i.e. by fusing with vacuoles from outside the cell.
This could include breaking-down material taken-in by phagocytes, which include many types of white blood cells - also known as leucocytes. Specific mechanisms of heterophagy can be:<span><span>phagocytic - by which cells engulf extracellular debris, bacteria or other particles - only occurs in certain specialized cells</span><span>pinocytic - by which cells engulf extracellular fluid</span><span>endocytic - by which cells take-up particles such as molecules that have become attached to the outer-surface of the cell membrane.</span></span></span><span><span>Recycle the products of biochemical reactions that have taken place following materials being brought into the cell by endocytosis (general term for this 'recycling' function: biosynthesis) </span>
Different materials (chemicals) are processed in different ways, e.g. some structures may be processed/degraded within lysosomes and others are taken to the surface of the cell.</span><span>Completely break-down cells that have died (autolysis)</span></span>
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
Answer:
The correct answer is b. all tall
Explanation:
If the genotype of one parent for height is Tt and another parent is TT then after the fusion of gamete all the offspring will show tall phenotype because all the offspring will have at least one allele of tall character.
T t
T TT Tt
T TT Tt
So after cross two phenotype would be homozygous dominant for tall character and the other two will be heterozygous dominant for tall character. Therefore all the offspring would be tall.
All animals and plants are made of cells. Animal and Plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes.
Mitosis is one of the precious processes. If it goes wrong then the results will be terrible as it can even bring death to the organism or uncontrollable mutation.
Mitosis is the process in which a cell replicates itself to produce a copy of it. As a result of mitosis, each cell carries the copies of the original cell’s DNA.
The uncertain error in mitosis will cause a mutation which affect the amino acid sequence and further functions. This will lead to the cell cycle disruption that can lead to the formation of cancer cells that are uncontrollable in dividing itself.
You failed to include the picture that goes with the question. However, the oldest fossils will be the fossils in the oldest layer, which is the lowest layer of sediment. Sedimentary rock forms as mud and silt pile up over thousands and millions of years. The layers of sediment harden and become rock. Organisms that are trapped in those layers become fossils as additional layers pile on top of them, forming new layers of sediment.
