Temperature decreases at high altitude​

Biology
1 answer:
spin [16.1K]2 years ago
5 0

Answer:

Higher the altitude, the thinner the atmosphere gets. The total heat content of a system is directly related to the amount of matter present, so it is cooler at higher elevations.

Here cooler means decrease in temperature.

Which correctly describes crossing over?
ollegr [7]

The correct option is A ie the process whereby non-sister chromatids exchange genetic material

  • Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
  • When genetic material is switched between two chromosomes, this process is known as crossing over.
  • It is in charge of causing genetic variation among members of a species.
  • Only the reproductive cells known as gametes undergo this process.
  • The steps involved in crossing over are as follows:

1) Synapsis.

2) Chromosome duplication

3) Crossing over.

4) Terminalizataion.

Which value is being measured in the columns labeled fraction remaining and percentage remaining
ahrayia [7]

<u>Question</u>:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

  1. years of decay
  2. quantity of energy
  3. number of stable atoms
  4. amount of material that has not decayed

<u>Answer</u>:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

<u>Explanation</u>:

The table shown below having explains about the half life , the  amount of sample in both fraction and percentage. The first column named half life elapsed tells  us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind  after the half life particular number of half life has completed.  similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over \frac{1}{16} th of the sample remained. In percentage it is 6.25%

Why is the caloric value of some sugar alcohols less than 4 kcal/g? a. They cannot be transported into the mitochondria. b. None
avanturin [10]

Answer:

Option-C

Explanation:

The sugar alcohols are the carbohydrates which are neither considered sugars nor alcohols but they partially resemble the structure of both of these sugars and alcohol.

The sugar alcohols are naturally present in the vegetables and fruits but they are also artificially synthesised like xylitol, lactitol, mannitol and others.

They are considered the alternative from of sugar but they provide less energy as compared to carbohydrates like they provide about 0-3 kcal per gram whereas sugar provides 4 kcal per gram.

This difference is due to the reason that they are not completely absorbed by the human body and also they are incompletely metabolized therefore provide less energy.

Thus, Option-C is the correct answer.

In poultry, black is dominant to white, but the heterozygote is blue. If you consistently
balu736 [363]

Answer:

indeterminate

Explanation:

The answer would be <u>an indeterminate number of generations.</u>

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

<em>Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.</em>
