Which statements help explain how Earth formed as part of the solar system? Select the two correct answers. (1 point)-The denser rocky material in the solar nebula stayed closer to the sun.
-Gaseous planets slowly changed to rocky planets after colliding with meteorites.
-Water and ammonia condensed from gases to ice particles.
-Very large asteroids broke apart to form rocky planets, including Earth.
-The accretion of cosmic dust formed the seeds of planets, including Earth

Answers

The statements 'the accretion of cosmic dust formed the seeds of planets' and 'the denser rocky material in the solar nebula stayed closer to the sun' help explain how Earth formed. It is part of the solar system.

The solar system

The solar system consists of the Sun and eight planets (i.e., Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune).

The solar system is also composed of Pluto (a dwarf planet) many different moons, asteroids, etc.

The solar system formed approximately 4.6 billion years ago from interstellar gas and dust.

Question 6 (1 point)Which of the following are functions of proteins?
short term energy storage
transport
build channels in cell membranes
speed up reactions
long term energy storage
structure

Answers

Final answer:

Proteins have multiple functions in living organisms, including enzymatic activity, transport, and structural support.


Explanation:

Proteins have several important functions in living organisms. They can serve as enzymes, which are molecules that speed up chemical reactions. Proteins can also act as transporters, helping to move molecules and ions across cell membranes. Additionally, proteins are essential for structural support in cells and tissues.

For example, hemoglobin is a protein that transports oxygen in the blood. It binds to oxygen molecules in the lungs and releases them to cells throughout the body. Another example is the sodium-potassium pump, which is a protein that helps maintain the balance of ions inside and outside of cells. This pump is crucial for nerve cell communication and muscle contraction.

Answer:

  1. A yellow lizard population living on an island with no predators
  2. A hawk was introduced to the habitat and starts preying on the yellow lizard because it is easier to see from the air
  3. Some of the lizards mutate their color from yellow to greyish brown so they can camouflage
  4. Yellow individuals keep being hunted, while brown individuals get to survive
  5. The following generations of lizards will have a higher proportion of greyish brown individuals and just a few yellow individuals.  
  6. Eventually, almost all of the lizards will be greyish brown individuals.

Explanation:

The scenario is the following.

A population of yellow lizards lives on an island where there is no natural predator. Males of the species use the yellow color to attract females in reproductive seasons. The brighter the males are, the better their genetic quality is. Females are also yellow, but not as bright as males.

A new hawk species was introduced into the island to control some farm pests. But this hawk species prefer to feed on the lizards. The yellow color of these animals contrasts with the dark background and can be easily seen from the air. So the lizard population suffers from significant predation affecting its size sharply.

Some of the lizards then suffer from a mutation and change their color from yellow to greyish brown, which turns to be better to camouflage on the rocks and get to survive. Individuals with greyish brown color get to reproduce at a higher rate than yellow individuals, who keep being hunted by the hawk.

Eventually, after many generations, the yellow individuals decrease to near zero in the population, while greyish brown individuals increase significantly, with males still being brighter than females.

Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.

When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.

These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.

This change in alleles frequency is what we call adaptation.

Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.

In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.  

So, in the exposed example, we are focussing on the lizards population.    

• The selective pressure or modeling environmental factor is predation by the introduced hawk.  

• The lizards´ response to predation is the survival of only those that carry mutations ⇒ greyish brown color  

• Natural selection benefits these mutations.    

• Greyish brown lizards survive and increase their fitness.

The graph above displays the heights of an average population of humans. Use C.E.R. (Claim, Evidence, Reasoning) to answer the following question:Why is human height expressed in the pattern shown in the graph?

Be sure to identify the inheritance pattern and thoroughly explain how genes & alleles interact to produce this phenotype pattern.

PLEASE READ GRAPH ATTACHED TO THIS thanks

Answers

Answer:

The graph shows the height in inches of determined human population and the pattern it shows is due to the height variations that exist between individuals, due to different factors, where the average height in the population is close to 69 inches, and most of the population has heights between 67 and 72 inches.

Explanation:

The height of individuals is the measurement, from head to toe, which is made standing up and barefoot.

The graph shows the frequency of people who have a specific height, where:

Claim: According to the graph, most people are between 67 and 72 inches tall. Heights below 63 and above 72 inches are less frequent and the average person is about 69 inches tall.

Evidence: The data provided by the graph support the claim that there is variation in height in the human population. When data on anthropometric parameters are to be obtained, a sample is chosen, measured under the same conditions and then taken to a graph showing the results.

Reasoning: variations in human height respond to several factors, mainly genetic and environmental factors.

Inheritance plays an important role in determining an individual's height, although it is a polygenic pattern of inheritance, where multiple genes determine the height an individual will have.

In general, the height between men and women differs but, in addition, the inheritance of this parameter is linked to race. There is no single gene that determines whether a person will be tall or short, nor are there dominant or recessive alleles.

The combination of information from several genes will result in the phenotypic expression of height in an individual and can increases the genetic variability for this trait. It should also be taken into account that genetic disorders can affect the development of normal height.

Environmental factors and habits, especially food and family environment, are determinants of the height a particular individual will have.

Endergonic (energy absorbing) reactionsa. Have more energy in the reactants than in the products

b. Have more energy in the products than in the reactants

c. Are illustrated by the breakdown of glucose (cellular respiration)

d. Can release heat as waste energy

Answers

B. Engergonic reactions absorb energy and store it in the chemical bonds formed, so the products have more free energy then the reactants.
