Answer:
Unless the egg is fertilized by a sperm while in the fallopian tube, the egg leaves the body about 2 weeks later through the uterus — this is menstruation. Blood and tissues from the inner lining of the uterus combine to form the menstrual flow, which in most girls lasts from 3 to 5 days.

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
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.

why does a rational producer reject the business in increasing stage
Answer:
In three stages of production to which are hold by the law of diminishing marginal returns the second stage is considered to as the rational stage of production as compared to the first and third stage this is due to the fact that this stage it comes out with the best assumptions for efficient and sustainable production, thereby the stage it simultaneously shows the positivity of the average products and marginal product hence, in the increase of labour the total production or outputs increased likewise with the same quantity of fixed factor, therefore this stage it gives direction to the producer on how the higher units of output can be produced.
Unlike the first stage to which it shows each additional variable could enhance more production and such this it signifies an increasing of marginal return but for this case it do not give out the direction in permanent production since labours are needed fewer and in the decrease in number of labour can brings about underproduction.
Also the third stage marginal return is frankly negative because in adding more variable inputs will further led into adding more number of labour hence the increase of labour will contributes to under production as it may be due to labour capacity and efficiency concern.
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
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.

Which of the following is NOT a function of behavior?
A. To produce ATP.
B. To find food.
C. To reproduce.
D. To avoid predators.
Answer:
A to produce ATP as you are subconsciously producing ATP and you can not control it
Explanation:
To find food, to reproduce, and to avoid predators all are the functions of behavior except the production of ATP. Thus, the correct option is A.
What are the functions of behavior?Behavior is the range of actions and manners which are made by individuals, systems or artificial entities in a given environment. This can include other systems or organisms as well as inanimate physical environment.
The four main functions of behavior of an organism are attention, escape, access, and sensory needs. These four functions allow us to understand and categorize someone's actions, as well as determine the behavior of organisms such as finding food, reproduction, and avoiding the predators.
Therefore, the correct option is A.

Lane 2 Radiolabeled lacO DNA + Lac Repressor protein preincubated with lactose
Lane 3 Radiolabeled lacO DNA + Lac Repressor protein missing its DNA binding domain
Lane 4 Radiolabeled lacO DNA + Lac super-repressor (Is) preincubated with allolactose
Lane 5 Radiolabeled lacO DNA + lac repressor protein

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.

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