Sea corals live exclusively in the ocean and are radially symmetrical. They have microscopic stinging barbs that shoot out to immobilize their prey. This allows corals to hunt even while they are stuck to the ocean floor.

What animal phylum do corals belong in?

chordates
mollusks
cnidarians
annelids

Answers

Answer:

phylum Cnidaria

Corals, anemones and jellies are related and all classified in the phylum Cnidaria or “stinging needles.” The animals in this group are aquatic, possess stinging cells within their tissues and have a body plan characterized by radial symmetry, which allows all parts of their bodies to be equally receptive and ...

What are the three layers that make up the body of a Cnidarian?

A. endoderm, mesoderm, ectoderm
B. endoderm, mesoglea, ectoderm
C. ectoderm, mesoderm, mesoglea
D. endoderm, mesoglea, epidermis

Answers

The endoderm is the inner layer ('endo' for 'within'), and the ectoderm is the outer layer ('ecto' for 'outer'). If there was a third layer it would be called the mesoderm, 'meso' for 'middle'. But cnidarians do not have this middle layer. Germ layers develop during gastrulation.

took the test

3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?

Answers

It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.

In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.

An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.

In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.

A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.

A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).

In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

A single base substitution mutation is likely to have a less deleterious effect when the base change exhibits which of the following results

Answers

A single base substitution mutation will be the least likely to cause a deleterious effect when the base change produces the same amino acid as the original.

What is a silent mutation?This scenario is what we call a silent mutation. What this means is that the mutation is almost undetectable due to its not affecting the protein that it will help to form.This is possible thanks to how the genetic code operates, different codons are able to code for the same amino acid.Therefore, there are mutations that do not affect the amino acid or the protein.

Therefore, we can confirm that a mutation will have no negative effects if it is a silent mutation, meaning that the substitution of a base pair happens to code for the same amino acid as the original.

some scientists predict that if global warming continues over the next few centuries, melting of the polar ice caps will rise the level of the oceans causing some peninsulas to become islands. how might this change eventually affect the species that live on these peninsulas?

Answers

Answer:

As global warming causes more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth's surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere.

Zach Corp. pays commissions to its sales staff at the rate of 3% of net sales. Sales staff are not paid salaries but are given monthly advances of $15,000. Advances are charged to commission expense, and reconciliations against commissions are prepared quarterly. Net sales for the year ended March 31 were $15,000,000. The unadjusted balance in the commissions expense account on March 31 was $400,000. March advances were paid on April 3. In its income statement for the year ended March 31, what amount should Zach report as commission expense?

Answers

Based on the information given the amount that Zach should  report as commission expense is $450,000.

Using this formula

Commission expense=Percentage of net sales× Net sales

Where:

Percentage of net sales=3%

Net sales=$15,000,000

Let plug in the formula

Commission expense=3%×$15,000,000

Commission expense=$450,000

Inconclusion the amount that Zach should  report as commission expense is $450,000.

describe why rocks found at the bottom of the river are smooth and flat.Please in your own words,My teacher would get mad

Answers

The rocks found at the bottom of a river smooth and flat because those are collides with each other.

Explanation:

At the bottom of the river, the rocks which are found are very smooth and the shape of these rocks are flat because the rocks at the bottom collide with each other.

This results in the chipping off parts of the rocks and this results in the surface of the rock to become smooth and becoming flat. Moreover the sand found at the bottom acts as a sand paper creating resistance and smooth-ens the rocks at the bottom of the river.

Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.

What is Abrasion?

Abrasion is the process of rubbing or scraping away a material, by rubbing against a rough surface or causing friction. This type of mechanical weathering can be brought about by a variety of things, including wind, water, snow, and human action. Rock, metal, plastic and wood are some of the materials that may be subject to abrasion.

This may result in material loss and modification of the appearance and texture of the surface. Natural features such as the smoothness of river boulders or the roundness of pebbles on a beach can also be the result of friction. Sandblasting, grinding and polishing are some examples of industrial abrasive applications.

Therefore, Abrasion, which is the physical wearing away of a material by friction, is the process that results in the formation of smooth and flat rocks often found at the bottom of rivers.
