Go Deep! Look at the Parent Chromsomes and Key pictured below. Would it be possible for these parents to have a daughter with Hemophilia?
Answers
Answer: No, the daughter will be a carrier only.
Explanation: Hemophilia is a sex-linked recessive disorder. The recessive gene is carried on the X chromossome. Males have only one X chromossome, while females have 2. So, for a male individual to have hemophilia, it only needs the recessive gene to be on the X chromossome. In a female, the disorder is expressed when both X chromossomes has the recessive gene.
In the Parent Chromossomes picture shown, the father's X chromossome doesn't have the gene for hemophilia and the mother is heterozygous for the trait, i.e., she carries the recessive gene.
A daughter will inherit an X chromossome from the father and an X chromossome from the mother.
In this family, the daughter will inherit the X with dominant gene H for the father and has a possibility of inheriting another dominant gene H or recessive gene h from the mother.
For the daughter to be hemophiliac, she has to inherit 2 recessive genes. Since in either case she won't, she only inherits 1 recessive gene, the daughter will be a carrier for the trait, not have the disease.

Answers
The compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.
What is the significance of compact bone?Compact bone is a dense, hard bone tissue that provides structural support and protection to the body, and it is also involved in the storage of minerals, such as calcium, which is important for the strength and density of bones. Haversian canals are present in the compact bone and contain blood vessels, nerves, and other tissues that support the bone.
Hence, compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.

Review the Protein to Trait Example. How did the differences in proteins lead to different traits for this feature?
Answers
Answer:
Proteins are responsible for shaping and growth of an organism.
Explanation:
The differences in proteins lead to different in traits because it is the protein that determines the trait. The gene's sequence is like language that instructs cell to manufacture a particular protein that is necessary for the growth and development of the organism. These proteins shaped the structure of organisms so we can say that difference in traits occur due to difference in their proteins.
S. If cells of onion peel and RBC are separately kept in hypotonic solution, what will take place? Explain the reason for your answer
Answers
Answer:
Well for the onion peel, since its a plant cell...it shall gain water from the solution as it has a lower water potentail,and hence increase in size, becoming turgid and tight, with the cell wall exerting pressure to stop it from bursting.
For the RBC, its an animal cell, and shall also gain water, but since there is no cell wall to support it, it shall soon gain so much water that it shall burst becuase of the pressure, through lysis, and shall die.
Note, the plant cell does not die.

If a student tested the bubbles collected in the test tube what would they find they are made of and how do you know?
Answers
Hello. This question is incomplete. The full question is:
A student prepared two beakers with identical sprigs of a water plant as shown below. She placed Beaker A in the shade and the Beaker B beside a fluorescent lamp. She then systematically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.
If the student later tested the bubbles collected in the test tube, What would she find they are made of?
Answer:
oxygen
Explanation:
The bubbles are oxygen and we can say that because this is the gas that plants release through photosynthesis. In this case, we can also confirm that the plant that was exposed to fluorescent light, showed more bubbles than the other plant, since the light allowed the photosynthetic rate of this plant to be higher, releasing more oxygen to the environment.

Answers
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
Negative feedbacksPositive feedbacksNegative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.

The correct option is (a) Phylogenetic classification uses genetics and ancestral relationships to classify organisms.
Phylogeny classifies species based on evolutionary kinship or evolutionary distance (taxonomy). The degree and type of evolutionary distance between organisms determines their phylogenetic connection. Let's define taxonomy in order to better comprehend this idea.The connection between classification and phylogeny?The study and comparison of traits as well as the comparison of groups of organisms are the foundations of both phylogeny and categorization. However, there is a distinct feedback between character interpretation and inferred phylogeny, which is seen in the weighting of the characters used to construct the classification.

Answers
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.
