What happened to the peppered moths of Manchester, England when industry boomed and coal smoke darkened the light grey bark of the trees?
Hey there!
The peppered moths actually turned black as a result of the soot from factories changing the color of the bark on the trees - their habitat.
They all turned black because the ones during the Industrial Revolution were turned black, and this caused a mutation, so when they bred with others, their offspring turned black, causing them to ALL turn black.

What are some freshwater systems and what do they all share in common?
Answer:
There are three main types of freshwater biomes: ponds and lakes, streams and rivers, and wetlands. We'll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters, not moving like rivers or streams.
Explanation:
Water is broadly classified as fresh and salt water. Examples of fresh water systems I know are;
Ponds, rivers, lakes, and reservoirs.Similarities among all these sources of water are the fact that;
They are all small bodies and have a low amount of salt. They are also shallow and not dense.Fresh water makes up about 1 percent of the world's surface area whereas salt water which is found in large bodies of water takes more than 95% of the earth's surface area.
Smaller bodies of water are mainly freshwater. These are shallow, have low salt content, and are not quite dense. Large bodies like oceans and seas are known to have high salt content.

En un cultivo de células vegetales se introdujo una mutación genética que produjo como consecuencia la incapacidad de estas células para polimerizar todo tipo de moléculas de glucosa. ¿Que consecuencias podrían haber para estas células?
Explanation:
Aun cuando los procesos de replicación del material genético son muy precisos, no son perfectos, por lo que pueden producirse errores que generan cambios. Una mutación es una variación espontánea o inducida del genoma, un cambio permanente y heredable en la secuencia del ADN, en nucleótidos, o bien en la disposición del ADN en el genoma.
Estos cambios o mutaciones se deben a alteraciones de la información genética. Las consecuencias dependen entonces del nivel de afectación: desde cambios en la secuencia nucleotídica, en los genes o los productos génicos, hasta en los tipos celulares involucrados.
Todos los seres vivos cuentan con sistemas de verificación y reparación de los procesos celulares. En el caso de la replicación del ADN existen sistemas de reparación específicos y bien coordinados, pero en ocasiones las lesiones del ADN que escapan a esta verificación serán las causantes de ocasionar mutaciones; por lo tanto, la efectividad de la lesión dependerá tanto de la tasa de división celular, como de la eficiencia de los mecanismos de reparación contra el aumento en las lesiones al ADN. Cuando ambos factores están incrementados, el resultado será una mayor generación de mutaciones o mutagénesis (y carcinogénesis).

Answer:
t= log2(2048)
The logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x. In this case:
[tex] {t}^{2} = 2048[/tex]
[tex]t = \sqrt{2048} = 45.3h[/tex]

if you cross Bb with bb what's is the genotype ratio?
Answer:
Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.
Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.
Explanation:
Answer:
I don't know about the ration but it's going to be 25% chance for them to have an offspring with blue eyes as there is a presence of a dominant allele
Which statement below applies to the evolutionary thoughts of Lamarck ONLY?
Organisms evolve over time
There are variations in populations which causes those that are best adapted to
live and reproduce successfully.
The most fit organisms survive to pass along beneficial these traits to their
offspring, resulting in more individuals each generation having the desired trait
Organisms acquire traits they need and then pass down these acquired
characteristics that they had obtained in their lifetime to their offspring.
Answer:
The most fit organisms survive to pass along beneficial these traits to their
offspring, resulting in more individuals each generation having the desired trait
Explanation:
Color-blindness results from both the expression of a single recessive sex-linked allele (b.)
Which of the following is a genotype of a colorblind male?
XbY
XBXB
XBY
XbXb
Answer:
XbY
Explanation:
because the question asks genotype of a male, the chromosomes would be XY, so XBX and XbXb can be eliminated leaving only XBY and XbY. XBY is incorrect because the question states that colorblindness is represented by lowercase b, so the correct answer is XbY.
Polygenic inheritance is determined by multiple _______ located at different loci on different chromosomes.
Answer:
Polygenic inheritance is determined by multiple Genes located at different loci on different chromosomes.
Polygenic inheritance happens when an individual posses quantitative traits that become a variation compared to the parent's traits.
This phenomenon happens due to the combination of two or more genes that resulted in the characteristics that considered as the combination of both parents' characteristic.
Explanation:
Answer:
Genes.

Explanation:
glucocorticoids are steroid hormones that control cellular responses through several different signaling pathways. One of the signaling pathways involves the glucocorticoid receptor, an intracellular protein that is activated by binding to a glucocorticoid molecule. A simplified model of the glucocorticoid receptor signaling pathway is represented in Figure 1.
Which of the following statements best predicts the effect of a mutation that results in a loss of the glucocorticoid receptor’s ligand binding function?
