Answer:
1) Firstly, lets sort out the alleles for the dominant and recessive characteristics. The dominant brown allele will be written as B and the recessive red hair allele will be written as b.
2) Lets sort out the genotype of the parents. The parent having homozygous brown coloured hair will carry the alleles BB. The parent carrying the heterozygous brown coloured hair will carry the alleles Bb.
3) The punnet square from these parents will be drawn as follows:
B b
B BB Bb
B BB Bb
4) Now, lets predict the phenotype of the offsprings. The results from the punnet square show that all of the offsprings will have brown coloured hair.
5) The genotype for the children will have 50% chance to be homozygous brown (BB) and 50% chance to be heterozygous brown (Bb).
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins
Prokaryotic cells do not have a nucleus, animals cells have a nucleus and plant cells have a nucleus. Animal cells and plant cells are both eukaryotic.
Complete question: This can be seen in the attached file below. It's contains the various protists observed in the exercise.
Answer: For a eukaryotic organism to possess a plantlike characteristics shows its ability to manufacture its own food through the process of photosynthesis.
Explanation:
Protists are single- celled or unicellular organisms. They are made up of eucaryotic cells in which the cell structure is complex with a well - defined nucleus. Typical example if protists includes the following:
--> Volvox
--> Spirogyra
--> Euglena
--> Diatoms
--> chlamydomonas
Some protists are said to be plant like and are known as protophyta. Example of such includes Euglena, Spirogyra and chlamydomonas. This is because they have organelles called chloroplasts. This contains chlorophyll which enables them to make their own food through the process of photosynthesis. Photosynthesis is the process by which energy for sunlight is converted to high energy containing organic compounds such as glucose.
