Answer: Survival rate up to start of April = 76.67%

Explanation: size of colony = 150mice.

Size of colony in February =125mice.

Size of colony in march = 115 mice.

1. Survivorship rate in February

= Size of colony / size in February *100.

= 122 / 150 * 100

= 83.33% to the nearest hundredth

2. Survivorship rate in march

= Size of colony / size in march *100.

= 115/150 * 100

= 76.67% to the nearest hundredth.

The ultimate goal of sustainable development is to limit the future use of resources b. meet current and future resource needs C
egoroff_w [7]

The correct answer is B. Meet current and future resource needs.

Explanation:

Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.

irina [24]

Answer:

Frequency of p = 0.684

Frequency of p = 0.316

Number of individuals with homozygous dominant (AA) = 47

Number of individuals with heterozygous (Aa)= 43

Number of individuals with homozygous recessive (aa) = 10

Explanation:

Out of 100 people, 10 have albino skin (aa)

So, the frequency of homozygous recessive individuals (q^{2}) is \frac{10}{100} = 0.1

Now, q will be

= \sqrt{q^{2} } = \sqrt{0.1} \\= 0.316

As per Hardy Weinberg's equation -

p + q = 1

Substituting the value of q in above equation, we get -

p + 0.316 = 1p = 1 -0.316\\p = 0.684

Now the frequency of homozygous dominant (AA) will be

p^{2} = 0.684^{2} \\= 0.467

Hence, out of 100 people 0.467 * 100 = 46.7 or 47 people are homozygous dominant (AA)

Like wise out of 100 people 0.1 * 100 = 10 people are homozygous recessive (aa)

As per As per Hardy Weinberg's equation-

p^{2} + q^{2} + 2pq = 1\\

Substituting the values in above equation, we get -

0.467 + 0.316 + 2pq = 1\\2pq = 1 -( 0.467+ 0.1)\\2pq = 0.433

So, out of 100 people 0.433 * 100 = 43.3 or 43 people are heterozygous (Aa)
