Answer:
Peptide bonds
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Explain the life cycle of gymnosperms in detail.
Answer: In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.
Hope this helps!
Answer:
The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.

Explanation:
Recent data indicates atmospheric carbon dioxide (CO2) levels are rising. What change in the carbon cycle has most likely caused this increase in atmospheric CO2?
an increase in photosynthesis
a decrease in decomposition by soil bacteria
an increase in burning fossil fuels
a decrease in animal cellular respiration
Answer: The present atmospheric CO2 increase is caused by anthro- pogenic emissions of CO2. About three-quarters of these emissions are due to fossil fuel burning.
56 pages
Explanation:
The increase in burning fossil fuels has most likely caused the recent increase in atmospheric CO2 levels. Therefore, option (C) is correct.
What is carbon cycle?The carbon cycle is the process by which carbon moves between the atmosphere, land, and ocean. Carbon is continuously exchanged between the atmosphere, plants, animals, soil, and the ocean through various processes, such as photosynthesis, respiration, and decomposition
When fossil fuels such as coal, oil, and gas are burned, they release carbon dioxide into the atmosphere that had been locked up in the Earth's crust for millions of years. This addition of carbon dioxide to the atmosphere is not balanced by natural processes such as photosynthesis, which removes carbon dioxide, and respiration and decomposition, which release it. As a result, the concentration of CO2 in the atmosphere has been steadily rising, contributing to global climate change.

When does the mitotic spindle attach to the kinetichore?
Answer:
The Prometaphase.
Explanation:
Typically in biology the prometaphase is overlooked. It is between the prophase and the metaphase, and is the exact point in which the mitotic spindles attach to the kinetochores. Metaphase, which occurs directly afterwards, is when the chromosomes are lined up to be split and pulled towards opposite sides of the cell.

7. ) Most of a cell's growth and activity occurs in the ______ phase.
a.) s phase
b.) m phase
c.) G0
d.) G2
e.) G1
Answer:
Interphase (A.K.A. S Phase)
Explanation:
Hope this helps.
Most of the cell's growth and activity occurs in the S-phase of mitosis. During the S-phase, a cell grows in size and genetic material duplicates. Thus, the correct option is A.
What is Mitosis?Mitosis is the division of cell in which the DNA or the genetic content of the cell remains constant from one generation to the next generation. Mitosis consists of interphase and M-phase. During the interphase, cell prepares for division while in the M-phase the cell undergoes division.
The S phase of a cell cycle occurs during the interphase after the G1 phase, before the M-phase, and it is responsible for the replication of DNA. In this stage, the genetic material of a cell is doubled before it enters the M-phase, allowing enough amount of DNA to be split into the two daughter cells.
Therefore, the correct option is A.

And, Why is water wet?
Answer:
Birds don’t get electrocuted when they land on power lines because the lines are grounded to distant devices, and the current never passes through the birds, because their electrical potential is greater than the ground. If the grounding is removed, then the birds will die.
The reason why The water gets wet Is due to the existence of two forces:"forces of cohesion"which are the forces that have attached to the water particles (H2O) and the"forces of adhesion"are those that are manifested when the water molecules come into contact With another surface.
Explanation:
Answer: They're Not Good Conductors. Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.
Wetness is our description of what we feel when we put our hand in water. Saying water is wet is like saying that wood is hard or fire is hot. Sensory receptors on our hand send information about the water to our brain. But my theory is Water is dry. The reason is becuase, if water touches water, it doesnt get more wet, so its dry.

What causes folded mountains to form?
Collision of continental plates
Collision of a continental plate with an oceanic plate
Vertical shifting along a fault line
Lava emerging from a crack or fissure in the crust
Answer: Fold mountains occur near convergent or compressional plate boundaries. Plate movement creates fold mountains as the plates move towards each other. This movement causes layers of sedimentary rock on the ocean floor to become wrinkled and folded. These mountains are found between two continental plates.

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization
The amount of entropy in a food chain differs between trophic levels the correct option is "B" energy is lost at each level as heat, which increases randomization.
What is the 10 per cent law of energy?The 10% Rule indicates that when energy is flowing in an ecosystem from one trophic level to the next, only ten per cent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.
Thus, energy is lost at each level as heat, which increases randomization.
