Answer:
Yes, dynamic equilibrium is present in the cell.
Explanation:
In dynamic equilibrium, the concentration of solute remain the same due to equal flowing of solutes inside and outside the cell so there is no change occurs inside the cell, the cell maintain same concentration of solutes both inside and outside the cell. Dynamic equilibrium is a type of equilibrium in which the reactants and products formed at the same rate and no change occurs inside the reaction. In the cell, homeostasis is responsible for maintaining equilibrium in the cell so no change occurs inside the cell.

Looking at the following organisms and their diets, place them into a food chain. Make sure you have arrows that show the correct flow of energy.
Aardvark: omnivore diet
Ant: herbivore diet
Grass: autotroph
Hyena: carnivore diet
Answer:
Grass > Ant > Aardvark > Hyena
Explanation:
The grass is autotrophic, which means it can produce its own food It does so using water, carbon dioxide, and light energy from the sun. The organisms in this food chain rely on other organisms for food.
The ant is a herbivore that consumes the grass for energy. The aardvark consumes both plants and animals (omnivore), so it can consume the ants. The hyena is a carnivore, meaning it only eats animals, such as the aardvark.

Which biome has low nutrient quality soil?
coniferous forest
tropical forest
deciduous forest
boreal forest
Answer:
Tropical
Explanation:
The high temperature and moisture of tropical rainforests cause dead organic matter in the soil to decompose more quickly than in other climates, thus releasing and losing its nutrients rapidly. The high volume of rain in tropical rainforests washes nutrients out of the soil more quickly than in other climates.
Answer:
it boreal forest also known as tiaga
Explanation:
The northern Eurasian coniferous forest is called the taiga or the boreal forest. Both terms are used to describe the entire circumpolar coniferous forest with its many lakes, bogs, and rivers. Coniferous forests also cover mountains in many parts of the world.

place the following molecules in the order smallest to biggest
Answer:
NH₂⁻<NH₃<NH₄⁺
Explanation:
Hello.
In this case, regarding the molecules:
NH₄⁺, NH₃ and NH₂⁻.
Which are ammonium, ammonia and amide, in order to rank them in terms of how big the angles are, we need their molecular geometry as shown on the attached picture. As you can see, the geometry of ammonium is tetrahedral with an angle between H bonds of 109.5°, the geometry of ammonia is trigonal pyramidal with an angle between H bonds of about 107° and the geometry of amide is bent with angles of 104.5°.
Therefore the order from smallest to biggest is: NH₂⁻<NH₃<NH₄⁺.

Which cell specimen is a prokaryote?
A Cell 1
B Cell 2
C Cell 3
Answer:
Cell 3
Explanation:
One of the unique main characteristics that differentiates a prokaryote from a eukaryote is the absence of presence of nucleus in their cell, and where their DNA is found.
In prokaryotic cells, nucleus is absence. The DNA of prokaryote is not found in a nucleus, rather, it is contained in a region referred to as nucleoid.
Therefore, the specimen that does not have DNA in nucleus is definitely a prokaryote.
Cell 3 is a prokaryote.

A student uses a telescope to view stars at night. The student notices some of the stars are different colors. The color of a star is determined MOST by its
Select one:
a. size.
b. distance from Earth.
c. mass.
d. temperature.
The color of a star is determined most by its mass. Thus, option C is correct.
On which factor brightness of the star depends?The brighter the star is, the closer it will be from the Earth. Hence, the brightness of a star depends upon the distance between the star and the Earth. The color of a star tells you how cool or hot it is. Blue colored stars are cool while red colored stars are hot (like sun).
A star is a celestial object that produces light and heat through nuclear fusion reactions in its core. Stars are made up of hot, dense gas and have their own gravity, which helps them maintain their shape. They are classified based on their temperature, size, and luminosity.
Most stars are part of a galaxy and are found in clusters called star systems. The sun is a star and is the closest star to Earth. Stars play a crucial role in the evolution of the universe and are essential for the formation and survival of planets, including Earth.
Therefore, The color of a star is determined most by its mass. Thus, option C is correct.

You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying out this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
1.Compare the hibiscus and spider lily pollen grain structure.
2.Why stigma at the top of the pistil is often sticky?
3.Why pollen is important in fertilization?
Answer:
Explanation:
Hibiscus flowers attract pollinators with their bright colors and a bull's-eye pattern leading to a deep throat. The deep throat and prominent stamen and stigma mean pollinators need to bump the stigma to probe deeper in the flower. Pollen sticks to the pollinator and is transferred to the female parts of either the same flower or sometimes a different flower. Pollinators are rewarded for their pollination efforts by by being allowed to consume the surplus pollen the flowers produce.not sure about spider lily
answer for 2 The top part of the pistil is called the stigma and is sticky so it will trap and hold pollen. In flowering plants, the flower functions in sexual reproduction.
answer for 3 The ultimate function of pollen is to deliver male gametes (sperm) from the stamen of a plant to an ovule for fertilization of an egg, which then develops into a seed

B. friction between the plate and the asthenosphere and pressure of magma on the
edge of the plate
C. gravity acting on the edges of plates and convection in the mantle
D. convection in the mantle and pressure of magma on the edge of the plate
Answer:
C. gravity acting on the edges of plates and convection in the mantle
Explanation:
A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Therefore, the option (C) is correct.
What are lithospheric plates?Plate tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
Earth's crust, called the lithosphere, consists of 15 to 20 moving tectonic plates. The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another.
In plate tectonics, Earth's outermost layer, or lithosphere—made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
