Answer:  a. to decompose dead animals

Explanation:

Detritivores are the hetrotrophic organisms which feed upon detritus (dead and decaying plant and animal matter). These detritivores break down the biological dead matter into simple molecules which are readily consumed by the small microorganisms present in the soil. Detritivores are essential for the ecosystem as they return important materials such as carbon and other essential elements back to the environment after decomposing the dead matter. Example of common detritivores includes earthworms.

On the basis of the above explanation, the role of a detritivore is a. to decompose dead animals.

The role of a Detrivore is to help recycle the nutrients in the soil. They break down complex proteins, and other materials so the answer is A. to decompose dead animals.

Anuta_ua [19.1K]

The question is incomplete. Here is the complete question.

In horses, the Overo gene, <em>Ov</em>, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, <em>Ovov</em>. Horses with two <em>Ov</em> copies, <em>OvOv</em>, die soon after birth are called white overo because they are completely white. Horses with no <em>Ov </em>copies are solid colored, <em>ovov</em>.

The Leopard complex gene, <em>Lp</em>, shows incomplete dominance and controls white spotting. One <em>Lp </em>allele, <em>Lplp</em>, produces the leopard phenotype, in which there are spots everywhere. Two <em>Lp</em> alleles, <em>LpLp</em>, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from <em>Lp</em> is indistinguishable from the white from <em>Ov</em>.

Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.

overo:

white overo:

fewspot:

Answer: Overo: 2

              White overo: 0

              Fewspot: 3

Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.

To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:

Punnett Square For overo and white overo:

          Ov             ov

Ov    OvOv        Ovov

ov    Ovov          ovov

Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.

Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.

Punnett Square For leopard and fewspot:

          Lp         lp

Lp    LpLp      Lplp

lp     Lplp       lplp

From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo <u>and</u> fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.

Peter consumes no commodities other than miller lite and bud light. his annual budget for these two commodities is described by
liq [111]

The answer Peter will consume 60 sixpacks of Miller lite per year.


The solution for this problem is:


The cost of 6 Miller six packs is 5 * 6 = 30.


Then the cost of 2 Bud cases is 30 * 2 = 60.


Consequently, Miller is low-priced so Peter will buy as much Miller as possible.  Therefore, <span><span>300 which is the budget divided by 5 is the cost for the Miller sixpacks = 60</span></span>

The rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)? The rapid depola
fgiga [73]

Answer:

Na+ only

Explanation:

Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.

This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.

In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.

Thus, Na+ only is correct.

Why do dinoflagellates thrive in bahia fosforescente
lukranit [14]
<h2>Dinoflagellates thrive in bahia fosforescente</h2>

Explanation:

  • Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
  • It has a characteristics of both plants and animals.
  • Most of the dinoflagellates are marine, but some live in freshwater habitats.
  • Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
  • Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
  • During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
  • Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.
