Vesnalui [34]

Answer:

The correct answer is BB genotype and BO genotype.

Explanation:

The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).

If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.

Thus, the correct answer is the BB genotype and BO genotype.

What is normally present in urine? How does the filtration barrier function to prevent things from entering the filtrate? What d
Sergio039 [100]

Answer:

Generally urine comprises about 95 percent water, 2 percent electrolytes, that is, ions of salts, primarily sulphates, chlorides, potassium, bicarbonates of sodium, and others, 2.6 percent urea, 0.3 percent uric acid, and small quantities of ammonia, creatinine, hormones, some of the pigments, hippuric acid, and allantoin.  

The filtration barrier comprises of the glomerular capillaries fenestrated endothelium, the filtration slits of the podocytes, and the fused basal lamina of the podocytes and the endothelial cells. The barrier allows the entry of water, small molecules, and ions from the bloodstream into the space of Bowman capsule.  

The barrier restricts passing of negatively charged and/or large proteins like albumin. The basal lamina of the filtration barrier comprises three layers. Any small molecules like glucose, water, salt, urea, and amino acids can pass freely into the Bowman's space, however, the cells, large proteins, and platelets do not.

Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.
