Explanation:
Hemophilia is a genetic blood disorder where normal clotting of the blood at the site of a wound or injury does not occur. Tom (III-1) has hemophilia, but neither of his parents have it. However, his mother’s father (I-1) (Tom's maternal grandfather) does have it. In fact, no females have ever displayed the trait in Tom's family, but several males have been affected. The inheritance pattern is shown here in a pedigree. What best describes this inheritance pattern?A)sex-linked on the YB)dominant trait on the XC)sex-linked recessive on the XD)dominant trait on an autosome
Answers
Hemophilia is caused by a recessive allele found in the X chromosome, so if a male has the defective gene, he will present the disease, because it's the only copy of the gene that he has.

Planetary systems form from the combination of many small collections of matter into large, massive spheroids. Which statement correctly describes how the
small particies of matter combine at the beginning of this process?
Answers
Planetary systems form from the combination of many small collections of matter into large, massive spheroids. The statement correctly describes how the small particies of matter combine at the beginning of this process, small particles of matter combine through a phenomenon called accretion.
Accretion occurs when these particles experience gravitational attraction towards each other, causing them to collide and stick together. As more particles collide and merge, they form larger and more massive bodies, such as planetesimals. These planetesimals continue to grow in size as they attract more particles through gravity. Over time, these growing bodies interact with one another, leading to further collisions and mergers, this process continues until the planetesimals form protoplanets, which are larger and more stable than their smaller counterparts.
The protoplanets continue to accumulate matter, eventually evolving into fully-formed planets. In summary, the small particles of matter combine at the beginning of the planetary formation process through accretion, driven by gravitational attraction. This leads to the formation of larger bodies such as planetesimals and protoplanets, which ultimately evolve into the massive spheroids that make up a planetary system.

In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because there is not much sunlight hitting the ground. Orchids are epiphytes, or plants that grow on other plants. They grow on branches of trees high up in the canopy. They get more sunlight and have more access to pollinators up in the high branches. Orchids lay their roots on the bark of a tree and obtain nutrients and water from their surrounding environment.
In a short answer, identify and describe the type of symbiotic relationship between orchids and the forest trees, and explain the effect of this interaction on each species involved.
Answers
Explanation:
The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).
the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...
The type of symbiotic relationship between orchids and forest trees is commensalism.
What is commensalism?Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.
The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.

1. Which of the following best describes why splicing is important for the detection of a nonsense mutation?
A. A mRNA that is not spliced cannot be exported from the nucleus.
B. An mRNA that is not spliced will not have exon junction complex proteins associated with it.
C. An mRNA that is not spliced cannot be bound by the ribosome.
Answers
The best description for why splicing is important for the detection of a nonsense mutation is option B: An mRNA that is not spliced will not have exon junction complex proteins associated with it.
Splicing is a crucial process in which introns are removed from pre-mRNA, and exons are joined together to form mature mRNA. It plays a significant role in generating functional mRNA molecules that can be translated into proteins. In the context of detecting a nonsense mutation, the presence or absence of splicing can have important implications.
Option A suggests that a mRNA that is not spliced cannot be exported from the nucleus. While splicing is necessary for mRNA export, it is not directly related to the detection of a nonsense mutation.
Option C suggests that an mRNA that is not spliced cannot be bound by the ribosome. Although splicing is important for proper translation, it is not directly relevant to the detection of a nonsense mutation.
Option B correctly describes the importance of splicing for detecting a nonsense mutation. Exon junction complex (EJC) proteins are deposited upstream of exon-exon junctions during splicing. They play a crucial role in mRNA surveillance mechanisms, including nonsense-mediated decay (NMD). NMD is a cellular process that degrades mRNA molecules containing premature stop codons to prevent the synthesis of truncated and potentially harmful proteins.

The blood carries oxygen to different tissues. This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.
There are two principal types of circulation
Lung circulation Moves blood between the heart and the lungs. Deoxygenated blood goes from the heart to the lungs In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again. Carbon dioxide is released by exhalation. Blood absorbs oxygen from small air sacs named alveoli. Oxygenated blood returns to the heart.Systemic circulation Moves blood between the heart and the rest of the body.

There are several van der waals forces:
- Dipole-dipole: this attraction is given when the negative and positive poles of two different polar molecules are going to attract each other.
- Ionic interactions: when a polar molecule is going to induce a dipole in another non-polar molecule that will be transient.
- London forces: when in nonpolar molecules there is a displacement of their electrons generating a dipole.

Describe TWO structural suitability of the villi for absorption
Answers
Answer:
Explanation:
Villi are filled with blood capillaries, and the blood constantly moving in them means that a steep concentration gradient is maintained. This increases the amount of dissolved, digested food that can be absorbed into the bloodstream from the small intestine.
Every square inch of the intestinal mucosa is comprised of around 20,000 villi, and the surface cells of the mucosa also have projections of their cell membranes called microvilli, all of which contribute to the increased surface area. This enables a great area to be available for the absorption of nutrients.
Provide a scientific explanation on how a mutation to the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein.
Answers
Answer:
Change in DNA leads to change in the structure of the cell.
Explanation:
Mutation in the 17th nitrogen base of DNA leads to the formation of sickle cell hemoglobin protein instead of normal hemoglobin protein because mutation is the sudden change that occur in the genes of a cell which change the genetic makeup of the cell. So when change occur in the DNA, a sickle cell is formed instead of normal hemoglobin. Normal hemoglobin only formed when the no change occur in the nitrogen base of DNA.
