Answer:
C
Explanation:
What evidence did Darwin use to support his theory of evolution? Select three options.
1. in-depth studies of individual organisms
2. observations of fossils
3. finches on different islands had different types of beaks
4. young finches that acquired desirable traits as they aged
5. observations of different species with varying traits
Answer:
2, 3, 5
Explanation:
Darwin's theory of evolution is most often associated with his study of finches.
He noticed that finches present on different islands had different types of beak suited to that particular environment. On one island, the beaks were better suited for cracking nuts. On another, they were long and thin for searching for bugs.
These finches came from a common ancestor, and migrated to different islands. Due to natural selection and lack of intermixing between the islands, the finches developed different traits over time.
He did this work with other species as well, noting that different species had developed distinct features that suited them to their environment.
Darwin also studied fossils, which provided evidence that animal form (anf function) changed over the course of thousands of years. This supported his idea of evolution that resulted from natural selection.

The following image is of a diatom. It lives in water and gets food from photosynthesis. It is encased in a hard shell made of something similar to glass or sand.
Image by Damián H. Zanette
A diatom is a(n) _______ because it has _______.
Answer:
A diatom is a(n) autotrophic algae because it has chlorophyll.
Explanation:
Diatom is a type of unicellular and eukaryotic algae which has the ability to make their own food like plants from sunlight due to the presence of chlorophyll pigment. Diatom helps in fixation of carbon in the process of photosynthesis. About 20 percent of carbon fixes by diatom and plays an important role in climate change. It lives in water and provides food for many herbivores.

An incident in Donora, Pennsylvania, led to which action?
banning the burning of coal
enacting air pollution laws
banning the use of CFCs
conducting cost-benefit analyses
Final answer:
The incident in Donora, Pennsylvania led to the enacting of air pollution laws, including the passage of the Clean Air Act in 1954. This event significantly influenced environmental regulations, setting emission limits and advancing command-and-control policies to reduce industrial pollution.
Explanation:
The incident in Donora, Pennsylvania had a profound impact on environmental regulation in the United States. In 1948, Donora was the site of one of the worst air pollution disasters in the nation's history, when a combination of a temperature inversion, local industrial pollution, and the burning of soft coal resulted in a thick smog that persisted for five days. As a result of the Donora Smog, which caused severe health issues and deaths among the local population, enacting air pollution laws became a priority.
A significant outcome of this event was the passage of the first Clean Air Act in 1954, a key piece of legislation that was further strengthened in subsequent years. This act led to regulations that directed industries to reduce emissions, and it pioneered the approach of setting limits on pollutants, leading to the improvement of air quality and the reduction of negative health effects.
These air pollution laws are a form of 'command-and-control regulation', wherein governments specify allowable limits of emissions and require the installation of pollution-control technologies in factories, power plants, and on vehicle tailpipes. By enforcing these regulations, firms have to account for the social costs of pollution, representing a move towards the internalization of environmental externalities into the production process.
The Arctic cod is a small forage fish that is a very important part of the food web. It eats mostly zooplankton and lives water between -2 and 0°C due to a type of antifreeze in its blood. How does a warming climate and seas waters as well as ice melt impact the Arctic cod and the other organisms in the food web?
A) As the water temperatures warm, the plankton increases, the cod increases and all of the higher level consumers also increase.
B) As ice melts and temperatures increase, the polar bears decline so all other animal populations, including the Arctic cod, increase.
C) The Arctic cod lives in a very small temperature range. If it begins to die out, the food source for the next level of consumers will be reduced.
D) The Arctic cod will eventually adapt to the changing water temperatures. Since there is plenty of food for the cod, its population should remain stable.
Answer:
The answer should be C.

What will likely happen to the population of these beetles during the next year if the resource level stays the same?
Explain your answer.
The population of beetle will stay the same if the resource stay constant do not show any effect on the population.
What do you mean by population of a species ?A population is nothing but a cluster of individuals of the same species reside in a same geographic location and interbreed with each other.
Age structure, sex ratio, the rates of reproduction and death are some demographic structure of a population.
The demographic structure of a population is needed to understand the cause of increase or decrease of a population over time, the changes in species with respect to their environmental and how the trait of a species evolve.
For the determination of ecological dynamics of populations resource availability is one determinant, where fluctuations in resource availability can either increase or decrease the intensity of competition for resource which lead to an evolutionary changes in traits.

Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?
1) 0%
2) 25%
3) 50%
4) 100%
Answer:
Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?
RR x rr= Rr, Rr, Rr, and Rr
Red x White= Pink heterozygous
Rr x rr= Rr, Rr, rr, and rr
Pink x White= 0% as both Pink and white shares it with 2:2 or 50:50%
Explanation:
Final answer:
When pink flowers (incomplete dominance, CRCW) are crossed with white flowers (CWCW), the resulting phenotypic ratio is 1 pink (CRCW) to 1 white (CWCW). No red flowers (CRCR) will be produced, so the expected percentage of red flowers is 1) 0%.
Explanation:
The question is asking about the expected phenotypic outcome when you cross pink flowers with white flowers in a case of incomplete dominance. In incomplete dominance, a heterozygous organism (with one dominant and one recessive allele) shows a phenotype that is intermediate between the homozygous dominant and homozygous recessive phenotypes.
For example, in snapdragons, red flowers (CRCR) crossed with white flowers (CWCW) yield pink flowers (CRCW), where pink is the heterozygous condition. If pink flowers (CRCW) are crossed with white flowers (CWCW), the Punnett square combination will give us CRCW (pink) and CWCW (white) offspring. No CRCR (red) offspring will be produced because the white parent can only pass on the CW allele. So, the correct answer for the expected percentage of red flowers is 0%.
The genotypic ratio from this cross is 1 CRCW:1 CWCW, leading to a phenotypic ratio of 1 pink:1 white. No red flowers would be produced in this cross.

Which do you think has a stronger influence on a plant - gravity or light?
How could you design a new experiment to test this?
Influence of plant under gravity or light is described below.
Explanation:
Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism. ... As a result, root cells on the upper side of the root grow longer, turning the roots downward into soil and away from the light. Roots also will change direction when they encounter a dense object, such as a rock.Geotropism (also called gravitropism) is the directional growth of an organism in response to gravity. Roots display positive geotropism when they grow downward, while shoots display negative geotropism when they grow upward. ... These cells contain small bodies that sink to the bottom of the cells in response to gravity.Tropisms are growth-mediated plant movements that help plants to respond to changes in environmental stimuli. ... The plant response to gravity (gravitropism) and the response to unidirectional light (phototropism) have long been shown to be interconnected growth phenomena.Final answer:
An experiment to discern whether gravity or light has a stronger influence on plants could involve observing plant growth under varying conditions of light and simulated gravity, employing methods such as clinostats for gravity and directional light sources.
Explanation:
The question about whether gravity or light has a stronger influence on a plant is rooted in the field of Biology. The phenomena of gravitropism and the effects of red and blue light on plant growth and metabolic activities are pivotal to understanding these influences. Gravitropism is the growth response of a plant in relation to the force of gravity, with roots showing positive gravitropism by growing downwards and shoots showing negative gravitropism by growing upwards.
Designing an Experiment:
To test the stronger influence between gravity and light on a plant, you could design an experiment where plants are grown in two sets of conditions - one where light direction varies and gravity is constant, and another where gravity varies and light direction is constant. This could involve using a controlled environment with artificial light and a rotating space to simulate changes in gravity. Observing growth patterns, direction, and general health of the plants in these varied conditions would offer insights into which factor has a stronger influence.
For instance, by rotating plants on a clinostat to simulate microgravity and using directional light sources, we can observe differences in growth direction and vigor as each variable changes. This comparative study would contribute valuable insights into plant responses.

Mimicry is an resemblance between an organism and another object and they
advantages are???
Answer: Camouflage or deterring predators
Explanation: Mimicry can help an organism blend into its surroundings if they are resembling something in the environment.
It can also help deter predators if they are resembling a poisonous or venomous organism; an example of this is the non-venomous king snake, which mimics the venomous coral snake to deter predators from eating it.
Answer:
1). Its advantages is defense adaption.
2). It makes them look like an uninteresting object.
3). It becomes a specie that potential predators normally avoid because it posses an unpleasant or harmful feature like a foul smell or taste, or a poisonous sting.
Note: Several insects look like dead leaves and bird droppings and so, although noticed, are ignored by their potential predators. Example is in Mullerian mimics, unrelated animals like the striped polecat and the striped weasel of the savanna have similar broad white stripes on a black body. Their enemies associate the conspicuous appearance with the foul smelling liquid they squirt, and so avoid them.
