What conclusion can be drawn from the diagram to support the theory of evolution?
Man evolved from gorillas which evolved from chimpanzees.
Gibbons are most closely related to man because of similarities in their skeletal structure.
Orangutans have a larger jaw size than chimpanzees, allowing them to have a more carnivorous diet.
Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food.
Answer:
Following conclusion could be drawn from the given diagram;
Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food.

What is theory of evolution?The theory of evolution is a scientific explanation for the diversity of life on Earth. It explains how species of organisms change over time through the processes of natural selection, genetic variation, and inheritance.
The theory of evolution is supported by evidence from many different areas of science, including genetics, geology, comparative anatomy, and biogeography. The theory proposes that all species, both past and present, are related through a common ancestry and have evolved over millions of years through a process of gradual change and adaptation. It is considered one of the most fundamental and well-supported scientific theories in biology.

- What is the geocentric model of the
universe?
a) The Theory of Evolution
b) Newton's Laws of Motion
c) The belief that Earth is at the center of our solar system
d) Superstition
Answer:
I believe C,
Explanation:
The geocentric model of the universe maintained that the Earth was at the center of everything in the solar system. In it, the Sun and planets orbited around our planet. Many odd and elaborate adaptations were required to make this model agree with observations. This problem increased, as our our observations got more accurate.
The geocentric model was superseded by the heliocentric model, in which the planets all orbited the Sun. The Heliocentric model was eventually able to show that the positions of the planets over time were much more convincingly, and simply portrayed by it, than by the former model.
Apologizes if I'm wrong/

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
a) The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
b) The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
c) The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
d) The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.

What are chromosomes? When do chromosomes form?
Answer:
Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Look at the overall view of the onion root tip. Which phase does it look like most cells are in? Why are most cells in this phase?
Hello. You did not present the image to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
I believe you are looking at cells from the tip of the root, in an experiment where the tip of the root of the onion was cut. To redo the tip of the root, the onion cells will undergo mitosis, which is the cell division where a cell originates from two identical cells.
Mitosis has five phases and all of them can be seen in the onion root cells according to the following characteristics:
1. Interphase: it is the moment when the cells increase in size and intensify their metabolic activity. The cells of the onion root will be in this phase when they appear as a completely dark and filled circle.
2. Prophase: The chromosomes condense and become visible and the cell membrane is flawed. In the cells of the onion root, you will be able to see this phase in cells that appear as an irregular circle, with a tangle of lines scattered inside.
3. Metaphase: The chromosomes condense further and connect to the spindle lines that are in the center of the cell. In the onion root cells, you will identify this phase in circles with a tangle of lines that are concentrated in the center of the cells.
4. Anaphase: The centromeres are separated and the sister chromatids migrate to the poles of the cell. You will be able to see this phase in cells that have a concentration of lines at both ends of the cell.
5. Telophase: the chromosomes are decondensed and the cell membrane is formed again while the cell separates into two. You will see this phase with the presentation of two cells.
To improve your understanding, the attached figure below shows how the cell appears in each phase.

When a volcano erupts, such as the Kilauea volcano in Hawaii, what do you think happens to the surrounding ecosystem? Explain how you think disruptions to the physical and biological components of the ecosystem would affect local populations.
Answer:
the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life
The volcanic eruption of Kilauea volcano in Hawaii can have prolonging effects on the water and air quality, and in the livelihoods of the natives living in the surrounding region.
• The volcanic ash has been known to coat the highways, collapse roofs, ground airplanes, and put the natives at threat of developing respiratory ailments.
• The instantaneous influence of the eruption would be the destruction of wildlife and plant species.
• The pyroclastic flows, lava flows, and Kilaeua's discharge of toxic sulfur dioxide can lead to famine and ultimately the loss of livestock and other animals.
Thus, serious consequences would result due to the eruption of Kilauea volcano.

Why would we not have animals without plants?
try to create an original enough answer! ^^ Thank you!
Answer: Humans and animals use the oxygen (O2) in the air for their energy process and produce CO2 as waste. A plant does the exact opposite. ... If there were no plants on the planet we wouldn't be able to breathe. Humans in particular, however, also produce other waste
Explanation:
Air in soil is essential to provide oxygen to plant roots.
True
False
Answer:
true
Explanation:
Particularly, soil air is needed by many of the microorganisms that release plant nutrients to the soil. ... Since plant roots require water and oxygen (from the air in pore spaces), maintaining the balance between root and aeration and soil water availability is a critical aspect of managing crop plants.

And, on which organelle?
Answer:
It occurs in the organelle ribosome which can either be located in the cytoplasm or in the rough endoplasmic reticulum
