A disaccharide is formed when two monosaccharides are joined together by
Monosaccharides and disaccharides are the monomeric units of carbohydrates. The two units of monomers are joined by a glycosidic bond.
Carbohydrates are biomolecules, which are made up of monomeric units, known as monosaccharides. These monomeric units like glucose join together to form maltose.
The bond between the monosaccharides is glycosidic. It is formed by the dehydration synthesis reaction, in which one monosaccharide (glucose) will lose H-atom, and the other (glucose) will lose an OH-group. Thus, it leads to the elimination of water molecules, and new covalent bonds are formed.
Therefore, monosaccharides are joined by glycosidic bonds.

An energy pyramid shows that about 90 percent of the energy represented in each trophic level is
A. passed on to the level above it.
B. used by decomposers.
C. lost to the environment as heat.
D. recycled by the ecosystem.
Approximately 90 percent of energy at any given trophic level in an ecosystem is lost to the environment as heat, making only about 10 percent available to the next higher trophic level. Consequently, food chains typically consist of no more than four or five levels due to this energy limitation. Option C. lost to the environment as heat.
An energy pyramid shows the transfer of energy among different trophic levels in an ecosystem. According to this concept, approximately 10 percent of the energy at one trophic level is passed on to the next higher level. This means that about 90 percent of the energy at each trophic level is either used by organisms for metabolism, growth, and repair, or lost to the environment as heat. In other words, the correct answer to what happens to about 90 percent of the energy in each trophic level is C. lost to the environment as heat.
The energy loss through metabolic processes is primarily in the form of heat, which is then dissipated into the surroundings and cannot be reused by the ecosystem. This inefficiency in energy transfer is the reason why food chains or webs rarely have more than four or five trophic levels - there simply isn't enough energy remaining to support additional levels beyond that.

Answer: Reproduction
Explanation:
Every living organism lives and death is also an important part of life cycle. As it is known that the organism that is born will die some day, in doing so they will extinct.
The organism reproduce in order to maintain a significant number in the environment. If the number of birth will be equal to the number of deaths then there will be a equilibrium between the deaths and birth of organism.
Hence, the correct answer is reproduction.
Body cell mutations cannot be passed on to offspring. This is because body cells do not contribute genetic material to A. daughter cells. B. non-mutant cells. C. sex cells. D. each other.
The right answer is C. sex cells.
Like all cells, a somatic cell can mutate.
* A somatic mutation, if it is "viable" (if it does not kill the cell, organ or organism that carries it), and if it is not controlled by the body (apoptosis, confinement of the mutated cell) can give rise to new identical cell lines, thus carrying the same mutation.
* In so-called evolved animals (which can not clone naturally), this mutation affects only the organ or the organism concerned, but will not be transmitted to the offspring of the individual.

In angiosperms, flowers are adaptations for reproduction. Which of the following does NOT usually describe flowers that are pollinated by animals? A. They are tiny.
B. They pollinate more efficiently than wind-pollinated plants.
C. They produce nectar to attract pollinators.
D. They are brightly colored
Ans. (A). They are tiny.
Angiosperms are seed-producing, flowering plants. The flowers are adaptive structures that help in reproduction. The flowers attract pollinators (animals, birds, or insects) that transfer the pollen grains from anther (male organ) to stigma (female organ).
Flowers, which get pollinated by animals or birds are bright in color, produce nectar and scent to attract pollinators. These flowers are generally larger in size. Pollination by animals is more efficient than wild pollination as many pollen get wasted during wind pollination.
Thus, the correct answer is option (A).
Two nuclei now form, followed by cytokinesis. how many chromosomes are in each nucleus
It depends upon what type of cell which underwent the division. If it is a somatic cell and it underwent mitosis, the number of chromosomes remains unchanged at 46 in each cell. On the other hand, if it is a sex cell, the number of chromosomes is halved (23) after meiosis. By the way, mitosis is the term for cell division among somatic cells and meiosis is for the sex cells.
