How did Watson and Crick learn about Chargoff's rules?
Answer:
Chargaff explained his findings and research to Watson and Crick at Cambridge.
Explanation:
Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.
Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

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.

using models and experiments
asking new questions
making subjective claims
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.

Match each type of stress with its description.
stress caused by rocks pulling apart
compression
stress caused by rocks being pushed in
opposite directions
tension
stress caused by rocks pushing together
shearing
Correct!
Answer:Shearing: stress caused by rocks being pushed in opposite direction
Tension: street caused by rocks pulling apart
Compression: stress caused by rocks pushing together
Explanation:
Matching the description with each type of stress associated with rocks, we have:
1. Tension: street caused by rocks pulling apart.
2. Shearing: stress caused by rocks being pushed in opposite direction.
3. Compression: stress caused by rocks pushing together.
A rock can be defined as a solid naturally occurring landform that is made up of minerals.
In Geology, stress can be defined as a force that acts on a rock per unit area.
Generally, there are four (4) main types of of stress associated with rocks and these include:
1. Tension: it is a stress typically caused by rocks pulling apart, which makes them to either increase in length or break apart.
2. Shearing: it is a stress typically caused by rocks being pushed in opposite direction due to the effect of parallel forces.
3. Compression: this is a stress that is caused by rocks pushing together, which makes them to either fold or fracture (break).
4. Confining stress: it is a stress typically caused by rocks being pushed down by the weight of any material above it.

In the energy pyramid, the snake is classified as a
A)
consumer
B)
decomposer
herbivore.
D)
producer.
In the energy pyramid, the snake is a consumer. Therefore, the correct statement is option A.
What is a food chain?A food chain is a series of organisms in an ecosystem where the energy flows from one organism to another organism and each organism serves as food to another organism. For example, plant is consumed by herbivore. The herbivore is then consumed by a secondary consumer, which is in turn consumed by a tertiary consumer.
In an energy pyramid provided, the snake is classified as a consumer. Consumers are organisms that consumes other organisms to obtain energy. Snakes are carnivorous animals that consume other animals, such as rodents, birds, etc. Therefore, they are consumers in the energy pyramid.
Decomposers are organisms that feed on dead organic matter, while herbivores are animals that consume only plants, and producers make their own food.
Therefore, snake is a consumer in the energy pyramid.

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.

Explanation:
Predators usually prey upon sick animals so that the best among the specie is able to reproduce and produce the most fertile offspring. This maintains the cycle of nature. If too many predators are killed, it will cause sick animals to live longer. As a result, they will reproduce and the offspring will not be healthy enough which in future, can cause many problems.
