I was asked this question a few weeks ago so here you ago!

Hyaline Cartilage is (a) can be found between vertebrae, serving as shock-absorbing.

Cartilage is an elastic connective tissue that exists in various parts of the body. The smooth surface of hyaline cartilage appears to be glassy. The cells that make up this type of cartilage are chondrocytes, which are surrounded by an extracellular matrix consisting of collagen and elastic fibers, as well as proteoglycan molecules.

Hyaline cartilage is the most prevalent form of cartilage. It's found in the end of bones, the larynx, the trachea, the bronchi, and the embryonic skeleton. It's found in the articulating surfaces of bones as well as between vertebrae, where it serves as a shock absorber.

The articular cartilage also aids in the lubrication of the articulating surfaces. There is no blood supply to cartilage, so it must receive nourishment via diffusion from surrounding connective tissues. The other options in the given question are incorrect because: The double-layered connective tissue sheath covering it called the periosteum is incorrect because periosteum is the covering of the bone and not the hyaline cartilage.

Hyaline cartilage cannot serve as a precursor for the formation of long bones in the body as the precursor of long bones is the hyaline cartilage model. Lastly, hyaline cartilage cannot grow on the outside by appositional growth and on the inside by interstitial growth, because hyaline cartilage only grows by interstitial growth. The correct answer is A.

Answer:

Adapted to the environment

Explanation:

The thickness, shape, and size of leaves are adapted to the environment. Each variation helps a plant species maximize its chances of survival in a particular habitat.

Answer:

D. how they have adapted

Explanation:

Answer:

Exons.

Explanation:

In mRNA maturation and processing, a complex called a splicesome essentially "cuts out", if you will, non-coding parts of the DNA sequence to be translated. The parts that are cut out are called "introns", and the parts that are left over that code for a protein sequence, are called "exons". Careful with the terminology. It seems counterintuitive that exons are the ones that stay (exon = exit? NO.) and introns (in, as in, stays in? NO.) are the ones that are cut out of the mature mRNA. Perhaps you can remember that the terms seem to be the opposite, that's how I remember it. Alright, good luck with all of this.

Answer:

A. They are lipid-soluble.

Explanation:

Hope this helps!

The property that defines most ligands for intracellular receptors is that they are lipid-soluble. (option.a)

This means that they are able to dissolve in lipid-based substances, such as cell membranes. Intracellular receptors are located inside cells, so the ligands must be able to pass through the cell membrane to reach the receptor.

Lipid-soluble ligands are able to do this, whereas hydrophilic molecules are not. Additionally, lipid-soluble ligands are typically non-polar, allowing them to interact with the non-polar environment of the receptor.

While some ligands may also perform significant hydrogen bonding interactions with water or be large molecules, these characteristics are not necessarily defining for most intracellular receptor ligands.

Answer:

See the answer below

Explanation:

Zara should keep Bozo in a separate salt water-containing tank away from the goldfish.

Bozo is adapted to living in salt waters. If it is kept in saltless water like the goldfish, its cells would lyse and the fish may die. The saltless water would be hypotonic to the cells of Bozo and water moves osmotically from a region of high water potential to a region of low water potential. Hence, the cells of Bozo would take-in water, become turgid, and may eventually lyse, leading to the death of the fish.

The goldfish cannot survive in salt water with Bozo because the water would be hypertonic to its cells. Hence, it will lose water to the surrounding salt water due to osmosis and may eventually die of dehydration.

Sulfur is part of the keratin found in your hair and skin. it also helps with the formation of collagen.

Keratin and collagen belong to the class of fibrous proteins and are essential proteins for the development and growth of strong healthy hair.

Keratin exists in the body as alpha and beta cells and is composed of keratinocyte cells.

Collagen is present in connective tissues and is an extremely vital component that maintains the structure of tresses.

It also contributes to the production of keratin to maintain and promote the health of hair follicles.

The population of birds with large beaks will increase on the island (1st listed) ; The trait for large beaks will be passed on to future generations through natural selection. (3rd listed)

B) 80 /200

Explanation:

Giraffes evolved over many generations to have long necks. Giraffes that had longer necks were more likely to survive than giraffes with shorter necks because they had better access to food. This is an example of natural selection / survival of the fittest.

