15. The model includes a wavy arrow to show light striking the thylakoids. Which
label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
This question is incomplete as it lacks the model, however, it can be answered based on general understanding of photosynthetic process. The answer is;
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Light dependent reaction, which is the first stage of photosynthesis, occurs specifically in the THYLAKOID of the CHLOROPLAST where the photons of light is absorbed by chlorophyll molecules (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis and the most useful way for communicating the role is by saying it provides the energy source for converting ADP to ATP, and NADP+ to NADPH.

4. Which of the following elements does not want to have eight valence electrons? a. magnesium c. hydrogen b. oxygen d. nitrogen
Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.
Hence, Hydrogen is an element which does not want to have eight valence electrons.

22. The table that the scientist constructed does not include light. Describe the role
of light in the
scientist's experiment. Then propose an explanation for why light
was not included in the table.
a. Light provides the energy for the chemical reactions that take place during
photosynthesis, and the table includes only matter, not energy.
b. Light provides the matter for the chemical reactions that take place during
photosynthesis, and the table includes only energy, not matter.
c. Light is a product of the chemical reactions that take place during
photosynthesis, and the table includes only reactants, not products.
d. Light plays no role in the scientist's experiment and therefore was not
included in the table.
Answer:
a. Light provides the energy for the chemical reactions that take place during photosynthesis, and the table includes only matter, not energy.
Explanation:
Photosynthesis is the process by which plants and certain organisms produce their food (glucose). The photosynthetic process, which occurs in stages, uses LIGHT ENERGY from sun in the first stage called light dependent reaction.
LIGHT is pivotal to the process of photosynthesis as it serves as the energy source for the chemical reactions that synthesizes ATP and NADPH, which are products of the light stage of photosynthesis. However, based on the table in the attachment of this question, it only contains matter as reactants and products and not ENERGY.

A
Transmission of genetic information
(Choice B)
B
Enzyme function
(Choice C)
C
Energy storage
(Choice D)
D
Membrane structure
Answer:
the right answers are Energy storage and Membrane structure
Choice C and D Lipids are a group of molecules that are important for a variety of biological functions. They are essential components of cell membranes, can act as energy storage molecules, and can be used as signaling molecules.
What is the importance of lipids ?
Lipids are also important for membrane structure, as they form the hydrophobic core of the membrane, which is essential for the proper functioning of the cell.
Lipids also play a role in enzyme function, as they are used in the formation of enzyme active sites and can act as cofactors in some enzyme reactions.
However, lipids do not play a role in the transmission of genetic information. That is correct. Lipids are a diverse group of molecules that serve numerous functions in the body, but they are not involved in the transmission of genetic information.
Therefore, The transmission of genetic information is mainly mediated by nucleic acids such as DNA and RNA. Lipids, on the other hand, are involved in a variety of other important biological functions, including energy storage, signaling, and membrane structure.

How are meiosis and mitosis different?
Answer:
Meiosis is a type of cell division that results in the formation of four daughter cells each with half the number of chromosomes as the parent cell. on the other hand Mitosis is the type of cell division that results in the formation of two daughter cells each with the same number and kind of chromosomes as the parent cell. hope this helps a bit

describe how water moves from the soil to the leaves in a tree
Answer:
Cohesion/adhesion
Explanation:
Water is passively transported into the roots and then into the xylem. The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Ocean salinity varies from place to place due to differing conditions in the environment
-true
-false
Ocean salinity varies from place to place due to differing conditions in the environment is a true statement.
How ocean salinity varies?It is not evenly distributed, but it does change temporarily and spatially with the oceans and seas.
This variation is both horizontally and vertically distributed; horizontal distribution refers to salinity changes at the ocean's surface level and vertical distribution, to salinity changes as the ocean's depth.
Several variables influence ocean salinity. They are global warming, evaporation, rainfall, river water input, ocean currents, atmospheric pressure, and wind direction. Oceans and seas have a 35 average salinity.
Therefore, It is not evenly distributed, although it does change momentarily and spatially with the oceans and seas.

What are the stages of meiosis in eukaryotic cells with realizing that there are two cell divisions involved?
Answer:
Meiosis can only occur in eukaryotic organisms. It is preceded by interphase, specifically the G phase of interphase. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.
