The flu vaccine is a medicinal shot which is supposed to prevent/ and or decrease your chances of getting the flu. It is supposedly working as stated by the producers of this vaccine however many children have been given this vaccine and it dosen`t work. The recommendations are appropriate  as it is better to be safe than sorry. However there are some negative effects. For example a person would get a cold afterwards and this of course is sickness. Overall, I recommend not highly, but as i stated earlier it is better to be safe than sorry.

Answer: The flu can be caused due to an unpredictable virus that can cause mild illness in most of the people.

It is vulnerable to all the age groups including pregnant women, older people, and to the people having having some other medical conditions.

The people who are more prone to diseases like bronchitis or pneumonia should take vaccine to prevent themselves from these kind of flu.

The people who are above 65 years of age, or who are pregnant are eligible for the vaccine that is free and provided at the center of the NHS.

These vaccines are very helpful to the people prone to diseases.

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).

How did the work of Mary Leakey contribute to our knowledge of early hominids and an understanding of human evolution?
Alecsey [184]

Answer:

M.Leakey was a paleoanthropologist of  no formal  university education and British origin. Her major discoveries  were;

1. the proconsul skull

2. Zinjanthropus skull at Olduvai Gorge In Tanzania

3, system of classification of discovered stones.

4.Laetoli footprints at Laetoli sites.

However, her most outstanding  discoveries were proconsul skull (  projecting  face with no browridges, and presence of ape-like teeth shapes) and the Laetoli prints. She believed the skull belonged to ancestral Homo habilis, which  could be traced to origin of mankind.

The discovery of Laetoli  prints showed evidences of bipedalism and the origin  of Australopithecus. These prints and  the  skeletons she unearthed  proved that the ancestral of human race actually walked upright, nearly four feet tall in height.Hence she concluded that these prints actually belong to  the Australopithecus. This  brought a paradigm shift in modern understanding of human evolution of prehistoric times and the origin of  mankind,

Her discoveries generally  throw light on the <u>evolution of mankind </u>and  new understanding of <u>genesis of human race</u>
