Answer:
Гліколіпід
Пояснення:
Рослини, земноводні та комахи не гинуть, коли температура їх тіла опускається нижче 0 ° C, оскільки їх організм виділяє такий матеріал, як гліколіпід (AFGL), який використовується як захист від замерзання в організмах. Гліколіпід - антифризна речовина, яка запобігає зв’язкам молекул води, і ця хімічна речовина зв’язується з молекулами води, щоб уникнути замерзання всередині клітини.
Answer:
False
Explanation:
Humans do compete over food, but they also compete over habitat and other things that I can not think of right now but just know your answer is false.
Answer:
(A) The variation resulting from meiosis and the union of gametes means some individuals will have a chance of colonizing diverse distant environments successfully.
(D) Vegetative propagation is more efficient than sexual reproduction when the current generation is well adapted to the local environment.
Explanation:
Sexual or asexual (options B and C) are not a "last ditch", it pretty much depends on the type of organism and its strategy for survival. There are thousands of organisms that can reproduce either sexually or asexually depending on the environmental conditions.
Option A. Genetic variability is important because sometimes the genetic variability produce during the sexual reproduction processes (crossing over, chromosomes assortment and DNA from 2 parents) can confer an organism the adaptability mechanism to thrive in different environments.
Option D. Since asexual reproduction delivers genetical equal organisms, the offspring is already adapted to local conditions and can colonize at a faster rate.
Answer:
The correct answer is paired sample t-test.
Explanation:
Based on the given information, the mothers living in poverty in the United States give birth to underweight babies. The average weight of the babies given birth by women living in poverty is 2.8 kg. To examine the efficacy of a novel prenatal care program, a test was conducted by the CDC in which 30 mothers living in poverty and the weights of their babies were recorded.
As the test is conducted in pairs, thus, paired sample t-test would be the appropriate hypothesis test. The paired t-test is performed when the dependent variable is measure spontaneously. In the given case, the women participating in the program and the number of babies with less birth weight are examined in pairs. Thus, as the sample are paired together, the correct answer would be paired sample t-test.
Photosynthesis removes the carbon dioxide and releases the oxygen, but cellular respiration is the opposite because it uses the oxygen in order to release the CO2. So the carbon atoms are released during cellular respiration.
