Answer:
C. is the correct answer. Sea level, Pacific Ocean, 1955 to 1975.
Explanation:
Letter C is the correct link because you are looking for the change in the height of an ocean over a 20 year period of time.
The reason for this is because A only has names of oceans, therefore wouldn't help you find the changes in height or the number of years. B has volume, density, and temperature, but you are not trying to find the mass of the ocean. Finally, D has the wind speed, pH, and salinity, and you are not looking for any of those.

Answer: c. Sea levels, Pacific Oceans, 1955 to 1975
Explanation:
Why do individual water masses within the oceans retain distinctive physical properties for long periods?
Water's polarity and unique properties, such as high heat capacity and heat of vaporization, enable individual water masses within the oceans to retain distinctive physical properties for long periods.
Explanation:Water's polarity allows for the formation of hydrogen bonds between adjacent water molecules, resulting in many unique properties that are critical to maintaining life. For example, water is an excellent solvent because hydrogen bonds allow ions and other polar molecules to dissolve in water. Water's hydrogen bonds also contribute to its high heat capacity and high heat of vaporization, resulting in greater temperature stability. Hydrogen bond formation makes ice less dense as a solid than as a liquid, insulating aquatic environments. Water's cohesive and adhesive properties are seen as it rises inside capillary tubes or travels up a large tree from roots to leaves. The pH or hydrogen ion concentration of a solution is highly regulated to help organisms maintain homeostasis; for example, as will be explored in later chapters, the enzymes that catalyze most chemical reactions in cells are pH specific. Thus, the properties of water are connected to the biochemical and physical processes performed by living organisms. Life on Earth would be very different if these properties were altered—if life could exist at all.

explain how enzymes activity is affected by the PH and concentration of the substrate?
Answer AND Explanation:
pH refers to the acidity or alkalinity of a substance. Most enzymes have an optimum pH close to 7 which is the intracellular pH. If the pH changes from the optimum for an enzyme, the rate of enzyme activity decreases. Extreme changes of pH denatures the enzyme.
When the substrate concentration is increased, the rate of an enzymatic reaction also increases up to a maximum level. Further increase in substrate concentration does not result in an increase in the rate of reaction because all the active sites of an enzyme are occupied.

They are helpful in fighting with the germs but at times it starts acting against the bodies healthy cell these also reduces the person’s immune system. There is a test that checks how the antibody is working against the red blood cells i.e. Coombs test. Antibodies can be found in the body fluid as it moves through the bloodstream.
How does reproductive isolation cause speciation ? Apex
Reproductive isolation leads to speciation because it prevents the exchange of genes between two distinct populations of organisms.
This implies that mutations can happen independently in the two populations, resulting in differences in each group that do not exist in the other.
When a species of bird experience reproductive isolation, for instance, if one bird began hunting at night rather than during the day and eventually began to live at night.
According to the biological species idea, this causes distinct features to be selected for in the night bird population compared to the day bird population.

Other than passing genes from parents to offspring, bacteria are also capable of injecting their genes directly into other bacteria. Using complete sentences, explain how this speeds up the process of evolution in bacteria using either inherited variation, competition, or differential reproductive success.
Explanation:
Bacteria usually divides by fission. This produces offspring that are the exact copies of the parent unless a mutation occurs in the offspring.
Occasionally, however, bacteria cells exchange genetic material through conjugation. This exchange is akin to crossing over in higher organisms, result in genetic recombination of the bacterial DNA. This increases genetic diversity of the bacteria cells in the population. This genetic diversity improves the population's success in adapting to changes in the environment.

