what is occurring during the mitosis phase
Answers
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

Answer:
all are correct. hope this helps
Explanation:
Answer:
D. All are correct.
Explanation:
Selective breeding allows producers to select and breed parent organisms with desired traits to produce offspring with more desirable characteristics. This process creates offspring who are genetically superior to the parent organisms, thus improving plants and animals with each generation.

You isolate an organism from a water sample and test it with a catalase test and grow it in thioglycollate medium. The results showed bubbling after the addition of hydrogen peroxide and a band of growth at the top of the thioglycollate tube. What is the most likely oxygen classification of your organism
Answers
Answer: The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM.
Explanation: Most medically important bacteria can be grown artificially in the laboratory provided the atmospheric conditions and temperature are correct and the culture medium used contains the required nutrients.
The thioglycollate medium is used to differentiate oxygen requirements in an isolated organisms. While catalase test is used to differentiate catalase producing from non-catalase producing organisms.
Differences in the effect of oxygen on bacterial growth provide a further way of classifying bacteria:
● OBLIGATE AEROBES, which require free oxygen to grow,
● obligate anaerobes, which are unable to grow in free oxygen,
● facultative anaerobes, which can grow in conditions in which oxygen is present or absent,
● microaerophiles which grow best in conditions of reduced oxygen concentration.
The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM because from the result of the test carried out on the isolated organisms,
--> The organism is catalase positive as it was able to breakdown hydrogen peroxide to oxygen and water( bubbling after the addition of hydrogen peroxide confirmed it as positive). Catalase is an enzyme produced by all aerobic organisms.
--> while in the thioglycollate medium the organism grew at the top of the test tube in order to absorb maximal amount of oxygen.

What is the function of ATP in living things? 1
Answers
Explanation:
The function of ATP IN living organisms is that ATP is stored in all the cells for energy of all cells.
ATP captures the chemical energy by digesting food particles, breaking it down to deliver into the
cell process enough to disperse ATP throughout the bloodstream for energy to every cell of the body, to work properly in digestion, releases it to fuel all cells in the body, this is the last process for fuel in the cell system in the digestive process..

Answer:
T-protease would be active in the stomach and W-protease would be active in the intestines.
Explanation:
Acidic pH's are considered to be less than 7 and 7 is considered neutral. Due to this we know that T-protease is more active in more acidic pH's meaning it would be most active in the acidic stomach.

Sickle cell anemia is a genetic condition that occurs because of a single point mutation in the DNA gene for hemoglobin. How is this mutation expressed in humans?
A.) The protein coded by the DNA has a different amino acid sequence
B.) The chromosome caring this gene changes shape during cell reproduction
C.) The hormones in the bladder change by increase differences in genes
D.) The carbohydrate code by the DNA has a different structure
Answers
Answer:
B.) The chromosome carrying this gene changes shape during cell reproduction
Explanation:
According to this question, Sickle cell anemia is a genetic condition that occurs when the HBB gene that codes for haemoglobin protein undergoes a point mutation. Mutation alters the genetic sequence of a gene.
This mutation expresses itself when the chromosome 11 carrying the mutated gene changes shape during cell reproduction. Normal Red Blood Cell has a disc-shaped structure, however, this mutation causes a change in shape of the chromosome involved.
g Humans have two sources of cholesterol: absorption from ingested food and de novo synthesis by the liver. High levels of cholesterol in the blood correlates with cardiovascular disease, but cholesterol is required to regulate membrane fluidity and is a precursor for important molecules like steroids and bile acids. Thus, humans evolved several types of regulation of cholesterol levels. How does the human body compensate for excess consumption of cholesterol in the diet
Answers
Answer:
Explanation:
Cholesterol is an important dietry intake that is gotten from saturated fats
About 200–300 mg of this dietry intake is produced or added daily.
The body compensates for excess cholesterol intake by reducing the amount of cholesterol that is synthesized. This is done by reusing the existing cholesterol in the body and the excretion of excess cholesterol into the digestive tract this is done by the liver through the bile.
About 50% of the excreted cholesterol is reabsorbed back into the bloodstream for use by the small intestines.

Which of the labeled structures is an adaptation that is primarily responsible for helping a paramecium control its water balance?
Paramecium diagram
A. Structure A
B. Structure B
C. Structure C
D. Structure D
Answers
Structure D , The term "contractile vacuole" refers to this structure. The vacuole gathers extra water from the cytoplasm and contracts to release it. As a result, paramecium doesn't swell and explode in hypotonic liquids.
Why are contractile vacuoles necessary for organisms?Specialized contractile vacuoles control the amount of water in cells. Its spherical form allows it to gather extra cell fluid and empty it outside. It is essential for preserving the osmotic pressure inside the cell. Protists are eukaryotes with only one cell and are found in wet and aqueous habitats.
The name "contractile vacuole" refers to what?As its name implies, the contractile vacuole expels water from the cell by contracting. The contractile vacuole periodically expands (collecting water) and contracts (releasing water). Several seconds are required for one cycle, depending on the species .

One hummingbird is born with a short, stout beak as a result of a genetic mutation, the humming bird will not live as long as the others.
What is mutation ?Mutations are defined as the change in the nucleotide sequence of genetic material due to different process such as substitution, deletion or insertion of the nucleotides leading to changed or faulty protein.
The type of mutations leads to the early and delayed termination of the transcription of a gene, mutation of a single nucleotide leads to termination of transcription otherwise called as nonsense mutation.
If a mutation shows no effect on the protein, known as the silent mutation.
It won't be able to gain sufficient resources/ necter like the others hence it will most likely have poor body condition and will not live as long.

1.Compare and contrast a cold and warm front.
2. Along which type of front is the weather the calmest? Justify your answer.
Answers
Answer:
A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.
ExplanationThere are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts. the direction of flow of the air mass and its characteristics. so based on what we know i would say that warm fronts are calmest
Environmental scientists calculating pollutant half-lives often define a transport rate constant that is analogous to a reaction rate constant and describes how a pollutant moves out of an ecosystem. In a study of the gasoline additive MTBE in Donner Lake, California, scientists from the University of California, Davis, found that in the summer the half-life of MTBE in the lake was 26.01 days. Assume that the transport process is first order. What was the transport rate constant of MTBE out of Donner Lake during the study
Answers
Answer:
k ≈ [tex]2.7 *10^{-2} d^{-1}[/tex]
Explanation:
For a first order reaction
Half life ( [tex]t_{1/2}[/tex] ) = 0.693 / k
k = rate constant
[tex]t_{1/2}[/tex] = 26.01
hence k = 0.693 / ( 26.01)
k ≈ 2.7 * 10^-2 d^-1
