Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
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 development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.

what is mutation? why are mutations more serious when they occur in a sex cell?
Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.

what is the relationship between exposing to a virus and developing immunity to it? cite evidence from the text to support your response
Answer:
Exposure to a virus is closely related to the development of immunity, since the immune system is responsible for creating antibodies in response to the presence of potentially harmful biological agents, such as these viruses.
Explanation:
Viruses are biological agents that can produce diseases when they enter the body of a living being. In response to contact with a virus, the immune system synthesizes specific antibodies to combat the foreign biological agent.
Antibody immunity can be of two types. It is fast when it is mediated by immunoglobulins M (IgM), which attack the virus anywhere, while the late and prolonged response is due to the development of immunoglobulins G (IgG).
An example of immunity to a virus occurs with the exhibition to the virus of the Dengue, that creates permanent immunity to the viral serotype to which an individual is exposed.
The acquired immunity, mediated by antibodies, is the base for the development of vaccines.

While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?
O Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
O Cells with mutations outnumber and consume normal cells that do not have mutations,
O A mutation can attack a cell's DNA and cause an autoimmune response in the cells.
+
O Mutations cause cells to become unable to divide and the cells die in masses, forming tumors.
Answer:
Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
Explanation:
Answer:
The answer is "A."
Explanation:
Cancer develops when the cells in the body are constantly dividing uncontrollably. In humans, cancer is often the result of a negative mutation genetically. The other answers are wrong and do not match the way cancer forms. So, A will be your answer.

Why is knowing information about embryo development important?
Answer:
It helps you understand how life forms and what it takes for life to develop as well as the changes through this life cycle
Explanation:
Knowing information about embryo development is important because it helps us to understand how an organism grows and develops from a single cell into a complex being.
Why knowledge about embryo development important?An embryo is the stage of development that follows fertilization and begins when the zygote, a single cell formed by the union of a sperm and egg, begins to divide and differentiate into the various cell types that will make up the organism.
This knowledge can be used in various fields, such as reproductive medicine, to help improve fertility treatments and increase the chances of successful pregnancies. It can also be used in fields such as genetics and evolutionary biology to understand how traits are inherited and how species have evolved over time. Understanding embryo development can also provide insights into the causes of birth defects and developmental disorders, and help researchers develop treatments or interventions to improve the health and well-being of individuals.

Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.

Three terms used to describe organisms such as cows are:
MammalsHerbivoresRuminantsWhat is an organism?An organism, especially a cow, is a living thing. An organism is a singular living being that exhibits characteristics of life, such as the ability to develop, reproduce, respond to stimuli, and preserve homeostasis. Mammalia, a class of multicellular organisms including cows, forms the animal kingdom. Cows are complex biological entities with specialized sensory and digestive systems that enable them to live and thrive in their environment.
The following three terms are used to describe cow-like creatures:
Cows are mammals, which are warm-blooded animals with hair or fur and the ability to feed their young with milk.
Herbivores: Cows are herbivores, which means they only eat plants and no animal products like meat or dairy.
Cows are included in the class of herbivorous mammals known as ruminants, which have a four-chambered stomach.
