Red-flowered snapdragons are crossed with white-flowered snapdragons, producing all pink snapdragons in the F1 generation. What would you expect if you crossed pink with pink? The choices are... (1/2, 1/4, 3/4) red, (1/2, 1/4, 3/4) pink, (1/2, 1/4, 3/4) white.
Answers
Answer:
Red (1/4), Pink (1/2), white (1/4)
Explanation:
This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).
The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.
Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.
RR offsprings (1/4)- Red flowered
RW offsprings (2/4 or 1/2)- Pink flowered
WW offsprings (1/4)- White flowered

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy?
Answers
Answer:
The probability of a cross between RRYY x RrYy to generate a yellow and wrinkled seed offspring is 0%.Explanation:
Circular and yellow seeds are overwhelming and wrinkled and green seeds are passive. It is vital to keep in mind that resective characteristics are as it were displayed when the sibling has two passive alleles for those characteristic, in the event that the descendant includes a latent allele and a overwhelming allele, the characteristic that will be presented is the overwhelming one. For this reason, able to say that a cross between RRYY x RrYy plants, would not create any descendant with wrinkled and yellow seeds. Typically since, the descendant of a crossing, must show an allele of each parent. One parent as it were has overwhelming alleles (RRYY), so able to say that all descendant will get 1 overwhelming allele for color and a overwhelming allele for seed surface, anticipating the sibling from communicating latent characteristics.

Which statement accurately describes tectonic plate movement? Tectonic plate movement can be prevented with planning. Tectonic plate movement does not cause environmental change. Tectonic plate movement does not affect organisms. Tectonic plate movement is a long-term environmental change.
Answers
Answer:
The correct answer is Tectonic plate movement is a long-term environmental change.
Explanation:
When tectonic plates in the earth started to move, this process helped the planet to evolve and to shape the continents as exist today.
Different investigation teams have discovered that plates move approximately 2.5 centimeters per year. This movement is the key to the evolution of life and the development of the planet. This slow process involves mountain formation, rocks exposure, and chemical reactions that could stabilize the temperature on the earth´s surface for millions of years. And this stable weather is essential for the evolution of life. Plates movement carries carbon inside and outside of the planet, regulating the amount of carbon dioxide in the atmosphere (greenhouse effect). In this way, it can regulate the temperature. This regulation influence in precipitations, chemical reactions that involve carbon release and minerals such as calcium, the water flow, volcanic eruptions, among other events. Plates tectonic is also responsible for life, as weathering and mineralization of the rocks release elements and nutrients that are necessary for the life of different organisms.
So, up to this point, we can say that tectonic plates movement can not be prevented with planning, it does cause environmental change by regulating temperature, and hence it affects organisms.
There are short term effects and long term effects provoked by tectonic plates movement. Earthquakes are examples of short term effects, while mountain formation, ocean formation and, clime regulation are examples of long term changes.
Plates tectonic movement is a very slow process, that might last many years. The Andes formation, for example, started approximately 200 years ago, and these mountains are still rising. The subduction process has not finished as the plates are still moving.

The cell cycle describes the processes that take place as a cell Your answer: A.forms new cells. B.absorbs nutrients. C.makes proteins.
Answers
Answer:
Choice A
Explanation: This is because the main purpose of the cell cycle is to create new cells for the organism via mitosis or meiosis.
The cell cycle illustrates the procedures, which occurs as a cell produces new cells.
What is cell cycle?It refers to a series of events, which occurs in a cell as it grows and differentiates.
A cell devotes majority of its time in the phase known as interphase, and during this time it develops, divides its chromosomes, and prepares for the division.
After that the cell leaves interphase, and goes through the process of mitosis, and completes the process of division.
It can be said that the prime task of cell division is to produce novel cells.
Thus, the correct answer is option A, that is, forms new cells.

