What will happen if homogenisation and pasteurization steps are omitted during the production of yoghurt is:
There will be presence of harmful bacteriaThere will be a non uniform textureHomogenisation is the process of making two liquids become the same and that they do not separate. For example, during the production of milk, fat droplets are combined so that the cream does not break apart.The main aim of homogenisation is to make two soluble liquids uniform and combine and have similar texture.Pasteurization is the process of heating products, which can either be liquid or solid so that the harmful microorganisms and bacteria are removed. This is done to prevent spoilage and for preservation.The main aim of pasteurization is to eliminate pathogens and for preservation.Read more here:

Imagine you discover a new species of primate. It has a medium body size (about 35 lbs.), wide incisors, and molars with low and rounded cusps. Based on this information only, what can you hypothesize about this new species' behavior and ecology? A. It is probably a follore B. It is probably an faunivore C. It is probably an insectivore. D. It is probably afrugivore
Answer:
D. It is probably a frugivore
Explanation:
A frugivore is an herbivore or omnivore that prefers to eat fruit, although they may also eat seeds, roots, leaves, etc. It has been proposed that humans evolved from tree-dwelling frugivores. The dental characteristics of the frugivorous primates include large incisors, as well as low and rounded cusps (referred to as bunodont molars). Moreover, frugivorous primates also include the entire spectrum of body sizes.

Which planet(s) in the solar system has/have retrograde orbits around the Sun?
Answer:
As viewed from a position in space north of the solar system (from some great distance above the Earth's North Pole), all the major planets revolve counterclockwise around the Sun, and all but Venus and Uranus rotate counterclockwise on their own axes; these two, therefore, have retrograde rotation.
Explanation:
got it from google hope it helps
Answer Choices:
O Earth, Mars, and Saturn
● Venus and Uranus
O Uranus
O Jupiter
Explanation:
Venus and Uranus rotate clockwise when viewed from the north pole of the sun, while the sun spins counterclockwise. This difference in the rotational and orbital directions is defined as retrograde motion.

Answer:
5g/cm³
Explanation:
Given parameters:
Mass of the metal = 10g
Volume of the metal = 2cm³
Unknown:
Density of the metal = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Insert the parameters and solve;
Density = [tex]\frac{10}{2}[/tex] = 5g/cm³

Which among the following options is a disorder in the environment?
a. A basket of unwashed dirty clothes b. A house with no single plant
c. A garden with dying plants d. A library with a small number of books
Answer:
B. A house with no single plant
A garden with dying plants is a disorder in the environment (Option c).
Homeostasis refers to the biological processes by which organisms maintain a state of internal equilibrium independent of the environment's state (i.e. their internal conditions are relatively stable).
In biology, the disorder is associated with a lack of homeostasis.
In plants, disorders are associated with different non-pathological conditions (e.g., lack of macronutrients, poor light conditions, etc). These environmental conditions may lead to the death of the plant.
In conclusion, a garden with dying plants is a disorder in the environment (Option c).

Two factors that affect human sleep patterns are the time of day and level of melatonin, a chemical found in one's body. For example, as the Sun goes down at night, the body knows it is time to go to sleep. Similarly, when a person's level of melatonin changes, they can become alert or sleepy. Using this information, how could these stimuli be described?
A. Hours of sunlight per day and melatonin levels are both Internal stimuli.
B. Hours of sunlight per day and melatonin levels are both external stimull.
C. Hours of sunlight per day is an external stimulus, while the level of melatonin in a person is an internal stimulus.
D. Hours of sunlight per day is an internal stimulus, while the level of melatonin in a person is an external stimulus.
E. Hours of sunlight per day and melatonin levels are both internal and external stimuli.
Answer:
C. Hours of sunlight per day is an external stimulus, while the level of melatonin in a person is an internal stimulus.
Explanation:

Compare and contrast the main characteristics of the alpine and taiga biomes.
Answer:
Both the alpine and taiga biomes have two distinct seasons. The alpine biome is found on five of the seven continents, while the taiga biome is found on three. The alpine biome gets an average of 12 inches of precipitation annually and the taiga biome gets an average of 12-33 inches annually. Both the alpine and taiga biomes have cold winters with temperatures below freezing and warmer summers. The taiga biome has a greater average temperature range in the summer than does the alpine biome.
Explanation:
There are two separate seasons in both the taiga and alpine biomes. Taiga biomes are only present on three of the seven continents, compared to five for alpine biomes.
What are alpine and taiga biomes?Precipitation averages 12 inches per year for the alpine biome and 12 to 33 inches per year for the taiga ecosystem. Both the alpine and taiga biomes have warmer summers and extremely harsh winters with temperatures below zero.
Similar to the tundra, the taiga has extremely chilly weather. Additionally, it experiences extremely long winters and incredibly brief, warm summers. Although it doesn't get much rain, it usually gets more than the tundra. However, the soil is still very deficient.
Conifers make up the majority of the local life. Because of their cone form, which allows snow to fall off of them, their dark hue, which allows them to absorb thermal energy, and their needles, which help minimize water loss, conifers do well in this habitat.
Therefore, There are two separate seasons in both the taiga and alpine biomes. Taiga biomes are only present on three of the seven continents, compared to five for alpine biomes.

Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
It includes two earth system - the biosphere and the atmosphere.
Explanation:
The carbon cycle is the cycle or series of actions that move the carbon through various earth systems. The recycling of the carbon in the pathway includes the biosphere which interacts with the atmosphere as it pulls and releases the carbon in the form of carbon dioxide by two cellular processes known as photosynthesis (only in algae and plants) and cellular respiration.
Photosynthesis is the process that pulls the carbon dioxide for the production of sugar and oxygen with the help of light energy in plants (biosphere) from the atmosphere.
Photosynthesis helps to transfer carbon to the biosphere and the atmosphere.
It should be noted that the carbon cycle refers to the cycle that moves carbon through various earth systems. Photosynthesis helps to transfer carbon to the biosphere and the atmosphere.
Also, the recycling of the carbon in the pathway includes the biosphere where carbon is released in the form of carbon dioxide through photosynthesis and cellular respiration. Photosynthesis pulls the carbon dioxide for the production of sugar and oxygen.
