This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for Seafloor spreading.

What is seafloor spreading?

Seafloor spreading is the hypothesis that the ocean's crust develops along the mid-ocean ridge system's undersea mountain zones and spreads out laterally away from them. The theory of plate tectonics, which revolutionised geologic thought throughout the final quarter of the 20th century, was developed in large part as a result of this concept.

When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection. Mantle convection is the term for the mantle's slow, turbulent circulation.

Hence the correct option is B; seafloor spreading.

Answer:

The industrial use of water for hydraulic fracturing, or fracking, can have a significant impact on the availability and quality of water resources. Fracking requires large volumes of water to be mixed with chemicals and injected underground to extract oil and gas from shale formations. This high demand for water can strain local water supplies, especially in regions already facing water scarcity or drought conditions. Moreover, the water used in fracking becomes contaminated with various chemicals and pollutants, making it challenging to treat and potentially affecting the quality of nearby water sources through leakage or spills. The potential depletion and contamination of water resources due to fracking underscore the importance of careful management and regulation to ensure the sustainable use and protection of water supplies.

Bacteria are classified into five groups according to their basic shapes:

1.spherical shape (cocci) :

e.g Staphylococcus aureus grows best in an aerobic environment but it can also live in anaerobic conditions (without oxygen).

2.rod shape (bacilli):

3. spiral (spirilla) :

4.comma (vibrios) or corkscrew (spirochaetes):

They can exist as single cells, in pairs, chains or clusters.

Microorganisms can be classified according to their oxygen requirements necessary for growth and survival:

Obligate Aerobes: (oxygen required)

Facultative: (grow in the presence or absence of oxygen)

Microaerophilic: (grow best at very low levels of oxygen)

Aerotolerant Anaerobes: (oxygen not required for growth but not harmful if present)

Obligate Anaerobes: ( grow only in complete absence of oxygen; if present it can be lethal)

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.

Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.

Describe three different strategies used by three different animals to thermoregulate.

If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?

If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.

Answer:

1. central

2. action potential

3. nerve net

4. dorsal

5. hydrostatic

6. Exoskeletons

7. contraction/contracting

8. Fertilization

9. external fertilization

10. Eggs

11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.

12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

The correct order of the steps in recognizing a smell is:

1. Olfactory receptors detect vaporized odor molecules

2. Neurons are stimulated

3. Nerve impulse travels to the olfactory bulb in the brain

4. Signal forwarded to the cerebral cortex for interpretation

This neural code originates from sensory neurons in the nose. When an odorant molecule binds to a receptor it initiates an electrical signal that travels from sensory neurons to the olfactory bulb. The olfactory bulb is a structure at the base of the forebrain that relays signals to other brain regions for further processing.

Olfactory receptors are located in the olfactory epithelium. This is a specialized area of ​​the nasal mucosa that covers part of the ethmoid bone in the upper nasal cavity. The reticular formation controls the level of consciousness, the cardiovascular system, and the respiratory system. The ascending sensory system passes through the brainstem on its way to the thalamus.

Explanation:

However, we discover that loss of chromosome alignment results in aberrant chromosomal organization, interchromosomal compaction problems during anaphase .

The end of mitosis is signaled by the telophase, or the stage in which the chromosomes reach their poles. As the nuclear membrane heals, the chromosomes begin to decondense into their interphase conformations. Cytokinesis, or the division of the cytoplasm into two daughter cells, occurs after telophase.

During meiosis I, sister chromatids—or homologous chromosomes—split during anaphase and move to the opposite poles of the cell with the help of microtubules. The homologous or sister chromatids are drawn to one pole of the cell when nondisjunction takes place since there is no separation.

Activation of glucose-6-phosphate dehydrogenase, hexokinase, glucose-6-phosphatase and glucokinase would indirectly affect the reaction direction of phosphoglucomutase.

All the option are corect. B

An enzyme called phosphoglucomutase moves a phosphate group from the 1 to the 6 position on a -D-glucose monomer in the forward direction or from the 6 to the 1 position in the reverse direction.

A compound made of inorganic vanadate and alpha-D-glucose 1-phosphate (Glc-1-P) inhibits phosphoglucomutase (Vi). The concentrations of Glc-1-P and Vi affect both the inhibition at steady state and the pace of approach to steady state.

In order to raise the levels of cyclic Adenosine monophosphate (cAMP), which activates PKA, glucagon promotes adenylyl cyclase activity. To convert glycogen to glucose 1-phosphate, PKA increases glycogen phosphorylase activity. Phosphoglucomutase isomerizes glucose 1-phosphate to G-6-P.