PLEASE HURRY!!!!!!!!!!!
Answer:
The answer is c, becuase the seeds will get caught in the birds feathers, the bird will carry the seeds and the seeds will pollinate everywhere
Explanation:
Final answer:
A bird getting seeds stuck in its feathers as it moves around the woods (Option C) is the correct answer, as this represents a form of external seed transportation and dispersal.
Explanation:
The correct answer that represents an animal actively involved in seed dispersal is: C. a bird getting seeds stuck in its feathers as it moves around the woods
This is because animals and birds can spread seeds in various ways. One such way is through external transportation, where seeds stick to the animal's fur or feathers. The seeds can then be transported to different locations, increasing the geographic range of the plant species. For example, some fruits, like the cocklebur, have hooks or sticky structures designed to adhere to an animal's coat.
Other methods of seed spreading include animals burying seeds like squirrels stashing away acorns, which may later germinate if the animal forgets its cache. Moreover, when animals and birds consume fruits and the seeds pass through their digestive system undigested, they can be excreted in their droppings, sometimes far from the original source, leading to the spread of seeds.
Why is it important that the
substance DNA is placed in for
electrophoresis be porous?
It important that the substance DNA is placed in for electrophoresis be porous because,
DNA are placed in the electrophoresis gel, so that the pores present can limit or check the movement of the DNA by creating a surrounding in which individually DNA fragment rate of motion can vary based upon their length. The gel is nothing but a permeable matrix. The motion of charged molecule defined as the migration. The molecules migrate towards the opposite charge. The molecule having negative charge will be attracted towards the positive charge.
The porous substance in electrophoresis facilitates movement of charged particles, ensuring accurate separation based on size or charge differences.
It's important for the substance used for electrophoresis to be porous because electrophoresis relies on the movement of charged particles through a medium under the influence of an electric field. Porous substances allow the charged particles, such as DNA fragments, to move through the medium more easily, facilitating separation based on size or charge. If the substance were not porous, the movement of charged particles would be hindered or even prevented, resulting in inaccurate or incomplete separation during electrophoresis. Thus, the porosity of the substance ensures efficient and effective separation of DNA fragments based on their size or charge differences.

Both mitosis and meiosis begin with a parent cell that is diploid. Which of the following best describes how mitosis and meiosis result in daughter cells with different numbers of chromosomes
Answer:
meiosis you will have four haploid cells (half the number of chromosomes is a diploid cell) and after mitosis you will have two diploid cells
Explanation:
Mitosis you begin with a parent cell that is haploid, it copies all it's chromosomes and splits so each daughter cell have the same number of chromosomes as the parent cell so both being diploid
In meiosis the chromosomes fold over DNA and are put in pairs, in the first division the pairs are split up evenly into two cells randomly (diploid still) but the the cells split the chromosomes in half in them creating four grneticly different haploid cells
Mitosis and meiosis are the two types of cell division. In mitosis, the parent cell forms two daughter cells that are genetically alike and have the same number of chromosomes.
In meiosis germ cell divides into four gametes with half the number of chromosomes, they take place in reproductive cells.Both mitosis and meiosis begin with a diploid parent cell. In mitosis, the parent cell is a haploid that divides and forms two equal daughter cells that have the same number of chromosomes. So both the parent and daughter cells are diploid.In meiosis, the chromosomes get divided into two equal daughter cells but again a division occurs and the chromosomes get divided into half. This results in the formation of four daughter cells which are haploid in nature.Therefore, in mitosis, you will get two diploid daughters and in meiosis, you will get four haploid daughter cells.

Which type of gene is most likely to be widely expressed in the body of someone who has superficial scrape?
Missing options in the question:
the gene that controls the production of stem cells
the gene that controls the production of skin cells
the gene that controls the production of red blood cells
the gene that controls the production of cardiac cells
Answer:
B. the gene that controls the production of skin cells
Explanation:
Superficial scrapes are the damages of upper skin layers which could occur due to accidents or sunburning. Upon damaging, body sheds the skin cells and then replaces with new cells. This process thus is governed by the expression of skin related genes.
Answer:
A gene that stimulates and controls the production of white blood cells.
Explanation:
First, it is necessary to know that a gene is a sequence of DNA that has information for the formation of molecules necessary for the body. These molecules can be proteins, cells, enzymes, among other things that are needed at that very moment.
When a person on superficial scratches, the skin cells send a signal that it is necessary to defend the injured part from possible invaders that could harm the organism. At that moment, the genes come into action and are quickly expressed, not all of the organism's genes, but only those that contain information for the production and control of defense cells, the white blood cells, which will prevent invaders from using the scratches as entry into the body and cause damage.

how did the industrial revolution relate to the genetic changes, occurring in the peppered moth population?
Answer:
The changes occurring in the peppered moth population is one of the most important studies which show the Darwin's proposed phenomenon of natural selection.
Before the industrial revolution, very rare black peppered moth existed. There were mostly light-coloured peppered moths. The colour of moths at that time was best to help them escape from predators. They were able to blend in with light coloured lichens and tree barks and escape from their predators.
But with the industrial revolution, the colour of the trees became darker due to the emission of dust and other gases. With the passage of time, it was seen that the peppered moth began changing its colour into a dark type. The black coloured moths were better able to survive now, hence these type of moths reproduced and increased in population. Whereas, the population of the light coloured moths declined. It was also observed that the allele for dark colour was dominant over the light colour. Hence, the change of colour evolved rapidly.
