They both can be found in the same food chain, but they aren't directly related. A hawk is a tertiary consumer (top of the food chain) and grass is a producer (bottom of the food chain). The hawks survival depends on grass:
Grass feeds on nutrients from the ground → insects eat grass and flowes → bigger insects eat the smaller insects → field rats eat the insects → hawks eat the field rats.

Answer:
mechanical weathering:
ice wedging: does not change rocks composition: abrasion
chemical weathering:
oxidation: changes rocks composition: acid rain
En la respiración celular, la célula depende totalmente de las reacciones Redox, para ser precisos de la reducción del NAD a NADH y la oxidación de NADH a NAD.
Ahora veamos una situación diferente.
En la fotosíntesis, ocurre la reacción inversa de redox, como se muestra en la siguiente ecuación:
6CO2 + 6H2O + E --> C6H12O6 + 6O2
La energía biológica se almacena y se lanza con la frecuencia por medio de reacciones redox. La fotosíntesis implica la reducción del CO2 en azucares y la oxidación del H2O en oxigeno molecular (O2), mientras que en la respiración es lo inverso, la oxidación de azucares a CO2 y H2O.
Entre los pasos redox de la fotosíntesis, compuestos deducidos del CO2 reducen el NAD lo que crea entonces, la creación gradiente de protones, que conduce a la síntesis del ATP y es mantenida por la oxidación del O2.
En los seres vivos, el término redox se utiliza para describir el equilibrio NAD-NADH y NADP-NADPH.
El estado redox contribuye al equilibrio de los sistemas metabólicos. En el caso de alteraciones en las reacciones redox, puede producirse HIPOXIA, que es el déficit del O2 en la sangre, CHOQUE, que es el mal circulamiento de lal sangre y la SEPSIS.
Answers:
Hormones are chemical messengers....
Endocrine glands secrete hormones...
The pituitary gland plays...
is produced by the adrenal glands...
the gland will produce fewer amounts of the hormone...
produce chemicals called paracrine factors...
blood is called the thyroid.
Steroid hormones are synthesized from cholesterol, while nonsteroid hormones are synthesized from modified amino acids and small peptides. Non-steroid hormones are not lipid-soluble and therefore they need to bind to a receptor on a cell membrane; while steroid hormones can diffuse through the cell membrane.
Explanation:
Hormones are signaling molecules synthesized by glands. The endocrine glands include the adrenal glands, pineal gland, thyroid gland, parathyroid gland, pituitary gland, ovaries, testes, pancreas and hypothalamus. The pituitary gland is an endocrine gland that secretes hormones capable of stimulating the adrenal glands in order to produce steroid hormones. Hormone levels are often modulated by negative feedback, by which high-hormone levels reduce their own production. Paracrine factors (also known as growth and differentiation factors) are proteins that can diffuse across small distances in order to induce responses in neighboring cells. The thyroid gland secretes hormones involved in regulating metabolism and growth. Moreover, the thyroid gland also secretes calcitonin that regulates calcium levels in the blood.
Answer: Geography affects solar energy potential because areas that are closer to the equator have a greater amount of solar radiation.
Explanation: However, the use of photovoltaics that can follow the position of the Sun can significantly increase the solar energy potential in areas that are farther from the equator.
