Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.

CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?
2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?
4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)
Answer:
1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.
3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

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.

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.

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:-.

How much percentage of water does the human body have?
Answer:
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Explanation:
does this help please mark brainliest
■ About 60% - 70% of the human body is water.
■ This can vary from person to person though. ■ The average in females is 45% - 60% , while in males it's 50% - 60%.
■ Babies have more water content percentage (70% - 75%).

18-23 days
18-23 days
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.

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.
Sickle cell anemia is a monogenic disorder in which the body produces abnormally shaped red blood cells. Sickle cell anemia is inherited in an autosomal recessive pattern. A person who is a carrier for this disease typically do not show signs and symptoms of the condition. Two cousins in Bangladesh got married and had kids without being aware that sickle cell disease runs in their family. Laboratory testing later showed that both partners were carriers for the sickle cell mutation. If this couple decides to have children, What is the chance (probability) that their children will also be carriers of the sickle cell disease?
Answer:
there's a ½ or 50% chance of their children will also be carriers of the sickle cell disease.
Explanation:
let IA = normal and IS =sickle cell
since both parents are carriers so it would be IAIS x IAIS
