Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.

1. HYPOTHESIZE: Some human activities change environments in ways that harm both people and other
organisms. Describe one example of this kind of activity.
Answer:
Deforestation is one major human activity that harms both people and organisms. Cutting down trees lowers Earths ability to create fresh air, which leads to more toxic and polluted areas that can cause problems with breathing and even lead to lung cancer. Deforestation can harm other organisms because many animals such as birds, squirrels, and owls, look to the trees for a habitat. However, as we destroy they can cause a decrease in population which leads to an even bigger problem in the food chain.
The force of gravity pulls all objects downwards. Which of these statements is correct about this law of science?
A. It is not supported by observations
B. It can be contradicted by data
C. It requires no further experimentations to determine its existence
D. It is a description in nature that will continue to change
Answer:
C
Explanation:
If you drop something on the ground and watch it fall, you are observing gravity at work, so A is not an option. All data proves this law exists, so B is not an option, and it will not continue to change, as it never has changed, so it is not D.

C

Jason joined a group that would work towards solving the workplace safety issues in his organization. Arrange Jason’s actions according to the stages of development of his group.
Answer:
- Jason asked his fellow group members about their hobbies and interests .
- Jason and another member disagree on what their respective roles should be in the group.
- Jason resolved his differences with the other group members .
- Jason began working with the group members as a complete unit .
Explanation:
The correct order of Jason's actions in the stages of the development of his group would be as mentioned above. After the first step of the formation of the group, the next step is 'storming' in which the ideas are generated. Thus, Jason asks the group members regarding their interests and hobbies as it assists in the generation of effective ideas for problem-solving. The next step would be 'norming' in which the conflicts would arise due to disagreement regarding the respective roles of group members. Then, Jason as a team member would resolve the differences among the team members to reach a common solution. After everyone agrees upon the same idea, Jason can pursue working with the group as a complete unit. These stages are crucial for the effective development of the group and achieve desired results through cooperation and teamwork.

Why xylem and phloem are called complex tissues? How are they different from one another?
Answer:
Xylem and phloem are called complex tissues because they are made up of more than one type of cell working together as a unit. The xylem transports H2O and minerals upward from the roots to the leaves, and is composed of tracheid cells which are dead at maturity (no active nucleus, makes the tree stem hard). If plants don't have xylem, they will stay lower to the ground as it is responsible for making the tree grow upward. The ends of the xylem tubes are tapered (pointed), materials are passed along one cell at a time, and the tubes are narrow and continuous. The phloem transports sugars and proteins downward from the leaves to the stems and storage roots. The cells that make up the phloem are called sieve tubules and companion cells. The companion cells have the nucleus and the sieve tubules contain the cytoplasm.
Explanation:
My teacher helped us remember using the phrase "phloem down the river" because it sounds like 'flowing down the river' (to help remember that phloem transports downward and xylem transports upward.)

What do prokaryotes have in common with eukaryotes?
A. They both have a Golgi apparatus.
B. They both have mitochondria.
C. They both have a nuclear membrane.
D. They both have a liquid cytoplasm.
Answer:
They both have a liquid cytoplasm.
Explanation:
A liquid cytoplasm is an essential part of a cell, in both prokaryotes and eukaryotes. It supports the internal components of the cell, and is the site of many vital cellular processes, such as glycolysis (the first part of cellular respiration).
The Golgi apparatus and the mitochondria are membrane-bound organelles that serve a specific purpose in eukaryotic cells. However, prokaryotic cells do not contain any membrane-bound organelles.
Prokaryotes do have a nucleus, like eukaryotes, but unlike in a eukaryotic cell, a prokaryotic nucleus is not surrounded by a nuclear membrane. Instead, it is just confined to a certain area of the cell, called a nucleoid.
Prokaryotes and eukaryotes both have a nuclear membrane. Option C
What is the commonality?
Prokaryotes and eukaryotes are two large categories of cells with notable variations in their organization and structure. They do, however, have some things in common.
The existence of a nuclear membrane or nuclear envelope is one of the similarities between prokaryotes (such as bacteria) and eukaryotes (such as plants, animals, fungi, and protists). The cell's genetic material, which can be either DNA or RNA, is encased in the nuclear membrane. It divides the cellular components into the nucleus and the remainder.

Why is it important to monitor the pH and other factors in the AgWorks lab
Answer:
To know the actual pH for a particular organism.
Explanation:
It should be understood that in a 6,100-square-foot lab and classroom named AgWorks, students not only learn how to grow food in a controlled environment, but also explore and have the idea of agriculture-related careers.
In this aspect, the monitoring of pH is very important because not all organism survive in acidic and basic mediums, but there are some that required neutral medium for their survival. And this is the reason why to always affirm the particular pH necessary for the survival of a particular organism.

A trait is a distinctive quality or attribute that can be acquired by environmental circumstances, genetic inheritance, or both. In biology, traits are observable and quantifiable qualities of an organism, including its physical characteristics, behaviour, and other traits. For instance, physical characteristics like eye colour, height, and hair texture can all be passed on through genetics.
Hence, the correct option is A.
