if a man with type BO blood has a child with a woman that has type AB blood, what is the percent probability that their child will have type AB blood?
The percentage for the child to have AB blood is 25%. Since BOxAB=BA,BB,AO, and OB, then each of them all of 25% to be the child’s blood type. 100% divide 4=25%.
If a man with type BO blood has a child with a woman that has type AB blood, then the percent probability of the child with blood type AB will be 25%.
What is Blood typing?A blood type is a classification of blood, which is based on the presence and absence of the antibodies and inherited antigenic substances on the surface of the red blood cells (RBCs). These antigens may be proteins, carbohydrates, or glycolipids, depending on the blood group system.
If a man with type BO blood has a child with a woman that has type AB blood, then the percent probability that their child will have type AB blood are as follows:
Probability of blood type AB = 1/4 or 25%
The probability of the child to have blood type AB will be 25%.

A. What is the function of the genes in DNA molecule?
B. How is DNA compacted to form a chromosome?
C. How is the cell divided during mitosis?
a. Genes are a section of DNA that are in charge of different functions like making proteins. Long strands of DNA with lots of genes make up chromosomes. DNA molecules are found in chromosomes. Chromosomes are located inside of the nucleus of cells.
b. DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes.
c. Mitosis is the phase of the cell cycle where chromosomes in the nucleus are evenly divided between two cells. When the cell division process is complete, two daughter cells with identical genetic material are produced.
A. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.
B. To package DNA inside the nucleus, cells wrap their DNA strands around scaffolding proteins to form a coiled condensed structure called chromatin. Chromatin is further folded into higher orders of structure that form the characteristic shape of chromosomes.
C. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. ... Meiosis also allows genetic variation through a process of DNA shuffling while the cells are dividing.

Using indoor tanning bed before the age of 35 can increase your risk of melanoma, the deadliest form of skin cancer, by 59 percent. The risk increases with each use. Research demonstrates that even people who do not burn after indoor tanning or sun exposure are at an increased risk of melanoma if they tan indoors; therefore, exposure to the radiation emitted by tanning beds can cause skin cancer. This cancer is the direct result of a:
a) mutation in a protein
b) mutation in the genetic material
c) change in fat molecule
d) change in a starch molecule
Answer: mutation in the genetic material
Explanation: just took the test and got it right
This cancer is the direct result of a mutation in the genetic material.
What is Mutation?Genetic mutations, which occur as your cells divide and generate duplicates of themselves, are modifications to your DNA sequence. Your DNA teaches your body how to develop and work.
Genetic changes may result in diseases like cancer or, in the long run, may enable people to adapt to their environment more successfully.
A change in the DNA sequence is referred to as a genetic mutation. Your cells receive the information they require to carry out their functions from your DNA sequence.
Therefore, This cancer is the direct result of a mutation in the genetic material.

As the atmosphere and Earth's surface materials absorb ultraviolet light, visible light, and infrared energy, they gain thermal energy and their temperatures rise. Which of the following best explains why the dry and sandy areas of deserts are hotter than the water in oases, even when the areas are both at the same latitude and altitude?
A. Water's ability to moderate temperature is less than that of sand.
B. Water's ability to morerate temperature is greater than that of sand.
C. Water is a polar molecule that reflects heat energy with like eletrical charges.
D. Water is a polar molecule that attracts hear energy with opposite electrical charges.
The dry and sandy areas of deserts are hotter than the water in oases, because of the water's ability to moderate temperature is greater than that of sand. Thus, the correct option is B.
How does water moderate temperature?Water has a high specific heat capacity which makes it absorb a lot of heat energy before it actually begins to get hot or raise the temperature of the water body. The specific heat of water has a huge role to play in the Earth's climatic conditions and it also helps to determine the habitability of many of the geographical locations around the globe.
The dry and sandy areas of deserts are hotter than the water in oases, even when the areas are both at the same level of latitude and altitude because of the water's ability to moderate the temperature than that of sand.

Which two terms are most closely related to learned behavior?
Complete question:
Which two terms are most closely related to learned behavior?
insight and trial-and-error reflex and insight instinct and trial-and-error imprinting and reflexAnswer:
insight and trial-and-errorExplanation:
Learned behavior: The learned behavior is the one that the organism develops as a result of experience. Learned behavior contrasts with innate behavior, genetically programed that are performed with no previous experience. This behavior is not inherited from parents to progeny; instead, it is developed during life as a result of experience and environmental influence. Learned behavior allows the individual organism to adapt to changes in the environment, and they modify by the different experiences. Insight learning: Learning that the individual gains when faces a problem for the first time and behaves to resolve it. Trial-and-error learning: Learning that the individual gains when facing a situation and trying to solve it in different alternative ways that might fail, until one of them is the correct one.When the animal or the organism faces a problem or a situation for the first time, with no previous knowledge or innate knowledge of how to solve it, it must deal with the situation in different ways until finding the solution or the correct way to get over it. Once the animal gets over the situation, it learns how to behave the next time.
Investigation of HOX genes indicates that the animal family tree" can be simplified to only how many different types of animals?
Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.

As a cell grows it’s Increase more than it’s.
Answer:
volume
surface area
Explanation:
The growth of the cell includes the increase in the mass of the cell by the absorption of nutrients and elimination of the wastes. This process helps the cell to grow in size. In this process, the volume of the cell increases faster than the surface area. This gradually leads to the decrease in the surface area of the cell. The increase in the volume expands the cell membrane also.
