Question: What is an adaptation?
Answer:
an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment
Explanation:
An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
Using compaction and cementation explain why sedimentary rocks are not just a loose pile of sand and rocks.
Compaction and Cementation They are compacted, reducing the available pore space and expelling much of the pore-water. Dissolved minerals in the ground water precipitate (crystallize) from water in the pore spaces forming mineral crusts on the sedimentary grains, gradually cementing the sediments, thus forming a rock.
Through compaction and cementation, minerals form a crusts on the sedimentary rocks which are no longer just a loose pile of sand and rocks.
What are sedimentary rocks?Sedimentary rocks are formed from the pre-existing rocks or pieces of or fossils of living organisms. They form from the deposits which accumulate on the surface of Earth. Sedimentary rocks often have distinctive layering or bedding over Earth.
Dissolved minerals present in the ground water precipitates from the water surface present in the pore spaces forming mineral crusts on the sedimentary grains, which gradually undergo cementing the sediments, which thus lead to formation of a rock.

what are the consequences of overdrawal of water?
Answer:
As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.
Number 8. was colorblind just like his father: Where did the son at 8 get his allele for colorblindness?
Answer:
son 8 inherited it from her.
Explanation:
Given that Son 8's mother is a carrier of the blindness allele
Assuming that the father is colorblind due to a genetic mutation, there are a few possible scenarios for how the son inherited the allele for colorblindness.
What is genetic inheritance?Genetic inheritance is the study of how certain inherited traits are passed down from generation to generation.
Assuming the father is colorblind due to a genetic mutation, there are a few possibilities for how the son inherited the colorblind allele:
His father's colorblindness allele was passed down to his son. The son in this case inherited the mutation from his father.The mother carries the colorblindness allele, which she passed on to her son. In this case, the son inherited the mutation from his mother, who is not colorblind but carries the gene.The colorblindness mutation is present in both the mother and father, and the son received one copy from each parent. This is a less likely scenario, but it is possible if both parents carry the gene.Thus, in any of these scenarios, the son inherited the allele for colorblindness from one or both of his parents.

The order of the genes on a plant chromosome is A, B, C, where A and B are located 10 cM apart and B and C are located 3 cM apart. What is the probability that the trihybrid ABC/abc will produce any kind of recombinant gamete
Answer:
Double Crossing-over prob = 0.3% Simple Crossing-Over prob A-B = 9.7%Simple Crossing-Over prob B-C = 2.7%Total Crossing-Over prob = 12.7%Explanation:
Available data:
order of the genes on a plant chromosome is A, B, CA and B are located 10 cM apartB and C are located 3 cM apartThe genetic distance = recombination frequency x 100 expressed in map units (MU). One centiMorgan (cM) equals one map unit (MU).
We can use the provided map with the distances between genes to predict the occurrence of any kind of recombinant gamete.
We know that there is a probability of a simple crossing over to occur between genes A and B, or between genes B and C. And we also know that there is a probability of double crossing-over occurrence.
We can get the probability of the double-crossing over by multiplying the recombination frequencies between A-B and B-C. So,
DCO prob = recombination frequency A-B x recombination frequency B-C
= 0.1 x 0.03 = 0.003 = 0.3%
DCO prob = 0.3%
According to this, we would expect to find
0.15% AbC0.15% aBcNow we need to know what are the probabilities of getting a simple crossing-over, SCO. We already have the genetic distances between genes. 10 cM equals 0.1 of recombination frequency, and 3cM equals 0.03 of recombination frequency. However, we can not estimate the probabilities of simple crossing over using only this information, because this data is including the probabilities of the double crossing-over occurrence. So we need to substrate this percentage.
SCO prob A-B = 0.1 - 0.003 = 0.097 = 9.7%
SCO prob A-B = 9.7%
we would expect to find
4.85% Abc4.85% aBCSCO prob B-C = 0.03 - 0.003 = 0.027 = 2.7%
SCO prob B-C = 2.7%
we would expect to find
1.35% ABc1.35% abCThe total Crossing-over probability, TCO, is then the sum of all the crossing over probabilities,
TCO= SCO A-B + SCO B-C + DCO
TCO prob = 9.7% + 2.7% + 0.3%
TCO = 12.7%

How did diffusion of the perfume change with an increase of concentration
Answer:
Explanation:
Diffusion is trigger by concentration differences.
When perfume is sprayed in the room, the molecules of the perform come in contact with the air molecules and tend to mix well with air molecules, this molecules then spread and move from area of lower concentration to an area of higher concentration. Because the molecules are in constant motion, they move to area where there is high concentration.

b) Explain why a leaf cannot be tested for starch by adding iodine solution directly.
Answer:
Due to presence of waxy layer.
Explanation:
A leaf cannot be tested for starch by adding iodine solution directly because waxy cuticle covering the leaves that prevents the penetration of iodine in the leave cells. First, the waxy layer should be removed by boiling the leaves that causes disruption in the cell membranes that make easier for the iodine to penetrate in the leave cells so that's why iodine can not be tested for starch directly.
