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.

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.

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.
Hope this helped!

Which group has the smallest dispersal distances *
1 point
a) Seaweeds
b) Fish
c) Crabs
d) Marine Snails
Answer:
d) Marine Snails
Explanation:
Marine Snails has the smallest dispersal distance because of their slow mobility. These marine snails have very limited mobility when they are adults and spend their majority of lifetimes in a small geographical area. Dispersal distance refers to the distance a species can move from an existing place or population or the parent organism. According to this definition we can say that marine snails have the smallest dispersal distances.

necesito un impacto negativo de la biodiversidad del mosquito aedeomyia squamiennis
ayuda:/
Answer:
El cambio climático tiene un impacto negativo.
Explicación:
El impacto negativo en la biodiversidad del mosquito aedeomyia squamiennis se debe al cambio climático que disminuye su población porque el cambio climático hace que el medio ambiente sea desfavorable para el mosquito. Debido a este cambio climático, aquellos organismos que se adoptan de acuerdo con el cambio ambiental pueden sobrevivir pero aquellos que no pueden extinguirse del medio ambiente, por lo que podemos decir que el cambio climático tiene un efecto negativo en la biodiversidad del mosquito aedeomyia squamiennis.

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.

What is mitosis?
Mitosis definition is the division of the mother cell into two daughter cells genetically identical to each other.
✨
Why is it important?
Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creating two identical copies, referred to as daughter cells.
