Answer:
Proteins are the internal machinery of a cell. Among the many different roles that proteins serve in the cell, proteins have structural roles to help the cell keep its shape, regulatory roles to control the movement of particles in and out of the cell, and repair roles to help signal and help with the repair of a cell if it is damaged. Proteins are especially important in cell division because they control when it starts, ends, and every movement in between.
1. The correct answer is A. Carbohydrates and fats are used for energy. For example, glucose, a monosaccharide carb, is used in cellular respiration to make energy.
2. It is not a carb or lipid as there is a Nitrogen. Your answer is Protein because it's showing an amino acid, the monomer of all proteins. There is an amine group, a carboxyl group, and R-Group. Therefore, it has to be C.
Gregory wants to make a hole in a flat piece of wood. He places object Y on the piece of wood, and then object X on top of it.(C) a screw and a wedge
Explanation:
Screw is used to drill a hole in the wood and the wedge is used to insert it properly.
The screw moves in a circular motion and thus creates a hole in the wood whereas a wedge is used to apply appropriate force on the screw .so that it can be placed properly in the wood.
The a screw and a wedge are termed as simple machines.Simple machines are those machines that we make use of to do day to day task at home.
So we can say that Gregory wants to make a hole in a flat piece of wood. He places object Y on the piece of wood, and then object X on top of it.(C) a screw and a wedge
Answer: The options were missing, but the endocrine organs that secret each gland are:
Pituitary gland: Thyroid-stimulating hormone
Pituitary gland: Adrenocorticotropic
Hypothalamus: Gonadotropic
Pituitary gland: Prolactin
Pituitary gland: Growth hormone
Thyroid gland: Thyroxine
Thyroid gland: Calcitonin
Thyroid gland: Triiodothyronine
Hypothalamus: Antidiuretic
Hypothalamus: Oxytocin
Adrenal gland: Glucocorticoids
Adrenal gland: Mineralocorticoids
Adrenal gland: Epinephrine
Pineal gland: Melatonin
Thymus gland: Thymosins
Pancreas: Insulin
Pancreas: Glucagon
Explanation:
- The pituitary gland, also known as the hypophysis, produces the thyroid-stimulating hormone, the adrenocorticotropic, prolactin, and growth hormone. The hypophysis has two parts, the anterior one and the posterior one. The anterior one secretes these hormones thanks to the action of hormones that comes from the hypothalamus.
- The hypothalamus, which is a gland that is in the brain, produces:
gonadotropic, antidiuretic, and oxytocin. Once produced, they are stored and secreted by hypophysis. In this case, these hormones are in the other portion of the hypophysis, the posterior part. The hormones act in the reproductive system.
- The thyroid gland, which is in the neck, produce and secretes:
thyroxine, calcitonin, and triiodothyronine. The calcitonin controls calcium concentration, while the thyroxine and triiodothyronine impact the cells' metabolism.
- The adrenal gland is above the kidneys. It secretes Glucocorticoids, Epinephrine, and Mineralocorticoids. The mineralocorticoids regulate the concentrations of water and salt in our body; glucocorticoids have many functions, one is fighting inflammation; lastly, epinephrine, also known as adrenaline, is released in a fight or flight reaction.
- The pancreas is an organ and a gland. As a gland, it secretes glucagon and insulin to regulate the concentration of glucose in the blood.
- The pineal gland is on the brain. This gland secretes melatonin, which is a hormone that helps us to sleep.
- The thymus gland is in the chest, and it produces a hormone called thymosin. This hormone helps in the production of leucocytes, which the thymus produces.
