Answer:Prokaryotic cells make up the organisms found in the two Kingdoms of life known as Bacteria and Archaea.
there are cells without a nucleus, which are called prokaryotes. They are a group of organisms which lack a cell nucleus. The organisms with this type of cell are called prokaryotic organisms or prokaryotes. These organisms were the first to be found in the planet Earth.
A prokaryotic cell is mostly composed of a plasma membrane, cell wall, cytoplasm, genetic material in the nucleoid and ribosome. They are single-celled and are much smaller compared to eukaryotic cells. They exist in different shapes including spherical, rod, flat, coccus, spirochete, and some are also shapeless, not having a consistent shape.
Explanation:
Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.
Answer:
Option A
Explanation:
Option A shows the smallest building block of a living cell.
Answer: Endocrine
A chemical signal produced in the pituitary gland at the base of the brain binds to a receptor on liver cells. This signal would be classified as an endocrine signal.
Explanation:
An endocrine signal is produced by a cell that targets a distant cell through the bloodstream.
Hence, a endocrine signal (carried by hormones) produced at the base of the brain (usually an endocrine gland) travels through the bloodstream to the target cell and binds to a receptor on the liver, and then exerts its function.
