Answer:
The correct option is A) mesosphere only
Explanation:
The solar radiation is not absorbed by the mesosphere of the Earth. Hence, the temperature of the mesosphere decreases as the altitude increases. At the mesopause, the temperature begins to increase with altitude, and this trend continues in the thermosphere.
On the other hand, in the stratosphere, temperature increases with altitude. Hence, other options are not correct.

Describe an example of an octopus learning
Answer: Octopuses and their kin (cuttlefish and squid) stand apart from other invertebrates, having evolved with much larger nervous systems and greater cognitive complexity.
The majority of neurons in an octopus are found in the arms, which can independently taste and touch and also control basic motions without input from the brain.
Octopus brains and vertebrate brains have no common anatomy but support a variety of similar features, including forms of short- and long-term memory, versions of sleep, and the capacities to recognize individual people and explore objects through play.

Which of the following describes asexual reproduction?
fertile offspring despite geographic isolation
one parent organism and no egg or sperm
two parent organisms and genetic exchange
infertile offspring through genetic exchange
Answer: One parent organism and no egg or sperm.
Explanation: Asexual reproduction only needs one parent, and they don't need sex cells.
Explanation:
Asexual reproduction is when single-parent give rise to several offspring, without the fusion of gametes.
One parent organism and no egg or sperm: Asexual reproduction takes place in simple organisms, and these organisms are not able to develop sex cells (egg or sperm).
In asexual reproduction single parent organism divide to produce several offspring and they are genetically identical to their parents as they reproduce without the involvement of another organism.
Hope it Helps!Why are oil coal and natural gas not found them evenly distributed on earth?
The amount of oil, coal, and natural gas reserves on Earth is not distributed evenly because the amount of plants and animals buried earlier in sedimentary rock layers determined the amount of oil and gas reserves.
What is the importance of oil and coal?Oil and coal are fossil fuels that are vital to today's society, and they are formed when heat and pressure cause these remains to be transformed into hydrocarbons, which are the main components of oil and natural gas. These sedimentary rock layers are found in areas that were once covered by oceans or seas, such as coastal regions and deltas, and after many years, they become fossil fuels.
As a result, the amount of oil, coal, and natural gas reserves on Earth is not distributed evenly because the amount of plants and animals buried earlier in sedimentary rock layers determined the amount of oil and gas reserves.

Final answer:
Oil, coal, and natural gas are unevenly distributed because their formation required specific geological conditions that are only found in certain areas. Fossil fuels take millions of years to form and are being depleted much faster than they are replenished, leading to varying degrees of scarcity across different regions of the world.
Explanation:
The uneven distribution of oil, coal, and natural gas on Earth is due to a complex set of geological processes. Fossil fuels are the remains of ancient organisms that were subjected to intense heat and pressure over millions of years. For oil to form, there needs to be just the right biological conditions to produce sufficient plankton, coupled with the correct geologic conditions to preserve and transform this organic matter into petroleum. This process takes a million years or more.
Coal is relatively more abundant and formed from ancient swamp vegetation, while oil and natural gas originated from marine microorganisms. Oil deposits are frequently found in ancient shallow seabeds where organic material was effectively sequestered and transformed over time. Regions like the province of Alberta in Canada are rich in these resources due to their geological history and current explorations are focused on extracting these fuels from tar sands and other reserves.
The extraction and use of these fuels vary; coal is mined and used primarily for electricity generation due to its solid state, while oil and natural gas require different extraction methods, including conventional drilling and hydraulic fracturing. Moreover, due to the accelerated rate of consumption compared to the natural replenishment rate of these resources, they are not only unevenly distributed but also rapidly depleting, underscoring the need for conservation and alternative energy sources.

Answer: True
Explanation:
Over past decades the scientists have found evidence that indicates that the increase in the change of climate may lead to an increase in the frequency and intensity of the events. This may contribute to the events like extreme heat, rainfall and can even lead to disastrous events like hurricanes.
For other events like tornadoes, drought periods the evidences like little or no rain have been found.
The scientists have also found that the change in the global average temperature is because of human influence. Climatic attribution has been developed so that the scientists can identify and quantify that can measure the human-caused climatic changes resulting in the extreme weather.
How many genes influence a polygenetic trait?
A: one gene
B: more than one gene
C: zero genes, just the environment
D: one gene with multiple alleles
Answer: B: more than one gene
Explanation: A polygenic trait is a trait that is influenced by more than one gene. Every trait is controlled by at least one pair of gene. When a trait is controlled by one gene, it is called a monogenic trait but when a trait is controlled by more than one gene, it is called a polygenic trait. Polygenic traits do not obey mendelian pattern of inheritance and they involve the interaction of multiple genes. Examples of polygenic traits in humans are hair colour, eye colour, skin colour.

