Answer:
The last one
Explanation:
Oxygen is a product of the electron transport chain.
True or False
Answer:
true
hope this helps you ☺️☺️
Electron transport chain can be defined as the series of organic molecules and proteins which are embedded in the inner membrane of mitochondria. These molecules are involved in the shutting of electrons from FADH2 and NADH to the [tex]O_{2}[/tex].
The molecular oxygen is the final electron acceptor in this electron transport chain that leads to the formation of water and ATP as the end products. This chain takes place in the mitochondria in both animal and plant cells.
Hence, the given statement is true.

Polydactyly is expressed when an individual has extra fingers and/or toes. Assume that a man with six fingers on each hand and six toes on each foot marries a woman with a normal number of digits. Having extra digits is caused by a dominant allele. The couple has a son with normal hands and feet, but the couple's second child has extra digits. What is the probability that their next child will have polydactyly
Answer:
The probability of the couple´s next child having polydactyly is 1/2 = 50%

The function of some cyclin-dependent protein kinases (CDKs) has been remarkably conserved in evolution. Indeed, coding sequence for the human protein Cdc2 is able to substitute for the CDC28 gene in S. cerevisae and allow the yeast cell to grow and mate essentially normally. The following sequence near the NH2-end of the molecule is identical in both proteins: Gly-Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala. Does this mean that nucleotide sequences of the two genes coding for this region of the polypeptide are also identical
Answer:
No, because the genetic code is redundant
Explanation:
During the translation, a single amino acid may be coded for by more than one codon. It is for that reason that the genetic code is considered to be redundant. Tryptophan is the unique amino acid specified by a single codon. In this case, it is likely that silent mutations at the nucleotide sequence that encode for the Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala protein motif might have accumulated during the evolution of both CDK genes, modifying thus their nucleotide sequences while preserving the same protein sequence.

The image here shows potential outcomes for chromosomes at a particular stage of meiosis. Which questions appropriately assess what is happening in the image. Select ALL that apply.
A) How does crossing over increase the outcome of meiosis?
B) How does fertilization increase genetic diversity in a diploid organism?
C) How does independent assortment increase genetic diversity during meiosis?
D) How many potential combinations result from chromosomes alignment during metaphase I?
E) How does chromosome methylation result in silencing specific genes during gamete formation?
According to the random arrangement of homologous chromosomes in the equatorial plane, the correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?
How does the random arrangement of tetrads occur?During metaphase 1, chromosomes' homologous pairs migrate to the equatorial plane. Once there, they randomly aline facing their kinetochores to the opposite poles.
The random arrangement of tetrads is different in every cell going through the meiosis process. This is because there is no equal alinement between two cells.
When tetrads arrange in the equatorial plane, there is no predetermined order. Each homologous chromosome of each tetrad faces any of the poles and then migrates to it while separating. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell.
This random order in the equatorial plane is what introduces variation into the gametes.
The correct question is D) How many potential combinations result from chromosomes alignment during metaphase I?

Answer:
1. Short-term energy storage
2. Lipids
3. Speed up chemical reactions, support cell's structure
4. Nucleic acids
Explanation:
The image comprising of a tabular representation portrays the four biological molecules, their building blocks and function. The four biological molecules in nature are carbohydrates, proteins, lipids and nucleic acids.
- Carbohydrates are biological polymers made up of monomers called monosaccharides. They function to store energy in cells for a short period of time. Examples are glucose, starch etc.
- Lipids are formed from monomers called FATTY ACIDS. They function in the long term storage of energy. Examples are phospholipids, fats etc.
- Proteins are formed from monomers called AMINO ACIDS. They provide various functions including speeding up of chemical reactions, provide cellular structure support etc. Examples are haemoglobin, melanin, hormones etc.
- Nucleic acids are polymers of NUCLEOTIDES. They function majorly in the storage of genetic information. Examples are DNA, RNA etc.

The cell membrane is ----------in nature
a. Highly permeable b. normally permeable c. not permeable d. partially permeable
Answer:
d. partially permeable
Explanation:
The cell membrane is the cellular organelle that covers and bounds all cells. It forms a boundary around a cell, protecting all other organelles. The cell membrane, according to the FLUID MOSAIC MODEL, contains phospholipid bilayer, proteins etc.
The phospholipid (lipid) content of the cell membrane confers its ability to be SELECTIVELY OR PARTIALLY PERMEABLE upon it. It is said to be partially permeable because it allows the passage of some molecules/substances and blocks the passage of others.

What is the advantage of porous bones in birds?
A. their holes assist in ridding the bird of wastes
B. their holes help keep the feathers intact
C. they are lighter, which helps with flight
D. they are lighter, which makes the bird need less food
Answer:
C. But see the answer under C. Apparently C is the accepted answer.
Explanation:
A. Not A.I don't think that's a problem for gulls especially on beaches.
B. Not B. Their feather do not look like they need much help in keeping their feathers attached when in flight.
C. This is not really the answer, but it is the best answer of these 4. The actual answer is that the bones are porous for better air intake which provides more oxygen and hence they are better able to fly.
D. Not D. Food has nothing to do with the problem. Birds get an adequate amount of food without their wings being porous. See the answer for C.
Answer:
C. they are lighter, which helps with flight
