A woman with normal blood clotting ability whose father was a hemophiliac and whose mother was normal with no family history of hemophilia marries a man whose blood has normal clotting ability. Recall that hemophilia is an X-linked trait. What is the probability that their first child will be a son with hemophilia
Answer:
The answer is 25%.
Explanation:
Hemophilia is a recessive illness that is x-linked.
If the husband has normal clotting ability, that means he has the dominant gene since he has only one X chromosome.
Since there is a probability that their child will have hemophilia, this means that the woman, who has 2 X chromosomes but has normal blood clotting abilities, has one dominant and one recessive hemophilia gene.
The probability that their first child will be a male is 50% and the probability that he will have hemophilia is also 50% since he will only get the Y chromosome from the father and the mother has one dominant and one recessive.
So the probability that their first child will be a son with hemophilia is 25%.

How does a cell normally make a thermodynamically disfavored reaction go forward?
Answer:
by producing enzymes that catalyze non-spontaneous reactions
Explanation:
Thermodynamically disfavored reactions can be referred to as nonspontaneous reactions (ΔG > 0). An enzyme is a catalyst molecule (generally proteins) capable of converting a non-spontaneous reaction into a spontaneous reaction and improve the speed of one chemical reaction in the cell. Enzymes are capable of reducing the energy of the transition state of a chemical reaction (rate of the reaction), thereby modifying the kinetics of a reaction.

The presence of a transit sequence directs a protein from the ________ to the ________. The presence of a transit sequence directs a protein from the ________ to the ________. signal recognition particle; nucleus cytosol; plasma membrane endoplasmic reticulum; Golgi apparatus endoplasmic reticulum; nucleus cytosol; mitochondrion or chloroplast
Answer:
The correct answer is "nucleus cytosol; mitochondrion or chloroplast".
Explanation:
A transit sequence, also known as signal peptide, in a protein is a series of amino acids that indicate that a protein is not synthesized matured, and a portion of the protein must be cleaved in order to have the protein in its mature form. Transit sequences serves as regulators of protein transport, since they indicate that a protein must transit from the nucleus cytosol to different organelles, such as the mitochondrion or chloroplast. Examples of this type of proteins, include: alcohol dehydrogenase, DNA polymerase, and RNA polymerase.
We are trying to determine the possible modes of inheritance for some particular human disorder. We have a very small pedigree for this disorder. Assuming the pedigree is accurate, indicate which of the modes of inheritance are consistent with this pedigree:
Answer:
The correct choices will be "X-Linked Recessive".
Explanation:
The heritage couldn't predominate because it would not be prevalent or observable in every decade at least. This could be a recessive gene, then. It would be a recessive condition related to X as it affects only individuals (male).X-Linked succession characteristics measured by chromosome-transported alleles become responded to although the X-linked.Which is a true statement regarding metastasis? Increased cell-to-cell adhesion helps metastasis. Lack of proteases and collagenases aids in metastasis. Cells must first escape the basement membrane of tissue. Penetration of the basement membrane of the vessel occurs first.
Answer: The correct answer to the question is option C
CELLS MUST FIRST ESCAPE THE BASEMENT MEMBRANE OF TISSUES.
Explanation: For any tumour cell to be able to gain entry into the lymphatic circulation or into the blood,there must first be an escape of the tumour cell from the basement membrane of the tissue it originated from,when the tumor first moves out if the basement membrane,it further moves through the extracellular space and then finds its way to the basement membrane of the vessel.
Spread of the tumour cells from it's point of origin (metastasis) is thought to involve the loss of cell to cell adhesion proteases and collagenases digestion of the basement membrane.
The basement membrane of the vessel can only be penetrated only if and after the basement membrane of the affected organ has been affected/breached.
A sample of a rare metal weighs 18.15 g. Several labs weigh the sample repeatedly. Which lab has the most precise measurements? A. Lab 1: 17.99 g, 18.15 g, 18.23 g B. Lab 2: 18.1 g, 18.3 g, 18.2 g C. Lab 3: 18.11 g, 18.13 g, 18.97 g D. Lab 4: 18.93 g, 19.03 g; 18.95 g
Answer:
D. Lab 4
Explanation:
Measurements in scientific experiments require the collection of data. The precision of a measurement refers to how close a measurement value is to one another.
N.B: The accuracy of a measurement is different from the precision. Accuracy is how close the measured values are to the true value.
To calculate the precision of measured values in different labs for a weighed metal, we use the range of values i.e. the difference between the highest value and lowest value for each lab.
Lab 1: 17.99 g, 18.15 g, 18.23 g
Range= 18.23 - 17.99 = 0.24
Precision result (mean±range)= 18.12±0.24
Lab 2: 18.1 g, 18.2 g, 18.3 g
Range= 18.3 - 18.1 = 0.2
Precision result: 18.2±0.2
Lab 3: 18.11 g, 18.13 g, 18.97 g
Range= 18.97 - 18.11 = 0.86
Precision result: 18.40±0.86
Lab 4: 18.93 g, 18.95 g, 19.03 g
Range= 19.03 - 18.93 = 0.1
Precision result: 18.97±0.1
Based on the range of values in the precision results from each lab, it is evident that Lab 4 has the most precise measurements because the repeated values didn't vary much from one another compared to values from other labs.
What is the pH of a 0.00125 M HCl solution?
Answer:
[tex]pH=2.9[/tex]
Explanation:
Hello,
In this case, the pH is computed by:
[tex]pH=-log([H^+])[/tex]
Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:
[tex]pH=-log(0.00125)\\\\pH=2.9[/tex]
Regards.
By definition, the pH of a 0.00125 M HCl solution is 2.90.
You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.
On the other side, a strong acid is an acid that dissociates completely in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid is equal to the concentration of hydrogen ions (Hydronium or H₃O⁺).
In this case, HCl is a strong acid. Then: [HCl]= [H⁺]= 0.00125 M
Reeplacing in the definition of pH:
pH= - log 0.00125 M
Solving:
pH= 2.90
Finally, the pH of a 0.00125 M HCl solution is 2.90.

