Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats.
On the western peninsula, the changing climate means different weather is turning sheets of snow and ice into a land of rain and mud. Older penguins are equipped with waterproof layers of feathers allowing them to move swiftly in the water, and also allowing them to stay warm on land.

Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.
6.Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

Which problem do you think contributes most to water scarcity?
Answer:
QUESTION:
Which problem do you think contributes most to water scarcity?
ANSWER:
Water shortages may be caused by climate change, such as altered weather patterns including droughts or floods, increased pollution, and increased human demand and overuse of water. A water crisis is a situation where the available potable, unpolluted water within a region is less than that region's demand.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 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.

You cross nonpure tall plants (Tt) and produce 200
offspring. Which of the following statements about
the offspring is correct?
A. All of the offspring will definitely be tall.
B. 150 of the offspring will definitely be tall.
C. There is a 75% chance that each offspring
will be tall.
O D. There is a 25% chance that each offspring
will be tall.
Answer:
C is the best answer
Explanation:
the dominate trait is in 3 of the four boxes
There is a 75% chance that each offspring will be tall. Therefore option C is correct.
When you cross non-pure tall plants (Tt), you are dealing with a heterozygous genotype, meaning the plants have one dominant (T) and one recessive (t) allele for the height trait.
The dominant allele (T) is responsible for the tall phenotype, while the recessive allele (t) leads to short plants. In this case, 75% of the offspring will likely receive the dominant allele from at least one parent (Tt or TT) and therefore be tall.
The remaining 25% will inherit the recessive allele from both parents (tt) and be short. This is based on the principles of Mendelian genetics and the Punnett square.
Therefore option C There is a 75% chance that each offspring will be tall is correct.

2. Direct
Explanation:
1. The distance pulled back means you get your answer from the distance pulled back data. Since 50cm is the largest of your given data, that makes the cart go farthest.
2. The farther you pull the band back, the farther the cart will go. Since both increase when you increase the distance you pull the band back, this is a direct relationship.
Some flowers show incomplete dominance. If RR = white and R'R' = red, which phenotypic ratio would
be expected in the o spring of two pink flowers?
Answer:
1 red: 2 pink: 1 white
0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
What is Phenotypic ratio?Phenotypic ratio defined as the relative number of offspring expressing a particular trait or combination of traits, which can be determined by performing a test cross and the frequency of the trait or trait combinations being expressed depending on the genotype of the offspring can be identified.
Phenotypic ratio is expressed as the ratio of different phenotypes present in the progeny of a cross where the ratios are numerical comparisons. For example, if one has three mangoes and two oranges, the ratio of mangoes to oranges will be 3:2.
For above given information, if we cross RR which is white with R'R' which is red, we will get 4RR' offspring which are pink in color. then the ratio will be 0 red: 4 pink: 0 white.
Thus, 0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
