Answer:

The rift valley formed when the crust pulled apart.

Explanation:

The statement that best describes how the Great Rift Valley in Africa formed is that they formed when the crust pulled apart.

This is geologically known as divergence.
The Arabian plate and the Nubian/Somali plate are divergent plates.
They are currently moving apart and away from each other.
This creates a crack on the earth which is what formed the rift valley in Africa.
Along such margins, earthquake activities are prominent.

Answer/Explanation:

You would have to be very careful of cross-contamination. That means you would have to work very carefully and precisely with protective clothing, ensuring that none of your DNA (from skin or hair or even trace) gets into the sample you are working with
You would have to be very careful to check and record samples properly to ensure nothing got mixed up or mislabeled and this could be disastrous for criminal cases
All the material is very precious and sometimes only one sample exists, so you have to avoid making any mistakes. Experiments can't always be repeated.

Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or w

nlexa [21]

Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.

Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.

Weak contraction

Potassium accumulates in the sarcoplasm.
Contracted lower sarcoplasm pH.
Begin contraction with muscle already 50%.
The circular arrangement of muscle fascicles.

Stronger contraction

Increase in muscle belly circumference.
A lesser proportion of motor neurons to muscle fibers.
Increased recruitment.
Increased stimulus frequency.

Answer:

According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).

Explanation:

The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.

The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.

The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.

The other options are not correct because:

C and D. In developing countries such as Nigeria and Ethiopia, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape.

B. Italy, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.
