Which condition is required for viruses to reproduce?
Answer:
A host is required so that the virus is able to reproduce.
Explanation:
Unlike bacteria, viruses cannot survive without a host. They primarily survive while attaching itself onto a host's cell. So therefore, in order for meiosis to occur within a virus, it needs a host first. In addition, viruses don't need another virus because viruses are prokaryotic cells.

Removing groundwater for drinking water will stop the water cycle.
True
False
False, removing groundwater for drinking water will not stop the water cycle.
Groundwater, in essence means water present and existing beneath the rock surface. They are stored in the tiny pores of the rock below the earth surface.
Groundwater are the sources of fresh water resources.Rock are drilled with machine to get access to the groundwater.Groundwater are naturally replenished through precipitation, from rivers, lakes and other water bodies.In conclusion, Groundwater form part of the water cycle because after the use of water, its eventually evaporates to the cloud and discharges back into the ground through the rain, rivers, lakes etc.

Which of the following statements about eukaryotic RNA is true?
O -A small cap of extra nucleotides is added to both ends of the RNA.
O -The modified RNA molecule is transported into the nucleus.
-Exons are spliced together.
-Introns are not transcribed from DNA to RNA.
Answer:
A small cap of extra nucleotides is added to both ends of the RNA
Hope you like it
Thank you ❤️
The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.
RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.In conclusion, the statement 'exons are spliced together' is TRUE.

explain the disadvantage in terms of energy loss when humans eat beef rather than legumes
Answer:
Katha Ko Bajja Muchi Ko Chora
The main disadvantage in terms of energy loss when humans eat beef rather than legumes is the inefficiency of energy transfer.
When humans consume beef, they are consuming meat from animals that have themselves consumed plant-based foods. However, energy is lost at each step of the food chain. Plants capture energy from the sun through photosynthesis and convert it into organic compounds.
When animals consume plants, only a fraction of that energy is transferred to the animal's tissues, as some is used for metabolic processes, movement, and other functions.
Therefore, when humans consume beef, they are indirectly obtaining energy from plants but at a much lower efficiency. If humans were to consume plant-based foods directly, such as legumes, they would bypass the energy loss that occurs in the conversion of plant energy to animal energy. Legumes are protein-rich plant sources that can provide comparable amounts of nutrients and energy without the same level of energy loss.
By opting for legumes instead of beef, humans can have a more efficient and sustainable use of energy resources, reducing the environmental impact associated with livestock production and utilizing plant-based sources more directly.

How is the Nucleus like a brain?
Answer:
The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.
The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.
The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.
On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.

The pizza that you ate for lunch is being digested. Summarize what happens to it in your stomach.
Answer:
This is the one.. that i did when i was schooling.. I still hv it thank fully..
Hope it help..!!
Explanation:
The correct answer about the digestion in the stomach of the pizza one eats is - The pizza is churned, mixing with digestive enzymes and gastric acid.
Digestion of the food takes place in the alimentary canal or digestive system. In this organ system different organs are used to digest different food molecules and absorbs them.
Let assume you ate a pizza slice in which it moves through the alimentary canal. it begins from the mouth and ends at colon through the esophagus, stomach, small intestine, large intestine.
Mouth: here pizza is chewed with our teeth, broken down and mixed with our saliva. Saliva also has an enzyme, called amylase, to help break down carbohydrates. This called bolus that moves to the esophagus to stomach.Stomach: a pouch shape organ where the pizza mixes it with gastric juice and digestive enzymes to digest protein by pepsin. The food or pizza now called the Chyme that moves to small intestine.Small intestine: receiving the pizza in the small intestine, pancreatic juices and bile from the gallbladder mixed with it and digest the pizza.The nutrients from the chyme (the pizza) absorbed in the small intestine.Thus, the correct answer is - The pizza is churned, mixing with digestive enzymes and gastric acid.

The DNA sequence AGGCTTCGCGAAGGTAAC would code for the sequence of 6 amino acids.
True
False
Answer:
True
Explanation:
Amino acids are coded from the DNA sequence in groups of three bases, that is, three bases (three letter codes) also called codon codes for (or specifies) an Amino acid.
in the above DNA sequence each of the prospective 6 Amino acids will each require a triplet of bases. Thus, the simple calculation of 6×3 yields 18. Thus we need at least 18 bases in our DNA sequence, barring stop codon, to code for Amino acids.
Counting, the above DNA sequence contains 18 bases exactly.
