As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Su
Ivahew [28]

Answer:

Explanation:

using the formula p² + 2pq + 2pr + q²+ 2qr + r² = 1 where p is IA allele is 0.35 and q is IB allele is 0.15.

Thus, the expected frequency of people with type AB blood in this population will be (2pq) = 2 x 0.35 x 0.15 = 0.105

b. The expected frequency of people with type A blood will be p² + 2pr = where r is found using the formular p + q + r = 1 = 1 - (p+q) = 1 - (0.35+0.15) = 0.5

Thus, we have the expected frequency of people with type A blood to be     (0.35² + 2x0.35x0.5) = 0.4725.

c.    <u> p² + 2pr</u> + <u>2pq </u>+ <u>q² + 2qr</u> +<u> r²</u>

       AA AO      AB      BB BO     OO

         1850       180        635      2335

frequency of IA- p = (1850 + 180/2) / 5000 = 0.388

frequency of IB- q = (635 + 180/2) / 5000 = 0.145

frequency of i- r = 2335/ 5000 = 0.467.

since r² = 2335, r = √2335 = 48.32

using the formula p + q + r = 1

DOMAINS AND KINGDOMS
iVinArrow [24]
For the first question, a unicellular eukaryote with autotrophic features (meaning it can produce its own food) will be from either Domain Bacteria and Domain Eukarya, but since Domain Bacteria is not in the choices, then Domain Eukarya is the answer. Domain Archaea are yes, unicellular organisms, but they are not eukaryotes and they do not possess autotrophic features. Domain Eukarya have photosynthetic protozoans (i.e. Diatoms).

For the second question, in Kingdom Fungi, you chose that fungi can either be unicellular or multicellular, which is true, for instance yeast and mushrooms respectively. Fungi are heterotrophic as they cannot produce their own food. The other answer is that fungi are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.

For the third question, in Kingdom Protista, you chose that protists can either be unicellular or multicellular, and this is true in the case of amoebas and kelp respectively. Protists can be both heterotrophic and autotrophic. The other answer is that protists are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.

Pepsi [2]

Answer:

Almost immediately after injection, you find yourself swept into a good-sized chamber, the left atrium. However, you do not stop in this chamber, but continue to plunge downward into a larger chamber below. You land with a large splash and examine your surroundings. All about you are huge white cords, hanging limply from two flaps of endothelial tissue far above you. You report that you are sitting in the left ventricle chamber of the heart, seeing the flaps of the mitral valve above you. The valve is open and its anchoring cords, the chordae tendineae, are lax. Since this valve is open, you conclude that the heart is in the systole/contraction phase of the cardiac cycle.

Explanation:

Once the oxygenated blood enters the heart through the pulmonary vein, it goes to the left atrium. From there, it goes down to the left ventricle passing through the mitral valve, also known as the bicuspid valve. This valve prevents blood's backflow when the heart contracts, allowing the blood's flow from the ventricle to the aorta.

The chordae tendineae, also known as tendinous cords, are in the mitral and the tricuspid valve. They are cords that are attached to the valve and the heart walls. They are lax during atrial systole, and with the help of blood pressure, they allow the valve to open and welcome the blood into the left ventricle. The tendinous cords are tense during ventricle systole preventing the valve from opening and causing a backflow from the ventricle to the atrium.

Answer:

Symptomatology and transmission

The clinical manifestations of acute HBV infection are age dependent. Infants, young children (younger than 10 years of age), and immunosuppressed adults with newly acquired HBV infection are usually asymptomatic. [2] Older children and adults are symptomatic in 30%–50% of infections
