Answer:
codominance
Explanation:
The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.
what is antigen?The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles in a heterozygous individual are fully expressed in the phenotype. Therefore, in the case of blood type AB, the A and B alleles are codominant, and both antigens are expressed on the surface of the red blood cells.
Hence, The mechanism that explains how both A and B antigens produce type AB blood is codominance. In codominance, both alleles are expressed equally in the phenotype, which means that both the A and B antigens are present on the surface of the red blood cells in type AB blood.

In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BBFF x bbff cross would be expected to be heterozygous for both traits?
Answer:
100%
Explanation:
This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).
In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:
BBFF - BF, BF, BF, and BF
bbff - bf, bf, bf, bf
Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

In the United States, most racial discrimination comes in the form of ________ discrimination.
A. Direct
B. overt
C. indirect
D. extra
Answer:
C, indirect because most people do not admit that they are racist and claim that they didn't do things because they're racist.
Explanation:
In the United States, most racial discrimination comes in the form of indirect discrimination. Therefore, option C is the correct option.
What is indirect discrimination?Indirect discrimination involves the policies or practices that appear neutral on the surface, but deep down have adverse effects on the people belonging to a particular race.
Indirect discrimination can be seen in various areas, such as employment. During a job vacancy, the job applicant requires to speak a high level of proficient English which appears to be a reasonable requirement for the job, but it can lead to a significant impact on non-native English speakers.
Indirect discrimination can be seen in the education field where schools give admissions to only those students who will qualify for a specific education test which may seem unfair to students belonging to a specific race, and having different educational backgrounds.
Therefore, indirect discrimination is the most common form of discrimination observed in the United States.

Answer:
What are 6 things the ocean provides for humans?
The Ocean produces more oxygen than the Amazones.
The Ocean regulates the Earth climate.
It is an important source of food.
The best holidays are close to the water.
Many jobs are related to sea activities.
The Ocean has therapeutic properties.
Explanation:
It is often thought that rainforests are the primary source of oxygen on the planet, but the truth is that rainforests are only responsible for 28% of the oxygen on earth while oceans are responsible for the 70%. It does not matter how far we live from the sea, from every ten breaths you take seven come from the ocean
In many ways, the sea regulates our climate. It soaks up the heat and transports warm water from the equator to the poles, and cold water from the poles to the tropics.
The ocean is the number one source of protein for more than a billion people. Fish accounts for about 15.7% of the animal protein consumed globally (2). Although, not everything is fish and seafood.
The ocean is not just home to us ocean lovers, but it is home to the greatest abundance of life on our planet. When you sail across an ocean, you will see dolphins, whales or a turtle popping up to take a breath.
The ocean is a happy-zone! Our temple, our life, our second home, our exhilaration place. It’s where we swim, surf, sail, dive, chillax, and ‘lime’. Family holidays and Sundays often happen on the beach. For sailors, fisherman and islanders, it also is a transport zone.
The FAO estimates (6) on the most recent official statistics indicate that 59.6 million people in the world were engaged in fisheries and aquaculture in 2016. Only at the European Union level, the blue sector represents 3.362.510 of jobs(7), in 9 subsectors: coastal and maritime tourism, Aquaculture, Renewable Energy, Mineral Resources, Biotechnology, Fisheries, Shipbuilding and Ship repair, Offshore Oil and Gas, and Transport.

Thomson's model of the atom needed to
change.
Answer:
Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup." Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom.
When does
transcription
happen?
Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...

Paragraph about Cellular respiration
Answer:
where's the paragraph?
Explanation:
The result of photosynthesis as glucose and oxygen
A reactants
B products
C gas exchange
D chlorophyll
The result of photosynthesis as glucose and oxygen is basically products. The correct option is B.
What is photosynthesis?Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Photosynthesis is important because it is the process by which plants convert carbon dioxide into oxygen using sunlight.
Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.
Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis.
Water is metabolized within the plant tissues, which means it ends up losing electrons, whereas carbon dioxide is reduced, which means it gains electrons. This converts water to oxygen and carbon dioxide to glucose.
Thus, the correct option is B.

Answer: This is because sharks are pregnant for 6 months to 2 years. Which decreases shark population due to slow birth rates. This also effects female sharks health die to the stress of carrying many sharks for up to 2 years. Most sharks die before or after giving birth. Overfishing for sharks is rapidly decreasing the shark population due to slow breeding but many fisherman. Less females and males are able to mate and sharks are pregnant for so long that the female has a high percentage of getting caught. In the long run more and more sharks are being killed each year which decreases sharks population for obvious and non obvious reasons.

What does gyrase do during DNA replication?
Explanation:
DNA gyrase is an VERY important bacterial enzyme that catalyzes the ATP-dependent negative super-coiling of double-stranded closed-circular DNA. Gyrase categorized to a class of enzymes known as topoisomerases that are involved in the control of topological transitions of DNA. The mechanism by which gyrase is able to influence the topological state of DNA molecules is of inherent interest from an enzymological standpoint. Much attention has been focused on DNA gyrase as the intracellular target of a number of antibacterial agents as a paradigm for other DNA topoisomerases. Current knowledge concerning DNA gyrase by addressing a wide range of aspects of the study of this enzyme. I hope this makes sense to you!
