Answer:
d. xylem and phloem
Explanation: plants possess vascular bundles.these are bundles which includes xylem and phloem tissues and transport useful substances to various plant cells.
New Xylem and phloem are formed from the vascular cambium which divides into new cells .
Xylem and phloem are thin and slender with pipe-like structure.
The xylem transports water and dissolved nutrients to the cells where they are needed.
The phloem transports the product of photosynthesis (sugar) to parts what they are used up or stored .
Xylem cells are dead and consists in vessels,trachieds and xylem parenchyma.
Phloem cells are dead and consists in sieves cell, companion cells, phloem parenchyma and phloem fibres.
Refined carbohydrates tend to be much in lower in
fiber and vitamins than whole grains. These are complex carbs that have had fiber removed from them
leaving reproduce simple carbohydrates. These are rapidly absorbed causing a
blood sugar increase, which is followed by some crash. During the milling
process, the germ and bran is peeled and the grain's endosperm is crushed. The
final product becomes easier to gnaw and digest. The main reason manufacturers
process the grain is to lengthen shell life.
Answer:
The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.
Explanation:
This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.
According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.
This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.
Since living organisms require energy and both survival and reproduction... the sun provides the energy for photosynthesis. Cells need sugar as a sources of energy. The cellular respiration is the synthesis of ATP using energy that is being released by the breakdown of sugar to carbon dioxide and water.
B.cyanobacteria
hope it is correct
