<span>The biome is characterized by climate, temperature, and rainfall. The climatic factors that intervene are the altitude, latitude, and types of soil. Latitude determines temperature and seasonality and defines polar, subpolar, temperate, subtropical and tropical climates. Precipitation and latitude determine wet, sub-humid, dry or seasonal, semi-arid and arid types. The altitude determines the basal, premontane, montane, alpine and snow types. And only soil types are a determining factor in the influence of climatic factors and their variation and behavior within the biome.</span>
Answer:
The natural selection on polygenic traits affects selection.
Explanation:
The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.
This occurs in three ways that are disruptive selection, stabilizing and directional selection.
Answer:
See the answer below
Explanation:
The central dogma gives a description of how genetic information travels in biological cells from DNAs to proteins. DNAs are first transcribed into messenger RNAs in a process known as transcription and the resulting mRNAs are used in the synthesis of proteins in a process known as translation.
In eukaryotic cells, transcription process happens within the confines of the nucleus because the genetic material in the form of DNAs are always located in the nucleus. Thereafter, the mRNAs generated from transcription are transported to the cytoplasm of the cell where they become translated into proteins.
Hence;
- <em>T</em><em>ranscription</em><em> happens in the </em><em>nucleus</em><em> of the cell.</em>
- <em>Translation </em><em>happens in the </em><em>cytoplasm</em><em> of the cell.</em>
Answer:
Atmosphere
Explanation:
Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.
Answer: <u>Option B; It traps light energy and converts it into chemical energy.
</u>
This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.
This pigment is present only in plants, so option A is incorrect.
This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.
