Answer: 1Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive. 2Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. 3In passive transport, substances simply move from an area of higher concentration to an area of lower concentration, which does not require the input of energy. Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. 4In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.5: Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. ... Water has a concentration gradient in this system. Thus, water will diffuse down its concentration gradient, crossing the membrane to the side where it is less concentrated. 6Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. 7In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.8During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.9Endocytosis definition and purposes. Endocytosis is the process by which cells take in substances from outside of the cell by engulfing them in a vesicle. ... Endocytosis occurs when a portion of the cell membrane folds in on itself, encircling extracellular fluid and various molecules or microorganisms.10Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell, as shown in Figure below. Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin

what would happen if homogenisation and pasteurisation steps are omitted during the production of yoghurt
Answer:
The correct answer would be - there could be microorganisms like bacteria present and consistency or texture would be not as expected.
Explanation:
Pasteurization is more of a safety process that helps in the elimination of microorganisms like bacteria and this process involves heating the liquid and cooling it down immediately to a very low temperature.
Homgenisation is the process that makes liquid particles evenly small and distributed equally which gives it consistency or texture and taste. Without these two processes, yogurt will have bacteria and inconsistency.

What are the two units of measure
Answer:
hope this helped:)
Explanation:
Systems of Measurement: there are two main systems of measurement in the world: the Metric (or decimal) system and the US standard system. In each system, there are different units for measuring things like volume and mass.
There are many different units of measurement that apply to different quantities and variables. However, if we are talking about the most basic units of measurement of the International System of Units (SI), they are:
1. The unit of measurement of length or distance is meter (m). It is often used to measure the size or dimensions of an object.
2. The unit of measurement of mass is the kilogram (kg). It is used to determine how much material is present in an object.
Other derived units of the SI system, such as the second for time, the liter for volume, and the newton for force, are all derived from these two basic units: the meter and the kilogram.

B.Cytoplasm from the parent cell becomes two daughter cells.
C.The cell takes a rest.
D.The genetic material of the parent cell multiplies into four sets
Answer:
A. The cell grows and makes a copy of its genetic materialExplanation:
Before Mitosis, is a stage in the cell cycle called the 'Interphase'. During Interphase, the cell grows and makes a copy of its genetic material. During the G1 phase, the cell grows. During S phase, the cell's DNA replicates itself. And during G2, the cell grows and prepares for cell division (mitosis)
Which level of taxonomy divides its organisms based on DNA sequences
instead of structural similarities? *
A Domain
B Kingdom
C Genus
O D Species
Answer:
D Species
Explanation:
Living organisms have been organized into groups using the Kingdom to Species classification. Kingdom level represents the least specific while Species level represents the most specific. Prior to the discovery of DNA, classification of organisms has been based on structural similarities i.e. organisms that look similar are classified into the same species.
However, the discovery of DNA, put a stop to the erroneous classification of organisms based on structural similarities as there were many exceptions to this. Since members of the same species have a nearly identical DNA, it is used to divide its organisms based on DNA sequences
instead of structural similarities.
How do naturally occurring hormones affect plants? They ripen fruits, prevent plants from being eaten by insects, and help plants collect water from soil. They start lateral leaf growth, help plants collect water from soil, and speed up the growth of plant cells. They keep buds inactive in winter, speed up the growth of plant cells, and ripen fruits. They speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects.
Answer:
c
Explanation:
Naturally occurring hormones affect plants as they speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects, which is the last option.
What is a plant hormone?Naturally occurring hormones in plants, also known as plant growth regulators, play a crucial role in regulating various physiological processes in plants. There are five main types of plant hormones: auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Each of these hormones affects plant growth and development in different ways. Auxins, for example, are primarily responsible for cell elongation and the promotion of lateral growth in shoots. They also play a role in root growth and phototropism, which is the movement of plants towards or away from light sources.
Hence, naturally occurring hormones affect plants as they speed up the growth of plant cells, ripen fruits, and prevent plants from being eaten by insects, which is the last option.

- I would not give this definition on the exam)
Answer:
Answer:
The seven characteristics that Mendel evaluated in his pea plants were each expressed as one of two versions, or traits. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring. We now call those two copies genes, which are carried on chromosomes. The reason we have two copies of each gene is that we inherit one from each parent. In fact, it is the chromosomes we inherit and the two copies of each gene are located on paired chromosomes. Recall that in meiosis these chromosomes are separated out into haploid gametes. This separation, or segregation, of the homologous chromosomes means also that only one of the copies of the gene gets moved into a gamete. The offspring are formed when that gamete unites with one from another parent and the two copies of each gene (and chromosome) are restored.
