Answer:
In relative dating, fossils are dated according to the depth at which they were buried. ... While in the absolute dating, isotopes of carbon are used for dating fossils. The absolute dating is more precise than relative dating because it tells the exact age of the fossils.

The ocean sunfish (Mola mola) is a large, flat fish that spends most of its time in deep water
feeding mainly on jellyfish, Sunfish often have many species of copepods, small crustaceans,
that bury their heads into the soft tissue of the sunfish, Sunfish will swim to the surface of the
water and lie sideways, allowing seabirds to eat the copepods from their skin,
Which list describes the types of relationships the sunfish has with other marine organisms?
The group of choices is given below :
a. Seabirds: mutualism
Jellyfish: predation
Copepods: parasitism
b. Seabirds: parasitism
Jellyfish: commensalism
Copepods: predation
c. Seabirds: predation
Jellyfish: mutualism
Copepods: commensalism
d. Seabirds: commensalism
Jellyfish: parasitism
Copepods: mutualism
Answer:
The correct answer is option A. Seabirds: mutualism
Jellyfish: predation
Copepods: parasitism
Explanation:
In this given example sunfish have three different relationships with all three organisms that are related to it tat are seabird, jellyfish, and copepods.
With seabirds, sunfish shows mutualism as they both get benefitted from their relationship in which seabirds feed on copepods and sunfish get rid of their parasite.
With jellyfish, sunfish feed on the jellyfish mainly which suggests that they are predator and jellyfish are prey and their relationship is of predation.
With copepods, copepods bury their heads on the soft tissue of the sunfish so they are parasite on the sunfish that is example of the parasitism
Answer:
A. Seabirds: mutualism
Explanation:
A. Seabirds: mutualism
Jellyfish: predation
Copepods: parasitism

Explanation:
A biologist collects DNA samples from two sisters. The younger sister has blond hair. The older sister has red hair. The sisters have different traits because their DNA contains different —
A---order of nucleotides
B---types of sugar molecules
C---sized phosphate groups
D---types of nitrogenous bases
PLZ ANSWER IF U ARE ONLY SMART AT THIS STUFF
The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).
DNA is a double helix composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.
During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.
The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.
In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

How are the agents of weathering similar and different.
Answer:
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. ... Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
Physical weathering breaks down rocks without changing their proportion, whereas chemical weathering changes the ingredients that cause up the rocks. Depending on the chemicals used, the rock may completely disintegrate or simply become softer and more susceptible to other forms of weathering.
What is weathering?Weathering occurs when rocks, land formations, and minerals begin to break down and dissolve.
The process of erosion transports these broken bits away by wind or rain after they crumble.
Weathering agents include ice, salts, water, wind, and plants and animals. Road salt and acids are examples of chemical weathering because they contribute to the erosion of rocks and minerals.
Thus, these are some of the similarity and differences of weathering.

What is the importance of water in human activities?Water is essential for healthy ecosystems, socioeconomic development, food and energy production, and human existence, which is at the heart of sustainable development.
As the vital link between society and the environment, water is also at the core of adaptation to climate change.
By serving as a solvent, water is an essential component of the majority of biological activities. Food is absorbed into our bodies as solutions using water as the solvent. Additionally, a lot of waste materials are eliminated as solutions through sweat and urine. Our body temperature is regulated by water. Therefore, option D is correct.

Which of the following would not be considered an observation in terms of the scientific method? A. tasting a pasta sauce after adding a new ingredient B. looking at a blood sample through a microscope C. a dog buries a bone in the backyard D.listening to bats of different materials hitting a baseball
Answer:
C. a dog buries a bone in the backyard
Explanation:
A dog burying a bone in the backyard is not an observation in terms of scientific methods.
Observation is the process of acquiring data about a phenomenon under study.
Most times, senses are used in making observations. Our sense of taste, hearing, sight etc. comes handy when making observation.
Also, we can use some specialized equipment to make observations.
A dog burying a bone in the backyard is not an observation. None of the senses nor instruments are used to gather any relevant information.DNA molecules separate into single strands, which are then used to construct two identical strands of DNA. This process ensures that the-
Answer:
DNA replication will occur properly...!
Explanation:
The process ensures that the daughter cells are genetically identical to the cells of the parent.
DNA molecules separate into single strands, which are then used to construct two identical strands of DNA. The two strands wind around each other.
The strand of DNA has a backbone that's made of alternating sugar and phosphate groups. The daughter cells formed are genetically identical to the cells of the parent. They contain identical chromosomes just like their parent cells.

Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data
Answer:
simple:
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

Hope I helped
Explanation: i watched like 20 times
Answer:
Consume already dead meat - when Scar brings the Hyena food because that food is already dead.
Kill and Consume young, sick, or small animals - When one of the Hyenas wants to eat one of the smaller or sick animals at the Stampede scene.
A pack kills larger weakened animals - I guess that could be when Scar kills Mufasa because he is already weakened or when the Vultures are trying to eat Simba because he is tired and weak from walking.
