All chordates share some structures during at least some stage of their development. These are the notochord, nerve cord, pharyngeal slits, and tail.

When talking about chordates we are referring to the chordate phylum. Individuals composing this group share four main structures,

The notochord is a dorsal spine precursor from which the nervous system gets formed.

The notochord is present during the whole individual's life (like some tunicates) or during only the embryonary period (like vertebrates).

The nerve cord is dorsally located, together with the notochord.

It is hollow, and, during embryogenesis, it might differentiate into a brain.

This cord connects external stimuli to the motor system to react to them.

Present only during a period of the embryonary stage. These slits give rise to different organs and structures like tonsils, ears, or gills.

All chordates have a tail in at least a period of the organism's development.

Identify the hormone represented by each letter, in this case, the letter A represents the thyroid glands and letter B represents the parathyroid gland.

The thyroid is a butterfly-shaped gland that is located in the anterior part of the neck, hugging the windpipe. The hormones produced by it  act on our body and metabolism from our fetal formation to senility.

The parathyroids are four glands located in the neck, behind the thyroid, whose function is to control the levels of calcium in the blood through the production of parathyroid hormone (PTH).

These two organs have essential functions for the human body responsible for metabolism.

Answer:

Theories may be revised over time as information is discovered or technology is developed.

Explanation:

A scientific theory is a term used when a statement tries to explain a natural phenomenon of nature based on scientific facts. In short, a theory is the representation of a set of hypotheses that was confirmed through an experiment and that tries to explain a phenomenon, but leaves room for revisions and updates to its explanation.

For this reason, we can say that theories are reformulated, revised and even discredited, when the advancement of scientific knowledge and technology allows the creation of new studies that show a different explanation and more consistent with reality.

Answer:

Carbon flows between each reservoir in an exchange called the carbon cycle, which has slow and fast components. Any change in the cycle that shifts carbon out of one reservoir puts more carbon in the other reservoirs. Changes that put carbon gases into the atmosphere result in warmer temperatures on Earth

Explanation:

hope this answer helps you

It is important for the scientists to refer to inputs and outputs of carbon in the environment as a cycle as carbon continuously flows through these systems in the environment and it is a major biogeochemical cycle.

Carbon cycle is a major biogeochemical cycle. It involves the flow of Carbon between each reservoir present in the environment in an exchange, which has both slow and fast components. Any change in the carbon cycle shifts carbon out of one reservoir and puts more carbon into the other reservoirs. Changes that put carbon gases into the atmosphere results into warmer temperatures on planet Earth.

The fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes. Chitin makes up the rigid cell wall of hyphae. In pursuit of more food sources, they spread out from a tip and continue to expand.

The substrate is broken down by digestive enzymes secreted by the hyphae, which makes it simpler for the fungus to absorb the nutrients it contains. The fungus has a very wide surface area compared to its volume, which indicates that it is in close contact with its surroundings.

The given scenario would be considered "Point Source" water pollution.

Point source water pollution refers to the contamination of water bodies that can be traced back to a specific, identifiable source or location. This type of pollution occurs when pollutants are discharged directly into water bodies through pipes, drains, or other identifiable outlets.

These sources can include industrial facilities, wastewater treatment plants, oil spills, or sewage systems. Point source pollution is relatively easier to monitor and control because the source is identifiable, allowing for targeted measures to reduce or eliminate the pollution.

In contrast, non-point source pollution refers to pollution that is more diffuse and comes from multiple, widespread sources, such as agricultural runoff, urban runoff, or atmospheric deposition.

natural selection ; homologous

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!!)
