Answer:
The answer is: After step 3, layers of sediment cover the dead organism.
Explanation:
Fossilization is the process by which living things are preserved as impressions on sedimentary rock (fossils). This is a rare process that occurs under the most appropriate conditions.
Process of Fossilization:
Permineralization is one of the most common types of fossilization. It involves the absorption of minerals into the remains, giving a detailed impression of the dead organism.
- The dead organism sink to the bottom of the ocean.
- The soft parts i.e. the tissue is decomposed whereas the hard parts of the body: the nails, bones and hair remain.
- The bones are gradually covered by sediments. The quality of the fossils often depends upon the type and quantity of sediment. River deltas have a large amount of sediment. This speeds up the process. Clay and mud sediments provide more detail to the fossil whereas sandy sediments render the details vague.
- Sedimentation is followed by permineralization. As layers of sediment accumulate over each other, the layers underneath turn to rock. This occurs due to the movement of minerals down to the seabed that harden the sediments. Minerals such as calcite may even replace the bones and other hard parts of the fossil, allowing it to remain preserved for long.
- The fossils discovered by archaeologists are present relatively closer to the surface of the Earth. This occurs due to the uplifting of rock layers due to the movement of the continental plates.
Answer: Calcium: not enough calcium can lead to rickets, osteopenia and osteoporosis. Iodine: not enough iodine can cause goitre and other conditions like intellectual disability. Iron: children are at higher risk of iron deficiency than adults, mainly because children need more iron when they go through growth spurts
Explanation:
<span>The third option:</span><span>This statement is true because every step in protein synthesis requires enzymes, which are nothing but proteins.</span><span>
</span>I mean if you look at rRNA which is needed to make polypeptide chains, it is 2/3 protein, and then the helices, ss binding proteins, DNA polymerase and everything in transcription is protein.
So that last option/ third option is the best
The answer is <span>A) stimuli receiver, sensory neuron, central nervous system, motor neuron, muscle or gland.
Stimuli receiver receives an information. </span><span>The information is sent through a sensory neuron to the spinal cord, as a part of the central nervous system. </span><span>The spinal cord receives information from the body and relays it to the brain. It, then, receives information from the brain and relays it out through a motor neuron to the effectors (muscles or glands).</span>
Answer: Genetic engineering is manipulating or modication an organisms' dna or cells.
Cloning is a great example of genetic engineering.
Explanation: it is important because it is use to produce medicine such as Insulin and other vaccines for dfferent diseases.
Hope this helped :)
