One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population
Answers
Answer:
The correct answer is - 0.20
Explanation:
According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.
It helps us to predict the genotype frequencies in a large population. If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1
p2+2pq+q2=1
The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.

First, there is a need to understand what the carrying capacity is as it relates to the environment:
Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has. The population of a species in an environment grows and oscillates around the carrying capacity of the environment.Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.
Answers
Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

Answers
Answer:
Between depths of tectonic plate boundaries and the outer core.
Explanation:
The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core. At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.

Defining Characteristics
The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed." The angiosperms are those plants whose seeds develop within a surrounding layer of plant tissue, called the carpel, with seeds attached around the margins. This arrangement is easily seen by slicing into a tomato, for example. Collectively, carpels together with the style and stigma are termed the ovary, and these plus associated structures develop into the mature

Answers
Answer:
Waxy Cuticle
Explanation:
Waxy Cuticle retains water. It's the closest in terms of surviving on land. For instance, the plants living in water do not need waxy Cuticle to retain or maintain water. The plants on land requires waxy Cuticle because the temperature is hotter than in the water and they are at higher risk of loosing water during hot seasons and climate. waxy Cuticle aids in their water retention allowing them to adapt to live on land.

Answers
Answer:
a tube-like body attached to a firm surface with tentacles on the opposite side of the attachment, surrounding the animal's mouth
Explanation:
A polyp is a type of body structure that a cnidarian can assume. The cnidarians, in turn, are invetebrate animals of aquatic life. This group of animals includes jellyfish, corals and sea anemones.
In polyp form, cnidarians are not actively moving, although some do move when they feel threatened. This is because they appear as a tubular structure, with one end fixed to the sea floor. The other end presents the animal's mouth, which is surrounded by tentacles that are responsible for capturing the prey needed for food.
