The DNA sequence of the template or the bottom strand of an mRNA gene is 5-CCGGAATT-3. The sequence of the transcript will be 3-GGCCUUAA-5.
The base sequence in DNA and mRNA are complementary, and their alignment results in the production of mRNA. DNA bases A, T, G, and C pair with RNA bases U, A, C, and G, respectively, the sequence of mRNA is determined by the base pairing of RNA nucleotides with the DNA template strand. RNA is synthesized by complementary base pairing with the DNA strand in a process known as transcription.
DNA is made up of nucleotides with a sugar-phosphate backbone and a nitrogenous base, the nitrogenous base can be one of four nucleotides: adenine, guanine, cytosine, and thymine. In DNA, thymine is used in place of uracil, which is used in RNA. The complementary RNA strand is then synthesized by matching up the RNA nucleotides to the DNA template strand, this is what determines the sequence of mRNA. So therefore the sequence of the transcript in the given DNA template strand is 3-GGCCUUAA-5.

i. Sensory System
ii. Hormone and Chemical Coordination
iii. Photosynthesis
iv. Photoperiodism and Rhythmic Phenomena
v. Plant Reproduction and Development
Hormones and chemical coordination, and photoperiodism and rhythmic phenomena are two physiological systems that allow plants to respond to various stimuli. Hormones control the growth and development of plants, while photoperiodism regulates the day and night cycle.
Plants face various problems and physiological changes when their hormone and chemical coordination system is dysfunctional. The most common issue is the overuse of fertilizers and other chemicals, which can cause plants to be more susceptible to diseases. These substances can also cause plants to grow taller and faster, which can lead to weak stems that are more vulnerable to damage from wind and other environmental factors.
When photoperiodism and rhythmic phenomena fail, plants may face issues such as inappropriate flowering time, delayed growth and development, and difficulty adapting to changing environmental conditions. Plants that are exposed to light pollution, such as streetlights, may have their biological clocks disrupted, resulting in abnormal growth patterns.
The flowering time of plants is also influenced by photoperiodism, so when this mechanism is disrupted, plants may not bloom at the appropriate time. An example of a plant that relies on photoperiodism is soybeans, which require specific photoperiodic conditions to flower and produce seeds.

In science, models can show a process that’s difficult to observe directly. Using the style of the model shown, draw the process that describes the rest of the steps in protein synthesis.
The model is in the annex.
The model below states that following the transition, the RNA is in a form known as pre-mRNA where exons and introns may be seen. Splicing is a procedure used to eliminate introns from the RNA molecule since they are not nitrogenous base sequences that can contribute to the creation of proteins. When the introns have been eliminated, the mRNA is prepared for exportation, which involves moving it from the nucleus to the cytoplasm. When the mRNA reaches the cytoplasm, it works with the tRNA, ribosomes, and other molecules to produce a polypeptide chain through a process known as translation, which converts nitrogenous bases into amino acids.The amino acids of the polypeptide chain are arranged in a straight line.

match the step of a muscle contraction at the molecular level to the phase in which it would occur in a twitch.Myosin pulls (power stroke). :Acetylcholinesterase is released. :Calcium is released. :Calcium is actively transported. :Contraction phaseRelaxation phaseRefractory phaseLatent phase
Myosin pulls (power stroke) occurs in the contraction phase, acetylcholinesterase is released in the relaxation phase, calcium is released in the latent phase, and calcium is actively transported in the refractory phase.
The contraction phase is when the myosin crossbridges bind to the active sites of the actin, causing the filaments to slide and the muscle to shorten. During the relaxation phase, the calcium is removed from the actin-myosin complex, allowing the myosin heads to release and the muscle to relax.
The latent phase follows the relaxation phase and is characterized by a refractory period in which the muscle cannot be stimulated to contract until enough calcium is actively transported back into the muscle cell.
Lastly, the refractory phase occurs when calcium is actively transported back into the muscle cell, allowing the muscle to become responsive to stimulation again.

which scenarios are examples of reproductive barriers between closely related species that can cause reproductive isolation?
Reproductive barriers between closely related species include differences in mating behavior, gamete incompatibility, and developmental differences.
Reproductive isolation is the absence of gene flow between two populations or species, and it can be caused by various reproductive barriers that prevent interbreeding and the exchange of genetic material. Some examples of reproductive barriers between closely related species include: Differences in mating behavior, such as courtship rituals or mating calls, that prevent individuals of different species from recognizing or attracting each other as potential mates. Gamete incompatibility, which occurs when the sperm of one species cannot fertilize the eggs of another species, either due to differences in size, shape, or other physical attributes. These and other reproductive barriers between closely related species play a crucial role in promoting reproductive isolation and the eventual divergence of separate species from a common ancestor.

explain how high specific heat and expansion upon freezing sustain life
Life forms can keep relatively consistent interior temperatures because water has a high specific heat that makes them resistant to temperature changes. Water has a high boiling point due to its high specific heat and surface tension, which helps maintain its liquid for the majority of biological processes. Expansion upon freezing sustains life because Ice takes up more area than water because it expands (it is less dense). As a result, the ice floats on the water.
The specific heat capacity of a substance, also known as the massic heat capacity, is the heat capacity of a sample of the substance divided by the mass of the sample. Due to the thermal energy released by chemical processes within cells, specific heat aids in preventing organisms from overheating. When the outside temperature changes or rises, it aids organisms in maintaining a comparatively constant internal temperature.
Water crystallizes into an open hexagonal structure when it freezes, which accounts for the expansion that occurs. More room is there in this hexagonal lattice than in the liquid state. When water is cooled to a temperature of about 4 degrees Celsius, it begins to constrict as one would expect. It then gradually grows until it reaches the freezing point, at which point it freezes and expands by around 9%.
