BB = normal blood clotting
Bb = carrier for hemophilia
bb = hemophiliac
Because the mother does NOT have hemophilia, we will be using BB x Bb to find out the alleles of their children. Because this is sex-linked traits practice, our alleles will be the following.
normal = X^BY
(uppercase B represents no hemophilia)
X^BX^b
Let’s cross them and see what we get!
X^B Y
X^B | X^BX^B X^BY
X^b | X^BX^b X^bY
As you can see, 0/4 of the females (represented by XX) will have hemophilia. Again, it is only present when there are two recessive alleles and none of them satisfy that.
2/4 of the females will be carriers (X^BX^b).
As for the boys, 1/4 will have normal clotting and 1/4 will have hemophilia. None of the males will simply be carriers.

Which statement about human population growth is least likely to be correct
Answers
Answer:
Technological advances in farming and medicine will allow human populations to continue to grow without natural limits.
Explanation:
Technological advances in farming and medicine will allow human populations to continue to grow without natural limits. Thus, the correct option is C.
What is Human population growth?Population growth is the increase in the total number of humans on the Earth. For most of the human history, the population size was relatively stable for time. But with the innovation and industrialization, energy, food, water, and the medical care became more available and reliable.
The logistics population growth has been represented through the help of the logistic growth curve on a line graph and the shape of the curve is a S-shaped curve which represents slow increase, and rapid growth in the population and after which there has been reduction in the growth.
The best example of the logistics growth has been observed in the wild population which has been included in the sheep as well as harbor seals. In both of the cases, the number of population increases and the carrying capacity for small period of time.
Therefore, the correct option is C.

Which characteristic is expected of a mineral that crystallizes from lava at Earth’s surface
Answers
Answer:
Small crystals mark me brainiest
Explanation:
i would've passed if he gave me the right answer
A discerning characteristic expected of a mineral that crystallizes from lava at Earth’s surface is that it becomes an igneous rock, like basalt or potentially an amorphous solid like glassy silica if the cooling process is rapid.
Explanation:A characteristic expected of a mineral that crystallizes from lava at Earth’s surface is that it forms an igneous rock. A perfect example of this is basalt, which is produced by the cooling of lava and comprises most of Earth's oceanic crust. If the cooling process is rapid, as with molten silicon dioxide (SiO₂), it can yield an amorphous solid (non-crystalline), known as 'fused silica' or glassy silica.
Basaltic rock is marked by holes left by gas bubbles, a distinctive feature of rock formed from lava. In the case of silicon dioxide, when it cools off from a liquid state, it usually becomes supercooled and turns into a glass, a state characterized by the random arrangement of SiO₄ tetrahedra. This material is highly resistant to rapid temperature changes, which is why it does not fracture easily.

What does DNA provide the code for?
Answers
Answer:
The correct answer will be proteins and essential molecules.
Explanation:
DNA is made up of sugar, a phosphate group and nitrogenous bases. These nitrogenous bases are read by the ribosomes during translation in a group of three bases called "triplets or codons". These codons provide the instructions for the synthesis of proteins as each codon codes for amino acids which make up a protein when bonded.
Thus, proteins and essential molecules are the correct answer.

B. To identify areas of high and low water vapor
C. To differentiate between seasons
D. To provide estimates for the amount of direct sunlight received
Answers
Answer:
A. To identity high- and low-pressure systems
Explanation:
Isobars are similar to the level lines on a topographic map, showing areas of similar pressure, they are also drawn in circles to represent the areas of similar air pressure over a geographical map.
Isotherms are usually displayed in color showing areas over a map that have the same temperature or are covered by a similar temperature system (heat or cold front for example).
Both are used in electronic media mostly (although in print in newspapers too), over a geographic map to position the systems.
If 30% of the bases in a particular DNA molecule are guanine(G), what percentage of the bases would be thymine(T)? Explain your reasoning.
Answers
Since 30% of the bases are guanine, we know that 30% must also be cytosine (because it pairs with guanine in DNA).
Knowing this, we have figured out 60% out of 100%, leaving us with 40%.
Thymine pairs with Adenine, so Thymine and Adenine each make up 20% of the remaining 40% of the DNA in this example.
In total:
Guanine: 30%
Thymine: 20%
Cytosine: 30%
Adenine: 20%
Percentage of thymine will be 20%
Deoxyribonucleic acid (DNA) is a double stranded molecule and one of the two types of nucleic acids. It is made up of nucleotides subunit namely: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).Adenine (A) pairs with Thymine (T) while Guanine (G) pairs with Cytosine (C) in the DNA molecule. According to Chargaff in his rule, the amount of all four bases equals to 1 i.e.A + G + C + T = 100% or 1
In a DNA molecule, Adenine = Thymine and Guanine = Cytosine. This means that the amount of adenine and thymine is equal and the same goes for cytosine and guanine. According to this question, If 30% of the bases in a particular DNA molecule are guanine(G). This means that the percentage of its pair (Cytosine) will also be 30%.That is;
A = T + G = C = 100%
A + T + (30 + 30) = 100
A + T + 60 = 100
A + T = 40
T = 40/2 = 20%
Hence, the percentage of thymine and adenine will be 20% each.

