Sooo “Drakes” are dragons and it was in a virtual lab and this is about meiosis. I don’t really know how to answer this because I had trouble with the assignment. Could someone plzzz help me? DONT give links and if u answer with a detailed answer, i’ll give u the crown!!! ✨✨
Answer:
ok, I'm gonna answer this as best as I can. basically, offspring don't look exactly like either parents because half of their genetic makeup comes from the mom, the other from the dad. and the genetics from each parent are always different for each sibling. the certain features each parent gives to their offspring are random. if one parent had a dominant trait for one feature, and the other parent has a recessive, the dominant overrides the recessive and the dominant trait is the phenotype (physical appearance). just because an offspring doesn't have the phenotype of a certain trait doesn't mean they don't have the genotype (the trait's gene) and that they can't. pass it onto their offspring in the future. I hope that makes sense, I tried my best! kinda hard to explain because I'm only 14 and just learned this stuff this year haha.
What will the offspring look like if you crossed a tall pea plant TT with a short one TT )?
If you crossed a tall pea plant TT with a short one TT all the offspring will be tall.
Dominance is the phenomena in genetics where one allele (variant) of a gene on one copy of a chromosome obscures or overrides the impact of another allele (variant) of the same gene on the other copy of the chromosome. [1][2] Dominant refers to the first variant, and recessive to the second.
In both Mendelian inheritance and traditional genetics, dominance is a crucial idea.
No allele or its features are inherently dominant (phenotype). One allele of a given gene may be dominant over a second allele of the same gene, recessive to a third allele, and co-dominant with a fourth allele; the relationship between two alleles of a given gene of any function is strictly relative.

Answer:
1. Homeostasis.
2. Cell membrane.
3. Semi-permeable.
4. Passive transport
5. Osmosis.
6. Facilitated diffusion.
7. Active.
8. Endocytosis.
9. Exocytosis.
10. Protein pumps.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
In order for cells to function properly and stay alive, they must be in a state of equilibrium known as homeostasis.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
One way that cells maintain balance is by transporting material in and out of a cell; the cell membrane is the organelle that is responsible for regulating this process. The cell membrane is called semi-permeable which means that the membrane will allow some materials to enter/exit the cell while preventing others. Thus, it is the wall of the cell and typically controls what leaves and enters the cell.
Some materials can easily move across the cell membrane without requiring energy, this is called passive transport and includes diffusion and osmosis, the diffusion of water. Another type of passive transport requires a protein to move larger molecules such as glucose across the cell membrane. This is called facilitated diffusion.
Other particles require energy to move across the membrane because they move against the concentration gradient and against homeostasis; this type of movement is called active transport. An example of active transport is endocytosis where vesicles are formed to move large particles into the cell and exocytosis where vesicles move large particles out of the cell.
This ultimately implies that, exocytosis is a process in which living organisms release or expel large amount of unwanted material through the use of vesicles. Vesicles are cell organelles that ensure materials are properly transported to the right and exact location.
Additionally, exocytosis is a process initiated by the Golgi apparatus because it prepares the material for export by chemically tagging them.
Protein pumps are another example of active transport that moves ions against the concentration gradient using a protein.

Does cyanide stop ATP production?
cyanide at low concentrations, acts as a mitochondrial activator and stimulatory bioenergetic factor. Its effects are associated with the stimulation of CCOx activity and an elevation of intracellular ATP, leading to a stimulation of cell proliferation.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death. Cytochrome a3 that has been reduced cannot be reoxidized by oxygen. As a result, both cellular respiration and ATP generation are hindered, effectively depriving the cells, tissues, and ultimately the entire body of oxygen.
Electron transport chain is unable to pump electrons into the intermembrane gap after cyanide exposure. The pH gradient would fall, the intermembrane gap pH would rise, and ATP synthesis would cease.

population get to reproduce. Consider the term fitness is used in biology. How does
this term relate to natural selection?
Answer:
Fitness enable organism to survive in the particular environment.
Explanation:
Fitness of organisms is the characteristics which able the organisms to survive in harsh environmental condition and in the process of natural selection. Organisms which are better suited to their environment will survive and reproduce in that particular environment which leads to increase in the population of the organisms. Organisms having more fitness have more chances to survive in that environment whereas those organisms having lower fitness, can't survive and removed from that environment.
In a transformation experiment, a sample of E. coli bacteria was mixed with a plasmid containing the gene for resistance to the antibiotic ampicillin (ampr). Plasmid was not added to the second sample. Samples were plated on nutrient agar plates, some of which were supplemented with the antibiotic ampicillin. The results of E. coli growth are summarized below. The shaded area represents extensive growth of bacteria; dots represent individual colonies of bacteria. Plates that have only ampicillin resistant bacteria include which of the following?
a. I only
b. III only
c. IV only
d. I and II
Option A, The plasmid containing the amp gene was added to the first sample of E. coli, but not to the second sample. Therefore, only the first sample should contain bacteria that are resistant to ampicillin.
This is represented by the shaded area on the plate I, which indicates extensive growth of bacteria. Plates II, III, and IV do not have any shaded area, meaning that there is no extensive growth, and only dots representing individual colonies of bacteria.
Since the plasmid was not added to the second sample it does not have resistance to the antibiotic. This means that plates III and IV, which contain the antibiotic, will not have any ampicillin-resistant bacteria and thus the answer is a. I only.
