Drupady [299]

Answer:

Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.

The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.

According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.

Arrange these elements of the intrinsic conduction system in the order that a depolarizing impulse travels during a normal heart
zlopas [31]

Answer:

SA Node

Inter-nodal Pathways

AV Node

AV Bundle

Bundle Branches

Purkinje Fibers

The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.

When you are cold, your muscles begin to contract involuntarily and cause you to shiver. why do you think this occurs? how does
DanielleElmas [232]
Shivering occurs when the core temperature of the body begins to decrease which would threaten normal body function. Shivering is a response by the body to bring back temperature back to homeostasis. Trembling is the continual involuntary contraction of muscles. Muscle activity releases heat that warms up the body. This is the reason why we sweat during physical activities as the body sheds excess heat generated by the muscles in order to maintain the homeostatic body temperatures of 37 degrees centigrade.

How many years might primary succession take with medium amounts of rainfall and temperature? Explain why ​ HELPP PLEASE HELP
serious [3.7K]

Answer:

The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.

Explanation:

The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.
