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.
A nuclear membrane forms around the chromatids that came from different chromosomes
Answer:
False
Explanation:
They are identical. It happens during the anaphase. Then during telephase a nuclear membrane will form around each set of chromosomes to separate the nuclear DNA from the cytoplasm.

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.

The image below shows a group of meerkats. Meerkats live in habitats that are very dry, hot, and sandy.
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.
Janet is studying a population of genetically-identical individuals. Janet can conclude that these organisms ____?
A. do not reproduce.
B. reproduce asexually.
C. reproduce sexually.
D. are multi-cellular.
Answer:
B. reproduce asexually.
Explanation:
Janet can conclude that these organisms reproduce asexually. So, the correct option is B.
What is Asexual reproduction?Asexual reproduction refers to a type of reproduction where a child is born to a single parent. The newly created people are copies of their parents since they have the same genetic makeup and physical characteristics.
Both multicellular or unicellular species can reproduce asexually. There will be no gamete fusion involved in this procedure, as well as the number of chromosomes will remain the same. With the exception of specific situations where there is a possibility that a rare mutation will occur, it will inherit the very same genes as the parent.
Therefore, the correct option is B.

Answer:
Parallax
Explanation:
"Parallax" refers to a displacement of an object's position in space (as being seen by an observer) when looking at the object along two varying sight lines. The projection of objects that are near shows a larger parallax than the objects that are farther away.
This is the phenomenon which explains why the road trees in the middle distance seem to shift in a position that is relative to the far away hills.

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.

which of these has been improved by genetic engineering
Answer:
Resistance of corn plants to insects.
Explanation:
Resistance of corn plants to insects has been improved by genetic engineering. The correct option is D.
What is genetic engineering?The modification and manipulation of an organism's genes through technology is known as genetic engineering, often referred to as genetic modification or genetic manipulation.
In order to fix genetic flaws and hence prevent or treat hereditary illnesses, gene therapy aims to change specific genes.
Genetic engineering has increased corn plants' insect resistance. R genes (resistance genes), whose byproducts mediate resistance to particular virus, bacterium, oomycete, fungus, nematode, or insect strains, have evolved inside plants.
Gene silencing is a technique used by plants and insects to effectively fight viruses.
This system views a virus as a gene that is expressing itself inappropriately. As a result, plant cells disable it by cutting the viral RNA into little bits.
Thus, the correct option is D.

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.

Please select the best answer from the choices provided
ОО
T or F
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.

Cells perform DNA replication and organelle duplication during the cell cycle to ensure that after division, daughter cells do not decrease in size but maintain full functionality. This process, which includes mitosis or meiosis depending on the cell type, is critical for proper growth, development, and health maintenance.
To ensure that cells do not just get smaller and smaller with each division, they must grow and duplicate their contents, including DNA replication and organelle duplication. Cell division is one component of the larger cell cycle, which includes preparation for division as well as the actual process of dividing. DNA replication is a critical step that occurs before a cell divides. During DNA replication, the cell's DNA is copied to produce two identical chromosomes.
This ensures that each daughter cell inherits a complete set of DNA, which is essential for producing the proteins necessary for the cell to function properly. In addition to DNA, other cellular components must also be replicated to maintain cell function and size after division. The cell cycle and processes like mitosis in somatic cells and meiosis in sex cells ensure the continuity of life and proper organism growth and development. The accurate copying of genetic information during cell division is imperative for the longevity and health of both single-celled and multicellular organisms.
