3)What are some examples of specialized cells
and what do they do?
4) Why is the specialization of cells in organisms
significant and important for homeostasis?
Answer:
3 Neurons are the specialized cells responsible for allowing all the basic body functions to take place correctly as all the necessary communication happens through them. Muscle cells or myocyte cells are specialized in making all movement possible. These cells have a cylindrical shape that allows them to contract.
Explanation:
4 Each cell must be able to perform as a part of a living organism. Cell specialization is required for cells to perform as a part of a whole living thing. Different cells do different jobs.
There are 100 ants in an ant farm that is 10 inches by 5 inches. What is the population 1 density? (Show your work)
The population density would be 2 ants/square inch
Population density is defined as the population size of a species of organism per unit area of the habitat occupied.
In this case, the population size of ants in the ant farm is 100 while the dimension of the ant farm is 10 inches by 5 inches.
Area of the ant farm = Length x breadth
= 10 x 5
= 50 square inch
Population density of ant = population size/area
= 100/50
= 2 ants/square inch

why cellular respiration and photosynthesis are a
cycle.
Cellular respiration and photosynthesis are referred to as a cycle because the end product of one process serves as the starting material for the next reaction. During cellular respiration, sugar and water are the starting materials, and carbon dioxide and water are the byproducts. Water and carbon dioxide are the starting material for photosynthesis.
ExplanationA cycle is a series of steps that are repeated, which defines this! :)

1. Based on your observations, is it possible that bacteria can thrive in
a sealed can and cause vegetables to spoil?
Answer:
Explanation:
When bacteria and other nasty pathogens are heated beyond a certain temperature (usually the boiling point of water – 212 degrees Fahrenheit), they are neutralized or killed. Since the can is sealed before this heating process occurs, no additional bacteria or spores can make it into the can.

What is a
method of fishing that involves surrounding the schools of fish with a net which is then drawn
together to enclose them
Answer:
Purse seines
Explanation:
Purse seines are used in the open ocean to target dense schools of single-species pelagic (midwater) fish like tuna and mackerel. A vertical net 'curtain' is used to surround the school of fish, the bottom of which is then drawn together to enclose the fish, rather like tightening the cords of a drawstring purse.
Which of the following IS NOT a model of motivation?
A. Self-actualization B. Cognitive
C. Expectancyvalue D. Psychoanalytical
Positive reinforcement is not a component of expectancy model of motivation. Positive reinforcement can be defined as giving something to the subject when they perform the desired action so they associate the action and do it more often and hence, positive reinforcement is not related to expectancy model of motivation.
An internal act or process that aids the individual conduct to achieve the purpose. The model of motivation includes the strategies, goals, and influences that lead the person to follow the decisions.
The following is not the model of motivation:
Option D. Psychoanalytical
Model of motivation can be explained as:
Self-actualization is the realization of potentials and talents possessed by individuals.The conscious intellectual activity is called cognitive and affects motivation.The attitude of individuals towards the action and problems are called expectancy values.Therefore, psychoanalytical is not a model of motivation.

What is the mechanism by which the secretion of a hormone is followed by travel to a distant target cell
Answer:
induction or repression of enzymes
Explanation:
Hormones are chemical messengers which are secreted by endocrine glands and regulate the rate of existing activities, usually through the induction or repression of enzymes within distant target cells via the endocrine system. They travel in the bloodstream, having slower, but longer lasting effect and are effective in small quantities.
hope it helps
The mechanism by which the secretion of a hormone is followed by travel to a distant target cell is primarily through the bloodstream. Once in the bloodstream, hormones are carried throughout the body, allowing them to reach their target cells or tissues.
Hormones are usually released in small amounts but have potent effects on target cells. The binding of a hormone to its specific receptor triggers signaling pathways within the target cell, leading to changes in cellular function or gene expression.
The travel of hormones through the bloodstream ensures their widespread distribution and enables them to reach distant target cells located in different organs or tissues.
This mechanism allows hormones to exert their regulatory effects on various physiological processes, including growth and development, metabolism, reproduction, and homeostasis.

True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

The published data for the map distance between the gene and the centromere is 26 map units. You just calculated the map distance as 17 map units. What is the best explanation for this disparity
Linkage maps and physical maps are NOT the same. A linkage map measures the number of recombination events in a given chromosome fragment.
A linkage map is based on the frequency of recombination events between genes or molecular markers.
This frequency indicates the number of events in which a single chromosomal fragment recombines between two or more genes or molecular markers during meiosis.
Conversely, a physical DNA map indicates the physical locations of genes (molecular markers) and nucleotide (DNA) sequences of interest, which is useful to identify genes by positional cloning.

The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the:
Answer:auditory tube
Explanation
The structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
What is the structure of Ear?The ear is a type of organ of hearing and balance which consists of a cavity in the skull structure lined with soft tissue. It surrounds three distinct spaces filled with air or fluid i.e. the outer, middle, and inner ear. These specialized spaces host both the sound transmission apparatus and the sensory apparatus.
Types of bones present in the ear are
1. Hammer shaped bone known as malleus which is attached to the eardrum.
2. Anvil shaped bone known as incus present in the middle of the chain of bones.
3. Stirrup shaped bone known as stapes is attached to the membrane-covered opening which connects the middle ear with the inner ear (oval window).
The cavity of the middle ear is a narrow air-filled space which is a slight constriction divides it into an upper and a lower chamber known as tympanic cavity proper below and the epitympanum above. The main function of the Eustachian tube is to equalize the air pressure between the environment and the middle ear.
Thus, the structure that regulates air pressure between the external atmosphere and the middle ear cavity is known as the Eustachian tube.
