Delicious77 [7]

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:
  1. Tall, Axillary = 3.
  2. Tall, Terminal = 3.
  3. Short, Axillary = 1.
  4. Short, Terminal = 1.

A chemical bonding tells what​
Vinvika [58]

A chemical bonding is a lasting attraction is atoms molecules or ions.There are three main types of bonds: ionic, covalent and metallic. These bonds occur when electrons are transferred from one atom two another, and are a result of the attraction between the resulting oppositely charged ions. This happens between atoms with an electronegativity difference generally larger than 1.8.

Colder climates promote higher biodiversity because they are usually larger in size. This provides space for more organisms.
Sergeu [11.5K]

Answer:

False  

Explanation:

The relationship between climate and biodiversity can be defined as follow: warmer climates are generally associated with higher biodiversity because these conditions promote the life of primary producers such as those organisms that produce organic compounds using simple substances and energy from light. Primary producers form the basis of the food chain, thereby their presence is fundamental to generate sustainable high biodiversity environments. For example, warmer climates such as tropical ecosystems promote plants (i.e., primary producers) to grow year-round, thereby supporting more organisms (i.e., species richness) that rely on plants.
