What cell type are involved in the secretion thyroglobulin ?
By thyroid epithelial cells and secreted into the lumen of the follicle - colloid is essentially a pool of thyroglobulin.
What is Thyroglobulin?The amount of thyroglobulin in a sample of your blood is measured by a thyroglobulin test. Your thyroid produces a protein called thyroglobulin. A little gland in your neck with a butterfly form is your thyroid.
It produces hormones that regulate a variety of bodily functions, such as your heart rate and how quickly you burn off calories from food.
One kind of test for tumor markers is the thyroglobulin test. In reaction to cancer in your body, cancer cells and/or normal cells produce molecules known as tumor markers. Small levels of thyroglobulin are typically released into your bloodstream by your thyroid.
Therefore, By thyroid epithelial cells and secreted into the lumen of the follicle - colloid is essentially a pool of thyroglobulin.

Q
Which traits should the student put in section II (Both)?
O a scar and blood type
tiger's stripes and wolf's social status
musical talent and wolf's social status
musical talent and skin color
Answer: a scar and wolf's social status
Explanation:
The acquired traits can be defined as the traits, which are only influenced by the environment of the organism. The acquired trait cannot be passed down to the offspring, as they are not genetically determined. A scar and the social status of any organism is dependent on the behavior of the organism to the environment, no genes code for both of these characters. So, scars and Wolf's social status is an acquired trait.
The trait that should be put in section II (Both) is "a scar", as scars can be acquired due to injury or trauma, but some people may also have a genetic predisposition to scarring.
What are inherited and acquired trait?Inherited traits are characteristics that are determined by an individual's genetic makeup and are passed down from parents to their offspring through the process of reproduction. Examples of inherited traits include eye color, hair color, blood type, and facial features.
Acquired traits are characteristics that are developed during an individual's lifetime as a result of their interactions with the environment. Examples of acquired traits include scars, calluses, tanned skin, learned behaviors, and language proficiency.
While some traits may be either entirely inherited or acquired, many traits are influenced by both genetic and environmental factors. The complex interplay between nature and nurture contributes to the vast diversity of traits and characteristics found within the human population.

what is going to be affectedwhat is being testedwhat is being observed or measured
you have selected the following prediction to test: Previously thinned forests will have higher tree survival than adjacent forests that were not thinned. Now you need to define the key variables that you will use to test this prediction. For the following variables, sort them as independent variables, dependent variables, or variables that should be controlled (held constant)1. thinning or no thinning before the fire elevation of the site 2. dominant tree species 3. tree survival rate after the fire A. Independent variableB. Dependent variable C. Controlled variable
Answer:
A. Independent variable 2. dominant tree species
B. Dependent variable 3. tree survival rate after the fire
C. Controlled variable 1. thinning or no thinning before the fire elevation of the site
Explanation:
A. An independent variable doesn't undergo changes during the experiment because it is not conditioned by other variables in the experiment. In this example, dominant tree species represent a variable that is independent of the experiment itself.
B. A dependent variable is those that you need to measure and depends on the other factors in the experiment. In this example, tree survival is dependent on the factors that affect the results (i.e. humidity in the trees, presence of resinous material in the trees that are non-combustible, etc.)
C. A controlled variable is those that we use to observe an expected outcome in the experiment and therefore it is used to compare with the test group. In this case, thinning or no thinning are used as positive and negative controls, respectively, because they enable their comparison with the test group in the experiment.

B. In maternal effect, an offspring will have the genotype of their mother.
C. In a reciprocal cross, if an offspring has the mother's phenotype for both crosses, cytoplasmic inheritance is responsible.
D. The direction of shell coiling in Lymnaea peregra is influenced by the orientation of the first cleavage division.
E. It is safe to say that a maternal effect is caused by the genotype, not the phenotype, of the parent producing the egg.
Answer:
Answer is D.
Explanation:
The first cleavage division can be explained or described as the series of first cellular division of the zygote after fertilization.
In this case, the process of recoiling of the shell of the snail can not be categorized as one of the examples at this stage.

O It is degraded.
O It is sliced into different sections.
Answer:
it binds together
Explanation:
dna is commonly present in the shape of a molecule with double strands. In a similar way, these two molecules connect to each other in a mechanism called hybridisation. DNA naturally, the new strand hybridizes to the old strand when it is replicated.
hope this helped!
During hybridization, DNA strands bind together. The correct option is A.
The process of joining two complementary strands of DNA from various sources to create a double-stranded molecule is referred to as hybridization.
The complementary DNA strands join together during this phase and create strong hydrogen bonds between their corresponding base pairs. Adenine (A) and thymine (T) and guanine (G) and cytosine (C) couple up specifically to form this interaction.
Numerous molecular biology procedures, including DNA hybridization tests, polymerase chain reaction (PCR), and DNA sequencing, frequently employ hybridization.
Hybridization enables the identification and amplification of particular DNA sequences as well as the analysis of genetic data by allowing the complimentary strands to come together.
Thus, the correct option is A.

