C4 plants differ from c3 and cam plants in that c4 plants____.
Answer:
The difference between C3, C4, and CAM photosynthesis is the way plants extract carbon dioxide from sunlight. This depends largely on the plant's habitat. C3 photosynthesis produces three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.
CAM plants open their stomata at night, C3, and C4 open during the day.

Describe the pressure changes that occur in the lungs during breathing for someone with emphysema
Answer:
Emphysema can lead to destruction of the alveoli, the tiny air sacs that allow oxygen to get into the blood. Their destruction leads to the formation of large air pockets in the lung called bullae. These bullae do not exchange oxygen and carbon dioxide like normal lung tissue. Also, the bullae can become very large.

In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.
What is Female reproductive organ?One ovary is located on either side of the uterus in the majority of females. They have two primary functions: generating hormones and releasing eggs. They are roughly the size and shape of an almond.
At birth, two ovaries each hold about 700,000 immature eggs, or oocytes (Trusted Source). These eggs start to grow and mature inside the ovary follicles after a person reaches puberty.
A developed egg is released by the ovaries around once every month. The menstrual cycle includes a process called ovulation, which is what gives rise to eggs.
Therefore, In this lab, you dissected a flower. The modified leaves that surround the reproductive parts are called petals. These structures help attract pollinators to the flower. The pistil is the female reproductive organ, which contains three segments: the stigma, style, and ovary.

Explanation:
It is not option (A) because it says that Lactobacillus is a kind of bacteria that harms you, not is good for you, and parasitic bacteria are harmful to you, so not (A).
Not (C) because it does not make any sense whatsoever.
Not (D) since that says that S. typhi has a mutualistic relationship, which is good for both organisms, which is not true in this case.
It is (B) because the harmful bacteria, S. typhi is a parasite to humans.
It is also (E) since that says that the Lactobacillus bacteria does share a good relationship with humans.

Plants have low energy needs as compared to animals. Explain.
➜ Plants do not move. In a large plant body there are many dead cells like schlerenchyma which provide strength to the plant but do not perform any cellular function. As a result they requires less energy. Animals, on the other hand, need energy for different activities like movement or search or food. So, they require more energy.
➥ Plants have low energy needs as compared to animals because they do not move. Moreover, in a large plant there are many dead cells like sclerenchyma because of which they also need less energy.

How does the gain or loss of thermal energy cause molecules to evaporate?
Answer:
When a liquid is heated, the molecules gain energy. This means they move and vibrate more, causing them to escape in the atmosphere.
The effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells is the same. However, due to the cell walls of plants, the visible effects differ. Although some effects can be seen, the rigid cell wall can hide the magnitude of what is going on inside.
Answer:
Yes.
Explanation:
Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.

Why does DNA need to be opened before mRNA
can be built?
Answer:
Since DNA contains recognition sites for RNA polymerase or its helper proteins to bind to, it must be opened before mRNA can be formed.The promoter region of the DNA opens up, allowing RNA polymerase to begin transcription. - gene (or, in bacteria, each transcribed group of genes) has its own promoter.Explanation:
DNA (Deoxyribonucleic acid )
DNA is a molecule made up of two polynucleotide chains that coil around each other to form a double helix and carry genetic instructions for the development, function, growth, and reproduction of all known organisms and viruses. DNA and ribonucleic acid are examples of nucleic acids (RNA).
Since they are made up of smaller monomeric units called nucleotides, the two DNA strands are known as polynucleotides. Each nucleotide is made up of a sugar called deoxyribose, a phosphate group, and one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).

How do scientists determine the absolute age of rocks and fossils?
Scientists determine the absolute age of rocks and fossils with the help of a method known as radiometric dating.
What are Fossils?Fossils may be defined as the dead and organic preserved traces of past living organisms that were buried deep onto the earth millions of years ago.
Radiometric dating is a methodology that is utilized in order to determine or estimate the age of an object on the basis of the concentration of a particular radioactive isotope that is significantly contained within it and the half-life of that isotope as well.
The main evidence for determining the absolute age comes from radiometric dating methods, such as carbon-14 dating. Such types of methods depend on radioactive decay.
Therefore, the radioactive dating method is one of the methods through which scientists determine the absolute age of rocks and fossils.
