Answers
Answer:
The non-coding regions of DNA are called introns. They are significant in evolution since they offer a great 'recipe' for recombination with genes/exons. Therefore, this offers variations among individuals on which natural selection could act upon to help a population adapt to changes in the environment. Introns also offer an additional step in gene regulation through the splicing of introns in making of mRNA.

Why did you not see any chloroplasts in the onion epidermal cells, unlike in the Elodea (Anacharis) cells?
-Chloroplasts in onion cells are hidden by the large central vacuole.
-The part of the onion viewed under the microscope grows underground.
-The purpose of chloroplasts is to make the plant green but onions are not green.
-Chloroplasts are organelles that absorb sunlight energy and perform photosynthesis.
-Plant parts that grow underground are not exposed to sunlight.
-Onions had chloroplasts before they were picked from the ground but the chloroplasts dried up and disappeared after being exposed to the sunlight.
-Onions are not plants and therefore do not have chloroplasts.
-Plant parts that are not exposed to sunlight cannot do photosynthesis.

Answers
Brief Overview of Characteristics of Four Eukaryotic Kingdoms:
1. Protista = either unicellular or multicellular organisms that may either be able to produce their own food or eat other smaller organisms.
2. Fungi = mostly multicellular organisms characterized by the presence of filaments called hyphae (sing. hypha). It cannot produce its own food, thus, it is usually parasitic on another organism.
3. Animalia = multicellular organisms that may have the presence or absence of a spinal column and it cannot produce their own food. It eats either plants or other animals.
4. Plantae = mostly multicellular organisms that can produce their own food through photosynthesis and characterize by the presence or absence of the vascular tissues: xylem and phloem.
ANSWER:
1. PROTISTA = plant-like or animal-like, autotrophs and heterotrophs
2. FUNGI = unicellular & multicellular heterotrophs
3. ANIMALIA = vertebrates and invertebrates, multicellular heterotrophs
4. PLANTAE = vascular and non-vascular, autotrophs

(2) 999.0 mb
(4)
1004.0 mb
Answers
According to the Earth Science Reference Tables, an air pressure of 29.65 inches of mercury is equal to (2) 999.0 mb.
Air pressure is commonly measured in inches of mercury (inHg) or millibars (mb). The conversion between these two units can be found in the Earth Science Reference Tables.
In this case, the value of 29.65 inches of mercury corresponds to 999.0 millibars (mb). This conversion factor allows scientists and meteorologists to compare and express air pressure measurements using different units.
Millibars (mb) are a unit of pressure commonly used in weather forecasting and meteorology. It represents the force exerted by the atmosphere over a given area.
Inches of mercury (inHg), on the other hand, are more commonly used in some countries, particularly in the United States. The Earth Science Reference Tables provide conversion factors to facilitate the interchange of these units.
Therefore, an air pressure of 29.65 inches of mercury is equal to 999.0 millibars (mb) according to the Earth Science Reference Tables.

The correct answer is - option C.
Explanation:
Anton Leeuwenhoek observed the presence of organisms in his tooth scratch or scrapings under the primitive microscope made by himself. At that time there was no knowledge about the bacteria and he named these small creatures as animalcules. These animalcules were bacteria actually.
These creatures were single-cell organisms and able to perform the function as an entity and postulate that bacteria is a single which is a fundamental unit of function and structure of all living organisms.
Conjecture what would happen if a primate infant did not possess your chosen primate hand features. Answer this question with the survivability of the infant in mind
Answers
Answer:
Where the primate infant did not possess primate hand features, it will not be able to feed itself. For example, a monkey cannot survive without its grasping hands. It uses them to feed itself. So if an infant monkey does not possess the primate hand features, its survival will be greatly hampered.
Explanation:
Ordinarily, primates (including humans) have five fingers on each of their hands and five toes on their feet. Most primate species have fingernails instead of claws, and they have touch-sensitive pads on each of their digits. The hands and feet of all primates are designed for grasping, with the only exceptions being humans. Human beings feature deep perceptions that differentiate them from other primates.
Look at the figures showing the distribution of volcanoes and earthquakes. Why do volcanoes and earthquakes occur in so many of the same areas?
Volcano Distribution
Earthquake Distribution
Answers
Volcanoes and earthquakes occur in so many of the same areas because they are a consequence of plates movements. They occur at different plate boundaries.
Image observationFirst of all, by looking at both images, we can see that volcanoes and earthquakes are not randomly distributed around the world.
We can also see that, although they are distributed all around the globe, there is a notorious concentration of volcanoes and earthquakes in the pacific region.
There is an occurrence tendency in continuous areas.
If we pay attention to the white lines in the map, we will notice that the continuous areas where volcanoes and earthquakes occur coincide with plate boundaries.
For instance,
In North and South America plates, volcanoes and earthquakes occur along the Pacific Plate and the Nazca plate boundaries. We can see the same pattern in the boundaries between the Pacific plate, Indo-Australian plate, Eurasian plate, and Philippine plate. We can also see some volcanoes and earthquakes occurring along the Atlantic mid-oceanic ridge. Finally, we can see only earthquakes occurring along the boundary of the Antarctic plate with the other plates.InterpretationAlthough they occur in other areas too, volcanoes and earthquakes occur at plate boundaries.
Volcanoes occur at convergent and divergent boundaries
Earthquakes occur at transforming, convergent and divergent boundaries.
Plate BoundariesI. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.The hot material creates a new seabed between the separating plates, expanding the sea bottom.Eruptions do not produce big notorious mountainous volcanoes due to the temperature shock between the rising hot magma and oceanic water.The Atlantic Ocean ridge, extending from Greenlander to the southernmost point of South America, is an example of this boundary.Plates movement might produce earthquakes.II. Convergent.
Collision area between two plates.Two oceanic plates might collide, or one oceanic plate with a continental one.One plate sinks under the other plate, and magma rises to the surface by crevices.The thicker and older plate subduces under the other plate.Volcanoes get formed on the superior plate since magma flows over it.Plates's movement might produce earthquakes.III. Transforming.
The plates slide laterally with each other, and they are usually called faults. It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate. No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.In coclusion, volcanoes and earthquakes distribution coincides with plate's boundaries.

The region in the ocean where marine creatures are capable to do photosynthesis is the photic area, part of the photic area is in the neritic portion where is found the litoral and the sublittoral, being the sublittoral next to the epipelagic and pelagic zones. Therefore, between the alternatives the one that talks about a region where photosynthetic organisms are found is sublittoral, that's because less light to none can be available in deeper regions of the ocean, and the abyssal layer is the last in the model of ocean distribution layers.
