How does acid rain (deposition) form and travel to effect the environment?
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

Which of the following descriptions is MOST plausible for an ancestor of bats? An animal with-
A: two limbs and webbed toes.
B: a long tail that ate insects and lived in forests.
C: four limbs and a membrane consistent with gliding.
D: four fins that glided through the water.
Answer:
C
Explanation:
Four limbs and a membrane consistent with gliding are the structures found in ancestors of bats. Therefore, option (C) is correct
What is patagium?A membrane called the patagium helps animals glide or fly. Bats, birds, dromaeosaurs, pterosaurs, gliding mammals, flying lizards, and flying frogs have the structure. The uropatagium (particularly in bats) or interfemoral membrane connects an animal's hind limbs.
Bats' wing skin extends from the abdomen to the tip of each digit, connecting the forelimb to the body. Bat patagiums have four parts:
Propatagium: neck-to-first-digit patagium.Dactylopatagium: digits.Plagiopatagium: between final digit and hindlimbs.Uropatagium: posterior flap between hindlimbs.Therefore, option (C) is correct.

Which type of human population is characterized by the lag phase, being able to raise crops and domesticated animals, but having over farming methods that lead to soil eorion and food shortages?
Answer:
Rural population.
Explanation:
The rural population of humans is characterized by the lag phase because they are linked with farming of crops and domesticated animals. This population is responsible for the soil erosion and food shortages over the country because they are the producers of everything for the food industry. Due to farming methods, soil erosion occurs that leads to the depletion of nutritive part of the soil that causes less productivity of the crop and as a result food shortage occur.

What process contains the enzymes that break the chemical bonds in your food in order to create usable energy?
Answer:
Cellular respiration
Explanation:
This is because cellular respiration is an aerobic process where the chemical bonds in food are broken down to release energy. This process produce energy which are useful for the body cells. Cellular respiration help to break down glucose. Glucose and oxygen are converted to carbondioxide and water and energy is released which form ATP.
For each sequence of DNA is shown. Write the complementary RNA sequence underneath the letters, then use the codon chart to determine the amino acid sequence. DNA: ACA TTT CAG ACC GTG
Answer:
If youre doing the complementary RNA strand of DNA is would be for example
DNA: A T C G G
RNA: U A G C C
*remember that in RNA the A is complementary U instead of T*
so when you get that done you use every three letters of the *RNA* sequence and match it to the codon chart

Which sequence furthers scientific knowledge? Hypotheses generate a scientific question, leading to observations, which can be tested through an experiment. Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment. Hypotheses generate a scientific experiment, leading to observations, which can be tested through a question. Observations generate a scientific experiment, leading to a hypothesis, which can be tested through a question.
Answer:
The correct answer is - Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Explanation:
In any scientific knowledge development process, scientists need to follow the scientific process in a particular sequence that helps in developing and testing a hypothesis.
The sequence has:
observation: Observation requires you to pay attention to occurrences around
Forming question: on the basis of observation form a question about why that occurrence happens.
Hypothesis formation: The hypothesis is your initial prediction on why that happens.
Experiment: The experiment is being done in order to collect data and analysis so you can test your hypothesis

Test One: If I breed a short fur, FF female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Since all these offspring only have one trait for long fur, this trait stays hidden in their DNA and is not expressed in their phenotype. All the offspring will have short fur.
Test Two: If I breed a short fur, Ff female with a short fur, Ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Test Three: If I breed a long fur, ff female with a long fur, ff male, then I will expect to see (all short fur; some short and some long fur; all long fur) offspring.
Answer:
test two:
some short fur and some long fur will be seen.
this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.
test three:
all long fur is seen.
since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.
Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.
According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene
• dominant allele F codes for short fur
• recessive allele f codes for long fur
We can also assume that the gene expresses complete dominance.
What is complete dominance?It is the inheritance pattern in which the dominant allele completely masks the recessive allele.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.
Many genes show complete dominance.
Cross 1:
Parentals) FF x Ff
F1) 100% short fur
All short fur
Cross 2:
Parentals) Ff x Ff
F1) 1/4 FF + 1/2 Ff / 1/4 ff
75% short fur + 25% long fur
Some short fur, and some long fur
Cross 3:
Parentals) ff x ff
F1) 100% long fur
All long fur

How do large bodies of water affect the climate of a region?
Answer:
