Sometimes a mutation is beneficial to organisms fitness in can be passed onto the offspring. What is likely to happen to the mutation over many generations?

A. Any genetic variation will not persist because the mutation is a one time event.

B. There is a random chance of the mutation spreading to other individuals in the population.

C. The mutation will become more common in offspring and increase the genetic variability in the gene pool.

D. Genetic recombination is the only way that variations can be passed on so the mutation will die out.

Answers

Depends on the type of genetic mutation it is 
I believe that the answer could either be A or C. Sorry I cannot be of more help

Answer:

C. The mutation will become more common in offspring and increase the genetic variability in the gene pool.

Explanation:

The mutation which is beneficial to the organism's fitness occurs in the genetic cell of the individuals and after the fusion with the opposite gametic cell during fertilization it passes to the offsprings.  

So these offsprings reproduce the mutation will pass to some more offsprings and like this mutation will become more common in the population which will result in increasing the genetic variability of the in the gene pool. So the correct answer is C.

how is lactic acid produced?

Answers

naturally and synthetically 
Final answer:

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.

What organism or organic matter gave rise to coal?

Answers

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.

In which environment would primary succession take place? Check all that apply.

an abandoned field
a cooling lava flow
a valley under a glacier
an unused farm
a burnt forest
a deserted mine

Answers

Primary succession happens in a place where there is no soil cover or it is removed.

an abandoned field- Secondary; because there is cover of soil left, even if vegetation is removed.  

a cooling lava flow- Primary; volcanic events lead to loss of soil layer, so this would lead to primary succession  

a valley under a glacier- Primary; retreating glaciers are lead to primary succession  

an unused farm-Secondary; the soil cover is still present

a burnt forest- Secondary; soil cover is still left for vegetation to start over again

a deserted mine- Primary; because there would be barren rocks left, so soil would be formed by pioneer species first.

Answers

Hi there!

When a few individuals are isolated from the rest of the population and can have very different gene frequencies, it is called the Founder Effect. The founder effect is a type of genetic drift in which a small population is isolated. Due to this isolation, the population may have different gene frequencies than the rest of the larger population.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

The relative frequency of the gene variant expressed as per cent or fraction is called gene frequency. The isolation and the varying gene frequency is due to the Founder's effect.

What is Founder Effect?

The loss of the genetic diversity in the new population of the organism that diversified and got isolated from the ancestral population.

This effect depicts the variation in the gene frequencies when the few organisms are isolated from the rest of their population. It can be said as a type of genetic drift in which the allele frequencies of the older population and the new population of the same organism gets differed.

Therefore, the Founder effect is the variation of the gene frequencies in the isolated population.

Flourine 23 has a half-life of 2.2 seconds. how much of a 400 g sample would be left after 11 seconds ?

Answers

12.5 grams of Flourine 23 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.

Toxicodendron rydbergii is the scientific name for western poison ivy. Toxicodendron radicans is the scientific name for eastern poison ivy. Which of the following statements are true?

Answers

the answer(s) is

Western and eastern poison ivy belong to the same class.
Western and eastern poison ivy are part of the same order.

The genus Toxicodendron includes both western and eastern poison ivy.

Answer:

Western and eastern poison ivy belong to the same genus.

Explanation:

The scientific name of the species was created in order to create a universal nomenclature for living beings. This way, scientists in Brazil, for example, could talk to scientists in Africa and Japan about the same living thing without creating confusion about names. In short, the scientific name is accepted by all languages and all dialects and idomous expressions.

The scientific name is formed by two words in Latin. The first word refers to the genus to which the organism belongs, the second name refers to the specific epithet. The two names together form the species name.

For this reason, we can say that if Toxicodendron rydbergii is the scientific name for western poison ivy and Toxicodendron radicans is the scientific name for eastern poison ivy, western and eastern poison ivy belong to the same genus.

Gender, age, heredity, race, and the environment all examples of uncontrollable risk factors.

Hope the helps!!

Gender, age, heredity, race, and the environment are all significant factors that influence various aspects of human health. These elements can affect the likelihood of developing certain diseases, physical and mental health outcomes, and the effectiveness of treatments. It is essential to recognize how each factor individually and collectively impacts health to improve health outcomes and strategies.

Gender can influence health due to biological differences and social roles that affect exposure to risks and health behaviors. Age is a critical determinant as the risk for many health issues increases with age. Heredity plays a vital role because genetic predispositions can affect the likelihood of certain conditions. Race can affect health due to both biological diversity and differences in socio-economic factors that contribute to health disparities. Lastly, the environment encompasses physical, social, and economic conditions that can have significant health impacts. Understanding these factors is paramount in developing public health policies, prevention strategies, as well as individual health plans. Only by considering each of these can a comprehensive approach to health care be achieved.

Identify two things organisms compete with one for another

Answers

Two things organisms compete with each other for are food and females/males to mate.

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.
