Answer:
Parasympathetic
Explanation:
The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations. The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination. That is why the Parasympathetic Nervous System is being used in this scenario. Hope this helped :)

The predatory bacterium Bdellovibrio bacteriovorus drills into a prey bacterium and, once inside, digests it. When the predatory bacterium attacks the gram-negative bacterium, what are the first structures penetrated by B. bacteriovorus on its way into the prey's cytoplasm
Answer:
The outer membrane, a peptidoglycan layer, periplasm, and cell membrane
Explanation:
The predatory bacterium will have to penetrate the cell wall and the cell membrane of the gram-negative bacterium before getting access to the cytoplasm.
In order to penetrate the cell wall of a gram-negative bacterium, the predatory bacterium will have to penetrate the components of the cell wall which consists of an outer membrane, a thin peptidoglycan layer, and a gel-like matrix known as the periplasm.
Thereafter, the predatory bacterium will have to penetrate the cell membrane before eventually getting access into the cytoplasm of the prey bacterium.
The peptidoglycan layer or the outer membrane will be the first structure penetrated by the B. bacteriovorus.
The attack of the predatory bacterium on the other bacterium:In the given case, the predatory bacterium, that is, B. bacteriovorus needs to penetrate the cell wall and the membrane of the gram-negative bacterium prior of getting within the cytoplasm of the host bacterium.
To penetrate the cell wall of a gram-negative bacterium, the predatory bacterium have to infiltrate the cell wall components comprising,
An outer membranePeriplasm, that is, the gel-like matrixA thin peptidoglycan layerThus, the predatory bacterium will first have to penetrate the peptidoglycan layer of the gram-negative bacterium.

What happens when organisms populate a new area and are isolated geographically from other populations of the same species?
Answer:
The geographically isolated population will acquire genetic differences that eventually will lead to its speciation
Explanation:
Geographic isolation is a biological process produced by the physical separation between organisms of the same species, which may be caused by different types of geographical barriers such as, among others, mountains, earthquakes, rivers, etc. Geographic Isolation produces genetic differences between the separated groups. Over time, these genetic differences will lead to the reproductive isolation of the new population, thereby leading to the formation of a new species in the course of evolution, in a mechanism referred to as speciation.

Chloe is studying the effect a certain kind of fungus has on bacteria. Which of the following could be her hypothesis?
"I notice that when a certain fungus is present in a bacterial culture, the bacteria do not grow".
"Based on my tests, I realize that this fungus kills bacteria".
"I predict that the bacterial cultures in which I place this fungus will not grow".
"I propose that this fungus somehow kills bacteria."
Answer:
I propose that this fungus somehow kills bacteria
Explanation:
you rule out 2,3 because a hypotheses has not yet been proven therefore it is not certain
while in 1 in some cases the bacteria can also over power and kill the fungi using genes
but I chose 4 since fungi lack chloroplasts so they feed of ready made food and bacteria can be autotrophic therefore can manufacture food and so the fungi digests the bacteria in the process of trying to acquire the food since they don't have cell walls I guess

In the late 1870s, Charles Darwin and his son Francis discovered that if the tip of the grass was covered, phototropism did not occur, even though the rest of the grass was exposed to light. However, if the rest of the plant was covered and only the tip exposed to light, the grass bent a few centimeters below the tip. How could light striking the tip of the grass cause bending a few centimeters from the tip
Answer:
The summary of the particular subject is provided in the segment below on clarification.
Explanation:
Noticed that saplings of the plant would still curve forward into light unless the tip of their ranges were available. The crop developed straight ahead as they cut the edge of such a grass crop, instead of just rotating forward towards the ground.The target stayed straightforward as they put an opaque caps over its end. However, when individuals positioned a transparent caps on its own edge, or perhaps an opaque mask over its core, it streamlined.This was found that perhaps the shoot's tip was essential to detect light. Acknowledged that although the answer to development, trying to bend the shooting, actually happens beneath the tip. A certain message was conveyed downwards from either the service charge to the take the shot's growing market.Recall that two hydrogen bonds bind A and T, but three hydrogen bonds bind G and C.

a. computer-generated DNA sequence.
b. freeze-fracture replica.
c. prediction of glycosylation sites.
d. Western blot.
e. hydropathy plot.
Answer:
The number and location of transmembrane segments in an integral membrane protein can be inferred from the amino acid sequence of the protein by a computer-generated hydropathy plot (which is actually a combination of option A and E)
Explanation:
The hydropathi plot is something that enable us to measure the hydrophilicity or hydrophobicity of amino acids in a protein. The computer-generated hydropathy plot identifies the number and location of transmembrane segments. There are plenty of proteins in cells membranes that play different roles and functions. Some of them react to different ph, others with different minerals and other react to water.
Protein molecules are found in the lipid bilayer structure of the plasma membrane. The proteins are found as integral or peripheral proteins.
The location and the number of transmembrane segments can be given by:
Option e. Hydropathy plot
The technique can be explained as:
The hydropathy plots are capable of determining the position and the quantity of the integral membrane protein.It enables measuring the hydrophobic and hydrophilic sides of amino acids of proteins. This enables in identifying the property of the side chain amino acid.Therefore, a hydropathy plot should be used.

Is the escape of a rattlesnake from a zoo exhibit an example of an invasive species?
Answer:
No, it isn't
Explanation:
An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.
Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.
A blood lactic acid sample was collected in a gray-top tube that was drawn after sequentially filling red-top, green-top, and purple-top tubes. The lactate level was 30 mg/dL. A second lactic acid sample was ordered 1 hour later and drawn in a gray-top tube without filling any other tubes. The result was 20 mg/dL. What is the most likely explanation of this result
Answer:
Homeostasis has been established for a very long time. This must have affected the result of the first reading, which has become high.
Explanation:
Homeostasis refers to the state of equilibrium in the chemical and physical conditions of a system. The time it takes to establish, as well as the time it remains active within a system, provides different results, which are totally related to the homostatic forms presented.
The time between homeostasis in the blood lactic acid samples shown in the question above was what allowed the difference between the two reading results. The first result was high, because it was the result of an extended period of homeostasis.

which following pairs of body functions are normally involuntary actions but can be controlled voluntary for a short periods of time
Explanation:
Medulla oblongata controls consciousness and arousal (the reticular formation) and its three vital reflex centers control the blood vessels diameter, heartbeat and breathing rate (the involuntary actions). This makes option D correct. The lower part of brain stem forms the hind brain which comprises of medulla oblongata, pons and cerebellum. This makes option C incorrect as medulla is not part of forebrain. Cerebellum is the convoluted subdivision of brain stem and is associated with coordination of muscular movement, muscle tone and balance i.e. the voluntary actions. Option B is incorrect. Spinal cord, along with brain, forms central nervous system which serves to integrate the sensory inputs from internal and external environment as received by sensory neurons and process and finally transmit the nerve impulses to effectors (muscles and glands). This makes option A incorrect.

Explanation:
The respiratory and circulatory systems deliver oxygen and eliminate metabolic waste. It controls blood pH. Respiration exchanges oxygen and carbon dioxide between the atmosphere and bodily cells.
What is respiration?The passage of oxygen from the outside environment into the cells of the tissues is what is referred to as respiration in the field of physiology. At the same time, carbon dioxide is removed from the tissues and released back into the environment.
Together with the circulatory system, the respiratory system is responsible for supplying the body with oxygen and removing waste products from the metabolic process. Additionally, it helps to maintain a healthy pH level in the blood. The process by which oxygen and carbon dioxide are transported from the outside environment into the cells of the body is called respiration.
