In an early experiment, it was found that a mouse in a sealed glass jar soon died, but if a plant was included in the jar, the mouse lived much longer. Explain theses results.
Answer:
The correct answer is - mouse produces carbon dioxide which is used by the plants for photosynthesis that in turn produces oxygen that is used for cellular respiration.
Explanation:
A mouse can not live in a sealed container or jar for a long time whereas with a plant in a closed and sealed jar mouse can live longer. This is due to the fact that in absence of the plant there is no oxygen for the mouse to get perform cellular respiration.
in a jar with a plant, the mouse lives longer because the plant still produces oxygen by the process of photosynthesis which is used by the mouse for cellular respiration and produces carbon dioxide that is taken by the plant.

POST-lab Question:
What would be the effect on the butterfly population if the coloration in the environment suddenly changed? (Example: green
butterflies are living on a green plant that suddenly turns brown and loses all its leaves).
Answer:
The butterfly population would decrease or die out.
Explanation:
If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Changes in ____ result in a change in protein structure which alters the ____-type of the organism and MIGHT increase _____.
Answer:
DNA, genotype and resistance.
Explanation:
Change in DNA of an organism results in a change in the shape and structure of protein because DNA has the codes of instructions on the basis of which ribosomes synthesis proteins for the cell. This change occurs due to mutation in the DNA sequence that causes change in protein. Due to this mutation, the genotype of an organism changes and might increases its resistance that leads to its survival in that environment so we can say that mutation has good effects on the organisms.

Explanation:
What would happen to a population if all females reproduce through parthenogenesis alone?
Answer:
All the offspring from parthenogenesis are female. So if the female stick insects carry on reproducing alone, the males could be wiped out. ... This may help explain why parthenogenesis remains rare, even in species that are capable of it. In such species, "males typically force females to mate".

The diagram below shows two processes, P and Q, in the carbon cycle.
Which of these statements best describes the processes P and Q?
P shows diffusion and Q shows weathering.
P shows weathering and Q shows diffusion.
P represents combustion and Q represents decomposition.
P represents decomposition and Q represents combustion.
Answer:
P shows diffusion and Q shows weathering.
Explanation:
The process shown in the image attached to this question is a part of the carbon cycle. Based on the image in this question, atmospheric carbon enters the ocean in a process called P while carbon deposited in limestone is released into the atmosphere via a process called Q.
- Atmospheric carbon which is carbon dioxide (CO2) enters the surface of the ocean via a process called DIFFUSION, hence, process P shows diffusion
- Also, for the carbon in limestone to be released into the atmosphere, the limestone has to be broken down in a process called WEATHERING. Hence, process Q shows weathering.

There a four shared features of Chordates. Match the feature with the appropriate characteristic or function. Group of answer choices found between the digestive tract and nerve cord [ Choose ] in some embryos this develops into the central nervous system [ Choose ] in invertebrate chordates can be involved in filter food from water ingest through the mouth [ Choose ] in jawed fish this provides support for the jaw [ Choose ] provides skeletal support [ Choose ] is derived from the ectoderm
Answer:
1. Notochord.
2. Dorsal hollow nerve cord.
3. Pharyngeal slits.
4. Pharyngeal slits.
5. Notochord.
6. Dorsal hollow nerve cord.
Explanation:
A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.
A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.
The four (4) shared anatomical features or characteristics of chordates includes the following;
1. Notochord: found between the digestive tract and nerve cord.
2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.
3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.
4. Pharyngeal slits: in jawed fish this provides support for the jaw.
5. Notochord: provides skeletal support.
6. Dorsal hollow nerve cord: is derived from the ectoderm.

Bacteria are capable of
reproducing quickly. Explain how
this adaptation is beneficial in
their ability to become resistant
to antibiotics
Answer:
Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.
The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.
Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

What is stored energy and where is it in the food chain?
Answer:
At each level in a food chain, some energy is stored in newly made chemical structures, but most is dissipated into the environment. Continual input of energy, mostly from sunlight, keeps the process going. 3.4 Energy flows through food webs in one direction, from producers to consumers and decomposers.
