occurs when animals and plants consume soil nutrients, which are then released back into the environment through death and decomposition.The movement of nutrients to the root surface in response to a concentration gradient is referred to as diffusion. When nutrients are found in higher concentrations in one area than in another, there is a net movement to the low-concentration area, resulting in equilibrium.To learn more about : Diffusion.
