Explanation:

Genetics and Genomics are two terms that are used commonly in molecular biology but mean entirely different things.

Genetics is the study of individual (single) genes and their role in genetic inheritance i.e. heredity while Genomics is the study of all the genetic composition of an individual (genome) and how they interact with one another and their environment.

Based on the explanation above,

- the study of individual gene is classified as GENETICS

- study interactions between many genes is classified as GENOMICS

- study of DNA, which contains all the genes of an individual is classified as GENOMICS

- sequencing the genome of organisms is classified as GENOMICS.

- control of gene expression is classified as GENOMICS because it involves expression of information in the genes, which is a branch of genomics called functional genomics

- observing mutant effects across the genome is classified as GENOMICS

Classify each action as belonging to genetics, genomics, or both.

a. Study individual gene - Genetics

b. Study interactions between many genes - Genomics

c. Study DNA - Both (primarily Genetics)

d. Sequence genome of organisms - Genomics

e. Control gene expression - Genetics

f. Observe mutant effects across the genome - Genomics

Therefore, the correct options for A, B, C, D, E and F are 1, 2, 3, 2, 1 and 2 respectively.

Individual genes are the main subject of genetics, which also looks at how they are transmitted among populations as well as their structure, function, and variations. It involves examining the genetic information and traits that are transferred from one generation to the next.  When studying the relationships between multiple genes and their overall effects on an organism, genomics takes a macro approach.

Therefore, the correct options for A, B, C, D, E and F are 1, 2, 3, 2, 1 and 2 respectively.

Answer:

The formation of one isochromosome

Explanation:

In cytogenetics, an isochromosome is a structurally abnormal chromosome that renders two chromosome arms which are identical inverses of each other. An isochromosome is caused by simultaneous duplication and deletion of genetic information during DNA replication. The resulting isochromosome will contain two identical copies of either the long or short chromosome arms that are disposed as a mirror image.

Answer:

NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer  electrons  in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+

These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid  intramembranes.

Outer membrane covers  the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of  the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.

The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope. 

Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.

Thus   the rate of reduction of DCPIP is faster.The  color changes to colorless increases when reduced , from blue color.

Explanation:

The reduction of the dye DCPIP (2,6-dichlorophenolindophenol) works best using chloroplasts whose outer envelopes have been damaged during preparation because it allows easier access for DCPIP to the electron transport chain (ETC) components.

The outer envelope of chloroplasts contains phospholipid bilayers that act as barriers, limiting the movement of molecules in and out of the chloroplasts.

When the outer envelopes are damaged, DCPIP can diffuse more freely into the chloroplasts and come into contact with the ETC components, particularly photosystem I.

DCPIP acts as an electron acceptor, and in the presence of light, it is reduced by electrons from photosystem I, resulting in its color change from blue to colorless.

The damaged outer envelopes facilitate the interaction between DCPIP and the ETC, leading to more efficient reduction.

This question seems to be incomplete because the experiment is not described but it is possible to answer it.

The correct answer is B. Redi disproved spontaneous generation.

Explanation:

Francesco Redi was an important scientist during the 17th century known for his experiments about maggots in rotten meat. This is because during Redi's time it was believed rotten meat was the origin of maggots because maggots seemed to emerge from this. Additionally, this perception was related to the spontaneous generation or the idea life can emerge from non-living materials. The results of this experiment show the idea about spontaneous generation was not true in the case of meat and maggots because maggots were simply the result of eggs flies laid on rotten meat. This means this experiment disproved spontaneous generation.

Answer:

Cellular organization and metabolism are two items necessary to consider an organism alive.

Explanation:

There are certain characteristics that belong to living beings and that they all have in common. These are distinctive characteristics that do not include any non-living object. Among others, we can name the followings:

1) Precise cellular organization. The cellular theory states that every living being is conformed of basic units named cells and their products that result from the cellular activity. Although organisms vary in size and shape, all of them are formed by cells. A cell is the simplest part of the living matter which is capable of performing every necessary activity needed for life. Some of the simplest organisms, such as bacterias or some algae, are unicellular. This unique cell must be polyfunctional, as it has to perform many activities. On the other hand, many other organisms are highly complex pluricellular. All the processes of the entire organism depend on the correct and coordinated functioning of every constituting cell. The more complex the organism is, the more specialized are the cells, differentiating from each other, and acquiring certain specific functions. These are, for example, the epidermic cells, muscular cells, nervous cells, reproductive cells, among others.

2) Metabolism. In any living being there happen many essential chemical reactions needed for appropriate nutrition, growth,  cellular repairing,  energy conversion, among others. All of these chemical reactions in the organisms are known as metabolism. These cellular activities begin when the organism takes life, and continue through its whole life. When chemical reactions stop, the organisms might be considered to be dead. Every specific cell in the organisms take substances that chemically modify, in many different ways, to integrate new cellular components.  Some of these nutrients are used in cellular respiration. During this process, part of the energy stored is taken by the cell for its own use.  This energy is also needed for synthesis and other cellular activities. In most organisms, cellular respiration requires oxygen provided by the gas interchange. Cellular wastes, such as carbon dioxide and water must be eliminated from the organism. Every chemical reaction is regulated by specific enzymes.

Based on the information provided, the graph, and the timeline, the statement that best describes the growth of the human population is: The population's growth rate is increasing exponentially, as in Option C.

This rapid increase in the human population over the past few centuries is often attributed to advances in technology, medicine, and agriculture. These advances have made it possible to sustain a larger population by increasing food production, improving sanitation, and reducing mortality rates. As a result, the human population has grown at an exponential rate, with the rate of growth increasing over time. However, it is important to note that the rate of growth may eventually slow down as the population approaches its limit, and there may be various limiting factors such as resource availability, climate change, or disease outbreaks that could affect population growth in the future.

Hence, the correct answer is: "The population's growth rate is increasing exponentially," which is in Option C.
