Which of the following is characteristic of the parasympathetic division? A. stimulates secretory activity B. dilated airways C. increased heart rate D. inhibited digestion and elimination

Answers

Answer 1

Answer:

The correct answer is: A. stimulates secretory activity

Parasympathetic nervous system is a part of the autonomic nervous system (a division of the peripheral nervous system (PNS), so it means it regulates unconscious actions in an organism. Parasympathetic system is known as a system for stimulation of "rest-and-digest", when the body is at rest (differ than sympathetic which is active for fight-or-flight response). Parasympathetic system works usually after the meal and it is involved in the functions such as, secretory activities (salivation, lacrimation ), urination, digestion and defecation..

How does anatomy provide evidence for evolution?

Answers

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures. These are structures that unrelated organisms share because they evolved to do the same job.

Which of the following is NOT a valid scientific method used by modern scientists to date fossils?A Use of index fossils
B Relative position of fossils in rock strata
C Analysis of nitrogen-14 isotopes
D Analysis of Uranium-238 isotopes

Answers

A Use of index fossils

Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them. Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.

A plant's cell wall is made of cellulose fibers. What is the purpose of a plant's cell wall?

Answers

It allows the plant to stand upright.

The purpose of a cell wall within a plant cell is to provide the cells with protection and structure. It allows also allows the plant to grow tall and strong, cell walls act like a shield and a spine for a plant.

solar radiation travels through the earth's atmosphere and warms the planet's surface. greenhouse gases like carbon dioxide in the earth's atmosphere reabsorb the heat and warm the planet. the amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. this gradual temperature change is thought to have many negative environmental consequences. which of these might be a positive effect of the increase in carbon dioxide levels? a) rise in sea levels b) decrease in plant growth c) increase in plant growth d) increased melting of ice caps

Answers

c) increase in plant growth, because plants need carbon dioxide to survive

Glands in your neck contain digestive enzymes that help digest starch. Cells that produce and package digestive enzymes must contain relatively large amounts of __________ and ____________ in comparison to other cells.. . A). lysosomes; ribosomes. . B). ribosomes; Golgi bodies. . C). mitochondria; ribosomes. . D). Golgi bodies; mitochondria

Answers

The right answer is B). ribosomes; Golgi bodies.

Their function is the synthesis of proteins. Each ribosome consists of 2 subunits. In ribosomes there are two populations by their location, the free ribosome and those that are bound to a membrane system to form rough endoplasmic reticulum. Free ribosomes produce soluble proteins whose activity will take place in the cytosol and the nucleus. The rough endoplasmic reticulum membrane-bound ribosomes synthesize proteins that must leave the cell, such as hormones, but also synthesize proteins for membranes.

The Golgi apparatus: consists of vesicles from the rough endoplasmic reticulum, but without ribosomes (diameter 50 nm). There will be fusion of the vesicles with the dictyosomes or saccules of the Golgi of Cis side Then will advance contents, in particular the proteins on the side Cis towards the side Trans. And finally we will have budding vesicles, some surrounded by a protein structure (clathrin vesicles) on the side Trans.

If the cell must digest and package enzymes for transport, the glands will have more ribosomes and golgi bodies than other types of cells. The answer is B. Mitochondria does not produce or package digestive enzymes, and lysosomes only digest material that is engulfed into the cell.

1. How does the number of vascular bundles in the root compare to the number of vascular bundles in the stem? 4. In which region of the root would you expect to find the specialized cells of vascular tissue? 5. In which region of the root are the cells genetically identical? Explain why.

Answers

In terms of vascular plants, they help maintain the water cycle. The property of these plants enables them to carry out this function is their well-developed vascular system. These type of plants are more evolved and developed than nonvascular plants because of its specialized characteristics like xylem, which is a tissue that is responsible for its framework and not only that, it is also has a greater mechanism for water transference.
