Answer:
Because malfunctioning mitochondria disrupts the body's equilibrium, there is a strong link between homeostasis,
defective mitochondria, and the symptoms induced by
LHON.
The condition of homeostasis in the body was also
affected by symptoms caused by Leber's hereditary optic

Sara is learning about photosynthesis and cellular respiration in her science class. Which statement can Sara write that best explains the relationship between
these two processes?
O A. The chemical reactions of photosynthesis and cellular respiration could not take place without each other.
B. Photosynthesis and cellular respiration are chemical processes used in both animal and plant cells.
C. Plants use photosynthesis to produce food, while animals use cellular respiration to consume their food,
D. When cells do not have enough energy for respiration, they rely on photosynthesis.
oh
Answer:
The most suitable answer is C.
Explanation:
Photosynthesis is the process whereby plants manufacture their own food using water, carbon (iv) oxide and some other minerals in the presence of sunlight while cellular respiration is the oxidation (or breakdown) of substances in the mitochondria (site of cellular respiration) in living cells.

Land plants evolved long before any animals appeared on Earth. When they came onto land, they needed ways to keep from losing water, to reach the sun, and to produce oxygen. They started to convert the atmosphere from carbon dioxide to oxygen. Which of these is believed to be the common ancestor of land plants?
A. oak trees, because they are the dominant species in many areas
B. rose bushes, because they produce a sweet-smelling aroma
C. grass, because there is so much of it found on the land
D. green algae, because they use the same photosynthetic pigments as land plants

How do wales differ from fish
Answer:
Whales are mammals that need air from the sea's surface to survive. Whales are capable of giving birth to live young. Fish have gills and use them to draw oxygen from the water. The majority of fish lay eggs. Whales and other marine animals with horizontal tail fins, such as dolphins, have vertical tail fins, while fish have vertical tail fins.

Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?
Answer: The energy of the molecules in the hockey puck decreases.
Explanation:
When the temperature of the hockey puck decreases, then the energy of the molecules in the hockey puck decreases as well.
In this scenario, when the temperature of the hockey puck decreases, then the hockey puck will gain heat molecules and the cold energy of the molecules that are in the hockey puck will reduce.

Why does the author include the example of the Virginia northern flying squirrel?
To highlight the diversity of wildlife in the region
To contrast it with other more common species of squirrel
To demonstrate that protecting endangered species can be effective
To emphasize the importance of this species of squirrel in the ecosystem
Answer: The correct answer is To demonstrate that protecting endangered species can be effective
Explanation: The Unit text pointed out how the flying squirrel population had risen from 10 to over 1100, taking it off the endangered species list and proving that the methods were effective.
Because there are three different possible reading frames in a messenger RNA (mRNA) molecule, most mRNAs can be translated in a cell into three different proteins. true false
Answer:
False
Explanation:
In the genetic code, each triplet of nucleotides (i.e., each codon) determines one specific amino acid or one-stop codon. The genetic code is not overlapping, which means that the same letter in the genetic code (nucleotide) cannot be used for two different codons. There are 64 possible combinations of triplets of nucleotides, 61 of them determine amino acids, while three triplets determine stop codons (UAG, UAA, and UGA) that indicate the termination of translation. Moreover, the genetic code is also degenerate, which means that one amino acid can be coded by more than one codon.
Three genes (A, B, and C) are located on different chromosomes. In a cross between
AaBCC and AabbCc (P generation) what would be the probability of seeing an
offspring with the genotype AAbbCc in the Fı generation (assuming no linkage)?
Answer:
b, a, c
Explanation:
Since recombination frequency is directly proportional to the distance between genes, the values are used to locate genes on a chromosome. Here three genes a, b and c can assume any of three linear sequences: a-b-c or a-c-b or b-a-c, which depends on the gene present in the middle. Here, recombination frequency for a and b (X) = 20%, that for a and c (Y) = 8% and for b and c (Z) =28%. As we can see that Z = X + Y or 28 = 20+8 which means that genes b and c are present at extremes and a is in the middle. Thus, the sequence of genes is b-a-c.

The nucleus is surrounded by a semipermeable membrane. What would happen if this layer were permeable to most substances?
A. The DNA in the nucleus would be protected from harmful substances
B. Enzymes would not be able to speed up reactions in the nucleus.
C. The nucleus would not be able to communicate with the rest of the cell.
D. Large molecules would be able to enter and damage the nucleus.
Answer:
D
Explanation:
If the layer of nucleus were permeable to most substance, then the large molecules would be able to enter and damage the nucleus.
What is nucleus?It is a membrane-bound organelle present in the centre of cell in which thread like structures called chromatins are present which condenses to form chromosomes contains genetic material (that carries genetic information from parents to offspring).It controls all function of the cell.The layer or membrane around nucleus is called nuclear membrane is semi-permeable in nature which means that only specific molecules and ions can move across it.If the membrane would become permeable, then movement of all types of molecules will occur which will disturb the homeostasis (maintaining balance) of cell and can damage the nucleus.Hence, the correct option is: D. Large molecules would be able to enter and damage the nucleus.
