What is the genetic make-up of an organism?
Answers
Answer:
Explanation:
In a broad sense,genetic makeup of an organism can be regarded as the
"genotype" . It gives description about
complete set of genes an organism.
If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with
uppercase letter F, the other allele is responsible for coding of white flowers
symbolized with Lowercase letter" f "
There are three possible genotypes which could be featured for Different population of a sweet pea, which are
✓FF
✓Ff
✓ ff.
Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed size in the F1 progeny. She then backcrosses the F1 plants to one of the parental varieties and measures seed size in the backcross progeny. The grower finds that seed size in the backcross progeny has a higher variance that does seed size in the F1 progeny. Explain why the backcross progeny are more variable.
Answers
Answer:
The F1 progeny is completely heterozygous for the loci of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single locus, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).

What advantages does wifi applications of waves have over the previous technology?
Answers
Under the IEEE Wi-Fi standards, the available frequency bands are split into several separate channels. These channels overlap in frequency, and therefore Wi-Fi uses channels that are far apart. Within each of these channels, Wi-Fi uses a “spread spectrum” technique in which a signal is broken into pieces and transmitted over multiple frequencies. Spread spectrum enables the signal to be transmitted at a lower power per frequency and also allows multiple devices to use the same Wi-Fi transmitter. Because Wi-Fi signals are often transmitted over short distances (usually less than 100 metres [330 feet]) in indoor environments, the signal can reflect off walls, furniture, and other obstacles, thus arriving at multiple time intervals and causing a problem called multipath interference. Wi-Fi reduces multipath interference by combining three different ways of transmitting the signal (in a method developed by Australian engineer John O’Sullivan and collaborators). The popularity of Wi-Fi has grown steadily. Wi-Fi allows local area networks (LANs) to operate without cables and wiring, making it a popular choice for home and business networks. Wi-Fi can also be used to provide wireless broadband Internet access for many modern devices, such as laptops, smartphones, tablet computers, and electronic gaming consoles. Wi-Fi-enabled devices are able to connect to the Internet when they are near areas that have Wi-Fi access, called “hot spots.” Hot spots have become common, with many public places such as airports, hotels, bookstores, and coffee shops offering Wi-Fi access. Some cities have constructed free citywide Wi-Fi networks. A version of Wi-Fi called Wi-Fi Direct allows connectivity between devices without a LAN. Radiotelegraphy, radio communication by means of Morse Code or other coded signals. The radio carrier is modulated by changing its amplitude, frequency, or phase in accordance with the Morse dot-dash system or some other code. At the receiver the coded modulation is recovered by an appropriate demodulator and the code groups are converted into the corresponding symbols. In many instances the symbols are generated by a computer and modem rather than with a manual telegraph key.

Where do majority of tornadoes occur in the United States?
Answers
Answer:
central united states
Explanation:
mainly in this area because of cold air coming in from canada and warmer air coming from the gulf of mexico meeting and causing tornados.
Answer:
A majority of tornadoes that occur in the United States, occur in the Midwest and Southeast region of the United States.
Explanation:
Tornadoes can impact just about every U.S. state, but the majority of these storms are concentrated in states throughout the Midwest and Southeast. In fact, of the average 1,137 tornadoes that occur in the United States each year, 64% of them form in states located in “Tornado Alley” and “Dixie Alley”, two regions with a disproportionately high frequency of tornadoes due to atmospheric conditions that persist for long stretches of the year.
With an average of 140 tornadoes annually, Texas is the most tornado-prone state in the U.S., followed by Kansas with 80 and Florida with 59, according to National Oceanic and Atmospheric Administration data.

Which of the following best describes the difference between population size and population density?
A. Population density measures the abundance of an organism, whereas population size measures the distribution
B. Population size measures the abundance of an organism, whereas population density measures the distribution
C. Population size measures abundance, but population density measures how rapidly the size changes
D. Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population
E. None of these descriptions are correct
Answers
Population size refers to the number of individuals, while population dendity refers to the number of individuals per unit of area or volume. The correct option is E. None of these descriptions are correct.
------------------------------------------------
Before answering the question, let us review the concepts of population size and density.
Population size refers to the number of individuals composing a population.Population size might determine the destiny of the population.
A small population has more chances to get extinct than a bigger-sized population.
Density refers to the average number of individuals of the same species per unit of area or volume. This measure may be more significant than population size.
To estimate population density there are two possible methods: Direct methods and indirect methods.
Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes.
According to these concepts, the correct option is E. None of these descriptions are correct.

Answers
Complete question:
The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.
Genotype Observed frequency
A → 18 individuals
B → 55 individuals
C → 27 individuals
Do these contradict the genetic model?
Use a 0.05 level of significance.
Determine the chi-square test statistic.
Answer:
Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.
Explanation:
Available data:
Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individualsSo, let us first state the hypothesis:
H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25% H₁ = the population is not in equilibriumNow, let us calculate the number of expected individuals, according to their expected ratio.
4 -------------- 100% -------------100 individuals
1 --------------- 25% -------------X = 25 individuals A
2 -------------- 50% -------------X = 50 individuals B
1----------------- 25%--------------X = 25 individuals C
A B C
Observed 18 55 27 Expected 25 50 25 (Obs-Exp)²/Exp 1.96 0.5 0.16(Obs-Exp)²/Exp
A) (18 - 25)²/25 = 49/25 = 1.96
B) (55 - 50)² / 50 = 25/50 = 0.5
C) (27 - 25)²/25 = 4/25 = 0.16
Chi square = X² = Σ(Obs-Exp)²/Exp
∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A. E are the Expected individuals: 10 in each chamberX² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62
Freedom degrees = 2
Significance level, 5% = 0.05
Table value/Critical value = 5.99
X² < Critical value
2.62 < 5.99
These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.
