Look at the albino whale people have named Migaloo. The white color is the result of mutations in the genes that code for the proteins responsible for skin color. Is Migaloo’s white color likely to be an advantage in its current environment? Explain your answer.
No, the white color of Migaloo is not most likely an advantage in its current environment. This is because white is the color that is easily perceived by predators.
What is the Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism. An organism that undergoes an event of mutation is known as a Mutant. The agents of mutation are known as mutagens.
White color is easily perceived by predators as compared to black, brown, grey, etc. So, it somehow reduces the fitness and survivability of Migaloo. This white color is the result of mutations in the genes that code for the proteins responsible for skin color.
Therefore, the white color of Migaloo is not most likely an advantage in its current environment.

1. Which of the following statements about telomeres is
incorrect?
a) They function like a counter, keeping track of how many
times a cell has divided.
b) At birth, they are long enough to permit approximately
50 cell divisions in most celk.
c) They are slightly shorter in prokaryotic cells than in
eukaryotic cells.
d) They function like a protective cap on chromosomes
e) They contain no critical genes.
The statement 'telomeres are slightly shorter in prokaryotic cells than in eukaryotic cells' is INCORRECT (Option C).
Telomeres are DNA sequences localized at the ends of eukaryotic (linear) chromosomes.
These DNA sequences (telomeres) are composed of nucleotide tandem repeats.
Most prokaryotes (e.g., bacteria) have circular genomes and therefore they do not have telomeres.
In conclusion, the statement 'telomeres are slightly shorter in prokaryotic cells than in eukaryotic cells' is INCORRECT (Option C).

a
Answer:
d isotope concentration
Explanation:
A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.
Isotopes can be defined as the atom of an element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic.
We can accurately determine the age of a rock or fossil by measuring its isotope concentration. This can be achieved through the use of radiometric dating.
In Science, this process is known as absolute dating and it can be defined as a process used to accurately determine the age of a rock or fossil by measuring the decay of isotopes associated with the rock or within the fossils.
Hence, these informations when properly obtained is used to determine the age of a rock or fossil because the parent material decays into a stable daughter elements at a constant decay rate.

pls what is a strain in microbiology
[tex] \huge \sf{strain}[/tex]
A strain is a genetic variant or subtype of a microorganism (e.g., a virus, bacterium or fungus). Microbial strains can also be differentiated by their genetic makeup using metagenomic methods to maximize resolution within species.
Type strains are descendants of the original isolates used in species and subspecies descriptions, as defined by the Bacteriological Code [14], that exhibit all of the relevant phenotypic and genotypic properties cited in the original published taxonomic circumscription

The molecular attraction of a substance never changes.
True or False?
Molecular attraction for a substance remains same thus, statement is true.
What is molecule?When one or more atoms are held together to form a group, with help of chemical bonds which are nothing but attractive forces, referred to as molecules.
Molecules as elements of matter and are common. They also make up most of the oceans and atmosphere. Most organic substances are molecules. The substances of life are molecules, e.g. proteins, the amino acids of which they are composed, the nucleic acids (DNA and RNA), carbohydrates, fats, and vitamins. The nutrient minerals are generally ionic compounds, thus they are not molecules.
Different substances have different levels of attraction, but the level of molecular attraction for any one substance is always the same. Therefore, the statement is true.

Why do you get hungry?
Feeling hungry is your body's way of
telling you that your cells need
energy. All cells need energy to live,
grow, and reproduce. Plant cells get
their energy from the sun. Many
animal cells get their energy from
food.
Where do humano
Answer:You may feel hungry frequently if your diet lacks protein, fiber, or fat, all of which promote fullness and reduce appetite. Extreme hunger is also a sign of inadequate sleep and chronic stress. Additionally, certain medications and illnesses are known to cause frequent hunger.
Explanation:
"Hunger hormones" (ghrelin) in your blood and an empty stomach signal the brain when you're hungry. Nerves in the stomach send signals to the brain that you're full, but these signals can take up to 20 minutes to communicate -- and by that time, you may have already eaten too much.

Calculate the colony forming units/ml of original sample if you counted 250 colonies on plate with a dilution factor of 10^5. Give your answer in scientific notation.
Answer:
The correct answer is = 2.5× 10^7.
Explanation:
Colony Forming Units/ml (CFU/ml) in the original sample can be calculated by the countable plate is multiplied by 1/FDF.
Given:
colonies counted on the plate = 250
Forming dilution factor = 10^5
solution:
CFU/ml = 250 x 1/1/100000
= 250 CFU x 100000
= 250,00,000 CFU/ml
= 2.5× 10^7

which organelle does the skeletal system connect to and why?
Answer:
Muscles connect to your skeleton and they contract and move the skeleton along. Your skeletal system is made up of cartilage and calcified bone that work together. They help the process of movement happen in a smoother manner. The calcified bones of your skeleton also work with the circulatory system.
Answer:
Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract. Skeletal muscle cells do contain more mitochondria than other cells, because muscle cells require more energy and must convert more glucose. Skeletal muscle cells also differ from other cells because of the myofilaments within the myofibrils. Within these filaments are proteins known as myosin and actin. The special filaments enable the skeletal muscles to contract. The myofibrils within skeletal muscle cells are divided into units known as sarcomeres, which are the units of skeletal muscle cell contraction.

The term dominant generation refers to
Answer:
The dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant.
The term dominant generation refers with respect to plant classification and characteristics.
What do you mean by Dominant?Dominant is something that masks the effect of others in the same condition.
In Bryophyta (non-vascular plants), the dominant generation is haploid (n), so the gametophyte consists of the main plant. The opposite is observed for Tracheophyta (vascular plants), in which the diploid (2n) generation is dominant and the sporophyte consists of the main plant.
Therefore, the term dominant generation refers with respect to plant classification and characteristics specifically.
