Answer:
D at this time of year the sun will reach its highest elevation in the sky for the NH sites
Explanation:
when you press play on the starry night simulator the earth rotates and you will see that most of the sun is in the northern Hemisphere so I guessed and it was correct.
Imagine two species of snakes that live in a tropical rain forest of Malaysia do not typically interbreed. In nature, one species is ground-dwelling and feeds mainly on insects and small amphibians near water, whereas the other snake feeds in the lower to mid-canopy of trees and vines rising from the forest floor. However, at a zoo in Singapore where they were kept in the same gallery exhibit, the two species were observed interbreeding and produced viable offspring. Which of the following reproductive barriers is most likely preventing these species from interbreeding in the forest?
a. habitat isolation
b. gametic isolation
c. reduced hybrid viability
d. a postzygotic barrier
e. mechanical isolation
Answer:
a. habitat isolation
Explanation:
Habitat isolation is a type of prezygotic reproductive barrier caused by differential habitat preferences, thereby lowering the probabilities of mating between individuals living in different habitats. Habitat isolation is a mechanism of ecological speciation that over time leads to divergence of populations and reproductive isolation. In habitat isolation, different species or populations that could interbreed with one another to produce offspring are prevented from mating as a consequence to be isolated by habitat barriers. In India, for example, lions and tigers can mate to produce offspring; however, they don't interbreed due to habitat barriers (tigers are found primarily in rainforests and lions inhabit the grasslands).
PLEASE? it does have to be very long... Describe why the new organism created during sexual reproduction is not an exact copy of the parent(s)?
because of its history/ancestry it has lines from them so the looks look differant and so are some of the genes. Hope this helps

On a given microscope, the numerical apertures of the condenser and low power objective lenses are 1.25 and 0.25 respectively. You are supplied with a filter that selects a wavelength of 520 nm.
a. What is the limit of resolution of this microscope?
b. Will you be able to distinguish 2 points that are 300nm apart as being separate, or will they blur into one?
Answer:
a. Resolving power (R) = 346.7 nanometers (nm)
b. No, because the resolving power is 346.7 nm
Explanation:
In microscopy, resolution or resolving power (R) refers to the minimum distance at which two distinct points can still be distinguished as separate entities. R can be calculated by the following equation:
Resolving power (R) = wavelength /(NAo + NAc), where NAo is the numerical aperture of the objective and NAc is the numerical aperture of the condenser. In the case above described:
R = 520 nanometers / (1.25 + 0.25) = 346.7 nanometers (nm)
In consequence, the resolving power of this microscope at 520 nanometers of wavelength is 346.7 nm, thereby two points separated by 300 nm will be too close to be distinguished as separated objects.

Look at the organisms below. What do these organisms have in common?
1.skeletal structure
2.constant body temperature
3.presence of spinal cord
4.pattern of symmetry
Answer:
D. Pattern of symmetry
Explanation:
The bird, insect and the giraffe all have the same pattern of symmetry or body plan.
They have bilateral symmetry. This is because of a vertical plane is run through each of them, from top to bottom, the body parts would be divided into two. That is each side would have equal arrangement of the different parts that makes up the organism. This is why it is referred to as bilateral symmetry.

The illustration represents particles moving through a cell membrane. What image represents active transport?
Answer:
According to the illustration of transmembrane transport mechanisms, the one representing an active transport mechanism is labeled with the letter C.
Explanation:
The semipermeable nature of the cell membrane causes the passage of necessary substances from the cell to pass through various transmembrane transport mechanisms.
In the illustration, active transport is labeled with the letter C, which can be stated because:
The passage of particles is against the concentration gradient. It requires energy to take place.The type of transport in the illustration corresponds to primary active transport.
Answer:
C.
Explanation:
transmembrane transport mechanisms.
What happens during the calvin cycle? how does the calvin cycle depend on the light reactions?
Answer:
-The ATP provides the energy, and the NADPH supplies the electrons for the Calvin cycle, which converts carbon dioxide to sugar. The ADP and NADP+ that result from the Calvin cycle shuttle back to the light reactions, which regenerate ATP and NADPH.
Explanation:
What do matter and energy have in common?
Answer:
Explanation:
Energy and matter characterize both physical and biological systems. These systems are defined both by the types of energy and matter they contain and by how that matter and energy move through and between systems. In natural systems, both energy and matter are conserved within a system.

Explanation:
Cholesterol helps maintain the rigidness of the _____
membrane because it's an amphipathic molecule.
Answer:
Why a bilayer?
What's on the inside of the cell and on the outside? Mostly water. As you can see here, the water-based interior of the cell has lots of components. These need to be kept inside the cell. And it is the nature of the phospholipid bilayer to keep the inside of the cell separate from the outside.
Explanation:
Cholesterol helps in maintaining the rigidness of the cell membrane.
• The plasma membrane of the cell is a fluid combination of cholesterol, phospholipids, and proteins. The cholesterol helps in maintaining the membrane of the cell firm and stability over a different range of temperatures.
• Cholesterol is an amphipathic molecule, which comprises a tetracyclic ring composition and holds a trans conformation. This helps the molecule to exhibit a rigid and planar feature that enhances the packing of the membrane, and also contributes to the rigidity and integrity of the cell membranes.
Thus, the given blank can be filled with cell.
