13. How do you identify the promoter gene?
1. distinguish between different types of mutations 2. explain why mutations may or may not affect phenotype 3. identify internal and external factors that regulate cell division 4.explain cancer in terms of the cell cycle
Answer:
1.)The types of mutations include: Missense mutation: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. Nonsense mutation: A nonsense mutation is also a change in one DNA base pair
.2.) Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
3.)External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells. Two of the most important internal factors are kinases and cyclins.
4.) In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides. ... In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.

What are found in both mitochondria and typical prokaryotic cells?
80S ribosomes and circular DNA
70S ribosomes and circular DNA
70S ribosomes only
circular DNA only
Answer:
B) 70S ribosomes and circular DNA
Explanation:
Remember: Mitochondria is found in the cytoplasm of almost all eukaryotic cells.
All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.
Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.

HOMER NOTICES HIS SHOWER IS COVERED IN GREEN SLIME. hI8S FRIEND BARNEY TELLS HIM COCONUT JUICE WILL GET RID OF THE SLIME. HOMER DECIDES TO SPRAY IT WITH HALF COCONUT JUICE. HE SPRAYS THE OTHER HALF WITH WATER AFTER 3 DAYS OF THE TREATMENT THERE IS NO CHANGE IN THE APPEARANCE OF THE GREEN SLIME OR EITHER SIDE OF THE SHOWER.WHAT IS THE INDEPENDENT VARIAB LE
DEPENDENT VARIABLE
CONTROL GROUP
CONSTANT
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.

Early scientists were confused by the Euglena because they wanted to classify all living things as either plants or animals. Why do you think the scientists were confused?
Answer:
Euglena perform photosynthesis through the presence of chloroplasts in their cells, but they are also able to feed like animals by consuming and digesting organic material. They have features of both an autotroph(an organisms that produces its own food, such as plants) and a heterotroph (an organism that can not produce its own food and instead need to consume organic matter). Due to having features associated with both plants and animals, this would cause confusion to the scientists at the time who struggled to classify them as either plant or animal.

Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined.
Answer:
The definition of the particular situation is outlined throughout the following section of the justification.
Explanation:
The query given seems to be incomplete. Please find the full issue attachment.
(a)
CO2 provides an inorganic component containing cellular mass. Throughout the atmosphere, plant species suck up CO2. Plants manufacture sugars throughout the mechanism of photosynthesis. Sugar is turned into glucose, cellulose as well as certain carbohydrates processed in cell walls. This raises the density of the plant. The process needs water, Carbon dioxide respectively.(b)
Sunlight is absorbed by chlorophyll as well as converted through chemical energy. The plant utilizes biochemical resources to synthesize sugars. The volume including its plant has risen due to the manufacture of sugars, respectively. For producing sugars, plants require light. The loss in mass has been caused by cellular respiration. There's this community of crops in the dark. They don't do photosynthesis, hence.Because to get power for something like the operations including its plant, individuals had to undergo respiration. So there is no photosynthesis, and therefore there is no sugar development. But instead to release energy, the sugar contained in the plant is eaten. And that's why the amount including its plants holding in darkness reduces.There are 3 steps given below for cellular respiration:
GlycolysisKreb's Cycle Electron Chain of TransportCellar respiration fills certain living things with energy.
⇒ [tex]C_6H_{12}O_6 + 6 O_2\rightarrow 6CO_2 + 6H_2O + (ATP) power.[/tex]
The generated CO2 has so far been delivered from the body including its plant. Therefore the plant mass was indeed decreased by this.

What is the approximate average yearly total snowfall gradient between locations A and B?
(1) 0.25 in/mi (2) 2.50 in/mi (3) 0.40 in/mi (4) 4.00 in/mi
Snowstorms that continue three hours or longer, have consistent wind speeds of at least 35 mph (about 56 km/h), and have visibility of less than a quarter mile are referred to be blizzards. Thus option C is correct.
What average yearly total snowfall gradient?The image demonstrates a snowfall gradient, or the variation in snowfall rates from one place to the next. Weather.com meteorologist Brian Donegan stated, “It may happen everywhere that gets snow showers and is fairly regular.”
For clouds and snow to form, there must be adequate moisture in the atmosphere. Snow cannot form if there is insufficient moisture. The atmosphere must continuously add moisture to the clouds in order for snow to continue to create and fall to the ground during heavier precipitation.
Therefore, 0.40 in/mi is the approximate average yearly total snowfall gradient between locations A and B.

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

carbohydrates is what gives everyone energy..
healthy carbs:= more fruit, starchy veggies like corn, peas, pasta,whole grain bread plus lean protein can help store more carbs in the fat layer of the body. when in active motion, muscles release bursts of energy, (fight or flight response)..
