Answer:
The correct answer is - Behavioral isolation.
Explanation:
In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.
It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.
6. Which marrow was denser (had more mass in the given volume)? What impact would that have on the overall density of the bone?
Answer:
The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.

Microtubules and microfilaments are elongated structures that cross the cell, giving support to the cell, and carries organelles and objects throughout the cell. Their supporting structure would be most like which system of a multicellular organism?
Answer: Their supporting structure would be most likely the MUSCULOSKELETAL SYSTEM of the multicellular organisms.
Explanation:
The musculoskeletal system found in multicellular organisms are made up of structures which provides support, protection and allows for various movements. These structures include:
--> Muscles
--> Cartilage
--> Ligaments
--> Tendons and
--> Joints
Furthermore, Microtubules and microfilaments are the major components of cytoskeleton. They are the structures that gives a cell it's shape and helps organise it's parts. As described in the question, they are elongated structures that cross the cell, giving SUPPORT to the cell, and carries organelles and objects throughout the cell.
Therefore, since the Microfilaments and Microtubules provides support and shape at the cellular level it can be most likened to the musculoskeletal system of multicellular organisms which performs the same functions.
What structures allow each protist to move?
Amoeba:
Euglena:
Paramecium:
Amoeba moves using pseudopodia.
Euglena moves using flagellum.
Paramecium moves using cilia.
What are the structures that allow the movement in different protists?
Pseudopodia, or protruding portions, are used by amoebas to move. Its meaning is "false feet." These are membrane elongations of the cell. With its pseudopod, an amoeba can reach out and grab a surface, using it to propel itself forward.Flagellums (plural flagella), a long whip-like structure that functions as a little motor, help euglena move. On the anterior (front) end, the flagellum spins in order to propel the cell through the water.Cilia have the ability to move in unison to advance a Paramecium. When a barrier is reached, the cilia travel in the opposite direction, somewhat reversing the Paramecium's forward motion.

What the population of birds exhibits Type II?A population of birds exhibits Type II survivorship. A predator is introduced that feeds on hatchlings, causing a change in the survivorship of the birds. A survivorship curve refers to a graph showing the number or proportion of individuals surviving to each age for a given species or group. There are three types of survivorship curves as follow:
Type I curves depict individuals that have a high probability of surviving to adulthood. For example, large mammals have type 1 survivorship curves, because they have a. low infant mortality and high rates of survival into old age.
Type II curves also called as intermediate type, it depict individuals whose chance of survival is independent of age. For example, most birds have type 2 survivorship curves birds die more or less equally at each interval of their age.
Therefore, The fourth graph would most likely represent survivorship of the birds after the introduction of the predator. Thus, option D is correct.

The mountain ash produces a bright red berry fruit. How has the mountain ash tree evolved in order to allow its seeds to be spread far from their source?
A. The leaves are brightly colored and attract animals to the plant,
B. The seeds are in berries that are eaten by birds and dropped as waste away from
the plant
C. The seeds are lightweight so animals can pick them up and carry them back to
their nests
D. The seeds have light stems that allow them to be carried by the wind,
Answer:
The correct answer is - B. The seeds are in berries that are eaten by birds and dropped as waste away from the plant.
Explanation:
The mountain ash trees contain red berries fruits that attract birds and other organisms. These birds eat these berries and eat berries and fly over the hills or mountains and after digesting they drop the seeds of these berries with the digestive waste. These berries grow on the mountains far from the original source as birds carry them by flying away after eating.
Thus, the correct answer is option B.

Describe how a protein would be changed if a base sequence mutates
from GGA to TGA.
Answer:
The protein would contain threonine instead of proline
Explanation:
The shape of the protein may be changed when a base sequence mutates from GGA to TGA.
What do you mean by Mutation?A Mutation may be defined as a sudden, stable, and inheritable change that occurs in the genetic material of an organism.
The amino acid sequence would be different, as GGA codes for Glycine, while UGA or TGA codes for stop codon which terminates the process of protein synthesis.
The protein which may be synthesized may not work correctly. In other words, the protein would be functional less.
Therefore, the shape of the protein may be changed when a base sequence mutates from GGA to TGA.

using a named examples explain the differences between a specific body defence mechanism and a non- specific body defence mechanism
Answer:
Specific body defence mechanism are resistance that are directed against only one specific invader while,
Non specific defence mechanism protects against any of an enormous range of possible dangers.
Explanation:
NON SPECIFIC DEFENCE MECHANISM are the first lines of general defence, they prevent entry and minimise further passage of microbes and other foreign material into the body. There are five main non specific defence mechanisms, these include:
--> defence at body surface
--> phagocytosis
--> natural antimicrobial substances
--> inflammatory response
--> immunological surveillance
Using PHAGOCYTOSIS as a named example of non specific defence mechanism. This involves phagocytes such as the macrophages and neutrophils which are able to trap any invading microbes either by engulfing them or by extending long pseudopodia towards them which grasp them and reel them in. These cells are NON SELECTIVE in their targets.
SPECIFIC BODY DEFENCE MECHANISM directs its actions against a specific invader. In addition immunological memory develops which confers long term immunity to specific infections. The immunity could be cell mediated or antibody mediated immunity.
Using CELL MEDIATED IMMUNITY as an example, Cytotoxic T-cells directly inactivate any cells carrying antigens. This means they are SELECTIVE in their targets. They attach themselves to the target cell and release powerful toxins, which are very effective because the two cells are so close together. This leads to destruction of abnormal body cells such as infected cells and cancer cells.

Rabbits must be always aware of predators that may catch and eat them. In
natural selection what would we consider these predators?
Answer:
There are many rabbit predators that will attack or eat the rabbit, including man. In fact, rabbits have more than most.
Explanation:
Depending in which part of the world you live, will determine the most likely predators you need to be aware of. With domestic/pet rabbits, perhaps the most common predators are pet dogs, pet cats and foxes. However, don't think these are the only ones. Many people are surprised to learn that large birds are a predator to rabbits, especially if the rabbit is a baby, young or a small breed type. Such birds, depending on where you live, include Hawks, Sparrow Hawks, Owls, Falcons, and kestrels. Other rabbit predators include Weasels, ferrets, badgers, stoats and snakes.
