C) Rule 2 - All contour lines eventually connect with themselves.
D) Rule 1 - All points along the same contour line are at the same elevation.
Drawing A violates this rule because the contour lines cross each other, which would imply that the same point is at two different elevations. Drawing B violates this rule because the contour lines split and branch, which would imply that a single point is at multiple elevations.
Drawing C violates this rule because the contour lines do not follow the same elevation, with some areas being higher and others being lower. Drawing D violates this rule because the contour lines do not connect with themselves and appear to be cut off, which would imply that the area beyond the drawing has a different elevation.

Answer:
This question lacks options: 1) keystone species. 2) symbiotic species. 3) sympatric species. 4) allopatric species. 5) refugistic species. The correct answer is 1) keystone species.
Explanation:
Keystone species are the species that have a more important effect on the ecosystem than expected for its low biomass, exerting a direct influence on the others, that is, a key species can have different effects on its ecosystem or on other species with those that cohabit. Among them are: Modification of the landscape, source of food, generators of shelter, altering ecological processes. This makes their presence very meaningful.
Terat and Linan went to the zoo with their grandparents and saw two tigers in side-by-side exhibits. One tiger was white with stripes, and the other was orange with stripes. Terat noticed the signs on the exhibits both said "Bengal Tiger" and wondered why they were different colors if they were the same type of tiger. They read the rest of the sign in front of the white tiger exhibit. The sign explained that there was a relationship between the composition of the proteins in each tiger's genes and the different colors expressed in their coats. They learned the change in protein composition was because of
A. Species evolution
B. Genetic mutation
C. Sunlight exposure
D. Habitat adaptation
Answer: Option B. Genetic Mutation
Explanation: White tigers are Bengal tigers that have two copies of a very rare recessive gene that controls coat color. Specifically, researchers have discovered that white tigers are caused by a single gene mutation in the protein known as SLC45A2.

Why is it an advantage for plants in the shade to have leaves with a large surface area?
Answer:
The larger shade leaves provide a larger area for absorbing light energy for photosynthesis in a place where light levels are low. In contrast, smaller sun leaves will provide less surface area for the loss of water through transpiration. ... Shoots grow more quickly in height where light levels are low.
Explanation:
Mark as brainliest
Plants in the shade benefit from having leaves with a large surface area because it allows them to capture as much light as possible in low light conditions.
In shady environments, the availability of sunlight is limited, and plants need to maximize their light absorption to support photosynthesis, which is crucial for their growth and survival.
By having large leaves, plants can increase their surface area exposed to light, enhancing their ability to capture and utilize the limited available light energy.
This adaptation enables shade-dwelling plants to optimize their photosynthetic processes and obtain the necessary energy for vital metabolic activities, despite the reduced light intensity in their environment.

What distinguishes science from other disciplines that do not use scientific methods?
O Science relies on observation, measurement, and experimentation.
O Science relies on fixed experimental results that cannot be changed over time.
O Science can answer all questions about the natural world through experimentation
O Science relies on anecdotal evidence that may or may not be measured and verified.
Answer:
Science relies on observation, measurement, and experimentation.
Explanation:
If science is not understood exclusively as a system of knowledge, but also as
a kind of human activity aimed at acquiring new knowledge about reality - the question of the method by which such activity is performed arises.
In order to be properly defined, science must point to the method it uses and its features - criticality.

Which of the following are benefits of genetic diversity? Select all that apply.
1 gametes are identical as a result of meiosis
2 species survive despite negative mutations
3 offspring are identical to parents
4 species adapt to ever-changing environments
5 gene pool is strengthened
Answer:
The benefits of genetic diversity include:
2- species survive despite negative mutations 4- species adapt to ever-changing environments 5-gene pool is strengthenedExplanation:
Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.
Several alleles within a population's gene pools leads to higher diversity. These may become beneficial, as the environment of the organism changes.
Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.

having explanations that answer all questions
Answer:
im pretty sure its 1 2 3 and 5
Explanation:
cause pseudoscience is based off nothing but feelings and opinion
The main differentiation is using models and experiments, asking new questions, having explanations that answer all questions. The correct options are B, C, and E.
What is pseudoscience?Pseudoscience is a proposition, a finding, or an explanation system that is presented as science but lacks the rigor required by the scientific method.
Pseudoscience can also result from research that is based on flawed premises, a flawed experimental design, or poor data.
Astrology has not been proven effective in controlled studies, has no scientific validity, and is thus considered pseudoscience.
The main distinction Popper draws between science and pseudo-science is one of attitude.
A pseudo-science is set up to look for evidence that supports its claims, whereas a science is set up to challenge its claims and look for evidence that may prove it false, according to Popper.
Thus, B, C, and E are correct options.
