Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
Explanation:
- When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
- An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
- An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
- its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.
Answer:
In short, weather is to describe the day or week (short period). . As for the climate, it is to describe the year or (a long period), for example, the climate of the winter season is cold.
Answer:
40 in tail and 20 in egg cells.
Explanation:
If a horse has 40 chromosomes in its heart cells so there will be 40 number of chromosomes in its tail cells and 20 number of chromosomes in its egg cells because tail is also a part of body where mitosis type of cell division occurs means there is diploid number of chromosomes, while on the other hand, egg cells are the reproductive part where meiosis type of cell division occur in which haploid number of chromosomes are present.
Answer: The relationship between species and distance is that more distance or space has more species and less space has less species.
Explanation:
It can easily be understood by taking the example of the island in such a way that the larger islands contains more species than smaller islands.
There are a diversity of species seen in a bigger islands, more in number and more in variety.
It is very important for the studying the various species and its conservation, protection and other factors.
So, more is the distance , more will be the number of species.
