Answer:
Maize is monocot and fibrous roots whereas mustard is dicot and tap roots system.
Explanation:
The main difference between maize plant and mustard plants is that Maize is a monocot plant means only one cotyledon in their seed whereas Mustard are dicot which means having two cotyledons. Maize plant has a fibrous root system whereas mustard plant has tap root system. The leaves pf maize plant have parallel venation while on the other hand, the leaves of mustard having reticulate venation. The seeds of maize is bigger in size as compared mustard seed.
Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.
Answer:
Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.
Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.
Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.

Explanation:
Starting with pyruvate to make acetyl-CoA and continuing into the citric acid cycle, and oxidative phosphorylation, how many ATP can be made from 1 molecule of pyruvate
Answer:
The correct answer is - 15 ATPs.
Explanation:
Cellular respiration (aerobic) is the process that involves glycolysis, oxidative decarboxylation, citric acid cycle and oxidative phosphorylation or ETS to breakdown one molecule of glucose in order to generate energy in ATPs. Pyrivate is the end product of glycolysis and it is go to form acetyl CoA.
One molecule of pyruvate genrates 1 molecule of FADH2, four molecules of NADH, and 1 molecule of ATP during oxidative decarboxylation and citric acd cycle. During the oxidation in the electron transport system there is 4 molecules of NADH2, 1 molecule of FADH2, and 12 (4×3) ATP molecules, respectively by oxidation in the electron transport system (ETS).
Thus, there would be 15 molecules of ATPs produce by one molecule of pyruvate.

Answer:
a) mRNA before mutation ⇒ CAG
b) mRNA after mutation ⇒ CAC
c) amino acid before mutation ⇒ Glu, Glutamine
d) amino acid after mutation ⇒ His, Histidine
e) missense mutation
Explanation:
Theoretical frame
Transcription:Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
The template strand is the mRNA complement.
The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
Translation:Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells
• The end codons are UAA, UAG, UGA.
When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.
----------------------------------------------------------------------------------------------------------
In the exposed example,
Before mutation
Original DNI base sequence ⇒ GTC ⇒ Guanine, Timine, CytokineTranscripted mRNA sequence ⇒ CAG ⇒ Cytokine, Adenine, GuanineAmino acid ⇒ Gln ⇒ GlutamineAfter mutation
Mutated DNI base sequence ⇒ GTG ⇒ Guanine, Timine, GuanineTranscripted mRNA sequence ⇒ CAC ⇒ Cytokine, Adenine, CytokineAmino acid ⇒ His ⇒ HistidineThis is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.
Before mutation, the mRNA codon is CAG and codes for Glutamine.After mutation, the mRNA codon is CAC and codes for Histidine.Los Parques Nacionales Naturales de Colombia se caracterizan porque:

Single Strand Binding Proteins are responsible for:
A. keeping the strands separated during replication.
B. unwinding and separating the DNA strands.
C. adding the new bases.
D. linking the short sections of the lagging side.
Reset Selection
Answer:
A. keeping the strands separated during replication
Explanation:
Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.
After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.

The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
The correct answer is - Biwalves and sponges.

Jim has become particularly interested in the genetic basis of cancer and has spent considerable time reading published papers about oncogenes. He learned that as early as 1972 researchers suggested that mutations in proto-oncogenes caused by carcinogens can convert them to oncogenes. He asked you to answer a couple of questions about this because he did not have the biology background to totally understand. Jim learned that some cancer cells produce more growth-stimulating proteins than others. What would you give him as a plausible explanation
Answer:
Proto-oncogenes may have mutated to become oncogenes in these cells
Explanation:
Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.

Why are fungi more like animals than plants?
PLEASE HELP ME
Answer:
Hey mate.....
Explanation:
This is ur answer.....
However, unlike plants, fungi do not contain the green pigment chlorophyll and therefore are incapable of photosynthesis. That is, they cannot generate their own food carbohydrates by using energy from light. This makes them more like animals in terms of their food habits.
