The most often utilized research techniques in psychology are correlational, case, and experimental studies. Any field, including biological psychology, shares this.

The biological approach examines psychological problems by looking at the physical underpinnings of both animal and human behavior. It is one of the main views in psychology and includes research on the neurological system, immune system, and brain.

The fear reaction is an illustration of the biological approach to psychology. The fight, flight, or freeze response is the result of the fear response. What a person does in the presence of a stressor depends on their biological makeup.

c. make the data more valid.

Explanation:

She was most likely to make the noted data more valid and accurate with the help of new measurements.

An experiment may be defined as a procedure that involves the complete set of methodology in order to test a hypothesis and reveals an appropriate conclusion or evidence that supports the hypothesis.

It is foremost required during experiments that the measurement of reference objects or things should be taken multiple times.

This approach reduces the chances of mistake and makes the data more valid and accurate.

First, we must understand that before limbless snakes, there was an ancestor that possessed limbs. In the population of this ancestor, a mutation occurred in one of the individuals that caused it not to develop limbs.

Currently, the data suggest that the loss of limbs was due to the Sonic hedgehog gene and the regulatory region of this gene, the ZRS region.

The mutation (a deletion or loss of nucleotides) in the regulatory region (ZRS) meant that the sonic hedgehog gene could not be expressed correctly and therefore the gene could not drive limb development.

We already know how the loss of limbs occurred, now the question is, how was this feature maintained over time?

Today, snakes do not have limbs because the limbless ancestor was able to reproduce in a great way and therefore its descendants have lasted until today. This was probably because the lack of limbs gave it an advantage and a greater survival compared to the other animals in the population that did have limbs.

INTERKINESIS:

Interkinesis is also known as interphase II that occurs during meiosis, between meiosis I and meiosis II.

No DNA replication takes place during this phase.

Specifically in plants when two daughter cells are produce by the process of meiosis I, immediately they prepare for meiosis II.

During this period nuclear envelope begin to appear for temporary, which is known as interkinesis that helps in the separation of two sets of chromosomes.

Starling is a bird from the family sturnidea. It originated from Europes and Asia from where it introduced to other part of the world. They lives in the wild.

Starling birds moves in group or tight flock from a place the other. They usually form a flock called murmuration where they move together in group following each other to avoid predation.

Starling have been able to survive on the wild with this behaviour. They stir above the average height of their neighbor in a coordinated manner preventing them from being caught by preys.

If it remains in complete remission for 5 years or more, it can usually be considered cured. Even so, some cancer cells can remain in the body for many years after treatment and cause the cancer to come back one day.

Abnormal cell development is caused by a defect in the DNA. These changes can be inherited from parents, pop up spontaneously or result from external agents such as cigarettes, viruses, excessive exposure to the sun, obesity and consumption of certain foods. These are the carcinogenic factors.

More than 10 million people die each year from cancer, WHO reveals

Cancer arises from a genetic mutation, that is, from an alteration in the cell's DNA, which starts to receive wrong instructions for its activities. Changes can occur in special genes, called proto-oncogenes, which are initially inactive in normal cells.

When plants and animals undergo cellular respiration, energy in the form of ATP is produced.

Cellular respiration involves chemical reactions which breakdown glucose in order to produce ATP which provide energy to the organisms in order to perform a number of activities like digestion, movement, metabolism etc. The chemicals which are involved during respiration are catabolic in nature, that is, they involve the breakdown of the larger substances into smaller ones.

The chemical energy is converted into ATP, which can be used by the body of the organism. The three major steps of cellular respiration are the glycolysis, Kreb's cycle or the citric acid cycle and oxidative phosphorylation.

Peptide hormones are signaling molecules made up of short chains of amino acids. These molecules are generally large, water-soluble molecules that cannot cross the lipid bilayer of the cell membrane on their own.

The receptor proteins on the surface of the cell membrane help to recognize these hormone molecules and initiate cellular responses. Here are four receptor types that could be facilitating the actions of peptide hormones: G protein-coupled receptors: G protein-coupled receptors (GPCRs) are the largest family of cell surface receptors.

These receptors interact with G proteins that can activate or inhibit second messenger pathways. Most peptide hormones interact with GPCRs, which in turn activate downstream signaling cascades.

Explanation:

Large holes in the ground left over after the mining operations are sometimes known as the pinge. These are made up by the mining activities that are making the depression or the sink holes in it.

It is the human activity in which the extractions are done in order to make the use of the resources . It is the artificial human activity.

This depression or sink-hole is usually caused out  by collapse of  the old underground mine works which are close to Earth's surface.Unlike  any natural landforms , a Pinge is the  direct result of  the human activity. The collapses do  make up big larger holes that almost  makes the pinges in the process of mining.

Pinge is also formed by the surface in which the land is not supported properly and the extraction has made the holes in the lands because of the more pressure and the type of extracting machines that are being used in it.

The mechanism whereby an enveloped virus leaves a host cell is called   budding.  option 3)

Virus can reproduce only within a host cell, this cycle of infection begins with the attachment, where the virus attaches to a specific receptor site on the host cell, after this comes the entry, in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis.

After entering the cell the virus initiates a replication  and assembly mechanism depending on its genome, finally, the last stage of viral replication is the release or egress of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.
