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).

"When the temperature increases, the rate of a catalase activity increases. When the temperature decreases, the rate of a catalase activity decreases."
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.
Why is it important for gametes to be haploid cells?
The reason why it is important for gametes to be haploid cells is because: when the sperm and the egg fuse together the living sex cells will have 46 chromosomes.
Gametes are also referred to as sex cells and they can be defined as the reproductive cells in a living organism.
Generally, the male reproductive cell is known as a sperm while the female reproductive cell is known as an egg.
Since gametes are reproductive cells or sex cells, they are typically made up of haploid set of chromosomes.
Basically, it is very important for gametes to be haploid cells so that when the sperm and the egg fuse together, the living sex cells will have a total of 46 chromosomes.

Why is oceanic crust younger than continental crust?
Oceanic crust is younger than continental crust because it undergoes continuous formation and destruction through seafloor spreading and subduction.
The age difference between oceanic crust and continental crust is primarily due to the process of plate tectonics. Oceanic crust is constantly forming at mid-oceanic ridges through a process called seafloor spreading. This occurs when molten material from the mantle rises to the surface and creates new crust. As new crust forms, older crust is pushed away from the ridges, gradually moving away from the spreading center.
In contrast, continental crust is older because it is not continuously formed or destroyed like oceanic crust. Continental crust is composed of various rocks, including granite, and is typically thicker and less dense than oceanic crust. It is primarily formed through the collision and accretion of tectonic plates over long periods of time.
Additionally, oceanic crust is also subject to subduction, where denser oceanic plates are forced beneath less dense continental plates. This process occurs at convergent plate boundaries. When oceanic crust subducts, it is eventually recycled back into the mantle, which contributes to the overall young age of the oceanic crust.
In summary, the continuous formation of new oceanic crust at mid-oceanic ridges, along with the subduction of older oceanic crust, results in the relatively young age of oceanic crust compared to the older continental crust.

mitosis is a process of body cell formation, while meiosis is a process of reproductive cell formation. i hope i helped (instagram itzactuallytif)
Answer:
: Mitosis and meiosis both are the types of cell division which occurs in the body of living organisms. Mitosis is responsible for growth and development in the body of cat because in mitosis, one cell is divided into two daughter cells and again these two cells divided into four and so on which increases size of organisms, while meiosis is responsible for the production of sex cells in cat which enables them to continue its breeding and produce fertile offspring.

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.

Which of the following statements is true about sensory cells in the gustatory system? Sensory cells migrate to the edge of taste buds to die after a month. Sensory cells last a very long time and are renewed about once a year. Sensory cells are located near the center of the taste bud when renewed. Sensory cells last approximately two weeks and are renewed frequently.
Answer:
Sensory cells last approximately two weeks and are renewed frequently.
Explanation:
Sensory cells last approximately two weeks and are renewed frequently. The correct option is D.
What is gustatory system?The gustatory system is the sensory system in charge of taste and flavor perception.
The gustatory system in humans is made up of taste cells in the mouth (that also detect the five texture and flavor methodologies: salty, sweet, bitter, sour, and umami), several cranial nerves, and the gustatory cortex.
Sensory cells are cells with receptors on their surface that detect information (such as sounds, light, touch, smell, taste, and temperature). This information is transmitted from sensory cells to the brain via nerves.
Taste receptor cells function similarly to neurons, but, like epithelial cells, they are rapidly and continuously renewed throughout adulthood.
Sensory cells have a lifespan of about two weeks and are constantly renewed.
Thus, the correct option is D.

What allows the three atoms in a water molecule to stay together
Answer:
Three types of bonds hold atoms together within molecules: ionic, covalent, and polar covalent. ... Hydrogen bonds allow two molecules to link together temporarily. • Water molecules are made up of two hydrogen atoms and one oxygen atom, held together by polar covalent bonds.
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Thus, option A is correct.
What are covalent bonds?A covalent bond is the exchange of electrons between atoms. This type of bond occurs between two atoms of the same element or elements that are close to each other in the periodic table.
Strong linkages—called covalent bonds—hold together the hydrogen and oxygen atoms of individual H₂O molecules.
Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge.
Therefore, covalent bonds formed by shared electrons of hydrogen and oxygen atoms of individual H₂O molecules. Thus, covalent bond allows the three atoms in a water molecule to stay together. Thus, option A is correct.

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

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
