comparative profile for covid-19 cases from china and north america: clinical symptoms, comorbidities and disease biomarkers
Hatshy [7]

Different people are affected by COVID-19 in various ways. The symptoms experienced by infected individuals have ranged widely, from little discomfort to serious sickness.

  • The susceptibility to and prognosis of severe acute respiratory syndrome caused by coronavirus 2 or coronavirus disease 2019 (COVID-19) have been found to vary greatly amongst individuals and populations.
  • Intervention in public health must take into account these variations and how they affect susceptibility to infection and the severity of disease.
  • The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors.
  • These inter-population variances, together with intra-population variability, highlight the need to identify how health inequities and inequalities affect the public health response to COVID-19 and can help with preparing for the epidemic's resurgence.

Stells [14]

Answer:

The common garter snake (Thamnophis sirtalis) is found throughout North America. In the South, it is active year round. In the North, it is active during the warmer months but hibernates during the winter. It is commonly found basking on warm rocks during cool mornings. This lifestyle indicates that the snake is probably <u>heterothermic</u>.

Explanation:

Being heterothermic, like all reptiles, garter snakes bask in the sun to regulate their body temperature. During brumation (the reptile equivalent of hibernation), garter snakes typically commonly den together. Sometimes there will be as many as 100 snakes in one cave. A large, communal or group site is called a hibernaculum they occupy is called hibernacula. These snakes will migrate large distances to brumate.

Snakes do not actually hibernate, rather they become less active during cold weather. It is called "brumation."  Brumation is an extreme slowing down of their metabolism. Snakes are awake, but just very lethargic so you don't see them moving around.

During fall, snakes go back to the previous year’s den. When a sudden cold catches them before they get there, they may die if not fortunate enough to  find a suitable secondary den. They usually do not stay long at the den entrance, but hurry in for the long winter sleep.

Cold-blooded animals like snakes, fish, frogs, and turtles need to spend the winter inactive, or dormant,  because they have no way to keep warm. Snakes will crawl into any area free from frost such as caves, hollow logs, holes under trees and stumps, under wood piles, in other animal's burrows, and occasionally in a person's basement.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96

What impact does the atmosphere have on the Earth’s cycles? Check all that apply. produces wind currents
bazaltina [42]

Answer

The Impact that the Atmosphere has on the Earth’s cycle is it moves oxygen and carbon dioxide through the biosphere and transfers water into Earth’s oceans.

Explanations

The two main activities which affects the Earth’s cycle are the carbon cycle and water cycle. The increase in greenhouse gases in the Atmosphere has resulted into the greenhouse effect especially the amount of temperatures experienced on the surface of earth. An increased temperature has caused changes to the environment and ecologies.
