Fossils-preserved remains or traces of what
Answer:
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils range in age from 10,000 to 3.48 billion years old. The observation that certain fossils were associated with certain rock strata led 19th century geologists to recognize a geological timescale.

What conclusion about the bacteria domain could be made from the phylogenetic tree below?
Plants and animals evolved from the Bacteria domain.
Bacteria and Eukarya are more similar than Archaea and Eukarya.
Eukarya has similar evolutionary traits to Archaea.
Eukarya and Bacteria developed on the same evolutionary line.
Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.

n
= one half of the total genetic material of a human cell
Answer:c
Explanation:
The diagram that correctly represents a step in the normal process of human reproduction is n + n = 2n (Option C).
Meiosis is a reductional type of cell division that produces four daughter haploid cells.These meiotic haploid (n) cells are known as gametes or germinal cells.During fecundation, two different germinal cells fuse to produce a diploid zygote.In conclusion, the diagram that correctly represents a step in the normal process of human reproduction is n + n = 2n (Option C).

Why do scientists often use bacteria to produce medicines?
Scientists often use bacteria to produce medicines because of their easy use, genetic manipulability, and genetic ability to produce medicine.
What are the characteristics of bacteria?Scientists often use bacteria to produce medicines because bacteria grow quickly and can be cultured in large quantities. This makes them a cost-effective option for production of large amounts of medicine.
Bacteria also have a simple genetic makeup that is easy to understand that allow scientists to easily produce proteins. Some bacteria have the ability to produce natural compounds containing medicinal properties, such as Streptomyces produces several antibiotics that are used in medicines.
Bacteria can also be genetically engineered to produce new compounds that can be used as new medicines. Bacteria are highly versatile for production of wide range of medicines.
Therefore, bacteria are used for producing medicines because of easy use, genetic manipulability, and genetic ability to produce medicine.

Which organisms are more closely related, [bears and lizards] or [bears and newts]? How do you know?
Answer:
Bears and lizards are more closely related.
Explanation:
The chart shows the branches of the species. The relativity of each species to each other shows how closely related they are.
organisms that are placed close to each other and have a nearly common ancestor have some similarities, so the bear and the lizard are closer to each other than the newt because they are closely present in the cladogram.
What is the cladogram?The cladogram is the diagrammatic representation of the animals and shows how the organisms have evolved and their special traits. This cladogram explains how the species show commonness and difference, such as the bear and the chimpanzee, which are both derived from the common mammal ancestor.
From the common amneote ancestor, the lizard, bear, and chimpanzee are descended, so they all have the traits of the amneote. From a common tetrapod ancestor, the newt, the lizard, the bear, and the chimpanzee are derived, and all have some characteristic of the tetrapoda.
Hence, the bear and the lizard are closer to each other than the newt because they are both present closely in the cladogram.

The correct options for the given question about Sternum are "All the Options"
What are the functions performed by Sternum ?The bone known as the sternum is situated in the centre of our chest. It's also known as the breast bone.Our sternum performs two crucial tasks, one is Protection and other one is Support.The sternum and ribs serve to shield the torso's internal organs, including the heart, lungs, and blood arteries in the chest.Our collarbone and the majority of our ribs link to the sternum, as well as other skeletal components. A few of the muscles in our upper abdomen and chest are also connected to the sternum.Thus we conclude that our sternum performs all the functions listed in the question which include protection of kidneys, protection of heart, connection with the ribs, connection with the pectoral girdle, connection with the vertebrae, protection of the brain and many more.

Adult axolotls are typically aquatic, with gills and underdeveloped limbs, as shown in the image. Under certain conditions, an axolotl can undergo metamorphosis to its terrestrial form, which has completely developed limbs and lungs instead of gills.

Based on this information, what is most likely true about the effect of iodine on axolotls?
A. Iodine is toxic to the aquatic form of the axolotl.
B. Iodine influences the expression of the genes that control metamorphosis.
C. Iodine causes mutations in the genes that regulate metamorphosis.

According to the law of conservation, both energy and matter are conserved in the natural system. Earth as a whole is a closed system, in which energy and matter can move from one sub-system to another.
As energy and matter are transferred between subsystems, different forms of matter and energy interact. For example, during photosynthesis, carbon is transferred from the atmosphere into the biosphere, while radiant energy from the sun is converted into chemical energy.
During this process, the amount of carbon remains constant, but some of the radiant energy is transformed into electrical energy.
What is the Law of conservation?The law of conservation may be defined as a physical property that can not change in the course of time within an isolated physical system.
