Give 4 ""combining evidence"" in favor of organic evolution.
Answer:
1. Fossil record
2. Comparative anatomy
3. Embryology
4. Biogeography
Explanation:
Evolution is descent with modification. The organic evolution theory states that present complex life forms have evolved from the earlier (simpler) forms of life over time. Some of the most important pieces of evidence in support of the theory of organic evolution are:
1. Fossil record: fossils are dead remains of past living organisms preserved in the rocks of the remote past. These fossils demonstrate the existence of past living organisms that are related to present-day organisms.
2. Comparative anatomy refers to the study of similarities in the anatomy of different species, which provides direct evidence for identifying common ancestry between related species.
3. Embryology: the more recent the ancestor is that two species share, the greatest similarities in embryo structures and the more closely related the species are. In this regard, it is important to highlight that often homologous organs/structures (i.e., organs/structures descended from a common ancestor) can be observed only in embryos.
4. Biogeography refers to the spatial distribution of organisms and species. Species distribution reflects the evolutionary process when it is combined with geological change. For example, taxa that had already appeared before the separation of the continents are often distributed worldwide.

2. Energy flows through Earth's spheres and changes along the way. Describe how energy is conserved in these systems. (2 points)
Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.

Compare and contrast a fossil and a trilobite.(1 point)
A (Both fossils and trilobites are relativity new, both being around 1,000 years old. However, fossils are only found under water, whereas trilobites are found all over the globe.
B (Both fossils and trilobites are relativity new, both being around 1,000 years old. However, trilobites are only found on the bottom of the ocean, whereas fossils are found only on land.
C (Both fossils and trilobites are extremely old. However, a fossil was a creature that was living on Earth at some point that over time turned into a trilobite, meaning a fossil is one type of many different types of creatures found in trilobites.
D (Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils.

Answer:
D. Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils.
Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils. So, the correct option is D.
What do you mean by Fossil?Fossils are the preserved remains of the organisms whose bodies were buried in the sediments, such as sedimentary rocks.
Trilobite is a member of a group of extinct fossil arthropods easily recognized by their distinctive three-lobed and three-segment forms. It is exclusively a marine animal. It first appeared at the beginning of the Cambrian period.
Therefore, option (d) significantly compares and contrasts a fossil and a trilobite.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.
