How do muscle cells contract
Answer:
A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.

What do plants use to make up their structure?
Answer:
Molecules of glucose join together to form cellulose. Next, glucose molecules combine to form long chains called cellulose. Cellulose is then used to build plant structures, like cell walls. As more cells divide, the plant's leaves, stems, and roots can grow larger.

Which of the following are narrow blood vessels that restrict blood flow and have thin walls that allow gas exchange?
Answer: Capillaries
Explanation:
The answer choices for this question are Alveoli, Veins, Arteries, Capillaries.
Alveoli are tiny sacs in the lungs that allow for gas exchange.
Veins are blood vessels that carry oxygen-poor blood back to the heart.
Artieries are blood vessels that carry and distribute oxygen-rich blood to the body.
Capillaries are delicate blood vessels that transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system, they have thin walls to allow for gas exchange.
Based on these definitions, the correct answer is capillaries.
Capillaries are narrow blood vessels that restrict blood flow and have thin walls that allow gas exchange.
What are the functions of capillaries?Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
Capillaries connect arterioles and venules and their function is to transfer waste transport to the kidneys and liver and carbon dioxide to the lungs. They are also responsible for the exchange of gases (oxygen) and other substances such as amino acids, sugars, and water.
Continuous nonfenestrated capillaries make up your blood-brain barrier. Here, capillaries control the movement of water, oxygen and other essential substances between your blood and your brain.

The main difference between macroevolution and microevolution is _____.
Select one:
a. the time frame of the evolutionary process
b. the species that evolve during each
c. that microevolution is only for small organisms, and macroevolution is for large organisms
Answer: c. that microevolution is only for small organisms, and macroevolution is for large organisms
Explanation:
Evolution can be defined as the gradual changes that occur in a population of a species or in an individual which supports its survival in the changing environment. Microevolution can be defined as the changes that occur during lifetime in an organism, whereas multiple changes occurring in the organisms over multiple generations. The microevolution is effective over small organisms like insects whereas macroevolution works on large organisms like whale. As the scale of evolution is low in microevolution as small number of changes occur whereas in case of macroevolution the scale of evolution is high so more changes will occur multiple times in an organism.
Answer:
the correct answer is - the species that evolve during each

Which of the following is true of genetic drift?
It can decrease genetic diversity in a population.
It plays a much larger role in determining the genetic makeup of populations than
natural selection.
It is necessary in order for a population to be in Hardy-Weinberg equilibrium.
It can increase genetic diversity in a population.
The statement which is true about Genetic drift is that it can decrease genetic diversity in a population. Thus, the correct option for this question is A.
What is Genetic drift?Genetic drift may be defined as a type of evolutionary force that significantly involves the mechanism of evolution in which the allele frequency of a population may change over generations due to chance or sampling error.
The process of genetic drift occurs in all populations of non-finite size but its effects are strongest in the smallest populations. It is considered an assumption under the Hardy-Weinberg equilibrium. So, option C is eliminated.
The concept of the founder effect and genetic bottleneck always decreases the genetic diversity among the population. So, option D is eliminated.
Therefore, it can decrease genetic diversity in a population is that statement that is true about Genetic drift. Thus, the correct option for this question is A.

You want to determine whether short wings in fruit flies are the result of a dominant or recessive mutation. You cross a short-winged fly stock with a long-winged fly stock (which is considered to be wild type or / ). The progeny have a 1:1 ratio of short to long wings. You then allow the F1 short-winged flies to mate. The F2 progeny have a phenotypic ratio of 3:1 short to long wings. Short wings are likely the result of:
Answer:
a dominant mutation
Explanation:
A monohybrid testcross is a cross-breeding experiment used to determine if an individual exhibiting a dominant phenotype is homo-zygous dominant or heterozygous for a particular phenotypic trait (in this case, wing length). In a monohybrid testcross, a 1:1 phenotypic ratio shows that the dominant parental phenotype was a heterozygote for a single gene that has complete dominance. Moreover, a 3:1 ratio in the F2 is expected of a cross between heterozygous F1 individuals, which means that 75% of individuals with short wings have the dominant allele that masks the expression of the long-wing trait (i.e. the recessive allele).

How do underwater mountain ranges form?
Answer:
They are formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

According to the World Population Growth graph, which best describes the human population growth after the Industrial Revolution?
Slow growth
Exponential growth
Negative growth
Zero growth
Answer:
negative
Explanation:
According to the World Population Growth graph, the human population growth after the Industrial revolution will be exponential growth. Thus, the correct option will be B.
What is the Exponential growth?Population growth can be defined as the annual increase in the population size of a species. Population growth is the difference between the total births less the total deaths and the difference between immigrants less the emigrants, in a given country, territory or a geographic area at a given year.
Exponential growth of a population is a function which shows an increase within a population that occurs at the same rate throughout the time period. When different populations experience doubling or tripling in numbers, then we can assume the data increases exponentially through the time. The opposite of exponential growth is exponential decay of the population, where the data shrinks rather than it grows.
Therefore, the correct option will be B.

How is genetic engineering different from natural reproduction?
Answer:
Genetic Engineering is on purpose.
Explanation:
Genetic engineering could range from selective breeding to adding/removing DNA and RNA. Natural reproduction occurs with the sole purpose of creating successful offspring. The offspring could he tainted if the male and female are related leaving it to not have the DNA or RNA necessary to lessen the likelihood of dysfunctional genetics.
