In a population of 10,000 individuals, 400 express a recessive trait. How many heterozygotes are there expected to be?

We will use the Hardy-Weinberg equation ; p2 + 2pq + q2 = 1
q2 represent the frequency of the recessive trait in the population which is 400/10000 = 0.04. Then find frequency of the recessive allele.
q = 0.2. While we understand that p+q =1 ; p = 1-q ; p = 1-0.2 =0.8.
2pq represents the frequency of heterozygous trait in the population. Therefore 2*0.8*0.2 =0.32
0.32*10000 = 3200

A behavior with both innate and learned components that is irreversible and is triggered during a sensitive period.
rodikova [14]

Answer:

The correct answer is - Imprinting.

Explanation:

Imprinting is a behavior that includes both innate components and learning components and normally can not be irreversible. It is something that takes place at a specific sensitive period.

For instance, ducklings follow their mother is imprinting that is both innate and learned at a limited phase after birth during development. It can be visual or auditory or other ways that an animal can develop imprinting.

Please help me i don’t understand
Eddi Din [679]
1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.

2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.

3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches

4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

I tried my best hope this helps :)
