Answer:
Explanation:
Orcas customarily feed on sea lions and seals, which are packed with high-calorie blubber. But the population of Steller sea lions, the world's biggest sea lions, took a sharp dive in the late 1980s. Harbor seals also declined at a similar rate. By 1992, otters were the only plentiful marine mammals left in Aleutian waters. The orcas, in their hunt for calories, apparently had been forced to switch prey.

What is Mitochondria
Mitochondria was the powerhouse of the cell it contain oxidative enzymes that are needed for the stepwise oxydation of food by co2 and water. later on it converts the glucose into Atp and provide energy to body for doing activities
Hope it helps
Answer:
Mitochondria are like the power plants of the cell, similar to the engine of a car.
Mitochondria are organelles and they convert chemical energy (from food) into ATP, the main energy source for cellular work. Mitochondria suck and take in nutrients, break them down, and use it to make energy through the process of cellular respiration. One single cell has many mitochondria (1000 - 2000). This number really depends on the function of the cell.
For example, a nerve cell needs less energy than a muscle cell, and therefore will have fewer mitochondria. Kind of like a fast car needs a bigger engine than a slower car.
Also,
The mitochondria are closed in by two membranes. The outer membrane is the one that covers the organelle, and the inner membrane forms a special compartment with a fluid called the mitochondrial matrix. The inner membrane contains many folds called cristae, which increase the surface area inside the organelle. This increases the efficiency of the chemical reactions, allowing the mitochondria to create more ATP.

Which characteristic of life best describes the life cycle of a frog? having cells using energy responding to the environment growing and developing
Answer:
The correct answer is - growing and developing.
Explanation:
Al the given characteristics are the characteristics of a living organism including made up of cells, utilizing energy, response according to the environment, growth, and development, and others.
The life cycle of the frog can be described best by Growing and Developing as it grows from a tadpole to an adult frog by growing and developing. It is called metamorphosis which is an essential characteristic of frogs.
growing and developing.
All of the mentioned features are those of a living thing, such as the fact that it is made up of cells, that it uses energy, that it responds to the environment, that it grows and develops, and so on.Growing and Developing is the best way to define the frog's life cycle, since it grows from a tadpole to an adult frog by growing and developing.

The cytoplasm of a plant cell contains a 15% sugar solution. The plant cell is placed in sugar
solutions of different concentrations.
In which solution would there be a net diffusion of water out of the cell?
A5% sugar solution
B 10% sugar solution
с 15% sugar solution
D 20% sugar solution
Answer:
It's D!
Explanation:
cytoplasm contains a small ammoUNT OF sugar but it is higher than anyoe on the list here
20% sugar solution will cause a net diffusion of water out of the cell. Therefore option (D) is correct.
What is diffusion?Diffusion is the movement of a substance's individual molecules from a region of higher concentration to a region of lower concentration over a semipermeable barrier.
Simple diffusion and facilitated diffusion are the two primary subtypes that fall under the general term "diffusion."
Therefore, in the above question the concentration of water inside the cell is greater as compare to outside causing a net diffusion of water out of the cell to maintain the equilibrium.

All living things depend on water for survival. In an organism, what is water?
A. a tissue
B. a cell
C. a molecule
D. an organ
Answer:
A.tissue
Explanation:
Water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients
Consider plant roots and stems. Which tropism affects both these plant tissues? Which tissue experiences negative tropism versus which experiences positive tropisms?
The tropism experiences by both roots and stem tissue of a plant is geotropism.
Tropism is defined as the biological phenomenon in which the growth is affected with the response to stimuli.
Which tropism is found in both stem and root tissues?The tropism that affects the growth of plants are related to the gravity. The gravity force allows the roots to grow in the direction of gravity, and the stem grow in the direction opposite to the gravity.
The type of tropism found in the plants with respect to gravity is geotropism.
The roots are moving in the direction of the gravity, thus they experience positive geotropism. The stem moving in the opposite direction to gravity, thus it experiences negative geotropism.

1. What type of solution (isotonic, hypertonic, or hypotonic) do you think could have the greatest negative effect on transpiration and why?
Answer:
the hypertonic solution will have the greatest negative effect on transpiration
Explanation:
as the root hair cell of the plant in a hypertonic solution will loose water to the soil by osmosis (the net movement of water molecules from area of low water potential to area of high water potential down gradient)and as the hypertonic solution has low water potential(concentrated solution)so the water from the root (high water potential) will move out of the cell reducing the water intake so reducing the rate of transpiration .
The most detrimental effect on transpiration will be caused by the hypertonic solution.
Briefing:As the plant's root hair cell in a hypertonic solution loses water to the soil through osmosis (the net movement of water molecules from an area of low water potential to an area of high water potential down gradient), and as the hypertonic solution has low water potential (concentrated solution), the water from the root (high water potential) will move out of the cell, reducing the water intake and thereby slowing the rate of transpiration.
What is hypertonic and hypotonic in biology?A solution that has a lower solute concentration than solvent concentration is said to be hypotonic. On the other hand, a hypertonic has a high solute concentration in comparison to a solvent. a fluid that includes more dissolved particles, such as salt and other electrolytes, than blood and normal cells do. As instance, hypertonic solutions are being used to soak wounds.

Pregunta de ecología: ¿Cuáles factores ecológicos afectan a los ecosistemas acuaticos? - Describe cómo afecta cada uno de estos factores, a los ecosistemas acuáticos.
Answer:
Salinidad, acidez, oxígeno, niveles de luz y temperatura.
Explicación:
Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.
