Answer:
40% is the percentage of the gamma allele in the population.
Explanation:
Available data:
Two alleles, delta and gamma60% of the alleles in the southern GA population are the delta alleleWhat is the percentage of the gamma allele in the population?
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the same way, the sum of genotypic frequencies equals 1, this is
p² + 2pq + q² = 1
Being
p the dominant allelic frequency, q the recessive allelic frequency, p² the homozygous dominant genotypic frequency q² the homozygous recessive genotypic frequency 2pq the heterozygous genotypic frequencyIf the percentage of delta allele in a population is 60%, this means that its frequency is 0.6. By clearing the equation p + q = 1, we can calculate the gamma allele frequency. This is:
p + q = 1
0.6 + q = 1
q = 1 - 0.6
q = 0.4
Then the percentage of gamma allele in the population is 40%.
We can also think about it like this:
If the sum of the allelic frequencies equals 1, then 1 is 100% of the allelic frequencies. And if the percentage of delta allele in a population is 60%, then 40% is the percentage of gamma allele.
What do eukaryotes cells have that prokaryotes do not have

how can digestive enzymes assist in breaking macromolecules down into smaller subunit?
Answer:
Chemical digestion
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.

Answer:demand for resources such as fossil fuels
Explanation:
Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.
Thus, The breakdown of buried, carbon-based organisms that perished millions of years ago produces fossil fuels. They produce deposits rich in carbon, which are taken out and burned to provide energy.
They presently provide about 80% of the world's energy and are non-renewable. A vast array of items, including plastic and steel, are also produced using them. Coal, oil, and gas are the three forms of fossil fuels.
Global warming is mostly caused by emissions from fossil fuels, according to the Intergovernmental Panel on Climate Change (IPCC). 89% of the world's CO2 emissions in 2018 came from industry and fossil fuels.
Thus, Building large manufacturing facilities can affect ecosystems by increasing the demand for resources such as fossil fuels.

Which of the following is true? Group of answer choices In the brain, neurons are more abundant than neuroglia. An action potential never occurs in dendrites. When a neuron is stimulated, Na+ gates open and allow Na+ to exit the cell. In a myelinated fiber, only the initial segment in the trigger zone has voltage-regulated channels. Norepinephrine is a neuropeptide.
Answer:
The true statements are:
An action potential never occurs in dendrites.
Norepinephrine is a monoamine.
Explanation:
In the following question only two statements are true that are; an action potential never occurs in dendrites as it occurs in nerves to send signals from cell body and axon and transmit it.
The second correct statement is Norepinephrine is a monoamine as these are particular neurotransmitters dopamine, serotonin, also known as catecholamines sometimes.
Thus, the correct answer is :
An action potential never occurs in dendrites.
Norepinephrine is a monoamine.
Which statement best explains why fermentation occurs in mammals? It enables mammals to generate additional ATPATP in an oxygen‑rich environment. It breaks down lactic acid to generate a small amount of ATPATP under anaerobic conditions. It generates ethanol, which can be used as an alternative source of energy. It produces an acid that maintains blood pH within a narrow range. It allows glycolysis to continue under anaerobic conditions by replenishing NAD+NAD+ .
Answer:
The last option.
Explanation:
Fermentation/ Anaerobic respiration is important to supply ATP in the absence of oxygen.
In the presence of oxygen, glycolysis, Kreb's cycle and oxidative phosphorylation happen to provide about 32 ATP molecules. In its absence, only glycolysis can take place because it's the only step that doesnt need oxygen, to give a net supply of 2 ATP.
Even though glycolysis doesn't need oxygen, it needs NAD, and if the reduced NAD doesn't lose its hydrogens via oxidative phosphorylation, pyruvate (the end product of glycolysis) becomes the recipient of the hydrogen.
Pyruvate gets reduced to lactate.
The correct answer as to which best explains why fermentation occurs in mammals would be that it breaks down lactic acid to generate a small amount of ATP under anaerobic condition.
Aerobic respiration takes place in 3 steps:
Glycolysis: during which glucose is converted into pyruvate molecules with 2 ATP and 2NADH molecules produced.Citric acid cycle: during which pyruvate molecules from glycolysis are converted to CO2 with ATP, NADH, and FADH2 generatedElectron transport chain: during which the NADH and FADH2 produced in citric acid cycle are used to generate ATP.When oxygen becomes inadequate during rigorous activities in human cells, pyruvate molecules cannot proceed to the citric acid cycle due to lack of oxygen. Instead, the pyruvate molecules are converted to lactic acid through fermentation to generate 2 molecules of ATP.

What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Answer:
The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".
Explanation:
In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

Rushes and frogs would be found along the edges of water bodies, squirrels would be found within appropriate environments, which would be acorn tree forests and orchid plants also occupy a particular tree.
The correct option is E.
What is random dispersion?
In random dispersion, individuals are distributed randomly, without a predictable pattern. An example of random dispersion comes from dandelions and other plants that have wind-dispersed seeds.
Is random dispersion rare?In natural populations, random dispersion is rare, while clumped dispersion, which we'll focus on in this lesson, is the most common pattern. Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals.

The color varieties of sunflower pollen are determined by two interacting loci: A_B_ gives orange pollen, aaB_ gives yellow, and _ _bb produces cream colored. Assume that two fully heterozygous plants are crossed. Give the phenotypes (with frequencies) of the offspring. What type of gene interaction would account for these results?
Answer:
This is an illustration of epistasis type of gene interaction.
Explanation:
On crossing AaBb * AaBb, the offspring produced are mentioned in the Punnett square given in the attachment below. Based on the Punnett square, the phenotypic ratio will be 9 (orange): 4 (cream) : 3 (yellow).
The given case is an illustration of the epistasis kind of gene interaction. When two or more distinct gene loci take part in the formation of similar phenotype, however, not additively is termed as epistasis, that is, it is the non-allelic association between the alleles situated at a distinct gene locus. In the phenomenon of epistasis, one of the gene loci modifies or masks the phenotype of a second gene locus.

Answer:
Interphase
Explanation:
Interphase is made of G1, S and G2 phases. In G1, cells basically fuel up on necessary nutrient and see if nutrients are available to sustain a dna replication. Then in S phase, DNA replicates. Then in G2, cell checks if there's any error in replication, if none detected some more nutrient checks are performed and then cell proceeds to mitosis.
