b) Keep the jars in sunlight and water them regularly.
c) When the plants grow from the seeds then close one
jar and observe for 2-3 days.-
What do you observe? Write in your notebook?

Answers

Answer 1

The plant in the closed jar will die eventually due to lack of oxygen.

The plant in the jar that is not closed will live and grow.

In the absence of oxygen the plant will be unable to perform photosynthesis.

What is photosynthesis?Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Productivity of agricultural crops directly depends upon the rate of photosynthesis.

Explanation:

Isomers with the same molecular formula.  The molecular formula gives a list of the type and quantity of each element in a molecule.

In other words, they are two different molecules with the same type and amount of atoms. The difference is that their structures are different. That being said, the structural formula of the molecules would not be the same. Hydrocarbons are molecules that only consist of carbon (C) and hydrogen (H) atoms.

Why does the Department of Homeland Security target foot-and-mouth disease?

Answers

The bottom- and- mouth complaint contagion has been honored since at least the 16th century.

It's characterized by fever, pocks on the bases and mouth, loss of appetite, drooling and lameness. Infected herds of creatures are generally destroyed.

Large quantities of the contagion are present in all body concealment, including breath, and are readily transmitted to other creatures. The contagion can also survive on the ground for extended ages of time and can be transferred on tires, thrills and clothes. It has indeed been shown to be carried long distances by wind.

The United States has been free of the complaint since 1929, but that isn't a guarantee it'll not return. Britain was free of the complaint for 34 times before a 2001 outbreak that needed the destruction of 10 million cows.

FMD contagion is largely contagious in cloven- mashed creatures, including cattle, gormandizers, small ruminants. Encyclopedically, FMD has a significant impact on beast trade economics and expansive nonsupervisory programs live in the U.S. to grease identification of, response to, and control of the complaint. With one in nine Americans employed in the husbandry or confederated diligence, the goods of an FMD outbreak in the U.S. would be ruinous ­ – estimated at nearly$ 200 billion in lost profit over 10 times across affected diligence.

Therefore the Department of Homeland Security target foot-and-mouth disease.

Which kind of mutation is most likely to lead to a new trait in an organism?

A. A frameshift mutation

B. A nonsense mutation

C. A missense mutation

D. A silent mutation

Answers

A frameshift mutation is a kind of mutation which is most likely to lead to a new trait in an organism. Thus, the correct option is A.

What is Mutation?

A Mutation may be defined as the sudden, stable, and inheritable alterations in the genomic sequence of an organism.

A frameshift mutation occurs when the reading frame modifies the grouping of the bases and thereafter transforms the amino acids that are encoded. Here, the encoded protein is non-functional.

A missense mutation arises when there is a blunder in the DNA code and one of the DNA base pairs is altered.

A nonsense mutation occurs when a single change in the base sequence outcomes in the exhibition of a stop codon, thereby concluding protein synthesis prematurely.

Therefore, it is well described above.

How does someone achieve a unified self?

Answers

Answer:

please mark me as brain list

Explanation:

The unified self is a flawed construct. Experience changes us, even at the core. People change us just by being with us. It doesn't have to be a long term relationship. Our minds may not have the plasticity they once had but we adapt daily to the people around us and, in a slower fashion, tide rather than waves rather than ripples, we the ebb and flow of experience changes the "I think" that creates our values and judgements, which changes the experiences we seek then have which again works on the way we view the world.

A possible reason we are able to change when we are with different types of people is that we have a certain number of roles at our disposal. I've noticed this, on an extreme level, with some coworkers. I wondered how they could change so much when they got to the office. They'd suddenly become very business-like and at first I thought they were play acting. They were, in a sense, but I believe their identity changed when they walked through the office door. They were no longer the guy or girl I'd just ridden to work with, they were such and such part of the hierarchy and their behavior wasn't all a put on, though some of everyone's behavior in every role is, it was who they were then.

It took being asked to take a work related personality test that clued me in. The test results came back. One part of results outlined our scores for introversion/extroversion scores at home and at work. The scale was -50 to +50 where the score determined one's level of introversion (-) or extraversion (+). I scored -33 at home and a +33 at work. The automatic scoring algorithm suggested that it was likely I was under a lot of internal stress because of this. I was. I used to have dry heaves when I transitioned from work to home. That part of the results wasn't the only part rang true though so I took it seriously.

How close the roles we play with different people are to each other might be an indicator of how unified we are. If you were to scale our unification factor from 0 to 1 I would have been considered a 0.33 based on my introversion/extraversion scores, if that was the only score that mattered. More things the behavior than others matters, of course. Perhaps people who are very different in differing situations experience more cognitive dissonance. It would be interesting knowing.

One can achieve a unified self when the ego desire of the self and the altruistic urge of the higher self are co-ordinated and reconciled by the unified will of different personas.

What is Unified self ?

A person's "composite" persona, also known as the "self" that incorporates all of the other personalities present in their interactional style, is referred to as the "unified self ."

The majority of cognitive scientists and brain specialists hold that the self is not a single, cohesive "thing," but rather a collection of distinct modules or mental systems.

Our perspective of oneself could readily alter if we are exposed to a logical argument that may modify our perception because it is merely a collection of separate modules.

Therefore the concept of achieving a unified self is still unclear and psychologists are constantly looking for an answer regarding same.

Factors affecting photosynthesis Leaf covered with aluminium foil

Answers

Answer:

This leaf will not undergo photosynthesis

Explanation:

Factors influencing photosynthesis are light,temperature, carbon dioxide and water and since the plant lacks light photosynthesis is inhibited

Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the electron transport chain of photosystem II. Once atrazine binds to the proteins, electrons can no longer travel down the chain to reach photosystem I.

Based on this information, how does atrazine stop plant growth?

A.
It prevents water from releasing oxygen, which is needed by the light-dependent reactions to fix carbon.
B.
It prevents the formation of NADH and FADH2, which are needed by the light-independent reactions to fix carbon.
C.
It prevents chlorophyll from creating electrons, which are needed by the light-dependent reactions to make sugars.
D.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.

Answers

It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.

The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.

 

What are herbicide?

Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.

This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.
