What is green algae?
A kind of algae known as green algae are distinguished by their greenish color. The presence of a lot of chlorophylls a and b in the plastids of green algae is what gives them their greenish hue and allows them to photosynthesize. The ratios of these pigments are identical to those seen in vascular plants.

1. how fast was the population of america growing and what were the sources of its population growth?
The population of America is growing very fast. Increasing immigration and high fertility were both contributing to America's population growth. The birth rate, death rate, and migration are the three variables that affect population change.
Cities arose as a result of the enormous workforces needed by industrial companies and the necessity for housing for both the employees' families and themselves. Millions of immigrants came to the United States in search of employment and a better life in factories and cities.
Death rates have dropped as a result of technology, medicine, and diet. Rapid population growth is the term used to describe the aggressive population growth brought on by higher birth rates and lower mortality rates. The availability of food, water, energy, and trustworthy medical care, as well as industrialisation, are other causes.

why didn't any of queen victoria of england's daughters have hemophilia? it is inherited as a sex-linked disorder.
Because King Edward VII, the son of Queen Victoria, inherited her healthy X chromosome and lacked hemophilia. He therefore didn't have a mutated gene to pass on to his offspring.
What is Hemophilia?
An genetic bleeding ailment called hemophilia causes the blood to clot improperly. This may result in both spontaneous bleeding and bleeding after injury or surgery. Blood contains a variety of clotting proteins that can aid in halting bleeding.
What is the cause of Hemophilia?
One affected X chromosome in a female makes her a carrier of hemophilia. A female hemophilia carrier may occasionally exhibit hemophilia symptoms. Additionally, she can pass on to her offspring the X chromosome with the mutated clotting factor gene.

The pattern of genetics in snapdragon flower color is that of incomplete dominance.
When a true breeding red flowering plant (RR) crosses with a true breeding white flowering plant (RR), the resultant plant is heterozygous (Rr) and has pink flowers. One allele does not override the effects of the other, and neither characteristic predominates over the other. Because of this, the phenotypic outcome is a combination of the two phenotypes, resulting in plants with pink flowers (a third different phenotype). As a result, it is a type of intermediate inheritance.
However, no genuine blending of alleles or genetic material is visible—only blending of phenotypes. As a result, it cannot be argued that inheritance is being blended. This phenomenon is also known as intermediate dominance.

The formula v2 = gstartfraction m subscript central baseline over r endfraction is very useful for astronomers because it does not require them to know t. what does t stand for? orbital period tangential speed satellite radius
Using the concepts of Gravitation, we got that T stands for orbital period.
Orbital period is actually the time a certain astronomical object such as planets takes to complete one orbit (360° revolution) around the another object such as sun or stars. Orbital period is expressed in many units of time, usually in years, days or hours.
The gravitational force is that which attracts any two objects with mass. We basically call this force attractive because it always tries to pull masses together, but it never pushes them apart from each other. In fact, every object, including we, is pulling on every other object in this entire universe! This is simply nothing but known as Newton's Universal Law of Gravitation.

There are 3 oxygen atoms on the product side and 3 oxygen atoms on the reactants side.
Explanation:
On the reactant side the Oxygen atom has a subscript (the little number) of 3 but because it has NO coefficient than there is 3 atoms present.
On the product side the first Oxygen atom is by itself no subscript and no coefficient so there is only one but then the second Oxygen atom has a subscript of 2 but no coefficient so there is only 2 so in total there are 3 atoms on the product side.

Because they lack well-defined and complex organ systems, we hypothesize that poriferans diverged from all other animals early in the evolution of animals.
The most primitive animal group, the Porifera, has an early branch on the animal phylogenetic tree, making it likely that it is Precambrian in origin. Sponge is a common name for poriferans. An early branching event in the development of animals separated the sponges and other metazoans from one another. This can be one reason why they lack a well-defined and complex organ system.

Early human creations, such as stone tools and other artefacts, provide evidence of how they lived, interacted mostly with their environment, and changed over time.
Early stone tools, now called as the Oldowan Industrial Complex, were made and used by habilis. These were pebble cores having rough flaking struck off, making "choppers," whose pointed edge was perfect for butchering, chopping, and scraping off flesh from bones.
Many people believe that the earliest Homo species, like Homo habilis, credited with inventing the first basic (Oldowan) stone tools.

The reduction in memory retention over time is predicted by the forgetting curve, also known as Ebbinghaus' retention curve. This curve illustrates how information deteriorates over time when no effort is made to keep it. The strength of memory is a related idea that describes how long memory traces last in the brain. It demonstrates how learnt knowledge gradually fades from our minds unless we take steps to keep it there. For instance, if your company has 10 customers at the beginning of the year and loses two of them, your retention rate is 80%.

The frequency of the heterozygous genotype Aa to the relevant part of the Hardy-Weinberg equilibrium equation is 2pq.
If there is a population of 100 individuals and we have a cross between two heterozygous individuals i.e. Aa × Aa A aA AA Aaa Aa
aawe, we see that the proportion of offspring is: AA = 1/4
which corresponds to 25% of Aa = 2/4
which corresponds to 50% of aa = 1/4
which equals 25% Now,
in solving the Hardy Weinberg equilibrium There are two equations.
p + q = 1p² + 2pq + q² = 1
where: p² exists as the frequency of an individual with a homozygous dominant genotype (AA) = 25%2 pq as the frequency of an individual with a heterozygous genotype

A cell prepares for cell division during the interphase, which is its resting or metabolic phase. The interphase period is when the cell gets ready for mitosis. This is accomplished by multiplying the cell's DNA and enlarging the cell. A typical cell spends the majority of its time during cell division in interphase, which is the phase of the cell cycle.
