18-23 days
Answer :
Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.

1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?
Answer:
1. 50%
2. Every gamete only contains 50% of the genetic information or half of the information for a gene.
Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.
2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well
Heterogeneous means different
Here they are 2Total 4Percentage:-.

Essential Question: What is the relationship between photosynthesis
and respiration?
*Zoom in to the picture for a better view
Answer:
I. Examine Details
1. In what cell organelle does photosynthesis occur? cellular respiration?
Photosynthesis occurs in the chloroplast, while cellular respiration occurs in the mitochondria.
2. What are the three things needed for photosynthesis? Highlight them on the diagram in green.
Sunlight, carbon dioxide, and water
3. What are the two products of photosynthesis? Highlight yellow.
Glucose and oxygen
4. What are the two things needed for cellular respiration? Highlight blue.
Glucose and oxygen
5. What are the three products of cellular respiration? Highlight purple.
Carbon dioxide, water, and ATP
6. What things are recycled (used over and over again) during photosynthesis and respiration?
Carbon dioxide, water, oxygen and glucose
II. Apply (what you already know)
7. Sketch a model of typical plant cell and identify the mitochondria and chloroplasts.
8. What will happen to plants that are kept in the dark?
Plants will die since plants need daylight to deliver food. If there is no admittance to sunlight, the Light Dependent response will not happen.
9. What will happen if you forget to water your plants?
The plants will die since water is a necessary reactant photosynthesis.
10. What happens to animals that are deprived of oxygen?
Those animals will not be able to perform cellular respiration.
III. Big Ideas
11. One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
Obstructing the Sun would cause the powerlessness for essential makers, for example, plants, to go through photosynthesis, in this way not creating its own food fundamental for development and energy.
12. When you walk your dog, you are using energy from the sunlight to power this activity.
Explain. Sunlight gives the energy to essential makers to make their own food, using the carbon dioxide and delivering oxygen gas as a result of photosynthesis. The oxygen that is delivered into the environment is taken in by life forms as a reactant in respiration. Oxygen allows for ATP creation. The ATP is the substance energy structure that is needed to convey all cell processes such as walking your dog.
13. Carefully and completely answer the "essential question" of this activity. Use complete sentences and details from the model to explain your position.
Essential Question: What is the relationship between photosynthesis and respiration?
Photosynthesis and respiration are related since the reactants of photosynthesis are the products of cellular respiration, and vice versa. For example, the reactants of photosynthesis are energy, carbon dioxide, and water, while the products are oxygen and glucose. The reactants of cellular respiration are oxygen and glucose, while the products are energy, carbon dioxide, and water.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

How did the Mafia gain the interest and scrutiny of the public?
Mafia gain the interest and scrutiny of the public through their unique and fearful actions.
Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.
The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.

in an El nino event, surface temperatures of the pacific oceans are above average for at least a year. what effect, if any, would warmer temperatures have on the growth of a kelp forest ecosystem on the california coast?
El Niño is a phenomenon that impedes warm water to move westward and upwellings events. The kelp forest ecosystem is negatively affected by the rise in water temperature, lack of nutrients, and consequent effects.
-------------------------------
kelp forestThe kelp forest is a large population of brown algae that live in marine cool and relatively shallow waters rich in nutrients.
The population density is so high that they are considered to be marine forests, accomplishing many ecosystemic services, such as
absorbing CO₂, releasing a significant amount of O₂, protecting the coasts from waves erosion, and decreasing acidification.They are shelter and source of food for many different species, becoming one of the most diverse and productive habitats.
El Niño Event
The El Nino Southern Oscillation -ENSO- phenomenon occurs due to a complex system of climatic oscillations between the ocean and the atmosphere.
This phenomenon causes significant perturbations in the usual pluvial regimens in the tropics. It provokes
• dry seasons in areas where it usually rains
• rainy seasons in desertic regions.
ENSO phenomenon is dominant in the global climate system.
Under El Niño conditions
A tropical and weak stream in the Pacific acquires strength while the opposite streams debilitate. This change impedes warm water go westward, remaining on America's west coasts. Upwelling does not occur on the America's coasts. In some regions, temperatures rise, and unusual precipitations occur in desertic or dry areas -Atacama desert-. Other affected areas are Eastsouth Asia, Australia, and New Zealand, where there are fewer precipitations and cooler temperatures. Rainfall drops below the average, affecting crops and livestock. Effect of warmer temperatures on the kelp forest
The kelp forest is very sensitive to temperature changes. As a fact, the forest distribution depends on temperature as a limiting factor.
El Niño event has a damaging influence on these forests, not only because they reduce the availability of nutrients but also because they produce a significant change in water temperature.
Ocean warming negatively impacts algae reproduction, growth, and survivorship.
Algae are damaged by the temperature rise to the point of being eliminated.
Associated species composing the marine ecosystem are affected too since they have no refuge, food and live in environments with a higher concentration of CO₂, lower O₂, and more acidification.

In your own words, what is a trophic cascade?
Answer:
A trophic cascade is a side-effect when a trophic level (species) of the ecosystem is reduced or removed. Their ecological species interactions keep entire ecosystems balanced. Hence, suppressing their numbers or changing their behavior due to predation risk, results in an ecological imbalance or a trophic cascade.
Explanation:
BRAINLIEST PLEASE ;)Answer:
Tropic cascades in an eco-system is when a prey changes its behavior due to the predators attacks, thereby increasing in numbers indirectly for the survival of the predators.
