Answer:
False. Gases have no fixed shape or fixed volume but they can take up the space in a container.
The right option is D. vector-borne
Diseases carried from person to person through other hosts, such as animals or insects, are known as vector- borne diseases.
Vector-borne diseases are infectious diseases transmitted between humans or from animals to humans through the bite of infected hosts such as animals or insects. Most of these hosts are arthropod vectors which are bloodsucking insects such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Examples of vector-borne diseases include West Nile fever which is transmitted through the bite of an infected Culex mosquito, Leishmaniasis which is transmitted through the bite of an infected female sandfly and Tick-borne encephalitis (TBE) which is transmitted by ticks.
Answer:
The red blood cells will burst or rupture when it is diluted and it will be one transparent and visible.
Explanation:
This is because when red blood cells are in water or become too diluted,water will enter the red blood cells through the process of osmosis. Because water is an hypotonic solution, water from outside of the cell to the inside making the cells to continue to swell up and rupture ,a phenomenon known as haemylosis. When the red blood cells rupture, it loses haemoglobin and it's become transparent and visible.
Answer:
if its BB or Bb the offspring will show the dominant trait
Explanation:
If its bb then the trait wont be expressed
Answer: Fruit will not brown. Browning requires a functional enzyme.
Explanation:
Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>
Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.
If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.
