Match the following DNA strand to its complementary strand of RNA
TTA - CAA - ACC - ATA
Question options:
AAU - GUU - UGG - UAU
AAT - GTT - TGG - TAT
AAU - CTT - TGG - TAT
ATG - CCG - AAT - TCG
Answer:
AAU - GUU - UGG - UAU
Explanation:
Thymine is present in RNA strands as the base Uracil, making there an inability to have Thymine in an RNA strand.
Hope this helped :)
Answer:
The first option: AAU - GUU - UGG - UAU
Explanation:
RNA has the nitrogenous bases adenine (A), uracil (U), guanine (G), and cytosine (C). A pairs with U while G pairs with C. The thymine (T) from the DNA must be complemented by the adenine (A) from the RNA, too.
Knowing this, the complementary strand of RNA would be the first option. Another way of finding the answer would be noticing that all the other options have thymine (T), which is a nitrogenous base RNA does not have.
Why is the controlled timing of gene expression crucial to an organism?
It allows for differentiation.
o It allows for specialization.
O It allows for development.
all of the above
The controlled timing of gene expression is crucial to an organism because it allows for differentiation, specialization, and development. Thus, the correct option is D, i.e. all of the above.
What is Gene expression?Gene expression may be defined as a process through which a cell utilizes several functional gene products to synthesize RNA and then functional proteins.
Gene expression mediates the process of differentiation and specialization of all functional proteins that are synthesized at particular target sites.
The completion of gene expression also allows the cell to divide functionally and provokes the growth of cells to facilitate development.
Therefore, the correct option for this question is D.

What is the role of shell-building marine creatures in regulating climate?
A.
their shells form the hydrocarbon fuels that release greenhouse gases when burned
B.
they utilize the carbon dioxide released while respiring to build their shells
they help to remove carbon dioxide through calcification
D.
they help to remove carbon dioxide through photosynthesis
Answer:
they help to remove carbon dioxide through calcification
Explanation:
The correct answer would be that they help to remove carbon dioxide through calcification
Shell-building marine creatures play important roles in regulating climate because they help to remove carbon dioxide from the environment through the process of calcification.
Carbon dioxide is a major driver of climate change because the gas is among the greenhouse gases that absorb radiation from the sun thereby causing the warming of the planet. The more the carbon dioxide in the atmosphere, the more the amount of heat trapped and the more the increase in the global temperature. An increase in the global temperature causes the general climatic factors to become erratic.
Hence, the removal of carbon dioxide through the process of calcification is important for regulating climate change.
Answer:
c.they help to remove carbon dioxide through calcification

4. What role do the muscles and blood vessels play in the negative feedback loop of thermoregulation?
A) integration centers B)sensors
C)stimuli
D)effectors
Answer:
D)effectors
Explanation:
Skeletal muscles constitute an additional effector in this feedback loop because they quickly contract in response to a drop in body temperature, hence option D is correct.
What is a negative feedback loop of thermoregulation?Blood flow is decreased, and the environment loses less heat as a result because blood vessels close to the skin constrict. Shivering helps the body produce heat, which raises body temperature.
The body starts to sweat when the hypothalamus senses that it is too hot, trying to bring the body's temperature back down to normal. Sweating will cease after the body temperature has returned to normal.
Therefore, the muscles and blood vessels play as effectors in the negative feedback loop of thermoregulation, hence option D is correct.

Which statement best describes the interdependence of photosynthesis and cellular respiration?
A. The reactants of photosynthesis are sugar and oxygen to be used in cellular respiration B. The products of photosynthesis are carbon dioxide and water to be used in cellular respiration
C. The reactants of photosynthesis are the products of cellular respiration
D. The products are the same as the products of cellular respiration
Answer:
C.
Explanation:
Photosynthesis: reactants are CO2 and H20
products are O2 and Sugar
Cellular respiration: reactants are O2 and Sugar
products are C02 and H20
so they are swapped
The statement best describes the interdependence of photosynthesis and cellular respiration is the reactants of photosynthesis are the products of cellular respiration. Hence option C is correct.
What is cellular respiration?Cellular respiration is defined as the process through which organisms mix food molecules with oxygen, directing the chemical energy in these molecules toward life-sustaining processes while eliminating carbon dioxide and water as waste products. A metabolic process called cellular respiration converts glucose to ATP.
The reactant of photosynthesis is CO₂ and H₂O and the product is O₂ and sugar. While the reactant of cellular respiration is O₂ and sugar and product is CO₂ and H₂O. The reaction of cellular respiration is just reverse of the reaction of photosynthesis.
Thus, the statement best describes the interdependence of photosynthesis and cellular respiration is the reactants of photosynthesis are the products of cellular respiration. Hence option C is correct.

Explain how paleoclimatologists (scientists that study climate change) use fossils and other records to study climate change.
Answer:
paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)
Explanation:
Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.
