In most animals, the ______ state of the life cycle is much larger than the ______ state.

frozen [14]

In most animals, the <u>diploid</u> state of the life cycle is much larger than the <u>haploid</u> state.

The multicellular diploid stage is the most evident life stage in a diploid-dominant life cycle, and the only haploid cells are the gametes. Most animals, including humans, have this kind of life cycle. It is much larger than the haploid life cycle because of the complexity due to diploid stages.

The multicellular (or occasionally unicellular) haploid stage is the most visible life stage and is frequently multicellular in a haploid-dominant life cycle. The only diploid cell in this kind of life cycle is the single-celled zygote. This kind of life cycle is found in some algae and fungi.

Meiosis, which produces haploid cells from diploid ones in all sexually reproducing species, and fertilisation are two examples of fundamental life cycle characteristics that all sexually reproducing species share (the fusion of haploid gametes to form a diploid cell called the zygote).

Angelina_Jolie [31]

Complete question:

This Roman snail, this cuttlefish, and this mussel have similarities and

differences in their body structures. What does the information about these

structures tell you about the ancestors of these species?

a) None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.

b) The Roman snail and the cuttlefish share an ancestor population, but they must not share an ancestor with mussels because mussels have no radula.

c) All three species share an ancestor population, but Roman snails and

cuttlefish share a more recent ancestor population. This is why they share

the radula structure.

d) We cannot make observations of ancestor populations from the past. It is

impossible to explain ancestors with only the information about the body

structures of different species.

Answer:

The correct answer is option C. All three species share an ancestor population, but Roman snails and cuttlefish share a more recent ancestor population. This is why they share the radula structure.

Explanation:

The three species belong to the mollusk phylum, and to the placophore group.

Each of them belongs to a different class.

The Roman snail belongs to the Gasteropod class,
The cuttlefish belongs to the Cephalopod class,
The mussel belongs to the Bivalve class.

The tree classes share a common ancestor from which all the placophores evolved. Among them, we can mention the monoplacophore, gasteropod, cephalopod, bivalve, and scaphopods. Three branches diverged from this common ancestor. The first one originated the monoplacophore. The second one originated the common ancestor of gastropods and cephalopods. And the third one originated the common ancestor of bivalves and scaphopods. The tree-mentioned species inherited the mantle and the radula from their foreign common ancestor. But later in time, individuals that originated bivalves lost the radulla. This is why the three species have a mantle, but only gastropods and cephalopods have a radula. When each of these classes evolved, they developed their own traits,

Gastropods → muscular foot used for moving
Cephalopods → pallial cavity for swimming
Bivalves → byssal threads to attach to the rocks

I'LL GIVE BRAINLEST!

Y_Kistochka [10]

Answer:

Ok so i will try my best to describe the answers:

1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.

2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.

I hope this helps :D

Why is bioremediation a preferred method for cleaning up the environment?

finlep [7]

It is a natural acceptable fast process of cleaning contaminated materials in the environment. It is cost effective in cleaning hazardous wastes compared to other methods.This method can easily be done without disrupting normal activities. Residues for this kind of treatment are usually harmless products.