(the "fittest" [most beneficial/practical] trait is surviving and getting "selected" by nature)

Giraffes are also vertebrates, like humans. In fact, despite their different neck sizes, humans and giraffes have exactly seven vertebrae bones in their neck. This similarity suggests human and giraffe necks are homologous [structures]

...' What are two ways the decrease in seed availability will affect the population of birds on the island?'

The population of birds with large beaks will increase on the island.

  [This is the concept of natural selection / survival of the fittest, they have the most abundant resource [because they are able to eat what is abundant on the island, compared to smaller birds that have a larger decrease in food availability]   ]

The trait for large beaks will be passed on to future generations through natural selection.

[If these birds / and this trait survive, they will be able to have offspring [future generations]. Birds with a low survival percentage will be less successful in mating, and will likely not produce the same quantity of offspring that will carry on their traits to future generations.]

frequency of an allele:

population: 100

frequency recessive [homozygous bc 2 same recessive alleles]: 25 (tt)

frequency dominant homozygous: 45 (TT)

frequency heterozygous dominant: 30 (Tt)

total alleles: 100 [our population] times 2

100 · 2 = 200

total alleles: 200

number of times we have [dominant] T:

30 from each heterozygous dominant (Tt)

2 · 45 (TT has two T's) = 90 from homozygous dominant

30 + 90 = 120

number of times we have [recessive] t :

30 from each heterozygous dominant (Tt)

2 · 25 (tt has two t's) = 50 from each homozygous recessive

30 + 50 = 80

So, we know that the frequency of recessive allele [t] is 80 / 200

[80 out of 200]

So, option B) 80 / 200 is correct

(this = 0.4)

(and dominant [T] is 120 / 200; I say this to show that recessive frequency and dominant frequency are calculated the same way!!)

(this = 0.6)

Answer:

indeterminate

Explanation:

The answer would be an indeterminate number of generations.

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.

The layer of the blood vessel wall composed of circularly arranged layers of smooth muscle cells is the tunica media.

It is the thickest layer of the vessel wall and is located between the tunica intima and the tunica adventitia. Tunica media is composed of an inner circular layer of smooth muscle cells and an outer longitudinal layer of smooth muscle cells. It is responsible for regulating the diameter of the vessel and, therefore, blood flow and pressure. When the smooth muscle cells contract, the diameter of the vessel decreases, and blood flow and pressure increase. On the other hand, when the smooth muscle cells relax, the diameter of the vessel increases, and blood flow and pressure decrease.

Tunica media is more developed in arteries than in veins. In arteries, the smooth muscle cells are more numerous and organized in multiple layers, while in veins, they are fewer and organized in a single layer. This is because arteries need to withstand the higher pressure generated by the heart, while veins need to resist the backflow of blood caused by gravity.

Sanger sequencing is still widely used for the sequencing of unique pieces of DNA, such as chips used in DNA cloning or bred via polymerase chain reaction (PCR), even though genomes are typically sequenced using other methods that are faster and less expensive.

The use of separate fluorescent markers for each nucleotide, the use of capillary electrophoresis instead of polyacrylamide gel electrophoresis, and finally the introduction of capillary array electrophoresis are examples of improvements that have developed over time in the original Sanger sequencing process.

Shotgun sequencing, which was created to allow for faster sequencing, made the Sanger method better. This method is much faster than long-read sequencing because DNA is broken up into short-read fragments and sequenced in parallel with overlaps.

Folding, followed by erosion are two geologic processes most likely created this landscape region, hence option 3 is correct.

When horizontal sedimentary rock is deposited on top of tilted and eroded rock strata, an angular unconformity develops.

Younger sediments are later deposited on top of the erosional surface when the lower older layers are inclined by folding or faulting and eroded.

Therefore, at or near the earth's surface, weathering (the process of breaking down rock) and erosion (the process of transferring rock material) reduce rocks to ever-tinier fragments.
