James is researching the advantages of varying beak sizes of four bird species in a local habitat. He records and graphs the data to show how many individuals there are in each species with different sizes of beak. The graph is provided. If all four species of birds are transported to a new habitat with completely new food sources, which species will most likely be able to avoid extinction?
Answer:
The birds with long pointed beaks.
Explain:
Birds beaks developed different tastes for fruits, seeds, or insects picked from the ground or cacti. Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.
Birds with larger, thicker beaks are better adapted to crush and open seeds and foods that are larger. So a bird with a small beak could not eat it.

The pattern observed when a heterozygote does not show the trait associated with the dominant allele is
Co-dominance will make the pattern expected for the dominant allele to control the observed trait not to occur.
What is allele?Genes occur in pairs. These pairs of genes determine which traits are expressed in an organism. The allele has a dominant gene and a recessive gene.
Sometimes, the pattern that is expected in which the dominant gene is expressed is not observed due to codominance.

Answer:
fine details such as the wings, legs and other fragile structures are preserved effectively giving us a window into how the preserved organism would have appeared in life. without the presence of amber, we wouldn't be able to examine a majority of small prehistoric organisms.
Explanation: amber is able to preserve a snapshot of the ancient world in ways that other forms of fossilization simple fails to do. while an imprint of a feather could be preserved in rock the actual feather could be captured within amber. Amber also preserves small organisms that otherwise would have been lost to time such as the insects seen in the photo above. And much like the gecko seen below it can show us how these organisms truly appeared in life.

Describe the process that causes the cloud type
shown to reach heights of over 6000 m.
Answer:
Explanation:
Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

What is a major impact of climate change for fish species
Answer:
a major impact is the temperature rise or drop in certain oceans
Explanation:
trust me bro
The main impact of climate change on fish species is the increase in water temperature.
How does temperature affect fish?
The metabolism of fish is higher as the temperature increases, causing their food consumption to increase in the hot seasons of the year and, consequently, at these times, their growth rate also increases.
With this information, we can conclude that the main impact of climate change on fish species is the increase in water temperature.

Organelles is not a living things A. True B. False
Answer:
Organelles are not considered a living being. They do not contain their own DNA.
Explanation:
Suffice to say this is a touchy question due to the controversy of life itself within an Organelle. Organelles cannot replicate and are lipid/protein constructs. Naturally a living being should be able to replicate whether it be by its own self or with a partner.
Identify the phrase that best describes a transfer of energy between the hydrosphere and the atmosphere. Ocean currents transport warm water from the equator to the poles and cold water from the poles to the tropics. These currents help regulate air temperatures and, therefore, the global climate, counteracting the uneven distribution of solar radiation reaching Earth. If there were no currents, the temperature near the equator would be extremely hot, and the temperature near the poles would be extremely cold. These areas would not be suitable for living things to survive.
These currents help regulate air temperatures and, therefore, the global climate, counteracting the uneven distribution of solar radiation reaching Earth.
What is a hydrosphere?The hydrosphere consists of water forms and all water layers of the earth.
Examples are oceans, seas, rivers, lakes, etc.
Ocean currents help in the transfer of energy between the hydrosphere and the atmosphere.
It also regulates the temperature of the air.
Thus, the correct option is B, Ocean currents help regulate air temperatures and, therefore, the global climate, counteracting the uneven distribution of solar radiation reaching Earth.

1. ALL cells have the SAME genes. True/False Provide an example of this in humans: Answer here..
2. DIFFERENT genes are active in DIFFERENT cells. True/False Provide an example of this in humans: Answer here..
3. DIFFERENT genes are active at DIFFERENT time. True/False Provide an example of this in humans: Answer here..
Answer:
Explanation:
1. True, all cells in one body do have the same genes. AN example is keratin or collagen. Collagen is produced in the skin, is you have brown hair it is expressed but if you have black hair it is repressed.
2. I believe this one is true I am not sure. Every cell has a different duty but the same genetic instructions. Different types of genes can be turned off and on by different cells. The liver cells are different from the nerve cells but still have the same DNA in your body.
3. True! An example is when you are young you are growing but those genes stop when you are an adult and stop growing taller.
f. What happens to the PGAL molecule that does not continue on in the Calvin cycle?
Answer:
The cell uses it to produce glucose and other biomolecules.
Explanation:
The regeneration of significant quantities of RuBP using PGAL molecules allows the Calvin cycle processes to be repeated. The rearrangement of carbon atoms in three-carbon containing molecules to produce five-carbon molecules is required for RuBP regeneration from PGAL.
