Answer:
The correct answer is explained below:
Explanation:
- According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
- It produces the following gametes: TA, Ta, tA, ta.
- The heterozygous tall, terminal plant has the following genotype: Ttaa
- It produces the following gametes: Ta, ta.
- Crossing them,
TA Ta tA ta
Ta TTAa TTaa TtAa Ttaa
(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)
ta TtAa Ttaa ttAa ttaa
(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)
- The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
- The phenotypes obtained are:
- Tall, Axillary = 3.
- Tall, Terminal = 3.
- Short, Axillary = 1.
- Short, Terminal = 1.
If the beavers need large teeth to collect wood for their dams, the population of beavers with larger teeth will live longer because they can collect wood. They will them be able to reproduce therefore passing down the gene with larger incisor teeth
Answer:
A
Explanation:
there will be a decrease in the number of crustaceans witch will cause a decrease in the fish population.
The Spanish scientist should bear in mind that the production of eggs of salmon is dependent on lots of factors apart from the temperature. These factors include type of water, nutrients, etc. If these factors are also set constant then, the scientist can expect the same result from his friend.
Answer:
This traumatic pathology occurs in children because the concentration of minerals is lower in children, since these have a greater collagen fibrillar organic structure, which is what gives children greater elasticity during bone growth until the areas close. proliferative.
The denomination in green stem comes from the analogy between this type of fracture and the one that occurs when trying to break the green stem of a plant.
It is characterized by being an incomplete fracture, with rupture of the periosteum and cortical bone on the convex side of the bone, while in the concave area the periosteum does not break, as a consequence the bone is not completely broken (incomplete fracture), but the fragments move and present an angulation of variable amplitude that needs to be corrected
Explanation:
To be more specific, these fractures occur more up to ten years of age, according to some research.
The centers of bone proliferation and differentiation where osteochondral mineralization of long bones occurs is what confers greater flexibility and greater organic content in the long bones of children.
