12% of butterflies in the population have homozygous dominant genetic makeup. If there were 4,216 people in the population, then there would be 48% heterozygous butterflies.

In the absence of other evolutionary factors, the Hardy-Weinberg principle asserts that allele and genotype frequencies remain constant from generation to generation.

Brown (B) outnumbers white (b) in proportion to the population's characteristics.

Recessive phenotype frequency

(Q)= 40%

Q = 0.4

According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.

So then, P = 1-Q

P = 1-0.4

P = 0.6

Heterozygotic butterflies = 2PQ

So, 2PQ= 2x0.6x0.4

=0.48

So, 48% of the population is heterozygous.

Homozygous dominant individual frequency = 1 - (40 + 48) = 12 i.e. 12%.

The correct words to complete the sentence, and the completed sentence are; Mushrooms are fungi that use spores for reproduction.

Fungi is a kingdom made up of a group of organisms that include molds, yeasts, and fungi. They are heterotrophic organisms that have cell walls. Fungi cannot form their own nutrients so they live as parasites on the plants and animals around them. The fungi that form in humans can coexist in these without causing any infection, but some can produce them. Fungi can reproduce using spores and disperse until they find favorable conditions to germinate.

"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.

The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.

Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.

The dew point temperature is 6°C when the difference between wet-bulb and dry-bulb temperatures is 4°C and the dry-bulb temperature is 14°C.

To calculate the dew point temperature, a table is used instead of a formula. To determine the dew point temperature the dry-bulb temperature (which is 14°C in this case) on the left side of the table is noted and then the difference between wet-bulb and dry-bulb temperatures, i.e. 4°C is noted given on the top of the table. Now the cell where these row and column meet gives the value of the dew point temperature, which comes out to be 6°C.

If everyone in a neighborhood applies fertilizer to their lawn, they could fall into The Tragedy of the Commons. TRUE

The tragedy of the commons is an economic problem of over-consumption, under-investment, and ultimately depletion of common resources. The tragedy of the commons is a situation in which individual users who have free access to resources are not constrained by shared social structures or formal rules governing access.

The tragedy of the commons is caused by externalities. When family herds graze on common land, the quality of land available to other families is reduced. Humans ignore this negative externality when deciding how many sheep to own, resulting in an overabundance of sheep. Fertilization can affect the accumulation of heavy metals in soil and plant systems. Plants can absorb fertilizer through the soil and enter the food chain.

The scenario that is most likely to occur by Passive transport is the movement of small, non-polar molecules across the cell membrane with their concentration gradient. Thus, the correct option for this question is C.

Passive transport may be defined as a type of transport that significantly occurs along the concentration gradient without the use of metabolic energy. Passive transport is divided into two types, i.e. Simple diffusion and facilitated diffusion.

In simple diffusion, no transporters are needed and depend on the chemical gradient while facilitated diffusion is a carrier or transporters mediated diffusion which depends on the electrochemical gradient. The mechanism of passive transport is spontaneous i.e. no need for energy from outside.

Therefore, the correct option for this question is C.

Explanation:

single neuron, or nerve cell, can do a lot! It can maintain a resting potential—voltage across the membrane. It can fire nerve impulses, or action potentials. And it can carry out the metabolic processes required to stay alive.

A neuron’s signaling, however, is much more exciting—no pun intended!—when we consider its interactions with other neurons. Individual neurons make connections to target neurons and stimulate or inhibit their activity, forming circuits that can process incoming information and carry out a response.

How do neurons "talk" to one another? The action happens at the synapse, the point of communication between two neurons or between a neuron and a target cell, like a muscle or a gland. At the synapse, the firing of an action potential in one neuron—the presynaptic, or sending, neuron—causes the transmission of a signal to another neuron—the postsynaptic, or receiving, neuron—making the postsynaptic neuron either more or less likely to fire its own action potential.

Schematic of synaptic transmission. An action potential travels down the axon of the pre-synaptic—sending—cell and arrives at the axon terminal. The axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.

Schematic of synaptic transmission. An action potential travels down the axon of the pre-synaptic—sending—cell and arrives at the axon terminal. The axon terminal is adjacent to the dendrite of the post-synaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.

In this article, we'll take a closer look at the synapse and the mechanisms neurons use to send signals across it. To get the most out of this article, you may want to learn about neuron structure and action potentials first.

Electrical or chemical transmission?

At the end of the 19th and beginning of the 20th century, there was a lot of controversy about whether synaptic transmission was electrical or chemical.

Some people thought that signaling across a synapse involved the flow of ions directly from one neuron into another—electrical transmission.

Other people thought it depended on the release of a chemical from one neuron, causing a response in the receiving neuron—chemical transmission.

We now know that synaptic transmission can be either electrical or chemical—in some cases, both at the same synapse!

Chemical transmission is more common, and more complicated, than electrical transmission. So, let's take a look at chemical transmission first.

Overview of transmission at chemical synapses

Chemical transmission involves release of chemical messengers known as neurotransmitters. Neurotransmitters carry information from the pre-synaptic—sending—neuron to the post-synaptic—receiving—cell.

As you may remember from the article on neuron structure and function, synapses are usually formed between nerve terminals—axon terminals—on the sending neuron and the cell body or dendrites of the receiving neuron.

Schematic of synaptic transmission. An action potential travels down the axon of the presynaptic—sending—cell and arrives at multiple axon terminals branching off from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse.

The air that is breathed in contains oxygen in a concentration of 20% while the air exhaled still contains oxygen in a concentration of 16%. This implies 4% oxygen has been absorbed by the blood cells per breath.

Therefore, the air from the nose, mouth, and windpipe still contains all of the oxygen when we exhale, and this accounts for the 16% of oxygen that is lost during breathing.

The sympathetic nervous system and the parasympathetic nervous system are parts of the peripheral nervous system which have opposing effects.

The sympathetic nervous system keeps the body alert by activating the body's “fight-or-flight” response. The hearts beats faster, the respiratory rate increases, and the pupils dilate.

The parasympathetic nervous system relaxes the body after periods of stress or danger. The hearts beat normal, the respiratory rate normalizes, and the pupils constrict.
