The pedigree shows the original parents numbered 1 and 2. They had three children. Compare the numbers in the ratios you determined to the appearance of the trait in the pedigree. Why were Persons 11 and 12 lactose intolerant while Persons 8, 9, and 10 were not?
Based on the pedigree shown and the pattern of inheritance of lactose intolerance, Persons 11 and 12 were lactose intolerant while Persons 8, 9, and 10 were not because they are hom0zygous for the recessive allele for lactose intolerance while Persons 8, 9, and 10 are heterozygous for the recessive allele for the trait for lactose intolerance.
What is lactose intolerance?Lactose intolerance results from a person's inability to produce the enzyme lactase that breaks down the sugar lactose found in milk. Many adults experience lactose intolerance as they age and rely less on milk and dairy products as sources of nutrition. There is another rare form of lactose intolerance that affects infants from birth. A mutated version of the LCT gene that codes for the production of lactase exist as a recessive allele.
A lack of the body's lactase enzyme is the typical cause of lactose intolerance.
Abdominal cramps, bloating, and diarrhea is examples of symptoms.
Avoiding dairy products, using lactose-free goods, or using lactase tablets are the mainstays of treatment.

In the Galapagos Islands, species of tortoises have been found on
different islands that cannot interbreed. They came from the same
tortoise ancestor, but over time they became separate species
because they were on different islands. Today there are a total of 9
different Galapagos tortoise species. Which type of isolation is
this?
Select one:
temporal isolation
episodic isolation
behavioral isolation
geographic isolation
Answer:
d. geographic isolation
Explanation:
Geographic isolation is the type of isolation that has occurred in the Galapagos Islands with the different tortoise species. This type of isolation occurs when a species is separated by a physical barrier, such as a mountain range, a body of water, or an area of land. In this case, the different islands of the Galapagos served as the physical barrier that separated the tortoises, preventing them from interbreeding and eventually leading to the development of separate species.

Part B: Find Credible Sources
When writing a research paper, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your research paper is credible.
Use sources that end in .gov. These government sites are reliable sources. You can also use sites ending in .edu. They’re generally trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions:
Who authored the document?
Is the author a genetics expert?
What is the document’s purpose?
Does the document state facts that scientists can prove with evidence?
Does the document include opinions?
How old is the document?
Do other credible sources support the document’s statements?
Search for credible websites and note the information they contain. Write down two sources that you’ll use for your research paper, and cite them using Modern Language Association (MLA)
THIS IS ABOUT BULLDOGS
Always using information from credible sources is very important.
The point of view of a source, particularly any potential bias, is a crucial aspect of its credibility. A biased presentation of information is one that is unreliable or unfair. Research or information may be sponsored by an organization with a certain agenda, and this sponsorship may have an impact on the findings. Bias might sometimes occur accidentally.
Also If you are researching a cancer treatment and you use unreliable information without providing reliable identity or data and publish it in your paper, your paper will become very famous for that information because it was new. Therefore, it is imperative that you only use information from reliable sources. However, following studies by scientists revealed that this particular information is false and that the medicine may be lethal.

What are your thoughts on the concept of citizen science, and what projects/activities from SciStarter caught your eye? Would you say you personally connect more with the idea of doing scientific research, doing citizen science, or none of the above? Why?
Answer:
Citizen science is an important concept that allows the public to participate in scientific research and contribute to the advancement of scientific knowledge. It can be a great way to engage people of all ages and backgrounds in the scientific process, and it can also provide valuable data and insights that might not be possible with traditional scientific methods. Some examples of citizen science projects that caught my attention on the SciStarter website include: "Project Nestwatch" which allows individuals to monitor the nesting success of birds and "Project Squirrel" which allows individuals to help track the distribution of different species of squirrels.As a language model, I do not have personal preferences, but I can say that citizen science offers a great opportunity for individuals to participate in scientific research, learn about scientific concepts, and contribute to the scientific community, regardless of their level of education or professional experience.

Natural selection is a mechanism that acts on individuals within a
population. Which is a result of the process of natural selection?
Select one:
O Genetic similarity within the population increases.
O The population as a whole is better adapted to the environment.
O The reproductive rate of the population decreases.
O Adverse changes to the environment become more frequent.
Answer:
The population as a whole is better adapted to the environment.
Explanation:
A population's members can be affected via the mechanism of natural selection. It happens when certain features or population differences provide some people a survival and procreation edge. Since these people are more likely to pass on their favorable qualities to their progeny, the population's proportion of people with these features rises over time. The population as a whole improves its environmental adaptation as a consequence.
It's important to note that genetic similarity within a population grows due to other processes other than natural selection, such as founder effect, inbreeding, or genetic drift. Furthermore, while the population's reproduction rate may decline, this is not necessarily due to natural selection. Likewise, adverse environmental changes that occur more frequently are not always caused by natural selection.

