Human adult hemoglobin is a tetramer containing two alpha (α) and two beta (β) polypeptide chains. The α gene cluster on chromosome 16 and the β gene cluster on chromosome 11 share amino acid similarities such that 61 of the amino acids of the α-globin polypeptide (141 amino acids long) are shared in identical sequence with the β-globin polypeptide (146 amino acids long). Part A How might one explain the existence of two polypeptides with partially shared function and structure on two different chromosomes
Answers
Answer:
The similarity between the amino acid sequences between the two polypeptide chains indicates that some time ago there was the existence of only one sequence, however, later on, the phenomenon of duplication took place. Due to duplication, the emergence of two similar sequences took place adjacent to each other in one chromosome.
Post duplication it was due to chromosomal aberration that the two sequences got positioned on distinct chromosomes. This resulted in the positioning of the alpha polypeptide chain on chromosome 16, and on chromosome 11 beta polypeptide chain got positioned.
However, due to mutations, the two polypeptide chains do not exhibit complete similarity. Post duplication to the current time both the sequences would have gone through various mutations resulting in the reduction of the entire similarity of the genes.

True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
Answers
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

How can a poly genic trait be easily identified
Answers
Answer: The presence of the polygenic trait masks the other possible alleles involved. There are only two possible phenotypes for the trait. The graphing of the possible phenotypes results in a bell curve. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.

Define homeostasis asap pleaseee
Answers
Answer: to be balanced
Homeostasis is the ability of an organism or system to maintain a stable internal environment despite changes in the external environment. The term was coined by Walter Bradford Cannon in 1930 and comes from the Greek words "homeo," meaning "similar," and "stasis," meaning "standing still."
Homeostasis applies to the body's physiological processes, such as metabolism, temperature regulation, fluid balance, and hormone secretion. These processes involve a series of feedback mechanisms that sense changes in the body and trigger responses to restore balance. For example, when the body's temperature rises above a certain level, thermoreceptors in the skin and hypothalamus signal the sweat glands to produce sweat and the blood vessels to dilate, which helps to dissipate heat and bring down the temperature.
Homeostasis also applies to psychological processes, such as mood, stress, and arousal. These processes involve the brain's regulatory systems, such as the limbic system, the autonomic nervous system, and the endocrine system. These systems work in tandem to respond to internal and external stimuli, and regulate emotions, instinctual drives, and cognitive processes.
The concept of homeostasis is important in understanding health and disease. When homeostasis is disrupted, the body or mind may experience dysfunction, disease, or pathology. For example, chronic stress can lead to an overactive HPA axis and the release of cortisol, which can suppress the immune system and lead to inflammation and disease. Diabetes is also a condition where the body's homeostasis is disrupted, resulting in high blood glucose levels and impaired glucose metabolism.

a) Debris from the impact coalesced to form the moon.
b) The Earth gained mass from the impact.
c) The impact caused the surface of the Earth to melt.
d) The impact caused the Earth to slow its rotation.
Answers
According to a current theory, a planet roughly the size of Mars struck Earth during its formation. Debris from the impact coalesced to form the moon.
What is the great impact theory?The giant impact hypothesis, the prevailing theory accepted by the scientific community, contends that the moon developed as a result of an object slamming into the early Earth. Earth originated from the leftover dust and gas cloud orbiting the newborn sun, just like the other planets.
What are the three theories of the moon's formation?Scientists have proposed various alternative theories, such as the idea that the moon broke away from Earth ("Fission theory"). The moon originated elsewhere in the solar system before being drawn in by the gravity of the Earth ("Capture theory"). The Earth and moon co-formed from the protoplanetary disk ("co-formation") at the same time.

11. The offspring of a cross between two rough-coated animals shows a ratio of three rough-coated offspring to one smooth-coated. Which trait must be dominant?
Answers
Answer:
The rough-coated trait must be dominant. This is because in a cross between two animals that are heterozygous for a particular trait (one dominant allele and one recessive allele), the ratio of dominant to recessive traits in the offspring is typically 3:1. If the smooth-coated trait were dominant, then all the offspring would have that trait, and the ratio would be 0:4 instead of 3:1.

They are like small boxed with lids composed of silica statement best describes the composition of diatom shells.
Option A is correct.
How do diatom shells work?Diatoms are a kind of freshwater green growth with siliceous shells (made of silica). They live in "glass houses" literally. A diatom's shell is made up of two sections that are different sizes and can be wedge- or round-shaped.
What purpose do diatom shells serve?The natural material of diatom shells, which are made of silicon dioxide and can theoretically be made in any quantity, has regular patterns of pores that penetrate their surface. Diatom shells have the potential to be utilized as low-cost, highly effective drug carriers, sensor devices, or other microdevices due to their characteristics.

does coal releases carbon dioxide into the atmosphere?
Answers
Answer:
yes
Explanation:
Coal is an important source of energy in the United States, and the Nation's reliance on this fossil fuel for electricity generation is growing. The combustion of coal, however, adds a significant amount of carbon dioxide to the atmosphere per unit of heat energy, more than does the combustion of other fossil fuels
Fossil fuels release greenhouse gases into the atmosphere, which increases levels of carbon dioxide and other gases, trapping heat, and contributing to global climate change. This means that coal does release greenhouse gases, like carbon dioxide and nitrous oxide, into the atmosphere.

What is the dew point if the dry bulb temperature is 20 C and the relative humidity is 17 %?
Answers
The dew point if the dry bulb temperature is 20°C and the relative humidity is 17 % is 1.6°C.
Dew point is the temperature at which air becomes saturated with water vapor and begins to condense. The dew point is a significant meteorological parameter that represents the measure of atmospheric humidity. The dew point is a critical component in calculating relative humidity and heat index.
It also plays a crucial role in predicting the possibility of dew, frost, and fog. Given the dry bulb temperature of 20 C and the relative humidity of 17%, we can calculate the dew point as follows:First, find the saturation vapor pressure using the equation:Es = 6.11 × 10(7.5T / (237.7 + T))where T is the temperature in degrees Celsius.So, Es = 6.11 × 10(7.5 × 20 / (237.7 + 20)) = 23.48 mmHg.
Next, find the actual vapor pressure using the formula: E = RH/100 × E_s where RH is the relative humidity as a percentage. So, E = 17/100 × 23.48 = 3.99 mmHg. Finally, we can calculate the dew point using the formula: Td = (237.7 × log10(E/6.11)) / (7.5 - log10(E/6.11))Td = (237.7 × log10(3.99/6.11)) / (7.5 - log10(3.99/6.11)) = 1.6°C. Therefore, the dew point is 1.6°C.
