Explain the term "Poly Inheritance" and give an example of a human trait that is controlled in such manner
Answer:
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Some examples include height, skin color, eye color and weight.
- In polygenic inheritance the "dominant" capital genes are additive, each capital gene adding one unit of color to the genotype.With more capital genes, the phenotype (appearance) gets darker.

You are interested in analyzing the segregation of petal color in tulips over generations. You are tracking red and white petal colors, and lets assume that petal color results from a single-gene. You know from a trial cross that the F1 progeny from crossing a pure red tulip to a pure white tulip results in all red progeny. For the following questions, use the letters R and r to denote petal color genotype and make sure to clearly indicate the associated phenotypes.
Petal Color Questions
1. Based on the information given above, what do you know about which trait is dominant and which is recessive? Why?
a. If "R" is used to denote the genotype of the dominant allele, which petal color does "R" represent?
b. If "r" is used to denote the genotype of the recessive allele, which petal color does "r" represent?
Answer:
1. R is dominant, and r is recessive. I know this information because the crossing of two pure red and white tulips means that the red tulip genotype is RR, and the white is rr. In other words, they are two h0m0zygous alleles. When we do a Punnet square, we can see that all the progeny is red since it is the trait that dominated over the white one.
a. R represents the red petal color.
b. r represents the white petal color.
Explanation:
To determine which gene is the dominant and which one is the recessive, we have to look at the information that we have.
We know that the cross of a pure red tulip and a pure white tulip results in all red tulips. If we know that they are pure, they are hom0zygonious (RR and rr).
When we draw a Punnet square we can see that the offsprings will all have the genotype Rr and as we knew that offsprings were all red, we can deduce that the domiant trait is red (R), while the recessive one (white) is r. In other words, the dominat gene (red) will express itself while the recessive(white) won't. As a result, the tulips will be red.

Answer:
This question is incomplete and unclear as the question is not clearly expressed. However, the terms in the option will be explained for better understanding. Please find the explanation below.
Explanation:
Global warming is a phenomenon whereby the temperature of the Earth's surface undergoes a gradual increase. Global warming is caused by the actions of certain gases that possess the ability to trap and emit heat called GREENHOUSE GASES e.g carbon dioxide, methane etc.
The combined effect of greenhouse gases that leads to global warming is referred to as GREENHOUSE EFFECT. Some of the effects of global warming are as follows: melting of polar ice caps, rising sea levels, drought, and an increase in the frequency and severity of storms.

In many large mammal populations, highways can be barriers to movement - individuals rarely cross them. One solution to this problem has been to install overhead bridges for wildlife to safely cross. The goal is to increase gene flow between the populations on either side of the highway. Which of the following would you expect to see if the bridge is successful in its goal?
a) The two populations would have different mutation rates
b) We would see fewer heterozygotes in both populations
c) Higher levels of drift would occur after the bridge is installed
d) The two populations would become more genetically similar
e) Both populations would decrease in size
Answer: c. Higher levels of drift would occur after the bridge is installed
Explanation:
Based on the information given in the question, if the bridge is successful in its goal and overhead bridges are installed for wildlife to safely cross, then there'll be higher levels of drift after the bridge is installed.
Since the highways are barriers to the movement of the wildlife, overheard bridges will bring about movement on the other side of the highway and this will result in and increase in drift between both parts of the highway. This will also help in the increase of gene flow between the populations.
Therefore, the correct option is C.

Rinderpest (a virus) has high mortality in wildebeest (a kind of herbivore), especially in young animals. From the early 1960s, after the elimination of a virus called rinderpest, the wildebeest population has increased dramatically from 1958 to 1978. The elimination of rinderpest impacted the wildebeest population. What type of factor is rinderpest
Answer:
density-dependent, top-down factor
Explanation:
In biology, limiting factors are resources and other conditions in the environment whose presence/availability limit the population growth rate. Density-dependent factors refer to the conditions whose effects on the size/growth of the population vary depending on the population density. Some examples of density-dependent factors include diseases, competition, and predation, etc. These factors can exhibit a positive or negative correlation with the population size. Moreover, bottom-up population control (species limitation by resources) refers to limitations placed by resources allowing growth (e.g., food source or habitat), while top-down population control (limitation by enemies), refers to limitations placed by factors that control the death rate in the population (e.g., predation or diseases).

