The answer would be hypotonic
A. for cooking food and transmitters
Answer:
D. unnatural scream
Explanation:
The Bigfoot is a an animal around there's lot of debate, as there are thousands of sightings, but not conclusive proof that it actually exists, thus it falls into the category of mythological creatures for the time being. This creature has been described by thousands of people that claim to have seen it or hear it, and the descriptions are pretty much the same, very tall, hominid-like, bipedal, dark fur, very quick, and terrifying. Something else that is a specific feature of the creature is the sounds its make, as everyone has said that it produces incredibly powerful unnatural sounding scream. People have said that they have frozen from fear after hearing those sounds, and that whenever that sound occurs all other animals run away frightened in the opposite direction.
Genotype is 1:2:1 (1 Homozygous tall, 2 heterozygous tall, 1 homozygous short)
Phenotype ratio is 3:1
The heterozygous Tt and recessive tt could produce short pea plants if they were crossed.
Explanation:
Genotype is the alleles present for a particular gene. In the Punnett square we can see there will be three tall pea plants and one short pea plant but they can be either homozygous or heterozygous.
While phenotype is the exhibited trait by particular allele that is 3 tall pea plants and one small pea plant.
If Tt and tt are crossed 50 per cent chances of short pea plant is there.
Answer:
E. All of the above
Explanation:
In cardiac contractile cells there is rapid depolarization, then a plateau phase and repolarization.
when an action potential stimulates the cell, voltage-gated channels open quickly commencing the positive-feedback mechanism of depolarization. This in turn raises the membrane potential to approximately +30 mV, and this closes the sodium channels. Next comes the plateau phase, where membrane potential declines relatively slowly due to the opening of the slow Ca2+ channels, allowing Ca2+ to enter the cell while few K+ channels are open, leading to K+ to exit. Once the membrane potential reaches approximately zero, the Ca2+ channels close and K+ channels open, allowing the exit of K+. The repolarization lasts approximately for a while and here is when the membrane potential drops until it reaches resting levels once more and repeats the cycle.