The volume of a sphere is given by the formula 4r3/3. The surface area of a sphere is
given by 4 2. The surface area to volume ratio of a sphere of diameter 2.6 mm is
Answer:
The surface area to volume ratio of a sphere of diameter 2.6 mm can be calculated using the formulas for the volume and surface area of a sphere. The volume of a sphere is given by the formula 4πr3/3, where r is the radius of the sphere. The surface area of a sphere is given by 4πr2. In this case, the radius is 1.3 mm (half of 2.6 mm), and the surface area to volume ratio is 4π(1.3 mm)2/4π(1.3 mm)3 = 3/2π.
Explanation:
The volume of a sphere can be calculated using the formula V = 4/3 * π * r^3, where V is the volume and r is the radius of the sphere.
The surface area of a sphere can be calculated using the formula A = 4πr^2, where A is the surface area and r is the radius of the sphere.
Given that the diameter of the sphere is 2.6 mm, we can calculate the radius by dividing the diameter by 2:
r = 2.6 mm / 2 = 1.3 mm
Now, we can calculate the volume of the sphere using the formula:
V = 4/3 * π * (1.3 mm)^3
We can also calculate the surface area of the sphere using the formula:
A = 4π * (1.3 mm)^2
The surface area to volume ratio (SA:V) of a sphere is the ratio between the surface area and the volume. To calculate the SA:V ratio of the sphere, we divide the surface area by the volume:
SA:V = A/V
It's important to note that the ratio will be dimensionless because surface area and volume both have units of length cubed, thus canceling each other out in the ratio.

Answer:
see below semi-full answer
Explanation:
I am unable to create drawings and take pictures. However, I can help you with the identification of the tissue and the other questions you have.
1. It's probable that the tissue you're viewing is cartilage. Concentric lamellae, which are layers of matrix that enclose the cells, are present in cartilage, a form of connective tissue that has a lot of open space but no discernible fibers. Each lamellae looks to have an empty center region, and the individual nucleus is not discernible.
2. For the most part, cartilage serves to support and cushion the joints and other bodily components. The body's cartilage, a moderately hard yet flexible structure, assists to disperse stresses and absorb shock. Additionally, it offers a smooth surface for joint mobility and aids in keeping the contour of several bodily structures.
3. The ear is one organ where this tissue may be found. The external ear's structure is made of cartilage, which serves to shape and build the ear as well as amplify sound waves. By preserving the ear's structure and enhancing sound waves, cartilage in the ear promotes the ear's ability to operate.
Name Realized Niche SKILL BUILDER Think Visually 3 Redraw the diagram to show the potential effect on the realized niches of Species 1, 2, and 3 if a predator of Species 3 is introduced into the habitat. Species 2 Species 1 Class Species 3 Date - Explain the reasoning you used to create your diagram.
Answer:
Explanation:
If a predator of Species 3 was introduced into the habitat, the potential effect on the realized niches of Species 1, 2, and 3 could be shown as follows:
Species 1 and 2 would likely not be affected by the predator, as they are not a target of the predator. Species 1 would continue to occupy its original realized niche and Species 2 would continue to occupy its realized niche as well, as this niche would be relatively safe from the predator.
Species 3, however, would be greatly affected by the introduction of the predator. Its realized niche would likely shrink or become more specialized to avoid the predator, as it would need to find a way to survive in the presence of the predator. This could be seen in the diagram as the realized niche shrinking or becoming more specific to the area of the habitat that is not occupied by the predator. This would leave Species 3 with less resources, as they would need to avoid the predator in order to survive.

state 2 parts of a cell that makes copies of themselves before mitosis begins
Answer:
All the chromosomes in the nucleus
Explanation:
The centrioles and the chromosomes are two components of a cell that replicate themselves prior to the onset of mitosis.
Cylindrical centrioles are found close to the cell's nucleus. By arranging the microtubules that pull the chromosomes apart during mitosis, they play a critical purpose in cell division. Centrioles multiply to produce two sets before the start of mitosis, which is necessary for the appropriate segregation of chromosomes during cell division.
The lengthy, thread-like structures known as chromosomes transport genetic data. Chromosomes multiply to create sister chromatids, which are kept together by a centromere, before mitosis starts. Each new cell will acquire a full set of chromosomes thanks to this procedure, known as DNA replication.

O the river separated one species of mice into two different species.
O the similar habitat caused two species to become genetically

Answer:
The river separated one species of mice into two different species.
Explanation:
A physical barrier, like a river, divides a population of a species into two different populations, which is a scenario that is most likely an example of allopatric speciation. The two populations may eventually diverge genetically, ecologically, or behaviorally, and they may also stop being able to reproduce with one another and give birth to healthy offspring. The two populations split into two distinct species as a result of their seclusion.
It's important to note that while two species' shared environment led to their genetic similarity, the fundamental cause of their speciation is the physical barrier that divides them.
