the diagram shows a bacterium. Which labels best complete the diagram

Answers

Answer:

X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm

Explanation:

A bacterium is a living thing that are majorly known for causing diseases but are important for human life.

A bacterium is also consist of several organelles such as cell wall, cytoplasm, flagellum,  bacterial DNA, cytoplasm, ribosomes and others.

The diagram shows three main organelles that are X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm. Flagella functions for the locomotion of the bacteria, bacterial DNA is a genetic material of the bacteria, and cytoplasm is a gel-like matrix composed of enzymes, water, nutrients and other waste material.

Hence, the correct answer is "X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm".

Compare the reactants and products in the chemical equations below. Which statement best describes the relation between matter and energy?

Answers

Answer and Explanation:

Chemical reactions are very complex processes which include the collision of molecules. During the chemical reactions, bonds between the breakdown of the atom and transformed in new ways. The chemical compounds that react together during the chemical reactions are called reactants, shown on the left side of the equation. They are broken down during the reaction and used as the reaction progresses. The chemical compounds that are formed from the rearrangement and breakdown of the reactants are called products. The products are shown on the right side of the chemical equation. As compare to the reactants, the products are more stable molecules. For example, in the reaction between H2SO4 and Zn, these two chemicals are the reactants, while ZnSO4 and H2 are the chemical reaction products.

                                                Zn + H2SO4       ZnSO4 + H2

                                                 (Reactants)            (Products)

The matter is a material that everything is made of matter. A property that matter has is known as energy. The same quantity of matter can have a diverse quantity of energy. Both energy and matter are identical. For example, if we add some energy into an ice cube, it will turn into liquid. After that, if we add more energy, liquid will turns into steam.

Which element has the least neutrons in the nucleus?
Aluminum
Nitrogen
Helium
Fluorine

Answers

Answer:heh

Explanation:

Aluminium , mass no = no of proton + neutron = 27

atomic no = no of proton = 13

no of neutron = 27 - 13 = 14

Nitrogen  , mass no = no of proton + neutron = 14

atomic no = no of proton = 7

no of neutron = 14 - 7 = 7

Helium   , mass no = no of proton + neutron = 4

atomic no = no of proton = 2

no of neutron = 4 - 2= 2

fluorine    , mass no = no of proton + neutron = 19

atomic no = no of proton = 9

no of neutron = 19-9 = 10

Identical, or monozygotic, twins develop from a single egg fertilized by a single sperm. Monozygotic twins are genetically identical because they originate from a single zygote that split into two. Caroline Lost and her colleagues examined nine measures of social, behavioral, and cognitive ability in 1000 pairs of both male and female identical twins. Their study found that pairs of male twins tended to be more alike in their prosocial behavior, peer problems, and verbal ability scores than pairs of female twins. Which statement explains this observation?

Answers

Answer:

Female mammals undergo X-chromosome inactivation during early embryogenesis, thereby females are mosaic for the expression of X-linked genes

Explanation:

In mammals, males receive only one copy of the X chromosome and one Y chromosome, while females receive two copies of the X chromosome. The X chromosome contains approximately 1,000 key genes involved in development. In human female embryos, one of these two copies of the X chromosome is inactivated to prevent the imbalance caused by a double dose of X-linked genes, a phenomenon known as X-chromosome inactivation. The inactivation of one X-chromosome is a random process, thereby female cells are mosaics for all heterozygous X-linked alleles, where some embryonic cells have an inactive maternal X chromosome, while other cells have an inactive paternal X chromosome.

The incidence of V. vulnificus infections is increasing, especially in northern parts of the United States, compared to 20 years ago. Can you think of any reason why this might be happening?

Answers

Answer:

The effects of climate change may be associated with the increased incidence of V. vulnificus infection

Explanation:

Vibrio vulnificus is a harmful bacterium that causes a serious disease due to eating contaminated seafood, which is the main cause of seafood-related deaths in the USA. V. vulnificus is naturally present in the flora of coastal waters around the world and this bacterium has been isolated from a variety of seafood (e.g.., fish, oysters, shrimp, etc). Epidemiologic studies have shown that the incidence of V. vulnificus infection has increased dramatically since 1996. During this same period, climate change has been responsible for the increase in salinity and temperature of the coastal waters (i.e., the natural habitat of this bacterium). In consequence, it is reasonable to suppose that the change in climatic conditions may be associated with the increased incidence of V. vulnificus infection.

Collect data: Blood carries many vital substances. Four of these are listed above the Microscopic view. Oxygen and sugar are needed by all body cells. Carbon dioxide and urea are waste products. What are the concentrations of each substance in this sample?

Oxygen:

Carbon Dioxide:

Sugar:

Urea:

Answers

Answer:

Explanation:

in the given sample of blood concentration of all the comonents is normal. the concentration of urea is 2.6 to 6.5 mM, concentration of carbon dioxide is 23-29 meq/L, while concentration of glucose ad oxygen are 0.9 g and 20.1 ml respectively.

Blood is the component of the circulatory system which is essential for the transport of gases and excretion of waste products. It is crucial for nutrient and oxygen supply to the body.

The concentration of oxygen was 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

The vital substance of blood can be explained as:

Red blood cells are called erythrocytes that are responsible for oxygen transportation through the hemoglobin component to the body parts while on their way back it carries the carbon dioxide.

Sugar is the major form of energy needed by the body for functioning which enters the blood from the liver.

Urea is the waste complement removed with the help of blood collected from the liver and excreted by kidneys.

Therefore, the normal concentration of blood substances is oxygen 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

If your nose is completely clogged and you try to blow it out, you are generating pressure from your lungs. a. The smaller your nasal passage, the less force the pressure from your lungs will exert on the clog. b. The smaller your nasal passage the more force your pressure will exert on the clog. c. The size of the nasal passage does not affect the force your lungs exert on the clog.

Answers

Answer:

The correct answer is - option A. The smaller your nasal passage, the less force the pressure from your lungs will exert on the clog

Explanation:

Velocity depends on the area of the passage and directly affected by this as velocity is inversely proportional to the area of the passage, therefore, the lesser the nasal passage area higher will be the velocity.

v=Q/A

By this it is clear that the required pressure will be less and velocity will be more and less pressure generated from the lungs.

The correct answer is - option A.
