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.

The cell membrane consists of ONE layer of phospholipids.
A. True
B. False
Answer: Hi there I think That I can help You!!!
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

Brian indicates that the mutation is in a gene found in the mitochondrial DNA. What does Brian mean by that and why did he signify mitochondrial DNA
Answer:
Change occur in the genetic makeup.
Explanation:
Brian means that the change occur in the genetic makeup of the mitochondrial DNA that change the structure as well as the function ability of mitochondria which is responsible for the generation of energy for the cell. The mitochondrial DNA are passed from mother to offspring through the egg cell. He signify mitochondrial DNA because the change occur only in the mitochondrial DNA not in the whole organism's DNA.
Brian indicates that the mutation is in a gene found in mitochondrial DNA. What Brian means by this is that mitochondria contain a single circular chromosome that encodes 13 proteins, and that may be due to abnormalities of mitochondrial DNA, to understand better we need.......
Abnormalities in mitochondrial DNAEach cell has several hundred mitochondria in its cytoplasm. Mitochondria contain a single circular chromosome that encodes 13 proteins, several ribonucleic acids (RNA, ribonucleic acid) and several regulatory enzymes. However, > 90% of mitochondrial proteins are encoded by nuclear genes. For practical purposes, it is assumed that all mitochondria are inherited from the cytoplasm of the egg, so mitochondrial DNA comes only from the mother.
Mitochondrial diseases can result from abnormalities of mitochondrial DNA or nuclear DNA (eg, deletions, duplications, mutations). Tissues with high energy production (eg, muscle, heart, and brain) are at particular risk of dysfunction due to mitochondrial abnormalities. Specific abnormalities in mitochondrial DNA result in characteristic manifestations. Mitochondrial diseases are equally common in men and women.
With this information, we can say that mitochondria have DNA and can undergo mutations, which can cause abnormalities in this DNA.

A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers
Answer:
B) Trees at high elevations
Explanation:
The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.
The tree leaves, which are the main key to the tree's photosynthesis, absorb the oxygen and Co2 from the air, which are converted into nutrients. Without proper nutrients, the trees may die out.

Which type of reproduction provides organisms with the following advantages? Desirable traits can be selectively bred for in a population of organisms. More genetic diversity that might benefit individuals when environment changes.
A. Asexual reproduction
B. Sexual reproduction
Answer:
Sexual Reproduction
Explanation:
Since sexual reproduction automatically causes genetic diversity(crossing over, DNA from both parents, etc.) it produces desirable traits for organisms. Asexual reproduction does not bring in new and desirable traits and is more of a copy of the parent.

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.
para realizar un Proyecto debemos primero buscar la necesidad. ¿Por qué?
Answer:
necesitamos conocer cuales son los motivos que impulsan la fabricación/obtención del producto y/o servicio
Explanation:
Un proyecto se considera un esfuerzo temporario asociado a un conjunto de actividades las cuales son planificadas de antemano a fin de producir un determinado producto y/o servicio. Por ejemplo, en el área de biología molecular y biotecnología, un proyecto podría consistir en la planificación de las actividades necesarias para sintetizar una hormona en particular (insulina) utilizando plantas como biorreactores. Las etapas o fases por las cuales debe transitar cualquier proyecto de índole tecnológico son: 1-planteamiento de un problema: cual es la necesidad que impulsa el desarrollo del bien y/o servicio; 2-búsqueda de información relacionada al proyecto: en el ejemplo citado, cual es la especie de planta más factible de ser utilizada como biorreactor para producir insulina, cuales son los materiales requeridos para llevar a cabo este proceso, etc; 3-diseño y planificación del proyecto: cuales son los plazos estipulados para la puesta a punto del proyecto, cómo obtener los recursos necesario para llevar a cabo estas actividades, evaluación de los riesgos a los que se enfrenta el producto/servicio, etc; 4-construcción del proyecto: consiste en llevar a cabo las actividades delimitadas en el paso anterior, y 5-evaluación y divulgación: consiste en la obtención final del producto y/o servicio, como así también de las medidas de publicidad (divulgación) que tienen como objetivo crear un nicho de mercado para el producto/servicio.

Both microscopy and motility agar are used to confirm microbial mobility. Research techniques involving microscopic determination of mobility and explain why both microscopy and motility agar are required to determine motility in some microbes.
Answer:
One allows microbe to move in the medium and the other allows to see it.
Explanation:
Both microscopy and motility agar are required to determine motility in some microbes because both substances helps to find out the mobility in the microbes. Motility agar is the medium that allows microbes to swim if they have flagella in their body while on the other hand, microscope is used to see the movement of microbes in motility agar. Microbes are small creature which can't be seen through naked eyes so we used microscope for it.
