In Bryophytes, the sporophyte is dependent on the larger gametophyte, whereas, in Angiosperm and Gymnosperms, the gametophyte generation is dependent on the larger sporophyte generation.
<h3>Difference between gametophyte and sporophyte.</h3>
- The gametophyte is the haploid(n) state in the life cycle whereas the sporophyte is the diploid(2n) state in the life cycle.
- Gametophyte leads to gamete formation whereas sporophyte leads to the formation of spores.
- Spore formation takes place post meiosis whereas gamete formation either occurs directly or through mitosis.
- The meiospore grows to develop into the gametophyte. The zygote grows to produce sporophytes
- The cells in sporophytes have two genomes or possess two sets of chromosomes. The cells of the gametophyte have a single genome or produce one set of chromosomes.

Answer:
The beaker has more water.
Explanation:
The beaker which has more water takes more time to reach the room temperature because it has more surface area than other one. If a body has less surface area then it will lose heat energy quickly and to reach its room temperature as compared to the body that has more surface area. Heat transfer depends on the materials in which it is placed and the surrounding environment. In some materials conduction of heat occurs quickly as compared to other materials.
Answer:
carbon-With four electrons that can be shared to make covalent bonds, carbon-based molecules display an enormous variety of size, shape, and properties.
Explanation:
This is false
This selection and variation happens more gradually. It is hard to notice over a short period of time. The change is slow, constant and consistent. In punctuated equilibrium, the changes come in spurts. There are periods wherein a huge change occurs and there are also periods with very little change. The mutation is at random. Genetic drift is the change in the frequency of a gene variant due to a random sampling of organisms.
The chance of the offsprings with stripe on head is 50%.
Option A.
<h3><u>Explanation:</u></h3>
Here according to the figures, the male is the brown one which has no stripe on his head as mentioned, and the female is the pink one who has a stripe on her head. The gene for the head stripe is denoted by H.
So the genotype of the father which is given as Hh. He is heterozygous.
The genotype of the mother should be hh as she has stripe and she must be homozygous recessive to have it.
So the gametes from father is H and h. Whereas the gametes from mother is only h.
So the genotype of the offsprings are Hh and hh as 50% each.
So the probability of the offspring being striped head is 50%.
