Consider the phylogeny below. The coelom evolved once in the common ancestor of protostomes and deuterostomes. What does the phy
VikaD [51]

Answer:

Flat worms belong to Phylum- Platyhelminthes as they have flat body because they don't have any coelom in their body or called acoelomate

Explanation:

Coelom is called as the true body cavity that is found in Porifera and Cnidaria but when it comes to platyhelminthes, the coelom is not found and thus they have flat like structure and they are categorized under first triploblastic  animals that is they contain 3 tissue layer which are found in higher animals (Ectoderm, Mesoderm and endoderm) also cephalization takes place in this parasitic group which indicates evolution towards higher, complex organisms.

HELPPPPPP QUICK please!
denpristay [2]

HI~ I hope this helps

(these answers were hand-written meaning I did not copy and paste so, feel free to use the answers freely)

1.

When ecosystems change rapidly the fundamental environmental cycles such as the circulation of water, carbon and nutrients can change as ecosystems depend on them. The usage of factors such as freshwater, carbon dioxide emissions and fertilizer provides a large benefit to humas therefore meaning, that large and rapid changes to an ecosystem could also effect the things we as humans rely on.

2.  

Complex organic matter is broken down by decomposers into carbon dioxide, water etc. The ecosystem is affected based upon the fact that the decomposition of organic matter that is produced by plants, animals and soil organisms is an important process which affects the different important ecosystem processes like nutrient cycling and carbon sequestration.

3. (could have two answers- I recommend the second)

Adaptation- due to the mutation process which results in changes in the structure and function of organisms, these ecosystems would be different as well as unique. The organisms which possesses the traits needed to adapt could then survive as its unique characteristics due to mutation would provide a strong ability

Rise in temperature- If the temperature located on earth was to rise, organisms would have a higher living rate as bacterial life flourishes in warmer temperatures and dies out in colder ones.

4.

~The rapid change of increased food production provides better life sustainability to those living in the ecosystem.

~The rapid change in a large increasing number of organisms could be helpful as they often live of off one another.

5.

~Rapid growth of things such as phytoplankton which cause dead zones are harmful to the ecosystem. Dead zones create zones where too much oxygen is consumed resulting in areas where plants and sea life can no longer survive.

~Whereas the rapid increase of organisms could also be harmful to an ecosystem as the possibility of the organism outnumbering the food sources could become prominent.

A marine biologist took two true breeding fish, one orange with stripes, and one white with spots, and crossed them. All of the
fiasKO [112]

Yes! We can see which are dominant!

In this first generation progeny, we see that stripes are dominant and spots are recessive. And white bodies are dominant over orange!

I am a bit rusty on genetics, but I believe I am correct

Diferença entre soluções líquidas e líquidos puros
vladimir1956 [14]

Portuguese version:

Não falo português mas:

Uma solução é formada quando algo é adicionado ou dissolvido em um líquido. Você faz uma solução quando adiciona sal ou açúcar a um copo de água. ... Desde que um líquido seja feito de uma única substância, ele permanece puro e é chamado de líquido. Quando algo é adicionado a ele, ele se torna uma solução.

English version: I don't speak Portuguese but:

A solution is formed when something is added or dissolved in a liquid. You make a solution when you add salt or sugar to a glass of water. ... As long as a liquid is made of a single substance, it remains pure and is called a liquid. When something is added to it, it becomes a solution.

Spanish version: No hablo portugues pero:

Se forma una solución cuando algo se agrega o se disuelve en un líquido. Usted hace una solución cuando agrega sal o azúcar a un vaso de agua. ... Mientras un líquido esté hecho de una sola sustancia, permanece puro y se llama líquido. Cuando se le agrega algo, se convierte en una solución.

fReNcH vErSiOn: Je ne parle pas portugais mais:

Une solution se forme lorsque quelque chose est ajouté ou dissous dans un liquide. Vous faites une solution lorsque vous ajoutez du sel ou du sucre à un verre d'eau. ... Tant qu'un liquide est constitué d'une seule substance, il reste pur et s'appelle un liquide. Quand quelque chose y est ajouté, cela devient une solution.

Ok, terminei, tchau.

Okay, I'm done, Bye.

Bien, he terminado, adiós.

D'accord, j'ai fini, au revoir.

You have adopted a gray mouse, which you know is a wild type phenotype. When crossed with a white mouse, your gray mouse has a f
sashaice [31]
Assuming the white phenotype is recessive. white: gg
I think the gray mouse is Gg because the offspring were pretty equally distributed in terms of color. See the punnet square below.
g g
G| Gg Gg
g| gg gg

If the Gray phenotype is recessive, then gray: ww but only if white is Ww because its about 50% chance for both.
