Why do sex-linked traits follow different patterns of inheratance than other traits
Answer:
Males and females have different sex chromosomes.
Explanation:
Sex Linked trait is controlled by the chromosomes while other traits are controlled by autosomes. The autosomal cells and traits have a constant characteristics in a human being. The chromosomal cells however vary. The male chromosome XY is different from the female chromosome XX.
This is the reason why sex-linked traits follow different patterns of inheratance than other traits as a result of the Males and females having different sex chromosomes is valid.

how is active transport different from facilitated diffusion
Active transport and facilitated diffusion are two different mechanisms of moving substances across a cell membrane, with key differences in energy requirement, direction of movement, and specificity.
What is an active transport ?
Active transport is the movement of molecules or ions across a membrane against their concentration gradient, which requires energy in the form of ATP (adenosine triphosphate). Active transport can move substances from an area of low concentration to an area of high concentration, and it is often used by cells to maintain concentration gradients and perform functions like nutrient uptake and waste removal.
Facilitated diffusion, on the other hand, is the passive movement of molecules or ions across a membrane with the help of transport proteins. Facilitated diffusion moves molecules or ions from an area of high concentration to an area of low concentration, following the concentration gradient, and does not require energy input from the cell. Facilitated diffusion is often used to transport large or charged molecules that cannot diffuse across the membrane on their own.
Another key difference between active transport and facilitated diffusion is specificity. Active transport requires specific transport proteins, called pumps, that are designed to move specific molecules or ions. In contrast, facilitated diffusion can use a variety of transport proteins that are specific to certain molecules or ions, but can often transport a range of similar molecules.
In summary, the main differences between active transport and facilitated diffusion are that active transport requires energy input and can move substances against their concentration gradient, while facilitated diffusion is passive and moves substances along their concentration gradient. Additionally, active transport requires specific transport proteins and can be highly selective, while facilitated diffusion is less selective and can use a variety of transport proteins.

In general, coefficients of relatedness are the same in both directions: A mother is as related to her daughter as the daughter is to her mother, for example. In the haplodiploids, this is not always the case. Provide an example to illustrate this.
Answer:
In bees, The males (drones) genes are 100% the queen's genes (develops from the unfertilized egg), this is haplodiploid, but the females (workers and queens) have 100% of the father's gene but 50% of the mothers (queen)
Explanation:
In relatedness or diploid, both parents share and pass on a complete set of genes to the offsprings, but for haplodiploidy, all the genes of one parent are passed to the offspring excluding the other parent as in the case of drones to queen bees.

Suppose a researcher introduces a mutation into the glucosidase domain of the mammalian glycogen debranching enzyme. The mutation inhibits the activity of the glucosidase but does not affect the other functions of the enzyme. The researcher then introduces the mutated enzyme into mammalian cells that do not express wild type glycogen debranching enzyme. Predict the effect of the mutation on glycogen metabolism.
Answer:
cells will have glycogen molecules with branches of a single glucose residue
Explanation:
Glycogen debranching enzymes are proteins that catalyze the removal of branching from glycogen, which is a multibranched polysaccharide composed of glucose units and serves as a form of energy storage. These enzymes have two catalytic activities on a single polypeptide chain: glucosyltransferase and glucosidase activities, which are both required for glycogen breakdown. Glycogen degradation requires both glycogen phosphorylase and glycogen debranching enzymes. First, a glycogen phosphorylase acts to digest a glycogen branch down to four glucose residues. Subsequently, the debranching enzyme through its glucosyltransferase activity acts to transfer three glucose residues to a nearby branch of the glycogen chain. Finally, through its glucosidase activity, the debranching enzyme cleaves the remaining α-1,6 linkage in order to release free glucose.

Fossils of a species of bear are found in layer 5. Which layer is most likely to have organisms that lived at the same time as the bear species? O A. Layer 1 B. Layer 2 C. Layer 4 D. Layer 8
The correct answer is C. Layer 4.
Explanation
The image shows 13 layers of rocks on the earth's surface that, according to their age, are located from the oldest below to the most recents up. According to the above, if a fossil of a species of bear is in layer number 5, organisms that lived at the same time could be found in number 4 because it is the closest layer to the layer in which the bear species is mostly found and therefore, the layer that was formed at the same time or right before layer 5. According to the above, the correct answer is C.

How is transcription similar to replication and how is it different?
Answer:
Transcription and replication are important processes that occur in cells but have distinct differences.
Similarities between transcription and replication:
1. Both transcription and replication involve the synthesis of nucleic acids. In replication, DNA is copied to produce an identical DNA molecule, while in transcription, DNA is used as a template to produce RNA.
2. Both processes occur in the nucleus of eukaryotic cells, although replication also occurs in the cytoplasm of prokaryotic cells.
Differences between transcription and replication:
1. Template: In replication, the entire DNA molecule serves as the template for copying. However, in transcription, only a specific DNA segment, called a gene, serves as the template for synthesizing an RNA molecule.
2. Product: Replication results in the production of an identical DNA molecule, while transcription produces an RNA molecule that is complementary to the DNA template.
3. Enzymes involved: Replication requires the involvement of multiple enzymes, including DNA polymerase, helicase, and ligase. Transcription, on the other hand, involves RNA polymerase, which catalyzes the synthesis of RNA from the DNA template.
4. Base pairing: During replication, DNA bases pair with their complementary bases (A with T and C with G) to produce an exact copy. In transcription, RNA bases pair with complementary DNA bases (A with U and C with G), resulting in an RNA molecule complementary to the template DNA strand.
Overall, while transcription and replication involve the synthesis of nucleic acids, they differ in terms of their templates, products, enzymes involved, and base pairing patterns. These processes are essential for cell function and crucial in genetic information transfer and maintenance.

How does energy move through photosynthesis?
Answer:
Energy from the sun is absorbed by the chloroplasts in the leaves of a plant. The light energy is converted into chemical energy as the chloroplasts use the light to power the production of glucose from carbon dioxide and water. The glucose is used by the plant to produce energy and build new cells, and any excess glucose is stored as starch. Oxygen is also released as a by-product of photosynthesis.
Answer:
Explanation:
certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

O cleavage and fracture
Answer:
The answer is
2. magnetism and fluorescence
Explanation:
The other properties mentioned are common properties that are used to identify all minerals. As you can see, hardness, color and fracture are common properties that cut across all minerals. Magnetism and fluorescence however, are not very common and are found in only a few special minerals. That is why they are considered special properties.
Hope this helps!
magnetism and fluorescence are considered two of the special properties that are used to identify certain minerals. Thus option B is correct.
what are the properties to identify an object ?
Minerals are the chemical compound which has a well -defined composition and a specific crystal structure and occurs naturally in the pure form.
If a compound occurs naturally in different crystal form then it is referred as a different mineral. The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.
Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure; it has variable composition which is split into separate species.
minerals include color, streak, luster, specific gravity and cleavage as their physical properties, shows no magnetism. Basically magnetism is the physical property of the minerals, magnetism does not have these elements. thus, have no magnetism called diamagnetic. Examples of diamagnetic are quartz, apatite and calcite.
