Pathogens can be transmitted by air, blood, droplet, and direct contact.
Pathogens are microorganisms that can cause diseases. Bacteria, fungi, viruses, protozoa, and prions are the five main types of pathogens.
Pathogens can be transmitted as follows:
Airborne: In this transmission path, the pathogenic infections are transferred through coughing, sneezing, or talking. They can also spread through dust particles containing microorganisms.Bloodborne: Here, the pathogens are transmitted through saliva, sexual contact, sweat, or injuries.Droplet: Droplets that are spread through coughs, sneezes, or other actions might transmit infection from person to person. Sprays and splashes happen when germs are dispersed through droplets and touch the mouth, nose, or eyes of a vulnerable person.Direct contact: Pathogens are spread through direct contact with bodily fluids, skin, or mucous membranes of the infected individual.To read more about pathogens visit:

How to explain the tongue?
The food enters the mouth passing the TOT (tip) of the tongue. It is moved around by the motion of the tongue and teeth as the food is chewed. Its movement is facilitated by the taste buds on the tongue which are jagged, aiding in their ability to move food.
Fungiform papillae on the side of the tongue and filiform papillae located on the dorsal surface of the tongue come in contact with the tastant.
Both types of papillae have taste buds that have receptors for individual tastes -sweet, sour, salty umami (savory), and bitter. Once a tastant is bound to the receptor it creates a signal that travels through one of the three carnival nerves depending on the location of the taste buds. For taste buds located on the front of the tongue, the signal travels through the facial nerve.
For taste buds located in the middle of the back of the tongue, signals travel through the glossopharyngeal nerve. The signals travel to the nucleus of the solitary tract of the brainstem, where they are relayed to the thalamus for higher processing.

The water molecule is a polar molecule. A water molecule is polar because
The electrons are shared equally
Oxygen has a stronger attraction for electrons than hydrogen
It is very cold
Hydrogen atoms have a stronger attraction for electrons than oxygen
Answers
The correct answer is: "B. Oxygen has a stronger attraction for electrons than hydrogen."
What are polar molecules?A water molecule is polar because it has a bent shape and an unequal sharing of electrons between the oxygen and hydrogen atoms.
Oxygen has a stronger electronegativity (ability to attract electrons) than hydrogen, which means it attracts the shared electrons in the covalent bond between the two atoms more strongly. As a result, oxygen has a partial negative charge (δ-) and hydrogen has a partial positive charge (δ+).
This separation of charges makes the water molecule polar, with a slightly negative end and a slightly positive end. This polarity allows water molecules to interact with each other through hydrogen bonding and gives water its unique properties, such as its high boiling point, surface tension, and solvent abilities.

Advantages of seed development
Answers
Answer:
The advantages of seed development include increased crop yields, improved disease resistance, and enhanced nutritional content.
Seed development in plants provides several advantages, including protection and dispersal of offspring, dormancy for survival in unfavorable conditions, and a nutrient-rich food source for germination and early growth.
Seed development in plants offers various advantages that contribute to their reproductive success and survival.
One key advantage is the protection and dispersal of offspring. Seeds are enclosed within a protective seed coat, which shields the embryo from external threats such as desiccation, mechanical damage, and predation. Additionally, seeds have adaptations for dispersal, allowing them to spread over a wider range and colonize new habitats.Another advantage is dormancy. Seeds can enter a state of dormancy, remaining inactive until conditions become favorable for germination and growth.This allows plants to survive through periods of unfavorable environmental conditions such as drought, extreme temperatures, or lack of sunlight. Dormancy also enables seeds to delay germination until suitable resources and conditions for growth are available.
Furthermore, seeds serve as a nutrient-rich food source for the developing embryo. They contain stored reserves of carbohydrates, proteins, and lipids that provide energy and nutrients for germination and early growth when the seedling is not yet photosynthetically active.In summary, seed development in plants provides advantages such as protection and dispersal of offspring, dormancy for survival during unfavorable conditions, and a nutrient supply for early growth and development. These traits contribute to the reproductive success and resilience of plants in diverse environments.

Answers
The correct statement about Australia is ; It experiences the first day of summer at Position 1 and first day of winter at Position 3.
The southern and northern hemisphere experiences winter and summer at different times of the year because the Earth's axis remains fixed ( almost ) when it orbits around the sun. therefore during the different orbit phases either the northern hemisphere or southern hemisphere faces/leans towards the sun.
The part of the earth ( hemisphere) that faces the sun will experience its first day of Summer while the hemisphere that leans away from the sun will experience its first day of winter.
Hence from the diagram we conclude that Australia been in the southern hemisphere will experiences the first day of summer at Position 1 and first day of winter at Position 3.

A certain lake has a volume of about 480 m³. If the total population of freshwater shrimp in the lake is 600 million, what is the population density of the shrimp in that lake?
Answers
Answer:
1,250,000 shrimps per m³
Explanation:
Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;
Population density = population (N)/volume
According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;
Population density of the lake = population of shrimps ÷ volume of lake
Population density = 600,000,000 ÷ 480
Population density = 1,250,000 shrimps per m³

Answers
Answer:
1. The true statement about the relationship between an organism's traits and its genes is that genes encode the proteins that determine an organism's traits (option B).
2. A DNA mutation can cause the structure of the protein to be changed (option C).
Explanation:
DNA contains the genetic information necessary for the structure and function of living beings. It is a molecule that, once transcribed into mRNA, dictates the rules for protein synthesis.
1. Chromosomes are composed of a DNA molecule, whose segments form the genes that contain specific base sequences to determine a trait.
The information from the DNA is transcribed into the mRNA, which is responsible for carrying it to the cytoplasm where protein synthesis occurs. These proteins formed from the genetic code determine the different traits in living beings. So, genes encode the proteins that determine an organism's traits.
2. Since the DNA contains the information needed to transcribe it into the mRNA and for the mRNA to initiate protein synthesis, any alteration in the DNA base sequence -due to mutation- can be produced:
A transcription of the mRNA with the alteration That during mRNA translation, the codon that forms an amino acid, or that determines the stop of protein synthesis, is changed. The alteration or change, consequently, of the synthesized protein.There is a relationship between the DNA mutation and the structure of the protein being changed.

Two features that show that the structures are possessed by humans are the presence of four-chambered hearts and the existence of a closed circulatory system. The four-chambered heart in humans allows for efficient separation of oxygenated and deoxygenated blood, ensuring that oxygenated blood is supplied to the body's tissues. The closed circulatory system in humans ensures that blood is transported within blood vessels, preventing blood from coming into direct contact with other body tissues and organs. This system allows for the efficient transport of oxygen and nutrients to the body's tissues, while also removing waste products such as carbon dioxide.
