All animals must be able to take in information and react to their environmental conditions. Describe the organs and organ systems in humans that work together to collect information about the external environment.
Answers
Answer:
Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses. When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.

What are 5 factors that decrease populations (explain each or tell how that factor causes a decrease in a population).
Answers
Answer:
Morality and Emigration
Explanation:
Mortality and emigration decrease the population. Thus, the size of any population is the result of the relationships among these rates. Natality, mortality, immigration, and emigration rates apply to every population, including the human population. The sum of these rates makes up the growth rate of a population.
agricultural changes have been massive over the past 400 years. Many of these agricultural changes even at a low level free up workers from the farms. This allows industrialisation which needs lots of workers and tends to promote high birth rates. The more regular supply of food from advanced farming also promotes birth rates, as people are sure they can feed their children, and reduces famine deaths.
2) Education:
Education plays a vital role in determining the levels of both birth and death rates in a country and hence the level of population growth. As education levels increase people tend to have fewer children so that they can focus their resources in improving the life chances of those few children.
3) Emancipation of women:
In many rich countries women have become over time free to work when they want within their life. This is not the case in all countries in the world where many women are stuck in gender specific unpaid work such as maintaining a household and subsistence farming plots. Women are much more likely now to go to university and work for a few years before having their first child. This can result in fewer children being born per woman as fertility declines with age for women.
4) Urbanization:
It has a significant impact upon population growth because it can impact upon the birth and death rates of a country. As a country becomes increasingly urbanised the birth rate tends to rise and death rates tend to fall.
5) Death rates:
Often death rates are reduced before a slowdown in birth rates, causing a boom in the population size at a certain point in a country’s economic development. Death rates fall and life expectancy increased.

1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answers
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.

Explanation:
In meiosis, Each chromosome will divide to produce two diploid daughter cells, each of which has the same number of chromosomes.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.

Answer:
The correct answer is C. Why do organisms in different places have different traits?
Explanation:
Charles Darwin was a naturalist, biologist, and geologist from England and known for his theory of evolution. According to the theory, he observed different types of species of organisms such as birds, plants and fossils all over the world and found similarities in the characteristics.
He suggested that there were variations in species on the basis of specific geological locations. On the basis of these observations, he proposed that all species of organisms are come from the same ancestor but shows the differences due to the response to the condition of their habitat or location

Answers
Answer:
Presence of inorganic molecules
Explanation:
Earth's primitive atmosphere contained a mix of different inorganic compounds (gases) including, among others, water vapor (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), etc. It has been proposed that these inorganic molecules would generate the conditions needed to form a "primordial soup" of organic molecules (i.e., RNA nucleotides, amino acids, etc). Subsequently, this soup would accumulate in water bodies of the primitive Earth due to endogenous abiotic syntheses and the delivery caused by comet/meteorite collisions.

Is It possible for two parents with a round jaw to have a child with a square jaw? Why or Why not
Answers
Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.
