Why can two people draw different phylogenic trees using the same data and still both be correct?

Answers

The most common misinterpretation that does not change the result is related to taxa relatedness is to use the distance between taxa in phylogenetic trees to determine relatedness, i.e., the proximity of branch tips, often referred to as “tip reading”. Branches can be rotated around nodes, however, so that the positions of taxa are arbitrary.

What is phylogenetic tree?

A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.

What is the advantage of a phylogenetic tree?

It helps us to understand how species are related to each other. The evolution of animal species has been prolific (the estimates go into the millions and tens of millions).

Why is retinoblastoma more common in individuals who have inherited the RB deletion and have the genetic predisposition for retinoblastoma?

Answers

Answer:

Retinoblastoma is more common in people due to the mutation of RB gene in them.

Explanation:

Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.

When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.

Answers

All animals are multicellular.

All animal have cells that contain a nucleus and organelles. These two are the correct statements.

Animals have a huge variety of characteristics that set them apart from species in other kingdoms, despite the fact that they all belong to the animal kingdom. The vast majority of animals have specialized tissues, and all animals are eukaryotic, multicellular organisms. The majority of animals are mobile, at least at some points in their lives. Animals need nourishment in order to thrive and grow. Every animal is heterotrophic, meaning they consume both live and dead organic stuff. They differ from autotrophic creatures like most plants, which produce their own nutrition through photosynthesis, and from fungi, which externally digest their food, in that they receive energy in this manner. Animals can be parasitic, herbivorous, carnivorous, or omnivorous.Most animals reproduce sexually, and unlike plants, the young go through a sequence of developmental stages that shape their body plans.

Therefore, all animals are multicellular and have cell organelles.

explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis

Answers

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

What do buffers do and why are they important in biological systems

Answers

Organic acids that are end products of metabolic reactions, protein catabolism, and other biologically active molecules are continually being produced in living organisms. Maintaining the pH in intra- and extracellular fluids is essential since it influences the biological activity of proteins, enzymes, hormones, the distribution of ions through membranes, etc... The way in which we can regulate the pH within of the limits compatible with life are: 1) physiological buffers and 2) the elimination of acids and bases by respiratory and renal compensation.

Explanation:

A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.

The number of protons is equal to its atomic number. Neutral atom means that the charge in the atom is 0. In order to make the charge 0, the proton and electron charges have to be additive inverses, meaning the sum of the proton and electron charges have to be 0. Each proton has a +1 charge while each electron has a -1 charge. Hence, the number of protons and electrons have to be equal.

How would you know when homeostasis has been reached in your egg and syrup system?

Answers

The egg and syrup system

because the egg membrane is semi-permeable, water can flow in however proteins can not flow out. If a egg is positioned in the corn syrup the egg will shrink. this is also because of osmosis, but inside the opposite direction. The corn syrup is more often than not sugar.

What takes place whilst you go away an egg in water for twenty-four hours?

depart the egg within the water for 24 hours. The water will migrate from the side of the membrane wherein water molecules are abundant (outside the egg) o the side where water molecules are less considerable. After 24 hours, the egg will be plump once more.

What takes place whilst you positioned an egg in vinegar then corn syrup?

as the vinegar reacts with the eggshell, bubbles surround the egg, inflicting it to waft. while the egg is placed in the salt water, it sinks to the lowest of the beaker again, considering the fact that it's miles greater dense than the salt water solution. The egg floats inside the corn syrup due to the fact the corn syrup is extra dense than the egg.

Additionally, there should be a 1:1 stoichiometric ratio between the purine and pyrimidine bases (A+G=T+C).

As per the Question,

If, A=10 then T=10 because A always pair with T. If T=10, then G=40, and then C=40. The total sum is equal to 100 or A + G (10 + 40) = T + C (10 + 40). Which ratio is equal to 1:1.

Bacteria are the microorganisms that are the most primitive on earth. These are omnipresent. Bacteria can be both harmful as well as useful. The bad bacteria cause several diseases whereas the good bacteria help in digestion, nitrogen fixation, curdling of milk, etc.

Phagocytosis is a type of endocytosis. It is also called cell-eating. In phagocytosis, cell engulfs solid large bacteria completely. This is done by forming extensions of the plasma membrane called pseudopodia. These pseudopodia then fuse and pinch off to form endocytic vesicles.