What are 10 thing that classify as a Secondary succession?
Answers
Answer:
The renewal of a forest after a fire: The fire itself destroys a majority of different types of trees and plant life. Because seeds and roots and other plant and tree parts remain in and on the soil, gradually the plants and trees begin to grow again and eventually returns to the state of the original ecosystem.
The renewal of a crop after harvesting: Without new seeds being planted, the crop can regenerate the following year due to the plants and seeds that remained after harvesting.
A forest renews after logging: Lots of trees were chopped down by loggers to create building materials. Over time, trees grow in and the area returns to its previous state.
A volcanic eruption: In an area where a volcano erupts, lava may cause some damage to the plant and tree life. Over a span of years, however, if there was land that had been affected by the eruption but not necessarily covered in new volcanic rock, the seeds and plant parts and roots in the soil could renew.
On the island of Lawahii, several centuries ago, a fire erupted that caused the destruction of all plants and vegetation. Many years later, the plants and vegetation had grown back in, as the nutrients, seeds and soil remained.
Renewal after disease: A plant population can be very negatively affected by a variety of infectious plant diseases. If the entire population dies, but the soil and roots remain, it is possible for secondary succession to occur and for the population of those plants to to return.
A flood can ruin farmlands. However, because the soil remains after the waters recede, over the course of many years a natural secondary succession can occur and the vegetation that had previously grown there can grow again.
Plants can be very susceptible to attack from pests, particularly if there is an overpopulation of those pests. When this occurs, the plant population in one area can be completely destroyed. However, when the pest overpopulation is resolved, the plants are able to live again and thrive in the soil in which they previously had lived.
Potato scab is a tuber disease that grows on potatoes. If this disease affects a large amount of potatoes, the potatoes may not grow or may be harvested and thrown away. Over time, once the disease has been eradicated, healthy potatoes can grow again.
And also human activities can harm the environment and cause secondary secession.

Which of the following statements is correct? (1) Translation always begins with an AUG start codon. (2) The start codon establishes the reading frame of mRNA. (3) The mRNA molecule is read one codon at a time until a stop codon is reached.
Answers
Answer:
1, 2 and 3
(1) Translation always begins with an AUG start codon.
(2) The start codon establishes the reading frame of mRNA.
(3) The mRNA molecule is read one codon at a time until a stop codon is reached.
Explanation:
Translation is the second stage of the gene expression process which involves the synthesis of amino acid sequence (protein) from an mRNA transcript. During translation, the nucleotide sequence are read in a group of three nucleotides called CODON. The codon are found on the mRNA molecule and each one specifies an amino acid.
Translation starts with a start codon, which is AUG coding for methionine. Due to the fact that translation will start with an AUG codon, it automatically sets the reading frame of the mRNA molecule i.e. the pattern the mRNa will be read during translation. The start codon (AUG) determines how the reading frame will progress considering it is read first or initiates the translation process.
Translation continues in the RIBOSOME, where each codon is read by the tRNA one at a time until a stop codon is encountered. A stop codon signals the end of the translation process, and releases the peptide sequence. The mRNA stop CODON specifies no amino acid and are UAG, UAA, and UGA.

Hemophilia is a sex-linked recessive trait in humans. If a father and a son are both hemophiliacs, but the mother is normal, her genotype must be____. (Note: the H's are superscripts.) * XhXh XHXh XHXH XhY
Answers
Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)
In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.
XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.

Which phylum is a group of miscellaneous fungi that don’t fit into the other three categories? Zygomycotes Deuteromycotes Ascomycotes Basidiomycotes
Answers
Answer:
Deuteromycotes
Explanation:
Kingdom Fungi consist of eukaryotic organisms grouped into 3 phyla, with one group that doesn't fit into any of the grouped three. Each group of fungi were classified into phylum based on their reproductive life cycle. The three phyla are Zygomycotes, Ascomycotes, Basidiomycotes.
Zygomycotes produce their spores by meiosis in a structure called Zygosporangium. Ascomycotes produce their spores via meiosis in ascus (sac-like). Basidiomycotes produce their own spores via meiosis in club-like basidium.
However, a fourth group exists that has no known sexual reproductive structure (meiospores), instead it is known to reproduce asexually via mitospores. This group is called DEUTEROMYCOTES or commonly known as FUNGI IMPERFECTI. It is a group of miscellaneous fungi that doesn't fit into the classification basis of the other three phyla.
Which of the following is used as cellular support for cells and unicellular organisms?
A) chloroplasts
B) lysosomes
C) endoplasmic reticulum
D) microtubules
Answers
Answer:
D. Microtubules
Explanation:
Microtubules are made of proteins (largely) that make up a cell's cytoskeleton, which provides the internal support framework for the cell.
The correct option is, (D) microtubules.
The cytoskeleton of a cell, which provides the internal support structure for the cell, is primarily made up of proteins, which are the building blocks of microtubules.What is the function of the endoplasmic reticulum?In general, the endoplasmic reticulum's job is to make proteins so that the remainder of the cell can operate. It can be smooth or rough. Ribosomes, which are tiny, elongated organelles with a round shape, are found on the rough endoplasmic reticulum and are responsible for producing those proteins.Which of following organelles help with cellular movement?The cytoskeleton not only performs this structural function, but it also controls how cells move. These involve not just the internal movement of organelles and other structures (such mitotic chromosomes) through the cytoplasm, but also the motions of whole cells.Which organelle provides energy for the cell?Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).Hence, microtubules is used as cellular support for cells and unicellular organisms.
