The genotypes of gamete produced by each of these plants can be determined by splitting their genotypes in half, specifically, one of each homologous pair of chromosomes is pulled into each gamete.

By so doing, the gametes of the pure-breeding tall, peach fuzz, round plant and the gametes of the pure-breeding dwarf, the smooth, oblong plant can be determined. Therefore, the gamete genotypes produced by the pure-breeding tall, peach fuzz, the round plant can be TTffRr since it is homozygous for the alleles, round (R), peach fuzz (f), and tall (T) while heterozygous for the allele hairless (r).

On the other hand, the gamete genotypes produced by the pure-breeding dwarf, smooth, oblong plant can be ttFfrr as it is homozygous recessive for the alleles, tall (T), peach fuzz (f), and round (R), while heterozygous for the alleles, oblong (F) and hairless (r). Therefore, the gamete genotypes produced by the pure-breeding tall, peach fuzz, round plant and the gamete genotypes produced by the pure-breeding dwarf, smooth, oblong plant can be TTffRr and ttFfrr, respectively.

The σ sub-unit of the RNA polymerase is involved in the initiation stage of bacterial transcription.

During this stage, the RNA polymerase binds to the DNA promoter region with the help of the σ sub-unit, which recognizes specific sequences in the promoter region and guides the RNA polymerase to the transcription start site. Once the RNA polymerase is properly positioned, the σ sub-unit dissociates and the elongation stage of transcription begins, during which the RNA polymerase synthesizes a complementary RNA molecule using the DNA template strand.

The termination stage of transcription occurs when the RNA polymerase reaches a termination signal and releases the newly synthesized RNA molecule. Splicing is not a part of bacterial transcription.

Rest of the energy (ATP) get converted into form of heat energy.

Specifically, the energy held in glucose is converted to ATP during cellular respiration. TheThe molecular energy the cell can use is called ATP, or adenosine triphosphate. It is the substance that gives your cells the power they need to carry out tasks like contracting your muscles as you stroll down the street.
A mole of glucose can be completely oxidised to produce about 670 kcal of energy. However, this mechanism only produces 36–38 ATP. About 7.4 kcal of energy are stored in each ATP molecule.
As a result, 38 x 7.4 = 281.2 kcal of energy is kept in the shape of ATP.
The amount of energy produced from the combustion of one mole of glucose is only 42%. While we sleep, 58% of our energy is discharged as heat, helping to keep us warm.

The collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis, is called the genetic code.

The genetic code is essentially a set of rules that specifies how the information encoded in DNA is translated into proteins. The code consists of 64 possible codons, each of which codes for one of the 20 amino acids used to make proteins.

The genetic code is highly conserved, meaning that it is virtually the same in all living organisms, from bacteria to humans. This universality of the genetic code is what allows scientists to transfer genetic material between different species and even kingdoms of life.

The genetic code is read by the ribosome, a complex molecular machine that translates the mRNA sequence into a specific sequence of amino acids that make up the protein. The process of protein synthesis is highly regulated and controlled, and any errors in the genetic code can result in serious consequences, such as genetic disorders or diseases.

ANSWER:

Adaptability

Environental tolerance

Reproductive rate

Shell Structure

Diet Flexibility

EXPLANATION:

Adaptability: Forams that were able to adapt to the changing conditions during the K-T event had a better chance of surviving. The event caused a sudden drop in temperature, acidification of the ocean, and other major changes. Forams that were able to adjust their feeding habits or change their shell composition to withstand the new conditions were more likely to survive.

Environmental Tolerance: Forams that could live in a variety of different environments were more likely to survive the K-T event. Some forams live in shallow water near the coast, while others live in deeper water. If one environment was wiped out, forams that could live in other environments had a better chance of surviving.

Reproductive Rate: Forams that had a high reproductive rate were more likely to survive the K-T event. This is because they were able to produce more offspring, increasing the likelihood that at least some of them would survive.

Shell Structure: Forams that had stronger and more resilient shells were more likely to survive the K-T event. This is because the event caused massive wildfires and tsunamis, which would have put a lot of stress on the shells of these organisms. Forams with stronger shells would have been better able to withstand these stresses and survive.

Diet Flexibility: Forams that had a more flexible diet were more likely to survive the K-T event. The event caused a major disruption in the food chain, which meant that forams that could eat a wider variety of food sources had a better chance of surviving.

Answer:

Explanation:

To calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest, we need to use the following formula:

exercising - resting = increased blood flow

Substituting the given values, we get:

exercising - resting = increased blood flow

exercising - 1,200 cm³/minute = 4.CC

To solve for exercising, we need to isolate the variable on one side of the equation. Adding 1,200 cm³/minute to both sides, we get:

exercising - 1,200 cm³/minute + 1,200 cm³/minute = 4.CC + 1,200 cm³/minute

exercising = 4.CC + 1,200 cm³/minute

Therefore, the equation to calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest is:

exercising = 4.CC + 1,200 cm³/minute
