Complete question:
___BLANK___ system contains glands that secrete hormones into the bloodstream, whereas the ___BLANCK__system secretes substances through ducts.
Answer:
The ENDOCRINE system contains glands that secrete hormones into the bloodstream, whereas the EXOCRINE system secretes substances through ducts.
Explanation:
Those tissues that produce hormones might be classified as:
- endocrine glands (produce hormones exclusively),
- exocrine glands (produce hormones and other secretions),
- non-glandular tissues that secrete hormones but are not glands.
- Endocrine organs, also known as ductless glands or endocrine glands, release their secretion directly to the bloodstream. Blood transport hormones to target cells, tissues, and organs, where they stimulate a change in metabolic activities
- Exocrine glands release their secretions to a duct of different tissues where they act, such as the internal or external surface of cutaneous tissues, stomach mucose, or pancreatic ducts.
Answer: I think it is methanogenesis.
Explanation:
Answer:
smooth was dominant over that for wrinkled
Explanation:
In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.
Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
