Option D: The biomass at the lowest trophic levels of marine systems is typically greater than the biomass at the top, while in terrestrial systems, the biomass at the lowest trophic levels is generally less than the biomass at the top.

The lowest trophic levels in marine ecosystems are occupied by primary producers such phytoplankton, algae, and seagrasses. The marine food web is built on these species, which are also quite productive and produce a lot of biomass. The biomass declines as energy is used and passed up the trophic levels, causing reduced biomass at higher trophic levels.

In contrast, vegetation and plants are primary producers in terrestrial ecosystems. The efficiency of energy transfer declines as it rises up the food chain, despite the fact that they are essential for gathering solar energy and turning it into biomass. As a result, in terrestrial systems, the biomass at the lowest trophic levels is typically lower than the biomass at the top.

The bony projection that is smooth to articulate with another bone is the condyle.

A condyle is a rounded projection at the end of a bone, which is typically smooth and covered in articular cartilage, allowing it to fit smoothly into another bone's articulating surface. This type of joint is known as a condylar joint and is found in areas such as the knee, temporomandibular joint, and the fingers.

Tubercles and tuberosities, on the other hand, are rough projections on a bone where muscles and ligaments can attach. These types of projections are often found on the humerus, femur, and tibia. Trochanters are large and rough projections found on the femur, which serve as points of attachment for the muscles that move the hip joint. In summary, the bony projection that is smooth to articulate with another bone is the condyle, which is important for allowing movement and flexibility in joints throughout the body.

Mast cells have clathrin.

Clathrin is a protein complex involved in endocytosis and cell signaling, it is found in a variety of cell types, including mast cells. Mast cells are a type of white blood cell that is found throughout the body, they play a crucial role in the body's immune response by releasing various chemicals, such as histamine and cytokines, in response to allergens and other stimuli. Mast cells have many different receptors on their surface that allow them to detect a wide range of signals. These signals can trigger the release of various chemicals from the cell, including histamine and other inflammatory mediators.

Clathrin is a protein complex involved in endocytosis and cell signaling. It is found in a variety of cell types, including mast cells. Endocytosis is a process by which cells take up molecules and particles from their environment.Clathrin is composed of three heavy chains and three light chains, which combine to form a cage-like structure that surrounds and internalizes the target molecule or particle. The internalized cargo is then transported to other parts of the cell or to the cell surface for secretion or recycling.

Yes, the class compares favorably to the general population.

The term "general population" refers to the entire human population that possesses a certain trait of interest, such as a specific disease or condition of clinical relevance. It is distinguished from the subject sample that was chosen at random from among that population for a specific research project. The general population that is of relevance in a specific case will be distinct from general populations that are defined in other ways.

If a researcher wanted to evaluate a new behavioral intervention to lower blood pressure, for instance, the general population would consist of all individuals who have high blood pressure. In other situations, it can include all people who have diabetes type 2 (also known as diabetes mellitus type 2). Individuals who have ever smoked, regardless of whether or not they are currently smokers, are considered to fit this definition, even if they do not do so at the present time.

Answer:

Based on the given information , the cellular structure , which don not function properly in Tay Sachs disease  is Lysosomes

Explanation:

LYSOSOMES -: In many animal cells, a lysosome is a membrane-bound organelle. These are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules.  A lysosome, with both its membrane proteins and its lumenal proteins, has a particular composition. There are a number of enzymes in lysosomes, helping the cell to break down different biomolecules that it swallows, including peptides, nucleic acids, carbohydrates , and lipids (lysosomal lipase). For optimal function, the enzymes responsible for this hydrolysis need an acidic environment.

TAY SACHS DISEASE -:  The autosomal recessive disorder Tay-Sachs is caused by mutations in both gene alleles (HEXA) on chromosome 15. HEXA codes for the enzyme β-hexosaminidase A alpha subunit. This enzyme is contained in organelles, lysosomes, which break down large molecules for the cell to recycle.  

Normally, β-hexosaminidase A helps to degrade a lipid called ganglioside GM2, but the enzyme is absent or present only in very small amounts in Tay-Sachs individuals, enabling excessive accumulation of ganglioside GM2 in neurons. In the different types of Tay-Sachs, the progressive neurodegeneration seen depends on the speed and degree of accumulation of GM2 ganglioside, which in turn depends on the amount of functional β-hexosaminidase A present in the body.

Hence , the answer is lysosomes .

Genetic coding for virulence factors can be transferred among various bacteria by plasmids. Plasmids are small, circular, extrachromosomal DNA molecules that exist independently of the bacterial chromosome. They can carry specific genes, including those encoding virulence factors, and can transfer these genes horizontally between bacterial cells.

Plasmids contain the necessary genetic elements for their own replication and transfer. They often possess transfer genes, such as conjugation genes, that facilitate their transfer from one bacterium to another. During conjugation, a plasmid-containing bacterium forms a physical connection, called a conjugation bridge, with a recipient bacterium. The plasmid is then transferred through this bridge, allowing the recipient bacterium to acquire the plasmid and the associated virulence genes.This plasmid-mediated transfer of genetic material provides a mechanism for bacteria to acquire virulence factors and enhance their pathogenicity. It enables the rapid spread of virulence traits among bacterial populations and can contribute to the emergence and dissemination of antibiotic resistance as well. In summary, plasmids serve as vehicles for the horizontal transfer of genetic coding for virulence factors between bacteria, allowing for the rapid acquisition and dissemination of these traits in microbial populations.

The sequence would be ATTCATTCA.

Explanation:

Usually, when a sequence is duplicated, one of them becomes a non-coding. It's just like a computer. There can only be one specific file, or else a duplicated one will just replace the existing one, if you allow the file to do so. Same with DNA. This is why most of our DNA have no function and why we lost genetic abilities such as being able to produce our own Vitamin C.

So instead of the new gene being ATTCATTCAATTCATTCA, it's simply ATTCATTCA. You simply cannot have duplicates, just like computer files.
