The correct answer is 'inbreeding depression'. This is when more recessive<span> traits are manifesting in the phenotype. Recessive traits can only occur in offspring if both parents contain the recessive gene, and this is much more likely under reduced genetic diversity due to inbreeding. </span>Many alleles confer a selective advantage in the heterozygous and/or homozygous-dominant state, whereas the homozygous-recessive state confers less or even no advantage.
Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
2. detritivores are decomposes because they consume other material to break it down.
3. need to see the image on p.591 to answer but a producer is a type of plant that supplies energy to a first level consumer, a detritivore would be a type of fungi that is pictured because fungi break down materials.
4. the first box is mutualism. second box is commensalism. third box is parasitism.
<em>The function of skeletal muscles is to control the movement of internal organs. The skeletal muscle pulls the tendons attached to the bones.</em>
