All I can tell you is when energy is moves through the food web it gets divided by 10

plant energy =1 0,000 (example)

that plant gets eaten by a small animal

small animal's energy gained from the plant  = 1,000

a large animal then eats the smaller one

large animal's energy gained from the small animal = 100

Exocytosis is highly specialized in secretory cells and neurons, is highly regulated, and constitutes the main cellular mechanism for neurotransmitter secretion.

It involves the fusion of the vesicular membrane to the plasma membrane, in a calcium-dependent manner that releases molecules that perform specific functions in the body.

Neurotransmitter exocytosis is an essential part of presynaptic transmission and, by extension, of the functioning of the nervous system.

Therefore, we can conclude that exocytosis is highly specialized in secretory cells and neurons, is highly regulated, and constitutes the main cellular mechanism for neurotransmitter secretion.

The release of neurotransmitters from the presynaptic cell is an example of exocytosis.

Neurotransmitter is saved interior small sacs known as synaptic vesicles and is launched into the synaptic cleft of the synapse while a vesicle fuses with the cell membrane.

When a movement capability depolarizes the presynaptic plasma membrane, Ca2+-channels open, and Ca2+ flows into the nerve terminal to cause the exocytosis of synaptic vesicles, thereby freeing their neurotransmitters into the synaptic cleft.

Answer:

it does not have any hidden heat.

Explanation:

Ice at 273K or 0°C is more efficient in cooling as it does not have any hidden heat. Water at the same temperature has hidden heat, banned latent heat of fusion, which is used to convert water into ice. Thus, ice at 273 K is more effective in cooling

hey could i have brainlesit answer thanks i worked hard :)

Ice at 273K is more effective in cooling than water at the same temperature as ice absorbs more heat to overcome the latent heat of fusion, as a result, provides the cooling effect.

Latent heat of fusion is the energy that must be provided to the solid matter so that there is a change triggered in the physical state of the matter, and as a result, leads to the formation of the liquid.

Ice at 273 K has a cooling effect as there is no hidden heat and latent heat, unlike the water that has hidden heat that makes them less cool than the ice at the same temperature.

Therefore, the ice exhibits a cooling effect at 273 K.

The percentage of moths in the natural population that was white in 1962 is : 4%

Hardy-weinberg equilibrium states that the sum total of all the genes of an individual in a population is constant when the disturbing factors such as genetic drift does not occur

p² + q² + 2pq = 1

Applying the equation below

p² + q² + 2pq = 1

p = frequency of dominant allele

q = frequency of recessive allele

q² = frequency of h0m0zygous recessive genotype

p² = frequency of h0m0zygous dominant genotype

From the graph

Frequency of G allele ( i.e p ) = 0.8

percentage of white moths = q²

Note : p + q = 1  ---- ( 1 )

Insert value into equation ( 1 )

0.8 + q = 1

therefore ; q = 0.2

Hence the percentage of white moths = ( 0.2 )² = 0.04

                                                                               = 4%

Hence we can conclude that The percentage of moths in the natural population that was white in 1962 is : 4%

The change in allele and genotypic frequencies in a population is evidence of gene flow.

The term gene flow makes reference to the interchange of genetic material between individuals of two or more populations.

The gene flow generates a change in the allele and genotypic frequencies in the individuals of a population in equilibrium.

The gene flow may be due to migration and this phenomenon must be mediated by reproduction.

Answer:

two traits ,

Explanation:

In an example of pleiotropic genes, the flower color gene studied by Mendel affected a single trait.

Pleiotropy refers to a phenomenon where a single gene influences multiple, seemingly unrelated traits or characteristics in an organism. However, in this specific case of Mendel's flower color gene, it affected only one trait, which is the color of the flower.

Genes are the basic factors of inheritance. They are found in the DNA of all living organisms. They are responsible for transmitting genetic information from one generation to the next and play a crucial role in determining an organism's traits and characteristics.

Answer:

By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.
