The organelle the question is referring to is called the chloroplast. I hope this helps; have a good evening!
Answer:healthy plants
Explanation:the farmers use raw manure on their fields because it is an excellent source of nitrogen (N), phosphorus (P) and potassium (K), which are all nutrients necessary for plants to grow and thrive.
Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
Answer:cacti
Explanation:
In an ecosystem,the ultimate source of energy is the sun. Plants take up this energy from the sun to produce food. Animals eats up plants and when they die ,they decompose. This continuing process leads to the transfer of energy from one trophic level to another in the ecosystem.
Plants ,algae and some bacteria are the primary producers in the ecosystem.they are able to make their own food and support the entire living system. They extract inorganic nutrients and energy from the environment, in order to make their food. Animals(herbivores) eats up the plants and other animals(carnivores) eat up such animals. This situation sets up a chain of flow of energy from the producer to the consumer and back to the environment.
Answer:
How do proteins adopt and maintain a stable folded structure? What features of the protein amino acid sequence determine the stability of the folded structure?
Proteins are formed by three-dimensional structures (twisted, folded or rolled over themselves) determined by the sequence of amino acids which are linked by peptide bonds. Among these bonds, what determines the most stable conformation of proteins is their tendency to maintain a native conformation, which are stabilized by chemical interactions such as: disulfide bonds, H bonds, ionic bonds and hydrophobic interactions.
How does disruption of that structure lead to protein deposition diseases such as amyloidosis, Alzheimer's disease, and Parkinson's disease?
The accumulation of poorly folded proteins can cause amyloid diseases, a group of several common diseases, including Alzheimer's disease and Parkinson's disease. As the human being ages, the balance of protein synthesis, folding and degradation is disturbed, which causes the accumulation of poorly folded proteins in aggregates, which can manifest itself in the nervous system and in peripheral tissues. The genes and protein products involved in these diseases are called amyloidogenic and all of these diseases have in common the expression of a protein outside its normal context. In all these diseases, protein aggregation can be caused by mere chance, by protein hyperphosphorylation, by mutations that make the protein unstable, or by an unregulated or pathological increase in the concentration of some of these proteins between cells. These imbalances in concentration can be caused by mutations of the amyloidogenic genes, changes in the amino acid sequence of the protein or by deficiencies in the proteasome.
