Answer:
b. volume through shading and perspective
Explanation:
What have the dry gardens (like the one above) been interpreted to represent volume through shading and perspective
O2 or Oxygen gas is released into the environment as a result of photosynthesis.
Answer:
Natural selection
Explanation:
Microevolution refers to changes produced at a lower level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these naturally produced changes by mutation, natural selection, genetic flux, genetic drift.
After the drought on Daphne Major, many of the plants producing small-sized seeds decreased their reproductive rate drastically. Consequently, there were almost no seeds available for the medium ground finch to feed. The population of this species also decreased to only a hundred birds over two years. Weather conditions and food availability influenced the survival of the animals.
With time, the finched population increased again, but now, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.
Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to crack open the husks and eat the contents of the seeds.
<u>Natural selection was responsible for the rapid change in the finches´ population beaks size after the drought. </u>The evolutive force modifies the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.
Corrected Question:
The picture shows the dihybrid cross of 2 guinea pigs.
1. What is the genotype of the parents?
2. What is the phenotype of the parents?
3. What is the genotype of their baby guinea pig (in the empty box)?
a. BbRr - black rough fur
b. Bbrr - black smooth fur
c. bbRr- white rough fur
d. bbrr - white smooth fur
Answer:
Genotype of parents is BbRr as seen in the cross.
Phenotype of the parents is black rough furred.
The genotype of the baby in the empty box is bbRR.
Option D
<h3><u>
Explanation:</u></h3>
This representation of the genetic crossing is called as Punnet square, after the name of the scientist who discovered this process to denote the probability of finding the required genotype in a statistical way.
Here both the parents are heterozygous black and rough furred, with the genotype of BbRr.
So the gametes from the parents are = BR, Br, bR, and br from both the parents which are represented in the Punnet square.
Thus we can get 16 types of genetic combinations among the offsprings.
Answer: The correct option is A (detritus).
Explanation:
The sea star also called the star fish belongs to the phylum echinodermata. They are slow moving marine animals living on the sea-shores and sea beds. They possess tube feet under their arms which enables them to move to location where they can obtain food.
During feeding, the star fish is capable of pouring digestive enzymes on the soft tissue of its prey. Once liquefied, it absorbs it into its stomach. The following are the different types of food that a star fish can feed on:
--> coral,
--> sponges,
--> clams,
--> oysters,
--> sand dollars, and mussels
They also feed on dead or decaying debris of different plants and animals. These dead or decaying debris are also called DETRITUS. A detritus is made up of leaves and other plant parts, animal remains and waste organic products that fall into water bodies from the kelp forests along the North American coastline.
