Which of the following best describes evidence from comparative embryology regarding embryos of different species that supports the theory of evolution?
They carry out similar metabolic processes.
They develop in similar environments.
They have the same genome.
They share similar development patterns.
Answer: D.
Explanation: Thus, Comparative Embryology provides strong support for the hypothesis that Darwin put forth to explain the apparent similarities and differences he saw among different species, i.e. that these species are the result of an evolutionary process involving selection (now known to be gene based) for structural and In the mid-1800s, Charles Darwin and Alfred Wallace independently concluded that inherited variations in traits, such as a bird's beak shape, may provide better odds of survival in a given niche. Organisms without the advantageous variation are less likely to survive and pass on their genes.
Answer:
they share similar development patterns

Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

Which of the following contributes most to promoting sustainability in an ecosystem?
A. Lack of decomposers
B. A balanced water table
C. Variety of organisms
D. A narrow temperature range
Answer:A
Explanation:
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.
What is an ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems.
Based on their overall environments, ecosystems can be divided into three basic categories: freshwater, marine, and terrestrial. Individual ecosystem types based on the environmental habitat and creatures present can be found within these three categories.
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.

(8.9B) A student made a chart to classify plates by the types of boundaries. What crustal
feature is most likely found between the South American and African plates? *
A Folded mountain
B Ocean trench
C Mid-ocean ridge
D Fault
Answer:
folded mountain
hope it will help you
The crustal feature is most likely found between the South American and African plates is folded mountain. The correct option is A.
What is folded mountain?When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges at these interacting, compressing limits. Orogeny, a process, is what produces fold mountains.
While having a narrower width than their length, fold mountains are very long.
Concave and convex slopes are typically present on opposite sides of fold mountains. Most fold mountains are located on the edges of continents that face the ocean.
A student created a chart to categorize plates according to the different boundary types. The folded mountain is most likely the crustal feature that lies between the South American and African plates.
Thus, the correct option is A.

How many chromosomes would you expect to be in the daughter cells of the mosquito after meiosis? When starting with 6
Answer:
The correct answer would be - three chromosomes.
Explanation:
Meiosis is the type of cell division that takes place in only sex cells and called reduction division as a single parent cell divide into four daughter cell that contains a half number of chromosomes as the parent cell.
The daughter cells are always haploid and have the half number of chromosomes. If an organism has 2n number of in its parent sex cell the daughter cells after meiosis will have n number of chromosomes
Therefore, mosquito = 2n = 6
after meiosis = n = 6/2 = 3
Thus, the correct answer would be - 3 chromosomes.
Why does darkness affect the light-independent reactions of photosynthesis?
Answer:
Plants stop their daytime activities and rest during the night much like animals do. ... Light independent reactions require the energy gathered in the thylakoids. Mitochondria produce sugars more effectively in the darkness than chloroplasts do.
Explanation:
The diagram below shows a hand warmer. It uses a controlled burn of a type of lighter fluid called naphtha.
The device has a refillable reservoir that holds the naphtha liquid. The fuel moves into a glass fiber burner, which absorbs the fuel and allows it to burn slowly without producing a flame. Oxygen reaches the burner through the holes on the cap at the top of the device. As the fuel is burned, heat is conducted to the metal casing of the device.
When the hand warmer is tested, it becomes too hot and uncomfortable to hold. How could the device be modified to solve this problem?
A.
by increasing the size of the fuel reservoir so that it can store more liquid fuel
B.
by replacing the glass fiber burner with a material that does not soak up liquid fuel
C.
by attaching a covering to reduce the amount of oxygen entering the device
D.
by using a fuel that is more flammable than naphtha so that the fuel can be used faster
Answer:
c
Explanation:
by attaching a covering to reduce the amount of oxygen entering the device
As the territory of Africanized bees continues to expand, what is the most likely outcome?
Answer:
Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.
How do the trachea, bronchi, bronchioles, and alveoli work together to process the oxygen that you inhale?
Answer:
The bronchial tubes divide into smaller air passages called bronchi, and then into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood. After absorbing oxygen, the blood leaves the lungs and is carried to the heart.

What leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions?
A. less biodiversity
B.smaller food webs
C.greater biodiversity
D.specialist consumers
Answer:
C. greater biodiversity
Explanation:
Biodiversity refers to the variation in the kind of species in an area/ecosystem. In other words, biodiversity or biological diversity is how life differs from one another. An increase in biodiversity is of great ecological importance.
One of this importance is that; it leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions. This means, in a nutshell, that it increases the survival chance of species in adverse conditions via the possession of variant traits or characteristics.

Why are food webs more realistic than food chains?
There are more animals
Most organisms eat more than one thing
Most organisms eat each other
Most organisms live on their own
Answer:
The correct answer is -most organisms eat more than one thing.
Explanation:
Food chains are the linear representation of easier visualization of trophic levels or movement of energy through the ecosystem. However, in reality, consumers can depend on more than one producer or other consumers for their food, and energy and interaction among these organisms are not that simple as it shows in the food chain. This makes the food webs to be more realistic than simple food chains.
The food web gives a better idea of the complexity of the various components and movement of energy in an ecosystem because the food webs is are the representation of interaction and interrelation of many different consumers and producers in an ecosystem.
