Answer:
Rubisco is the major enzyme used to catalyse the carbon fixation step during the Calvin cycle in photosynthesis.
During carbon fixation, RUBP undergoes a redox reaction with CO2 to form 3-phosphoglycerate (a 3 carbon compound). 3-phosphoglycerate then undergoes phosphorylation by ATP and reduction by NADPH to form glycerate 3 phosphate molecules (main product), ADP and NADP+ molecules (by product).
Some Glycerate 3 phosphate produced are used to regenerate RUBP for the Calvin cycle to continue while the rest of the Glycerate 3 Phosphate is used to synthesise monosaccharides like glucose.
Without Rubisco, carbon fixation cannot occur and RUBP will not be able to combine with C02 to form a 6 carbon unstable intermediate the breaks down to form 3-phosphoglycerate and eventually undergoing more reactions to form glycerate 3 phosphate which is the basic product of photosynthesis used to synthesise glucose and eventually starch which serves as the world's food.
why is East Ferris running out of water
Answer:
East Ferris running out of water because the amount of available freshwater decreases when people use more than the amount that flows into their area.
East Ferris running out of water because the population of East Ferris is increasing over time, but the amount of rainfall in East Ferris stays about the same over time.
How is East Ferris running out of water?The population of East Ferris is increasing over time, but West Ferris is not running out of water because it rains more in West Ferris than in East Ferris.
In East Ferris, the population is increasing with time, but the amount of rainfall in East Ferris remains similar with time. The wind is moving in the direction from east to west and having upward movement of the humid air which gets cool and the condensation of water vapors takes place into clouds and falling of rain takes place.
Therefore, East Ferris is increasing over time, but the amount of rainfall in East Ferris stays the same.

Which of the following is a function of the kidneys?
O A. To balance water and salts from food so cells neither shrink nor
burst
O B. To balance carbon dioxide and oxygen so cellular respiration can
occur
O C. To filter out fiber and bacteria and send them to the large intestine
O D. To filter out salts and fats and send them to the urinary bladder
Answer:
D. To filter out salts and fats and send them to the urinary bladder
Explanation:
Kidney is an excretory organ in the systems of certain living organisms e.g humans. It is a bean-shaped organ responsible for getting rid of waste products in our body via urine and maintaining homeostasis in the body.
Among the many excretory functions of the kidney, they help filter out electrolytes e.g salts and fats out of the blood and pass them to the urinary bladder through tubes called ureter. The waste products are eventually passed out as urine from the bladder.

D.
Protozoans can be unicellular or multicellular.
Answer:

Explanation:
Answer:
B
Explanation:
Answer B is correct:
Because the biologists are continuing to learn more and more about
such minute organisms, protozoan systematics – that is, the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a topic of debate and change, still today.
Some of the rather LARGE and unwieldy taxonomic groupings of past years are particularly subject to revision with expansion of and refinement in the knowledge about the members of those – and related – assemblages. Paradoxically, the protozoa themselves are becoming more difficult to define with precision as our information about them and other microbial assemblages increases. Thus, presenting a single satisfactory circumscribed definition for them is not an easy task.

Answer A sounds so funny.
Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

The graph below shows drug levels in the blood and in a target organ through time, while taking Pill Type C in the Gizmo. The dosage schedule is one pill every two hours. What will eventually happen if the patient continues to take the pill on the same dosage schedule?
Answer:
I don't know man
Explanation:
Answer:
Correct Answer: B. The drug level in the target organ will level off and reach equilibrium.
Explanation:
As long as the dosage schedule is maintained, the drug level in the target organ and blood will stabilize. The reason for this is that as the concentration of drug increases in the organ and blood, the amount of drug removed by the kidneys increases as well, as each cubic centimeter of liquid removed from the blood by the kidneys contains a greater amount of drug. Eventually, the amount of drug removed in the time period between pills is equal to the amount that is added with each pill. As the graph below shows, the maximum organ drug level in this example is about 192 mcg/cc.
When Mendel crossed tall pea plants with short pea plants all of the offspring were tall. Which of the following explains the tall gene?
A) The tall gene is peas is recessive
C) The short gene is peas is dominant
B) The short gene in peas is recessive
D) The tall gene in peas is dominant
Answer: D: The tall gene in peas is dominant
Explanation:
When alleles are heterozygous, dominant genes will "overpower" the recessive gene.
The offspring in the pea plants had both alleles of the gene, but despite this, all of the pea plants were tall. This is because the dominant gene, the tall gene, was expressed over the recessive gene.
The correct answer is D.
B is also correct, but the question asks us to explain the tall gene, not the short one.

As a seedling , the strangler fig and host tree have a relationship that is described as commensalism . Why is commensalism a good description for this relationship ?
Answer:
It merely uses the host tree to get closer to the sunlight and rain, and finds nutrients in decaying leaves and soil caught in nooks of the host tree's branches . This is a case of commensalism: one organism benefits while the other is unaffected.
Explanation:
The relationship between the strangler fig and a host tree would be described as commensalism because the strangler benefits from the relationship while the host tree is unaffected.
Commensalism refers to a relationship between two organisms in which one of them (the commensal) benefits and the other (the host) is unaffected in any way.
As a seedling, the strangler fig grows harmlessly around the a host tree. As the seedling develops to a more mature plant, it starts extending its branches and roots around the host plant, eventually strangulating the host plant.

What moderates weather so that highs and lows are less extreme?
Answer: Is the condition of Earth's atmosphere
Explanation:
The climate of Earth's atmosphere balances the seasons so that high and lows are less extreme.
What is Weather?Weather is defined as the state of the atmosphere, like as the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather events occur in the troposphere which is the lowest layer of the planet's atmosphere present below the stratosphere.
Weathers refers to day-to-day temperature, precipitation, and other atmospheric conditions, while climate is the term for the average of atmospheric conditions over long periods of time.

An energy pyramid shows how energy flows through an ecosystem. An image is provided. Each level gets only about 10% of the energy from the previous level. If living systems follow the law of conservation of energy, where does the remaining 90% of the energy go?
A. A It is used by decomposers during decomposition.
B. B It is converted into heat and energy for life functions.
C. C It is converted to matter during digestion.
D. D It is used by organisms in the lower trophic level.
Answer:
b
Explanation:
some is used, some is wasted by giving off heat, being excreted, etc
The statement (B) is correct. It is converted into heat and energy for life functions.
What is an ecosystem?An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Moreover, an energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level. The energy in an energy pyramid is measured in units of kilocalories (kcal).
Therefore, a pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
