00:02 Hello there.

00:03 I see that we have a list of options and we're going to go for each of them.

00:08 Okay, so when two organisms strive to obtain the same limited resources, what happens when it comes down to these type of situations? are they members of the same community? are there members of the same species? they are said to be in competition with each other.

00:31 Or they are saying they are members of different communities if you said these are members of different communities you are correct because in theory these are like intra species competition because they can't occupy the same area in the same space at the same time so that's the reason why the next one if a country were to experience a severe epidemic of aids which the following would be least likely to change.

01:06 Birth rate, death rate, density, or carrying capacity.

01:11 If you said death rates, you are correct.

01:16 Sorry, i hit my hand.

01:18 The next one.

01:19 Which of the following are major density -dependent, limiting factors in population? select all that applies.

01:28 So if you selected parasitism.

01:34 Intraspecies competition or intraspecific competition or predation.

01:40 And predation, you are correct because the weather conditions are density and dependent limiting factors, not dependent.

01:51 Okay.

01:53 The next one.

01:54 Which measurement is not part of a life table? age of organism reaches puberty, number dying.

02:04 In age, interval, mortality rate per hundred, per thousand a life for life expectancy.

02:14 If you said age, that organisms reaches puberty, you are correct because for the life table, they're just basically calculating, you know, the intervals like the likelihood of certain organisms that are able to live or to survive up to a certain age.

02:39 Okay, the next one.

02:42 When a predator and prey population are mixed in very simple lab experiments, what happens? the predator will increase as the prey population decrease...
