In a unique species of plants, flowers may be yellow, blue, red, or mauve. All colors may be true-breeding. If plants with blue flowers are crossed to red-flowered plants, all F1 plants have yellow flowers. When these produced an F2 generation, the following ratio was observed: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve. Determine the F1 results of a cross between true-breeding red and true-breeding mauve flowered plants.

Answers

Answer 1

Answer:

F1) 100% bbRr, red flowered plants.

Explanation:

Available data:

flowers may be yellow, blue, red, or mauvecolors may be true-breedingthe cross of blue-flowered plants with red-flowered plants, produce plants that have yellow flowersF2 generation: 9/16 yellow, 3/16 blue, 3/16 red, and 1/16 mauve.

Knowing that the phenotypic ratio is 9:3:3:1, we can assume that there are two genes involved in the flower color expression. We can name these genes B and R with a dominant and a recessive allele each (B, b and R, r respectively).

According to the first cross, we might establish the following genotypes:

1st Cross: blue-flowered plant     x     red-flowered plant

Parentals)         BBrr                     x                bbRR

Gametes)     Br, Br, Br, Br                         bR, bR, bR, bR

F1) 100% BbRr, yellow plants

Parentals)   BbRr     x     BbRr

Gametes) BR, Br, bR, br

                BR, Br, bR, br

Punnett square)     BR       Br        bR          br

                  BR     BBRR    BBRr   BbRR     BbRr

                  Br      BBRr     BBrr     BbRr      Bbrr

                  bR     BbRR    BbRr    bbRR      bbRr                    

                  br      BbRr     Bbrr      bbRr      bbrr

F2)  9/16 yellow ---> 1/16 BBRR + 2/16 BBRr + 4/16 BbRr + 2/16 BbRR  

       3/16 blue ------> 1/16 BBrr + 2/16 Bbrr

       3/16 red---------> 1/16 bbRR + 2/16 bbRr

       1/16 mauve ----> 1/16 bbrr    

So,

Yellow-flowered plants: BBRR, BBRr, BbRR, BbRrRed-flowered plants: bbRR, bbRrBlue-flowered plants: BBrr, BbrrMauve-flowered plants: bbrr

According to these genotypes, the second cross would be like following,

2nd Cross: true-breeding red-flowered plants with true-breeding mauve flowered plants.                

Parentals)          bbRR       x        bbrr

Phenotype)       Red                   Mauve

Gametes)   bR, bR, bR, bR      br, br, br, br

Punnett square)    bR       bR        bR        bR                    

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

                    br    bbRr     bbRr    bbRr     bbRr

F1) 100% bbRr, red flowered plants.

Explanation:

The growth hormone is responsible for stimulating normal growth in humans or in other words, stimulating growth at a normal pace. To do this, the growth hormone must be released in optimal quantities, however, an hypersecretion i.e. excessive release of the hormone will cause a fast and uncontrollable growth in certain regions of their body or the whole.

This abnormal excessive growth caused by an excessive release of the growth hormone is called GIGANTISM. Gigantism occurs mostly in children at their growing phase.

Answers

It's budding or vegetative productioon it's one of them i think tell me if i am wrong

The type of asexual reproduction shown in the image below is Option C) Budding.

Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. For example, the small bulb-like projection coming out from the yeast cell is known as a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.

In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as Toxoplasma gondii. It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring before their separationBudding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species, buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas. The initial protuberance of proliferating cytoplasm or cells, the bud, eventually develops into an organism duplicating the parent. The new individual may separate to exist independently, or the buds may remain attached, forming aggregates or colonies. Budding is characteristic of a few unicellular organisms (e.g., certain bacteria, yeasts, and protozoans). However, a number of metazoan animals (e.g., certain cnidarian species) regularly reproduce by budding.

Explanation:

Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.

Answers

Answer:

A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes

Explanation:

The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.

Enzymes raise the activation energy needed in a chemical reaction

Enzymes slow down the rate of chemical reactions

Enzymes function best at specific pH and temperatures

Enzymes are carbohydrates and store short term energy

Answers

Answer:

Enzymes function best at specific pH and temperatures.

Explanation:

An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

Which is larger, 40 centimeters or 670 millimeters?​

Answers

Answer:

670 Millimeters

Explanation:

1 Millimeter = 0.1 Centimeter

670 millimetres is equal to 67 cm which is greater than 40 cm. So 670 mm is greater than 40 cm.

What is a millimetre?

It is a unit of measurement for length/distance. It is a very small unit of measurement. It is a visible unit of measurement, unlike a micrometre which is smaller than a millimetre but measures things that are not visible to the unaided eye.

It is a part of the metric system commonly used in Science, Technology Engineering and Mathematics (STEM). A millimetre is measured as one-thousandth of a metre.

The word metre is derived from a Greek word which means measure. The metric system that is used internationally for the measurement of various quantities is based on decimals.

Like a millimetre is one-thousandth of a metre, a micrometre is one-millionth of a metre. A centimetre is one-hundredth of a meter and a quantity smaller than a micrometre called a nanometer is one-billionth of a meter.

Therefore, 670 mm is 67 cm which is greater than 40 cm.

Adenine (A) = 28%

Cytosine (C) = 22%

Explanation:

The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.

According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.

In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:

(A + T) + (G + C) = 100%

A + T + 22 + 22 = 100

A + T + 44 = 100

A + T = 100 - 44

A + T = 56

Since A = T,

56/2 = 28

Hence, A = 28%, T = 28%

A Good Day for a Bad DecisionHave you ever noticed that some people always seem to make the right choices? They may be the person who always picks the right pitch to swing at, or the one who always picks the pair of shoes that quickly become a popular fad. On the other hand, some people never seem to make a good decision. They may be the kids who ride a bike down a steep hill and crash into a bush or the ones who step to the edge of a sidewalk in time to get splashed by a car. How do some always seem to be living the good life while others seem doomed to misery? Is this just a matter of luck?While luck probably has something do with it, the better explanation may be that the two groups have differences in the development of their brains. You see, most adult humans use their cerebral cortex to make decisions. The cerebral cortex is the part of the brain in the front of your head that deals with how you perceive the world and respond appropriately. It also helps you control your impulses. This part of the brain is still growing and developing connections well into your adult years. So for young adults and teenagers, the decision-making center of the brain is not completely formed yet.At the same time, the teenage brain is also experiencing growth in another part of the brainthe amygdala (a-mig-dala). This part of the brain is responsible for emotions. Specifically, the amygdala talks to other parts of the brain about events related to rewards and fear.In essence, our emotional brains are having growing spurts and our impulses are out of control at the same time our cerebral cortexes are not finished growing. We simply don't have the tools to control those emotions and impulses. As a result, teenagers feel overly emotional and wishy-washy when it comes to decisions. This development cycle is one reason society doesn't consider children to be adults until after they are 18. Biologically, the teenage brain is not generally ready for adult decisions.So the differences between those who seem to make good decisions and those who seem to make bad ones may be fewer than you think. In fact, if you study the people you think make only good decisions, you will likely find they also make some catastrophically bad ones as well. A person's ability to make a good decision increases with age and experience though we all develop at different rates. While you are young, you may want to take advantage of those around you with bigger cerebral cortexes: adults. Their advice may be just what is needed to counter your amygdala.Which line from the text best states the main idea of the text?
