Answer:
They can perform photosynthesis.
Explanation:
Autotrophs are organisms that can produce their own food, and heterotrophs are organisms that feed on other organisms. This means that the ameba and paramecium can eat only other microorganisms.
The euglena is not limited to this. Hypothetically speaking, if there were no other microorganisms around it (which is unlikely), the euglena would not die as long as it is exposed to sunlight. Thanks to chloroplasts, organelles that contain chlorophyll, it can perform photosynthesis - a process in which, with the help of sunlight, carbon dioxide, minerals, and water are used to synthesize food.

Positive feedback mechanisms are useful for which of the following situations?
A. Modulating a stimulus to stay within a defined range ·
B. Modulating a stimulus to move toward an endpoint
C. Amplifying a stimulus to move toward an endpoint
D. Amplifying a stimulus to stay within a defined range
Answer:
C. Amplifying a stimulus to move toward an endpoint
Explanation:
The mechanism of inputs and outputs are operated by biological systems. It is either it is caused by an event or it is causing a certain event. Feedback is very important in this system. Feedback loops are the paths in which a change to the system brings about an alarm that actually brings a certain result. In a positive feedback loop, the product of a reaction brings an increase in the reaction. This is carried out by amplifying effects of a product (stimulus) to move toward an endpoint.

Answer:
D.
Explanation:
DO I need an explanation? No, of course not.
People should take shelter in an interior room without windows in a location in Florida most likely take if the local weather forecast predicts a tornado.
What do you mean by tornado?A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud.
Tornadoes form when warm, humid air collides with cold, dry air. The denser cold air is pushed over the warm air, usually producing thunderstorms.

[50 points... Will give brainliest] Explain how natural selection is impacted by genetic differences, variation, and survival.
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Minerals are rarely used in everyday life true or false
Answer: False
Reason: We Use Minerals In our day to day life, when it comes to cooking, or burning. We use Salt to cook amazing meals, and some pots and pans have minerals built in to them so that they last longer over the years you cook with them. When we burn in the fireplace or in the backyard, some of us use coal and light it up, and sometimes, we use minerals to make buildings. In one of my neighboring towns, their City Hall has little mineral pieces built into the City Hall. I hope this helps, and happy holidays! :)

Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.
What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?
A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.
B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.
C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.
D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
Answer:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.
Explanation:
hope this helps you a little have a great day sir/mam
Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy. Thus option A is correct.
What is the function of catalase ?Catalase is a common enzyme present in all living organisms.
These are tetramer molecule consisting of four polypeptide chains, each of these chains are over 500 amino acids.
In mammal it is found in liver and contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide.
In mammalian cell, Catalase involve in decomposition of most toxic substance called hydrogen peroxide into less toxic products like water and oxygen.
It protect the cell from oxidative damage by reactive oxygen species.
The optimum pH and optimum temperature for the activity of this enzyme ranges from four and eleven depending on the species.
Thus option A is correct.

In the movie Darwin struggled with publishing his ideas on Evolution by Natural selection. He was afraid of the cultural implications of his discoveries. Do you think his idea of Evolution by Natural Selection was a "dangerous idea"? Back up your claim with evidence from the video and 1 other source. Explain your reasoning.
Answer:
Yes.
Explanation:
Yes, I think Darwin idea of Evolution by Natural Selection was a "dangerous idea" because the people at that time was unable to understand his idea. The people at that time had their own believes which they were followed and rejected everything which were against their believes so this idea of evolution was against the idea of people at that time due to which Darwin was afraid of the cultural implications of his discoveries.

The endosymbiotic theory states that the mitochondria of eukaryotes are the evolutionary result of a Proto-eukaryotic cell engulfing an aerobic bacterium, which then evolved into the mitochondrion. Which characteristic of mitochondria supports this theory of development? A retention of a single layer membrane B retention of the chlorophyll pigments C retention of their own genome D retention of their own nucleus
Answer:
The correct answer is - C. retention of their own genome.
Explanation:
The endosymbiotic theory is a theory that suggests that eukaryotic cells are developed from prokaryotic cells. According to this theory, organelles like mitochondria are developed in eukaryotic cells as the result of proteo-bacteria cells engulfing aerobic bacteria.
The evidence of this theory can be seen as the mitochondria has their own genome such as circular DNA and ribosomes as the prokaryotes.
