Which is an autonomic body function? squinting in the sunlight salivating at the thought of a hamburger raising your hand in class bending over to pick up a book you dropped
Answer:
salivating at the thought of a hamburger
Explanation:
The autonomic functions of the human body are governed by the autonomic nervous system, which is an involuntary system that transmits nerve impulses from the central nervous system to the periphery, stimulating peripheral organs and systems.
Salivating at the idea of a hamburger is an unconscious action, that is, we cannot control it; such as the heartbeat, breathing, among other actions of our human body.

1. A group of students analyzed four biological samples that each contain a different macromolecule.
Here the data is given in the table, based on that we can say that sample 3 is most likely to contain RNA.
Each macromolecule has a different structure and composition other than C, H and O being common.RNA and DNA both are nucleic acid - a macromolecule that is composed of a pentose sugar, phosphate group and nitrogen base(purine and pyrimidines).That can be seen in table number 3- C, H, O, N, sugar, phosphate chain.2.The transmission of genetic material from one generation to next is necessary for the survival of species.
one property that ensures a reliable transmission of genetic information is complementary base pairing.That is a pyrimidine base will only pair with the correct purine base and the then only the DNA replication occurs efficiently.This leads to transmission of genetic information.To learn more about macromolecules :

B. Select questions those are not complex.
C. Ask questions rapidly.
D. Touch patients within the cultural boundaries of their

What is the primary function of the phloem in vascular plants?
Answer:
Phloem is the food transporting vesicles of a vascular plant
Explanation:
Phloem and Xylem together forms the vascular tissue. While Xylem transport fluid in the plant , phloem is responsible for transportation of soluble organic substances such as sugar, protein etc. Phloem transports food produced during the process of photosynthesis in leaves to all other non-photosynthesizing body parts such as stem and roots. The food travels from the leaves to the roots with the assistance of gravity.
The substance in phloem travel through the “sieve tube members” and “ companion cells” .

Consuming more than 60 grams of fiber per day poses some health risks, such as ________. decreased mineral absorption due to chemical binding by the fiber blockage of the intestinal tract decreased appetite in some individuals all of these choices are accurate.
Final answer:
Health risks associated with consuming more than 60 grams of fiber per day include decreased mineral absorption, blockage of the intestinal tract, and decreased appetite. All of these options are correct, highlighting the need for balanced fiber intake.
Explanation:
Consuming more than 60 grams of fiber per day poses some health risks, such as decreased mineral absorption due to chemical binding by the fiber, blockage of the intestinal tract, and decreased appetite in some individuals. Indeed, all of these choices are accurate. While dietary fiber is beneficial and necessary for proper digestive health, excessive intake can lead to these adverse effects. High levels of fiber can interfere with the absorption of minerals like calcium, iron, and zinc because it binds to these minerals, making them less available to the body. A very high-fiber diet can also lead to intestinal blockages, especially if fluid intake is not increased concurrently. Moreover, fiber is known for its satiating effect, which can be advantageous for weight control but might lead to a decreased appetite and potential undernutrition if intake is excessively high.

Four laws or principles are involved with the study of stratigraphy. They are _____.
Four laws or principles are involved in the study of stratigraphy are:
1. Principle of original horizontality
2. Law of superposition
3. Law of crosscutting relationships
4. Principle of Lateral Continuity
Answer:
law of original horizontality, law of superposition, law of original lateral continuity and law of cross-cutting relationships.
Explanation:
Before we know the principles of Stratigraphy, we need to understand what it is. To do this, let's first look at the origin of the word statigraphy: from Latin stratum means layer and from Greek graphia means field of study. From this we can understand that stratigraphy is the study of layers. Therefore, we define stratigraphy as the study of the sedimentary rock layers and it seeks to determine the processes and events that formed them.
Now that we know what Stratigraphy is, let's know its principles:
Law of superposition: In any succession of strata of rock (which has not been deformed), the oldest stratum is positioned lower, with the successively younger strata being positioned higher. This principle allows us to identify the order of formation of the strata, which is the basis of all historical interpretation of stratigraphic rocks. law of original horizontality: Sedimentary deposits usually accumulate in horizontal layers under the influence of gravity. law of original lateral continuity: Sedimentary layers are continuous, extending to the margins of the deposition basin, or tapering laterallylaw of cross-cutting relationships: states that an intrusive or faulty rock that cuts a sequence of rocks is younger than the rocks it cuts.The constant balancing of an organism's energy-producing and its energy-using processes is called

Two major differences in the morphology of spermatids and spermatozoa
The correct answer is that spermatids are larger and have a round shape, while spermatozoa are smaller and have a flagellum.
To understand the differences between spermatids and spermatozoa, one must consider their stages in spermatogenesis, the process by which sperm are produced.
Spermatids are the haploid cells that result from the second meiotic division of secondary spermatocytes. They are characterized by the following morphological features:
1. Size: Spermatids are larger than spermatozoa. This is because they have not yet undergone the final stages of differentiation and maturation that will transform them into mature sperm cells.
2. Shape: Spermatids have a round shape. They do not possess the elongated form that is typical of mature spermatozoa.
3. Nucleus: The nucleus of a spermatid is larger and less condensed compared to that of a spermatozoon. The DNA within the nucleus of a spermatid is not yet fully packaged with protamines, which are proteins that replace histones during spermiogenesis, leading to a more compact nucleus in the spermatozoon.
4. Cytoplasm: Spermatids have a significant amount of cytoplasm, which contains organelles and other cellular components necessary for their development into spermatozoa.
Spermatozoa, on the other hand, are the mature, motile sperm cells. They exhibit the following morphological characteristics:
1. Size: Spermatozoa are smaller than spermatids due to the loss of excess cytoplasm and the condensation of their nucleus.
2. Shape: Spermatozoa have an elongated shape with a distinctive head, midpiece, and tail. The head contains the condensed nucleus, the midpiece has mitochondria arranged in a helical fashion to provide energy for movement, and the tail is a flagellum that propels the sperm.
3. Flagellum: One of the most notable features of spermatozoa is the presence of a flagellum, which is an elongated structure that enables them to swim. Spermatids do not have a flagellum.
4. Acrosome: Spermatozoa have a specialized structure called the acrosome at the tip of their head. The acrosome contains enzymes that help the sperm penetrate the egg during fertilization. Spermatids begin to develop an acrosome, but it is not fully formed until the spermatozoon stage.
In summary, the two major differences in the morphology of spermatids and spermatozoa are that spermatids are larger and have a round shape, while spermatozoa are smaller, have an elongated shape with a distinct head, midpiece, and tail, and possess a flagellum for motility. These differences are crucial for the function of spermatozoa in fertilization.
