Answer:
Blood Type Pedigree Mystery Lab Activity In this lab activity, students will solve a theft crime using their knowledge of pedigrees and the inheritance of traits (like ear lobe attachment and blood type) to create a pedigree of a mystery family. They will then determine the genotypes of the family members in order to identify the thief.
Explanation:
In a family, the inheritance pattern of blood type can be represented with a pedigree. Blood type pedigrees are used to make different interpretations according to the question.
Since I do not have the complete question, I will provide information about blood type inheritance and pedigrees for you to interprete or to construct a Blood type pedigree.
What is the ABO blood type?ABO blood type refers to the classification of the blood according to the antigens present.
The I gene determines the blood type of a person. It is a three-allelic gene that expresses complete dominance and codominance.
IA and IB alleles are dominant over the recessive i allele.→ IA dominant over i. The person presents A type of antigens.
→ IB dominant over i. The person presents B type of antigens.
→ i is the recessive allele. The person does not present any antigen.
IA and IB are codominant. The person presents both types of antigens, A and B.Genotypes
H0m0zyg0us dominant or heter0zyg0us Individuals IAIA or IAi will express the A blood type. H0m0zyg0us dominant or heter0zyg0us Individuals IBIB or IBi will express the B blood type Individuals with h0m0zyg0us recessive genotype, ii will express the 0 blood type. Individuals carrying IA and IB alleles will express the AB blood type.
What is a pedigree?
A pedigree is a representation of familiar history through generations.
This representation uses different symbols and numbers to identify individuals and generations.
It is usually used to follow the inheritance pattern of a certain trait or affection.
For a correct interpretation of a pedigree, we need to know that,
• Family members
→ Individuals are represented with geometrical figures.
→ Males are squares
→ Females are circles
→ Unborned individuals are rhombus
→ Individuals can be identified with numbers, letters, or names
• Trait/Phenotype
→ Empty figures represent Healthy/normal/not affected individuals
→ Solid black fgures represent Affected/mutated individuals
• Generations
→ Each file is represented with a roman number, indicating the Generation.
Knowing about the inheritance pattern of blood type and how to represent it in a pedigree, you can make different interpretations according to your question.

Imagine that you are a genetic counselor working with the first daughter in the last generation of the pedigree shown. She is married to a man with no history of ald in his family. The couple plans to have children and they want to know the chance of their first child having ald. How will you advise them?.
The chance of your first child having ald is 25%.Becose the adl gene may be recessive in this family.
How to advise them on family genetics?Recessive genes produce proteins considered “defective” as they become inactive. That is, they are hidden (recessive) with the presence of a dominant gene manifesting their characteristics in the absence of their dominant allele. The adl gene may be recessive in this family.
With this information, we can conclude that the chance of your first child having ald is 25%.

Apply your understanding of how living organisms use energy to argue in favor of why it is either beneficial or detrimental for cells to use ATP rather than directly using the energy stored in the bonds of carbohydrates to power cellular reactions.
a. ATP is readily available in the form of a single unit that provides a consistent, appropriate amount of energy. If cells harvested energy from various carbohydrate compounds, they would need to tailor each reaction to each energy source.
b. ATP energy cannot activate the ROS dependent stress response whereas food molecules are responsible for activating ROS.
c. ATP is low in energy, but food molecules (in the form of carbohydrates) possess higher levels of energy that cells can use.
d. ATP is readily available to cells, unlike the carbohydrate compounds that have to first be phosphorylated in order to release their energy.
Answer:
ATP is readily available in the form of a single unit that provides a consistent, appropriate amount of energy. The cell would need to tailor each reaction to each energy source if it harvested energy from different compounds.

The food chain and food web serve as conduits for the energy flow. Plants, who are the primary energy producers in an ecosystem.
What is the mechanism of energy flow in an ecosystem?The autotrophs that absorb energy from the sun are an excellent example of how energy moves through an ecosystem.
Utilize their chloroplasts to accumulate sunlight, which is then partially altered into chemical energy during photosynthesis.
Herbivores eat the autotrophs thereafter, converting the plant's energy into fuel for themselves. Then, carnivores consume the herbivores, followed by other carnivores consuming the carnivores.
Therefore, energy flow in an ecosystem is connected by different trophic level.

4.)Sexual reproduction produces more o
offspring than asexual reproduction.
Answer:
2) Asexual reproduction is a simpler process than sexual reproduction.
Asexual reproduction is a simpler process than sexual reproduction is a true statement.
What is Asexual reproduction?Asexual reproduction refers to a form of reproduction that excludes the joining of gametes or sex cells. Asexual reproduction does not require the mating of male and female gametes, as sexual reproduction does, in order to produce children.
The creature may reproduce even in the absence of a mate, producing young that are typically clones of their parents. Binary fission, budding, vegetative reproduction, spore formation (sporogenesis), fragmentation, parthenogenesis, and apomixis are the several asexual reproduction processes.
Asexual reproduction is a process used by bacteria, archaea, many plants, fungi, and certain mammals.

When pathogens are ingested by the macrophages and dendritic cells of the immune system, they are digested and a small portion of the pathogen, __________, is attached to the surface of the macrophage.
Answer:
Antigen
Explanation:
on the surface of the pathogen that helps immune cells identify then
When pathogen are swallowed by the immune system's macrophages and dendritic cells, they are digested and a small amount of the pathogen's antigen is attached to the macrophage's surface.
What is antigen?
Any chemical that triggers the body's immune system to react negatively to it. Toxins, chemicals, germs, viruses, and other things originating from the outside of the body are examples of antigens.
In reaction to exposure to antigens, B cells of the immune system create Y-shaped proteins known as antibodies (immunoglobulins).
Antigen receptors, such as antibodies and T-cell receptors, are responsible for recognizing antigens.
Immune system cells produce a variety of antigen receptors, giving each cell a specificity for a single antigen.
Therefore, antigen is attached to the surface of the macrophage.

Which organism exhibits behavioral adaptation?
- an owl with large pupils and eyes that enable it to see better at night.
- A possum playing dead to increase its chances of survival.
- An insect that mimics it’s environment to hide from its predators.
- A desert plant that sheds its leaves to lessen water loss during the dry season.
Answer:
B
Explanation:
a possum playing dead to increase its chances of survival
All of the options provided involve some form of adaptation, but the one that specifically involves behavior is the possum playing dead to increase its chances of survival. Hence option B is correct.
What is Behavioral adaptation?Behavioral adaptation refers to changes in an organism's behavior that help it to better survive and thrive in its environment. Playing dead, or "playing possum," is a behavioral adaptation that some animals, including possums, use when they feel threatened.
By playing dead, the possum is essentially trying to fool its predator into thinking that it is no longer a threat or a viable prey item. This behavior can increase the possum's chances of survival by deterring predators and allowing it to escape unharmed.
Other examples of behavioral adaptation include migration, hibernation, and communication between members of the same species. These behaviors can help organisms conserve energy, avoid harsh environmental conditions, and increase their chances of finding a mate or resources for survival.
Hence option B, A possum playing dead to increase its chances of survival is correct.
