Compared to the endocrine system, the nervous system has afaster response, but the signal does not last as long.slower response, and a signal that does not last as long.faster response with a longer-lasting signal.slower response with a longer-lasting signal.
Answer:
Has a faster response, but the signal does not last as long.
Explanation:
The nervous system uses action potentials to transmit signals. Action potentials have a short duration and travel fast through neurons to inform in a fast way about different stimuli and allow rapid answers. On the other hand, the endocrine system uses chemical molecules to transmit their signals. As they travel through blood or together with other molecules, their signal is not transmitted as fast as in the nervous system. However, when they reach their destination and interact with the proper molecules, they start a series of changes that have a lasting effect in contrast with the nervous system.

Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Cells must be able to perform certain functions in order to survive. Which of the following must all cells do to survive?
Hello there, mate! Let's solve together:
With the end goal for cells to endure, they require supplements as glucose and minerals in addition to oxygen.
Moreover, they need to discard byproducts. Cells additionally depend on their organelles and dissemination for endurance.
Without oxygen, minerals and the evacuation of side-effects, cells don't endure.

What type of species is most likely to lead to extinction of another species? a Invasive species b Native species c Genetically isolated species d A and B
Answer:
A
Explanation:
Like Christopher Columbus
:)
The type of species that is most likely to lead to the extinction of another species is known as Invasive species. Thus, the correct option for this question is A.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Invasive species are those that are not native to a particular habitat. They just arrive there in search of resources that support them in order to survive and reproduce naturally.
These arrived species utilize the resources like food, space, etc. of the native species and make them oppressed to eliminate from this habitat.
Therefore, invasive species is the type of species that is most likely to lead to the extinction of another species. Thus, the correct option for this question is A.

La fórmula de la velocidad es (Velocidad = desplazamiento / tiempo). La fórmula de la altura de un triángulo es (Altura = 2 x área / ancho). La fórmula del peso es (Peso = masa x gravedad). Con la ayuda de estas fórmulas podemos encontrar el valor de velocidad, altura y peso si los datos requeridos están disponibles. La unidad de velocidad es metro / segundo, la altura es metro y el peso es kilogramo metro / segundo cuadrado.
At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the ______________ layers and a second runs through the _____________ layers.
At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the parvocellular layers and a second runs through the magnocellular layers.
What are parvocellular and magnocellular layers?Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus.
Moreover, magnocellular cells make up the magnocellular layers of the lateral geniculate nucleus. They are relatively large cells that display specialization in detecting aspects of movement, such as the location, speed, and direction of a moving object.
Therefore, magnocellular (M) and parvocellular (P) neuronal pathways that originate in the retina and project to separate M- and P-dedicated layers of the lateral geniculate nucleus (LGN) situated in the thalamus.

Answer:
The leaf kept in the light will turn blue-black because of the presence of starch after photosynthesizing. The leaf in the dark could not photosynthesize, which would not create starch so the iodine solution will have no effect.

PLS HELP IT IS DUE IN 20 MINUTES.
Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.

After reviewing the photo
we have
Genotypes
B: 50% (1/2)
b: 50% (1/2)
Phenotypes
Black: 50% (1/2)
brown: 50% (1/2)
Using Punnett Squares, the percentage of offspring would be heterozygous from the following cross: BB x bb is 25%. Therefore, option (A) is correct.
What are the features of punnett square method?The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905.
The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given. In its simplest form, the Punnett square consists of a square divided into four quadrants.
A Punnett Square is a helpful tool that helps to predict the variations and probabilities that can come from cross breeding. This includes predicting crossing plants, animals, even humans with each other.
