Suppose that of a cohort of 200 rats in a rat colony born in January, 160 are still alive at the start of March and 120 are still alive at the start of May. What is the survivorship up to the start of March
Survivorship is the probability that individuals from the original cohort (age 0) get to a certain age (age x). Survivorship up to the start of March is 0.8.
What is a life table?
It is a representation of life and death patterns in a cohort. It includes the probability for different organisms in the population to live, survive, reproduce or die.
It is composed of information provided by parameters like age structure, natality rate, and death rate per age concerning the whole population.
There are two types of life tables:
Horizontal life tableVertical life tableWhat is the horizontal life table?This is a representation of a cohort destiny, from the born moment to the death moment of all individuals, including survival and fecundity per age.
A cohort is a group of individuals of the same age that are incorporated into the population at the same time.
This table is based on different vital statistics. Among them, we can mention,
Number of individuals registered at a certain age, N(x)Number of individuals at initial age (recent born, seeds, propagule), N(0)Specific survivorship per age, l(x)Transition rate from one age to the next one, p(x)The proportion of the original cohort that dies during a certain age x, d(x)Specific mortality per age, q(x)
Specific survivorship per age, l(x), is the proportion of individuals from the original cohort that gets to survive reaching a certain age. It is the probability that a recent born gets to a certain age.
l(x) = N(x) / N(0)
Values must go from 0 to 1. By definition, when l(x) = 1, then X = 0
In the exposed example, we know that
N(0) = 200 rats ⇒ new bornsN(x) = 160 rats ⇒ three months individualsl(x) = N(x) / N(0)
l(x) = 160 / 200 = 0.8
Survivorship specific per age up to the start of March is 0.8 = 80%

C. releases into the atmosphere in their everyday life
D. creates in their everyday life
Answer:
c
Explanation:
A carbon footprint is an estimate of how much carbon a person releases into the atmosphere in their everyday life. Therefore, option C is correct.
What is carbon footprint ?A carbon footprint is the entire amount of greenhouse gas emissions—expressed as carbon dioxide equivalent—that a person, event, organization, service, place, or product is responsible for.
The overall amount of greenhouse gases released during the manufacture, manufacturing, and selling of consumer goods is estimated by carbon footprints. The goal is to identify the main supply chain emissions sources and educate the appropriate stakeholders so that emission-reduction measures can be performed.
It consists of gases including fluorinated gases, methane, nitrous oxide, and carbon dioxide, which trap heat in the atmosphere and contribute to global warming. Carbon dioxide is the gas that humans emit most frequently. The main sources of a person's carbon footprint are often their transportation, housing, and food.
