There are three stages of the dragonfly life cycle, the egg, the nymph, and the adult dragonfly. Most of the life cycle of a dragonfly is lived out in the nymph stage
Life as an Aquatic Larva
Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. After the egg hatches, the free-crawling aquatic larva molts once and then starts hunting voraciously. As the larva grows, it will molt numerous times. Most dragonfly larvae mature to adulthood in one to three years. so maybe *(c.)

What was the carbon cycle on the prairie like?
Answer:
It stores more carbon below ground than a forest stores above.
Explanation:
Answer:
prairie plants
Explanation:
Roots of prairie plants are developed through centuries of growth. These deep roots will take the carbon out of the air add nutrients to the soil when they die, contributing to rich soil.
Prairie plants are especially adept at storing carbon, locking up large amounts in their roots. In fact, prairies store more carbon below ground than a forest stores above! Deep, complex prairie root systems sequester (store) carbon and – with the help of microorganisms – move it to the soil where it stabilizes.

The theory of evolution states the change in the traits to adapt and survive the altered conditions. Offsprings, artificial selection, natural selection, diversity and adaptation are the correct blanks.
What is natural and artificial selection?Animals or the species of the organism breed and reproduce to produce offspring or the progenies that continues the lineage of the specific species.
Artificial selection is the process of choosing the animals that have better characteristics over another and is done by humans. It is done in order to select the genetically variable species.
Charles Darwin gave the theory of evolution based on the mechanism of natural selection that states that nature chooses the fit and animals with better traits and qualities that can adapt to the change and continue to reproduce.
During his voyage of the Galapagos island, Darwin discovered the diversity of the bird and tortoise species of the same kind but with different attributes at different places. The species adapted differently with respect to the environmental conditions for survival.
Therefore, the correct order of the blanks is 4. offsprings, 5. artificial selection, 6. natural selection, 7. diversity and 8. adaptation.

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported
Answer:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.

The genome contains all of the DNA information needed to build and maintain an organism. In humans, the genome contains more than 3 billion DNA base pairs. Most of this genetic information is located in which of these structures within the cell?
Answer: A Genome is an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome, more than 3 billion DNA base pairs, is contained in all cells that have a nucleus.
In humans, a copy of the entire genome, more than 3 billion DNA base pairs, is contained in all cells that have a nucleus.
What do you mean by genome?The complete set of DNA (genetic material) in an organism. In people, almost every cell in the body contains a complete copy of the genome.
This set of instructions is known as our genome and is made up of DNA. Each cell in the body, for example, a skin cell or a liver cell, contains this same set of instructions. The instructions in our genome are made up of DNA.
The primary function of the genome is to store, propagate, and express the genetic information that gives rise to a cell's architectural and functional machinery.

Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants
Help me please
The primary mode of reproduction that separates flowering plants from non-flowering plants. While non-flowering plants need on dispersion to continue their life cycle, flowering plants depend on pollination for reproduction.
What is flowering plants and non-flowering plants?Seeds that are protected by a flower or fruit are used by flowering plants to reproduce.
Conifers, ferns, and mosses are examples of non-flowering plants. Conifers produce seeds in cones to reproduce. Spores are used in fern and moss reproduction.
The reproductive organs of plants, called flowers, transport both male and female gametes.
These flowers bear fruits once fertilised. Non-flowering plants are ones that reproduce by spores but don't produce flowers.
Plants differ in appearance, but they always share three characteristics: they are multicellular; they can produce their own food; and they are green.
Thus, these are some similarities between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.

What supports and protects animal bodies?
As fall arrived, Steven saw that many homes had chrysanthemums planted in their flowerbeds. Their golden colors always signal the oncoming fall season.
Many plants respond to seasonal changes.
Why might a plant such as a chrysanthemum bloom during the fall?
a. the plant may be conditioned to live in a particular climate
b. the plant may be better suited to survive in cooler weather
c. the plant may be unable to adapt to cold weather
d. the plant may not respond to seasonal changes
Answer:
A
Explanation:
Plants such as chrysanthemum bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.
What are the effects of seasonal changes on plants?The effects of seasonal changes on plants might be determined by the fact that plants also adapt to the seasons if they live in a place that has strong seasons. Plants will shed their leaves during the winter if there isn't enough light, or shed their leaves during the dry season if there isn't enough water.
This response of flowerbeds through chrysanthemums represents the significance of seasonal change through which plants increases their survival. This is due to the conditional behavior shown by plants in order to facilitate their survival in the natural ecosystem.
Therefore, plants such as chrysanthemums bloom during the fall because the plant might be conditioned to live in a particular climate. Thus, the correct option for this question is A.

How did the environment change? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. You cannot tell how the environment changed. With each generation, more guppies passed on the gene for small spots to their offspring.
2. The rocks became smaller. With each generation, more guppies with small spots survived long enough to pass on the gene for small spots to their offspring.
3. The rocks became smaller. Guppies with small spots are more likely to survive, so the guppies with large spots changed to have small spots.
4.The rocks became smaller. Guppies with small spots are more likely to survive, so both kinds of guppies passed on the gene for small spots to their offspring.
Answer:
1.you cannot tell how the environment changed. with each generation, more guppies passed on the gene for small spots to their offspring.
Explanation:
the diagram doesn't show/say anything about the environment changing. it just shows that at time 1 there were an equal amount of guppies with small and large spots and then the second one had more guppies with small spots, meaning that they must've reproduced more and began to outweigh the guppies with large spots.
