Answer:
Meninges
Explanation:
Meninges refer to the protective membranes that surround the brain. Dura mater is the outer most meninx which forms a tough and fibrous cover. Pia mater is the deepest meninx and represent the delicate layer of connective tissue. Present between pia mater and dura mater is the arachnoid mater. Together, dura mater, arachnoid mater and pia mater make a membranous encasement to cover the brain and protect it from any injury.
Answer:
Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.
Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.
Answer:
ALL the aerobic respiration produces about 36 ATP molecules.
Explanation:
First-hand smoke, which is inhaled by the smoker. Second-hand smoke, which is the smoke either exhaled by a smoker or released from the end of a burning cigarette.
The effects of tobacco smoke on the respiratory system include: irritation of the trachea (windpipe) and larynx (voice box) reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages.
since the levels of exposure to secondhand smoke are lower than in active smoking, the effects of secondhand smoke tend to be less severe. Non-smokers exposed to secondhand smoke commonly experience eye, nasal and throat irritation. Secondhand smoke may be responsible for causing the onset of asthma in adulthood, may contribute to increased airway wall thickness and poorer health outcomes. Research suggests that exposure to secondhand smoke may cause an elevated risk of developing chronic obstructive pulmonary disease (COPD), which is marked by permanent and progressive damage to the airways and airway sacs of the lung.
Secondhand smoke is extremely dangerous for babies. They’re also more likely than other children to develop a range of lung and other health problems. It weakens their lungs, asthma, makes them more prone to ear infections, and doubles the risk of sudden infant death syndrome.
Some of the health conditions associated with being exposed to second-hand smoke whilst pregnant are a miscarriage, low birth weight, early birth, learning or behavioural deficiencies in your child, and Sudden Infant Death Syndrome
Answer:The cell cycle a. includes mitosis as an event.
Explanation:
The cell cycle consists of two stages:
interface and phase M (mitosis). In the first, the cell grows and doubles its DNA; It consists of phases G1, G2 and S. In phase M, the cell divides its already duplicated DNA and the cytoplasm divides into 2 (cytokinesis), forming 2 daughter cells. There is a G ° phase, where the cell is in a "vegetative" state, called "senescence." The cell cycle is regulated cyclin / CDK complexes, tumor suppressor genes (example: p53).
