Korvikt [17]2 years ago
7 0

Answer:

1.Two products are obtained as a result of double fertilization.

2 There are chances of polyembryony, and the plant has better chances of survival.

3.Double fertilization gives rise to an endosperm that provides nourishment to the developing embryo.

4.It increases the viability of the seeds of angiosperms.

5.It utilizes both the male gametes produced by the pollen grains.

All of these species are herbivores and share the same habitat. Coexistence, however, can occur when animals partition their nic
Alona [7]

Answer:

  • Eating different vegetables.
  • Eating at different times.
  • Eating in different places in the same region.

Explanation:

It is common for herbivorous animals of different species to share the ecological niche and the same habitat without establishing competition for resources. In this case, these animals manage to maintain a balance between their populations and the resources available for both species to survive. Three ways of doing this are:

  • Feeding on different vegetables: Even though they are herbivores, some animals prefer a specific type of vegetable, or just feed on these vegetables. We can use as an example animals that eat only fruits and animals that eat only herbs.
  • Eating at different times: Some animals have nocturnal habits, while others have diurnal habits. This is very efficient so that these animals are not competitors and are able to feed at different times
  • Eating in different places in the same region: We can use as an example two species of turtles, where one lives on the south side of the region and feeds on the vegetables found there, while the other species lives on the north side of the region and feeds on vegetables found there.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color
Gnom [1K]

Answer:

2001

Explanation:

This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.

According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1

1. Plant height 787 tall 277 short (3:1)

2. Flower color 705 purple 224 white (3:1)

3. Flower position 651 middle of stem 207 end of stem (3:1)

4. Pod color 428 green 152 yellow (3:1)

5. Pod shape 882 inflated 299 constricted (3:1)

6. Seed color 6,022 yellow X green

7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)

This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio

Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001
