explain why a slow growing forest can have a very low npp and yet store a massive amount of biomass (have a high standing crop).
Slow-growing forests can have a low net primary production (NPP) yet store a large amount of biomass because of their slow growth rate.
This is due to the fact that slower-growing forests have a higher likelihood of accumulating biomass over a longer period of time since less biomass is lost to breakdown and other processes.
Although carbon is released into the atmosphere more slowly in slow-growing forests, there is a tendency for these forests to have larger carbon concentrations in their biomass.
Because of this, forests can store more biomass even when their rates of growth and photosynthesis are low.
As for their higher biomass and carbon storage, slow-growing forests also tend to be more resistant to disturbances like wildfires or insect infestations. As a result, despite having a low NPP, they may store a lot of biomass.

______ psychology is especially interested the biological and environmental factors in how people change as they age
Developmental psychology is especially interested the biological and environmental factors in how people change as they age.
The scientific study of how individuals change and evolve throughout their lives, from birth to old age, is known as developmental psychology. One of the primary aims of developmental psychology is to comprehend the biological and environmental processes that contribute to these changes.
Biological influences include heredity, brain development, and hormone changes, all of which can influence a person's growth. Environmental influences include familial ties, culture, education, and social contacts, all of which can have an impact on a person's growth.
Developmental psychologists study how these elements interact and impact one another through time, and how they might result in the vast diversity of human behaviours, emotions, and cognitive capacities seen across the lifetime. Developmental psychologists examine these processes in order to uncover patterns of development and to create theories and interventions that can assist promote healthy development and well-being.

which are used to keep our systems at or near their setpoints
The feedback loops whether positive or negative are used to keep the systems at or near their setpoints.
While, the feedback loops are typically divided into two categories:
1) Positive feedback loops: As one thing changes, another thing also changes, and so on.
For instance, as a substance's concentration rises, a feedback loop results in further concentration rises.
2) Negative feedback loops, where a change in one direction results in a change in the other.
For instance, an increase in a substance's concentration can result in feedback, which eventually leads the substance's concentration to drop.
Most of the systems with positive feedback loops are by simply nature unstable. The Positive feedback loops can sometimes result in runaway conditions because a change in an input prompts responses that keep changing in the same direction. When a variable is present, the term "positive feedback" is often employed.

how the passive transport low to high
Passive transport occurs when substances move from a high concentration region to a low concentration area through a process known as diffusion.
A concentration gradient is a physical space in which the concentration of a particular substance varies. Active transport is the movement of molecules across a cell membrane in the opposite way of their concentration gradient, from low to high concentration.
Substances move against the concentration gradient during active transport, from a low concentration region to a high concentration area. This procedure is considered "active" because it necessitates the use of energy (usually in the form of ATP). It is the polar antithesis of passive transportation.

which process provides the main force driving water within xylem vessels?
Water in the xylem travels toward the top primarily due to evaporation due to the tension produced by transpiration pull.
Water in the plant's xylem is forced upward by the tension produced by transpiration, much like how tugging on a straw causes water to rise.
Cohesion leads to more water molecules filling up the available space in the xylem as the uppermost water is drawn toward the stomata. The water eventually leaves the plant through the stomata and enters the atmosphere as vapor.
On the surfaces of leaves, stomata are tiny, completely contained pores. In general, transpiration involves the absorption of water by the roots, the movement of water through plant tissues, and the exhalation of vapor by leaves.
Evaporation is the primary mechanism by which water in the xylem flows at the top because transpiration pulls the water and plants evaporate water.

what is true of mobile electron carriers
The mobile electron carriers are ferry electrons between one respiratory complex and the next. So, the correct choice is option(d).
The electron transport chain (ETC), which functions in the mitochondrial membrane, consists of four protein complexes and two mobile electron carriers. Mobile electron carriers are small proteins or hydrophobic molecules that make up the respiratory chain. Electron carriers play a central role in many biological processes, including cellular respiration. During cellular respiration, electrons from glucose molecules are captured by electron carriers. After going through several steps, glucose is broken down and energy is gradually produced through the electron transport chain. Thus, a molecule can accept one electron from another molecule (electron donor) and in the process of electron transfer can carry electrons to donate to another molecule. NAD⁺ (Nicotinamide adenine dinucleotide) is an example of an electron carrier. So option (d) is the correct answer.

what is the difference between voluntary and involuntary control of muscles?
voluntary muscle control is conscious control of skeletal muscles, while involuntary muscle control is the automatic regulation of smooth muscles, cardiac muscles, and glands.
The human body has two types of muscle control: voluntary and involuntary. Voluntary muscle control refers to the ability to consciously control the movement of skeletal muscles, which are attached to the bones and responsible for locomotion and other bodily movements. Involuntary muscle control, on the other hand, refers to the automatic or reflexive control of smooth muscles, cardiac muscles, and glands.
Voluntary control of muscles is initiated by the central nervous system, which sends signals from the brain to the muscles through the motor neurons. This type of muscle control is under conscious control, meaning that the individual can decide when and how to move their muscles.

Adenine, thymine, cytosine, and guanine are the four nitrogenous bases that may be found in DNA. Adenine and thymine always bond together, while cytosine always binds to guanine. As certain bases are always found in pairs, they will make up an equal proportion of the DNA.
DNA always includes equal quantities of guanine and cytosine as well as adenine and thymine, according to Chargaff's analysis of the four distinct base molecule proportions in the late 1940s.
