d. when the mutation is harmful
B. homozygous
C. petit
D. queue
The correct option is B.
Chromosomes can be classified as either homozygous or heterozygous based on the similarities between two alleles. A homozygous chromosome refers to a chromosome that have identical alleles on both homologous chromosomes. When the trait is dominant, it is represented by two capital letters; when the trait is recessive, it is represented by two lower case letters.
When the identical alleles are present on two chromosomes for a particular trait, the chromosomes are said to be homozygous.
Further Explanation:
The extent to which the genetic sequence of both the copies of a gene is the same is called zygosity. It can also be considered as the percentage of similarity the alleles have in an organism. The eukaryotes are mostly diploid in nature which implies that they contain chromosomes in a matching pair. In a diploid organism, the homologous chromosomes are present on the same loci but the two chromosomes can differ in the sequences at the loci. When both the alleles are the same in a diploid organism, then the organism is said to be homozygous. On the other hand, if the alleles differ in the nucleotide sequence, they are called heterozygous.
Different individuals have different DNA sequences for the same gene. These differences in the sequences form different forms of the same gene called alleles. Some genes have just one allele as any deviation in the allelic sequence might be fatal, while some other genes have more than one allele. The frequency of these alleles varies among a population. Two alleles might have an equal distribution in the population or one allele might be very common, making the other allele rare. The alleles are inherited from each parent which pair up in the zygote. The zygosity describes whether the two alleles are the same or different in their DNA sequences.
When two chromosomes contain the same copies of the alleles, they are called homologous chromosomes and the organism is termed as homozygous. An individual can be homozygous-dominant or homozygous-recessive depending on whether it has dominant or recessive copies of the alleles. The homozygous-dominant individual will express the dominant phenotypic traits while the individual who is homozygous-recessive will have a recessive trait.

Correct answer: A) Organisms gradually change the environment
Succession occurs when there is a disturbance in the environment, it would be a minor disturbance like a fire or a major disturbance like a volcanic eruption. Based on the disturbance, succession can be divided into two types:
1). Primary Succession: Primary succession is said to happen when a group of the species or a community evolve from a barren land or a land with no life. This land is fresh and does not have any life on it.
Example: Primary succession occurs after a volcanic eruption
2). Secondary Succession: The secondary succession is said to occur when there is a disturbance and it destroys ecosystem but still there is an availability of nutrient, seed, and soil.
Example: Forest Fire
Succession occurs because organisms gradually change the environment. (Option a.)
Succession is the process by which an ecosystem undergoes changes over time due to the influence of living organisms. It occurs because organisms gradually change the environment they inhabit. In ecological succession, there are two main types:
1. Primary Succession: This occurs in areas where no previous ecosystem existed, such as bare rock, volcanic lava, or newly formed sand dunes. Pioneer species, like lichens and mosses, are the first to colonize such areas. Over time, they break down the rock and create soil, making it possible for other plants and organisms to establish themselves. As the environment changes and becomes more hospitable, the community of species gradually changes, leading to a series of distinct stages until a stable climax community is reached.
2. Secondary Succession: This type of succession occurs in areas that have been disturbed or disrupted, but where soil and some remnants of the previous ecosystem remain. For example, after a forest fire or clear-cutting, the area will undergo secondary succession. Pioneer species, often grasses and shrubs, quickly establish themselves and create conditions for other species to colonize the area. As the ecosystem recovers, different stages of plant and animal communities succeed one another, eventually leading to a climax community that is relatively stable.
In both types of succession, organisms play a significant role in changing the environment, creating conditions that allow new species to establish and eventually leading to a more complex and diverse ecosystem.
