A hydrocarbon consists of four carbon atoms with one double bond. Predict the molecular formula of this compound.
the awnser would be c4h8
Answer:
rod photoreceptors
Explanation:
The retina of the eye has 2 types of sensory receptors or photoreceptors. They are the rod cells and the cone cells. The rod cells mostly found at the outer edge of the retina of the eye, which are numerous and more sensitive compared to the cone cells. The cone photoreceptors are found in the macula.
The rod photoreceptors are responsible for night vision mainly and function in dim light or less intense light, while the cone receptors are responsible for color sensitivity.
The rod photoreceptors are responsible for processing his ability to see objects in the darkness.
significance in commercial products such as cheese and yogurt
sewage disposal
nitrogen fixation
Answer: All the four
Bacteria are single celled simple prokaryotic organisms. They perform different roles in nature:
1. decomposition: It is a process in which the complex organic matter from dead remains of plants and animals is converted into simple molecules. Many bacterial agents participate in this process, in order to obtain their nourishment. Decomposition is a natural waste management process.
2.significance in commercial products such as cheese and yogurt: Bacterial strain named as Lactobacillus is used in dairy products like cheese and yogurt. Bacteria are used to make organic acids in pickles and vinegar. Sourdough bread is made by the fermentation process of the yeast and bacteria is also used as an ingredient.
3.sewage disposal: The decomposing nature of the bacteria facilitates the degradation of organic waste present in the sewage. Therefore, they help in sewage waste management or disposal.
4. nitrogen fixation: Some bacteria lives in symbiotic relationship with plants, especially with leguminous plants. The bacteria trap the atmospheric nitrogen from the environment and supply it to plants, which is necessary for growth, in return the bacteria receives nutrition from plants.
Therefore, all the four options are correct.
In general, the functions of lysosomes involve breaking-down i.e. processing to 'make safe' or make use of, or removing from the cell e.g. by exocytosis, useless and potentially harmful materials such as old worn-out parts of the cell or potential threats such bacteria. Lysosomes can therefore be thought of as the rubbish disposal units within cel

b. presence of complex organisms
c. conditions suitable for all organisms
d. experiences no change
Answer: d. experience no change
Explanation:
An ecological succession is a phenomena of gradual changes that occur in the biotic community of the ecosystem with respect to changes occurring in non-living components of the environment in a particular time frame until the ecosystem attains stability.
A climax community is the community which develops at the end of the ecological succession. It is the stage of ecological succession which does not require any change in terms of biotic community and the surrounding non-living environment.
(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.
Answer:
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
Explanation:
The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.
This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!
The letter C in the graph represents the zone of physiological stress.
The zone of physiological stress is the range of environmental conditions in which an organism can survive, but at a reduced level of function. In the graph, this range is represented by the area between the optimal range (zone of optimal performance) and the zone of intolerance.
In the zone of physiological stress, organisms may experience a variety of negative effects, such as reduced growth, reproduction, and immunity. They may also be more susceptible to diseases and other environmental stressors.
The zone of physiological stress varies depending on the species and the environmental factor in question. For example, some species are more tolerant of heat stress than others. Similarly, some environmental factors, such as temperature, have a greater impact on physiological stress than others.
