Answer and Explanation:
A gene is a section of DNA. The change in the sequence of the DNA is known as mutation. Mutation always changes the sequence of the DNA. Sunlight can cause mutation. Sunlight produces structures named thymine dimers. Thymine dimers produce twist in the shape of DNA. These twists make DNA hard to copy, which can lead to mutation. It is essential to use sunscreen to block UVA and UVB rays to prevent thymine dimers from emerging in our cells. The US Food and Drug Agency recommends an SPF (sun protection factor) to defend against skin aging and skin cancer. X-ray radiation is a form used in x-rays. The energy level of the X-ray radiation is very high that can produce free radicals. Free radicals can steal electrons from DNA that can cause mutation. By using medical images, we can decrease exposure to X-rays. Less exposure to X-rays prevents mutation and also prevents the production of gene protein in other body parts.
Answer:
Codominance
Explanation:
Codominance occurs when two heterozygous allele for a trait is expressed equally in the an organism's phenotype with neither allele being dominant or recessive. In codominance, none of the allele hides the expression of the other allele. So when two alleles are crossed, the offspring carries a combination of the parents phenotype without anyone masking the other.
From the question, the type of genetic pattern of the leopard geckos display is codominance.
Answer:
Gila monsters are only found in the Sonoran, Mojave and Chihuahuan deserts in the southwestern United States and northwestern Mexico.
Explanation:
Basically a desert
The blood carries carbon dioxide away from the cells
Answer: The correct answer would be corpus albicans.
Explanation:
After ovulation, the ovarian follicle converts into corpus hemorrhagicum. After some time, it converts into a temporary endocrine structure termed as corpus luteum. It maintains high levels of progesterone which is necessary for maintenance of uterus lining.
However, in absence of pregnancy or fertilisation, the corpus luteum starts degrading and convert into the structure termed as corpus albicans.
