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

blood can receive Rh+ or Rh-blood.
blood can receive Rh-blood.
Answer: An Rh+ person can receive Rh+ or Rh-. An Rh- person can only receive Rh- blood
Explanation: the Rhesus (Rh) group has three types, CDE. Of these, only the D locus is of general importance, and this is the one involved when we talk about Rh+ or Rh-. The D allele is dominant and DD or Dd are the Rh+ type, while dd is Rh-.
Rh- people have an immune response to the D and produce antibodies which causes blood clots and this can be life-threatening. Some Rh- people have anti-D antibodies in their blood, but the level is too low to affect Rh+ people transfused with Rh- blood. This is also unlikely because Rh+ is by far the more common type.
A particular problem arises when a mother is Rh- and the father Rh+ because the baby may be Rh+. If this happens the mother will produce antibodies to the foetus’s blood which will kill it if they cross the placenta. This is avoided by giving the mother Rh immunoglobulin injections during pregnancy which switch off anti-D antibody production.
It is rare for the C and E loci to cause a significant immune response.

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.

Which evolved first, photosynthesis or cellular respiration?
Answer:
Because photosynthesis is a source of oxygen, it seems intuitive that photosynthesis evolved first: once enough O2 was in the air, then respiration would be able to arise in the newly oxygen-enriched atmosphere. However, some biologists have argued since the 1970's that respiration in fact evolved first.

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.
