Bacteria, Viruses, Fungi and Protists are the four major groups of human pathogens. Therefore, option (A) is correct.
What are human pathogens?Bacteria are microorganisms that are made up of a single cell and can be the source of illnesses such as strep throat, TB, and infections of the urinary system. The common cold, influenza, and COVID-19 are all illnesses that can be caused by viruses, which are non-living particles that can only multiply inside of a living host cell.
Infections such as ringworm, athlete's foot, and thrush can be caused by fungi, which are multicellular organisms that can spread from person to person. Protists are single-celled organisms that are capable of causing a variety of diseases, including giardiasis, malaria, and amoebic dysentery.
Insects and toxins, despite the fact that they are capable of inflicting harm on humans as well, are not considered to be major classes of human pathogens.

* C.
They cause similar cells to link together to form larger organisms.
* D.
They help the cell membrane absorb nutrients from the environment.
Answer:
A
Explanation:
Both cilia and flagella are important locomotory organs. These organelles are specialized to cause the movement of the cell from one place to another in the environment. Thus, the correct option is A.
What are locomotory organs?Locomotion is the directional movement of cells that enables something to move from one place to another place. The word locomotion is derived from the Latin words loco which means place and motio means to move.
The anatomical structures which animals posses for the movement, includes cilia, legs, wings, flagella, or tails, these are referred to as the locomotory organs. These are present on the body of animals to defend themselves in extreme conditions, in capturing the food or prey. The cilia are hair-like organs which are present all over the surface of a cell where flagella is a large whip-like structure which are present single or in pair in a cell.
Therefore, the correct option is A.

7. What is the difference between simple diffusion and facilitated diffusion?
8. Compare (give similarities and differences) between diffusion and osmosis.
9. Why are diffusion and osmosis are important for living organisms?
Answer/Explanation:
[1] The three parts of the cell theory is all organisms are made of cells. Cells are the smallest unit of life and new cells arise from existing cells.
[2] The three structure that Eukaryotic and Prokaryotic cells have common is plasma membrane, ribosomes, cytoplasm, and DNA.
[3] The difference between prokaryotic cells and eukaryotic cells is prokaryotic cells has no nucleus while, eukaryotic cells have a nucleus.
[4] One example of a specialized animal cell is Muscle Cell. Muscle cells bring parts of the body closer together. They contain protein fibres that can contract when energy is available, making the cells shorter.
[5] One example of a specialized plant cell is cell wall. Cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting.
[6] The three factors that affect the rate of diffusion is temperature, concentration gradient, size of the molecule.
The size of the molecule: The smaller the molecule such as gas, the faster the rate of diffusion while the larger the molecules (liquid) the slower the rate of diffusionConcentration gradient: Diffusion takes place as long as there is a difference between the concentration gradient of substances across a barrier. The more is the concentration difference, the higher is the driving force, the faster the rate of diffusion. When the concentrations of the substance on either side of the barrier become equal, the diffusion stops.Temperature:The higher the temperature is, the faster the speed of diffusion. Temperature increases the K.E. (kinetic energy) of a molecule and it helps to move the molecule faster and hence the speed of diffusion increases.[7] The difference between simple diffusion and facilitated diffusion is simple diffusion, the movement of particles occurs along the direction of the concentration gradient. While in facilitated diffusion, the movement of molecules can occur both in direction and opposite of the concentration gradient.
[8] The similarities between diffusion and osmosis is they both particles move from an area of higher concentration to one of lower concentration. The difference between diffusion and osmosis is diffusion can occur in any mixture, including one that includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.
[9] Diffusion and osmosis are important for living organisms because diffusion and osmosis both even forces inside cells and organisms as a total, expand water, nutrients and necessary chemicals from areas that contain a high concentration to areas that contain a low concentration.

Why does the Earth experience two high and two low tides each day?
Answer:
When the moon pulls on one side of Earth, the other side experiences high tide as well.
Explanation:
During the day, the moon revolves around Earth and when it does, it pulls on the oceans, causing high tide number one. But, when the moon pulls on one side of the Earth, the other side also bulges out, causing high tide number two. Think of this as a squishy ball. When you hold it with your index finger on the top and your thumb on the bottom and squeeze it, both sides of the ball bulge out. This is what happens to the Earth under the moon's gravitational pull.

What are the tropical zones and the temperate zones?The tropical zones and temperate zones are broad geographic regions of the Earth that are defined by their climate and location relative to the equator.
The tropical zones, also known as the tropics, are the regions of the Earth that lie between the Tropic of Cancer (23.5 degrees north of the equator) and the Tropic of Capricorn (23.5 degrees south of the equator). These regions are characterized by warm to hot temperatures year-round, high humidity, and frequent rainfall, resulting in lush vegetation and diverse animal life.
The temperate zones, on the other hand, are the regions of the Earth that lie between the Tropic of Cancer and the Arctic Circle (66.5 degrees north of the equator), and between the Tropic of Capricorn and the Antarctic Circle (66.5 degrees south of the equator). These regions are characterized by distinct seasonal changes in temperature and precipitation, with warm summers and cool to cold winters.

What is the end result of meiosis 1?
(Please please help :(
a. Haploid gametes
b. Two haploid daughter cells c. Four haploid daughter cells
d. A genetically identical cell
Answer:
THE ANSWER IS B TWO HAPLOID DAUGHTERS CELLS
Explanation:
In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent.
The result of meiosis is four haploid daughter cells.
WHAT IS MEIOSIS:
Meiosis is a cell division that results in the formation of four daughter cells with each cell possessing a reduced number of chromosomes (by half). Meiosis is also called reduction division because it reduces the chromosome number of the parent cell by half. For example, human cells with 46 chromosomes (diploid) undergo meiosis to form four daughter cells with 23 chromosomes (haploid) each. However, the four daughter cells are genetically different from the parent cell.Therefore, the result of meiosis is four haploid daughter cells.

Sinkhole
Cave
Which of these statements is correct about the sinkhole and cave shown in the pictures?
O Both are formed by the heating of groundwater.
Both are formed by the chemical reaction between limestone and groundwater
The sinkhole is formed by the the heating of groundwater and the cave is formed by the chemical reaction between limestone and groundwater.
O The sinkhole is formed by the chemical reaction between limestone and groundwater and the cave is formed by the heating of groundwater.
Answer:
B). Both are formed by the chemical reaction between limestone and groundwater.
Explanation:
The second statement correctly states that both Sinkhole and Cave as shown by the picture are created as a result of the chemical reaction that takes place between the groundwater and limestone. The sinkholes are characterized as the cavities that form in soluble rock by the action of water. It is often caused due to the excess withdrawal of groundwater that leads to the collapse of the surface. Similarly, the caves also form when the limestone(a rock) dissolves due to rainwater percolating CO2 through the soil which causes the reaction to take place. Thus, option B is the correct answer.
