Answer:
No, it cannot carry out photosynthesis because the plant will not be able to absorb light as it does not have chlorophyll.
Explaination:
Chlorophyll in plants is used for absorbing energy from light. And, in photosynthesis, light/sunlight is one of the main factors needed, so as the plant cannot absorb light, photosynthesis can't take place.

3. A strain of cells undergoes a mutation that increases the permeability of the inner
mitochondrial membrane to hydrogen ions.
a) What effect would you expect this mutation to have on the process of cellular
respiration? 12
b) Assuming the mutant cells can survive, how might the metabolic requirements of
these cells differ from those of a non-mutant strain of the same variety? 12
A mutation that involves the permeability of the inner mitochondrial membrane to protons (H+) will affect the amount of ATP. If mutant cells can survive, then they will need more energy to create a suitable gradient.
Cellular respiration is a series of metabolic reactions by which aerobic cells can generate energy in the form of ATP by using the chemical energy stored in the foods.
Cellular respiration can be divided into three sequential stages: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the inner mitochondrial membrane is coupled to the generation of an electrochemical proton (H+) gradient, which is then used to generate ATP by means of a protein complex known as ATP synthase.

A euglena is a unicellular organism. Choose an everyday object, such as a car, to use as a model of this euglena. Explain how the parts of the object model how the euglena's cell parts help it stay alive.
Answer:
a car:
Flagellum is a long thread-like structure that works as a navigator or a steering wheel in a car. The thin filament helps an euglena to move forward in any direction it desires.
Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.
The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.
Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.
The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.
Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.
Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off
Explanation:
The internal structures found in a typical photosynthetic Euglena are as follows:
Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape
Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment
Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles
Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis
Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins
Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source
Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins
Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell
Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes
Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins
Contractile Vacuole: It maintains the water and salt balance within the cell
Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water
Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming
Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma
Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis
Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.
The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.
What is Euglena?Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.
What is flagellum?Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.
With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.

When cells go through division in the early stages of life, they are known of stem cells. How do
we end up with all the different types of cells?
Answer:
these differentiate as a result of signaling mechanisms. ... The daughter cells divides and after each division it becomes more specialized. When it reaches a mature cell type downstream (for example, becomes a red blood cell) it will no longer divide.
Answer:
stem cells are called upon to generate a particular type of cell, they undergo asymmetric cell division.
Explanation:
with asymmetric division, each of the two resulting daughter cells has it's own unique life course
Why is it that cancer does not form every time there is a mistake during the cell cycle?
Answer:
Cells will actually kill themselves through a process called apoptosis, or it will be attacked and killed so it doesn’t spread. For example, when you are exposed to the sun for a long period of time, the solar radiation can mess with your skin cells. That’s why you get sunburned: the cells dry up and fall off. Otherwise, you could get skin cancer

A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?
Answer: Ancient Relative of a living organism
Explanation: Ancient Relative because by using the index fossil, you are also using the law of superposition. This law does not give you an accurate/specific date but instead the order they are in (i.e me saying i am older than my siblings compared to me saying i am 2 years older than them). By using an ancient relative of a living thing then we can see its phylogenic tree and measure around how old it is. Fossils also hold carbon and chemicals in there bones which allows us to use carbon dating. Carbon dating is an accurate way of measuring age.

Most of the world's iron ore, including that found in northern Minnesota, formed during the middle Precambrian period, ranging in age from 1.8 to 2.5 billion years old. They are composed of alternating layers of iron-rich material, most often magnetite or hematite, and silica. These iron oxide minerals formed on the ocean floor, creating the banded iron deposits you see here. What was the source of the oxygen that helped to produce these deposits?
A) The oxygen that was released into the atmosphere as a by-product of photosynthesis caused iron deposits to oxidize creating the iron oxide minerals.
B) Photosynthetic organisms making oxygen as a by-product of photosynthesis and the oxygen reacted with the iron dissolved in seawater to form iron oxide minerals.
C) The decomposition of carbon-based life forms in the oceans released oxygen and carbon dioxide. These gases reacted with the iron deposits forming the minerals mentioned.
