If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?
A The climate would get colder and drier as you go up the mountain.
B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.
The climate would get colder and drier as we go up the mountain. So, the correct option is A.
What is the effect of altitude on the atmosphere?When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.
Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.
Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.

Answer:

Explanation:
Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.
a. True
b. False
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.

which RNA molecule carries amino acids
Answer:

6. In a population of angiosperms in Hardy-Weinberg equilibrium, the allele, C, conferring red flowers is completely dominant to the allele, c, causing white flowers. If allele C is at frequency 0.7 in the population, what is the expected frequency of red flowered plants
Answer:
The correct answer is - 0.91.
Explanation:
Given that C is dominant over c with an allelic frequency of 0.7. The sum of the frequency of dominant alleles and the frequency of heterozygous alleles in this H-W population of angiosperm will be the expected frequency of red-flowered plants.
The frequency of C = 0.7
(p² = dominant allele frequency)
Then, the frequency of dominant genotype CC would be = 0.7×0.7 (p² = dominant allele frequency)
As we know that P + q = 1
then q = 1 - p
q (frequency of recessive allele) - 1 - 0.7
q = 0.3
Then frequency of heterozygous genotype Cc= 2pq
= 2×0.7×0.3
= 0.42
The frequency of red flowers = freq of CC + freq of Cc
= 0.49 + 0.42
= 0.91
Given that C is dominant over c with the frequency of 0.7
The sum of the frequency of dominant allele and heterozygous alleles in this H-W population of angiosperms expected frequency of red-flowered plants.
frequency of C = 0.7
[tex]p^{2} =dominant allele[/tex]
CC= 0.7 × 0.7
[tex]p+q =1\\q= 1- p\\= -1-0.7\\=0.3\\[/tex]
Then frequency of genoype = Cc= 2pq
= 2×0.7×0.3
= 0.42
[tex]frequency of red flower = freq of CC + freq of Cc[/tex]
= 0.49 + 0.42
= 0.91.
What is Hardy-Weinberg equilibrium?It is a principle that states genetic variation in a population will remain constant from one generation to the next generation in the absence of disturbing factors.
Hence concluded that the frequency of red-flowered plants = 0.91

A. They have a common ancestar
B. They are comparable in size as adults
C. They evolved at the same time
D. They move in the same way
The similarity of the bone structure suggest about these animals should be that they evolved at the same time
What is bone structure?Bones are considered to be the living tissue that comprise of the own blood vessels, and should be made of the various cell, proteins, minerals, etc. In this it enables them for growing, transformation, and repair via the life.
Since both arm and legs should have one bone at the top, so here we considered the option c should be right.

1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.

a. DNA
b. mRNA

Answer:
reverse transcriptase
Explanation:
The following is NOT a nucleic acid is - d. protein as it is a different macronutrient or macromolecule to nucleic acid.
Nucleic acids are macromolecules of a special class found in all living organisms and also in viruses. There are two types of major nucleic acids, DNA or deoxyribose nucleic acid and RNA or ribose nucleic acid.
Nucleic acids play a role in genetic materialnucleic acid helps in protein synthesisRNA is mainly three types mRNA, messenger RNA, tRNA transfer RNA, and rRNA ribosomal RNA.DNA is normally double-strandedProtein on other hand is a different class of macromolecules that perform many roles in the cell such as, structure, function, and regulation.
