Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.
Answer: the answer is A
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.
What can you infer is the reason fruit flies are the most commonly used organism for this type of investigation
In the case of genetic investigation, scientists used fruit flies as their model organism since they share 75% of the genes that cause disease with humans. Fruit flies are also great to work in a research setting because they are relatively easy to take care of, especially compared to larger and more expensive organisms like rats or fish.Answer:

What is unique about active sites?
A: active sites provide cells with energy.
B: active sites are specific to certain substrates (reactants).
C: active sites store the genetic information of cells.
The Unique feature of Active sites is that active sites are specific to certain substrates (reactants)
Active sites are specific regions of an enzyme where substrate molecules bind in other to bring about a chemical reaction.
The active site is made up of amino acid which forms temporary bonds with the substrate otherwise known as the binding site and the residues which brings about a reaction of that substrate.
Active sites are specific to certain substrates (reactants). Therefore, option (B) is correct.
Active sites are vital to enzymes, proteins that aid biological processes. They have a distinctive form that matches their substrate molecules. This specificity allows only particular substrates to bind to and interact with the active site, catalysing processes. This is called the "lock and key" or "induced fit" model.
Enzymes' catalytic action depends on active sites. A substrate attaches to an enzyme's active site and changes conformation, lowering the reaction's activation energy. This speeds up the reaction. After the reaction, the products are released and the enzyme's active site can bind to another substrate. Therefore, option (B) is correct.

the protein that carries oxygen in our blood is known as
Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.
What is Hemoglobin?The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.
When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

what processes in your cells produce the co2 that you exhale?
Answer:
Co2 is released from the pyruvate that is formed during glycolysis, and CO2 is also released during the citric acid cycle.
Explanation:
Cellular respiration in mitochondria produces [tex]CO_2[/tex] as a waste product, exhaled during breathing.
Cellular respiration occurs mostly in mitochondria. During cellular respiration, glucose and other nutrients are broken down to make ATP. This procedure produces [tex]CO_2[/tex]. [tex]CO_2[/tex] from mitochondria diffuses into the circulation.
Breathing exchanges [tex]CO_2[/tex] for oxygen in the lungs from the circulation. Your body releases [tex]CO_2[/tex] when you exhale. This important cycle eliminates unwanted [tex]CO_2[/tex] and supplies cells with oxygen for respiration and energy generation.

What is DNA replication?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological heredity.
There are two stages to the beginning of the DNA replication process. To begin, a protein known as an initiator unwinds a portion of the DNA double helix along a very short region. After then, a protein that is known as helicase attaches itself to the DNA strands and breaks the hydrogen bonds that are present between the bases. This results in the two strands of DNA being separated.
When two single strands of DNA are cut apart, a 'Y'-shaped structure is produced that is referred to as a replication 'fork.'

Explanation:
In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.
