3. How many chromatids do you have?
RUBE
Answer:
Six pairs of chromatids.
Explanation:
There are six chromatids pair present if there are 3 homologous pairs of chromosomes because in each chromosome two chromatids are present. A chromatid refers to two identical halves of a replicated chromosome. Each chromatid has two arm like structure called telomere and these two chromatids are attached to one another from a point called centromere. So we can conclude that three pairs chromosomes have six pairs of chromatids.

DNA Replication
Explanation:
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. Additionally, Walther Flemming's drawing of chromosomes. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.

quizlwt Select all that are true regarding gas exchange in a vascular plant. Guard cells regulate whether stomata are open or closed based on availability of water in the plant. Guard cells regulate whether stomata are open or closed based on availability of water in the plant. When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere. When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere. Stomata are open when a plant is low on water, and closed when a plant has plenty of water. Stomata are open when a plant is low on water, and closed when a plant has plenty of water. Plants close their stomata to reduce water loss. Plants close their stomata to reduce water loss. Guard cells regulate whether stomata are open or closed based on availability of sugars in the plant.

Answer:
Transpiration is loss of water vapor from leaves. Guard cells regulate whether stomata are open or closed based on availability of water in the plant. When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphereExplanation:
The gas exchange of plants is part of the cellular respiration process, where the plants both remove and release gases into the atmosphere. This exchange happens through structures present in the leaves of plants, which are called stomata. Stomata function as doors, if they are closed it is impossible for the plant to promote gas exchange, but if they are open. Transpiration occurs with the release of water vapor through open stomata. It is in this water vapor that the plant releases oxygen into the atmosphere.
The opening and closing of the stoma is a highly regulated process, because opening the stoma makes the plant lose water. In this case, the guard cells are responsible for opening and closing the stoma whenever necessary and the plant has good water levels.

Explain how a carbon atom from a CO2 molecule in the air can end up as a carbon atom in a protein in a plant cell
Answer:
Photosynthesis and metabolism are among the most complex areas in biology so given the nature of this forum I've kept the answers simple and brief.
Carbon is of central importance to all biological systems due to its special bonding properties allowing it to form various bonds with other atoms and produce a wonderfully complex range of molecules used by life.
In photosynthesis inorganic carbon in carbon dioxide gas is fixed to hydrogen to produce sugar, an organic molecule. In this case the carbon gains electrons so it is 'reduced' and this process requires energy in the form of light. Once in sugar form, the process can be reversed and the carbon can be oxidised back into carbon dioxide during cellular respiration, releasing energy.
So in photosynthesis, the carbon from carbon dioxide is reduced to form a sugar molecule. When transitioning to respiration, the carbon in the sugar is oxidised to form carbon dioxide again in the reverse reaction to photosynthesis.
The carbon is transferred between molecules through various intermediate steps during these processes, involving enzymes (biological catalysts) to assist in cleaving specific bonds at each stage. During cellular respiration (an energy release reaction) as the carbon is successively oxidised electrons are liberated that are used as part of the energy release. These electrons are captured or 'carried' by special organic molecules called NAD and FAD (reducing them) which in turn can then be oxidised to produce the universal energy currency of life: ATP molecules. ATP is a small bio molecule containing a high energy phosphorous bond that can be broken to release energy to do cellular work. It is used by all life that we know of and is the ultimate product of cellular respiration.
The carbon atom in a CO₂ molecule in the air can become a part of the
cellulose molecule in a plant by the carbon dioxide molecule reacting with the water during photosynthesis to form Glucose.
This formula can use for the reaction: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
The glucose molecule formed is then translocated to other parts of the
plants which are such as the roots and stems and help in the formation of cellulose.

In dogs, spotty fur is a recessive trait. Show a cross between two dogs that are heterozygous for spotty fur. What is the likelihood of these dogs having puppies with spotty fur?
Answer:
The correct answer is - 25% chances of having puppies with spotty fur.
Explanation:
In this question, it is given that spotty fur is a recessive character which means in the heterozygous condition it is not expressed in the phenotype. Here the cross between two heterozygous dogs for spotty fur will produce the following gametes:
Heterozygous: S and s where S is dominant allele and s is the allele for spotty fur that is recessive
Punnett square:
S s
S SS Ss
s Ss ss
By the Punnett square, we can say that likelihood of spotty fur (ss) in puppies is only 1/4 or 25%.

Which of the following actions increases the volume of your lungs?
d. Gases move from areas of lower pressure.
c. Air pressure increases inside the lungs.
a. The diaphragm flattens and moves downward.
b. The rib cage becomes smaller.
Answer:
B
Explanation:
During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle's Law

Put the following molecules in order of the correct sequence they are made in protein synthesis.
Reorder answers
RNA
Protein
Gene
Answer: 1. messenger RNA (mRNA). 2. rna, gene, protein. brainliest?
Explanation:
The end result of transcription is mRNA, and the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.
Transcription is the process in which a segment of DNA is used as a template to synthesize a complementary mRNA molecule. It occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. During transcription, the DNA molecule unwinds, and an enzyme called RNA polymerase binds to a specific region of the DNA known as the promoter. The RNA polymerase then moves along the DNA strand, synthesizing a complementary mRNA molecule using the base pairing rules (A with U, G with C).
The end result of transcription is the production of mRNA. mRNA is a single-stranded molecule that carries the genetic information from the DNA to the ribosomes in the cytoplasm. It serves as a template for translation, where the information encoded in the mRNA is used to synthesize proteins.
Regarding the sequence of molecules in protein synthesis, the correct order is as follows:
Gene: A gene is a specific sequence of DNA that contains the instructions for making a protein. It serves as the starting point for protein synthesis.Transcription (RNA): Transcription is the process in which an mRNA molecule is synthesized from a DNA template. This step occurs in the nucleus.mRNA: The mRNA molecule carries the genetic information from the gene to the ribosomes. It serves as the template for protein synthesis.Protein: Protein synthesis occurs during translation, where the mRNA is read by ribosomes, and amino acids are assembled in the correct order to form a protein.Therefore, the correct sequence of molecules in protein synthesis is Gene → Transcription (RNA) → mRNA → Protein.

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.
