Answer:
100% carrier daughter
Explanation:
Remember,
---> individuals with XX are always female
---> individuals with XY are always male
Therefore, if all of the female offspring are carriers, this means the odds that their daughter is a carrier is 100%.
1No.Answer:- The genes that can give you red-green color blindness are passed down on the X chromosome. Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother.
2No.Answer:- Each daughter has a 50% chance of being a carrier and each son has a 50% chance of being color blind. The daughters who are carriers can have color blind sons with the same logic.

What happens during telophase of the cell cycle?
Chromosomes are pulled apart.
Chromosomes condense.
Chromosomes uncoil and the nucleus reappears.
Chromosomes line up.
Answers
The telophase of the cell cycle chromosomes uncoil and the nucleus reappears. That is option C.
What is telophase?Telophase is a stage of the cell cycle that occurs once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
During the telophase stage, chromosomes arrive at opposite poles and unwind (uncoil) into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears.
Therefore, the telophase of the cell cycle chromosomes uncoil and the nucleus reappears.

In which layer is lithification most likely to occur?
Answers
Answer:
Lithification is the process by which sediment turns into hardened rock. There are three ways in which lithification can occur. These processes are called compaction, recrystallization and cementation. It happens mostly in the subsoil.
Explanation:
Lithification is most likely to occur in sediments on the bottom of the ocean or other bodies of water.
What do you mean by lithification?Lithification is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity destruction through compaction and cementation.
It refers to the process that loose and underconsolidated Sediment particles transform into hard and solid rocks. This process includes a number of geological processes, such as consolidation, deep bury, cementation, recrystallization and dehydration.
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

If different masses of water are heated to the same temperature, which sample will absorb more energy? Base your argument on the definition of heat and what you learned from the experiment.
Answers
If different masses of water are heated to the same temperature, the sample that will absorb more energy will be the mass of water with the greatest amount of water mass, because the larger the material, the greater the amount of heat needed.
What is the specific heat of water?Water has a specific heat of 1 cal/g. ºC This means that the energy of 1 cal is required for a variation of 1 °C in 1 g of water.
With this information, we can conclude that Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), has the unusual property that it either tastes very bitter or is virtually tasteless, depending on the genetic makeup
of the taster. There is a single gene which codes for a protein found in our tongues. PTC will bind with the protein if it present and a person will taste it. If the protein is not present,
PTC will not bind and a person cannot taste it. The ability to taste PTC is often treated as a dominant genetic trait. The dominant allele, T, causes a person to be able to taste PTC, and the recessive allele is represented as t. Assume that a population is in Hardy-Weinberg equilibrium and 16 individuals out of 100 are unable to taste PTC.
What are the allele
frequencies of T and t in this population?
A. The allele frequency of T is 0.80, and the allele frequency of t is 0.20
B. The allele frequency of T is 0.84, and the allele frequency of tis 0.16.
C. The allele frequency of T is 0.00, and the allele frequency of t is 0.40
D. The allele frequency of T is 0.50, and the allele frequency of t is 0.50.
Answers
Answer: a
Explanation:
A
The allele frequencies of T and t in this population are the allele frequency of T is 0.80, and the allele frequency of t is 0.20. Therefore, option A is correct.
What is allele frequency ?The relative frequency of an allele at a certain locus in a population, represented as a fraction or percentage, is known as gene frequency or allele frequency. The percentage of chromosomes in the population that carry that allele relative to the whole population or sample size is what is being discussed.
In human statistical genetics, the frequency of an allele in the population is a fundamental quantity. A lot of population and medical genetic studies are based on this amount. Allele frequencies are altered by numerous evolutionary factors. As a result, allele frequencies can be utilized to guess at previous evolutionary occurrences.
The distribution of genetic variation in a population is shown by the relative genotype frequencies. The fraction of all copies of a gene in a population that carry a certain allele is known as relative allele frequency.

Vincristine is a drug used to treat cancer. It prevents spindle fiber formation during mitosis. Which one of these events CANNOT occur due to
the usage of Vincristine?
-sister chromatid separation
-DNA replication
-chromosome coiling
-cytokinesis
Answers
Cytokinesis cannot occur due to the usage of Vincristine as it prevents spindle fiber formation during mitosis. The correct option is D.
Vincristine is a medication that prevents spindle fibres from forming properly during mitosis, which prevents the sister chromatids from being separated and being pulled to the opposing poles of the cell.
Sister chromatid separation cannot take place adequately in the absence of functioning spindle fibres, which prevents mitosis from progressing normally.
Vincristine, however, has no direct impact on chromosome structure or organisation, DNA replication, chromosome coiling, or any other cellular processes.
Vincristine use does not directly stop these processes, despite the fact that the disruption of mitosis may have an indirect impact on them.
Thus, the correct option is D.

Answers
Plutonic or intrusive igneous rocks form when it cools below the Earth's surface.
Igneous rocks form when it cools on the Earth's surface.
How is the rock formation process?They originate from the solidification of magma inside the Earth's crust or when lava comes out of the mantle, through a volcanic eruption. When magma cools slowly inside the crust, turning into rock, a process called intrusion occurs.
With this information, we can conclude that Igneous rock or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic and Intrusive, or plutonic, igneous rock forms when magma remains inside the Earth's crust where it cools and solidifies in chambers within pre-existing rock.

The star in the diagram
represents which of
these?
A. origin of replication
B. replication fork
C. replication bubble
D. Okazaki fragment
Answers
Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.

The scientific method primarily starts with a question about the subject matter that needs to be solved for which the research is performed and a hypothesis is given. After a hypothesis, is established experiments are conducted so as to make observations.
The observations are then analyzed to draw conclusions to present the findings. This interpretation gives the solution to the presented problems. The biologist was asking questions when he observed and compared the population of the frogs in the first and second years.
