Answer:

Explanation:Arthropods are characterized by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. The rigid cuticle inhibits growth, so arthropods replace it periodically by moulting. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. Some species have wings.

Their versatility has enabled arthropods to become the most species-rich members of all ecological guilds in most environments. They have over a million described species, making up more than 80 percent of all described living animal species, some of which, unlike most other animals, are very successful in dry environments. Arthropods range in size from the microscopic crustacean Stygotantulus up to the Japanese spider crab.

GenaCL600 [577]

Answer:

Heterozygous A: AO (remember, O type blood is a recessive allele. It's masked by A)

Heterozygous B: BB (h0m0zygous)

AO x BB --> AB, BO

Therefore, the genotypes of their offspring will be 1 AB to 1 BO, while the phenotypes will be 1 AB blood to 1 B blood.

<h2>Specialists and Generalists </h2>

Explanation:

Niche is the role played by an organism that how it lives in an environment

Specialists

Species that have narrow niches are called specialists and this type of niche is called realized niche
It is narrow because of the presence of ecological barriers and is the space where a species actually lives

Generalists

Species that have broad niche are called generalists and this type of niche is called fundamental niche
It is larger than the realized niche due to absence of ecological barriers
It represents all the environmental conditions where a species is able to live or can live
