Answer:
The peas with the purple flowers were dominant and the peas with the white flowers were recessive.
Explanation:
In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers. The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant. The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple. The flowers were only white if both alleles were for white flowers.
Answer:
1. Picky eating; food jag
2. epiphyseal plates
3. bone mineral density (BMD)
4. obesity
5. food insecurity
6. life expectancy
7. arthritis
8. congregate meal
Explanation:
Picky eating is a behavior in early childhood when they refuse to eat certain foods and only want the same foods, while food jag is when a child only eats a small group of foods, meal after meal. The epiphyseal plate is a specialized layer of hyaline cartilage where chondrocytes (i.e., the only cells found in healthy cartilage) proliferate and differentiate during longitudinal bone growth. Arthritis is an inflammation of the joints caused by different reasons (e.g., injury, genetic causes, infections, immune system dysfunction, etc), whose risk increases with age. Bone mineral density (also known as bone density), is the amount of mineral in bone tissues, being the best manner to measure bone health. Obesity can be defined as an excessive amount of body fat that presents a risk to health. Over the past 30 years, the prevalence of obesity has doubled in children and tripled in adolescents, representing a serious health problem (especially in developed countries). Moreover, food insecurity is a social condition of limited access to food for individuals in a household to live an active, healthy life, which can be used as a metric of how many people cannot afford food. Life expectancy is an estimation of the number of years a person can expect to live in a given country/region. Life expectancy around the world has increased for nearly 200 years especially due to medical progress and access to food. Finally, a congregate meal refers to a healthy meal provided to anyone age 60 or over that encourages older adults' social connections with other persons at the meal sites.
Hi,
I think the answer you're looking for is already in the question you submitted. However, I disagree that a frameshift could result from the mutation because frameshifts would only happen if there were insertions or deletions in the sequence. For your question, this is an example of a simple point mutation/nucleotide base substitution, and would only result to either a missense or a nonsense mutation. Depending on the bases flanking your mutation, this results to transcribing a different sequence of RNA leading to translating either a different amino acid or a stop codon.
Clotting cascade refers to the series of reactions which take place simultaneously and result in blood clotting. The clotting cascade is a complex set of negative feed back mechanism which is used by the human body to maintain homeostasis. The clotting cascade can be triggered either by intrinsic or extrinsic release of chemical mediators. The reaction occur in this order:
Intrinsic factor < activation of common clotting pathway < platelet lipids are released < prothrombin < fibrinogen < fibrin formation < stabilized fibrin clot.
Two examples of anticoagulant medication that affect the pathway are heparin and warfarin
not all but most of them do
