Why doesn’t the chromosome number double every time a new generation is formed?
Answer:
Mitosis
Explanation:
Mitosis is the process of cell division. both daughter cells that come out of mitosis are duplicates of eachother. the chromosomes split so each cell has the same amount as the parent cell. thus, the chromosomes do not double.

fungi differ from plants in that they do not reproduce by seeds and lack called_____-
Fungi differ from plants in that they do not reproduce by seeds and lack structures called "roots."
Fungi lack true roots. Instead, they possess a network of branching, thread-like structures called hyphae. Hyphae penetrate through organic matter, such as soil, decaying material, or living organisms, allowing fungi to extract nutrients. This mycelium (mass of hyphae) acts as the primary feeding structure of fungi. It absorbs nutrients from the surrounding environment, breaking down complex organic compounds into simpler forms that can be utilized by the fungus.
While some fungi form mutualistic relationships with plants, such as mycorrhizal associations where fungal hyphae extend into plant roots, these structures are not roots in the same sense as those found in plants. They serve different functions and have distinct anatomical and physiological characteristics.

a 12-year-old cat is equivalent to a _______-year-old human.
Based on the guideline, a 12-year-old cat would be approximately equivalent to a 64-year-old human.
There is no precise equivalence between the age of a cat and a human, as the aging process differs between species. However, a commonly referenced guideline is that the first year of a cat's life is roughly equivalent to 15 human years. After that, it's generally estimated that each additional cat year is equivalent to around 4 human years.
Based on this guideline, a 12-year-old cat would be approximately equivalent to a 64-year-old human. However, it's important to note that this is a rough estimation and individual factors such as genetics, lifestyle, and health can influence the aging process in both cats and humans.
In general, it is often stated that the first year of a cat's life is equivalent to around 15 human years in terms of aging. After that, the rate at which a cat ages slows down compared to humans. It is commonly estimated that each additional cat year is roughly equivalent to about 4 human years.

You are recruiting 10 space-travelers to populate a new planet many light-years away. The travelers will need to be cryogenically frozen and to fit in the cryogenic pods they will need to be between 170cm and 190cm tall. Amongst the species to which you belong height can be approximated by a normal distribution with a mean of 178cm and a standard deviation of 5cm. What is the probability that a randomly selected potential traveler will fall within the permitted height range? What is the probability that a randomly selected group of 10 travelers will all be within the permitted height range? The maximum total weight of the 10 travelers must not exceed 500kg meaning that their average weight should not be above 50kg. If individuals' weight is described by a normal distribution with a mean of 48kg and a standard deviation of 3kg what is the distribution of the mean weight of a sample of 10? What is the probability that a randomly chosen group of 10 travelers is underneath the weight limit? A colleague of yours suggests that to get the overall probability of a group of 10 travelers meeting both the height and weight constraints you should multiply the probability in (b) with the probability in (d). Do you agree? Why or why not?
(a) The probability that a randomly selected potential traveler will fall within the permitted height range is approximately 68.27%.
(b) The probability that a randomly selected group of 10 travelers will all be within the permitted height range is approximately 23.76%.
(c) The distribution of the mean weight of a sample of 10 travelers follows a normal distribution with a mean of 48kg and a standard deviation of 0.95kg.
(a) To calculate the probability that a randomly selected potential traveler will fall within the permitted height range, we need to find the area under the normal distribution curve between the heights of 170cm and 190cm. Using the properties of the normal distribution, we can calculate that approximately 68.27% of the population falls within one standard deviation of the mean. Therefore, the probability that a randomly selected potential traveler will fall within the permitted height range is approximately 68.27%.
(b) To calculate the probability that a randomly selected group of 10 travelers will all be within the permitted height range, we need to calculate the probability of each traveler falling within the range and then multiply those probabilities together. Since each traveler's height is independent of the others, the probability that a single traveler falls within the range is approximately 68.27%. Therefore, the probability that all 10 travelers fall within the range is approximately (0.6827)^10, which equals approximately 23.76%.
(c) The distribution of the mean weight of a sample of 10 travelers follows a normal distribution with the same mean as the individual weights (48kg) but a standard deviation that is the original standard deviation (3kg) divided by the square root of the sample size (10). Therefore, the standard deviation of the mean weight of the sample is 3kg/sqrt(10) ≈ 0.95kg.

