Answer:

Water, carbon, and nitrogen

Explanation:

There are numerous cycles of matter in the natural world, but three of them play very significant roles in ecosystems: the water cycle, the carbon cycle, and the nitrogen cycle.

Each cycle serves its own purpose. The water cycle is the process by which water falls to the earth's surface, is used up by humans and other living organisms, and is brought back up into the air by evaporation/transpiration. The carbon cycle is the process by which carbon is produced by factories and/or living organisms and then used up in other systems that help organisms survive. And, finally, the nitrogen cycle is the process by which nitrogen circulates throughout the ecosystem, from the atmosphere to nitrogen-fixing bacteria in the soil to plants and organisms and back into the atmosphere.

Hope this helps!

In cats, the gene for Calico (multicolored) cats is an x-linked trait that is
hichkok12 [17]

Answer:

Considering the <u>whole progeny</u> (100%), there will be

  • 25% Black male kittens, XBY
  • 0% Calico Male kittens
  • 25% Calico female kittens, XBXR

Explanation:

<u>Available data:</u>

  • The gene for Calico (multicolored) cats is an x-linked trait and codominant
  • Calico Females receive a "B" and an "R" gene, and have black and orange splotches on white coats. Their genotype is XBXR.
  • Males can only be black or orange, but never calico. Their genotype is XBY and XRY

Cross: a female calico cat with a black male

Parentals)   XBXR    x    XBY

Gametes)  XB  XR       XB   Y

Punnett square)    XB        XR

                   XB   XBXB   XBXR

                    Y      XBY      XRY  

F1) Among the whole progeny:

  •     2/4 = 50%  will be black (female XBXB and male XBY)
  •     1/4  = 25% will be Calico (female XBXR)
  •     1/4  = 25% will be Orange (male XRY)  

   Among females:

  •    1/2 = 50% of females will be black, XBXB
  •    1/2 = 50% of females will be Calico, XBXR

   Among males:

  •    1/2 = 50% of males will be black, XBY
  •    1/2 = 50% of males will be orange, XRY

A piece of metal has a mass of 10 g in a volume of 2 cm to the exponent of three what is the
rewona [7]

Answer:

5g/cm³

Explanation:

Given parameters:

Mass of the metal  = 10g

Volume of the metal  = 2cm³

Unknown:

Density of the metal = ?

Solution:

Density is the mass per unit volume of a substance.

Mathematically;

      Density  = \frac{mass}{volume}  

 Insert the parameters and solve;

      Density  = \frac{10}{2}   = 5g/cm³

“blank” investigations are best for demonstrating cause-and-effect relationships. a. descriptive b.comparative c. experimental
FromTheMoon [43]

C. Experimental

Explanation - The cause and effect of a process would be studied in experimental investigations. However, in descriptive studies, relationship between the factors are not studies rather the detail of the process is studied. In comparative investigation, several factors are compared and its effects are analyzed.

In experimental investigations, experiments are carried out based on the hypothesis and then it is validated accordingly. Validation is a must to prove and disprove the hypothesis. Therefore, experimental data and hypothesis are related.
