The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.
<h3>What is the Y-5 molar pattern?</h3>
- This is a distinctive type of molar teeth pattern found in apes and hominoids.
- In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
- Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
- A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
- In bilophodont pattern the tooth is divided into 2 symmetric sections.
- The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

Answer:
38. Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
39. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas
40. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
41. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:
This picture is modeling how animals get nutrients and how it looks. If you look in the photo, you can see many animals and arrows pointing at one another, This shows animals fighting each other. An example would be the girafee, If you look closley the photo is showing the girafee getting nutrients from the tree. This shows the girafee getting the organisms it needs in order to survive.
The recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
<h3>What is a recessive phenotype?</h3>
A recessive phenotype is a phenotype which expresses the recessive trait of a gene.
The recessive phenotype is always h0m0zygous for that triat to be expressed.
In the Hardy-Weinberg equilibrium equation, the allele and phenotype frequencies are given as follows:
where;
- p^2 is the h0m0zygous dominant phenotype frequency
- 2pq is the heterozygous phenotype frequency
- q^2 is the h0m0zygous recessive phenotype frequency
Therefore, the recessive phenotype is used first to determine the q squared value because it is only expressed when h0m0zygous.
