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.

All of the alleles for the genes in a population is known as the
population's
A. Gene pool
B. Allele frequency
C. Evolutionary biology
D. Genetic drift
Answer:
Allele frequency
Explanation:
The collection of all the alleles of all of the genes found within a freely interbreeding population is known as the gene pool of the population. Each member of the population receives its alleles from other members of the gene pool (its parents) and passes them on to other members of the gene pool (its offspring)
All of the alleles for the genes in a population is known as the population's allele frequency.
What do you mean by allele frequency?The relative frequency of an allele at a particular locus in a population, expressed as a fraction or percentage, is known as allele frequency or gene frequency.
By dividing the total number of copies of each allele at that particular genetic locus in the population by the number of times the allele of interest is observed in a population, an allele frequency can be calculated.
Gene flow, natural selection, and genetic drift are the mechanisms that alter allele frequencies over time. A population breaks the Hardy-Weinberg assumptions when one or more of these forces are at work, leading to evolution.

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.

Question 4
A student is investigating cellular transport. What will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
A
The cell will swell because water will enter it.
B
The cell will swell because it will produce more sugar.
С
The cell will shrink because it has less water than the solution
D
The cell will shrink because it has less sugar than the solution
Answer: A . The cell will swell because water will enter it.
Explanation:
The cell will swell because it will undergo a process known as Osmosis.
Osmosis is a process where water molecules move from an area with a higher concentration of water to an area with a lower concentration across a semi-permeable membrane.
That semi-permeable membrane in this case is the cell membrane and because the cell has less water than the solution, water will flow into the cell thereby causing it to swell.

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.

How do tree grows in the forest without
human interference? Explain.
Answer:
Trees in the forest do not compete with grass for water and nutrients. Heavy equipment and other land uses are not present to contribute to soil compaction. The natural cycle of falling leaves and other natural waste decompose into fertilizer for plant and tree life. The forest floor is soft which allows easy penetration of life supporting elements.
The answer is very simple. Trees in the forest are not competing with grass for water and nutrients. Heavy equipment and other land uses are not available to contribute to soil compaction. The natural cycle of falling leaves and other natural waste is decomposed into fertilizer for plant and tree life. The forest floor is soft, allowing easy penetration of life supporting elements. In today's world, trees are being removed from their natural habitat and planted in newly developed residential or commercial sites. With soil compaction and grass competing, countless hours are spent trying to preserve nature in unnatural settings. Irrigation, aeration, soil modification are all necessary to help maintain a healthy root system. Strong healthy root systems make it easier for a tree to cope with pest, disease, and temporary drought. This is why you should be sure to call a qualified experienced arborist or consultant to diagnose and help you with your urban tree problems.

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.
