What changes an object's speed and direction? *
A. Friction
B. Acceleration
C. Gravity
D. Inertia
Answer:
C
Explanation:
A change in speed is a change in velocity – so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. Force – a push or pull When a force acts on an object; it may change the object’s acceleration (speed, direction, or both).
The chart shows the total amount of nitrogen oxides (NOx) and sulfur dioxide (SO2) that coal-fired utilities emitted between 1999 and 2013. Based on the chart, do you think the steps taken by the EPA and the factories were effective in reducing air pollution from these two pollutants? Give your reasons.
Answer:
Yes.
Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
Answer:
Yes, the steps taken by the EPA and factories were effective in reducing air pollution from NOx and SO2 because the emissions of these two pollutants have decreased over the years.

When do mountains get built?
Answer:
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.

How does the cell cycle ensure an organism’s survival?
Options:
I. It helps organisms grow and develop
II. It helps all organisms repair tissues
III. It helps all organisms reproduce
I. and II. only
Answer:
Cell growth and development include its repair. As cells grow old, they wear off. Sometimes they suffer injury and bruises, but they are able to repair themselves by growing new cells in a process called Mitosis. As living things grow, they undergo a process called aging (age

What kind of adaptations could have given homosapiens an evolutionary advantage over neanderthals and other species of humans?
Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.

Answer:Natural selection works to change populations by favoring some variations in individuals and working to eliminate other variations in individuals. Natural selection is basically a culling process.Apr 2, 2018
Explanation:
The branch of science which deals with genes and inheritance is called genetics.
The correct answer is C.
Adapting in an environment changes in order to survive in a system is called natural selection. The key factor for natural selection is the variation that leads to the change in the genotype of the population.
According to the question, the correct answer is C because the changed and evolved traits must be transferred to the next generation to have better chances of surviving.
Hence, the correct answer is C. The likelihood that traits of organisms are passed on

Salivary amylase is an enzyme in humans that breaks down starches. What substances would humans have difficulty digesting without this enzyme
Group of answer choices
Answer:
Carbohydrates
Explanation:
High in fats and very fatty
In the absence of salivary amylase, humans would have difficulty digesting carbohydrates.
What is salivary amylase?Salivary amylase is produced by the salivary glands located towards the back of our mouth. Salivary amylase is a very small percentage of the total amount of amylase produced by the body.
Most of the amylase in the body is secreted by the pancreas. Salivary amylase is secreted in the saliva. This begins the process of the breakdown of food in the mouth itself.
Salivary amylase breaks down carbohydrates into maltose units which is a disaccharide. The maltose is ultimately broken down into glucose.
Carbohydrates are a very significant portion of the diet of a large percentage of the global population. Various kinds of bread and rice have a large portion of them composed of carbohydrates.
Therefore, in an absence of salivary amylase, humans would have difficulty digesting carbohydrates.
