4Prolactin
Prolactin hormone allows a woman to produce milk after she gives birth. Thus, the correct option is D.
What is lactation?Lactation is the process of producing and releasing milk from the mammary glands in breasts. Lactation begins in pregnancy when hormonal changes signal the mammary glands to make milk in preparation for the birth of baby.
It’s also possible to induce lactation without a pregnancy using the same hormones that your body makes during pregnancy. Lactation ends once your body stops producing milk.
Milk ducts increase in size and number when levels of estrogen and progesterone rise. The result is a fuller breast. The mammary glands start to get ready to produce milk.

Why is it important for DNA to unwind before replication?
Responses
to expose bases so they can be paired with new bases
to improve flexibility in the DNA strand's phosphate backbone
to allow proteins to check for mistakes in the DNA strands
to prevent the new DNA from accidentally sticking together
Answer:
All
Explanation:
All of the responses in the selection are related to the importance of DNA unwinding before replication:
"To expose bases so they can be paired with new bases"
"To improve flexibility in the DNA strand's phosphate backbone"
"To allow proteins to check for mistakes in the DNA strands"
"To prevent the new DNA from accidentally sticking together"
Each of these factors plays a role in the overall process of DNA replication, and together they help ensure that the process occurs efficiently and accurately.
James Watson’s discovery of the base pairings in the DNA helix was a result of trial and error.

What are the characteristics of DNA double helix?A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
To avoid bumping into each other, the staircase has to twist a little bit. This turns our staircase into a spiral staircase. This extra twist at the end is the reason for the helical shape. For the “steps” of the DNA “staircase” to fit together, they have to twist a little bit.

chromatids segments exchange, forming a chiasma. unselected two of the chromosomes carry new combinations of genes. unselected the chromatids forming the chiasma break, and the broken-off ends join their corresponding homologous. unselected chromosomes synapse during prophase of meiosis i.
The correct answer is Exchanges of DNA segments between sister chromatids of a duplicated metaphase chromosome are known as sister chromatid exchanges (SCEs).
The chiasma is a structure that develops through crossover recombination between a pair of homologous chromosomes and physically connects the homologous chromosomes during meiosis. When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the formation of egg and sperm cells (meiosis). The beginning of meiosis I is preceded by DNA replication. Homologous chromosomes link up and create synapses during prophase I, a process that only occurs during meiosis. The paired chromosomes are known as bivalents, and it is now clear that genetic recombination is what causes chiasmata to occur.

Which is an example of an adaptation?
A. bald spots on an old cougar
B. new foods found by squirrels
C. viruses passed to humans
D. white hair of adult polar bears
The correct answer is D. White hair of adult polar bears
Explanation:
Adaption refers to a natural process that involves a change in behavior or traits in a species or population to make this more suitable to survive. Indeed, adaptations help an organism to survive in a specific environment or adapt to changes. Besides this, adaptation is the result of processes such as natural selection through which more fit organisms survive and pass fitness traits to new generations.
According to this, the one that is an example of adaptation is the "white hair of adult polar bears" because this phenotype (visible trait) helps polar bears to camouflage in the Artic, in this way, polar bears can avoid possible predators and have more chances to hunt. This means, this trait makes polar bears more suitable to survive and due to this, it is an adaptation.

What was the climate like prior to the extinction ?
Answer:
The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

hope this helps! <3
Dr. Jones says an atom has three electrons in the first shell and four electrons in the second shell. Someone should tell Dr. Jones that the second shell can't have four electrons, which is in option B. So, option B is the correct answer.
The electron configuration of an atom is determined by the way electrons are distributed in its energy levels, or electron shells. The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8 electrons. According to the information provided by Dr. Jones, there is an error in the electron configuration. If an atom has 3 electrons in the first shell and 4 electrons in the second shell, that configuration is not possible based on the rules of electron distribution. The second shell cannot have 4 electrons; it can accommodate a maximum of 8 electrons. So, option B is the correct answer.

5. CER: How does all the activities that we have done in this unit so far (Here Today,
Peppered Moths, Fork Birds and Unicorn Island) support Darwin's theory of
natural selection? Give examples in your description. (This is not a short answer)
Answer:
Explanation:
Charles Darwin's theory of natural selection proposes that in a given population, individuals that possess advantageous traits have a better chance of surviving and reproducing, passing down these beneficial traits to their offspring. The activities in this unit, including Here Today, Peppered Moths, Fork Birds, and Unicorn Island, all provide evidence to support Darwin's theory.
Here Today is a simulation that models the process of natural selection. In this activity, students play the role of predators and prey in a simulated ecosystem. The predators have a higher chance of survival if they are better adapted to the environment, and the prey have a better chance of survival if they possess advantageous traits such as speed or camouflage. This activity demonstrates how advantageous traits are naturally selected over time as they confer a greater chance of survival.
Peppered Moths is a classic example of natural selection in action. The activity explores how changes in the environment, such as the increase in pollution during the Industrial Revolution, can have a significant impact on the survival of a species. The dark-colored moths had an advantage in the polluted environment, as they were better camouflaged against the soot-covered trees, and were therefore less likely to be preyed upon. This led to an increase in the proportion of dark-colored moths in the population, demonstrating how natural selection can result in a shift in the genetic makeup of a population over time.
Fork Birds is another simulation that models natural selection. In this activity, students play the role of birds that must compete for food resources. The birds with longer beaks are better adapted to extract food from deep crevices, while birds with shorter beaks can more efficiently extract food from shallow crevices. This activity demonstrates how natural selection can favor different traits depending on the environmental conditions and the available resources.
Unicorn Island is a fictional simulation that explores the process of natural selection in a fun and engaging way. In this activity, students design their own unicorns with different physical traits and compete against each other in a virtual ecosystem. The unicorns with advantageous traits, such as wings or strong horns, have a better chance of surviving and passing down these traits to their offspring, while unicorns with less advantageous traits are less likely to survive.
In conclusion, the activities in this unit all support Darwin's theory of natural selection by providing examples of how advantageous traits are naturally selected over time, resulting in a shift in the genetic makeup of a population. These activities demonstrate how natural selection operates in a variety of different contexts, from simulated ecosystems to real-world examples of environmental change.
