A single gene with two alleles control variation in haemoglobin type in sheep. There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4
Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

Despite the rampant depletion of trees in the natural forest in Ghana,it is still worth using wood as the main construction.Disscuss
Answer:
Hope this helps!
Explanation:
Forest resources support livelihood of people in jurisdictions in which forest is located. However, the forest size is gradually depleting continuously. The lack of information about the specific agents and forces of forest depletion is worrying. This is due to the inter-generational and intra-generational equity notions that affect mankind. As such, there is the need to maintain such resources on a non-declining value basis so as to maintain human welfare over time. Thus, the objective of this study is to empirically examine the determinants of forest depletion in Ghana over the 1970-2012 period in Ghana. This study employs multiple regression concepts to examine the effects of the determinants on forest depletion. The findings of the study indicate that gold extraction for export, population growth and logging increase the rate of forest depletion for the study period. More significantly, population growth reflected in settlement expansion, agriculture purposes, increased use of fuel wood, etc have greater effect on forest loss in Ghana. This suggests that, protection of the forest is necessary and sufficient condition for economic growth. As a result of these, both government and policy-makers need to safeguard the forest estate, by increasing afforestation schemes and also using part of the returns from gold exports to regenerate the forest.

Answer: Part 1: Mass of fundamental succession stars can be pretty much as low as one-10th of the mass of the sun and can be just about as high as 150 to multiple times the mass of the sun. The age of a star relies upon its mass. The temperature of a star is sufficiently high to intertwine the hydrogen inside them to frame a helium iota. Their temperature can be pretty much as high as 15-18 million kelvin.
Part 2: By a long shot the most unmistakable component is the primary arrangement (dim), which runs from the upper left (hot, glowing stars) to the base right (cool, faint stars) of the chart.

A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

If different masses of water are heated to the same temperature, which sample will absorb more energy? Base your argument on the definition of heat and what you learned from the experiment.
If different masses of water are heated to the same temperature, the sample that will absorb more energy will be the mass of water with the greatest amount of water mass, because the larger the material, the greater the amount of heat needed.
What is the specific heat of water?Water has a specific heat of 1 cal/g. ºC This means that the energy of 1 cal is required for a variation of 1 °C in 1 g of water.
With this information, we can conclude that Water's specific heat power is 4.2 joules per gram per Celsius degree or 1 calory per gram per Celsius degree.

write the phenotype and genotype
Explanation:
The concepts of phenotype and genotype are related to genetics.
The phenotype is generally called the external appearance of the living thing, which is formed by the genetic information and environmental effects.
Genotype is the genetic information that an organism carries in its DNA.
For example; Character A is the favorite black color. a is the blue color character.
While the Aa display shows the individual with black eyes in the phenotype, the genotype is expressed as heterozygous dominant black eyes.

f) What are some possible solutions to slowing down or reversing the amount of
carbon humans release into the atmosphere?
In your description, be sure to:
●
Identify a possible solution.
Describe how this solution could help to slow or reverse the amount of carbon
humans release into the atmosphere.
The use of renewable energy sources is a promising solution to slowing down or reversing the amount of carbon that humans release into the atmosphere. By transitioning to cleaner forms of energy, we can reduce our carbon footprint and mitigate the negative impacts of climate change.
There are several possible solutions to slowing down or reversing the amount of carbon that humans release into the atmosphere. One possible solution is the use of renewable energy sources such as solar, wind, and hydroelectric power.
By using renewable energy sources instead of fossil fuels, we can reduce the amount of carbon dioxide that is released into the atmosphere during energy production.
This is because renewable energy sources do not produce greenhouse gases like fossil fuels do. For example, when we burn coal or oil to produce electricity, we release large amounts of carbon dioxide into the atmosphere. But when we use solar panels or wind turbines to generate electricity, we do not release any carbon dioxide.
In addition to reducing carbon emissions, renewable energy sources also have other environmental benefits. For example, they do not produce air pollution like fossil fuels do, which can improve air quality and reduce the negative health impacts associated with air pollution.
