Which of these tasks would a hydrologist be most likely to perform?
A. Determining the species of a recently collected specimen
B. Estimating the age of recently discovered fossils
C. Estimating the amount of groundwater in an aquifer
D. Determining the best method to extract underground oil
Hydrologists are most likely to perform actions relating to estimating the amount of groundwater in an aquifer.
HydrologistsHydrologists are scientists that specialize in the study of how water relates to the various crusts of the earth.
Hydrology in itself refers to the branch of science that studies how water moves relative to the earth's crusts.
Thus, species identification, age of fossils, or extracting underground oils have nothing to do with the work of hydrologists.

Which best describes how the photosystems are used in the light-dependent reactions?
photosystem I is used first then photosystem II
photosystem II is used first then photosystem I
Both processes are used at the same time.
Both processes are used during the light-independent reactions.
Answer:
B. photosystem II is used first then photosystem I
Photosynthesis is a series of metabolic reactions that convert sunlight, water and CO2 into sugar and oxygen. The reactions in photosynthesis can be divided into light-dependent and light-independent reactions.
The statement "photosystem II is used first then photosystem I" BEST describes how the photosystems are used in light-dependent reactions.Photosystem I (PSI) and photosystem (PSII) are protein complexes localized in the thylakoid membrane of the chloroplast.During light-dependent reactions, energy from sunlight is absorbed by chlorophyll of the photosystems. Subsequently, this energy is then converted into chemical energy (ATP and NADPH), a process that involves the transference of electrons.Both photosystem I and photosystem II contain pigments to collect sunlight energy and a reaction center in which excited electrons can be transferred from chlorophyll to an electron acceptor.Photosystem II is upstream in the electron flow pathway, but this photosystem (PSII) was discovered after photosystem I.Subsequently, electron flow is coupled to the generation of an electrochemical proton (H+) gradient across the thylakoid membrane, which is used to synthesize ATP by an ATP synthetase.In conclusion, the statement "photosystem II is used first then photosystem I" BEST describes how the photosystems are used in light-dependent reactions.

Proteins in the cell membrane that identify the cell are called
A. enzymes
B. transport proteins
C. cell-surface markers
D. receptor proteins
Answer:
Proteins in the cell membrane that identify the cell are called cell-surface markers (option C).
Explanation:
Cell surface markers are integral membrane proteins, whose function is to identify specific cell lines, allowing intercellular recognition and communication.
The specific type of cell marker provides the basis for cell classification, allowing studies to be performed on immune system cells, stem cells or atypical cells such as those found in cancer.
The other options are not correct because:
A. Enzymes are proteins that participate in metabolic reactions.
B. Transport proteins, although they are also part of membrane proteins, perominate the passage of specific substances through the membrane.
D. Receptor proteins allow the identification of specific molecules, such as hormones, to couple with them and promote actions inside the cell.
Proteins in the cell membrane that identify the cell are called CELL-SURFACE markers (Option C).
Cell surface markers are specific proteins localized on the cell surface or glycoproteins, which can be used as molecular markers that evidence specific cell types/lineages.
For example, cell surface markers can be used for the identification of the lineage and/or phase of differentiation in lymphocytes such as T cells and B cells.
In lymphocytes, the cell surface markers can be divided into three classes: surface immunoglobulins, differentiation antigens, and membrane receptors.
In conclusion, proteins in the cell membrane that identify the cell are called CELL-SURFACE markers (Option C).
