Answer:

The answer is spongy mesophyll.

Explanation:

Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.

Drag each label into the proper position to identify whether the indicated structure is located on the femur, humerus, or both.
Evgen [1.6K]

Femur: Greater trochanter-Gluteal tuberosity. Humerus: Coronoid fossa-Intertubercular sulcus-Trochlea-Lesser tubercle-Deltoid tuberosity-Olecranon fossa. Both, femur and humerus: Medial epicondyle-Capitulum-Intercondylar fossa-Lateral epicondyle-Head.  

Further Explanation:

Femurs:  

femurs or femora, or thigh bone, is the proximal bone of the hindlimb in tetrapod vertebrates. The head of thefemur explains with the hip bone socket in the pelvic bone framing the hip joint, while the distal piece of the femurarticulates with the tibia and kneecap shaping the knee joint.  

Humerus:  

The humerus is the long bone in the upper arm. It is situated between the elbow joint and the shoulder. At the elbow, it associates essentially to the ulna, as the lower arm's outspread bone interfaces with the wrist. At the shoulder, the humerus associates with the edge of the body by means of the glenoid fossa of the scapula.  

Femur or humerus:  

Humerus is situated in the upper arm, while femur is found in the upper leg. The length and the normal breadth of the femur are higher than that of humerus.Femur is the biggest bone in the body while humerus is the second biggest. Femur is more grounded than humerus.  

humerus and the femur comparative:

The humerus and the femur are relating bones of the arms and legs, separately. While their parts are comparable by and large, their structure has been adjusted to contrasting capacities. The leader of the humerus is practically hemispherical, while that of the femur shapes around 66% of a circle.

Mariana [72]

Answer:

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

Explanation:

Below is the full question:

Theodor W. Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light.

What did Engelmann conclude about the congregation of bacteria in the red and blue areas?

A) Bacteria released excess carbon dioxide in these areas.

B) Bacteria congregated in these areas due to an increase in the temperature of the red and blue light.

C) Bacteria congregated in these areas because these areas had the most oxygen being released.

D) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.

E) Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis.

The most efficient region of white light for photosynthesis has been found to be the blue and red region of the white light. Hence, these two regions must have had the most oxygen being released because they are the regions with the highest rates of photosynthesis.

<em>Aerobic bacteria thrived better in the regions illuminated by red and blue light because these regions had the highest oxygen production as a result of having the highest rates of photosynthesis.</em>

<em>The correct option is C.</em>

Which of the following best describes the mechanism by which steroid hormones control gene expression? View Available Hint(s) Wh
Veseljchak [2.6K]

Answer:

Steroid hormones that enter the cell activate receptors. These hormone-receptor complexes then bind HREs and influence gene expression.

Explanation:

Mechanism of action of steroid hormones is as follows:

  • Steroid hormone enters cell and bind to the receptor.
  • Translocation of activated receptor- ligand complex into nucleus.
  • This complex then bind to another receptor on the chromatin.
  • Steroid receptors form dimers.
  • Act on DNA
  • These hormone-receptor complexes then bind HREs and influence gene expression.
  • Augmentation or Suppression of transcription.

A person eats a large pasta meal at lunch and then goes for a run before dinner. Explain how the body taps energy from this star
Ilia_Sergeevich [38]

Starches help give you an extra boost of energy during your workout. Starches, as well as sugars, eventually break down into glucose -- your body's main fuel source.

Explanation:

When you eat starchy foods, you'll have a supported energy level over a period of numerous hours. This is separate from sugars, which are simple polysaccharides that give you a quick surge of energy but do blank to keep your energy levels running.
