It is more likely to be a SEDIMENTARY rock. Igneous rocks are made of lava so it is not very likely that a fossil is made of lava.

Describe the neural and renal mechanisms that control blood pressure.
Andrei [34K]

Answer:

The autonomic nervous system is the main neural regulator of circulation and blood pressure in the short term and beat by beat and exerts its function through various reflexes that regulate vasomotor tone, heart rate and cardiac output. At the renal level, the renin–angiotensin–aldosterone system is possibly the most important in the maintenance of arterial homeostasis.

Explanation:

Blood pressure is regulated by a series of interrelated autonomic systems and humoral reflexes, which continually adjust the determining elements of the system (heart rate, stroke volume, total peripheral resistance and circulating volume).The effective circulating volume is controlled by a series of reflex systems, which obtain information about the perfusion pressure (baroreceptors in the carotid bulb and aortic arch), plasma osmolarity (hypothalamus) and urinary sodium (distal tubule).The kidney has its own self-regulatory mechanisms. The reduction in renal blood flow is detected at the level of the mesangial cells of the juxtaglomerular apparatus, starting the renin-angiotensin system. The increase in angiotensin II produces on the one hand local vasoconstriction, and on the other hand stimulates the production of aldosterone by the adrenal cortex with the consequent tubular reabsorption of sodium and water.Antidiuretic hormone or vasopressin (released from the hypothalamus by stimulation of arterial baroreceptors and also by stimulation of angiotensin II) also acts at the renal level, which acts as a powerful and water-saving vasoconstrictor in the distal tubule.

Create a table in which you compare the components and functions of the following.
Sauron [17]

Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.

  • Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.

Basic elements:

  1. Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
  2. Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
  3. Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
  4. Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)

Monomer constituents:

  1. Nucleic acids: nucleotides
  2. Proteins: amino acids
  3. Carbohydrates: monosaccharides
  4. Lipids: fatty acids and glycerol

Functions:

  1. Nucleic acids: contains the hereditary information to synthesize proteins
  2. Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
  3. Carbohydrates: store energy (short term); form cellular structures
  4. Lipids: store energy (long term); the main component of biological membranes

Examples:

  1. Nucleic acids: DNA and RNA
  2. Proteins: lactase; collagen
  3. Carbohydrates: starch (polysaccharide); glucose (monosacharide)
  4. Lipids: phospholipids; cholesterol

Which statement describes a similarity between meiosis and mitosis
VLD [36.1K]

Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid. A diploid means containing the normal amount of chromosomes. This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes which are sperm and egg cells, the cells of sexual reproduction.

They are similar because crossing over happens in both.

1. How is a food chain different from a food pyramid?
Scilla [17]

Answer:

What are some differences between a food chain, web, or energy pyramid? Food chains show a limited feeding relationship between only a few organisms. Energy pyramid is the visual representation of the amount of energy, population, or biomass at each trophic level.
