Explanation:
compare and contrast the processes of mitosis (asexual reproduction) and meiosis (sexual reproduction).
Answer:
Diffrence:
Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.

What is speciation ? List four factors that could lead to speciation. Which of tjese cannot be a major factor in the speciation of a self-pollinating plant species? Explain. Give reason to justify your answer.
pesto ica está.
➜ Speciation is the formation of new species from the pre-existing population.
Factors responsible for speciation:
Genetic drift. Natural selection.Geographical isolation. Mutation.Geographical isolation cannot be a major factor in the speciation of a self-pollinating plant species because physical barrier cannot be created in self-pollinating plants.
Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

__________ is a method of studying complex systems by reducing the components that are studied (e.g. studying cells in culture and using those results to understand what is going on in a complex disease).
Select one:
a.
emergent properties
b.
systems biology
c.
genomics
d.
reductionism
Answer: A.
Explanation: "An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood. You will need the whole heart to be able to pump blood."
Explanation for the incorrect answer:
"Systems biology is the computational and mathematical analysis and modeling of complex biological systems. It is a biology-based interdisciplinary field of study that focuses on complex interactions within biological systems, using a holistic approach to biological research. "

What is keeping Northern Europe from freezing? * 1 point O Warm water from the south is being carried across the North Atlantic Warm water from the south is being carried along the equator Cold water is coming south from the arctic Cold water is rising along the African Coast
Answer:The ocean is constantly in motion, moving water from place to place via currents. The Gulf Stream brings warm water from the Gulf of Mexico all the way up to the Norwegian Sea. As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.

Crossing over occurs at the ends of chromosomes, rather than near the centromeres. As a result of crossing over, sister chromatids are no longer identical to each other. For crossing over to occur, homologous chromosomes must align precisely early in prophase I so that nonsister chromatids can exchange corresponding segments of DNA. Crossing over prevents homologous chromosomes from separating during meiosis I.

Explain the relationships and trade-offs among amounts of skin pigmentation, Vitamin D production, and protection from UV radiation.
Answer:
Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D
Explanation:
Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.
