Scientists explain the gap by considering additional sources of helium generation, such as Big Bang nucleosynthesis, which created nearly 75% of all helium in the universe, and intermediate-mass stars, which may produce considerable quantities.

Generally, Scientists account for the discrepancy by considering other sources of helium production, such as Big Bang nucleosynthesis, which produced about 75% of all helium in the universe, and the production of helium in intermediate mass stars, which can produce significant amounts of helium.

2) The three major lines of evidence supporting the Big Bang theory are:

i. The Cosmic Microwave Background Radiation: The discovery of the cosmic microwave background radiation, which is a nearly uniform glow of light coming from all directions in space, supports the Big Bang theory.

ii. The abundance of light elements: The abundance of light elements such as hydrogen, helium, and lithium supports the Big Bang theory.

iii. The large scale structure of the universe: Observations of the large scale structure of the universe, including galaxy formation and clustering, support the Big Bang theory.

The frequency of H1H2 offspring is 0.48 if allele H1 is at frequency 0.60 and allele H2 is at frequency 0.40.

As per the question, the frequency of allele H1 is 0.60, which means [tex]p^{2}[/tex] = 0.60. And frequency of allele H2, [tex]q^{2}[/tex] = 0.40. Now, we know that if two frequncies are equal to 1, the then population is in hardy-Weinburg equilibrium. According to this rule,  

[tex]p^{2}[/tex] + 2pq + [tex]q^{2}[/tex]

Now, we can calculate the frequency of the heterozygote or their offspring, 2pq = 2(0.4) (0.6) = 0.48. Therefore, 0.48 is the frequency of the offspring (H1H2).

All homozygous dominant individuals (AA) and half of the heterozygotes (Aa) are counted since p is the frequency of all dominant alleles (A). Similar to how it counts all homozygous recessive people (aa) and half of heterozygous individuals (Aa) since q is the frequency of all recessive alleles (a). As a result, in a population, [tex]p^{2}[/tex] denotes all homozygous dominant individuals, [tex]q^{2}[/tex] denotes all homozygous recessive individuals, and 2pq denotes all heterozygous individuals. Everything is set to 1 because the total number of people in a population is 1.

The sum of individual supply curves added together reflect the Market supply curve. The link between the cost of an item or service and the volume supplied by all market producers is depicted graphically by the market supply curve.

The market supply curve represents the total quantity of a good or service that all producers in a market are willing and able to provide at each possible price, taking into account the individual supply curves of all firms in the market. The market supply curve slopes upwards as the price of a good or service increases, since producers are incentivized to produce more of the good or service as the price rises. The sum of the individual supply curves represents the market supply curve because it shows the combined effect of all producers in a market on the supply of a good or service.

The dark colored rock pocket mice on the dark rock have light colored bellies as there is no selection for dark bellies by visual predators.

Hence, the correct option is option a) There is no selection for dark bellies by visual predators.

The dark-colored rock pocket mice happened to first appear in a population of light-colored rock pocket mice. They have a genetic mutation which affects their fur color. There is a presence of dark lava rock in the area where they live. The individuals thus change color in order to blend in with the environment.

There is no observed selection for dark bellies by the visual predators. There is a reproductive advantage over having a dark belly. White bellies are a crucial part of camouflage.

--The given question is incomplete, the complete question is

" Why do dark-colored rock pocket mice on dark lava flows have white bellies?

The factors required for biological evolution to occur are (a) genetic variation in the population, (b) natural selection, and (d) a large population.

Biological evolution is the change in inherited traits over successive generations in the population of organisms. There are 5 mechanisms that cause the population exhibits a change from one generation to the next. These are evolution by mutation, genetic drift, gene flow, nonrandom mating, and natural selection. Mutation generates variation. The genetic variation created through a random process of mutation must be present for evolution to occur. The mutation rate is pretty low so the impact is usually not large.

Evolution by genetic drift always happens but the effect is subtle in larger populations. Genetic drift is the change in frequency of an existing gene variant in the population caused by random chance.

Evolution by gene flow involves the movement of genes into or out of a population due to either movement of the individual (migration) or their gametes. When individuals from one population migrate to a different population, they bring those different allele frequencies with them. Two populations will experience changes in allele frequencies.

Natural selection is the process by which a population of organisms adapts and changes. The organism that is more adapted to its environment is more likely to survive and pass on the genes.

Nonrandom mating is a mating system in which organisms prefer to mate with others of the same genotype or different genotypes.

Thus, evolution can occur if there is genetic variation, a large population, and natural selection.

The function of glycocalyces and fimbriae in forming a biofilm is the adhesion of the bacteria to surfaces or to other bacteria.

Certain bacteria are able to evade phagocytic engulfment by white blood cells in the body or by protozoans in soil and water thanks to a protective layer called the glycocalyces. In addition, the glycocalyces make it possible for certain bacteria to colonize, attach to environmental surfaces (such as pebbles, root hairs, or teeth), and resist being flushed away.

Gram-negative bacteria, as well as some Gram-positive bacteria, have hair-like appendages called fimbriae, which play a crucial role in the adherence of the bacteria to surfaces or to other bacteria. Gram-positive bacteria, on the other hand, do not have fimbriae.

If individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles to yield the allele frequency of 0.36 in offspring.

To calculate the allele frequency, the total number of copies of each allele at that particular genetic locus in the population is divided by the number of times the allele of interest is detected in a population.

The frequency of h1h1 offspring in a population is 0.36 if individuals mate at random sampling and h1 has a frequency of 0.60.

In order for a woman to be color eyeless, she must have inherited two  clones of the  sheepish allele, one from her father and one from her  mama .

Since the woman's father is color eyeless, she has one  dupe of the  sheepish allele. For her to pass this allele on to her child, the other parent must also have the  sheepish allele, which isn't the case in this  script. thus, the woman's child would not inherit a  dupe of the  sheepish allele and would not be color eyeless.

The rough endoplasmic reticulum is where the enzyme proteins are originally produced. A vesicle containing such proteins is used to transport them to the Golgi apparatus. The lysosome enzymes are produced by the rough endoplasmic reticulum. The production of lysosomal enzymes takes place in the rough endoplasmic reticulum.

Peripheral proteins are the type of membrane proteins that would likely be most easily removed in a laboratory experiment. The correct answer is C.

Peripheral proteins are loosely associated with the membrane and can be readily dissociated from the membrane surface by changes in temperature, pH, or detergent treatment.

In contrast, integral proteins are firmly embedded in the lipid bilayer of the membrane and are more difficult to remove. Transmembrane proteins span the entire membrane, while channel proteins and gated channels span only part of the membrane and have a hydrophilic (water-soluble) portion that is exposed to the extracellular fluid or intracellular fluid.
