14) You are studying the rose-spotted numbat, which lives for one year. In this species there are two types of helpers. Type I h

elpers repel predators, bring food to the young and defend the territory. Having one of these helpers increases the reproductive output of the breeders by 0.5 offspring. Type I helpers are related to the young of the breeding pair by r-0.4, on average. Additionally, the Type I helpers can occasionally breed and produce, on average, 0.5 offspring per year. Type II helpers do not breed, however, they are much more effective in providing help to the breeders. Their help, which is also given exclusively to the breeders (to whose young they are also related by r 0.4) results in an increase of 1.5 offspring. Which of the following statements is true? a) Type II helpers have greater direct fitness than Type I helpers b) Type II helpers have greater inclusive fitness than Type I helpers c) Breeders with Type I helpers have higher fitness than breeders with Type II helpers d) Type I helpers have greater indirect fitness than Type II helpers e) Type I helpers do not increase the fitness of the breeders they help

⭐Hola User_______________

⭐Here is Your Answer...!!

_______________________

↪Actually welcome to the concept of the Mode of tranfer of heat in solids and fluids

↪Basically here referring to the medium of transfer of heat

↪Soil = Solid medium and water = liquid medium

↪Basically according to the theory of thermal conductance. .

↪Solids transfer heat through conduction and liquids through the convection , thus here

↪The particlas in solid are more close and have much higher force of attraction in moleclues than the liquids , thus CONDUCTION occurs faster than CONVECTION..

↪therfore the soil will cool faster than the water ...

<span> D.all of the above

Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function. A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host. The two organelles also reproduce like bacteria, replicating their own DNA and directing their own division.
