Which one of the following discoveries involving DNA happened first?

Answers

Answer 1
Answer: In 1944, Oswald Avery identifies DNA (Deoxyribonucleic Acid) as transforming principles. This famous genetic scientist has made great efforts for many steps to find what happened after combinations of some bacteria. After purification, he found a new substance which was a nucleic acid, involving the discovery of DNA after further analysis.

After suffering an accidental brain injury, Kira has difficulty walking in a smooth, coordinated manner. It is likely that she has suffered damage to her:

Answers

Answer: Kira has difficulty in walking in smooth coordinated manner because she has suffered injury to the cerebellum.

Explanation:

Cerebellum is a part of the brain situated inferior to cerbrum and posterior to pons. It receives sensory information and converts it into motor responses. Motor coordination is when subsequent parts of the same movement, or the movements of several limbs or body parts are combined in a manner that is well timed, smooth, and efficient. Cerebellum coordinates voluntary motor movements resulting in smooth coordinated muscular activities. Injury to cerebellum causes its loss of function which in return causes

1) loss of coordinated movements

2) inability to perform alternate rapid movements

3) movement tremors

4) staggering wide based gait

Final answer:

Kira likely damaged her cerebellum, as this part of the brain regulates fine motor control and coordination. Damage can lead to ataxia, characterized by unsteady, uncoordinated movements.

Explanation:

After suffering a brain injury and having difficulty walking in a smooth, coordinated manner, it's likely Kira has suffered damage to her cerebellum.

The cerebellum is part of the brain responsible for fine motor control, balance, and coordination. Damage to this area can result in ataxia, a type of movement disorder characterized by a lack of muscle control during voluntary movements, leading to unsteady and uncoordinated walking.

Which best describes the difference between osmosis and diffusion

Answers

Osmosis is the specific movement of solvent molecules through a semi-permeable membrane, while diffusion is the general movement of particles from high to low concentration in any medium.

Osmosis and diffusion are both fundamental processes of passive transport. Osmosis is a subset of diffusion that specifically involves the movement of solvent molecules, usually water, through a semi-permeable membrane to equalize solute concentrations on both sides of the membrane. It's essential in processes like maintaining cell turgidity.

On the other hand, diffusion encompasses the broader concept of particles, including solutes and gases, spreading out from areas of high concentration to low concentration. It occurs in various environments, not limited to membranes, and is vital for processes like gas exchange in respiration and the distribution of nutrients in cells.

pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).

Which is the main light-absorbing pigment for photosynthesis?carotene
chlorophyll
hemoglobin
anthocyanin User: Which is an example of why the process of photosynthesis is important to life on Earth?
Grass uses photosynthesis to produce glucose, which is used within the grass for growth.
Fungi use photosynthesis to decompose dead and decaying plant matter.
Cold-blooded animals use photosynthesis to convert sunlight into energy for cell functions.
Green plants use photosynthesis to ...

Answers

Photosynthesis is carried out in the chloroplasts which contain the green pigment chlorophyll. Chlorophyll is what gives plants their characteristic color and it works by capturing the energy that is in the sunlight that strikes the plant. Photosynthesis is important to life on Earth because grass uses photosnthesis to produce glucose, which is used within the grass for growth. Subsequently, organisms that consume the grass obtain energy and so on. Therefore, photosynthesis is the process through which energy enters an ecosystem.

the answer is chlorophyll

If you flipped a penny 99 times and each time it came up heads, then the chance of the penny coming up heads again is ____ . 50% 1% 100% 25%

Answers

The chance of coming up heads 99 times in a row is abysmally small: 50%^99 = 1.57 * 10^-30.This however has already happened, it does not influence the next penny flip.A penny has two sides, so the chance of it landing on one side is 1/2 = 0.5 = 50%.So the result of the next flip has a chance of 50% of coming up heads.
