Answer: True
Succession is the phenomena in which changes in the biotic and abiotic factors of the environment leads to change in the ecosystem. A succession is a process in which a biological community is replaced by another biological community until a mature ecosystem is formed this process is influence by environmental factors. Primary succession is the primitive environment where no biotic community previously existed it is followed by secondary and subsequent succession were life forms develop and form an ecosystem. Some of the environmental factors are:
Topographical : These are the change in the region or habitat were succession occurs. Landslides, volcanic eruption, glacier melting etc. are the examples , as these topographical changes can bring reformation of the landscape. The disturbance caused by these topographical changes will allow the disturbance tolerant species to repopulate the habitat. This can be a transition from primary to secondary succession.
Soil : It is an abiotic factor.The growth of the plants requires suitable soil conditions. The type of soil will affect which species will inhabit the area. The soil moisture and pH greatly affect the number of plant species in an area.
Climate : It can influence the direction of succession. Climatic factors includes rain, wind etc. For example a region lacking proper rainfall the species will be tolerant to dry and drought conditions. The region with heavy rainfall, the species will be more tolerant to moisture. Wind being a climatic factor can cause wind erosion affect the soil quality. Wind can lead to heavy forest fires can therefore, wiped out community.
Succession takes place when environmental factors affecting an ecosystem change. Therefore, the given statement is true.
Succession refers to the process of ecological change over time in a particular area or habitat. It involves the progressive and predictable sequence of changes in species composition and community structure, leading to the development of a stable and mature ecosystem.
It can occur in both terrestrial and aquatic ecosystems. It is typically categorized into two main types: primary succession and secondary succession. It is a dynamic process.

The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
Answer: 50
Explanation:-
Proteins are polymers which are very critical for the normal functioning of the human body. They are essential for the structure, function, and regulation of the body’s tissues and organs.
Proteins are made up of number of smaller units called amino acids that are attached to one another by peptide bonds and thus form a long chain of polymer called as protein.
A protein at least 40 amino amino joined together by peptide bond is known as protein.
A) a defect in the synthesis of the glucose-6-phosphate dehydrogenase
B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus
C) a defect in the releasing small molecules from digested materials into the cytosol
D) a defect in a hydrolytic enzyme that breaks down polysaccharide
E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases
F) a defect in the mannose-6-phosphate receptor in the mitochondria
Answer:
B); D) and E)
Explanation:
B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus.
Explanation: The mannose-6-phosphate receptors (MPR's) in the Golgi apparatus are essential for targeting the mannose-6-phosphate tagged lysosomal proteins to the lysosome.
D) a defect in a hydrolytic enzyme that breaks down polysaccharide.
Explanation: Lysosomes contain enzymes that hydrolyze polysaccharides, therefore any defects in these enzymes causes malfunctioning of the lysosome.
E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases.
Explanation: In the Golgi apparatus lysosomal proteins are tagged with mannose-6-phosphate so that they are specifically transported to the lysosomes.
Answer:
C. Accidents
Explanation:
The latest UN surveys show that traffic accidents are the leading cause of death among 15- and 29-year-olds in the United States. According to official data, more than 1.2 million people lose their lives in traffic accidents every year. The numbers are frightening and show that the problem of traffic negligence is still very much highlighted. Young people are among the hardest hit because of the lifestyle to which they are generally associated. Drunk driving and speeding are the main causes of accidents among young people. However, driving and using your mobile phone to send instant messages begins to appear as a major trigger for accidents.
