Suppose your friend investigated the color of pea pods and concluded that green pods (G) were dominant over yellow pods (g). What experimental evidence would be needed to support this conclusion?
Answers
This information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines.
The observed phenotypic frequency is the number of individuals that have a specific observable trait (in this case, green pods or yellow pods).A dominant trait produces a 3:1 phenotypic rate in the second generation (F2) of a genetic cross between two pure lines.In conclusion, this information can be confirmed by obtaining the observed phenotypic frequency in the second generation (F2) of a genetic cross between pure lines..

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

What are stem cells? How are embryonic stem cells different from adult stem cells?
Answers
Answer:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated.
Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent, meaning that they can differentiate into any cell type. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

A lone wolf travels hundreds of miles from his original pack and joins a new pack in a different range, affecting the gene pool through which mechanism?
A. genetic drift
B. recombination of alleles
C. gene flow
D. no effect
Answers
Answer:
a. genetic drift
A lone wolf travels hundreds of miles from his original pack and joins a new pack in a different range, affecting the gene pool through genetic drift. The correct option is A.
What is genetic drift?
Genetic variety and genetic drift are two of the factors of evolution that are both random processes. Allelic drift, also known as genetic drift, is the change in allele frequency that is most frequently observed in small populations.
Due to random sampling, some alleles in a small population may be lost because of the low allele frequency in a small population. As a result, the population's genetic diversity declines.
Gene flow is the transfer of genes or alleles from a population that resides in one location to a population that resides in another. The movement of various alleles into a new population, it raises genetic variation.
Therefore, the correct option is A. genetic drift.

How have plants evolved?
Give at least 5 examples.
Answers
Answer:
Over time, plants had to evolve from living in water to living on land. In early plants, a waxy layer called a cuticle evolved to help seal water in the plant and prevent water loss. ... To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved (Figure below)
Explanation:
1 DNA evidence suggests that the first eukaryotes (green plants) evolved from prokaryotes (through endosymbiotic events) between 2500 and 1000 million years ago. ... Cyanobacteria have a close evolutionary relationship with eukaryotes. They have the same photosynthetic pigments as the chloroplasts of algae and land plants.
2Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. ... All land plants evolved from an aquatic ancestor, and it was after colonisation of the land that the gibberellin mechanism evolved.
3 700 million years ago
The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago — much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.
4 The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago).
5 Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
