The graph shows the growth and reproduction in 4 different cells, A, B, C, and D, over time. Use the graph to answer questions below.
Answer: A.
Explanation:
Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.
Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.
Firefly luciferase is the light-emitting enzyme responsible for the bioluminescence of fireflies and some types of beetles. This process occurs in specialized light-emitting organs, usually on a firefly's lower abdomen. The enzyme catalyses the firefly chemical luciferin, by binding to it and spending up the chemical reaction that combines oxygen molecules to produce oxyluciferin. Besides, oxygen this requires ATP. Because of the requirement of ATP, firefly luciferases have been used extensively in biotechnology. How do the enzymes speed up the chemical reactions and produce bioluminescent light?
Answer:
Luciferase transforms luciferin into oxyluciferin while consuming ATP and O₂, and causes the emission of light.
luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light
Explanation:
Fireflies are organisms that emit cold light by the process of bioluminescence. It is a chemical reaction of male individuals to attract the females that also respond by emitting light.
Luciferin is the molecule responsible for light emission. The chemical reaction involves the luciferin molecule, ATP molecule, enzyme luciferase, and oxygen molecule. Luciferin, the responsible molecule for light emission, is transformed into oxyluciferin by the enzyme luciferase. The enzyme consumes oxygen and ATP, which is the principal source of energy in living beings. Finally, a light of about 560 nm is released.
luciferin + ATP + luciferase + O₂ → oxyluciferin + AMP + CO₂+ luciferase + light
Almost the entire amount of energy involved in the reaction turns into luminous energy. ATP used for this light production process comes from the photosite´s mitochondrial electronic chain, responsible for the organism´s energy production.
Photosites are the cells responsible for light production, and many of their mitochondria are placed near the plasmatic membrane to catch oxygen.
Oxygen gets in the organisms through the lantern trachea. During the respiration process, photosites consume oxygen. Mitochondria placed in the cell periphery near the cell membrane catch the oxygen molecules and produce ATP. ATP produced by oxidative phosphorylation is involved in the production of oxyluciferin, turning into AMP.
Posteriorly, the oxyluciferin molecule is recycled back to luciferin. This process shows how chemical energy turns into luminous energy.

Question 4 of 16 Which chemical equation models a synthesis reaction ? O A. 2Na+MgCl 2 2NaCl+Mg O B. H 2 O+CO 2 H 2 CO 3 C. HCl+LiOH LiCl+H 2 O O CO 2 C+O 2
Answer:
The chemical equation which is a model of synthesis reaction is option B
B. H₂O + CO₂ ---> H₂CO₃
Explanation:
A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.
A synthesis reaction is illustrated below:
A + B ----> C
In the illustration above, A and B are two chemical substances which serve as the reactants in the chemical reaction. A and B combine with each other to form a product C.
Common synthesis reaction include:
1. The reaction of sodium with chlorine to produce sodium chloride: Na + Cl ---> NaCl
2. The synthesis of Nitrogen (iv) oxide from nitrogen (ii) oxide and oxygen: 2NO + O₂ ---> 2NO₂
3. The synthesis of sulfur trioxide from sulfur dioxide and oxygen: 2SO₂ + O₂ ----> 2SO₃
From the given chemical reactions, the model of a synthesis reaction is option B
H₂O + CO₂ ---> H₂CO₃
An individual observation can become a scientific theory.
False
True
Answer:
the answer is false: A scientific theory is a hypothesis that has been extensively tested, evaluated by the scientific community, and is strongly supported. Theories often describe a large set of observations, and provide a cohesive explanation for those observations. An individual cannot come up with a theory.

A roan cow is crossed with a red cow. What percent of the offspring will be roan?
Answer:
Red cows have a dominant red allele and white cows have a dominant white allele. When a red cow mates with a white bull, they can have offspring that have the color that is called Roan which is a red and white spotted appearance. This is an example of co-dominance
Explanation:
CORRECT ME IF I AM WRONG
If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.
CO-DOMINANCE:A roan cow phenotype is a product of co-dominance between red (R) and white (W) alleles. This means that a roan cow will have a RW genotype. If a roan cow is crossed with a red cow i.e. RW × RR, the gametes produced by each cow is as follows:RW - R and WRR - R and RUsing a punnet square, the following offsprings of cow will be produced: 2RR, and 2RW. This means that the percentage of roan cows in the offspring will be 50% i.e. ½ × 100 = 50%.Therefore, If a roan cow is crossed with a red cow, the percentage of roan cow in the offspring will be 50%.

Define groundwater and explain how it relates to the terms water table, aquifer, and confined aquifer.
Explanation:
Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater. An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. Groundwater separated from atmospheric pressure by relatively impermeable material is termed confined groundwater. When such zones are penetrated by wells, the water rises above the point at which it was first found because a confined aquifer is under pressure exceeding that of atmospheric pressure.

In order to keep up with the food demands of an increasing human population, farmers use fertilizers and other agricultural
technologies to grow and harvest more food. How do fertilizers negatively impact
the environment?
OA. The rate of nutrient depletion increases in soil that has been fertilized.
OB. Run-off from fertilized land increases nitrogen levels in ecosystems and encourages algal growth.
OC. Fertilizers are difficult to apply and require heavy machinery which damage land.
OD. Fertilizers allow crops to grow bigger and faster, so they can feed more people.
Answer:
OB. Run-off from fertilized land increases nitrogen levels in ecosystems and encourages algal growth. is the correct answer.
Explanation:
because This in turn is leading to global warming and weather changes.
A. The rate of nutrient depletion increases in soil that has been fertilized.
It increases nitrogen for better yield, but it affects the nitrogen cycle.

Endo and exocytosis:
A. Passive transport with the concentration gradient, requiring no energy.
B. Active transport of large molecules with the concentration gradient, thus requiring no energy.
C. Active transport of large molecules in and out of the cell. Requires energy.
Answer:
C. Active transport of large molecules in and out of the cell. Requires energy.
Explanation:
endo- the formal definition is “endometrial glands and stroma existing outside the endometrial cavity”. Essentially, it is tissue that resembles the endometrium (lining of the uterus), that exists other places. Most often, it is found in the pelvic peritoneum, or the lining of our abdominal cavity.
Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
Answer:
C. Active transport of large molecules in and out of the cell. Requires energy.
Explanation:
Endocytosis and exocytosis is an active transport of large molecules in and out of the cell, which requires energy.
