Hemophilia is a recessive sex-linked disorder (Xh). A man with hemophilia and a female carrier are concerned about their daughter inheriting the disorder. Use a punnett square explain to these parents the probability (percent chance) that their daughter could have the disorder.
Answer:
The chances of a hemophilic man and a female carrier having a that one of their daughters inherits the disease are 25%.
Explanation:
Since hemophilia is a disease with a sex-linked recessive inheritance pattern —X chromosome— all males who acquire the altered gene will have hemophilia ([tex]X^{h}[/tex]Y), while a female should have both altered chromosomes ([tex]X^{h}[/tex]X) to manifest the disease.
If a hemophilic male and a female carrier of the hemophilia gene have children, the possibility of having a daughter with hemophilia can be seen by crossing.
♂ [tex]X^{h}[/tex]Y♀ [tex]X^{h}[/tex]XAlleles [tex]X^{h}[/tex] Y
[tex]X^{h}[/tex] [tex]X^{h}[/tex][tex]X^{h}[/tex] [tex]X^{h}[/tex]Y
X [tex]X^{h}[/tex]X XY
In the offspring, there are:
Healthy sons 25%.Hemophilic sons 25%.Carrier daughters 25%.Hemophilic daughters 25%.The hemophilic man and the carrier woman should know that they have a 25% chance of having a hemophilic daughter, or that 50% of their daughters may have the disease.

Answer:
c. move by diffusion from outside to inside the cell.
Explanation:
Hi, I'm Isabell G, I'm in actually in your same period lol. I'm not sure if you already did it but yeah here's the answer. I checked it after I submitted it, it's correct.
If a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, the substance will move by diffusion
What are diffusion and its importance?
Diffusion is the transfer of individual molecules of material from a region of higher concentration to a region of lower concentration over a semipermeable barrier
Cells depend on diffusion to get the nutrients they need to develop and obtain energy as well as to rid themselves of waste materials. It helps in gaseous exchange during respiration in organisms.
Thus, when a substance is more highly concentrated outside the cell than inside the cell and the substance can move through the cell membrane, then the substance will move by diffusion

This model shows a human embryo. What can you determine about its development from the model?
It has a postanal tail.
It’s a vertebrate
It has pharyngeal arches.
It has fully developed organ systems.
In humans, tails are vestigial structures, meaning the embryo can express it in early stages of development, but then, they loose it. Option A) It has a postanal tail.
What is a vestigial structure?Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species.
These vestigial structures might be found in many animals, including human beings. They were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.
An example of these structures is the coccyx. This tailbone is the remnant of a missing tail. Actually, all mammals have a tail at some point in their development, even in humans, it is present for a period of 4 weeks during embryogenesis, but after a period of time this tail disappears and its forming vertebras get fussed with each other composing the coccyx.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function. Although it is still an area of muscle insertion.
The correct option is A) It has a postanal tail.

______ and _____ factors cam effect an organisms trait
Explanation: Genes are encoded with different traits. Each of these traits carries different functions to the new offspring that is developing. ... The genes that an organism inherits can affect gene function. For example, they can have a recessive gene for something that might affect them. I hope that this helps you out, have a fantastic day!!
The factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.
What is the significance of the traits and their regulators?Traits are determined by the combination of genetic and environmental factors, such as temperature, light, and nutrition, which affect the expression of genes and the development of an organism's traits, as exposure to certain pollutants leads to mutations in an organism's genetic material.
Hence, the factors that influence the organism trait are the gene and environmental factors, as a result of that, organisms are controlled and regulated in a certain way, and the animals in the rainforest are different from those in the savanna due to this.

Different evolutionary lines that encounter extremely similar forces of natural election tend to become more similar as they evolve. This is known as
Answer:
convergent evolution
Explanation:
Convergent evolution is the evolutionary process by which independent species evolve similar phenotypic traits as a consequence of the adaptation to similar environmental conditions and/or ecological niches. A well-known example of convergent evolution are the wings of birds, insects and bats that evolved separately in these different lineages. Convergent evolution is opposite to divergent evolution in which closely related organisms evolve different phenotypic traits (for example, Darwin's finches, which are closely related species that have both similar and different traits).

The FBI uses STR (short tandem repeat) analysis to identify criminals, and the FBI stores the information in a database. How many regions, or loci, of DNA are used for STR analysis? 5 13 26 30
Answer:
13
Explanation:
Short tandem repeats (STRs), also known as microsatellites, are short DNA sequences containing core repeat units of between 2-7 nucleotides (nts) which are tandemly repeated. The STR analysis is commonly used in molecular biology laboratories in order to identify DNA samples by comparing STR loci between samples. For example, the Federal Bureau of Investigation (FBI) uses 13 STR loci for the identification of individuals in the USA. It is important to note that these 13 loci are independently assorted (i.e. they are not linked), and thereby their combined use results in a very low ("nearly zero") false-positive identification rate.

The Krebs cycle forms many products. Which option lists the correct products of the Krebs cycle after 1 molecule of glucose goes through it.
A. net 2 NADH, 2 ATP, 4 CO2, 2 FADH2
B. net 2 NAD+, 2 ATP, 4 CO2, 2 FADH
C. net 4 NADH, 4 ATP, 8 CO2, 4 FADH2
D. net 1 NADH, 1 ATP, 2 CO2, 1 FADH2
Answer:
Its A
Net 2 NADH, 2 ATP, 4 CO2, 2 FADH2
The Krebs cycle forms 2 NADH, 2 ATP, 4 CO2 and 2 FADH2 after one molecule of glucose goes through it. So the correct option is A.
What is the Krebs cycle?The Krebs cycle is also known as the TCA cycle (tricarboxylic acid) or the citric acid cycle. It is the main source of cellular energy and an important part of the entire process of aerobic respiration.
In this cycle, the available energy of Acetyl coenzyme A is utilized and converted to Nicotinamide Adenine Dinucleotide (NADH). In glycolysis, glucose is utilized to form pyruvate. The pyruvate is oxidized to Acetyl coenzyme A and then it enters the TCA cycle.
The intermediates involved in the pathway also form intermediates for many other pathways to form porphyrins, amino acids, fatty acids etc. Thus, any disturbance in this cycle will not only disturb itself but many other pathways.
Therefore, the end products of the Krebs cycle are 2 NADH, 2 ATP, 4 CO2 and 2 FADH2. Hence the correct option is A.

What happens to the rate of photosynthesis as the intensity of light or concentration of CO2 increases? And How is your conclusion from the question above different from what happens as temperature increases?
Answer:
The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.
Explanation:
Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.
An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
