Answer:

community

Explanation:

Community refers to a group of populations of different species that live together in a defined habitat. These species exhibit interdependence for one or other resources. It is a level of the ecological organization just above the population and consists of hundreds of different types of organisms of various species.

Butterflies and flowering plants belong to different species. Butterflies are dependent on these plants for food. Therefore, these two together represent two populations of different species living together in habitat and are an ecological community.

Fruit flies have 8 chromosomes in their body cells, while dandelion cells have 16 chromosomes. Which species do you predict make

Finger [1]

Answer:

I think this might be the answer

Explanation: The answer is the same for every diploid species. It is half the number of chromosomes in somatic (body) cells. The number of cells in gametes (sex cells) is n and the number in somatic cells is 2n. For fruit flies gametes have 4 chromosomes, for mice, 20, for humans 23, for chimpanzees 24.

Hope this helps and stay safe.

Only 10% of American adults can name the capital of the Czech Republic. On a television game show the three randomly selected co

s344n2d4d5 [400]

Answer:

Problem 1: (a) 73%

Problem 2: (b) 78%

Explanation:

Problem 1:

The probability that a person can name the capital of Czech Republic is 10% which is 0.1. So,

p = 0.1

q = 1 - 0.1 = 0.9

n = 3

We will use the binomial distribution formula to find the probability that none of the contestants know the correct answer P(X=0). The binomial distribution formula is:

P (X=x) = ⁿCˣ pˣ qⁿ⁻ˣ

Where x = no. of successful trials

n = total no. of trials

p = probability of success

q = probability of failure

P(X=0) = ³C₀ (0.1)⁰ (0.9)³⁻⁰

P(X=0) = 0.729

0.729 x 100 = 72.9% ≅ 73% so option (a) is the correct answer.

Problem 2:

We will again use the binomial distribution formula to solve this problem. Here,

p = 70% = 0.7

q = 1 - 0.7 = 0.3

n = 20

We are required to find the probability P(12≤X≤16) which means we will compute P(X=12) , P(X=13), P(X=14), P(X=15) and P(X=16) using the binomial distribution formula and then add them to find the final answer. So,

P(12≤X≤16) = P(X=12) + P(X=13) + P(X=14) + P(X=15) + P(X=16)

= ²⁰C₁₂ (0.7)¹²(0.3)²⁰⁻¹² + ²⁰C₁₃ (0.7)¹³(0.3)²⁰⁻¹³ +²⁰C₁₄ (0.7)¹⁴(0.3)²⁰⁻¹⁴

+²⁰C₁₅ (0.7)¹⁵(0.3)²⁰⁻¹⁵ + ²⁰C₁₆ (0.7)¹⁶(0.3)²⁰⁻¹⁶

= 0.114 + 0.164 + 0.192 + 0.179 + 0.130

P(12≤X≤16) = 0.779

0.779 x 100 = 77.9% ≅ 78%

So, option (b) is the correct answer.
