Camel humps are an adaptation for _______.. a.. storing water. b.. regulating body heat. c.. carrying riders. d.. all of the abo

Fofino [41]

The correct answer is:

b regulating body heat.

Explanation:

Camels have humps on their backs as rooms to store fat. It is this fact that they live off when food and liquid are scarce. A well-fed camel in good shape has a firm, upright hump. After a long, exhausting wilderness journey the corresponding camel will have a hump that does floppy and bent over to one side.e. Concentrating body fat in their humps reduces heat-trapping.

Natali5045456 [20]

It is C as to have freckles you have to have a dominant and recessive gene (can be worked out using a punnett square) as the child has 50% of not having freckles like his dad or 50% having freckles like his mom.
male genes(homozygous recessive)
f f

female F Ff Ff
genes
f ff ff

so ff is not having freckles and being homozygous recessive, or Ff having freckles and being heterozygous.

So the child is heterozygous so C

The growth of a population of sparrows accelerates with each generation. the chances of dying are about the same for these sparr

Paladinen [302]

Answer:

Exponential growth and a type II survivorship curve

Explanation:

Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.

Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.

In Type II survivorship curve, there is a constant dying rate of individuals of population with respect to time.

Now lets come back towards question, where two characteristics of the population are mentioned,

Exponential growth of a population of sparrows with each generation.
Constant dying rate

This clarifies that Exponential growth and a type II survivorship curve is the best option representing the said scenario.

Hope it help!
