How do CAM plants fix carbon?
Answer:
CAM plants temporally separate carbon fixation and the Calvin cycle. Carbon dioxide diffuses into leaves during the night (when stomata are open) and is fixed into oxaloacetate by PEP carboxylase, which attaches the carbon dioxide to the three-carbon molecule PEP.

Describe what happens during each phase
of mitosis:
· Prophase:
· Metaphase:
· Anaphase:
· Telophase:
Answer:
I KNOW THIS
In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
Explanation:
Answer:
Explanation:
Prophase- During this phase the genetic material inside the nucleus condenses an the duplicated chromosomes become visible. Outside the nucleus, a spindle starts to form.
Metaphase- During this phase the centromeres of the duplicated chromosomes line up across the center of the cell. Spindle fibers connect the centromere of each chromosome to the two poles of the spindle.
Anaphase- During this phase the chromosomes separate and move along spindle fibers to opposite ends if the cell.
Telophase- During this phase the chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin.
How does the body obtain glucose?
Answer:
When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
Answer:
By breaking down and synthesising carbohydrates
Explanation:
When the mouth consumes starch contained or carbohydrate foods, and it passes through the oesophagus to the stomach, starch enzymes are released to break down the complex sugars to a simpler monossacharide sugar called glucose.

Explain at least three ways in which a mutation in an individual's DNA could occur, and describe at least 2 effects a mutation could have on an individual's traits.
Answer:
Explanation:
Three ways in which mutation could occur are
1) If an error occurs during DNA replication and it's not corrected in time by DNA polymerase.
2) If there is a deletion of a base(s) in the sequence of the DNA. The deletion of a DNA nucleotide/base could also cause a mutation as that could affect the formation of an enzyme or protein useful in building and/processing certain body parts/processes.
3) Thymine dimerization: Thymine dimers are mutations that prevent DNA from replication or even transcription hence preventing a cell from undergoing division (hence causes cancer). They are formed when covalent bonds are formed between the bases of a DNA sequence (somewhere around the carbon-carbon double bond).
The two effects are
1) It could cause cancer as described in (3) above (in the case of thymine dimer)
2) It could lead to deformity in an individual because of the gene that is supposed to code for the last finger has a base deletion, that could eventually lead to the absence of that finger or a shorter or "strange" finger.
Which is the correct chemical equation for photosynthesis?
A.) 6CO₂ + 6H₂O ® C₆H₁₂O₆ + 6O₂
B.) C₆H₁₂O₆ + 6O₂ ® 6CO₂ + 6H₂O
C.) 3CO₂ + 3H₂O + 3O₂ ® C₆H₁₂O₆
D.) 6O₂ + 6H₂O ® C₆H₁₂O₆ + 6CO₂
6CO₂ + 6H₂O ® C₆H₁₂O₆ + 6O₂ is the correct chemical equation for photosynthesis. Therefore, the correct statement is option A.
What is Photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce organic compounds and oxygen. The process of photosynthesis involves two main stages: light-dependent reactions and light-independent reactions. The chemical equation for photosynthesis is: 6CO₂ + 6H₂O ® C₆H₁₂O₆ + 6O₂
The above equation represents the combination of six molecules of carbon dioxide and six molecules of water in the presence of sunlight to produce one molecule of glucose and six molecules of oxygen.
During light-dependent reactions, light energy is absorbed by chlorophyll molecules to generate ATP and NADPH and in light-independent reactions, ATP and NADPH are used to convert carbon dioxide into organic compounds, such as glucose.
Therefore, 6CO₂ + 6H₂O ® C₆H₁₂O₆ + 6O₂ is the chemical equation for photosynthesis.

Answer:
THE SATELLITES OF URANUS!!
Explanation:
The other answer was WRONG! One of the satellites of Pluto has an orbit like the satellites of Uranus.
Here is a quote from my textbook:
Therefore, the moon remains over one side of Pluto all the time and can never be seen from the other side of Pluto. Like the satellites of Uranus, Charon's orbit is perpendicular to Pluto's orbital plane.

Answer:
Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
Explanation:
A species' ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population a more simple definition is if two species have the same niche, one species will exclude the other.

11. Centrioles, asters, and spindles are mitotic structures responsible for pulling apart the sister chromatids.
12.The centriole
Explanation:
Centrioles, asters, and spindles are mitotic structures responsible for pulling apart the sister chromatids during meiosis. The centriole anchors the spindle.
What are sister chromatids?One of a chromosome's two identical halves that has been replicated in preparation for cell division is known as a chromatid. The centromere, a constrictive area of the chromosome, is where the two "sister" chromatids are linked.
Spindle fibers that are attached to the centromere pull the sister chromatids to the opposing sides of the cell during cell division. The cell divides into two shortly after, producing daughter cells with the same DNA.
Anaphase begins with the division of sister chromatids, which is followed by the movement of the chromosomes toward the spindle poles.
Therefore, Centrioles, asters, and spindles are mitotic structures responsible for pulling apart the sister chromatids during meiosis. The centriole anchors the spindle.
