Which statement explains how producers are dependent upon consumers for their survival?
O A. Consumers supply oxygen for producers to undergo aerobic respiration.
O B. Consumers produce carbon dioxide for producers to use during photosynthesis.
O C. Consumers provide chemical energy needed by producers for cellular respiration.
o D. Consumers make lactic acid that producers use in photosynthesis.
Answer:it’s B
Explanation:
The option that explains how producers are dependent upon consumers for their survival is as follows:
Consumers produce carbon dioxide for producers to use during photosynthesis.Thus, the correct option is B.
How do producers produce their energy?Producers produce their energy through the process of photosynthesis which involves the active role of carbon dioxide and water in presence of sunlight through which the inorganic carbon of carbon dioxide is converted into the organic carbon of carbohydrate (glucose).
This carbon dioxide for plants is delivered by the consumers through exhaled respiration.
Therefore, the correct option for this question is B.

If 2 atoms of gold have the same properties, does an electron have the same properties of gold
Place mercury in the reactor. After a large amount of work, only a tiny portion of gold is created.
Decontaminate the resulting gold. This is harder than it sounds because you can't separate out non-radioactive gold from radioactive gold using purely chemical methods.
It should be obvious from this process that it currently costs much more money to create non-radioactive gold than you could ever earn by selling the gold. Creating gold from other elements is currently an expensive laboratory experiment and not a viable commercial activity. Perhaps technology will improve enough in the future to make creation of gold in nuclear reactors a profitable economic enterprise.

In the night sky, stars often look like a multitude of bright lights barely distinguishable from one another. But the fact is that stars vary greatly. The differences are difficult to see from far away. Can you guess the ways in which stars differ from one another? And what do they have in common?
Answer:
The correct answer is -
differences: color, brightness, temperature, size, and mass
similarities: They are balls of gas, mostly hydrogen and helium
Explanation:
Stars look mostly the same from anywhere or any place and tough to differentiate or distinguish one from another. Star can be different on the various ground even they look similar from far away.
Stars can be of various colors from red to blue and brightness can be different as well, color depends on temperature, and brightness depends on the size of the star.
Stars are grouped by the size that ranges from dwarf to supergiant. The temperature of the stars also varies which affects the color and brightness as well.
Stars are the big balls of gases composed of mainly helium and hydrogen all are always under a nuclear reaction.
Answer:
Stars have different masses and sizes. They are composed of different mixtures of elements. All stars, however, are powered by nuclear fusion and have a limited life-span.

How does Rutherford’s model of the atom compare with Thomson’s model? They both describe atoms as small, indivisible spheres. They both describe electrons as moving around the nucleus. They both describe electrons as being surrounded by the positive matter. They both describe atoms as being made up of positive and negative matter.
Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
Both Rutherford and Thomson's model both describe atoms as being made up of positive and negative matter. The correct option is D.
What is an atom?An atom is a matter particle that truly represents a chemical element. An atom is made up of a central nucleus encased by one or more electrons. Each electron carries a negative charge.
Thomson's plum pudding the atom model contained negatively charged electrons within a positively charged "soup."
The gold foil experiment by Rutherford demonstrated that the atom is mostly empty space with a tiny, dense, positively charged nucleus. Rutherford proposed the nuclear model of the atom based on these findings.
Thus, the correct option is D.

Christina is so excited about her wedding that she tells her coworker Meredith it is exactly 43,200 minutes away. Help Meredith figure out how many days away the wedding is so that she can add it to her calendar.
Answer:
The correct answer would be - 30 days.
Explanation:
Given:
Time to go for the marriage - 43,200 minutes
Solution:
we know:
1 hour - 60 minutes
1 day - 24 hours - 60 * 24 = 1440 minutes
so the days in the 43200 minutes would be -
43200/1440 = 30 days.
Thus, the correct answer would be - 30 days.

A scientist is examining slides of cells from organisms in different groups. What two
features would the scientist use to distinguish a plant cell from an animal cell?
A•presence or absence of mitochondria
B•presence or absence of a cell wall and chloroplasts
C•presence or absence of a nucleus and cell membrane
D•presence or absence of a cell membrane and cytoplasm
The two features would the scientist use to distinguish a plant cell from an animal cell are the presence or absence of a cell wall and chloroplasts. Thus option B is correct.
what is function of chloroplast ?Chloroplasts are the membrane bound organelle present only in photosynthetic organism like plants and algae; They are located in mesophyll cells of leaves and have a high concentration of chlorophyll pigment which absorb sunlight and absent in animal cell.
Chloroplast has extra-nuclear DNA, these are semiautonomous in nature; They synthesize food that is glucose by the process of photosynthesis by absorbing sunlight into chemical energy.
It is major house which involve in the production of NADPH and molecular oxygen (O2) released by the photolysis of water; It also produces ATP from photosynthesis.
It also indirectly participate in generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.
Thus option B is correct.

Which biomolecule determines a person's ability to clot blood properly?
A- Glycogen
B- Lipids
C-Carbohydrates
D- Nucleic Acids
Answer:
D- Nucleic Acids
Explanation:
Blood clotting is a process whereby a person's blood coagulates due to the formation of a white fibrous protein substance called FIBRIN. The essence of blood clotting is to prevent excessive flow/waste of blood when a blood vessel is wounded.
However, certain substances are needed for this process of blood clotting to occur in our body. Some individuals lack this substances and hence bleed continuously during injury, a condition known as HEMORRHAGE. The substances such as FIBRIN, a protein needed for blood clotting is encoded by GENES which makes up DNA (a type of nucleic acid).
Therefore, NUCLEIC ACID biomolecules determines a person's ability to clot blood properly because nucleic acids make up DNA, which contains segments (genes) that encode the synthesis of proteins (fibrin) needed for blood clotting to occur. Hence, it all boils down to NUCLEIC ACIDS.

What could happen if an organism could not maintain homeostasis
When an organism fails to maintain homeostasis, the organism typically becomes ill, and it will die.
what is homeostasis ?homeostasis a self-regulating process in which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival.
If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues, stability attained is actually a dynamic equilibrium, in which continuous change occurs.
Any system in dynamic equilibrium tends to reach a steady state, a balance that resists outside forces of change.
