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.

Explanation:

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.

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.

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.

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 .

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.

Answer:

Explanation:

1.Their genotype is either AA or AO

2.blood type B could have a genotype of either BB or BO

type AB or type O is more informative.

3. Someone with blood type AB must have both the A and B alleles. The genotype must be AB.

4.Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

C the humming bird will not live as long as the others

Explanation:

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.

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.

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.

Explanation:

Most electrical wire is covered in a rubber or plastic coating called insulation. ... The purpose of insulation covering the metal part of an electrical wire is to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors.

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.

What is the question?? :}

Explanation:

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.

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

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

This is a detailed simple solution as required

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.
