which of the following is least affected by seasonal environmental conditions?
Answer:
The seasonal environmental conditions are very poor , during summer season temperatures are very high.
The organism that is least affected by seasonal environmental conditions is a bacterium, as bacteria are single-celled prokaryotes that are capable of adapting to a wide range of environmental conditions.
What is the significance of bacterial and plant living conditions?Bacteria can survive in extreme conditions such as high salinity, low pH, and other environmental conditions and can easily switch from aerobic to anaerobic metabolism depending on the availability of oxygen in the environment. Plants and animals are more sensitive to seasonal environmental conditions as they need temperature, light, water, etc.
Hence, the organism that is least affected by seasonal environmental conditions is a bacterium, as bacteria are single-celled prokaryotes that are capable of adapting to a wide range of environmental conditions.

A drought is a period of unusually low
rainfall. A farmer notices that a well on the farm stops providing water
during a drought. A nearby lake also
has less water in it than usual. Write a
couple of sentences that explains
what has happened to the water table
in the area to cause these results.
In the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.
What is drought?Drought may be defined as a brief period of abnormally dry weather sufficiently prolonged for the lack of water to cause a serious hydrologic imbalance in the affected area.
During severe droughts, people depend heavily on groundwater—the water held underground in aquifers. During these periods, the rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth of water in wells gradually increases.
Therefore, in the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.

Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer:
A and B
Explanation:
the other 2 answers are just obviously wrong
They are both models of the solar system and they both show the position of the Earth relative to the sun. So the correct option is A and B.
What are heliocentric and geocentric models?A cosmological concept known as heliocentrism assumes that the Sun is located at or close to the center of the solar system or the universe, with the Earth and other planets revolving around it. The Greek philosophers Philolaus and Hicetas hypothesized independently that the Earth was a rotating sphere that rotated daily around a mysterious "central fire" that controlled the cosmos in the fifth century BC.
Two hundred years later, Aristarchus of Samos expanded on this concept by stating that the Sun, together with the Earth and other planets, revolved around a certain central object.
Any solar system (or universe) structure hypothesis that places Earth at the center of the cosmos is referred to as a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced (2nd century CE). It was widely believed until the 16th century when heliocentric theories like Nicolaus Copernicus took their place.
Therefore the correct options are A and B.

What is protein translation?After the process of transcription of DNA to RNA in the cell's nucleus, ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins. The entire process is referred to as gene expression.
The translation of ribosome of mRNA molecule occurs in three stages: initiation, elongation, and termination. The small ribosomal subunit binds to the beginning of the mRNA sequence during initiation.
The t RNA plays a role in protein synthesis by decoding an mRNA codon and using its anticodon to transfer a specific amino acid to the end of a chain in the ribosome.
Transfer RNA connects the messenger RNA (mRNA) molecule to the growing chain of amino acids that makes up a protein.
Thus, the correct option is B.

How does energy transfer from the hot water to the cold air
Answer:
humidity and evaporation
Explanation:
1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.

Different mechanisms of reproduction exist within the same species.
Different metabolic pathways exist within the same species.
Different species have the same genetic code.
Different species have the same number of chromosomes.
Answer:
1. Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
2. Anabolism & Catabolism
3. Nearly everybody has the same genetic code. Although the sequences of bases in their DNA (and thus in the messenger RNA that is made from their DNA) vary between species and even between individuals within a species, almost all of them use the same code.
4.Yes, two or more species can have the same number of chromosomes. ... There's much more to differentiating between species than number of chromosomes. For one example, there are proteins present on eggs which 'match up' with proteins on sperm, and these are very specific.
