Concept of Terrestrial ecosystems
A terrestrial ecosystem is a community of organisms and their environment that occurs only on land masses, such as continents or islands.
In addition, there are six primary terrestrial ecosystems that are:
TundraTaiga.Deciduous temperate forest.Rain forest.Temperate grasslands and shrublandsshrublandsdesert.
Terrestrial ecosystems are distinguished by their low water availability and the consequent importance of water as a limiting factor, as opposed to aquatic ecosystems. Terrestrial ecosystems are characterized by wider temperature fluctuations, both daily and seasonal, compared to aquatic ecosystems of similar climates.

which channel type triggers the rapid depolarization phase of the autorhythmic cell action potential?
The fast sodium channel triggers the rapid depolarization phase of the autorhythmic cell action potential.
Rapid sodium influx causes depolarization and reversal of the membrane potential inside the cell from negative to positive. Depolarization is an all-or-nothing event in neurons that is initiated by the opening of sodium ion channels within the plasma membrane. Repolarization, the subsequent return to resting potential, is mediated by the opening of potassium ion channels.
Autorhythmic cells lack a resting membrane potential, which drifts and changes as a result of ionic movement. Hyperpolarisation causes voltage-gated sodium channels known as funny channels to open, allowing [tex]Na^{+}[/tex]Na+ into the cell.

if heterozygous round crossed with homozygous round produce 2400 plant how many plant are pure round
If heterozygous round plant is crossed with a homozygous round plant, then it will produce 2400 plant from which 1200 plants were pure round i.e., homozygous (RR).
What is Inheritance?Inheritance is the transfer of characters from the parent generation to the offspring. It takes place through the DNA which contains chromosomes and genes. The genes are responsible for the development of various characteristics in the daughter generation.
According to Mendel's genetics, for each character or gene a pair of contrasting alleles which code for different phenotype is present.
Here, a heterozygous round plant (with two different alleles) is crossed with a homozygous round plant, which results into the production of 2400 plants in the F1 generation.
Therefore, the total number of plants which are pure round can be calculated by Punnett square.
Pure round plants are the plants which are homozygous (RR) and pure wrinkled plants are (rr).
Therefore, the number of plants which are pure red = 1/2 of the total plants or 50% of the total plants.
Thus, number of pure round plants = 1/2 × 2400
Number of pure round plants = 1200

what would happen to a mammalian heart if the nerves leading to it were severed? the heart muscle would stop contracting. only the atria would be able to contract. the heart muscle would contract randomly. systolic contraction would still occur, but diastolic relaxation could not occur. the heart muscle would continue to contract but its contraction rate may change.
If the nerve endings of a mammalian heart were severed, the muscles of the heart would not stop contracting, but their rate of concentration changes.
How are nerves supplied to the heart?
The heart’s nervous supply is autonomic. It has parasympathetic and sympathetic parts both.
Sympathetic system: It acts on the sinoatrial node, dashing up the change rate, and thereby the heart rate increases.
Parasympathetic system: It works in reverse, which slows down the heart rate. The heart contains a natural pacemaker (sinoatrial node) which is why a nervous supply is not required. If the nerves to the heart are severed, then it'll still beat. As a matter of fact, it will beat quicker than normal, since there's commonly a parasympathetic supply that is slowing the heart down.

living organisms increase in complexity as they grow and this results in a decrease in the entropy of an organism. how does this contradict the second law of thermodynamics? explain how living organisms still obey the second law of thermodynamics despite their constant increase in order
Living organisms do not obey the second law of thermodynamics which states that an organism's entropy increases with each conversion of energy.
Organisms maintain order when the environment changes, and they become less ordered according to the second law of thermodynamics. These events actually work in concert when living organisms create ordered biological structures by increasing local entropy. Living organisms can gain or lose energy from the external environment.
Therefore, organisms are open systems. Since organisms are not closed systems, this does not affect the second law of thermodynamics. According to the second law of thermodynamics, all processes must cause a net increase in the entropy of the universe. It is true that entropy decreases and order increases as an organism grows.
