Answer:
a. aquatic insects
Explanation:
Aquatic insects constitute an important component of freshwater aquatic biodiversity. In addition to being very abundant in rivers and streams, they are also present in lakes and temporary water stagnations (wetlands). In water sources, these insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. Aquatic insects have different eating habits and therefore have multiple behavioral and morphological modifications.
Aquatic insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. According to the place where they live and the availability of resources, these insects have different eating habits. In this line, we have predatory aquatic insects of other insects or vertebrates such as turtles (access contents about turtles) and fish, feeding on living tissue of vascular plants and detritivorous habits that means that they feed on organic matter in suspension in the water column.
In the evolutionary history of aquatic insects, due to diversification in eating habits, they have modifications in their body appendages. In this context, we have predatory aquatic insects with raptorial legs to hold the prey, with a raptorial lip like dragonflies for the same purposes, and other detritus filters have multiple mushrooms on the anterior legs and mouth structures to retain organic matter.
According to the mode of acquisition of food, we have predators that actively forage in search of prey such as dragonflies, also passive predators such as hemiptera of the Belostomatidae family. Detritivorous aquatic insects, meanwhile, can be filters, crushers, collectors or scrapers of organic matter.
Meiosis is the reductional division which takes place in organisms which reproduce by the process of sexual reproduction. It produces haploid cells to maintain the chromosome number constant in the offpsring.
Meiosis is a type of cell division which results in the reduction of chromosome number in the cell by half of its original number. Meiosis is also known as reductional division.
Meiosis takes place in the process of formation of gametes in the organisms which reproduce by sexual mode of reproduction. In meiosis, four daughter cells are produced, which are haploid. The male and female gametes produced by meiosis under fertilization to form zygote which is diploid. If the gametes were not haploid then the offspring will show presence of extra set of chromosome which can lead to chromosomal disorders.

Answer:
The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell. "Meiosis is reductional," said M.
What is the purpose of cell division?
A Growth of new cells
B Replacement of older, worn out cells
Used for reproduction
D
All of the above
Answer: All of the above.
b. carbon
c. oxygen
d. nitrogen
Answer:
The answer is B. carbon Earth's greenhouse effect directly related to the carbon cycle hopefully this helps!
Sandstone, shale, conglomerate, and breccia are examples of clastic sedimentary rocks. They form when rock fragments, or clasts, are eroded, transported, and deposited in layers. Over time, they become compacted and cemented together to form sedimentary rocks.
Four examples of clastic sedimentary rocks include sandstone, shale, conglomerate, and breccia. These rocks form through a process called lithification. Initially, weathering breaks down pre-existing rocks into small fragments or particles. These particles, known as clasts, are then transported by natural forces like wind, water, or ice in a process known as erosion. Over time, these clasts build up in layers and eventually get compacted and cemented together to form sedimentary rocks.
Sandstone, for example, forms from sand-sized clasts, often in desert dunes or riverbeds. Shale is made of clay or mud-sized particles and often forms in calm water environments like lakes or deep sea beds. Conglomerates consist of large, rounded clasts and often form in fast-moving rivers. Breccia, on the other hand, is formed from large, angular clasts and usually forms near mountainous regions where there is a high rate of mechanical weathering.
