Answer:
Technology is also being harnessed to help prevent food waste, working to keep food out of landfills by keeping better track of it at all levels, from the farm to the table. With up to a third of the world's food resources thrown out, data collection technology has the potential to greatly reduce that figure.
Answer:
A bright light close to the plant.
Explanation
Plants grown in bright light had higher rates of apparent photosynthesis per unit leaf area in bright light, and slightly lower rates in dim light than did those of plants grown in dim light. Dark respiration rates were higher in plants grown in bright light than in plants grown in dim light and the decline of photosynthesis with increasing leaf age was faster.
The rate of apparent photosynthesis in bright light of the first leaf to become fully expanded after plants were transferred from bright to dim light was lower than that of plants remaining in bright light. The decline in the rate of photosynthesis of a leaf already fully expanded at the time of transfer was not affected. Transferring from dim to bright light increased the rate of photosynthesis of the next expanded leaf; it also increased the rate of an already fully expanded leaf during the first week in bright light.
function of endosperm include in dicots like peas and beans food is stored in cotyledons not in endosperm that is why it is absent in dicots
Endosperm developed from the triploid cell (3n) in the embryo sac where the second male gamete fuses with the diploid secondary nucleus to form primary endosperm nucleus (PEN) and a triploid cell which is called as triple fusion
Endospermic cells are mostly triploid but in some plants, they may be diploid (water lily) or polyploid (up to 15n)
In some of the dicots, mature seeds contain food stored in the endosperm, they are called endospermic or albuminous seeds, e.g. castor
In beans, peas, gram seeds, the endosperm is completely absorbed during development and food is stored in two cotyledons. They are called exalbuminous seeds
Endosperm mostly contains starch as a food reserve, but it may contain fats, e.g. castor, Endosperm provide nutrients to seeds during dormancy
Endosperm also contains certain hormones like cytokinins and helps in cell differentiation

b. They burst as one to move from outside to inside the cells as a result of osmosis
c. No change occurs as water freely diffuses back-and-forth across the cells membrane
d. DeSales expand energy pumping water out in response to the great external salt concentration
Answer:
The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.
Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.
In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.
Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.
If we place human red blood cells in a concentrated salt solution, then they shrink as water moves from inside to outside the cells as a result of osmosis.
Further Explanation:
Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.
For a cell to survive, the ion concentrations outside and inside the cell should be the same. Also, the water concentration is limited because a higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi-permeable. Also, focus on maintaining the equilibrium on both sides and prevent the bursting of the cell. If a blood cell is placed in a beaker that is filled with the concentrated salt solution then the solvent present in the cell moves outside to the cell to maintain the homeostasis of the cell this phenomenon is mainly known as exo-osmosis.

Humans have a tailbone that is not visible during embryonic development, which suggests that humans evolved to not depend on their tailbone serving a useful purpose.
Humans do not have gills as fish do, but human embryos have gill slits, suggesting humans and fish share a common evolutionary ancestor.
Humans have embryonic cells that develo
Answer:
If I am correct, C would be your answer.
The correct option is D.
A virus refers to an infectious micro organism that is made up of nucleic acid molecule that is enclosed within a protein coat. Viruses are only able to reproduce and multiply when they come in contact with living cells, in the absence of living cells they remain dormant and they do not show any sign of been a living thing. The nuclei acid molecule of a virus can be in form of a DNA molecule or a RNA molecule.
Answer: The answer is D/RNA or DNA core surrounded by a protein coat.
Explanation: One reason a virus is considered to be a particle rather than a cell is because structurally it is only a RNA or DNA core surrounded by a protein coat. It has none of the other features of bacterial cells.
a: bird
b: fish
c: amphibian
d: insect
e: mollusk
f: mammal
g: reptile
h: none of these
The classifications of the below-illustrated organisms are as follows:
The characteristics of reptiles are as follows:
Mammals are mammary glands in order to feed their young ones. Amphibians have the ability to live in both water and terrestrial habitats. They have two pairs of limbs. The Body is divisible into the head and trunk.
Birds are classified into the category of Aves. The presence of feathers is one of the most important characteristics of this type of classification.
Therefore, the classifications of the below-illustrated organisms are mentioned above very briefly.
