List the four stages of coal formation.
Answer:
eat, lignite, bituminous, and anthracite.
Explanation:
The stage depends upon the conditions to which the plant remains are subjected after they were buried: the greater the pressure and heat, the higher the rank of coal.
Answer:
There are four stages in coal formation: peat, lignite, bituminous, and anthracite.
Explanation:
Stage one: Peat is the first stage in the formation of coal. Normally, vegetable matter is oxidized to water and carbon dioxide. However, if plant material accumulates underwater, oxygen is not present and so only partial decomposition occurs. This incomplete destruction leads to the accumulation of an organic substance called peat. Peat is a fibrous, soft, spongy substance in which plant remains are easily recognizable. It contains a large amount of water and must be dried before use. Therefore, it is seldom used as a source of heat. Peat burns with a long flame and considerable smoke.
Stage two: Lignite, the second stage, is formed when peat is subjected to increased vertical pressure from accumulating sediments. Lignite is dark brown in colour and, like peat, contains traces of plants. It is found in many places but is used only when more efficient fuel is not available. It crumbles easily and should not be shipped or handled before use.
Stage three: Bituminous Coal is the third stage. Added pressure has made it compact and virtually all traces of plant life have disappeared. Also known as “soft coal”, bituminous coal is the type found in Cape Breton and is our most abundant fuel. It is greatly used in industry as a source of heat energy.
Stage four: Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre. It appears to have been formed as a result of combined pressure and high temperature. Anthracite burns with a short flame and little smoke.
Which of the following is NOT a structural adaptation?
camouflage
mimicry
spikes on a hedgehog
a squirrel climbing up a tree
Answer:
Camoflauge.
Explaination:
Camouflage is when a species changes to resemble its surroundings to protect itself.
Structural adaptations are physical features of an organism such as spikes on a hedgehog.
Since camoflauge is not a physical feature, it is therefore not a structural adaptation.

what would happen if sister chromatids were not pulled apart at anaphase 2
Answer and Explanation: Nondisjunction occurs when sister chromatids are not pulled apart at anaphase II. This will cause both sister chromatids/ homologous chromosomes to be pulled to just one pole of the cell.
Since the anaphase I stage in Meiosis I occurred without errors, this would result in four haploid gametes being produced.
However, two of these gametes will be normal, will have the normal number of chromosomes. The other two gametes would have an abnormal number of chromosomes and be aneuploid. One would have n+1 number of chromosomes, and the other would be n-1.

Which of the following conditions must be met for evolution by natural selection to occur within the rabbit
population?
Some individuals in the rabbit population must evolve traits that improve their survival chances.
Some rabbits must acquire mutations that create genetic variation within the population.
Rabbits must be capable of producing more offspring than are able to survive.
Rabbits must decrease their rate of reproduction to decrease competition for resources.
In the grassland ecosystem, rabbits must be capable of producing more offspring than are able to survive, this condition must be met the evolution by natural selection to occur within the rabbit population. Thus, the correct option is C.
What is Natural selection?Natural selection is the process through which different populations of living organisms adapt and change according to the surrounding environment. Individuals in a population are naturally variable with respect to environmental conditions, meaning that they are all different in some ways or the other. This variation in population means that some of the individuals have traits which are better suited to the environmental conditions than that of others.
Rabbits must be capable of producing more offspring than they are able to survive. This conditions must be met for the evolution by natural selection to occur within the rabbit population.

Which of the following best describes invertebrates and vertebrates? Invertebrates have a backbone and vertebrates do not. Invertebrates do not have a backbone and vertebrates do. Invertebrates and vertebrates both have a backbone. Invertebrates have a backbone in the front and vertebrates have one in the back.
Answer:
Explanation:Invertebrates are animals without spines, while vertebrates have a spine. Invertebrates are sometimes (mistakenly) thought of as primitive because of their lack of developed organs. Their simple internal systems include respiratory systems such as gills or trachea and they often use an open circulatory system to pump their blood. As invertebrates lack an internal skeletal
structure, they sometimes have an external skeleton that protects their soft bodies called an “exoskeleton.” In general, invertebrate success often comes from their ability to reproduce extremely quickly, unlike many vertebrates who take years to become fully grown.
Vertebrate animals, on the other hand, have a spine that develops from a notochord they possess as an embryo. They also have defined internal systems like complex respiratory structures, a closed circulatory system and sensory organs that build the nervous system. Vertebrates tend to be larger than invertebrates, thanks to their backbone, which allows their bodies to grow larger and move faster than many invertebrates.
The statement that best describes invertebrates and vertebrates is invertebrates do not have a backbone and vertebrates have a backbone.
What do you mean by invertebrates?Invertebrates may be defined as any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates.
Invertebrates do not possess a backbone and an internal skeleton, but they have an exoskeleton. They possess an open circulatory system. While on the other hand, vertebrates possess a backbone and an internal skeleton, but they do not possess an exoskeleton. They possess a closed circulatory system.
Therefore, the statement that best describes invertebrates and vertebrates is invertebrates do not have a backbone, and vertebrates have a backbone.

Although the cause of Parkinson's disease is unknown,research indicates that it may be due to defective nuclei in the cells of those affected.Which of these could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson
Answer:
Nervous System could be studied as a direct result of having defective nuclei and may shed light on the cause of Parkinson .
Explanation:
PASRKINSON DISEASE -: Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.
A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).
Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.
Hence , the answer is the nervous system and other regions of brain where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .

What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?
RESPOND ASAP
Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods into the blood. These cells have external growth that facilitates the reabsorption by increasing the surface area.
What is the intestine?The intestine is divided into two parts, such as the small intestine and the large intestine, The small intestine is responsible for digestion, while the large intestine is responsible for fecal excretion. The enzymes are secreted, complete digestion happens in the small intestine, the digested food is reabsorbed into the blood, and the cells that carry out the reabsorption have external grooves called villi. These villi increase the surface area of the small intestine so that more absorption can occur and cells get enough nutrition for cellular metabolism.
Hence, Certain cells need to absorb a lot of materials, such as the cell of the small intestine that reabsorbs the digested foods, which has villi as a special feature of the cell.

Why are there so few third-level consumers and how does this fit with the energy pyramid? Group of answer choices because there is less energy available at the bottom of the pyramid because of the energy and heat loss at each level of the pyramid because they use the most energy competing for food in the pyramid because they have the fewest sources of food for energy in the pyramid
Answer:
because of the energy and heat loss at each level of the pyramid
Explanation:
Producers (photosynthetic beings) are the ones who are at the base of the food pyramid, and for this reason, they are the ones with the most energy availability. ,
When a primary consumer feeds on producers, the energy stored in organic compounds is transferred to him. Consumers then use ingested organic matter to produce energy, which, in turn, is used to carry out some processes for their survival. Another part of the substances ingested is lost in feces and urine.
When serving as food for another organism, primary consumers transfer their energy to that secondary consumer, and so on. Therefore, at each level of the pyramid, less energy is passed, and then less energy is available, the more difficult and competitive it becomes for subsequent consumers.
