Answer:
Glucose mobilization would continue
Explanation:
The GTP-bound alpha subunit (Gαs) is a subunit of the heterotrimeric G protein which is required for stimulating the cAMP-dependent pathway through the activation of the membrane-associated enzyme adenylyl cyclase, which in turn catalyzes the synthesis of the second messenger cyclic-3′,5′-adenosine monophosphate (cAMP) from ATP. Moreover, cAMP phosphodiesterase is an enzyme that hydrolyzes cAMP, thereby negatively regulating the levels of this second messenger, which is fundamental for the termination of the signal. In this case, the epinephrine signal initiates glycogen breakdown (glucose mobilization) in muscle cells. In consequence, if the cAMP phosphodiesterase enzyme is inhibited, the concentration of cAMP will persist high even beyond the termination of the signal, thereby glucose mobilization would continue.
Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to the structures they supply. are found in the C6-T4 area of the vertebral column. extend through the sacrum. do not exist in humans.
Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
The anterior rami of the thoracic spinal nerves from T1 to T11 give birth to the intercostal nerves, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, directly connecting to the structures they supply.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

The project that you are working on was initiated in response to the growing threat of antibiotic resistance in both hospital and community settings. Even in the early discovery and development phase, it is important to think ahead to try to minimize the likelihood that bacteria will be able to evolve resistance to your new drug. Understanding how resistance emerges is an essential part of this process. What is true regarding the evolution of antibiotic resistance in bacteria?
Answer:
Decrease the effectiveness of this process.
Explanation:
Resistance emerges is an essential part of this process because this resistance causes decrease in the effectiveness of the drugs. If this resistance is not a part of this process, the microbes get resistance from the drugs which leads to lower the effectiveness of antimicrobial disease or infection so that's why resistance is considered as the essential part of this process of project.

D.
Answer: Air enters through the nose (and sometimes the mouth), moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi and bronchioles till the alveoli.
Explanation:The pathway of air in the respiratory system starts with the external organs of the nose and mouth.
Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.
Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea (windpipe) and the oesophagus (foodpipe).
Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.
Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs.
Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung.
Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air.
Alveoli:. Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.

Long strands of genetic information are stored in ________. A. Enzymes B. Adenine C. Chromosomes D. Mutations
The genetic information is the encoded proteins passed through hereditary. The genetic information is stored in the chromosomes of the cel. Thus, option C is correct.
What are chromosomes?Chromosomes are the hereditary unit of an organism that passes from the parent cell through cell division and reproduction to the daughter cells.
The chromosomes comprise chromatin that is made of the proteins and DNA molecules wrapped around the histones to form a dense and compact structure.
They look like long threads that are present inside the cell's nucleus and code for specific information that gives the genotype and phenotype of an organism. It gets copied during the cell cycle.
Therefore, option C. chromosomes store the genetic information.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.
Answer:
The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced
Explanation:
Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.
Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.

Why does population growth slow as size increases in the logistic model?
A : due to density-dependent factors
B : due to density-independent factors
C : due to a decrease in death rate
D : due to an increase in birth rate
Answer:
due to densinty dependent factors
Explanation:
because it determining energy requirement in human being
Population growth slow as size increases in the logistic model A : due to density-dependent factors is correct option.
In the logistic model of population growth, the slowdown in population growth as the population size increases is primarily attributed to density-dependent factors. Density-dependent factors are those that have a stronger impact on a population when its density (number of individuals per unit area) is higher. As a population grows and becomes more dense, competition for resources (such as food, space, and mates) intensifies, and factors like disease transmission and predation become more significant.
These density-dependent factors can lead to a decrease in birth rates, an increase in death rates, or both, which ultimately results in the population growth rate slowing down and eventually stabilizing at its carrying capacity (the maximum sustainable population size for a given environment). This pattern is characteristic of the logistic growth model, which describes a more realistic and sustainable form of population growth compared to the exponential growth model.

Answer:
Energy stored in plants is transferred to humans and animals that eat them
Explanation:
Students in a science class tested different plant seeds to determine how long it took each type of seed to fall from the second- story window of the school. They tested 100 seeds of each type in order to find out which type of seed had the the parent plant. The data they collected is shown in the chart below. which of these graphs best represents the students data?
walnut/0.6
maple/4.5
redoak/0.6
ash/2.0
pine/2.4
The correct answer is C.
Explanation
According to the information provided, a bar graph (option C) is needed since this type of graph allows us to express the variation in time, distance, temperature, quantities, weight, among others. In this specific case, a bar graph allows students to analyze the time that each type of seed takes to fall from the second floor. Additionally, this is the only graph that shows the data of the chart. For example, the first bar represents the black walnut and its time is 0,6 seconds, and this value is shown by the light blue bar in the graph, which represent the same seed. According to the above, the correct answer is C.
Uplift and formation of a mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the mountain range and brings the two populations together again, but when they mate, the resulting hybrids have sterile young. This is and example of which type of reproductive barrier
Answer:
Post reproductive isolation → Hybrid sterility
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.In the exposed example, sympatric speciation occurs. It seems that the mountains separating the snails´ populations made a place for speciation and the development of postzygotic barriers, specifically hybrid sterility. After the erosion process, both populations got to meet again. Snails from one population get to mate and produce offspring with the snails of the other population, but their progeny is sterile.

When DNA is copied, sometimes there are mistakes. Approximately how often does this
happen?
O A. There aren't any mistakes.
OB. 1 in a billion bases.
OC. 1 in a million bases.
OD. 1 in a trillion bases.
Reset Selection
Answer:
D. 1 in a trillion bases
Explanation:
A mutagen agent can change the genetic information of organisms increasing mutations over the natural level. Mutagens cause changes in the bases, and pairing bases, that compose DNI strands.
A mistake in the process of DNI copy during cell division might cause genetic changes in daughter cells. Defects DNI replication might be inherited if it occurs in germinal cells. But it can also cause many significant epigenetic changes.
Many of these changes can be detected on time by enzymes such as DNI polymerase. This enzyme can correct these mistakes or at least some of them, moving from 3´to 5´direction, and eliminating the mistakes.
The highly effective replication system, together with the action of enzymes, makes it rare to occur a mistake in DNI replication. Generally speaking, the mistaken rates in DNI replication are very low, meaning that only one in a trillion times occurs a mistaken DNI copy.