When you reach the end of the mRNA strand in your modeling of the translation process, describe what has happened to the polypeptide. 23. What external stimuli helps direct the ribosome/mRNA complex to the ER receptor?
When the ribosome reaches the end of the mRNA strand during the process of translation, the polypeptide chain has been fully synthesized. The ribosome releases the polypeptide from the mRNA and dissociates from the mRNA molecule.
In eukaryotic cells, the polypeptide may undergo further modifications and folding to attain its functional conformation. It may be targeted to specific cellular compartments, such as the endoplasmic reticulum (ER), for further processing or secretion.
The direction of the ribosome/mRNA complex to the ER receptor is facilitated by a signal sequence present in the growing polypeptide chain. This signal sequence is recognized by a signal recognition particle (SRP), which is a complex of proteins and RNA. The SRP binds to the signal sequence and guides the ribosome/mRNA complex to the ER membrane, where it interacts with the ER receptor. This process is known as co-translational translocation and ensures that proteins destined for the ER or secretory pathway are properly targeted and inserted into the ER membrane.

if pp purple plants are crossed with pp white plants, what will be the possible combinations of factors if the f1 generation is allowed to self-pollinate?
The possible F1 generation combinations are Pp Purple plants and Pp White plants.
What is self-pollination?
Self-pollination is a form of pollination where the male reproductive cells, or pollen, of a plant are transferred to the female reproductive cells of the same plant. This process usually occurs in plants that produce flowers, and it occurs when the pollen from the anther, the male reproductive organ of a flower, is transferred to the stigma, the female reproductive organ of the same flower. Self-pollination allows a plant to produce offspring that closely resemble both parent plants.
The possible combinations of factors in the F1 generation if the purple plants and white plants are crossed and allowed to self-pollinate are:
PP Purple plants x PP White plants
F1 Generation:
Pp Purple plants – This would be the dominant purple phenotype, with a purple flower and a white plant genotype.
Pp White plants – This would be the recessive white phenotype, with a white flower and a purple plant genotype.
Therefore, Pp Purple plants and Pp White plants is the possible combinations of factors if the f1 generation.

In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles
Answer:
The correct answer is - increase: constriction of the arterioles.
Explanation:
When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.
It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.

In the 1940s and 1950s, Dr Barbara McClintock studied mosaic colour patterns in corn and discovered their unstable inheritance and the underlying mechanisms. In 1983 she was awarded the Nobel Prize in Physiology/Medicine for her discovery, and is now considered one of the most influential geneticists of the 20th century. (a) Name two synonymous names for the genetic elements that Dr McClintock discovered
(b) What can these genetic elements do, and what can the consequences be for a gene and for a host genome?
(c) Which gene function do these elements require for their activity, and what are the two classes that these elements can be assigned to, and how do these two classes function in a host genome? (d) Why did Dr McClintock initially find resistance to publish her findings and in the scientific community, to the point that she did not publish these for 20 years, and why were her ground-breaking research findings a paradigm shift in the end?
They are known by two synonymous names: transposable elements or transposons. These elements can move within a genome and have various consequences for a gene and the host genome.
(a) The two synonymous names for the genetic elements discovered by Dr. McClintock are transposable elements and transposons. These terms refer to segments of DNA that have the ability to move or transpose within a genome.
(b) Transposable elements can have various effects on genes and the host genome. They can insert themselves into a gene, disrupting its function and causing mutations. They can also influence gene expression by inserting near regulatory regions, affecting the level of gene activity. Additionally, transposable elements can cause genomic rearrangements, such as duplications, deletions, or inversions, altering the structure of the genome.
(c) The activity of transposable elements requires specific genes called transposase genes. Transposase enzymes catalyze the movement of transposable elements within the genome. Transposable elements can be classified into two main classes: Class I retrotransposons and Class II DNA transposons. Class I retrotransposons transpose via a copy-and-paste mechanism, where the element is first transcribed into RNA, then reverse transcribed back into DNA and inserted at a new location. Class II DNA transposons, on the other hand, move through a cut-and-paste mechanism, directly excising from one genomic location and reinserting into another.
(d) Dr. McClintock initially faced resistance and skepticism from the scientific community, which led her to withhold publishing her findings for nearly 20 years. At the time, the prevailing belief was that genes were fixed entities with stable positions in the genome. Dr. McClintock's discovery of mobile genetic elements challenged this view and was initially met with skepticism.
