5. Could producers survive without consumers? Why or why not?
Answers
Explanation:
Autotroph are known as producers
(2) Autotroph: An organism capable of synthesizing its own food from non-living substances using light or chemical energy.
(3) Consumer: An organism that eats other organisms
(4) Heterotroph: Organisms that obtain its food and energy by taking in living or once living material, usually plant or animal matter.
(5) Chemosynthesis: Process by which some organisms, such as certai (1) Producer: An organism that makes it's own food it is the first Link any food chain[ green plants]
(2) Autotroph: An organism capable of synthesizing its own food from non-living substances using light or chemical energy.
(3) Consumer: An organism that eats other organisms
(4) Heterotroph: Organisms that obtain its food and energy by taking in living or once living material, usually plant or animal matter.
(5) Chemosynthesis: Process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates
(6) Photosynthesis: A process plants use to turn sunlight into food
How does the stability on an ecosystem depend on its producers?
they provide the basis for an ecosystems energy
What are the two processes used by producers to obtain energy?
photosynthesis and chemosynthesis
Few producers live deep below a lakes surface, suggest an explanation for this pattern
since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive
Could producers survive without consumers?
without consumers, there would be too many producers and they would all compete with each other until they died out

How is mRNA or protein synthesis in general related to communication?
Answers
Answer:Three general classes of RNA molecules are involved in expressing the genes encoded within a cell's DNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

How does water behave when it freezes?
Answers
Answer:
During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.

Dr. Kettlewelll predicted that clean forests would have _____________ colored moths, and polluted forests would have _________ colored moths.
Answers
Answer:
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
Dr. Kettlewall predicted that clean forests would have light-colored moths and polluted forests would have dark-colored moths. This is an example of natural selection.
What is natural selection?Natural selection is a phenomenon in which the fittest individual is chosen by nature. The animal can live and reproduce in that particular environment. An example is the peppered moth population.
The light-colored moths were found on the light-coloured bark, but their population started to decline after the pollution. In the polluted environment, they were easily chosen by predators. So only dark moths survived because they blended in with the polluted environment.
Following the end of the pollution, light colored moth increased again. Predators had a difficult time identifying the light moth because it blended in with the unpolluted environment. Hence, their population increases in unpolluted areas.
Hence, Dr. Kettlewall predicted that a clean forest would have a light-colored moth and a polluted forest would have a dark-colored moth.

A scientist investigates two types of cells located in different parts in the
human body. Cell A contains many more mitochondria than Cell B. What is
the best conclusion to make from this observation?
o O
A. Cell A produces more protein than Cell B
O
B. Cell A has a larger vacuole than Cell B.
C. Cell B does less work than Cell A.
O
D. Cell B creates more energy than Cell A.
Answers
Answer:
The best explanation regarding the observation of more mitochondria in cell A than in cell B is that cell B does less work than Cell A.
Explanation:
Mitochondria are the organelles in charge of energy production in the cell. Tissues with high energy demand, such as striated muscle, have cells with a large amount of mitochondria, to satisfy this requirement.
According to the observation, if the cell B has less work than the A cell, its energetic demand is lower and the consequence is a smaller quantity of mitochondria in its cytoplasm.
The other options are not correct because:
A and B. The fact that the A cell has more mitochondria is not related to protein synthesis or having larger vacuoles.
D. Cell B does not produce more energy than Cell B because it has fewer mitochondria.

Answers
Answer:
It might not work as efficiently because the conditions are different
Explanation:
The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.
Lori is a vegan who believes she gets all the nutrients she needs from her diet. She has never taken supplements, even when she was pregnant.

Answer:
The condition is called "Spinal Bifida", caused by lack of vitamin B12 which helps regenerate the active form of folate.
Explanation:
Because Lori is a vegan, her vitamin B12 intake which comes from animal products such as meat, is not enough. She has to take supplements to make up for the lack of it in her diet.
As stated in the question, this lack of vitamin B12 causes her child to have a defect in his spinal cord called Spinal Bifida that defines a spinal cord or spine that has not fully developed. The vitamin B12 is necessary for regenerating the active form of folate.

A
animalia
B
protista
C
bacteria
D
fungi
Answers
Answer:
B protista
Explanation:
The cell is unicellular, so it can not be an animal, which are all multicellular.
It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)
The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs
Therefore, the organism must be a protist, so the answer is B, protista.

What are the five categories of adaptations?
Answers
The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.
What is migration?The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
