In humans blood type is determined by the A B, and O alleles. The A and B alleles are codominant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes?
A. O only
B.A or B only
C A, B, or O only
D.A, B, AB, оr O
Answer:
d. A, B, AB, or O
Explanation:
The parent genotypes are AO and BO. Make a punnett square to see the genotypes of the offspring. I tried to make an example one below, but I suggest you draw one out for yourself.
A O
B AB BO
O AO OO
The four genotypes would be AB, BO, AO, and OO. Because A and B are dominant over the O allele, the phenotypes would just simply AB, B, A, and O.
When An individual with the AO genotype and an individual with the BO genotype can produce offspring so the phenotypes should be A, B, AB, or O.
What is Alleles?It is considered as the two or more genes that are available on the same locus of the chromosome.
Since
A and B are codominant genes.
O is a dominant gene, which can be masked by A and B alleles.
So here The genotype of the offspring can be A, B, AB, or O. It is because of the co-dominance of alleles.
Therefore, the option d is correct.

Crossing over is important because it ??? genetic diversity.
Answer:
Crossing over is important because it increases genetic diversity.
Explanation:
Crossing over is a process during meiosis that increases the genetic diversity in the offsprings. During this process, a pair of chromosomes interact with each other to swap genes. As a result, the sister chromatids are no longer identical, which causes offsprings to be different from their progenitors. Also, they give diversity to the species since the chromosomes are different.

Today where can continental glaciers be found in
Answer:
polar regions of Greenland and Antarctica
Explanation:
The glaciers of the Antarctic and Greenland ice sheets cannot be spoken of differently than mountain glaciers, as they form ice plateaus that rise high up to 4000 m (with individual peaks up to 5140 m) in Antarctica and 3700 m in Greenland, where the ice overlaps with plateaus and mountain ranges. Antarctic ice cover reaches a thickness of over 4300 m (average 1720 m), Greenland 3400 m (average 2300 m).

WHAT IS THE ANTICODON THAT WOULD PAIR UP WITH THE MRNA CODON UAG ?
Answer:
At one end, the tRNA has an anticodon of 3'-UAC-5', and it binds to a codon in an mRNA that has a sequence of 5'-AUG-3' through complementary base pairing. The other end of the tRNA carries the amino acid methionine (Met), which is the the amino acid specified by the mRNA codon AUG.

It is determined that Elsa is experiencing beta-thalassemia major. Which of the following statements is not true regarding this diagnosis?
A) The cause of beta-thalassemia is genetic.
B) Beta-thalassemia major is a grave condition and has a high mortality rate.
C) Beta-thalassemia major is often treated with blood transfusions.
D) Because beta-thalassemia is an x-linked trait, it affects males more often than females.
Answer:
The correct option is D
Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, it is not true that it involves just the x allele and thus affects males more often than females.
What is a dominant gene?
A gene that is identical in most of the world's population.
A gene that does not change from generation to generation.
A gene with a mutation that affects the surrounding genes.
A gene that is always expressed physically when present.
Answer:
1 or A
Explanation:
Don't trust me but that's what i think because dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive.

The first trophic level in every ecosystem is autotroph.
WHAT IS TROPHIC LEVEL:Trophic level is the position of an organism in the flow of energy within an ecosystem. In an ecosystem, energy flow begins with a set of organisms called producers or autotrophs. Examples of autotrophs are green plants, algae etc.Therefore, the first trophic level in every ecosystem is autotroph.

List four uses of lactic acid fermentation. List four uses of alcoholic fermentation.
Answer:
The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. Two of the most common applications of lactic acid fermentation are in the production of yogurt and sauerkraut.
Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.
Which of the following statements best describes why Lamarck's theory of evolution was incorrect AND why Darwin's theory of evolution was correct?
A. Lamarck believed that evolution happened very quickly BUT Darwin believed that evolution was a very slow process.
B. Lamarck believed that traits that you learn or develop over time could be passed on BUT Darwin believed you passed on traits you possessed at birth.
C. Lamarck believed that evolution had to be done artificially BUT Darwin believed it only happened naturally.
D. Lamarck believed you passed on traits you possessed at birth BUT Darwin believed that traits that you learn or develop over time could be passed on to your offspring.
Answer:
B.
Explanation:
Lamarck's theory basically says that traits that are developed over time can be passed on (Theory of Inheritance of Acquired Characteristics), which is incorrect. Darwin is correct that only traits possessed at birth can be passed on.
Lamarck believes that the traits which you learn or develop over time could be passed on. As per Darwin believed that you passed on the traits you possessed at birth. This the option B is correct.
What is the Lamarck theory of evolution ?The theory of Lamarck is based on the aspects of the evolution and is the principle that the physical changes in an organism during their lifetime as the development of the organs.
The use of the parts increases and can be transmitted to the offspring. The theory focuses on the use and disuse, an organism that is driven by greater complexity, effects of the environment, and needs.

Answer:
D. Lungs
Explanation:
Just from reading this question, I was able to gather that the answer would be Lungs because it is the one body part that would allow amphibians to survive on land. If they just had gills, they would not be able to survive on land because the gills would always require water. Most amphibians do not have fins, and they (particularly frogs) lose their tails after they grow to be adults. So, that is why my answer would be lungs.

Describe an adaptation of the bull kelp for gathering sunlight
Answer:
They have gas filled bulbs in order to stay at the top of the water
Explanation:
hope it helps
Bull kelp has evolved to capture sunlight because they have gas-filled bulbs that allow them to float at the surface of the ocean.
What are Bull kelps?Bull kelp is an annual seaweed, meaning it takes a year to develop from a spore to maturity. It can grow by as much as 10 inches (25.4 cm) in a single day. Bull kelp produces spores in reproductive patches (sori), which are mature enough to fall to the ocean floor.
Bull kelp was particularly useful for making lines for fishing nets, harpoons, and anchors. Dogfish oil, saltwater, and freshwater were used to cure the solid portion of the stipe (the stem portion) close to the bottom, sometimes for as long as a year. Because bull kelp can float at the ocean's surface thanks to gas-filled bulbs, they have developed to absorb sunlight.
Thus, Bull kelp has evolved to capture sunlight because they have gas-filled bulbs that allow them to float at the surface of the ocean.
