What effect might high temperature or irregular pH levels have on facilitated diffusion?

A small island is home to a unique population of land snails. This population was founded by 10 individuals that floated to the

vekshin1

Answer:

The Island population likely has fewer alleles-that is versions of genes-than the mainland population.

A- Agree B- Disagree

Genetic drift is more pronounced in the island population than in the mainland population in these first few generations

A- Agree B- Disagree

Some harmful traits may have become more common in the island population than in the mainland population

A- Agree- B- Disagree

Biologist observed genetic drift but not evolution

A- Agree B- Disagree

Explanation:

If there was genetic drift, then allele frequency either increased or decreased by chance, irrespective of natural selection that is irrespective to weather those alleles helped individuals survive in the island environment. In molecular genetic data, there are statistical signature in the population variation that indicate weather selection or other processes occurred.

Question 1

Nadya [2.5K]

Answer: Question 1 answer: Skin cells continually replicate

Explanation: The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.

Question 2 answer: Heart cells undergo terminal differentiation

Explanation: Different cell types (e.g., neurons, skeletal and heart myocytes, adipocytes, keratinocytes) undergo terminal differentiation, in which acquisition of specialized functions entails definitive withdrawal from the cell cycle.

Question 3 answer: DNA replicates in the nucleus

Explanation: DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.

Question 4 answer: The ability to reverse terminal differentiation might affect gene expression in a complex organism

Question 5 answer Cytoplasm replicates during mitosis

Explanation: This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. ... The outcome of binary fission is two new cells that are identical to the original cell.
