Answer:

Explanation:

The main difference between intermolecular and intramolecular forces is that intermolecular forces exist between the molecules themselves, whereas intramolecular forces exist between atoms within a molecule. Intermolecular forces are formed between molecules and, intra-molecular forces are formed within the molecule. • Intra-molecular forces are much stronger compared to intermolecular forces.

soldier1979 [14.2K]

Answer:

OH, H2O2 and O−2

Explanation:

Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.

More blood vessels are stimulated to ______ more than ______ because blood vessels contain more ______ receptors than ______ rec

serg [7]

More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.

<h3>What is Vasoconstriction?</h3>

This is the process which involves the narrowing of the blood vessels through their muscle wall.

They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

On the lines provided, enter the name of the target organ(s) affected by the pituitary hormone indicated. Hypothalamic nerve cal

Dennis_Churaev [7]

Produced by the anterior pituitary. It's regarded as a tropical hormone. Target cells are impacted by tropical hormones indirectly after being stimulated.

<h3>The anterior pituitary gland affects which organs?</h3>

The following organs, glands, and bodily tissues are affected by and interact with the anterior pituitary hormones: organs, muscles, and bones the growth hormone (GH). Adrenocorticotropic hormone: Adrenal gland (ACTH). thyroid hormone, which stimulates the thyroid gland (TSH).

<h3>What are the anterior pituitary gland's seven hormones?</h3>

Frontal pituitary

hormone adrenocorticotrophic (ACTH)

hormone that stimulates the thyroid (TSH)

Luteinizing agent (LH)

hormone that stimulates ovulation (FSH)

Prolactin (PRL) (PRL)

hormonal growth (GH)

MSH, or melanocytic-stimulating hormone

Because it releases hormones that regulate the thyroid, adrenal glands, ovaries, and testes, the pituitary gland is frequently referred to as the "master gland."
