Answer:
D. Mutually beneficial: the bee receives pollen and the flower gets help with its reproduction
Explanation:
It is a mutually beneficial relationship because the flower provides the bee with nectar and pollen. Also, the bee provides the flower with a means to reproduce by spreading pollen from flower to flower through pollination.
Answer: Sugar metabolism
, DNA replication and lipid synthesis.
Explanation:
The pathways or the phenomenon is very fundamental that takes place in all the living organisms.
These processes are fundamental to life and is vital for the growth and development of the organism. The cell proliferation and growth is also very essential in case of bacteria.
hence, these processes are highly conserved from one species to another species.
Answer: The genotype of the pea plant is Tt. T is the dorminant allele and t is recessive.
Tall is the phenotype.
Explanation:
Genotype is a genes of an individual which show the phenotype or the traits.
From the above question, the pea plant have genes of T tall and t for dwarf,because T is dorminant , it is expressed over recessive.
The genotype of the pea plant is Tt.
Phenotype is the observable or visible characteristics the organism posses which is as a result of the genotype been expressed.
The phenotype is Tall.
That question is confusing. Cells obviously take from its parent cells, which means that DNA is combined from both mom and dad in a unique way. That can cause the offspring to have either the mom's or dad's eyecolor. So the "different genes" part apply to that because for each feature of the offspring it is a complex combination of mom and dad. What I don't get is the different cells. there are these things called stem cells which are basically cells that can be anything in the body when there's a need for it. A stem cell can be a nerve cell or muscle cell for example. So i don't think it requires genes to be exact to form a cell. I hope you get what I'm trying to say
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.
