Answer:
Explanation:
The use of ointment for bacterial treatment does not fall into the first line of defence.
The first line of defence are physical (skin,tears, mucus) and chemical barriers( white blood cells also called neutrophils) which are prepared to defend the body against infection. The skin which is one of the first line of defence is a barrier that prevents entry of microorganisms the body. When the first mechanism is not effective especially for pathogens then the second mechanism is activated to get rid of the microorganism.
The use of ointment does not belong to any barrier or defence mechanism this is because it is not a natural way of getting rid of microorganisms within the body system.

What data did the purification stage produce? How did this data help identify the transforming substance? (SAVAAS Chapter 11.1 Identifying the Substance of the Gene)
Answer: The purification gave evidence of the identity of the transforming material, meaning that the possible transforming substance was narrowed down.
Explanation: Removing lipids and carbohydrates suggest that these are not the transforming materials and removing protein suggests that this is also not a transforming material.
The swimming reflex is the combination of 2 unique factors. First, when submerged, babies will reflexively stop breathing through their nose. Secondly, their high voice boxes mean that any water will go into their _____.
Answer:
Trachea
Explanation:
The laryngeal reflex occurs and it is present in babies after birth. When water occupies or enters the mouth, the laryngeal reaction is triggered. While your infant is underwater, the glottis and epiglottis shut, keeping water from penetrating the throat(larynx and pharynx) and establishing a watertight barrier to the lungs. This is so to prevent the aspiration of water into the lungs.
Hemochromatosis is an inherited disease caused by recessive allele. If a woman and her husband, who are both carriers, have three children, what is the probability of all three children having a normal phenotype
Answer:
27⁄64
Explanation:
A recessive disease is expressed only when an individual carries two copies of the recessive allele (i.e., individuals must be recessive homo-zygous to suffer from the disease). In this case, both parents are carriers for hemochromatosis, i.e., both are heterozygotes carrying the defective allele, thereby the probability of having a child with a normal 'dominant' phenotype is 3/4, i.e., 3/4 individuals are expected to have an A_ genotype (1/2 AA + 1/4 Aa = 3/4), and 1/4 individuals are expected to have an aa genotype (where 'A' is the dominant allele and 'a' is the recessive allele associated with hemochromatosis). In consequence, the probability of having three children with the normal phenotype is 3/4 x 3/4 x 3/4 = 27/64.

Which option identifies the major method scientists use to share their research findings with other scientists?
(Select all that apply)
newspaper articles
peer-reviewed journals
conference presentations
Internet videos
The option that identifies the major method scientists use to share their research findings with other scientists is peer-reviewed journals. The correct option is B.
What is peer-reviewed journals?A scholarly publication is another term for a peer-reviewed publication. The peer-review process is used to ensure academic scientific quality by subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field.
Peer review is intended to assess the validity, quality, and, in some cases, originality of articles submitted for publication.
Its ultimate goal is to protect scientific integrity by filtering out invalid or poor articles.
Peer review research is not particularly well-developed, particularly as part of the broader issue of research integrity also it frequently produces contradictory, overlapping, or inconclusive results depending on scale and scope and it appears to suffer from biases similar to the rest of the scholarly literature.
Thus, the correct option is B.

Answer:
VII. Anaphase II
Explanation:
During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach Anaphase II, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole

¿A qué se refiere la sexualidad libre de coerción y violencia?
Para las mujeres y las niñas, el derecho a controlar su propio cuerpo y su sexualidad sin ningún tipo de discriminación, coerción o violencia es fundamental para su empoderamiento. Sin derechos sexuales, no pueden realizar sus derechos a la autodeterminación y la autonomía, ni pueden controlar otros aspectos de sus vidas. De hecho, son los intentos de controlar la sexualidad de las mujeres y las niñas los que dan como resultado muchos de los abusos de los derechos humanos que enfrentan a diario, incluida la violencia de género, el matrimonio forzado, la mutilación genital femenina y limitaciones en su movilidad, vestimenta y educación. , empleo y participación en la vida pública. Lo mismo ocurre con las lesbianas, los hombres gay, las personas bisexuales, las personas transgénero, las trabajadoras sexuales y otras personas que transgreden las normas sexuales y de género y que, como resultado, enfrentan un mayor riesgo de violencia, estigma y discriminación. Está claro: los derechos sexuales sustentan el disfrute de todos los demás derechos humanos y son un requisito previo para la igualdad y la justicia.
A nivel mundial, existe un gran debate sobre si definir los derechos sexuales y cómo hacerlo. IWHC cree que para superar algunas de las barreras políticas al reconocimiento, respeto, protección y cumplimiento de los derechos sexuales, necesitamos aclarar cuáles son.
IWHC, en colaboración con otras organizaciones líderes de derechos humanos y salud sexual, ha desarrollado la siguiente definición de trabajo de derechos sexuales:
Los derechos sexuales abarcan ciertos derechos humanos que ya están reconocidos en las leyes nacionales, documentos internacionales de derechos humanos y otros documentos de consenso. Se basan en el reconocimiento de que todas las personas tienen derecho, libres de coerción, violencia y discriminación de cualquier tipo, al más alto nivel posible de salud sexual; perseguir una vida sexual satisfactoria, segura y placentera; tener control y decidir libremente, y con el debido respeto a los derechos de los demás, sobre asuntos relacionados con su sexualidad, reproducción, orientación sexual, integridad corporal, elección de pareja e identidad de género; ya los servicios, educación e información, incluida la educación integral en sexualidad, necesarios para ello.

hope this helps you...atmosphere is a present around the surface of the earth but it is not present around the surface of the Moon why
Answer:
tmosphere is a present around the surface of the earth but it is not present around the surface of the Moon because
This reduces the amount of gravity on the moon. Strong gravity is needed to hold an atmosphere into place. With weak gravity, gases that are emitted from the surface quickly are lost to outer space. Another reason is because the moon does not currently experience plate tectonics and geologic upwelling. Plate tectonics allows for a recycling of crust and convergence and divergence of plates occurs and this leads to volcanoes and gases escaping at the boundaries. The moon is said to be geologically dead.

In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.