O intermediate inheritance
O recessive inheritance
Answer:
The correct answer is - intermediate inheritance.
Explanation:
Incomplete dominance is type of inheritance pattern tat takes place when the phenotype or the alleles of the two parents blend together to form a new phenotype in next generation.
The alleles that can be dominant or recessive from each parent blend together to creates and expressed in mixed phenotype. An example is a white flower and a red flower cross to form pink flowers.
Thus, the correct answer is - intermediate dominance.

What work did Francis Bacon do with the design and organization of libraries ?
The correct answer to this open question is the following.
What Francis Bacon did with the design and organization of libraries was that he created a classification for books and texts, that served as an influence for the way big libraries, such as the Library of Congress classifies books.
Francis Bacon (1561-1626) classified his books into three categories: reason, memory, and imagination. This system was first copied by antifederalist politician Thomas Jefferson to organize his library. In the end, Thomas Jefferson developed a big catalog with 44 categories. That is how Francis Bacon influence the design and organization of libraries.

You collect a specimen from a deep jungle survey. It appears to be a new species. You get to name it, but before you can, you must classify it first. It appears to be single celled, and contains chloroplasts. When a few of them are kept in the dark too long, they die. Under the microscope you can see a dark colored nucleus. What classification fits them best?
Answer:
This question is incomplete/lacks options, the options are:
A) Plant-like protists
B) Plants
C) Fungus
D) Archeaebacteria
The answer is A) Plant-like protists
Explanation:
Organisms of the kingdom protista are eukaryotic (possess a membrane-bound nucleus) unicellular or multicellular organisms that can be autotrophic or heterotrophic in nature depending on whether they are plant or animal like. Protists are classified borganisms that do not fit into the other group classification i.e. fungi, plant, animal and bacteria.
However, organisms in the group called PROTISTS can either be animal-like or plant-like depending on whether they possess some animal or plant characteristics respectively. Plant-like protist, like the organism described in the question, have CHLOROPLAST organelles like plants and hence, can perform photosynthesis in the presence of sunlight to synthesize their own food. This characteristics makes them autotrophic like plants.
Therefore, based on the characteristics of the new specimen collected from a deep jungle survey, the classification that fits it best is PLANT-LIKE PROTISTS.

Which one of these can be rearranged into a type of flower? A. FSNWOLRUE B. LBANEQUT C. NRABE D. VLEBQA
Answer:
flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross pollination or allow selfing (fusion of sperm and egg from the same flower) when self pollination occurs.
Pollination have two types which is self-pollination and cross-pollination. Self-pollination happened when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happened in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower’s stigma. This pollination does not require an investment from the plant to provide nectar and pollen as food for pollinators.[1]
Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds.
In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to bring beauty to their environment, and also as objects of romance, ritual, religion, medicine and as a source of food
