Answer is A. A Hox gene

Hox genes are a series of genes that controls the differentiation of cells and tissues in an embryo by turn on and off other genes. If Hox genes express incorrectly, a major changes in the morphology of the individual can be seen.

Let’s understand this with an example: The Ultrabithorax, a Hox gene determines the Third thoracic segment in <em>Drosophila melanogaster</em>. Third thoracic segment displays a pair of legs and a pair of reduced wings used for balancing. In the mutant<em> Drosophila</em> the functional Ultrabithorax protein is absent. Due to this mutation, the third thoracic segment now expresses the same structures found on the second thoracic segment, which contains a pair of legs and a pair of wings which are fully developed .

If an area is in the 50+ dBZ range, what atmospheric pressure conditions could the area be experiencing?
monitta

The atmospheric pressure conditions for a 50+ dBZ range differs from small to heavy hails.

Explanation:

dBZ refers to decibel relative to Z used in weather radar most of the times, in order to compare the reflection factor (Z) of a weather radar signal reflected off a remote object  to the return of a droplet of rain with a diameter of 1 mm.

dBZ is a logarithmic dimensionless technical unit, at 55 dBZ and above, most storms have hail which can throw off the rainfall rate because hail has a higher reflection.

Generally above 50 dBZ range the intensity varies accordingly for every 5 points. Such as small hail to moderate hail and from moderate to heavy hail.

Therefore the atmospheric pressure conditions differs from rains to hails.

Can you sequence the steps in the eutrophication process that occurs in a body of water Part A Drag each statement to the approp
Ugo [173]

Answer:

The first cause of eutrophication is the increase level of nutrients in water.

Explanation:

Then the other effect follow:

1.- Nutrients promote more phytoplanckton at the surface of the body water.

2.- phytoplancton die and settle down at the bottom.

3.- since in the bottom there is no much more sun, the algae at the bottom start to die, plus the phytoplacton that is falling, the sediment at the bottom start to grow.

4.- Since there is any living thing that can produces oxygen in water( it produces hypoxic conditions), other living things start to die.

using the equation cs2+3o2=co2+2so2 what is the percent yield of so2 if the burning of 12.5g of cs2 produces 15.12 g of SO2
vesna_86 [32]
<h3><u>Answer;</u></h3>

  = 71.96%

<h3><u>Explanation</u>;</h3>

1 mole of CS2 = 76.133 g

1 mole of SO2 = 64.06 g

1 mole of CS2 reacts with 3 moles of Oxygen to produce 2 moles of SO2

Moles of CS2 in 12.5 g = 12.5/76.133

                                      =  0.164 moles

Mass of SO2 = 0.164 mol × 2 × 64.06

                      = 21.01168 g

Therefore;

Percentage yield of SO2

  = 15.12/21.01168 × 100%

<u>   = 71.96%</u>
