What is a specific example of competitive advantage exhibited by Darwin’s finches?(1 point)
Birds have one of two forms of the HMGA2 gene.
Female finches mated with males that had similar-sized beak
All of the finches evolved from one ancestral species and adapted to their specific niche.
Medium ground finches with small beaks survived multiple droughts.
Answer:
Explanation:
All of the finches evolved from one ancestral species and adapted to their specific niche. of them evolved from one ancestral species, which colonized the islands only a few million years ago.
Darwin's finches, which was residing in the Galapagos archipelago and Cocos island, constitute an iconic model for studies of speciation and adaptive evolution. All of the finches evolved from one ancestral species and adapted to their specific niche.
What are the characteristics of Darwin's finches?The evolutionary history of Darwin's finches is identified by a gene that explains variation in beak shape within and among species.
The major factor influencing the survival of the medium ground finches is weather and the availability of food.
As all of the finches evolved from a single ancestral species and adapted to their specific niche, it is a specific example of competitive advantage exhibited by Darwin’s finches.
Thus, the correct option is C.

PROCESS BY WHICH PLANTS MAKE THEIR OWN FOOD WITH THE HELP OF WATER, MINERAL , CHLOROPHYLL CARBON DIOXIDE IN THE PRESENCE OF SUNLIGHT IS CALLED PHOTOSYNTHESIS.I HOPE IT IS HELPFULCell processes that increase the surface area of a cell are called:
Answer:
Answer below
Explanation:
As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly).Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration.These foldings too increase the surface area.Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
Non-motile cilia are structures in a cell membrane that also increase surface area. Non-motile cilia are like oars that push through the cell membrane. They are thinner and longer than microvilli. Non-motile cilia are also called primary cilia.

Explain why the wound of a diabetic patients fails to heal heal easily?
[tex]\large\huge\green{\sf{Answer:-}}[/tex]
When white blood cells are unable to function correctly, the body is less able to fight bacteria and close wounds. People with uncontrolled diabetes may develop poor circulation. As circulation slows down, blood moves more slowly, which makes it more difficult for the body to deliver nutrients to wounds.

How does a plants structure contribute to its ability to perform photosynthesis
Answer: 1. Leaves have a large surface area; this allows them to absorb more sunlight. They are also thin, meaning that carbon dioxide has a shorter way to travel.
2. stomata allow the entrance of carbon dioxide. The more complex adaptations are of the internal leaf structure.

Define bronchiole and alveoli.
Answer:
[tex]\huge\purple{\overline{\quad\quad\quad\quad\quad\quad\quad\quad\quad \ \ \ }}[/tex]
Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.
When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.
Answer:
The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;
This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)
