The answer is option B. The number of protons
If two atoms are isotopes of the same element then the number of protons in those two atoms must be same but the number of neutrons must not be same. If number of neutrons of an atom vary but number of protons in them are same then it simply means that they both are isotopes of a particular element. As we know that every atom has a nucleus which has protons and neutrons and due to these protons and neutrons an atom has weight. Apart from that, an atom has electrons too but they are outside the nucleus. Electrons are extremely light in weight so they do not contribute towards weight but they have a great role in chemical reactions. During chemical reactions, it is electron which directly participates, while proton and neutrons do not take part or move during chemical reactions. Also, in a neutral atom number of protons is equal to number of electrons but when an atom becomes negatively or positively charged, it can gain or loose electrons so electrons have tendency to vary. That is why we cannot consider electrons to be always same for isotopes of an element. It is clear that for an isotope, the number of electrons and neutrons will vary but the number of protons will always be fixed.
Isotopes of an element are atoms of the same element with the same number of protons but different numbers of neutrons. So, the number of protons in the atoms right answer.
Explanation:The correct answer for this question is B. The number of protons should be the same for two atoms to be considered isotopes of the same element. Isotopes are different forms of the same element that have the same number of protons, but a different number of neutrons. This means that they are in fact the same element, as the number of protons in an atom determines what type of element it is. Regardless of whether an isotope is radioactive or stable, it will still have the same number of protons as the original element. The number of electrons or molecules do not determine isotopic identity.

The period of time imprinting occurs is the
A. Fear period
B. Training period
C. Sensitive period
D. Socialization period
The time period during which imprinting occurs is the 'sensitive period'. It is a specific time right after birth or hatching where an animal learns to recognize its own species. This behavior often affects their behaviors later in life.
Explanation:The period of time during which imprinting occurs is the sensitive period. Imprinting is a rapid form of learning that occurs in a specific time period, usually soon after birth or hatching, which enables an animal to recognize its own species. It often determines behaviors later in life. The concept of the 'sensitive period' in imprinting was proposed by ethologist Konrad Lorenz. He showed that the rapid learning process happens in a limited, very specific period of time, making imprinting a phenomenon of the sensitive period.
To differentiate between options, a fear period is a time of particular sensitivity to fear stimuli, often seen in young animals. The training period is rather a human-defined concept for when learning might be most effective, and the socialization period refers to the period when social skills and behaviors are learned, but those are not exclusive to imprinting.

how is lactic acid produced?
Lactic acid is produced during lactic acid fermentation, a process used by certain bacteria and animal muscle cells under low-oxygen conditions, catalyzed by lactate dehydrogenase. In muscles, lactic acid is transported to the liver for conversion back into pyruvic acid for energy.
Explanation:Lactic Acid Fermentation
Lactic acid is produced during a process known as lactic acid fermentation. This process is carried out by certain bacteria, such as those found in yogurt, and by animal muscle cells, like those in humans, during intense physical activity when there is not enough oxygen available for aerobic respiration. The key chemical reaction in this process is Pyruvic acid + NADH → lactic acid + NAD+, and it is catalyzed by the enzyme lactate dehydrogenase (LDH). In muscle cells, this process allows them to continue producing energy even when oxygen levels are low, although it can lead to the temporary accumulation of lactic acid in the muscles. Ultimately, the lactic acid must be transported via the blood to the liver, where it can be converted back into pyruvic acid and used for further energy production.

Groups of skin cells form the epithelium, which lines organs and cavities in the body. The epithelium is MOST LIKELY a kind of A) cell. B) organ. C) tissue. D) organ system.
Answer:
C) tissue.
Explanation:
The epithelium is a tissue.
Epithelial tissue is one of the four basic types of animal tissue. Formed by juxtaposed cells, among which there is little extracellular substance. Since your cells have no blood vessels, nutrients are received through the underlying connective tissue.
The lining epithelial cells are joined with each other through structures called cell junctions. The various types of junctions serve not only as adhesion sites, but eventually also as seals preventing the flow of materials through the intercellular space, and they can also offer channels for communication between adjacent cells. Therefore, from a junctional point of view, junctions can be classified as adhesion junctions, tight junctions and communication junctions (gap junctions). In many epithelia several junctions are present in a constant sequence from the apex to the cell.

How will doctors most likeling respond to someone who has an active case of drug resistant tuberculosis
Answer: Doctors will still use other drugs that are known to treat tuberculosis, even if they are less effective than the common drugs.
Tuberculosis (TB) is a disease caused by bacteria that are spread through the air from one person to another. TB affects not just the lungs, but other parts of the body (the brain, the kidneys, or the spine). In most cases, TB is treatable and curable; however, sometimes drug-resistant tuberculosis occurs when the drug can no longer kill the TB bacteria. In such case, doctors will use other drugs that are known to treat TB, even if they are less effective than the commonly available drugs.

Identify two things organisms compete with one for another
All organisms require resources to grow, reproduce, and survive. All the resources are limited. Hence, organisms compete to get the resources. Competition is an interaction which takes place among organisms whenever two or more organisms require the same limited resource.
Ecological interactions can be intra-specific or inter-specific. Intra-specific interactions are those that occur between individuals of the same species, while interactions that occur between two or more species are called inter-specific interactions.
Competition between organisms plays an important role in ecology and evolution, it serves to limit organism population and thereby ensure its sustainability and survival.

why is proper agricultural management and distribution of food necessary
Answer:
Explanation:
Agriculture solely is responsible for the source of food, shelter and clothing in our modern world. It has been so since pre-historic times. The role in which agriculture plays has further been expanded to capture newer dimensions.
Proper agricultural management and distribution of food helps to alleviate the problem of food shortages in societies today. Most growing communities are located in hinterlands due to the availability of land for farm practices. If produce fails to reach the buying and dependent communities, there would be acute food shortage. To the farmers, they will incur loss through spoilage of produces.
Proper management bridge this gap.

What organism or organic matter gave rise to coal?
Coal is formed from plant vegetation. When this organic matter accumulates (layer after layer) in water-logged region, over time it forms peat (partly decomposed matter in acidic boggy ground). When the peat gets buried down under a column of sediments (over time), the high pressure and temperatures convert the peat to coal.
The organism is bacterial
Coal is known to be black solid combustible fossil fuel that is made up of carbon based material which is about 50% of its weight. The process of coal formation begins with the decomposition of plant matter by bacterial. The two main phases in coal formation are peatification and coalification, however, bacterial activity creates peat during peatification while increasing the temperature and pressure is refers to as coalification.

Flourine 23 has a half-life of 2.2 seconds. how much of a 400 g sample would be left after 11 seconds ?
Given: Flourine 23 has a half life of 2.2 seconds. Amount of Flourine 23 present at the beginning is 400 gm.
To find: The amount of Flourine 23 left after a duration of 11 seconds.
Solution:
The number of half-lives that 400 gm of Flourine 23 has to go through can be found by the following way,
[tex] \frac{T}{T_h_a_l_f_-_l_i_f_e} = \frac{11 seconds}{2.2 seconds} = 5 [/tex]
So the 400 gm of Flourine 23 will undergo 5 half lives and with each half-life the amount gets divided by 2 or reduces by half.
400 gm -> 200 gm -> 100 gm -> 50 gm -> 25 gm -> 12.5 gm
∴ 12.5 gm of Flourine 23 will be left after 11 seconds.
