The hormone which causes the shoot to respond to directional light is auxin.
Phototropism is the process by which plants respond to light by growing toward or away from a light source. Growing toward a light source is known as positive phototropism, whereas growing away from light is known as negative phototropism.
In general, the above-ground or shoot portions of plants exhibit positive phototropism or bending toward the light. This reaction assists the plant's green portions in moving toward a source of light energy, which may subsequently be utilized for photosynthesis. On the other hand, roots will often develop away from light.
The primary photoreceptors involved in phototropism are proteins referred to as phototropin. In response to phototropin activation, auxin, a plant hormone, is carried unequally along the two sides of the coleoptile. Auxin encourages cell elongation, which makes the plant grow more on the shaded side and bend toward the light source.

happens to the volume (V) of
the sample?
As pressure increases, the volume of the sample decreases.
As we know according to Boyle's law volume and pressure are inversely proportional.What does Boyle's law state?Boyle's law states that,
"The absolute pressure exerted by a given mass of an ideal gas in a closed system with constant temperature and gas volume is inversely proportional to the volume it fills."
It represented as P1V1=P2V2
What are some of the real-life examples of Boyle's law?When you inflate your bicycle tires, you can see how Boyle's Law is used in practice. The gas molecules inside a tire are squeezed and crammed closer together when air is pumped into it.

A) Enzymes gain heat from chemical reactions.
B) Enzymes use light energy to speed up chemical reactions.
C) Enzymes lower the activation energy of a reaction.
D) Enzymes change shape during chemical reactions.
The statement that best explains how enzymes speed up chemical reactions is "Enzymes lower the activation energy of a reaction." (Option C)
How does the above work?Catalysts are another name for enzymes. They accelerate the process by decreasing the activation energy of the reaction. This suggests that they are hastening the chemical processes.
The lowest amount of energy required by a reactant to produce an activated complex in order to launch a chemical or nuclear reaction is referred to as activation energy.
As a result, enzymes accelerate chemical processes by decreasing the activation energy.

Marcus really wants to ask Amy for a date but begins to sweat uncontrollably and finds
it hard to speak every time he even gets near her. Choose any three psychological approaches and describe how each might explain Marcus's behavior.
Psychological approaches that describe Marcus's behavior are Psychological sweating.
Psychological sweating is a physical reaction we attempt to suppress or, in the worst case, hide. Psychological sweating occurs all over the body surface in response to emotional stimuli including stress, anxiety, and pain, although it is particularly noticeable on the palms, soles, face, and axilla. High eccrine sweat gland concentrations at various bodily areas are mostly to blame for this. Eccrine sweat glands are activated by cholinergic innervation as the main effector during times of intense psychological stress.
73% of the approximately 800 men who participated in a Men's Health study stated they wished they could sweat less. Our romantic partners would like it if we did too: 84% of the 970 women surveyed thought it was disgusting when a man dews up on a date. "Sweating without command is like your body betraying you,"
Our bodies have apocrine and eccrine sweat glands. A thicker, stickier sweat made of proteins and lipids is produced by the apocrine, which is primarily found in and around your armpits and genitalia. Your entire body is covered in eccrine, which creates a main water and salt solution. The eccrine glands were once thought to be activated simply by a need for cooling, while the apocrine were thought to be activated by mental stress.

What is the significance of farmers learing how to use these
technologies and integrating them into the decisions they make on a daily basis for growing crops and raising animals?
Farmers need to adapt precision agriculture to increase the crop yield, productivity and bring the expenses in control.
For every farmer, agricultural retailer, and agronomist, technology has evolved into a necessary component of conducting business. No one should be shocked by the high rate of technological use in agriculture. Farming requires a lot of land and effort. Farmers are compelled to employ technology to boost productivity and control expenses.
Precision farming and precision ag are other terms for precision agriculture. The best approach to grasp precision agriculture may be to see it as anything that makes farming more precise and regulated when it comes to producing animals and growing crops.
The utilization of information technology and a variety of tools, including GPS guidance, robots, control systems, drones, sensors, telecommunications, autonomous vehicles, GPS-based soil sampling, variable rate technology, automated hardware, and software, is a crucial aspect of this farm management strategy.
Another crucial phrase associated with the fusing of approach and technology is "precision agronomics." It primarily focuses on offering more precise farming methods for planting and cultivating crops.

If animals are fed a high-protein diet, then it will not cause them to build muscle.
High-protein diets are not healthy for animals.
High-protein foods are important for building muscles. So, if animals are fed a high protein diet, then this will not cause them to build muscles. Thus option C is correct.
What is a high-protein diet?A high-protein diet is a diet in which 20% or more of the daily calorie intake comes from protein. A high-protein diet helps increasing the muscular mass.

Which of the following is likely to describe a metabolic reaction where the net delta G value is positive?
spontaneous or non-spontaneous
catabolic or anabolic
positive delta E or negative delta E
The non spontaneous, anabolic and positive delta E are some of the reaction where net delta G is positive.
What are metabolic reactions?The Gibbs free energy difference between a reaction's products and reactants is known as delta G.
The response is spontaneous if Delta G is negative, non-spontaneous if it is positive, equilibrium if it is zero, and non-spontaneous if it is negative. If dH is positive and dS is negative according to the equation dG = dH - dS*T, then delta G is positive.
Delta G is negative if dH is negative and dS is positive. It depends on the temperature at which the reaction is taking place whether dH and dS are both positive or both negative.
