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:

c) small plants grow but eventually replaced by larger plants.

In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.

The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.

In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.  

Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.

Answer:

1-The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

2-The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.

3-The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.

4-The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.

5- i havent seen the video then how can i answer q5

The answer of this query is discussed below:

The Calvin cycle converts airborne carbon molecules directly into plant material. Because plants are the foundation of the energy pyramid in most ecosystems, the Calvin cycle is crucial to their survival.

The carbon atoms needed for photosynthesis to create sugars are found in carbon dioxide. RuBP is initially combined with carbon dioxide, and RuBP is then renewed to complete the Calvin cycle.

Answer:

D. High Life Expectancy

Explanation:

Air pollution lowers life expectancy and causes tons of premature deaths in areas. The area that Alan lives in has good air quality which means that there is obviously going to be a increase in life expectancy. If water quality is bad in an area it can cause chronic illnesses (such as cancer), gastrointestinal illnesses, and even effect the nervous and reproductive systems in a bad way. So the fact there is good water quality in the region the area Alan lives in, he is pretty much guaranteed for higher life expectancy. Therefore the best answer is Option D.

Answer:

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!!)

(this = 0.6)

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.

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.
