What percentage of Japan’s population is between the ages of 0–4 years?
Answer:
looks like about 8% to me
40 to 44 percent of people are in the range of 0 to 4 years.
What is the population?A population is a group of different people. There are three different types of population such as rapid growth, slow growth, and negative growth.
In rapid growth, the population will grow rapidly. While slow growth population grows very slowly. In negative growth population growth is negative.
In the population graph, male and female growth is shown. The darker color in the population shows males and the lighter color shows females population.
Therefore, 40 to 44 percent of people are in the range of 0 to 4 years.

The pattern of natural selection where BOTH of the extreme versions of a trait are more advantageous than the average, so a population evolves in both directions away from the average.
Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.

Gene: is a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring. An example is hair or eye color
Allele: is different forms of a gene. An example would be how tall or short.
Homozygous: is two alleles that are the same trait. An example would be two alleles for straight hair.
Heterozygous: is two different traits like one for staright and one for curly hair.
Dominant: is the stronger form of an allele. Like the grey fur is the stronger one
Recessive: is the weaker form of an allele. Like white hair is the least likely.
Pheneotype: is the physical apperance.
Genotype is the genetic makeup of an organism.

BY USING FOREST WISELY;
It was learnt that people are cutting trees at an worrying rate.This problem is disturbing because ;
1)Those trees are responsible for releasing of oxygen and they made up at least a quarter of the world population.
2) Those trees of the world make up of portion land species by more than forth or fifth portion.
There are also economic implications as a result of trees been cut down, when there is no availability bot trees , it could result to situation whereby there would be scarce of resources for industries as well as
hike price of paper in market, regardless of this trees are needed for manufacturing of important materials such as usage in making houses and others developments or growth
Therefore, all the afformentioned economic concern result in economics delay scientists' first attempts.
COMMUNITY CONSERVATION;
It was learnt that there is to the forest that those gorilla habitated, those human being that reside in those region reside there so they can practice their farming because their is available land there. They also reside there because of housing.
These gorillas were affected as a result of the destruction made to their habitat as well as the activities of the poachers that hunt them for production of the and skin.
There are adverse effect of the obliteration of the gorilla from on the society, it can result to having reduction in tourism in country such as
Uganda as well as Rwanda, as result of this the means of livelihood of people in that part could be affected because there would be Reduction in profit making. Hence the reason behind the increase in number gorillas in the region, because they know they know that those gorilla influence the number of tourist that comes there and the revenue that is generated through this tourism.
The article 'By using Forest Wisely' can be summarised as:
People are cutting trees at the wrong rate and trees play a crucial role in an ecosystem. The trees produce oxygen and they made up at least a quarter of the world population.The trees occupy the fourth or fifth portion of the land organisms.In the absence of trees, the ecosystem will fail and the organisms dependent on them will eventually die. The resources available from the trees will be scarce and the factories and industries that are dependent on trees will no longer be available. Trees are required for manufacturing important materials.The article 'Community Conservation' can be summarised as:
In the article, it was mentioned that the human populace urbanized the land region where gorillas were habituating. The humans occupied the space to practice farming and make houses. The population of the gorillas was disturbed and diminished. The hunting of gorillas by poachers was also reduced. The people of Uganda and Rwanda also suffered reduction tourism and conservation of wildlife. Gorillas influence the number of tourists, therefore, the destruction of their habitats led to a reduction in profit-making.Therefore, all the mentioned economic concerns result in economics delaying scientists' first attempts.

Butterflies usually are identified by the colors and patterns on their wings. Butterflies have four wings: The two wings near the butterfly’s head are “forewings” while the wings near the butterfly’s tail are “hindwings.” You can use the following dichotomous key to identify four common butterfly species in North America.
The shown butterfly in the diagram is - Papilio polyxenes.
Butterflies usually are identified by the colors and patterns on their wings. To identify an organism using a dichotomous key, compare the organism’s traits to the first pair of descriptive statements on the key.
Follow the directions after each matching statement until you get to the organism’s identity.The points on the hindwings identify the butterfly as
a swallowtail butterfly is either Papilio glaucus or Papilio polyxenes.1. Hindwings rounded ………………… Goto 3
2. Wings mainly yellow …………… Papilio glaucus
Wings mainly black ………….. Papilio polyxenes
3. Wings orange with black piping…Danaus plexippus
Wings yellow with black edges….. Colias philodice

Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. What would happen to an ecosystem if this process was compromised?
A.
The population of green plants in the ecosystem would increase.
B.
There would be more energy available to consumers in the ecosystem.
C.
The soil quality of the ecosystem would dramatically improve.
D.
The carrying capacity of the ecosystem would be limited.
Answer: D
Explanation:
Since the Earthworms, small insects, and microorganisms live in the soil and break down dead plants and animals. They end up playing a vital role in the ecosystem, if this were to be compromised nothing good would come form it Disease, competition, predator-prey interaction, resource use and the number of populations in an ecosystem all affect carrying capacity. If Earthworms, small insects, and microorganisms couldn't break down the the dead material and return it to the soil, then surely the carrying capacity would be drastically effected.

organization BEST describes an egg?
A. a cell
B. a tissue
C. a system
D. an organ
Answer:
A
Explanation:
Egg cell
The level of structural organization which best describes an egg is: A. a cell.
A cell can be defined as the fundamental (basic) structural, functional, and smallest unit of life, that is typically found in all living organisms such as animals.
The structure of an egg is similar to those of cells found in living organism, which are structurally layered with various cell organelles.
An egg shell is selectively permeable because it acts as an outer membrane just like in living cells to prevent unwanted materials from going into the egg.
In conclusion, the level of structural organization in animals cells can best be describe by using an egg.
