Answer:

It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals

Explanation:

Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.

Answer:

The stomach and the teeth both perform mechanical digestion, which is physically (as opposed to chemically) breaking the food into smaller components. This exposes a larger surface area for chemical digestion and release of nutrients. The teeth are vital to mastication, which breaks large bites of food down into smaller pieces that are easily swallowed. The stomach’s muscle contractions churn the food to expose all particles to the acid and digestive enzymes..

Answer:

According to the given question that without prior knowledge on the prodigiosin synthesis pathway of these Serratia species, and we experience two different color morphs of the species. So, there is given or known preliminary morphological basis we will consider them different two different colonies. These can be identify only after genetically identify or study.

The morphological characterstics of the organism and the genetic identification both are equally important. So Giving any one more importance over other is not logical.

Morphologically we can differentiate the color of the colonies of mutants. The mutant serratia sp. are  known for eficient biosynthesis of prodigiosin, Thus on the basis of color characteristics of their colonies when grown on peptone glycerol medium we can identify.

Answer:

I think it's A

must lie btn a clearly defined interval

Continues variable must be between a clearly defined the interval about continuous variables. Thus,option A is correct.

A continuous variables is define as a function which continuous varies in a given interval for instance, if a variable over a non-empty range of the real numbers is continuous, then it can take on any value in that range.

Types of continuous variables:

There are two types of continuous variables which are mentioned below:-

1:- Instant variable

2:- Ratio variable

Instant variable

A variable can be defined as the distance or level which are varies between given interval.

Ratio variable

Ratio variable is another type of continuous variables which has only one variation in given interval.

Therefore, continues variable must be between a clearly defined the interval about continuous variables. Thus, option A is correct.

Answer:

1. Connects the larynx to the main bronchi k. trachea

2. Includes terminal and respiratory as subtypes b. bronchiole

3. Food passageway posterior to the trachea. e. esophagus

4. Covers the glottis during swallowing of food d. epiglottis

5. Contains the vocal cords g. larynx

6. Indentation on the lung where the lung root structures enter and exit f. hilum

7. Pleural layer lining the walls of the thorax j. parietal pleura

8. Site from which oxygen enters the pulmonary blood a. alveolus

9. Connects the middle ear to the nasopharynx. i. pharyngotympanic tube

10. Pleural layer in contact with the surface of the lung l. visceral pleura

11. Increases air turbulence in the nasal cavity c. conchae

12. Separates the oral cavity from the nasal cavity h. palate

Explanation:

1. The trachea is between the main bronchi and the larynx. It has semicircular rings of cartilage. The function of this organ is to conduct the air from the larynx to the primary/main bronchi.

2. After the primary (main), secondary, and tertiary bronchi, the terminal and the respiratory bronchioles come. They also conduct the air towards the alveoli so that the oxygen can enter the blood. The diameter of the bronchi terminal is smaller than the bronchi, and the diameter of the respiratory bronchi is smaller than the previous ones.

3 and 4. The esophagus is not part of the respiratory system. It is a tube that belongs to the digestive system since food has to pass through it to go to the stomach. The esophagus is posterior to the trachea, and the epiglottis closes the entrance to the larynx when we swallow to stop food from going to the lungs.

5. The vocal folds are in the larynx. This one is between the trachea and the pharynx. There are two types of vocal folds, the true and the false vocal folds. Both of them vibrate when air passes through them, allowing us to speak and make different tones.

6. The hilum is the lungs section where the bronchus, the pulmonary artery, and the pulmonary vein enter the lung. It is an indention that is in the middle part of the lungs.

7 and 10. The pleura has two sides, the parietal one and the visceral one. The first one is in contact with the lungs and the second one with the thorax's walls. Between them, there is a space called the pleural cavity. The cavity has fluid that allows the movement of the two pleurae. As a result, the lungs can move and fill with air.

8. After the respiratory bronchioles, we have the alveolar duct. The alveolar ducts lead to alveolar sacs. The alveolar sacs has the alveolus. They are thin walls that are in contact with capillaries. When the air is there, the oxygen passes through the thin walls. Then it goes through the capillaries' walls and into the blood.

9. The pharyngotympanic tube is also known as the Eustachian tube. It connects the middle ear to the nasopharynx. Its function is to regulate the pressure in the ear.

11. The conchae are in the nasal cavity. They are three projections in the nasal cavity, the inferior one, the middle one, and the superior. Their function is to increase the surface of the nasal cavity so that more air can enter with every inspiration. As they are projections, they modify the laminar airflow producing a turbulent flow.

12. The palate is between the nasal cavity and the oral cavity. It has two parts, the soft palate, and the hard palate. The palate helps in the production of certain sounds and divides the nasal cavity from the mouth.

Answer: B) because in higher plants, such as angiosperms and gymnosperms, the sporophyte is the dominant generation.

All of the following statements about ferns are correct except the gametophyte is a conspicuous generation. Therefore, the correct option is D.

In ferns the gametophyte is usually much smaller and less noticeable, whereas the sporophyte is the more noticeable generation. The sporophyte, the famous giant pearl fern plant, is a major stage in the fern life cycle. Gametes (eggs and sperm) are produced by the gametophyte, which is a small, autonomous stage responsible for sexual reproduction.

Therefore, the correct option is D.

Answer:

it should be an true statement

Answer:

True

Explanation:

Nitrogen is a fundamental component of both inorganic and organic compounds, where it is the main constituent of biomolecules such as nucleic acids (DNA, RNA) and proteins. The nitrogen cycle refers to the biogeochemical processes by which nitrogen circulates between the components of an ecosystem, i.e., between organisms (like plants and decomposers), and non-living things (i.e., soil, water, air). This cycle consists of several processes which include, among others, nitrogen fixation (i.e., the process by which nitrogen in the atmosphere is converted into ammonia), nitrification (i.e., the oxidation of ammonia is oxidized into nitrite and subsequent transformation of nitrites into nitrates), denitrification (where nitrate is reduced), anaerobic ammonia oxidation and putrefaction.

Answer:

Reducing the intensity of runoff.

Explanation:

Terrace farming prevent landslides and erosion to occur by reducing the intensity of runoff. This farming also reduce the risk of drought due to raising the moisture content in the soil and allowing water to slowly infiltrate into the soil. Due to terrace farming, the runoff water moves very slowly which causes less erosion of the soil as well as reduces the intensity of water flow which causes more infiltration.

Answer:

cà chua

Explanation:

Answer:

Due to lack of expansion of lungs.

Explanation:

The lack of surfactant compound would result in respiratory distress because Surfactant enables the lungs to expand more easily which allows easiness in respiration. Without surfactant, the air sacs in the lungs will collapse very easily. This collapse leads to decreased amounts of air or oxygen in the lungs which makes it very difficult for the people or infant to breathe.
