Active and passive transport are cellular processes that involve the transport of substances inside and outside the cells.
Active and passive transport help the cell to regulate the uptake and removal of materials (Option D is correct).Passive transport is a type of transport that does not involve an energy input to transport substances in favor of a concentration gradient.There are four main classes of passive transport:filtrationosmosissimple diffusionfacilitated diffusionActive transport is a type of transport that requires energy to move substances against a concentration gradient.Learn more in:

Can you observe cells with the naked eye? Explain.
Answer:
No
Explanation:
According to science, human beings can't observe cells and other tiny organisms with our naked eyes coz our eyes aren't strong enough to observe but we can use a microscope which has strong lenses.
As cell is a tiny microscopic structure, it can be visible under microscope only.
what are the types of cell ?Cell is the basic unit of any living organism, can be observed in animal, plant, microbes etc; Bacteria are unicellular in nature, all higher eukaryotic organisms are multicellular in nature like plants and animal cell.
The simplest type of cells are prokaryotic cells have a cell membrane, cytoplasm where all of the metabolic processes occur, ribosomes where protein synthesis occur, and nucleoid which carry genetic information, reproduce by binary fission.
The eukaryotic cells have cell membranes, cytoplasm, ribosomes, and nucleus a house of DNA, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.
It has mitochondria energy house, a cytoskeleton for structure and passes information, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.

blank makes up cell membranes
Phospholipids : This makes up the bi-layer which is the membrane's basic structure and has great control over what can enter and exit the cell, due to their hydrophobic tails and hydrophilic heads.
Cholesterol : This also controls entry and exit of substances as it also exhibits hydrophilic heads and hydrophobic tails. It also stabilises the membrane and affects its fluidity (the more there is, the more fluid is the membrane.)
Glycolipids : Those can act as receptor molecules (essential for cell-signalling), antigens and in cell-adhesion
Answer:
glycerophospholipids
Explanation:
With few exceptions, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

A. theory
B. observation
C. question or problem statement
D. hypothesis
A research question is the basis of the experimental analysis of the subject matter. A hypothesis is said to be the potential solution to a research question. Thus, option D is correct.
What is a hypothesis?The hypothesis has been defined as the supposition that acts as the basis of the research and experiment and has been constituted of some evidence and facts to formulate the research question.
It acts as a starting point for any investigation and research and must be falsifiable. They should be testable in order to determine the verifiability of the research topic. If the tested hypothesis is correct then further research is conducted.
It can also be defined as an educated guess that is based on some prior knowledge and facts that are deduced through experiments.
Therefore, the hypothesis is a potential solution.

Certain traits, such as color blindness, are determined by an X-linked recessive gene. A couple in which both have normal vision have a color-blind son. The probability of this couple having a daughter who is a carrier is
Answer:
A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
Explanation:
If a woman has only one color blind ‘gene’ she is known as a ‘carrier’ but she won’t be color blind. When she has a child she will give one of her X chromosomes to the child. If she gives the X chromosome with the color blindness ‘gene’ to her son he will be color blind, but if he receives the X chromosome which doesn’t carry the color blindness ‘gene’, he won’t be color blind.
A color blind boy can’t receive a color blind ‘gene’ from his father, even if his father is color blind, because his father can only pass an X chromosome to his daughters.
A color blind daughter therefore must have a father who is color blind and a mother who is a carrier (who has also passed the color blindness ‘gene’ to her daughter). If her father is not color blind, a ‘carrier’ daughter won’t be color blind. A daughter can become a carrier in one of two ways – she can acquire the ‘gene’ from a carrier mother or from a color blind father.
