Answer: The answer is the layer of the sun that radiates energy outwards from the sun core

Explanation: the reason why that is becuase the convection zone is a layers which is unstable to convection. And energy is primarily or partially transported by convection

The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.

It is the central star of our solar system around which the planets and other planetary bodies revolve. Ninety-nine per cent of the mass of the entire solar system is constituted by the sun.

The sun produces a tremendous amount of energy. A part of this energy reaches the earth. The perfect distance of the earth from the sun ensures that this energy supports life on earth.

The sun is considered to be a 'dwarf' star among the other stars studied and observed in the observable universe. The sun has been formed from the material which had been processed inside of a supernova and is present in the outer regions of our milky way galaxy. The sun is made of several layers and each has its own role.

Therefore, The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.

Answer:if youre talking only about frogs and pigeons then.....a frog has four limbs.

a pigeon walks on 2 legs

Explanation: the frog has 2 limbs at the back and 2 on the front....

a pigeon walks with its two tiny legs

shared derivation is that they both lay eggs

The frog has 2 limbs at the back and 2 on the front. a pigeon walks with its two tiny legs.

A cladogram is a representation of a potential link between groupings of species, including their shared ancestors. The Greek terms "clados" and "gramma," which mean "branch" and "character," respectively, are the origin of the words "cladogram."

The image gives the impression that a tree trunk is sprouting branches. Yet, the cladogram's form is not necessarily vertical. The diagram's sides, top, bottom, and center can all branch off of it.

Cladograms can be exceedingly complicated, potentially classifying all forms of life, or very simple, comparing only a few types of organisms.

xylem vessels carry water and dissolved materials from the roots to the rest of the plant

Answer:

Current

Ampere is the unit for current.

The ammeter which is connected to an electric circuit shows us that there are 5 amperes (A) of electric current in the circuit. Ammeter is a device used to measure current.

An ammeter is an instrument which is used to measure the electric current which can be either direct current (DC) or alternating current (AC) electric current, in units of amperes (A). Ampere (A) is the SI unit of electric current.

An ammeter can measure a wide range of electric current values as at very high values only a small portion of the electric current is directed through the instrument and a shunt is placed in parallel arrangement with the meter which carries the major portion of the circuit.

Answer:

Explanation:

Answer:

Here is the answer key. Just scroll down to the question and the answer is there.

Explanation:

These organisms are still alive. Reproduction is not important for survival but for the survival of a species.

The only way to ensure that the kind of species survives and keeps flourishing on the planet is through reproduction. The process by which organisms give rise to new offspring is called reproduction. It is one of the many defining characteristics of life and loving organisms.

There are some organisms that look and act exactly like their parent/parents. Whereas, other kinds of organisms share similar traits with their parents but are not completely like them. These organisms are unique individuals in their various characteristics.

Some species have two parents, whereas others have just one. It is determined by the method of reproduction by these organisms. It also determines the percent of similarity of the organism with its parents.

Reproduction is basically of two types: asexual reproduction and sexual reproduction. Asexual reproduction involves the development of new organisms by a single parent. Sexual reproduction involves two parents and their fusion of gametes.

Therefore, Reproduction is essential for the survival of a species and not for the survival of an organism.
