Answer:

Two plant groups you could look at are land-based plants and water-based plants.

Explanation:

Land-based plants:

Land-based plants are plants that can be found on land. They tend to be taller in order to absorb as much sunlight as possible. Land-based plants often have roots that are rooted in soil, and take in water and nutrients from there. Land-based plants taken in oxygen and carbon dioxide directly from the atmospheric air around them. In terms of the location of their stomata, stomata can be found on the underside of leaves, where they take in carbon dioxide and release oxygen.

Water-based plants:

Water-based plants can be found either submerged or floating on water. They tend to be broader instead of taller. For instance, their leaves will be broader in order to absorb maximum sunlight. This is because (especially for completely submerged water plants), light does not penetrate as deeply into water, leaving the plant with less light energy to photosynthesize. Water-based plants often have roots that either dig into the soil if they are found at the ocean floor, or hang freely in the water if they float on water surfaces. Unlike land-based plants, water plants, especially those that are fully submerged, take in dissolved carbon dioxide and oxygen gas in the water instead of from the air and atmosphere. The stomata of water-based plants are often found on the upper side of their leaves, in order to have better access to atmospheric oxygen and carbon dioxide.

You are working with an acute slice of mammalian hippocampus in a bath of artificial cerebrospinal fluid In your first experiment, you stimulate the mossy fiber projection with an extremely strong stimulus while patch clamp recording from the postsynaptic neuron. When the presynaptic axons are electrically stimulated, which of the following sequence of events occurs?

a. Opening of voltage gated calcium channels in CA1 neuron dendrites, release of glutamate containing vesicles into the synapse, potassium influx in CA3 neuron
b. Opening of voltage gated sodium channels in dentate gyrus axons, fusion of GABA containing vesicles with the presynaptic membrane, opening of GABA-gated ion channels, chloride influx into CA3 neurons
c. Opening of voltage gated calcium channels in CA3 neuron axons, fusion of glutamate containing vesicles to the presynaptic membrane, opening of voltage gated sodium channels in CA1 neuron dendrites, sodium influx into CA1 neurons
d. Opening of voltage gated calcium channels in dentate gyrus axons, fusion of glutamate containing vesicles to the presynaptic membrane, opening of AMPA receptors in CA3 neuron dendrites, sodium influx into CA3 neurons

Answers

Answer:

d. Opening of voltage gated calcium channels in dentate gyrus axons, fusion of glutamate containing vesicles to the presynaptic membrane, opening of AMPA receptors in CA3 neuron dendrites, sodium influx into CA3 neurons.

Explanation:

From the little information given above in the excerpts, it could be seen that, the sequence of events that would occur when the mossy fiber is stimulated with an extremely strong stimulus is what was given above.

Some students looked at pond water with a microscope. They saw prokaryotic and eukaryotic
organisms. The diagram shows one of the many organisms they saw.
Which best explains what type of organism this is? LT
(2 Points)

Answers

Answer:

C. Eukaryotic because it has a nucleus

Explanation:

All living organism have been classified into a wide category called DOMAIN, which consists of Eukarya, Prokarya, and Archaea. Living organisms are classified into each of these domains mostly based on whether or not they possess NUCLEUS in their cells.

Domain Eukarya known as Eukaryotes are made up of organisms that possess a membrane-bound NUCLEUS in their cell. According to this question, some students looked at pond water with a microscope and saw both prokaryotic and eukaryotic organisms. The organism displayed in the attached image is EUKARYOTIC simply because it has a NUCLEUS.

7. Pedialyte is a beverage which contains the same concentration of ions (K , Cl-, and Na ) as found in the plasma. Gatorade and Powerade mimic (although are not identical to) Pedialyte. Therefore, we might expect that consumption of Pedialyte should not significantly alter the osmolarity of the blood. How would you expect the urine production rate in the Pedialyte group to compare to that of the water group

Answers

Answer:

Less urine production.

Explanation:

The urine production rate in the Pedialyte group is lower as compare to that of the water group because the presence of K, Cl-, and Na ions. The precise combination of electrolytes and sugars in Pedialyte helps in restoring fluid levels and the nutrients in the body that are lost through sweating, urinating, or vomiting and diarrhea. We know that the presence of sodium ions regulation water and electrolyte balance in the body so there is less urine produced by taking Pedialyte group.

The urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.

The rate of urine output is the urine production in a unit of time. The normal range of urine output is 800 to 2,000 milliliters per day if you have a normal fluid intake of about 2 liters per day.

Drinking Pedialyte increases the ion concentration in the plasma that causes hyperosmolarity. This is sensed by the hypothalamus and releases ADH that leads to more fluid absorption in later DCT and collecting tubules that leads to decrease urine output. On the other hand, if you drink water, hypoosmolarity in blood plasma which does not sense by the hypothalamus and does not release ADH, and the urine output is more than the previous case.

Thus,

The urine production rate in the Pedialyte group to compare to that of the water group -

Pedialyte group - decreased

water group - increased.

Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. A mutation in Complex I decreases the efficiency of the electron transport chain. However, not all components of the electron transport chain are affected by this mutation. Which component of the electron transport chain will remain unaffected by a mutation in Complex I

Answers

Answer:

Complex II

Explanation:

The electron transport chain refers to a group of electron transporters embedded in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors which undergo redox (reduction and oxidation) reactions. The energy released during the transfer of electrons is coupled to the transfer of protons (H+) from the mitochondrial matrix into the intermembrane space, generating an electrochemical gradient that is then used to synthesize ATP. Complex I and Complex II are membrane-bound complexes that act as mitochondrial redox carriers. Complex I is a proton pump that uses energy from the electron transfer chain to pump protons, while Complex II sends H+ onto Complex III in the form of the reduced ubiquinol. Complex I receives electrons from NADH and transfers them to ubiquinone, while Complex II directly receives the redox cofactor FADH2 that does not pass through Complex I.
