The answer is; Porosity which affects soil texture
The largest particle size is referred to as sand, medium is silt, while the small particles are clay. Soil texture is determined by the ratio of these three in its mixture. Soil with a higher proportion of clay becomes waterlogged easily when it rains. The right kind of soil for farming is loam because it is well drained.
I think the correct answer would be the first option. It is the carbohydrates that is used as markers by cells to help recognize each other. Sugar chains are being used by the cells which are found on the outer membrane to help identify other cells.
Answer:
Parenchyma cells are the abundant cells that make up ground tissues in plants.They are flat at point of contact.they have thin primary cell walls and have large vacuoles for storage of food.In leaves they are called mesophyll and are sites of photosynthesis.In other parts they are sites for respiration and protein synthesis.
Sclerenchyma cells are cells with rigid secondary cell walls.Their cell walls are hardened with lignin which is the main chemical component of wood.Mature sclerenchyma cells cannot elongate and most of them are dead.
Explanation:
Answer:
It’s important to avoid extra costs, time and wrong knowledge/ idea.
Explanation:
I think the source of information related to job are important for the concerned people in order to enable them have the best view and position on jobs available. This helps them to weigh their options very well before taking decisive actions.
It also helps to avoid extra costs, time and wrong knowledge/ idea which in turn promotes general efficiency of such group of people.
The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".
<u>Option: B</u>
<u>Explanation:</u>
In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.
Chromosomal mutations are often caused by chemical agents or by mutagens.
The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
