The answer is <u>fishes</u>. Fish are unique in the aspect that they are the only vertebrates that blood circulates directly from respiratory organs to body tissues without returning to the heart first.
Answer: Option B
Explanation:
Glycogen is a hormone which is used to regulate the amount of glucose in the blood. Insulin and glycogen are two hormones that helps in regulation of the blood glucose.
When there several hours of fasting then there is decrease in the level of glucose in the blood then the glycogen is produced to meet the required amount of glucose in the blood.

Explanation:
Believe it or not, _ENERGY_ within an ecosystem is not transferred back and forth between all levels. Energy begins with the SUN and flows in one direction to PRODUCERS to CONSUMERS and, finally, to DECOMPOSERS.
A FOOD WEB represents all the possible paths for energy to flow within an ecosystem, whereas a FOOD CHAIN represents just one path. When drawing a diagram of a food web, you always draw the arrow in the direction of ENERGY FLOW. For example, an arrow from a PRODUCER to a CONSUMER.
Organisms at all trophic levels eventually die. MICROORGANISMS such as bacteria and fungi, process the stored energy in dead plants and animals and transfer part of it to the soil that the plants will use as nutrients, and the energy cycle continues.
Innate: keratinized epithelium
stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )
Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.
Adaptive: immunoglobulin plasma cells agglutinin
helper t cells memory t cells cytotoxic t cells cd4+cells
t lymphocytes
Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
antonio is considering that since the spiders came first, it cannot have 'derived traits' from anything. spiders themselves are the ancestralspecies of the insects
