Answer:

The correct option is ( have a respiratory system with spiracles connecting to tracheae).

Explanation:

The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.

An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.

An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.

Answer:

Methods of waste disposal are :-

Biogas plant: - Biodegradable material is used to produce biogas and manure.

Sewage treatment plant: The drain water is treated at plants before adding it to river.

Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.

Composting: - Organic waste are filled in compost pit to make compost for plants.

Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.

Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.

Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.

Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Answer:

Glycolysis and Krebs cycle.

Explanation:

During cellular respiration, the first carbondioxide gas is generated during glycolysis while the remaining carbons are given off as carbondioxide during Krebs cycle. During the process of glycolysis in cellular respiration, glucose is oxidized forming carbondioxide and water whereas during the Krebs cycle, the two carbon atoms of acetyl-CoA are released and each turns into a carbondioxide molecule.

Answer:

there are no possible changes adaptations

Explanation:

what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out

If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.

The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.

Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

Cerebral cortex.

Explanation:

The masses of gray matter that lie deep within the cerebral hemispheres is called cerebral cortex. The cerebral cortex is responsible for many brain functions such as sensation, perception, memory, association, thought, and voluntary physical action. Damage occur to cerebral cortex can leads to many cognitive, sensory, and emotional difficulties in the body. It is also responsible for regulating intensity and precision of voluntary movement.

About 20,000–25,000 genes make up the human genome.

Genome of an organism refers to the total genetic makeup of that organism. It includes all the genes present in the organism.

Genes are the basic unit of inheritance found on (deoxyribonucleic acid DNA).

A project called Human Genome Project worked to determine the sequence of the human genome and its constituent genes and it was estimated that humans have between 20,000 and 25,000 genes.

Answer:

C

Explanation:

The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.

Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.

Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.

The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.

The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.

Therefore, option C. the less permeable roads cause rainwater to become runoff.

Answer:

Conservation biology as a discipline aims to provide answers to specific questions that can be applied to management decisions. The main goal is to establish workable methods for preserving species and their biological communities.

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.
