Oksanka [162]

Answer:

Cephalocaudal

Explanation:

The cephalocaudal principle is known as the general process of physical and motoric development which take place from infancy into toddlerhood and at times at early childhood of which development obeys a head-to-toe progression.

Cephalocaudal is a word that connotes head to toe. Therefore, the cephalocaudal principle is stated as the overall process of development observed in the first set of years in postnatal development majorly with the period from infancy into toddlerhood.

The cephalocaudal principle has to do with both physical and functional development. On the basis of the earliest (i.e., physical development), physical growth in size, weight, and feature differentiation obey this process or form of development. The signs of this is well observed in a contrast of the physical characteristics of an infant In contrast to a toddler. In consideration of the latter, the head is mostly disproportionately big in contrast to the other parts of the body. By the time the preschool years is over for most children, it is well noticed that most must have done away with this top heavy appearance just as seen in our question.

HAPPY NEW YEARS !!! CAN SOMEONE PLEASEEEE HELP ME WITH THIS SCIENCE QUESTION I WILL MARK YOU BRAINLIEST !!!

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.

Stels [109]

Answer: alternative A

Explanation: The deeper the layer in water, the less light reaches it. In deeper layers, therefore, it becomes difficult, if not impossible, to photosynthesis to occur. Having in mind that phytoplankton and photosynthetic organisms depend on photosynthesis to survive, they won't appear in such dephts.