An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3. What is the estimated mass of the atom.
Answers
Answer: Answer choice B . 70 (35 protons + 35 neutrons)
Explanation:
Answer:
The estimated mass of the atom is 70 amu
Explanation:
An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3.
Mass of an atom is equal to the sum of number of protons and number of neutrons.
In this case, number of protons p = 35
Number of neutron n = 35
So, the estimated mass of the atom will be :
[tex]M=35\ protons+35\ neutrons=70\ amu[/tex]
Hence, this is the required solution.

n-1 would be the answer :)
Explanation:
Answer:
Monosomy could be descrided as 2n-1
Explanation:
Monosomy is the lack of one member of a chromosome pair. It is as a result of nondisjunction during meiosis. When this happens, one gamete shows monosomy, and the other shows trisomy of the same chromosome.
A diploid cells (2n) is characterized by the presence of two copies of each chromosome versus haploid cells (n). Therefore, monosomy could be descrided as 2n-1.

Plant food made by photosynthesis consists of:
A) sugar
B) chlorophyll
C) starches
D) carbon dioxide
Answers
Answer:
A) sugar
C) starches
Explanation:
Sugar is produced in the form of glucose
Glucose is used to make cellulose fibers, the structural component of the plant, or is stored in the form of starch granules
Plant food made by photosynthesis consists of sugar and starches, which are produced by plants from glucose. Chlorophyll is involved in capturing light, not a product. Carbon dioxide is a reactant, not a product of the process.
Explanation:During photosynthesis, plants manufacture food primarily in the form of glucose, which is a type of sugar. This sugar is later used by the plant to produce various organic materials, such as starches, which are also products of photosynthesis and are stored for later use. However, chlorophyll is a pigment involved in the capture of light energy and is not a product of photosynthesis. Moreover, carbon dioxide is a reactant in the photosynthetic process, not a product. Therefore, the correct answers indicating plant food made by photosynthesis are A) sugar and C) starches.
The plant food made by photosynthesis consists of sugar, starches, and oxygen. During photosynthesis, plants use the energy from sunlight to combine carbon dioxide and water, resulting in the production of glucose (a sugar) and oxygen. Glucose can be further converted into starch for storage.

Differentiation converts a small ball of different type of cells into a multicellular, nonfunctional, well-organized organism. B. Differentiation converts a small ball of similar kinds of cell into a multicellular, multifunctional, well-organized organism. C. Differentiation converts a single cell into a mass of similar type, multifunctional cells.
Answers
Answer:
B
Explanation:
An undifferentiated cell is such as that in a blastocyte. They are multipotent and can differentiate into any type of cells. The cells of the mass begin to have their gene differentially expressed (due to differential silencing of particular genes) hence the cell become determined. They become well organized into tissue such as skin and other organs.
B. Differentiation converts a small ball of similar kinds of cell into a multicellular, multifunctional, well-organized organism.
Explanation - Differentiated cells are the cells that are bound to play out a particular capacity in the body i.e., they have turned out to be specific. These cells don't be able to change to play out another capacity.
During cell separation, the phone experiences an adjustment in quality articulation. So as to play out its capacity, the cell produces explicit proteins. Case of a separated cell is the liver cell, platelet, and so on.

B. Chocolate chips baking in cookies
C. Simmering soup on the stove
D. Peanut butter cooking baking
Answers
i think the answer is b
The best analogy for the universe's expansion is chocolate chips baking in cookies. This is because as the dough expands when heated, the chips (galaxies) move further apart just like the galaxies in the universe are moving farther apart as the universe expands. It aligns with the Big Bang Theory and the cosmological principle.
Explanation:The expansion of the universe can be compared to chocolate chips baking in cookies (B). Imagine that each chocolate chip is a galaxy. As the cookie dough is heated, it expands and the chips (or galaxies) move apart from each other, much like how galaxies in our universe are moving away from each other as the universe expands.
This concept is based on the Big Bang Theory and the associated metric expansion of space, where the scale of space itself changes. This comparison helps us to understand the cosmological principle, which states that the universe, when viewed at a sufficiently large scale, looks the same no matter where you are observing from.
