what are the advantages of classifying species according to their evolutionary relationships, instead of their physical similarities
Final answer:
Classifying species by evolutionary relationships provides a more accurate reflection of their shared ancestry and genetic heritage, which is essential for understanding the consequences of evolution and for updating classifications with new scientific data.
Explanation:
The advantages of classifying species according to their evolutionary relationships, rather than solely on physical similarities, are numerous. One key advantage is the ability to reflect the species' shared ancestry and evolutionary past. This phylogenetic classification offers a more accurate depiction of how species are related to one another and provides context for their physical and genetic traits. While physical traits can be misleading due to convergent evolution, where unrelated species independently evolve similar features, phylogenetic relationships are based on the genetic heritage that organisms share due to descent from a common ancestor.
What's evaluated at the G2 checkpoint in mitosis and meiosis?
A. That there are nutrients available for cell growth
B. That growth hormones are aligned and ready to be deployed to the new cells
C. That none of the DNA is damaged in the cell
D. That the cell is large enough to support division
Answer:
The correct answer is option C. That none of the DNA is damaged in the cells.
Explanation:
Control mechanisms in cells during cell division which ensure the proper division of the cells are called cell cycle checkpoints. There are three checkpoints in the cell cycle in meiosis or mitosis-
G1 checkpoint assesses the integrity of DNA. There is intermediate S checkpoint between G1 checkpoint and G2 checkpoint checks if DNA replication is completed or not.
G2 checkpoint checks or assesses the proper chromosome duplication and that none of the DNA is damaged in the cell.
M checkpoint assesses the attachment of every kinetochore to a spindle fiber.

the liver of dog has been found to have a higher than normal cell death because of dna is damaged. what part of the cell failed to do its job of protecting the dna of cell
Answer:
The Nucleus.
Explanation:
The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA.
Answer:
Nuclear envelop
Explanation:
Nuclear envelop is the double membrane structure that makes the boundary of the nucleus. It serves to protect the DNA from the toxins, wastes and other harmful substances produced during metabolic reactions of the cell occurring in cytoplasm.
If the nuclear envelope does not protect DNA, DNA could be damaged by free radicals or toxins. A cell with damaged DNA is subjected to death.

Julia demonstrated the formation of a type of rock. She mixed egg, salt, and herbs and cooked the mixture over a flame. The egg turned into an omelet. The formation of which type of rock did Julia demonstrate?
A.) Eroded rock
B.) Igneous rock
C.) Metamorphic rock
D.) Sedimentary rock
Answer: Option (C)
Explanation: Metamorphic rocks are those rocks that are formed when a pre-existing rock undergoes changes or metamorphism, due to the changing pressure and the temperature condition, and forms a new rock. For example, Quartzite, Marble, Schist and Gneiss. They are also known as the secondary rocks, as they are derived from the previous rock.
In the given condition, Julia mixes the egg with salt and herbs and cooked the mixture over a flame, this is compared to the changing pressure and temperature condition that rock undergoes, and that lead to the formation of her omelette, which is here compared to a metamorphic rock.

Explanation:
Heredity, or genetic inheritance, is a biological mechanism for transmitting characteristics from one individual to another (from parent to child specifically). The "bridge" that transmits such information is the gene, so everything happens in a genetic process.
Heredity is one of the foundations of genetics, a branch of biology that studies how biological inheritance occurs. This is how certain characteristics that differentiate a group are transmitted from one individual to another. A typical example of this phenomenon are the characteristics you have in common with your parents, such as eye color, hair texture, blood type and others.

How do human wingspans compare to albatross wingspans
Human wingspans are much smaller than those of albatross. That is, the ration of wingspan to height for humans is around 1.0, whereas for albatross it is closer to 3.0. ... Albatross fly thousands of miles each year. They use their long wings to soar on wind currents over the ocean.
An average human adult 'wingspan' measures around 2 meters, whereas the wingspan of the albatross, particularly the wandering albatross, can reach up to 3.7 meters - significantly larger. This reflects the different functions these 'wings' serve, with those of the albatross being specially adapted for long-distance flight.
Explanation:In comparing human wingspans to albatross wingspans, we find striking differences. The average human adult wingspan, that is, the distance from fingertip to fingertip with arms extended, usually measures around 2 meters (6 feet). In contrast, the wingspan of the albatross is considerably larger, with the wingspan of the wandering albatross - the record holder - reaching up to an impressive 3.7 meters (12.1 feet).
The differences in wingspan between humans and the albatross reflect the different roles and functions these 'wings' serve. For humans, our 'wings' or arms are used for manipulation and manual tasks, whereas the albatross uses its wings primarily for long-distance flight. The wings of the albatross are also intricately adapted for this function, with even the bird's flight muscles and skeletal structure playing major roles in facilitating efficient flight.

B. It made it possible to convert sunlight to glucose
C. It made it possible to move water within the plant structure
D. It allowed gametes to live longer without water supply
Answer:
It made it possible to move water within the plant structure
Explanation:
The development of vascular systems helped plants to move out because It made it possible to move water within the plant structure.
How vascular systems help plants to move out?
The plant vascular system is a complicated network of conducting tissues that interconnects all organs and transports water, minerals, nutrients, organic compounds, and various signaling molecules throughout the plant body. It is composed of two major tissues, xylem and phloem, that are differentiated from the procambium.
Vascular plants are successful due to better transportation for water, nutrients and reproduction. The xylem and phloem of the vascular bundles allow for distribution of water and food to all parts of the body. This structures allow vascular plants to colonize farther inland.
Vascular tissue allows a plant to exploit the moisture-holding capacity of soil to satisfy its water needs and also to grow stems to raise its leaves above the ground and its neighbors. Since access to light and moisture is critical for a plant to thrive and reproduce, vascularity has distinct competitive advantages.

I hope this helps you out a thank and a brainlist would be greatly appreciated.
Burning charcoal to cook a steak transforms electrical energy into thermal energy. Hence the correct option is C.
When charcoal burns, it undergoes a chemical reaction that releases heat, which in turn heats up the grill or cooking surface. This process transforms electrical energy (if the charcoal is ignited using an electric starter) or potential energy (if ignited manually) into thermal energy, which is used for cooking the steak.
Area measuring 5 m² contains 50 earthworms what is the population density of the earth worms
The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:
1,000 x 1,000 = 1,000,000 km²
Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:
1,000,000 x 10 = 10,000,000
So we have a density of 10 million earthworms per square km.
