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.

Explanation:
Answer:
Loss of proprioception.
Explanation:
The hypothalamus is the small region located at the base of brain. The hypothalamus is divided into three main regions- anterior region, middle region and posterior region.
The hypothalamus plays an important role in maintaining the body's homeostasis. The sexual behavior and emotional response is regulated by the hypothalamus. Loss of proprioception is not maintained by hypothalamus as it is a neurological disease.
Thus, the answer is loss of proprioception.
The hypothalamus controls a range of bodily functions, and injury to it can disrupt aspects like hunger, thirst, temperature regulation, and sleep. However, it's unlikely to directly impair cognitive functions such as language and reasoning skills.
The hypothalamus is a region of the brain responsible for managing a variety of bodily functions, including hunger, thirst, body temperature, sleep, and emotions. Injury to the hypothalamus can lead to problems in these areas as well as hormonal imbalances. However, it won't directly cause an impairment in cognitive functions like reasoning or language skills, which are primarily regulated by different parts of the brain. Therefore, the injury to the hypothalamus may result in disruptions to eating, sleeping, and temperature regulation, but it is less likely to directly lead to a decrease in cognitive abilities.

age of trees
climate
precipitation
The correct answer is option B, Age of trees
The forest area is usually defined in terms of climatic condition prevailing with in it, the type of flora and fauna found, the area of the forest , its geography (including location, latitudes, nearby geographical features etc. ) and the geological conditions (soil type etc.). Age of the trees in its flora diversity is of no subsequent parameter to distinguish between two forest areas.
