Can someone help me with that question
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.

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.

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.

In man, hitchhiker's thumb is domiant to a straight thumb, and brown eyes is dominat to blue eyes. If a man that has a straight thumb and brown eyes in the heterozygous form marries a woman that is heterozygous for hitchhiker's thumb and blue eyes, what is the chance that one of their children will have a straight thumb and blue eyes?
Answer:
25%
Explanation:
T = Hitchhiker's thumb
t = straight thumb
B = Brown eyes
b = blue eyes
The man's genotype is ttBb
The woman's genotype is Ttbb
Make a dihybrid punnett square to find the possible genotypes of the offspring
ttbb is straight thumb and blue eyes. There are 4 out of 16 genotypes with this phenotype so:
Divide 4 with 16 and multiply by 100 to get the percentage of offspring with that phenotype
4 ÷ 16 = 0.25
0.25 × 100 = 25%

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.
