Hemophilia is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree.
Charles
Marie
Luke
Who has hemophilia in the pedigree that is shown?
John
Fred
Jack
Ann
Irene
Fred and Luke has hemophilia as shown in the pedigree.
On the pedigree, it is clear that they suffer from hemophilia because they appear colored, because males(XY) need only one allele for hemophilia to be sufferers.
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern ,a sex-linked recessive disease. In males (having only one X chromosome), one mutated copy of the gene in each cell is sufficient to cause Hemophilia that is if they inherit an affected X chromosome that has mutation in the factor VIII or factor IX gene(clotting factor gene)
And because the defective genes are present on the X chromosome only and not on Y chromosome and as father always contributes only a Y chromosome and never passes on X chromosome to his son,so the gene for haemophilia can never be passed from a father to his son.

ivan is investigating the path of home runs in baseball
The correct answer is the last option which states the distance that each home run travels.
This is because, the main aim of Ivan is to investigate the path of home runs in baseball. And, the best way to do so would be to calculate the distance that each home run travels. By studying the time of the day when each home run is hit, he won't be able to examine the path. It would rather be more useful to see at what time the frequency of home runs is the maximum. The scores of the game would also not reveal the path travelled by the home runs as they are not calculated on the basis of the distance travelled. Similarly, the names of the players hitting the home runs might not provide the necessary information for this experiment.Thus, the correct answer is the distance that each home run travels.

Killer whales need approximately 55 kcal daily to survive. If the phytoplankton population
produced 600,000 kcal, what is the maximum number of links there could be in the food
chain to ensure the killer whale got enough energy to survive?
Microorganisms that resemble plants called phytoplankton are found in lakes, rivers, and the oceans. Most whale species take in between 2,000 and 10,000 pounds of plankton each day on average.
How many calories do killer whales need?Williams extrapolated from this research to calculate the killer whales' estimated daily calorie intake. She determined that a 4.5-ton male would require 290,000 kilocalories per day and that an adult female weighing around two tons would require more than 190,000.
Microorganisms that resemble plants called phytoplankton are found in lakes, rivers, and the oceans. More phytoplankton than stars can be found in the world's oceans, which contain a billion billion billion phytoplankton. There are perhaps 100,000 different types of phytoplankton, which is quite diverse.
Most whale species take in between 2,000 and 10,000 pounds of plankton each day on average. They only consume, though, during the feeding season.
10,000 pounds of phytoplankton support every pound of whale weight. The energy transfer is inefficient, which reduces the number of killer whales that can survive and procreate. Additionally, it implies that killer whales must put in a lot of effort to get the food they require.

Carrying capacity is the average size of a population that can be sustained over a long period of time in a particular habitat. The population size is limited by environmental factors such as food, water, diseases, mates, and shelter. If a population is larger than the carrying capacity, the environment becomes degraded, reducing resources and causing the population to crash.
Using the information above, discuss whether the human population has reached, exceeded, or not yet reached its carrying capacity on Earth. Why do you think it has or has not? In your response, be sure to think about the current state of the environment.
The carrying capacity of the earth has not been reach because the modern technology has kept increasing the earth's carrying capacity.
What is earth carrying capacity?The earth's carrying capacity is the average amount of life the earth can support which ranges from 9 billion to 10 billion people. However, this figure keeps changing.
The change in the carrying capacity of the earth is being affected by the following:
Food availability, Safe water,Advancements in technology,Disease Control andSpace.Currently, the capacity of the earth is affected by the advancement in technology which has led to increase in depletion of the ozon layer.

In multicellular and unicellular creatures, cells behave differently. A multicellular organism has cells that are specialized to perform several functions that collectively maintain the organism, as opposed to a unicellular organism that relies on only one cell to conduct all of its functions.
The identical set of genes are present in every cell in an individual. But which proteins are produced by each sort of cell depends on which pattern of genes are turned on. The distinct protein composition of each type of cell enables it to carry out certain functions. They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks. Additionally, cells have the ability to replicate themselves and contain the body's genetic material. Each component of a cell has a different purpose.

Feldspar has a hardness of 6 and they improve the toughness durability and strength of the ceramic body.
The feldspar is considered the group of rocks which forms the aluminum tectosilicate minerals and they also contain other types of cations such as sodium, barium, potassium, and calcium.
The minerals that scratch the glass they have to be harder than 5.5 inches and feldspar can be used on a glass plate to do this feldspar is needed to run over anything which is harder than 6 inches otherwise detecting hardness is hard.
A copper penny has a hardness of about three hence the hardness test by a copper penny is not possible by a feldspar.
A streak plate has a hardness of over 6.5 to 7 and that is why it can be used to detect the hardness as feldspar has a hardness of 6 it can be run over the streak plate and a test can be done.
The benefits of feldspar are it has good dispersibility, has high chemical inertness so is not much reactive, ph is stable, resistant to abrasion highly, it has low viscosity at high filler loading and it cannot get frozen and also has a good refractive index.
it is fine-milled graded and used in many different products.
