Environmental scientists cite several challenges to protecting endangered species. Which of the following is NOT a difficulty faced by those working to protect an endangered species? Scientists who are focused on a single species may not recognize another species in peril. Extinction is natural in nature and its rate of occurrence has remained steady. Protection efforts may be slowed because of difficulty enforcing new regulations. Fundraising can be more difficult if the species is not perceived as valuable.

Answers

Answer 1

Answer:

Extinction is natural in nature and its rate of occurrence has remained steady.

Explanation:

As of right now we are going through what is known as the sixt extinction, and human acticity is one of the Main causes. (which has never happened before our time) Species are going extinct at a rapid rate, and considering how all life is connected it makes it easy to understand why the extinction rates can increase due to a biotic factor (niche) being "removed".

1. Discuss at least two attributes of a study that you would look for to determine whether or not it is rigorous.

Answers

Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.

Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.

Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:

- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".

- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.

- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

Once the neural plate edges have fused to become a neural tube, the tissues that were at the edges of the plate now form the __________ region the neural tube. Fill in the blank.

Answers

Answer: Dorsal.

Explanation:

The neural plate is a region of the dorsal ectoderm that develops into the neural ectoderm. It is a flat structure, with columnar appearing cells, and the formation of the neural ectoderm is the first step in the neurulation process. This region is generated from the thickened mid-dorsal surface opposite the primitive line of the ectoderm. From this epithelial zone the various types of neuronal and glia cells belonging to the nervous system are derived. For the neural plate to be built, it is necessary that the epiblast cells converge towards the midline of the embryonic disc forming a groove of the primitive line, delimiting a longitudinal axis of bilateral symmetry around which the embryonic structures and their organs will be aligned. From this moment on, the embryo will have a rostral (cephalic) and caudal (tail) region as well as a left and right side and a dorsal (back) and ventral (front) surface. From the folding of the neural plate or neurulation, the neural tube and the development of the entire nervous system will be formed.

The neural tube is tubular structure that undergoes modifications and will give rise to a central nervous system structure (encephalon and spinal cord).  The neurulation process begins by means of signals sent by the dorsal mesoderm and pharyngeal endoderm to the ectodermal cells located above these germ layers. These signals cause this area of the ectoderm to elongate into a columnar plate of cells. The elongation allows the differentiation of the cells of the future neural plate, with respect to the pre-epidermal cells surrounding the area.

So, the neural tube is formed by invagination from the dorsal region of the ectoderm (neural plate) induced by the notochord while it is forming. This occurs at the beginning of the third week of conception by a process called neurulation.

What are the mechanism that use to resist the antimicrobial agents?

There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.

These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.

There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

Mr. L was walking through the woods wearing shorts and sandals. He noticed a small tick on his ankle the same evening, and several weeks later he developed flu-like symptoms. A sample of his blood revealed the presence of long, wavelike cells that were twisting and waving. Based on the microscopic findings, which type of microorganism is responsible for Mr. L's symptoms

Answers

Answer:

Protozoa

Explanation:

The long, wavelike cells seen under the microscope would most likely be protozoa and the microorganism responsible for Mr. L's symptoms.

Tick as a vector is capable of causing diseases such as lyme disease, anaplasmosis, babesiosis, Powassan virus disease, tularemia, and a host of other diseases. Among all the diseases, babesiosis is particularly caused by a protozoan known as Babesia microti and it elicits malaria-like symptoms in individuals. Most of the other diseases are caused by bacteria pathogens while a few are caused by virus.

Apart from the above, the morphological characterization of the microorganism responsible for Mr. L's disease is typical for protozoans. Many of them are long and flagellated with a wave-like motion as a movement.

Hence, the case of Mr. L would be that of protozoa.

Cells dispose of large waste molecules through a process called

osmosis.
diffusion.
exocytosis.
endocytosis.

Answers

Cells dispose of large waste molecules through a process called exocytosis.

Exocytosis is the process through which cells can eliminate wastes, which might be useless or toxic, to the extracellular space.

-------------------------------

The endocytosis and exocytosis process refers to molecules transport mediated by vesicles.

Exocytosis occurs from and into the cell and needs energy to happen because it is active transport.Exocytosis involves vesicles or vacuoles. Vesicles or vacuoles can carry substances destined for exportation or cellular wastes. Wastes may be large molecules that result useless for the cells or that might be toxic. During the exocytosis process

         1) excretion compounds of varying nature accumulate within the  

             vesicle

         2) The vesicle migrates toward the cellular surface.

         3) Once in the surface, the vesicle's membrane fuses with the cellular

             membrane, and its content is expelled from the cell to the  

             extracellular space.

         4) Vesicle membrane remains fused to the cell membrane until it is

              reused during endocytosis events.

Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true

Answers

Answer:

the parasympathetic system keeps heart rate lower than the heart would beat on its own.  

Explanation:

The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.
