What structures allow each protist to move?
Amoeba:
Euglena:
Paramecium:
Answers
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.

Tendrá la intensidad de la luz un efecto en la velocidad de la fotosíntesis, cuando los períodos de exposición están limitados a la duración normal de la luz para una planta
Answers
Answer:
ver explicacion
Explanation:
La fotosíntesis es el proceso mediante el cual las plantas verdes fabrican su propio alimento en presencia de luz solar, clorofila, dióxido de carbono y agua.
La intensidad de la luz afecta la tasa de fotosíntesis, cuanto mayor es la intensidad de la luz, mayor es la tasa de fotosíntesis y viceversa. Cuando hay una mayor intensidad de luz, hay más luz disponible para impulsar las reacciones de la fotosíntesis.
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?
Answers
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.

Rabbits must be always aware of predators that may catch and eat them. In
natural selection what would we consider these predators?
Answers
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.

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,
Answers
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.

What is blood?Blood is a connective tissue, which is made up of several blood cells and water, it is a fluid material that transports the gases and other materials inside the body.
It includes red blood cells, white blood cells, plasma, and thrombocytes, blood is not only used to transport oxygen and carbon dioxide, but it is responsible to carry waste material to the kidney and filter the blood in body circulation.
In the human body, it maintains the homeostasis condition and fights infection by producing antibodies, this makes our body in immunized condition.

using a named examples explain the differences between a specific body defence mechanism and a non- specific body defence mechanism
Answers
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.

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.

How does the aorta compare in size to the other blood vessels near it?
Answers
Answer: Its wider and thicker than most blood vessels
Answer: The aorta is the largest blood vessel in the body. This artery is responsible for transporting oxygen rich blood from your heart to the rest of your body. The aorta begins at the left ventricle of the heart, extending upward into the chest to form an arch.
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.
