Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm  to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of  inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium  gated channels, which  were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.

When the cell is at the resting membrane potential (-70 mv), both the chemical and electrical forces are channeled into the cell.

Define resting membrane potential

The electrical potential difference across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is traditionally used to describe the electrical potential difference across a cell membrane.

Any ion's equilibrium potential value is determined by the gradient of that ion's content across the membrane. The force of the concentration gradient and the equilibrium potential would both be zero if the concentrations on the two sides were identical.

The most accurate description of the pH scale is that the lower pH correlates with a higher concentration of hydrogen ions in solution. Thus, the correct option is A.

The pH scale is used for the measurement of how acidic an object is. Objects which are not very acidic are called as basic substances. The scale of pH has values ranging from zero which is the most acidic value to 14 which is the most basic value. The pure water has a pH value of 7, this denotes that it is a neutral substance. pH can be defined as the power of hydrogen ions present in the solution.

A lower pH value correlates with a higher concentration of the hydrogen ions in that solution. A higher pH value correlates with a higher concentration of hydrogen ions in the solution. And, the solutions with a pH value less than 7 are said to be basic.

Arthropods have appendages with joints. Arthropods do have legs in general.

A group of invertebrate animals known as arthropods has segmented bodies, jointed legs, and an exoskeleton. It is the invertebrate species' largest phylum. Their body is made up of segments and has two appendages. For terrestrial species, internal fertilization as well as external or internal fertilization is used for reproduction (aquatic species). Their circulatory system is open. Their development began during the Cambrian era. They serve as pollinators for crops and a source of food for people. Some species can infect people, animals, and crops with diseases.

All arthropods have joined limbs (arthro means joint, and pod means foot). The exoskeleton is rigid across much of the leg, but it is softer and pliable at the joints, allowing movement much like a suit of armor does.

All arthropods have moving body parts, joint legs, and claws. The bodies of arthropods are segmented. Typically, each body segment contains two appendages. The appendages may be mouthparts, legs, wings, or antennae.

The population that uses sexual reproduction will have increased genetic diversity which will allow the population to adapt to the changing environmental conditions.

Genetic diversity is the term used to describe the amount of variation in a population's genetic material. Genetic diversity is important for the long-term health and survival of a species, as it allows them to adapt to changing environmental conditions. It is also important for the health of a population, as it prevents inbreeding, which can cause genetic defects. Genetic diversity can be measured in a number of ways, including looking at the number of different alleles in a population, the amount of genetic variation in a population, and the amount of variation between individuals within a population. Genetic diversity is influenced by a variety of factors, including mutation, natural selection, and gene flow. Ultimately, genetic diversity is essential for the survival of a species, and it is important to maintain and promote a healthy level of genetic diversity in order to ensure a species’ long-term survival.

mass of water = 135 kg which is equivalent to 135 liters

To \(cm^2\); we have:

1 liter = 100 \(cm^2\)

5 liter = 292 \(cm^2\)

∴

135 L will yield 2631.616 \(cm^2\)

However, converting this into MegaJoules

Recall that:

cal/\(cm^2\) = 1 calorie or 4.19 Joules

4.19 Joules = 4.19 × 10⁻⁶ MegaJoules

Hence;

2631.616 \(cm^2\) = (2631.616 ×  4.19 × 10⁻⁶) Mega Joules

= 0.0110264878

= 11026.47 × 10⁻⁶ Mega Joules per day

Explanation:

Process of elimination  

Answer: Answer is B, Younger than 400 million years

Explanation:

The age of rock layers in a stack reflects the order in which they were deposited—the lower layers were laid down first, and then the upper layers were laid on top of them. So, the lower layers and fossils they contain are older than the upper layers and fossils. This is known as the principle of superposition.

In this example, Layer 1 was deposited first, then Layer 2, Layer 3, Layer 4, and Layer 5. Layer 1 is the oldest, and the layers get younger as you move up through the stack.

If the age of a particular layer is known, then the relative age of other layers can be determined. In this example, Layer 4 is 400 million years old. This means that the layer above it is younger than 400 million years and the layers below it are older than 400 million years. Layer 1 is 500 million years old. This means that layers above it are younger than 500 million years.

Layer 5 is above Layer 4, so it must be younger than 400 million years.

By using detection antibodies specific for the infected carrier

Explanation:

The enzyme-linked immunosorbent assay (ELISA) assay is widely used in molecular biology (and biochemistry) laboratories to detect and measure antibodies in the blood. The antibodies are specific immunoglobulin proteins produced by B lymphocytes, these molecules bind to specific antigens present in pathogenic microorganisms during adaptive (acquired) immune responses, thereby protecting the organism against infectious agents. In consequence, the ELISA assay is a diagnostic method to assess the immune system responses against pathogenic microorganisms. The ELISA technique is specific because it is possible to use different detection antibodies, which bind to specific antigens in the polystyrene microtiter plate.

The behavioral, humanistic, and cognitive approaches provide different perspectives on the origins and treatment of Jake's anxiety.

The behavioral approach would view Jake's anxiety as a learned response that has been reinforced over time. They might suggest that Jake's anxiety is a result of negative experiences or associations with his academic performance, leading to increased anxiety symptoms. Treatment would focus on identifying and modifying maladaptive behaviors through techniques such as exposure therapy and behavior modification.

The humanistic approach would emphasize Jake's self-actualization and personal growth. They might view his anxiety as a result of a discrepancy between his self-concept and the challenges he is facing in his major.

Treatment would involve providing a supportive and empathetic environment where Jake can explore his feelings and values, with the goal of helping him align his personal goals with his academic pursuits.

The cognitive approach would focus on Jake's thoughts and beliefs about his academic performance. They would suggest that his anxiety stems from negative and distorted thinking patterns, such as excessive self-criticism or catastrophic thinking.

Treatment would involve cognitive restructuring, helping Jake identify and challenge irrational thoughts, and developing more adaptive and realistic thinking patterns.

In contemporary psychology, these approaches are not seen as mutually exclusive, but rather complementary. Psychologists recognize that a multidimensional approach, integrating elements from different perspectives, can provide a more comprehensive understanding of psychological issues.

Treatment approaches often combine techniques from various approaches to address the unique needs of each individual, emphasizing a holistic and personalized approach to mental health.
