Explanation:
Female sterilisation can be seen as an operation to permanently prevent pregnancy. sterilization for women is a procedure that blocks the fallopian tubes so that eggs do not reach the uterus. Many people call it getting your tubes tied. Doctors may call it tubal ligation or tubal occlusion. This is a permanent form of birth control.The fallopian tubes are blocked or sealed to prevent the eggs reaching the sperm and becoming fertilised.

What is the frequency of a wave that has a wavelength of .20 m and a speed of 22 m/s
Answer:
110 Hz
Explanation:
Find the frequency of the wave using the formula, frequency = speed / wavelength.
Plug in the speed and wavelength, and solve:
frequency = speed / wavelength
frequency = 22 / 0.2
frequency = 110
So, the frequency of the wave is 110 Hz

The largest population of a particular species that an ecosystem can support is the ecosystem's carrying capacity.
What is a carrying capacity?Carrying capacity in ecology refers to the number of individuals of a particular species that an environment can support.
Every ecosystem has a maximum number of biotic components that it can support to ensure the sustainability of its resources.
Therefore, the largest population of a particular species that an ecosystem can support is the ecosystem's carrying capacity.

Explain why the lack of surfactant would result in respiratory distress. Furthermore, what type of acid-base disorder might she develop and how would her body compensate. Be detailed in your explanation and support your answer with facts from your textbook, research, and articles from scholarly journals.
Answer:
Due to lack of expansion of lungs.
Explanation:
The lack of surfactant compound would result in respiratory distress because Surfactant enables the lungs to expand more easily which allows easiness in respiration. Without surfactant, the air sacs in the lungs will collapse very easily. This collapse leads to decreased amounts of air or oxygen in the lungs which makes it very difficult for the people or infant to breathe.
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.

Explanation:
In this experiment, you are looking at the effect of various germicides on microbial growth. The organism that you are using for this experiment is baking yeast, which is a eukaryote. Do you think that this organism would be more or less susceptible to the various germicides than a prokaryotic organism, such as bacteria?
Answer:
Less susceptible.
Explanation:
This organism would be less susceptible to the various germicides than a prokaryotic organism, such as bacteria because the form and structure of eukaryotic organism is different from the prokaryotic organism so the germicides no or less affected the eukaryotic organism so we can say that the the eukaryotic organism which is used in baking would be less susceptible to the various germicides than a prokaryotic organism.

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 process1) 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.

What is the role of pitutary gland in puberity
Answer:
Puberty has begun. The trigger for puberty in both boys and girls is the production of 'gonadotrophin releasing hormone' (GnRH) from a part of the brain called the hypothalamus. This hormone stimulates the pituitary gland to release two hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

What is the best way to ensure that results of a study are generalizable to a population?
By making sure to use as many participants as possible
By making sure the results are significant
By making sure to use an equal number of men and women
By using random assignment
By using a random selection of people in that population
The best way to ensure that results of a study are generalizable to a population is by using a random selection of people in that population
The goal of every research experiment is to obtain results that are generalizable to a whole population.
This is achieved by the method of random selection. In random selection, members of the of the population are selected in such a way that is representative of the entire population. If for instance, I want to study a school having six classes which comprises of boys and girls. There are 700 students in the school and I need only 180 students to participate in a study whose results will be extrapolated to all the 700 students. I can decide to randomly select 15 boys and 15 girls from each class to participate in the study. This is an example of random selection.
In this way, the results obtained from the study is reflective of the whole population even though only a sample of the population actually participated in the study.

In a study involving a cell-free translation system from coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of a new class of translation-targeting antibiotics that bind to the large ribosomal subunit, the ribosomal complex forms, the initiator tRNA binds the mRNA, the second tRNA enters the A site of the ribosome, but no peptide bonds form. Which of the following is a likely function of these new antibiotics?
a. Blocks peptidyl transferase activity
b. Inhibits tRNA aminoacyl synthetase function
c. Inhibits ribosomal translocation along the mRNA
d. Prevents anticodon base-pairing with the codon
e. Blocks binding of the Shine-Dalgarno box to the rRNA
Answer:
c. Inhibits ribosomal translocation along the mRNA.
Explanation:
Initiator tRNA is thought to bind directly to P-site of small ribosomal sub unit. These tRNA are positioned at P site and remain attached to tRNA located at this site. Initiation factor helps to mediate this event.

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.
