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.

Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.”
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.

A) increased extracellular fluid water levels
B) decreased filtrate NaCl concentration
C) sympathetic stimulation
D) decreased stretch due to decreased blood pressure
Answer:
The correct answer is option A) increased extracellular fluid water levels
Explanation:
Juxtaglomerular granular cells are the group of cells present in the kidney that produce, store and release the enzyme known as the renin. These cells are present in the walls of the afferent arterioles mainly.
Renin is the enzyme release in order to release angiotensin I in order to increase the blood pressure. The release of the renin is depend on various triggers sense by juxtaglomerular granular cells such as decreased filtrate NaCl concentration , decreased stretch due to decreased blood pressure and sympathetic stimulation or other stimuli. However, increased extracellular fluid water levels is not responsible for the release of renin.

Answer:
The correct answers is "turn proteins "on and off" through changes in phosphorylation status".
Explanation:
Kinases and phosphatases are two type of enzymes that catalyze the transference of phosphate groups, where kinases add phosphate groups and phosphatases cleave them. Both are essential because turn proteins "on and off" through changes in the aforementioned phosphorylation status. Most of the phosphorylation are reversible, and they are considered as allosteric regulation
Kinase is an enzyme responsible for attaching phosphate groups to protein while phosphatases remove the attached phosphate group from the protein.
These two enzymes modulate the activity of a protein in a cell which is very important for cell functioning and communications.
The correct answer is:
Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.
The reason for the answer is:
Phosphorylase and kinase are the enzymes that catalyze the transfer of phosphate groups to the proteins.Kinases are responsible for adding phosphate groups while phosphatase cleaves them. They are antagonistic.They take part in the phosphorylation process of protein and are reversible.They regulate the working of protein by switching on and off with the help of these enzymes.Therefore, Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.

Why does the reduction of the dye DCPIP work best using the chloroplasts whose outer envelopes have been damaged during preparation?
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.

Sensitivity remains constant
Sensitivity decreases over time
Nociceptors continually detecting pain
Answer:
The cells of the ear detect these the position of the head: proprioceptors are guided in the hydrostative pressure and the movement of the intracochlear fluid with the movement. That is why it complies with the following statements: Sensitivity remains constant, Responds to change (we say that it responds to change because when changing position the intracochlear fluid is where the movement of the head is perceived).
The proprioceptors of the epithelial cells (MERKEL CELLS. THEY ARE THE ONLY SENSORY CELLS TOGETHER WITH THOSE OF LANGERHANS), are proprioceptors that capture different textile textures that contact the skin. But throughout our lives this sensitivity decreases, that is why it complies with the following statements: Responds continuously, Sensitivity decreases over time, nociceptors continuously detect pain (to be able to perceive if the innate protective barrier that is epithelial continuity is damaged, since in the face of damage or discontinuity due to a cut or injury we are unprotected by the innate epithelial defense barrier).
Explanation:
I hope the answer has served you, the body's proprioceptors are everywhere and are receptors specialized in capturing very fine stimuli, that is why they are considered proprioceptors with a very low uptake threshold.
The textural propipceptors that are epithelial, or pain, are different from those found in the ear.
