Where does translation take place? where does translation take place? golgi apparatus ribosome endoplasmic reticulum nucleus?
Translation takes place in ribosomes located in the cytoplasm of the cell.
Explanation:Translation is the process of protein synthesis where information coded in the mRNA is used to produce a specific amino acid sequence. It takes place in the ribosomes located in the cytoplasm of the cell. Ribosomes are composed of rRNA (ribosomal RNA) and proteins, and they are responsible for reading the mRNA and assembling the amino acids into a polypeptide chain.
selective breeding is the only method to change life forms characteristics true or false
The assertion that selective breeding is the only way to alter the characteristics of life forms is false because other methods like genetic engineering and natural selection also play a role. Selective breeding, or artificial selection, has been used for millennia but is limited by the genetic variability of complex organisms and can result in unintended trait changes.
The statement that selective breeding is the only method to change life forms' characteristics is false. There are other processes such as genetic engineering and natural selection that also result in changes to an organism's traits. Selective breeding, also known as artificial selection, is a method where humans breed plants or animals with desirable traits to produce offspring that express those traits more strongly. This process has been used for thousands of years, notably in the domestication of various plant and animal species.
However, selective breeding is not without its limitations, especially concerning complex organisms. Such organisms often experience unintentional changes in other characteristics when selectively bred for a particular trait, which could be detrimental. Furthermore, in complex organisms like humans, a very small fraction of genetic variation between individuals limits the range of characteristics that can be selected for at any given time. On the other hand, genetic engineering allows for direct manipulation of DNA to achieve desired traits, and natural selection involves the differential survival and reproduction of individuals due to differences in phenotype.
Therefore, while selective breeding can induce change in an organism's traits, it is by no means the sole method available for such modification.

Why is it important for plants to have mechanisms to prevent self-fertilization?
It is important for plants to have mechanism to prevent self fertilization in order to establish genetic diversity else homozygosity will be there without any variations.
What do you understand by self-fertilization ?Self-fertilization refers to the union of male and female gametes (sex cells) produced by the same person. Bisexual organisms, including the majority of flowering plants, self-fertilize.
Self-fertilization functions as an evolutionary and reproductive mechanism that enables an isolated individual to establish a local population and stabilize desirable genetic strains, but it falls short of supplying a significant amount of variability within a population, limiting the potential for adaptation to environmental change.
Therefore, mechanism to prevent self fertilization is important in plants.

The phylum __________ contains both invertebrate and vertebrate groups.
The phylum Chordata contains both invertebrate and vertebrate groups, including fish, amphibians, reptiles, birds, and mammals.
Explanation:The phylum Chordata contains both invertebrate and vertebrate groups. Vertebrates, which have a backbone, are a subgroup within the phylum Chordata. They include organisms such as fish, amphibians, reptiles, birds, and mammals. In addition, the phylum Chordata also includes two clades of invertebrates known as Urochordata (tunicates) and Cephalochordata (lancelets).
Phylum Chordata encompasses animals with distinct features: a notochord, dorsal nerve cord, pharyngeal slits, and a post-an-al tail. Thus, these traits are evident in diverse subgroups like mammals, birds, fish, and amphibians. Chordates exhibit remarkable anatomical diversity, adapting to various environments while sharing a common evolutionary ancestry.
Measles became prevalent only with the emergence of larger urban centers, making it the "disease of civilization."
a. True
b. False
Final answer:
Measles becoming prevalent with the emergence of urban centers is true.
Explanation:
The statement that measles became prevalent only with the emergence of larger urban centers, making it the 'disease of civilization,' is True. Measles is a classic example of an infectious disease that thrives in larger populations. Measles requires a large contiguous population to keep it going, and it would not have been able to survive in smaller hunter-gatherer groups. The increase in the size and density of human populations in urban areas facilitated the spread of measles and other infectious diseases.

After leaving the stomach, chyme passes into the first segment of the small intestine called the ________
After leaving the stomach, chyme passes into the first segment of the small intestine called as the duodenum. Most of the food is absorbed in this region of small intestine of the digestive system.
What is Digestion?
Digestion is the process of breakdown of the large insoluble food molecules into small water-soluble molecules which helps in absorbing the food particles into watery blood plasma. In some organisms, the smaller water-soluble substances are absorbed through the small intestine into the blood stream directly.
The small intestine makes all the digestive juices which mixes with the bile and pancreatic juice to complete breakdown of complex compounds such as proteins, carbohydrates, and fats. Bacteria present in the small intestine make some of the enzymes required in the digestion of carbohydrates.

Identify the first step of the Calvin cycle and DESCRIBE what happens?
Final answer:
The initial step of the Calvin cycle is carbon fixation, where CO₂ is attached to RuBP to form a six-carbon compound that splits into two molecules of 3-PGA, catalyzed by the enzyme rubisco, setting the stage for the subsequent sugar production using ATP and NADPH.
Explanation:
The first step of the Calvin cycle is known as carbon fixation. During this phase, CO₂ from the atmosphere is attached to a five-carbon molecule called ribulose-1,5-bisphosphate (RuBP). This reaction is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as rubisco. The result is a six-carbon compound that immediately splits into two three-carbon molecules of 3-phosphoglycerate (3-PGA). This is how CO₂ is 'fixed' from its inorganic form into an organic molecule, which can then be further transformed through the Calvin cycle with the help of energy carriers ATP and NADPH generated during the light reactions of photosynthesis. These energy carriers provide the necessary energy to eventually transform the 3-PGA molecules into glucose.
