Which characteristics are typical of a human population in the pre-industrial stage?
A - Exponential total population growth
B - High and stable total population size
C - Sharply dropping birthrate and death rate
D - High birthrate and death rate
(Apex) Please Help !!!
Answers
Population growth is defined as the increase in the number of people in a population. The population growth in the preindustrial age was very slow and constrained to food resources.
The characteristic typical of the human population in the given graph is the high birth and death rate.
The preindustrial era had high birth rates and death rates because the work in the agricultural field requires larger families and labor. These societies also had limited knowledge of birth control.
The death rates are higher because of poor living standards and constrained available food resources.
Birth rates are the total number of births per 1000 population, whereas the death rate is the number of deaths per 1000 population in a year.
Thus, the correct answer is Option D.

https://brainly.com/question/12228859
In the pre-industrial stage (Stage 1), typical characteristics of a human population include high birthrate and death rate, leading to stable population growth.
Explanation:The characteristics that are typical of a human population in the pre-industrial stage, which is also known as Stage 1 of the demographic transition model, include high birthrates and high death rates. This stage is characterized by a largely agricultural society, with families often larger due to a high infant mortality rate and a need for labor. The life expectancy is relatively short, healthcare is minimal or non-existent, and the population growth is stable because the high number of births is balanced by a similarly high number of deaths.
In summary, the correct answer to the question is D - High birthrate and death rate.

How does introduced species harm our planet?
Please someone answer this
ASAP!!!
Answers
Introduced species can harm our planet because in some regions of the world we are not prepared for their type of species, which can all in all cause damage.
Answer: alteration of the ecosystem
Explanation:when a new specie is introduced into the ecosystem it may have profound affects in the ecosystem and may also be called an invasive specie.
The affects that it may have on the ecosystem include
1.outcompeting the native specie and sometimes even leading to their extinction because the new specie may be modified in such a way as to have better chances of survival in the ecosystem because of their evolved genetics e.g : the new specie may encounter a native and non evolved specie of the ecosystem and compete with it for survival leading to reduction and even complete eradication of the native specie
The four principles of natural selection
Answers
1) Variation: there needs to be a difference in the individuals within a population
2) Inheritance: These variable traits must be able to be passed down genetically
3) Growth rate: There needs to be a growth rate that requires a struggle for resources
4) Survival rate: There needs to be a difference in survival rate for the different variation types... certain variations will live
The four principles of natural selection are variation, inheritance, high rate of population growth, and differential survival and reproduction. This means members of a species are variable, part of this variation is inheritable, populations produce more offspring than can survive, and those with better survival traits are more likely to pass them on.
Explanation:The four principles of natural selection are: variation, inheritance, high rate of population growth, and differential survival and reproduction.
The principal of variation means individuals within species are variable. Inheritance means that some of these variations are passed on to offspring. High rate of population growth means that populations produce more offspring than can survive, leading to competition. Lastly, differential survival and reproduction states that individuals with advantageous traits are more likely survive and reproduce than those without these traits.
Combined, these principles drive the process of natural selection, causing species to adapt to their environments over time. In any given environment, the individuals with traits best suited to that environment will have the greatest chances of surviving and passing those traits on to the next generation.

A geologist concludes that a rock sample is an extrusive igneous rock. Based on this information, which statement about the rock is accurate?
A. The rock formed from cooling lava.
B. The rock likely came from a pluton.
C. The rock cooled slowly over millions of years.
D. The rock formed within Earth's crust.
Answers
The correct answer is D
The accurate statement about an extrusive igneous rock is that it formed from cooling lava, which cools quickly at the Earth's surface, leading to a finer-grained texture.
Based on the information that a geologist concludes a rock sample is an extrusive igneous rock, the accurate statement about the rock is A. The rock formed from cooling lava. Extrusive igneous rocks such as basalt are formed above the surface when molten rock, known as lava, extrudes onto the Earth's surface and cools quickly. This rapid cooling does not allow large crystals to form, leading to a finer-grained texture, and in some cases, such as with obsidian, a glassy texture due to the extremely rapid cooling.
Option B is incorrect because rocks that come from plutons are intrusive, rather than extrusive, and they cool slowly within the Earth's crust. Option C is incorrect as extrusive igneous rocks do not cool slowly over millions of years. Option D is also incorrect because extrusive igneous rocks form at the Earth's surface, not within the Earth's crust.

Answers
Structure A in Figure 10-4 is the centrioles. role does structure A play in mitosis is: (c) connect to spindle fibers
Centrioles are paired organelles that are found in the cytoplasm of eukaryotic cells. They are composed of microtubules, which are long, thin filaments that form the structural framework of the cell. During interphase, the centrioles are located near the nucleus and are surrounded by a cloud of protein called the centrosome.
As the cell progresses into mitosis, the centrioles replicate and move to opposite poles of the cell. This process is called centrosome separation. The centrosomes act as organizing centers for the spindle fibers, which are microtubules that extend from the centrosomes and attach to the chromosomes. The spindle fibers play a crucial role in separating the chromosomes during mitosis.

The two immediate functions of the eardrum are auditory and protective.
The eardrum is the membrane of the middle year which vibrates in response to sound waves; also the tympanic membrane.
How can we protect(s) the eardrum from dirt?The earwax is the part of the ear that protects the eardrums from dirt and infections. These are produced by glands in the skin linings of the ear canal responsible for protecting the ear. The ear is divided into three sections: Outer, middle, and inner ear.
Earwax is found in the outer ear section lining the ear canal protecting the passage to the eardrum.
Earwax when removed in excessive amounts may cause the ears to develop certain infections and might cause the infections of the other sections of the ears as well.

Solve this Sex-Linked traits practice problem

BB = normal blood clotting
Bb = carrier for hemophilia
bb = hemophiliac
Because the mother does NOT have hemophilia, we will be using BB x Bb to find out the alleles of their children. Because this is sex-linked traits practice, our alleles will be the following.
normal = X^BY
(uppercase B represents no hemophilia)
X^BX^b
Let’s cross them and see what we get!
X^B Y
X^B | X^BX^B X^BY
X^b | X^BX^b X^bY
As you can see, 0/4 of the females (represented by XX) will have hemophilia. Again, it is only present when there are two recessive alleles and none of them satisfy that.
2/4 of the females will be carriers (X^BX^b).
As for the boys, 1/4 will have normal clotting and 1/4 will have hemophilia. None of the males will simply be carriers.
