1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.
2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.
3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
The climate of the tropical zone characterized by a very wet season alternating with a very dry season is wet/ dry topical climate.
In the us- Anchorage, Alaska because the natural environment is far more resilient to a major weather event than a large city setting and can better adapt to changing sea levels or temperatures. With less people and man-made infrastructure, there are fewer things to be maintained in the area, allowing the wilderness to react naturally to changing weather patterns and climate.
outside the us- Denmark because the country has continued to make strides forward, in air quality in particular. On the previous report, 78.8% of the population was exposed to unsafe levels of fine particle air pollution; now, the figure has dropped to 56.9%. Denmark tops the list of countries doing the most to protect the environment, among them having at least half its energy consumption come from renewables by 2030 and to be independent of fossil fuels by 2050.
The correct answer is E. Algae and Fungi
Explanation:
In biology, some groups of organisms are exclusively unicellular which means all organisms of the group are made of one cell, some are exclusively multicellular which means all organism are made of two or more cells and in some cases in a group there can be both single-celled and multicellular organisms which occur in both algae and fungi. Indeed, in these two groups, there are unicellular organisms as Chlorella (algae) or yeast (fungus) that contain only one cell and multicellular organisms such as Kelp (algae) or regular mushrooms (fungus) that are both multicellular. On the other hand, protozoa only contain unicellular organisms. This means the groups that contain single-celled and multicellular organisms are algae and fungi.
Answer:
3' to 5'; 5' to 3'
Explanation:
The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA. The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.
