Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.
Describe fertilisation in terms of cellular and intracellular changes. I will be very happy if someone answer this I will give them brainly and likes
Answer:
during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .
Cells responsible for fertilisation:
fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

A scientist observes a geyser erupting. Which two objects must be interacting beneath the surface?
O well and spring
O spring and magma
O magma and groundwater
O groundwater and unsaturated zone
Answer:
c
Explanation:
Magma and groundwater are responsible for the eruption of geyser.
GeyserGeyser eruptions are as a result of the conversion of thermal to kinetic energy during decompression.
When the groundwater deep in the ground is heated up by magma, pressure is released and the water will erupt out of the ground as a geyser. Eruptions occur about every 50-100 minutes.

A. as you move down the structure, the groups become more general
B. there are more organisms in each group as you move down the structure
C. as you move up the structure the group becomes more specific
D. as you move down the structure, there are fewer organisms in each group
Answer:
D. as you move down the structure, there are fewer organisms in each group.
Explanation:
When we move down from kingdom to species, the number of organisms decreases because more closely related organisms are placed down the group. There are fewer kingdoms that have a large number of organisms in it and has less similarities among them and when we move down, the number of organism decreases in number and at the end there are few organisms are present in it which is more closely related to each other.
are all cells going through the cell cycle at the same speed? why or why not?
Answer: Not all cells move through the cell cycle at the same rate. Proteins that regulate the timing of the cell cycle. Most of the differences in cell cycle duration between species and cells are found in the duration of specific cell cycle phases. DNA replication, for example, generally proceeds faster the simpler the organisms.

Which student’s answer describes and explains an internal adaptation that allows for a specific function?
Explanation:
As internal adaptation refers to anatomical adaptation so correct option is B - Student 2: Birds have hollow bones, enabling them to fly.
The bones of birds have hole openings inside. Therefore, chicken bones are much less dense than human bones. These hole areas purpose the chicken to have lighter mass, permitting a less difficult raise for flight. Birds additionally have air sacs which can be extensions of their lungs. Hollow bones also are referred to as pneumatized bones, which means they may be full of areas for air. It is the notion that this shape allows for oxygen consumption throughout the flight. Air sacs are connected to the hole regions in a chicken's bones.What is the use of feathers?Birds have feathers that assist them to fly. The lengthy flight feathers at the wings and tail assist birds' stability and steering. In addition, birds have a device of air sacs of their frame that hook up with the lungs. The air sacs permit birds to extract plenty greater oxygen from every breath of air than different animals can.
Thu it is clear that birds have hollow bones, enabling them to fly is an internal adaptation.
