Answer:
People may be at risk of developing anxiety or depression after experiencing a traumatic event or a natural disaster like a bushfire, flood, cyclone or earthquake.
Communities and individuals affected by a disaster can experience a range of thoughts, feelings and behaviours that can be intense, confusing and frightening. These are common reactions to an extraordinary situation. Fear, for example, is an important and normal reaction that helps activate our body and mind to make decisions to protect our own life and the lives of loved ones, friends and neighbours. It is also normal for the memory of intense fear to stay with us.
Following a traumatic event or disaster, many people deal with memories and ongoing feelings by drawing on their own strengths, as well as the support of others, and will gradually rebuild their lives and achieve a sense of wellbeing again.
However, it is common that some people struggle to deal with feelings and thoughts that may follow such an event. It's important to know the difference between a common reaction to a stressful or traumatic event and signs that indicate you should seek additional support.
The Churchill Crocodile was a British flame-throwing tank of late Second World War. It was a variant of the Tank, Infantry, Mk VI (A22) Churchill Mark VII, although the Churchill Mark IV was initially chosen to be the base vehicle.
The Crocodile was introduced as one of the specialised armoured vehicles developed under Major-General Percy Hobart, informally known as "Hobart's Funnies". It was produced from October 1943, in time for the Normandy invasion.
Answer:
Explained
Explanation:
Concordance: This is a term used in genetics. This term is used to imply the presence of the same trait/characteristic in both the members of a pair of twins.
Twins can be of 2 types. They are monozygotic twins and Dizygotic twins.Monozygotic twins are identical twins, i.e. they are formed from one zygote that later splits into two forming two embryos.
Dizygotic twins are non-identical twins or fraternal twins formed from the fertilization of two different eggs with two different sperm cells.
Concordance values can be calculated as:
C = Number of concordance pairs/(number of concordant pairs + number of discordant pairs)
Monozygotic twins generally have a concordance value of 44% for a specific trait.
Dizygotic twins have a concordance value of less than 5 % for a trait.
For identical twins the number of concordant pairs would be 50 out of 100.concordant pair would be
For non-identical twins, the number of concordant pair would be 17 out of 100.
For a recessive trait to be expressed, both the parents should be heterozygous for that trait.
Answer:
The answer is B. Infrastructure.
Explanation:
The infrastructure consists of the different fundamental facilities as well as systems that serve a country or city. They also include the services and facilities that are important to allow the economy to function properly. Infrastructure is usually composed of different public and private physical improvements. They include roads, railways, bridges, tunnels, water supply, as well as telecommunications.
It exists two ways through which infrastructure can be considered, hard or soft. Hard infrastructure is related to the physical networks that are relevant to allow the modern industry to function properly like roads, bridges, railways. The soft infrastructure consists of all the institutions that are related to aspects like the economy, health, and cultural standards of a country.
