what is the broad, fan-saped peritoneum fold that suspends and encircles the jejunum and ileum to the dorsal wall of the abdomen?

Answers

The broad, fan-shaped peritoneum fold that suspends and encircles the jejunum and ileum to the dorsal wall of the abdomen is known as the mesentery.

The mesentery is a double layer of peritoneum that attaches the small intestine to the posterior abdominal wall, providing support and maintaining its position. It contains blood vessels, lymphatics, and nerves that supply the small intestine. The mesentery also plays a vital role in the immune system by housing lymph nodes and immune cells that help fight against infection and inflammation. Recent studies have shown that the mesentery is an independent organ, and not just a supportive structure for the small intestine. The discovery of the mesentery as an independent organ has opened up new avenues for research in fields such as gastrointestinal disease, surgery, and immunology. Understanding the mesentery's structure and function is critical for diagnosing and treating disorders of the small intestine and maintaining overall health.

b. Natural selection caused pigweed to mutate, creating a new triazine-resistant species
c. Triazine-resistant pigweed is more efficient at photosynthesis.
d. More triazine-resistant individuals survived each year, soi more individuals were triazine-resistant.
e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring

Answers

Answer:

e. Some individuals acquired triazine resistance during their lifetimes, and were able to pass it on to offspring

Explanation:

The term resistance in the exposed example refers to an inheritable change in the weed population sensitivity, which is reflected in the consecutive failure of the chemical effects on the herb population.  

Herbicide might produce a genetic modification in the weed, leading individuals to survive under the effects of the chemical. The plants evolve with the capability of tolerating the chemical dose that is usually used to destroy a normal population of plagues.  

Resistance to the toxic is associated with mutations in some of the genes.

A mutation is a change in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.  

The selective pressure or modeling environmental factor is the triazine herbicide The weed´s response to herbicide is the survival of only those that carry mutations.  Natural selection benefits these mutations.  The mutated herbs survive, become more resistant, and pass the mutation to their offspring.

How is the digestive system related with our diet?

Answers

The digestive system is related to our diet in the sense that this is a specialized organ whose cells known as cylindrical cells, secrete a juice (gastric juice; which is possible because of the gene expression that allows these cells to develop the necessary proteins) that catabolizes the food to acquire nutrients such as glucose from carbohydrates and eventually performs cellular respiration.

The sequences of amino acids that make up a protein molecule are specified by:
a. age.
b. sex.
c. heredity.
d. the diet.

Answers

The sequences of amino acids that make up a protein molecule are specified by heredity.

The sequences of amino acids in a protein molecule are determined by the genetic information encoded in an organism's DNA. DNA contains the instructions for building proteins through the genetic code, which is a set of rules that specify how the sequence of nucleotides in DNA corresponds to the sequence of amino acids in a protein. This process is known as protein synthesis or translation.

During protein synthesis, the DNA sequence is first transcribed into a messenger RNA (mRNA) molecule. The mRNA molecule carries the genetic information from the nucleus to the ribosomes in the cytoplasm. At the ribosomes, the mRNA sequence is read in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid or a stop signal.

The transfer RNA (tRNA) molecules, which are small RNA molecules, have specific anticodons that match with the codons on the mRNA. Each tRNA molecule carries a specific amino acid that corresponds to its anticodon. As the ribosome moves along the mRNA, the tRNA molecules bring in the corresponding amino acids, which are then linked together in a specific order dictated by the mRNA sequence. This process continues until the entire protein molecule is synthesized, with the amino acids arranged in the sequence specified by the DNA.

c. High doses of vitamin A are especially useful in acne associated with pregnancy.
d. Accutane (isotretinoin), made from vitamin A, is effective against cystic acne.

Answers

D. Accutane (isotretinoin), made from vitamin A, is effective against cystic acne.

Accutane (isotretinoin), which is made from vitamin A, is effective against cystic acne. This statement accurately describes the relationship between vitamin A and acne. Option A.

What is vitamin A: Vitamin A is a fat-soluble vitamin that is naturally present in certain foods and is available as a dietary supplement. Retinol, retinal, and retinoic acid are all forms of vitamin A that come from animal foods.Vitamin A helps to keep the skin healthy and moisturized. It aids in the formation of new skin cells and tissue regeneration, making it critical for wound healing.

Vitamin A is an essential component of some topical acne treatments as well, such as tretinoin. Vitamin A also aids in the regulation of the skin's oil production. It aids in the avoidance of clogged pores and acne as a result of it.However, excessive consumption of vitamin A can cause side effects such as headaches, dizziness, nausea, and more serious issues.

Isotretinoin, commonly known as Accutane, is a medication used to treat severe acne that is derived from vitamin A. Isotretinoin functions by preventing the production of oil by the sebaceous glands in the skin. As a result, isotretinoin is only prescribed to people with severe cystic acne who have not responded to other treatments.

2 Which substance, needed for protein synthesis, is carried into a leaf from the stem? A carbon dioxide B nitrate C oxygen D starch​

Answers

The substance, needed for protein synthesis, that is carried into a leaf from the stem is nitrate. Nitrate is an essential nutrient that plants use to produce amino acids and proteins. It is a part of the nitrogen cycle and is used in chloroplasts to create essential proteins.Option B is correct

The process of protein synthesis takes place in chloroplasts of the leaves of plants where nitrogen, along with other elements, is utilized to produce proteins. Nitrogen, in the form of nitrate, is an essential element required by the plant for the synthesis of amino acids and proteins.

Plants obtain nitrate through the soil from the water they absorb through their roots. It is transported from the roots to the leaves through the xylem vessels, which form a continuous pipeline from the roots to the stem and leaves of the plant. The process of protein synthesis is important for the growth and development of plants.

It is essential for the production of enzymes, hormones, and structural components such as cell walls and membranes. Nitrate is, therefore, a critical substance for protein synthesis and the growth and development of plants. Option B is correct

where in the fossil record would you expect to see older common ancestors

Answers

the level at the bottom can see the fossil record of older common ancestors. Both the unity and the diversity of species are explained by biological evolution, the process by which all living organisms have evolved over many generations from common ancestors.

The similarities across species, which can be explained by the inheritance of similar traits from related ancestors, serve as illustrations of the unity. The diversity of species is also consistent with a common ancestor; it can be explained by the branching and diversification of lineages as populations changed in response to their environments, chiefly through natural selection.

The fossil record, comparative anatomy and embryology, the similarity of cellular functions and structures, and DNA sequence comparisons between species are all sources of evidence supporting shared origin.

Researchers are analyzing the genetic basis for some of the changes seen in the fossil record and those that can be inferred to link living species (like the armadillo) to their ancestors. As a result, our understanding of evolutionary relationships has recently been greatly accelerated (e.g., glyptodonts, a kind of extinct gigantic armadillo).

This is the concept in a nutshell:

Precipitation is rain/snow/sleet, but mostly classified as rain. It means when the water in the clouds rains down and hits the ground. Evaporation is the process of the water that hits the ground invisibly going back up into the sky and drying from the ground. From this point, the evaporated water condenses into clouds, hence the name condensation. From this point forward, the water precipitates again, evaporates again, condense again, and repeat
