Which kingdom or supergroup is characterized by organisms that are heterotrophic by ingestion?
Akimi4 [234]
The kingdom described above is the kingdom Animalia. Heterotrophic mode of nutrition is a type of nutrition in which organisms depends upon other organisms such as plants for survival, for example all animals are heterotrophic and obtain all organic materials they need to survive. The other type of nutrition is the autotrophic mode of nutrition in which organisms use simple inorganic substances to synthesize organic molecules, a characteristic of plants.

1. The right answer is AC (alternative current) generators.

AC current (which can be abbreviated as AC) is a periodic electrical current that changes direction twice per period and carries alternating amounts of electricity in one direction and the other1. An alternating current therefore has a continuous component (average value) zero.


2. The right answer is Repel, and attract.

The nucleus of an atom is an assembly of protons and neutrons concentrated in a very small volume and subjected to two different forces: the nuclear force and the electric force.

The electric force only acts on charged particles, attracting those which are of opposite signs and repelling those of the same sign. This "long" distance force allows the negatively charged electrons to be retained around the positively charged nucleus.


3. The right answer is electric circuit

An electrical circuit in the material sense is a simple or complex set of electrical or electronic components, including simple conductors, traversed by an electric current.

In the sense of circuit theory, an electrical circuit is an abstraction of material configurations, an arrangement of elements defined by mathematical relations, connected by ideal conductors.


4. The right answer is Volts and current.

Volt (V) is the unit of measurement of the electrical voltage in a circuit between a point A and a point B, obtained with a device called a voltmeter. It is to Alessandro Volta, Italian physicist and inventor of the electric battery, that we owe this name.

The ampere (A) is the unit of measurement of the intensity of an electric current, that is to say the flow of electrons in a conductor. André-Marie Ampère, the inventor of the electromagnet, gave his name to this unit.


5. The right answer is north pole.

The magnetic North Pole of the Earth is a unique wandering point on the surface where the Earth's magnetic field is pointing down. That is, the "dip"  is 90 °. The needle of a compass points approximately towards this place (more or less approximately according to the place where one is, exactly the compass is tangent to the line of field).


6. The right answer is perpendicular.

In a cyclotron, the magnetic field is applied perpendicularly in an empty disk-shaped chamber, which contains two D-shaped semicircular electrodes. The rectilinear portions of these electrodes face each other. The flow of electrons or ions crossing a perpendicular magnetic field is subjected to a forceperpendicular to the direction of movement.


7. The right answer is current

A solenoid is a device consisting of an electric wire wound regularly in a spiral so as to form a long coil. Running through a current, the solenoid produces a magnetic field in its vicinity, and more particularly inside the helix where this field is almost uniform.

The __________ perspective on the family is characterized by concepts linking psychosocial factors to physiology, genetics, and
Neko [114]

Answer:

The correct answer is -Biosocial perspective.

Explanation:

In the last few years, the research and thinking on biosocial perspectives on the family come in light. The biosocial perspective on the family is characterized by concepts or laws related to various psychological factors to evolution, genetics, and physiology.

Three major developments that are contributed in this perspective are findings of proximate biological interplay, advances in evolutionary thinking and alteration in the field of studies related t the family.

Thus, the correct answer is - the biosocial perspective.

Will give brainliest plz help I only need help with the 2nd question
Akimi4 [234]

Answer:

Secondary Consumers

Explanation:

If the larvae eat the needles, they are the primary consumers and herbivores. Because they eat the larvae, the birds become the secondary consumer. Tertiary consumers are at the top of the food chain, and eat secondary consumers and primary consumers. Primary producers are energy producing things like plants, etc.
