Given what we know about genetics, we can confirm that the case described in the question will be a result of a De Novo mutation.

A De Novo mutation is referred to as the most severe mutation type. This is a mutation that occurs even before embryonic development has commenced. They are usually the result of mutations in the DNA of the germ cells before being fertilized.

These mutations are responsible for a variety of disabilities and can target a wide array of genes to cause these effects.

I NEED HELP The measure of how resistant a solid is to shape change when a force is applied.
enyata [817]

<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>

A 154-lb adult man performs a moderate level of physical activity and regularly consumes 2700 Calories a day. State whether the
Arte-miy333 [17]

Answer:

The correct answer would be - remain the same.

Explanation:

In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:

weight                daily intake

132                        2250

154                        2450

176                        2650

198                        2850

220                       3050

242                       3250

In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.

Thus, the total calories he takes: 2700

burn by exercise: 295

should take: 2450

then = 2700 - (2450+295)

= 50 calories over the limit that will have negligible effect on the weight.

In comparing and contrasting different cultures, the gender roles:
saveliy_v [14]

Answer:

d. vary and change for both males and females from culture to culture

Explanation:

Gender roles vary for both females and males across cultures. This can be observed in the way some societies are patriarchal and some are matriarchal. For example: in many Asian cultures, traditionally males head the families. It's their responsibility to engage in outside work and take important decisions for the family while women take care of household chores. This is reversed in some cultures like that present in Meghalaya, India. Here women are dominant figures in households. They inherit property, give their family name to children and after marriage the man comes to live with the woman's family. Hence gender roles are variable culture to culture.
