Throughout the lifespan, we change physically, cognitively, and psychosocially. This illustrates the notion that development is
gayaneshka [121]

Answer:

multidimensional

Explanation:

Development is multidimensional

By multidimensionality, we mean a complex and dynamic interaction of factors that control development all through the lifespan, it as to do it biological, cognitive, and socioemotional changes.

Let's take for instance, in adolescence, puberty comprises of physiological and physical variations with variations in hormone levels, the formation of primary and secondary sex characteristics, changes in height and weight, and varying other bodily alterations. The cognitive changes (increment in thinking- abstractly), emotional and social changes (controlling emotions and relationships with equals, falling in love).

Puberty deals with a wide range of domains that exemplifies the multidimensionality component of development.

Which of the following promotes closure of the minivalves associated with lymph capillaries?
Molodets [167]

Answer:

increasing pressure inside the lymph capillary

Explanation:

Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.

The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.

The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.

When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.

Thus, the selected option is the correct answer.

Neurotransmitters can affect postsynaptic cells by I) initiating signal transduction pathways in the cells II) causing molecular
Yakvenalex [24]

Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.

The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.

When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.
