what would happen if a sex cell could not complete DNA replication?
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
examples of mutations in human genes that affect the phenotype?
Answer: Sickle-cell Anemia, Beta hemoglobin (beta globin)
Explanation: For example, sickle-cell anemia is a disease caused by the smallest of genetic changes. Here, the alteration of a single nucleotide in the gene for the beta chain of the hemoglobin protein (the oxygen-carrying protein that makes blood red) is all it takes to turn a normal hemoglobin gene into a sickle-cell hemoglobin gene. This single nucleotide change alters only one amino acid in the protein chain, but the results are devastating.
Beta hemoglobin (beta globin) is a single chain of 147 amino acids. As previously mentioned, in sickle-cell anemia, the gene for beta globin is mutated. The resulting protein still consists of 147 amino acids, but because of the single-base mutation, the sixth amino acid in the chain is valine, rather than glutamic acid.
Sickle-cell anemia is an example of a mutation in the beta-globin gene that changes the phenotype of a red blood cell.
What is Mutation?Genetic alterations might result in a condition like sickle-cell anemia. Here, a normal hemoglobin gene may be converted into a sickle-cell hemoglobin gene by changing a single nucleotide in the gene encoding the beta chain of the hemoglobin.
A single chain of 147 amino acids makes up beta-globin, often known as beta-hemoglobin. The beta-globin gene is mutated in sickle-cell anemia, as was already noted.
The resultant protein still has 147 amino acids, but due to the single-base mutation, valine rather than glutamic acid makes up the sixth amino acid in the chain.
Therefore, only one amino acid in the protein chain is altered by this one nucleotide mutation, but the consequences are disastrous.

Biomagnification: Hidden Dangers in Food
Webs
Answer:
rfrg
Explanation:
Biomagnification is the process by which toxins and pollutants become increasingly concentrated in the bodies of animals as they move up the food chain. This means that organisms at the top of the food chain, such as humans, can end up with dangerously high levels of these pollutants in their bodies if they consume contaminated prey.
When does this phenomenon is concerning ?This phenomenon is particularly concerning when it comes to certain toxins, such as mercury and persistent organic pollutants (POPs) like PCBs and DDT. These toxins can have serious health consequences, including neurological damage, developmental delays, and cancer.
One example of biomagnification in action is with mercury contamination in fish. Mercury is released into the environment through various human activities, including burning coal and waste incineration. When this mercury enters waterways, it can be transformed into methylmercury, a highly toxic form that accumulates in the tissues of fish and other aquatic organisms.
As larger fish consume smaller fish, the concentration of methylmercury in their bodies increases, leading to dangerously high levels in the bodies of top predators like sharks and swordfish. When humans consume these contaminated fish, they can also accumulate dangerous levels of methylmercury in their bodies.
Similarly, POPs like PCBs and DDT can enter the food chain through contaminated soil and water. As these toxins move up the food chain, they become increasingly concentrated in the bodies of top predators like birds of prey and mammals like seals and polar bears.
These toxins can have serious health consequences for these animals, including reproductive problems and weakened immune systems. When humans consume these contaminated animals, they can also accumulate dangerous levels of these toxins in their bodies.
Biomagnification is a serious issue that highlights the importance of careful monitoring of environmental pollutants and the need for sustainable practices to prevent contamination in the first place.

25m/s in 5 seconds. What is its acceleration?
+25m/s2
+5m/s2
-Om/s²
5m/s
Answer:
B) 5m/s^2
Explanation:
The formula for acceleration is [tex]\frac{vf-vi}{t}[/tex]
vf is the final velocity which in this question is 25m/s
vi is the initial velocity which in this question in 0m/s because it says "A stopped car"
t is the time which is 5 seconds
When you put these numbers into the formula you get 5m/s^2

State TWO characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants . Explain how EACH characteristic makes the respiratory surface suitable for gaseous exchange .
Answer:
Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Respiratory surfaces in both human beings and plants have several characteristics that are peculiar and similar to each other. There are some requirements to be met for gaseous exchange to occur.
Two characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants include ---
1. Respiratory surface must be thin and allow for rapid diffusion.
2. These surfaces must be in contact with air or fluid.
Respiratory surfaces in plant living cells in the stem are organized in thin layers close to the surface.Their loose packing ensures air spaces where they are in close contact with the airflow either in or out. In humans, the respiratory surface is thin allowing for rapid diffusion of oxygen in and CO₂ out. They are also always in contact with the bloodLearn more: https://brainly.com/question/9128660

Which is a tertiary consumer in this food web?
Answer:
Look below.
Explanation:
A tertiary consumer is an animal that eat primary consumers and secondary consumers. From this knowledge we can conclude that the tertiary consumer is the mountain lion since nothing consumes the animal and it is on the top of the food web for consuming the most energy.
Answer:
The Mountain Lion
Explanation:
In a food web the arrows indicate energy being transferred to the animal it's pointing to from the animal it's pointing away from. In other words the arrow points at the animal that ate the one it is pointing away from. Since the Mountain Lion has the most arrows pointing to it, it's the highest predator in this food web. Since it is at the top it is a tertiary consumer.

Do living things go through mitosis? Justify your answer
Answer:
Yes
Explanation:
mitosis is how more cells are created that are genetically identical to the parent cell. it's essential to growth and repair
All living organisms are able to reproduce and produce offspring, where as eukaryotic organisms that includes aquatic plants and algae, which proliferate through the process of mitosis. Mitosis is the process in which a cell divides into two cells.
What is Mitosis?Mitosis is defined as the process of cell division in which chromosomes are duplicated and equally distributed into two daughter cells where each daughter cell has the same number of chromosomes as the parent cell, i.e. diploid. Hence, mitosis is known as equivalent division.
The mitosis process, which produces two identical nuclei/daughter cells, has four phases: prophase, metaphase, anaphase, telephase. Mitosis in the cell cycle is preceded by the G2 phase where metabolic changes assemble the cytoplasmic materials needed for mitosis and cytokinesis and the metabolic changes that occur after the G1 phase prepare the cell for division.
Thus, all living organisms are able to reproduce and produce offspring, where as eukaryotic organisms that includes aquatic plants and algae