predict what happens when a cell is placed in a solution with an equal concentration of water outside the cell and inside the cell.
Answer: Nothing will happen.
Explanation: When a cell is placed in a solution with an equal concentration of water outside the cell and inside the cell, there will be no movement of water molecules across the cell membrane. There will be no osmosis because the solution inside the cell and the solution outside the cell are isotonic, this means that they have equal concentration. The two solutions are in equilibrium, therefore there will be no movement of water molecules across the cell membrane. For osmosis to occur there must be different between the water concentration in the two environments.

describe the location of the blueprint that determine the structure of each of these forelimbs as the organism develops from embryo to infant
Answer:
The DNA in the nucleus.
Explanation:
The blueprint that contains all of the instructions to "build" and maintain an organism is found in the DNA.
The DNA is the hereditary molecule found in the cell nucleus. The sequence of the DNA determines the expression of genes, which make proteins in the cell. Proteins carry out essentially every function in the cell, including dictating the development of forelimbs.
Therefore, all the information required for the organism to develop is encoded in the DNA.
The location of the blueprint that determines the structure of forelimbs as an organism develops from an embryo to an infant is found in the genetic material within the cells.
These blueprints are known as the homeobox (Hox) genes, which are a group of related genes that control the body plan of an embryo.
During embryonic development, the Hox genes are expressed in a specific spatial and temporal pattern that dictates the identity and position of the developing limbs along the anterior-posterior axis. The Hox genes are located in clusters on particular chromosomes, and each gene in the cluster corresponds to a specific region of the body.
In vertebrates, the forelimbs develop from the lateral plate mesoderm, which forms the limb buds. The Hox genes, along with other signaling molecules such as Sonic hedgehog (Shh), Fibroblast Growth Factors (FGFs), and Bone Morphogenetic Proteins (BMPs), regulate the proliferation, differentiation, and patterning of cells within the limb buds to form the structures of the forelimbs, such as the humerus, radius, ulna, carpals, metacarpals, and phalanges.
The precise regulation of these genes and signaling pathways is crucial for the proper development of the forelimbs. Any disruption in the expression or function of these genes can lead to developmental anomalies or limb malformations.
In summary, the blueprint for the structure of forelimbs is encoded in the Hox genes, which are part of the organism's genome. These genes interact with various signaling pathways during embryonic development to direct the formation of the limbs, ensuring that the correct structures develop in the appropriate locations.

Muscarinic
28. Sympathetic effector "synapse"
Nicotinic
Neuromuscular junction - Nicotinic
Parasympathetic effector synapse - Muscuranic
Sympathetic effector "synapse" - Adrenergic
Explanation:
Neurotransmitters transmit the electric signal from the neuron to another neuron or an effector cell which is the target cell like the muscles or the glands. Receptors are transducers which connect with the external and internal environment and carry the nerve signals.
The neuromuscular junction refers to the synaptic connection between a nerve cell and a muscle cell. The primary receptor at the neuromuscular junction is the nicotinic acetylcholine receptors which respond to acetylcholine neurotransmitters.
The parasympathetic nervous system works with muscuranic receptors which are activated by acetylcholine. These receptors transducts the neurosignals (chlorinergic) in the parasympathetic end organs.
The sympathetic nervous system is associated with the adrenergic receptors and activated by epinephrine or norephinephrine and controls blood flow in the vessels.

Which structural adaptation most likely helps the meerkats survive in their habitats
A.) Meerkats have flexible necks, so they can reach tree leaves for food.
B.) Meerkats have sticky tongues, so they can catch insects to eat.
C.) Meerkats have sharp claws and powerful front legs, so they can dig to get cool.
D.) Meerkats have long, curly tails, so they can climb tall trees
Answer:
i am pretty sure its C
Explanation:
Meerkats are specially adapted to living in the harsh desert environment. Dark patches around their eyes help them be effective lookouts by reducing the glare of the sun, much like a baseball player who paints dark lines beneath his eyes. Their eyes also allow them to take in a wide angle view of the scene. This helps prevent predators from gaining an advantage by sneaking up.
Meerkats also possess special adaptations to help them burrow. Their eyes have a clear protective membrane that shields them from dirt while digging. Their ears also close tightly to keep dirt out.
These are just some fact for them where it says that they dig so probbably it is C.