Diffusion is a passive process that accounts for the movement of respiratory gases across the capillary membranes of alveoli.
True
False
Answer:
True
Explanation:
Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.
During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.
Hence, the given statement is true.

Answer:
The medullary cavities are found deep in the diaphyses of long medullary cavities bones and are filled with yellow marrow in the adult.
Osteocytes maintain contact with neighboring osteocytes in adjacent lamellae via dendrite-like extensions through canaliculi.
Filled with osteocytes, which are osteoblasts encased in matrix, lacunae are found between layers of concentric lamellae.
Located in the middle of osteons, the central canal contain the blood vessels, and nervous supply of the compact bones
Explanation:
- The medullary cavities are central cavities in the bones. In adults, these cavities are filled with yellow marrow (adipose tissue).
- The canaliculi are small protoplasmic projections between the lacunae of ossified bones.
- The astrocytes are the most common type of bone cell.
- The lacunae are spaces where osteocytes are located in the mature bones
- The central canal provides nourishment to the osteocytes which collectively form the osteon.
You are monitoring the metabolism of two different cultures of the same species of yeast, which you have labeled Culture A and Culture B. One of your observations is that Culture A is using up about 10 times the amount of glucose per unit of time as Culture B. Which one of the following conclusions could you reasonably draw regarding these cultures?
A. Culture A would be accumulating lactic acid.
B. Culture A is being grown aerobically; Culture B is being grown anaerobically.
C. Only Culture A is recycling its NADH back to NAD+.
D. Culture A and Culture B are synthesizing the same amount of ATP per unit of glucose in glycolysis.
E. None of the above conclusions could be drawn from the information given.
Answer: D
Explanation: The experiment was set up using the very same species of yeast labeled differently. What this means is that they are of the same type or kind and thus would exhibit similar features from feeding to the metabolism of the food they take and subsequent production of by-products of the fermentation process. In this regard, therefore, the reasonable conclusion that can be drawn regarding these cultures is that both cultures A and B are synthesizing the same amount of ATP per unit of glucose in glycolysis (the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source).

Predict which one of the following organisms will have the highest percentage of unsaturated fatty acid chains in their membranes: Group of answer choices thermophilic bacteria desert iguana humans antarctic fish
Answer:
Humans
Explanation:
Humans are bigger than most beings and some people are extremely obese.
The organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.
Unsaturated fatty acid chains have one or more double bonds, while saturated fatty acid chains do not contain any double bonds.When the temperature decreases, the composition of the phospholipids bilayer membrane becomes more unsaturated to be able to maintain different properties such as homeoviscosity.In consequence, membrane lipids exhibit the highest percentage of unsaturated fatty acid chains during cold acclimation.In conclusion, the organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

six ways are temperature,coastal communities,food,shipping,wildlife,permafrost
Answer:
Explanation:
Artic Ice are melting due to change in the climatic system as a result of global warming. The active increase in human activity resulting in global warming will continually perpetuate the decrease in artic Ice.
Artic heat help to balance temperature or heat on the earth surface by reflecting heat back into the environment. When the artic Ice is reduced, the amount of heat reflected is also reduces.
Coastal community - a continuous rise in ocean level can lead to flooding which will affect the coastal community surrounding the ocean. An the ocean has been incredible gradually over the pass decades.
Food - Reduction in the artic Ice car Lea to increase heat affect crop growth through damage by heat stresses leading to an increase price rate of food.
Meltng of Ice increase the shipping routes causing more harm through ship wrek.
Melting of Ice can leave to loss of animals that depends on it for survival.
Permafrost occurs when the ground is permanently block or frozen leading to accumulation of methane gases that causes global warming.

The bond that forms between two glucose molecules are called
1. Peptide bonds
2. Ester bonds
3. Phosphodiester bonds
4. Glycosidic bonds
5. Hydrogen bonds
Answer:
Glycosidic Bonds
Explanation:
Glycosidic Bonds are a type of covelant bond that form between two or more 5 carbon sugar macro-molecules(like glucose). Hydrogen bonds are an attraction between hydrogen atoms, not a real sharing or trading of electrons, as seen with ionic and covelant bonds, while they are essestial to life in water, they generally do not have a strong effect in the building of macromolecules. Therefore, that is incorrect. Phosphodiester, ester, and peptide bonds all occur between different macro-molecules, none of which include glucose(5 carbon sugar). Therefore, the answer is #4.
