Observing Animals (Image Attached)
Let’s study and compare three animals: a frog, an ancient and extinct mammal-like animal, and an owl. Observe the illustrations, and then answer the questions.
1. How are the bodies of the three animals similar to one another? How are they different?
2. What might these similarities suggest about the common ancestor of these organisms?
Answer: They each have patches on their stomachs. Also, all 3 animals have claws or legs, even though they play different function in each organism, they 3 still share the same characteristics of having claws or legs.

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.

Answer:
When your biceps muscle in your higher arm contracts, it pulls your lower arm in to your shoulder. when it relaxes, your biceps cant push your arm back out. and straightens your arm out.
Explanation:
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.

2. A mouse running away from the sound of an owl's wings is
an example of the mouse's ability to
A. reproduce
B. grow and develop
C. respond to the environment
D. obtain energy
Check Answer
Answer:
C Respond to the environment
A mouse running away from the sound of an owl's wings is responding to the environment.
What are living organisms?
The organism which can breathe, reproduce and have the ability to respond to an environment are some of the characteristics of a living organism.
Reproduction is the ability of an organism which gives similar kinds of organisms. Organisms grow and develop through cell division. Cell division is of two types mitosis and meiosis. Mitosis is an equational division.
The organism can respond to the environment. Mouse running away from the sound of an owl's wing is an ability to respond environment. Different organisms can obtain energy from food sources.
Therefore, A mouse running away from the sound of an owl's wings is responding to the environment.

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.

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
Explanation:
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).

Answer:
1. 50cm
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.
