The question is incomplete and the complete question is attached.
Answer:
Testes
Explanation:
In the given question, the male reproductive structure has been provided and in this male reproductive structure, only "Testes " which occurs in the pairs are known to form the male gametes.
The male gametes called sperms are formed from the spermatocytes which by the process of meiosis produces four spermatozoa which later mature into the spermatids and sperms.
Thus, Testes is correct.
Answer:
Golgi apparatus and extracellular matrix
Explanation:
The Golgi complex lies at the heart of the secretory pathway and is responsible for modifying proteins and lipids, as well as sorting newly synthesized molecules to their correct destination. As a consequence of these important roles, any changes in its proteome can negatively affect its function and in turn lead to disease.
Disruption of specific transport steps between the endoplasmic reticulum (ER), Golgi complex, endosomal-lysosomal system and the plasma membrane all can have dramatic consequences on the cell, and increasingly defects in the molecular machinery regulating membrane traffic are being linked to hereditary diseases.
Any changes to the proteome of the Golgi complex would affect its homeostasis and consequently the flux of proteins trafficking through it.
One possible consequence of mutations in Golgi complex proteins is that they cause gross changes in the morphology of the entire organelle and protein mislocalization, which together result in functional problems such as impairment of glycosylation.
Genetic studies of humans and mice continue to highlight the nonredundant mechanical role of components in complexes that anchor cells to extracellular matrices. At the same time, recent data provide exciting insights into, critical roles of transcription factors in regulating differentiation and function of matrix-producing cells.
The correct answer is C. Virus.
Virus falls on the gray area which is between nonliving and living things.
Virus is referred to as the small infectious agent which replicates only inside the living cells. Virus can infect life forms plants and animals and microorganisms, for example, archaea and bacteria.
They live in form of independent particles which are referred to as virions. Some viruses can evolve from plasmids.
Answer:
Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Therefore, gases take the shape of the container and occupy the complete volume of that particular container.
in question number 6, the correct answer is false. this is because arrow C is representing a combustion reaction whereby hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide. this process is not conversion of chemical energy to mechanical energy. in this process energy will still be stored in form of chemical energy in the bonds of carbon dioxide and water produce
in the question number 7 the correct answer is true. this is because the green plant is using energy from the such for the process of photosynthesis. photosynthesis is a process by which green plants make their own food using energy from the light. light energy is used to split the molecules of water to oxygen and hydrogen ions. oxygen is released into the atmosphere whereas hydrogen ions are used in the dark stage of photosynthesis a process referred to as carbon fixation. the end result of carbon fixation is production of organic compounds such as glucose, protein and lipids among others. these foods store energy in form of chemical energy. so arrow A represents transfer of solar energy to chemical energy
in the question number 8, the arrows that represent the release of carbon dioxide include arrow C and arrow F. in arrow C the process occurring is referred to as combustion and it occurs when hydrocarbon in fossil fuels reaction with oxygen in the presence of heat to produce carbon dioxide and water. the arrow F represents respiration, a process by which living cells manufacture energy in form of ATP from organic food such as glucose. respiration end products include water carbon dioxide and ATP. it is essentially the reverse of photosynthesis
in question number 9, arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel. when plants and animals die and buried deep in the ground, they are slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds.
in question number 10, arrow B & C show the conservation of energy and mass. when living organisms die they are converted to fossil fuels which are used in industries to produce energy required for various activities. during this process carbon dioxide is released into the atmosphere and it is used by plants in the process of photosynthesis as shown by B. this is conservation of energy and mass the number of carbon in the fossils fuel initially came from living plants and when fossil fuel is combusted it produces carbon dioxide that will be used in the process of photosynthesis and cycle continues.