secondary succession
Explanation:
Large, low intensity disturbances, such as plowing in conventional agriculture, result in moderate amounts of succession, where species can survive in the soil and quickly recolonize areas after a disturbance. This type of succession is often called secondary succession
what is the diffention of Oceanic - Oceanic Boundary
At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or subducted, under the other (Figure 4.6. 1). Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate.Sep 17, 2019
The oceanic plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone. If the magma is too viscous to rise to the surface it will become stuck in the crust to create intrusive igneous rocks
8. Which of the following can be used to determine the composition of a star?
O A. Light from sunspots
O B. Line spectra
O C. The star's magnetic field
D. Blackbody spectrum
Answer:
Line Spectra
Explanation:
Stars are astronomical or celestial objects that have self-luminosity and are present in the universe. The composition of a star can be determined by the line spectra. Thus, option B is correct.
What are line spectra?The line spectrum has been constituted of the emission of the radiations with wavelengths that makes the isolated lines due to the excited atoms emitting various colors.
The spectroscope detects the Fraunhofer lines with various wavelengths and colors. The various constituent particle of the star will produce different colored lines.
The strength, intensity, and color of the spectral line can be used to determine the various components of the star. The emitted lights are compared to periodic characteristics.
Therefore, option B. the line spectrum can determine the composition of a star.

The statement that best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring is "random alignment increases the number of possible chromosome combinations in the gametes"
MEIOSIS:
Meiosis is the process by which a single cell produces four daughter cells that are genetically different from one another. In the meiotic process, pairs of homologous chromosomes align randomly along the metaphase plate in a stage called METAPHASE. The random alignment is a unique process of meiosis because it helps generate genetic variation in the offspring of sexual reproduction.This random alignment increases the number of possible chromosome combinations in the gametes.https://brainly.com/question/3712307?referrer=searchResultsL

A strain of a cereal grain can be either dark tan, medium-dark tan, medium tan, light tan, or cream colored. When a dark tan and a cream plant are crossed, all F1 are medium tan. The F2 are distributed in a ratio of 1:4:6:4:1 from darkest to lightest. How many genes are involved in this coloration?
Answer:
The correct answer is - 2 genes.
Explanation:
The number of genes involved in the coloration of the strain of cereal grain, could be either dark tan, medium-dark tan, medium tan, light tan, or cream-colored if all F1 are medium tan when crossed a dark tan crossed with cream-colored, can be calculated as follow:
suppose there are only two gene - TT dominant over tt and CC dominant over cc
then the cross would be - RRCC - rrcc
gametes - RC and rc
Cross F1: RrCc
Self cross in F2:
offspring by Punnet cross are:
RRCC -->1/16
RRCc, RrCC .---> 4/16
RrCc, RRcc, rrCC--->6/16
rrCc, Rrcc--->4/16
rrcc ----> 1/16
thus, the correct answer is 2 genes
Herd behavior benefits wildebeests by (1 point)
O increasing the number of resources availablė.
O allowing altruistic behavior.
O decreasing the chance of spreading disease.
O helping individuals find mates.
Answer:
helping individuals find mates.
Explanation:
took test
The correct answer is option d helping individuals find mates.
We can begin the solution for this one with a method of elimination.
2 cannot be proper due to the fact herding conduct nearly definitely will increase the possibility of spreading diseases. For 3, having extra people in a set affects more opposition and consequently fewer assets so we are able to get rid of that one as well.Then the selection is among 1 & four. You ought to make a controversy for four however it appears a piece indistinct concerning the precise advantages of altruistic conduct. I'd argue that altruistic conduct is extra of an effect than a motive of sociality/herding.Choice 1 is a not unusual place reason for sociality in animals. In species that do not stay in social organizations trying to find buddies may be very high priced in phrases of time and electricity and publicity to predators. It's a whole lot less difficult to discover a mate while many people are residing in proximity. Because replica is this kind of essential a part of the existence cycle I consider 1 is the exceptional answer.What is herd behavior?Herd conduct is the conduct of people in a set appearing together without centralized direction. Herd conduct happens in animals in herds, packs, chook flocks, fish faculties, and so on, in addition to in humans.
Thus it is clear that the option that helps individuals find mates is the correct answer.

Which of the following variables did Pasteur change in his experiment to test the hypothesis of
spontaneous generation?
The variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask
Pasteur in 1856 was known for his contribution to the science world through the study of the causes of spoilage in beer and wine. He demonstrated his knowledge from his discovery of the properties of fermentation by microorganisms.
He demonstrated and discovered that airborne microbes were the cause of food spoilage not a spontaneous generation with his swan-neck flask experiment. He went ahead with a suggestion that if microbes were responsible for food spoilage and fermentation, they could also be responsible for causing infection and this was the foundation for the germ theory of diseases.
In the later year, Pasteur established his previous experiment with a new one. In this new experiment, he made several flasks with long, twisted necks called the swan-neck flasks where he boiled broth and sterilized it. The essence of the swan neck design is to inhibit the introduction of airborne microorganisms into the flask by trapping them between the twists and bends of the flask and also to allow the exchange of air in the flask with the surrounding air.
Based on the theory above, we can conclude that the variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask
