Explanation:
The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)
Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.
Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.

D. Heterogeneous mixtures
Answer:
A Trailmix is a...
heterogeneous mixture
Explanation:
A heterogeneous mixture contains particles that are not the same, can be separated by physical means, and are not distributed the same throughout the mixture. Trail mix fits this description perfectly.
Trail mix is a heterogeneous mixture, which is in option D, as trail mix is a popular snack that typically consists of a combination of various ingredients, such as dried fruits, nuts, seeds, and sometimes chocolates or candies.
Trail mix is a type of snack that typically consists of a combination of ingredients like dried fruits, nuts, seeds, and sometimes chocolates or candies. These ingredients are intentionally mixed together to provide a variety of flavors, textures, and nutritional elements. Unlike homogeneous mixtures, where the components are uniformly distributed and appear the same throughout, heterogeneous mixtures have visible differences and variations within the mixture. In the case of trail mix, you can see the separation between the various ingredients, and they can be easily distinguished from one another.

The karyotype, or chromosomal profile, for humans is shown. A karyotype can be used to investigate genetic disorders. The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle what is a result if preventing spindle fibers from forming
Answer:
The correct answer is - Mitotic division stops in metaphase and cannot proceed to anaphase.
Explanation:
Spindle fibers do not form during metaphase of cellular division the chromosome would not move in opposite pole and the cell will not move to anaphase.
The chemical colchicine stops the assembling of the microtubules during metaphase of the cell division which prevents the formation of the spindle fibers and the cell did not move to the anaphase from metaphase in mitotic division.

Movement caused by warmer fluids rising and cooler fluids sinking is called ______________.
Answer:
Explanation:
convection current
The movement caused by warmer fluids rising and cooler fluids sinking is called convection currents.
What is convection current?The convection currents are the outcome of differential heating. The less dense, that is, lighter warm substances rise, while the denser, that is, heavier cool substance sinks. It is this movement that generates patterns of circulation called convection currents, in water, in the atmosphere, and in the mantle of the Earth.
Thus, convection currents are the answer.

Answer:

B_ a hindrance
For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.
What is diffraction?
The phenomenon of waves interacting with particles is known as diffraction. This happens when the aperture's or obstacle's size is of the same order of magnitude as the wave's wavelength.
The wave transmitted through an aperture that has a width smaller than its wavelength expands out completely and behaves like a point source of waves.
The small bending of light as it travels around an object's edge is known as diffraction. The ratio of the wavelength of the light to the opening size determines how much bending occurs.
Therefore, For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.

1. Discuss how cells store energy and release energy using ATP. Be specific! Draw the ADP/ATP cycle to help with your explanation
please help,I'm stuck and this is due in a few hours q-q
Answer:
A process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
Explanation:
I actually found this perfect example on the internet. Its the first part to your question.
The hydrolysis of the phosphate bonds in the ATP is used by cells to release energy; whereas the conversion of ADP and phosphate to ATP is used to store energy.
Adenosine thiophosphate (ATP) is the energy coin of the cell.
The hydrolysis of the terminal phosphate bond of ATP is an exergonic reaction that releases energy, which is used by cells to carry out different metabolic functions (e.g. growth, differentiation, reproduction, etc).
When one phosphate group of the ATP molecule is removed by hydrolysis, ATP is converted into ADP and phosphate.
Moreover, during cellular respiration, cells catalyze the formation of phosphate bonds when ADP is combined with phosphate to form ATP.
In conclusion, hydrolysis of the phosphate bonds in the ATP is used by cells to release energy; whereas the conversion of ADP and phosphate to ATP is used to store energy.

If cells don't work together, what would happen to the organism?
Answer:
If cells do not work together, the organism would die.
Explanation:
Production would likewise be impossible if the Golgi did not generate secretory vesicles, thus organisms would perish quickly if cells did not cooperate.
Because secretion would be impossible, a build-up of substances would ensue, causing other compartments in the cell to malfunction.
Food, germs, and bacteria would not be brought into to the cell to decompose down and cause illness.

Plants vs animal Behavior Examples
Answer:
Behavior is the way that all organisms or living things respond to stimuli in their environment. Stimuli include chemicals, heat, light, touch, and gravity. For example, plants respond with growth behavior when light strikes their leaves.
Examples of this kind include the nest-building behavior of birds and the dam-building behavior of beavers. Imprinting. An example of animal behavior that combines instinct and learning is imprinting, often seen in birds such as geese and ducks.
