Answer:
1. The pieces of evidence that support the theory of evolution include the following:
a. Fossil records/evidence
b. DNA of the organisms
c. Comparative anatomy
2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.
3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.
In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Explanation:
Choose 3 activities that you perform regularly and explain the role(s) that each organ system plays in each activity, as well as explain how organ systems work together to perform the chosen activities.
Examples of activities students might choose:
• Arts (drawing/painting, dance or music performance, acting)
• Athletics (exercises/workout routines, sports)
• Food/Culinary-related (cooking, eating different cuisines)
• Other hobbies (video games/TV)
• Other student choices?
Connections with your chosen activities may be:
• Direct – How are your chosen activities directly controlled/performed by different organ systems and processes in the body?
• Analogies – How are your chosen activities similar/analogous to different organ systems and processes in the body?
Answer:
When you breath, your lungs expand filling the blood with oxygen, when you eat, the food breaks down in your stomach causing the nutrients from the food to be absorbed by your body/blood, when you play sports or exercise that newly oxygenated/nutritionized blood is then pumped faster through the body by the heart.

Why do organisms that fertilise internally tend to produce less eggs?
Answer:
Explanation: Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.
Choose all the answers that apply. The atmosphere: is mostly made of nitrogen is weightless protects earth from harmful radiation contains water vapor is affected by events in the hydrosphere
Answer:
The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.
Explanation:
The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.
The Earth´s atmosphere is composed of water vapor, N₂ (78.08%), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. Water vapor might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. They protect the Earth from harmful radiation.
The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.
Answer:
is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor

Healthy ecosystems depend on–
Healthy ecosystems depend on a variety of factors working together in balance.
Some key factors include:
1. Biodiversity: Healthy ecosystems have a rich variety of species, including plants, animals, and microorganisms.
2. Nutrient Cycling: Ecosystems rely on the cycling of nutrients, such as carbon, nitrogen, and phosphorus, to support the growth and survival of organisms.
3. Energy Flow: Ecosystems depend on the flow of energy from the sun. Producers, such as plants and algae, convert solar energy into chemical energy through photosynthesis.
4. Interactions and Relationships: Healthy ecosystems are characterized by complex interactions and relationships among organisms.

A scientist observes a geyser erupting. Which two objects must be interacting beneath the surface?
O well and spring
O spring and magma
O magma and groundwater
O groundwater and unsaturated zone
Answer:
c
Explanation:
Magma and groundwater are responsible for the eruption of geyser.
GeyserGeyser eruptions are as a result of the conversion of thermal to kinetic energy during decompression.
When the groundwater deep in the ground is heated up by magma, pressure is released and the water will erupt out of the ground as a geyser. Eruptions occur about every 50-100 minutes.

Comparing structures of embryos is an example of __________________.
If embryos share a common structure, what does that say about their evolutionary relationship?
How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.
Answers:
1.blank: Homologous
why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.
2.blank: Analogous
why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.
3.blank: Homologous
why?: (see question 1 ^)
4.blank: Vestigial
example: An example of a vestigial structure is a human's tail bone.
why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.
5.blank: Embryology
why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.
6.answer: They share a common ancestor
why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.
7.answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.
why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.

An animal's color could help it survive by blending into its surroundings so it is less visible to predators and prey.
Example: A polar bear's fur is white, and all the snow in Antartica is also white. Therfeore, it is hard for predators to find the polar bear and for prey to escape because they don't see the polar bear.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.
Answer:
Both creates new cells
Explanation:
Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.
What is meiosis?Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.
In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.
Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.
