Blood type in humans is an example of trait that has multiple alleles. The alleles for type A blood and type B blood are codominant, and type O blood is recessive to both type A and type B. If a girl with type AB blood has a brother with type O blood and a sister with type B blood, which of the following genotypes could it be possible for their parents to have?
AO and BO
AB and OO
AB and BO
AO and AB
Answers
The possible genotype is AO and BO.
An organism's genetic makeup is called its genotype, and it reflects all the alleles, or kinds of the gene, which are carried through the organism. Consequently, a test move can help determine whether a dominant phenotype is homozygous or heterozygous for a specific allele.
What are the 4 main blood groups?A person's blood type depends on the genes he inherited from his parents. ABO is the most well-known system for grouping blood groups, although there are other methods. There are four main groups in the ABO group: A, B, O, and AB. There are eight other blood groups in these groups.
More than 179 people in India are known to have Bombay blood type. If the organ donor belongs to the Bombay blood group, the donor liver must be free of A, B, and H antigens. In theory, the Bombay blood group donor can donate a liver to any blood group (universal donor).

Explain why the cane toad was a failure as a biological control method in Australia.
Answers
-The greyback beetle it was supposed to be eating fed at the top of the sugarcane stalks (which were 6-8 meters in height). Cane toads cannot fly or climb and therefore couldnt feed on the beetles.
-The beetles were out during the daytime, and cane toads feed at night.
-The two species are not seasonally compatible (aren't in the same place at the same time of year).
-The toads needed moist conditions to survive, and so moved away from where they were supposed to be.
-The cane toad eats many native species and often out-competes native species for food and breeding sites, leading to the decline of natives.
-Breeding habits made the cane toads a very invasive species.

What is most likely to result immediately after a rainforest in Brazil is clear cut
Answers
Answer:
The immediate effect of destruction of rainforest in Brazil is the global warming.
Explanation:
The brazil rainforest is present near the amazon basin and most of the amazon rain forest extends in Brazil. The Brazil rainforest as part of the Amazon rainforest provides oxygen to the earth. This acts as the lungs of the earth.
It is the home of many plant and animal species. It has two-thirds of the world's plant species. The world's 20 % oxygen comes from these forests.
If the forest will clear, then the amount of carbon dioxide gas increases. It leads to global warming and air pollution. Because carbon dioxide is a greenhouse gas and it increases the temperature of the earth. This is the immediate impact of the destruction of the brazil rainforest.
The forest is destroyed every day for various purposes such as excessive fishing, grazing of animals, and building of dams. Due to the destruction of the forest, many animals lose their habitat, which results in an ecological imbalance.

If cellulose is broken down through hydrolysis it will yields glucose.
The question discusses the biochemical processes of the conversion of glucose into starch, fructose and glucose into sucrose, and cellulose into glucose.
Explanation:The processes described involve the conversion of different types of sugar units. Firstly, the conversion of glucose units into starch occurs in plants as a means to store excess glucose produced during photosynthesis. This involves linking glucose molecules together to form a polysaccharide starch. Secondly, the conversion of fructose and glucose units to form sucrose is another common biochemical process. Sucrose is a disaccharide made by combining a glucose unit and a fructose unit. Lastly, the conversion of cellulose into glucose units represents the breakdown process where organisms, especially those living in the gut of animals, can convert cellulose back into glucose for their energy needs.

Explanation:Biology - High SchoolHans Selye called the body's response to stress the general adaptation syndrome (GAS). The GAS consists of three stages: the alarm stage, the resistance stage, and the exhaustion stage.
In the alarm stage, the body perceives a stressor and activates the fight-or-flight response. This leads to the release of stress hormones, increased heart rate, and heightened senses.
In the resistance stage, the body attempts to cope with the ongoing stress. It adapts to the stressor and tries to maintain physiological balance. However, the body remains on high alert and may experience symptoms of chronic stress.
In the exhaustion stage, prolonged exposure to stress overwhelms the body's resources. Physical and mental exhaustion may occur, increasing the risk of illness and disease.

In a diploid cell with 5 chromosome pairs (2n = 10), how many sister chromatids will be found in a nucleus at prophase of mitosis? Please explain why
Answers
Therefore, if there are 5 chromosomal pairs, there are 10 chromosomes. Each chromosome has two chromatids, which means that there are 20 chromatids.
The number of sister chromatids at the prophase of mitosis will be 20.
Further Explanation:
The cell cycle in eukaryotes comprises two stages: the mitotic phase and the interphase. The interphase is the growth phase during which the cell content grows and doubles with the accumulation of nutrients that are necessary for mitosis.
In the G1 phase of the interphase, the proteins and nutrients required for the S phase are synthesized. During this phase, the cell grows but does not undergo division. G1 phase is followed by the S phase during which replication of the DNA occurs and the cell's DNA content or the chromosome number doubles. The G2 phase is the cell's checkpoint to ensure that the DNA replication has been accomplished successfully with no damage. It also synthesizes protein machinery for the M phase for cell division to take place. In the M phase, the cell division occurs separating the DNA content equally into two daughter cells produced at the end of mitosis.
Here, the diploid cell has 5 pairs of the chromosome or the DNA content is 2n = 10. Each chromosome will have two chromatidsthat are joined at the centromere in the G1 phase.
After the S phase, the DNA content will double and each chromosome will comprise an identical sister chromatid pair. Therefore, there will be 20 sister chromatids after the completion of S phase or replication.
The M phase will start with the prophase containing 20 sister chromatids, two pairs from each chromosome. The sister chromatids will move towards the opposite pole and eventually divide into two daughter cells with an equal amount of DNA content (2n=10).
