Answer:
In human vision, the cone visual opsins are grouped into four photoreceptor protein families LWS, SWS1, SWS2, RH2
.
- SWS1: produce pigments sensitive to very short wavelengths, UV-violet, 360-450 nm.
- SWS2: produce pigments sensitive to short wavelengths, blue, 450-495 nm
- RH2: produce pigments sensitive to medium wavelengths, green, 495-560 nm
- LWS: produce pigments sensitive to long wavelengths, yellow-red, 560-770nm.
Explanation:
Photoreceptor proteins are light-sensitive proteins that mediate light-induced signal transduction, thus they are involved in the sensing and response to light in a variety of organisms.
The photoreceptor proteins are classified based on the chemical structure of the chromophores involved, the light absorption and on the protein sequence.
This photoreceptor proteins are located at the cone photoreceptor cells and are responsible of photopic vision.
For scotopic vision, rhodopsin is responsible. Rhodopsins are the visual pigments (visual purple) of the rod photoreceptor cell in the retina. They are responsible of human vision in dim light, as it contains a sensory protein that converts light into an electric signal.
<span>If a scientist is trying to determine whether the use of cell phone contributes to brain cancer, then the most significant weakness in this type of study is the relationship between the cell phone and brain cancer itself. It is hard to identify its connections and consequences with each other.</span>
Answer:
AGTGGCGTCG
Explanation:
You can go to the genome browser website and search the CDH1 gene, then go to view, DNA, and start in the zero position, then you will find the first ten nucleotides. CDH1 is a human gene that encodes for the protein epithelial cadherin. It is also known to be a tumor suppressor gene, but mutations in this gene can cause various diseases such as gastric, breast, colorectal, thyroid, and ovarian cancers. This gene is located in the chromosome 16, from 68,737,292 bp to 68,835,541 bp.
Answer:
All energy on Earth originally comes from the Sun. Plants use sunlight in a process called photosynthesis, to make their own food and provide energy. This is why plants are producers, because they make their own food. Cows eat plants, namely grass. So, when the cow eats the grass, the energy from the grass transfers to the cow. This is why cows are consumers, because instead of making their own food, cows, like humans, must consume their food to survive.
