A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father
The sodium levels increase inside the cell during action potential. Opposite to resting state, depolarization is the shift of electrical charge resulting in positive charge inside the cell. Depolarization is the start of cell-to-cell communication and other necessary physiological functions of an organism.
Answer:
C) Bacteria congregated in these areas because these areas had the most oxygen being released.
Explanation:
Below is the full question:
Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.
What did Engelmann conclude about the congregation of bacteria in the red and blue areas?
A) Bacteria released excess carbon dioxide in these areas.
B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light.
C) Bacteria congregated in these areas because these areas had the most oxygen being released.
D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.
E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis.
The most efficient region of white light for photosynthesis has been found to be the blue and red region of the white light. Hence, these two regions must have had the most oxygen being released because they are the regions with the highest rates of photosynthesis.
<em>Aerobic bacteria thrived better in the regions illuminated by red and blue light because these regions had the highest oxygen production as a result of having the highest rates of photosynthesis.</em>
<em>The correct option is C.</em>
<h2>Cytokinesis in animal cells</h2>
Explanation:
- The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring:This statement is false because cytokinesis in animal cells starts with the assembly of contractile ring,contractile band consists of actin and myosin(microfilaments) which catalyse cleavage furrow formation
- As the contractile ring constricts, its thickness increases to keep a constant volume:This statement is false because thickness remains constant
- The midbody forms from bundles of actin and myosin: This statement is false because contractile ring forms bundles of actin and myosin whereas midbody is formed from microtubules
- Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring:This statement is false because local activation of Rho mediates profilin binding to actin and helps in assembly and contraction of contractile ring
The four letter string comes out to be FFFF
