The pons plays a crucial role in REM sleep, which is the state of sleep in which dreaming occurs. 

The pons is a mass of nerve fibers located at the base of the brain in an area known as the brainstem. It is the largest part of the brainstem and connects the two halves of the cerebellum.

The brain region indicated in the figure is the PONS (Option D).

The pons is located below the midbrain and above the medulla oblongata (i.e., the medulla).

The main functions of the pons include sleeping, waking and dreaming (Option B).

The pons plays a fundamental role during rapid eye movement sleep (REM), which is a unique phase of sleep characterized by the random rapid movement of the eyes.

The pons regulates the functions carried out by the cranial nerves and carries information related to motor function, including walking.

In conclusion, the brain region indicated in the Figure is the pons, whereas the main functions of the pons include sleeping, waking and dreaming.

Most people think babies are equally likely to come as either a boy or a girl. this is not true. actually, about 51.3% of all babies are boys. if a family has two children (not twins), what is the chance they have one boy and one girl? round your answer to two decimal places.

Answers

49.97% For this problem, let's consider the probability of each of the four possibilities for having two children, being BB, BG, GB, and GG. Then sum the probabilities for both the BG and GB events. So BB = 51.3% * 51.3% = 26.3169% BG = 51.3% * 48.7% = 24.9831% GB = 48.7% * 51.3% = 24.9831% GG = 48.7% * 48.7% = 23.7169% If you check, you'll notice that the sum of all the probabilities add up to 100% like it should. And the sum of BG + GB is 24.9831% + 24.9831% = 49.9662% which when rounded to 2 decimal places is 49.97%

A. first, Sun and core of Earth
B. second, Sun and rock
C. second, Sun and biosphere
D. third, core of Earth and hydrosphere

Answers

the correct answer to your question is A, first, sun and core of the earth I hope this helps you out, let me know if its right. Im 100% I am. 

Answer:

Option A, first, Sun and core of Earth

Explanation:

According to first law of thermodynamics,  

An energy can never be created nor destroyed, it can only be converted from one form to other and therefore the first law of thermodynamics is known as law of conservation of energy.  

There are only few energy sources for planet earth – Solar energy, gravity, rotation of earth and radioactive energy

Solar energy is the prominent source of energy that drives several natural process like winds, hydrologic cycle, biosphere ecological cycle , and also derives the overall climate system . While the earth core causes gravitational force which is very essential for several natural process like rotation, tides, etc.

Major factors that determine a population's growth rate

Answers

The main factor that determines a populations growth rate is the availability of resources. Other factors can contribute, such as competition for food, disease, weather, immigration/emigration, birth/death rate, etc.

Final answer:

The population growth rate is influenced by birth rates, death rates, immigration, and emigration. The equation to calculate growth rate is growth rate = birth rate – death rate. Economic growth is also related to population growth, as labor demands affect GDP and standards of living.

Explanation:

Major Factors Determining Population Growth Rate

The growth rate of a population is primarily determined by four key factors: birth rates, death rates, immigration, and emigration. If the birth rate exceeds the death rate, the population increases. Conversely, if the death rate is higher than the birth rate, the population size will start to decline. When birth and death rates are equal, the population size remains constant. Additionally, populations gain individuals through immigration and lose individuals through emigration.

Furthermore, population growth can be calculated using a simple formula: growth rate = birth rate – death rate. This equation highlights the importance of fertility rates, life expectancy, and net immigration levels, which are also considered by demographers when studying population characteristics. Populations do not always grow continually; growth depends on various factors, including the average age of individuals within the population, local economic conditions, and availability of resources such as food, moisture, and oxygen.

When discussing population growth and economic growth, the labor market and population size are crucial since they influence the Gross Domestic Product (GDP) and, consequently, the standard of living. As the economy grows, more labor or increased labor productivity is necessary to meet consumer demands. Countries with smaller, well-managed populations often enjoy higher standards of living than overpopulated ones. Thus, population growth rates have a direct impact on economies locally and globally.

For the I+P+OcZ−Y+ genotype, In terms of regulation, functional repressor (I+) is made, however the operator region is mutated (Oc).

list the organelles found in plant cells, in amoeba, and common to both.

Answers

cytoplasm, ribosomes , nucleus
tonoplast, mitrotubule , nuclear pores

Answer:

Amoeba are unicellular eukaryotes found in aquatic environments. The organelle that is found in amoeba are nucleus, contractile vacuole and food vacuole and organelle found in plant cells are nucleus, endoplasmic reticulum, Golgi apparatus, vacuole, chloroplast, mitochondria, peroxisomes.

The organelles that are common in amoeba and plant cells are nucleus and vacuole. Both plant and amoeba have a membrane-bound nucleus in which their genetic material is packed.

The role of the vacuole in plant cell and amoeba is that it maintains the proper osmotic pressure in the cell and prevent cell from bursting. It also helps in the collection of waste material and its disposal.

Which time period saw the loss of 96% of all marine species and 70% of all terrestrial species?

Answer:

Permian-Triassic mass extinction

Explanation:

The Permian-Triassic  extinction event, occurred at about 252 MYA. This period marks the boundary between the Permian and Triassic  periods. It is the most severe extinction event that took place on earth, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct. Due to such a great biodiversity loss, the recovery of life on Earth took a longer time than other extinction events.

How many moles of O2 are required for the complete reaction of 88.9 g of C2H4 to form CO2 and H2O?

Answers

The molecular mass for C2H4 should be: 2*12 + 4*1= 28 gram/mol. Then the amount of mol in 88.9 grams C2H4 should be: 88.9g/ (28g/mol)= 3.175 mol.

To answer this question, you need to know the reaction formula for the problem. The formula should be: 
C2H4 + 3O2 --> 2CO2 + 2H2O 
In the formula, every 1 C2H4 will be reacted with 3 O2. Then the amount of oxygen needed would be: 3/1 * 3.175 mol= 9.525 mol
