Answers

Explanation:

hope the answer was helpful

Three codons equal one amino acid

CODON:

A codon is a nucleotide sequence consisting of three bases. The genetic code is read in a group of three nucleotide bases at a time, which are called codons.

Each codon encodes an amino acid. For example, codon AUG encodes methionine amino acid.

Each codon is read during translation to form an amino acid sequence. This means that the number of codons in a mRNA (nucleic acid) sequence determines the number of amino acids in a sequence.

Therefore, three codons equal one amino acid.

Why is there Cholesterol in your cell membrane?

Answers

Answer:

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

Explanation:

Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

It helps to restrict the passage of molecules. Since it is small, it can work to fit and block off water soluble molecules from diffusing into the membrane.

B. Transpiration
C. Evaporation
D. Fixation

Answers

Hey there!

Photosynthesis is part of the carbon cycle.

Plants absorb carbon dioxide & sunlight in the middle of the photosynthesis process and create glucose (a type of sugar).

I hope this helps,

have a wonderful day. :)

Photosynthesis is part of the carbon cycle. Therefore option A is correct.

Photosynthesis is a vital process in the carbon cycle, which is the biogeochemical cycle that describes how carbon is exchanged and recycled between the atmosphere, living organisms, oceans, and the Earth's crust.

During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, such as glucose, using sunlight as an energy source.

This process removes CO2 from the atmosphere, reducing greenhouse gas levels and helping to regulate the Earth's climate.

It is an essential step in maintaining the balance of carbon in the biosphere and plays a significant role in sustaining life on our planet.

Therefore option A Photosynthesis is correct.

C. Incomplete dominance

Explanation:

Incomplete dominance is a type of non-mendelian inheritance in which one allele does not completely mask the phenotypic expression of the other allele in a gene, hence, the blending of both alleles give rise to an intermediate third phenotype.

According to this question, there are three options for fur color in mice namely: black, grey and white. This is so because the alleles for black and white coloration exhibits INCOMPLETE DOMINANCE, hence, they produce a third phenotype (grey) that is a blend of both parental phenotypes.

Discuss how the properties of water help Earth support life.

Water Property:

Importance to Life:

Polar molecule:

Hydrogen bonding:

Cohesion:

Adhesion:

Surface Tension:

Temperature Moderation:

Low density of Ice:

Universal solvent:

Answers

Answer:

One of water’s important properties is that it is composed of polar molecules. The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen. Thus, it is more likely that a shared electron would be found near the oxygen nucleus than the hydrogen nucleus. Since water is a nonlinear, or bent, molecule, the difference in electronegativities between the oxygen and hydrogen atoms generates the partial negative charge near the oxygen and partial positive charges near both hydrogens.

Explanation:

As a result of water’s polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds. Water also attracts, or is attracted to, other polar molecules and ions, including many biomolecules, such as sugars, nucleic acids, and some amino acids. A polar substance that interacts readily with or dissolves in water is referred to as hydrophilic (hydro- = “water”; -philic = “loving”). In contrast, nonpolar molecules, such as oils and fats, do not interact well with water, as shown in. These molecules separate from it rather than dissolve in it, as we see in salad dressings containing oil and vinegar (an acidic water solution). These nonpolar compounds are called hydrophobic (hydro- = “water”; -phobic = “fearing”).

The properties of water help Earth support life helps in various ways.  Most of the role of the water in supporting life is because of its molecular structure which causes its specific properties.

Water is a simple molecule made of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom.

Polar molecule: The charge difference between the positive charge on one side and the negative charge on the other side form an asymmetrical molecule called a polar molecule that interacts with different molecules. Hydrogen bonding: Due to hydrogen bonding water has various life-supporting properties by the interaction of various molecules. Cohesion: water molecules attract other water molecules in a property called cohesion that plants take up water at their roots and it affects boiling point regulates body temperature of animals. Adhesion: Attraction to other molecules called adhesion that helps in binding with different types of molecules  Surface Tension: surface tension of water is similar to the cohesion Temperature Moderation: water's heat capacity or specific heat prevent immediate temperature changes Low density of Ice: helps ice to flow on water not to immerse. Therefore life under the ice can be maintained. Universal solvent: makes water dissolve with other molecules and make a life-sustaining force that helps cells transport and use substances like oxygen or nutrients

Thus, water is essential for supporting life and survival.

7. Explain how magnetic potential energy can be transformed into kinetic energy. ​

Answers

Answer:the potential energy by the magnetic field can turn into kinetic energy once the field is moving from the S pole to the N pole when it reaches the N pole it is potential energy when it exits the S pole it is kinetic energy.

Explanation:

The magnetic potential energy can be effectively transformed into kinetic energy by that fact when it moves to the South pole of the magnet.

What is Kinetic energy?

Kinetic energy may be defined as a type of energy that is possessed due to its motion. It is characterized as the work which is required in order to accelerate a body of a given mass from rest to its stated velocity.

The potential energy in the magnet can be efficiently get stored at the north pole while when it moves to the south pole of the magnet, the energy can be transformed into kinetic energy. This type of energy is possessed by the virtue of its motion.

Therefore, the magnetic potential energy can be effectively transformed into kinetic energy by that fact when it moves to the South pole of the magnet.

What was the health of the ecosystem of Atlas National Park like before wolves were reintroduced? *WILL GIVE BRAINLIEST*

Answers

Answer:

the populations of their prey—the deer, rabbits, and so on—may increase due to a lack of at least one natural predator.

Explanation:

Wolves are causing a trophic cascade of ecological change, including helping to increase beaver populations and bring back aspen, and vegetation. Today, nearly 25 years after wolves were reintroduced into the park, the top predators have helped parts of the ecosystem bounce back. They've significantly reduced elk herds, opening the door for willow, aspen, beaver and songbird populations to recover.

The health of the ecosystem is not good due to imbalance conditions.

The health of the ecosystem of Atlas National Park is not good before the introduction of wolves because the population of herbivore such as deer increases which leads to the destruction of all vegetation present in the park as a result the park health deteriorates.

When the wolves are introduced in the ecosystem, they controls the population of herbivores i.e. deer that feeds on the grass and the recovery of vegetation that was lost due to herbivorous animals occur so we can conclude that the health of the ecosystem of Atlas National Park is not satisfactory before wolves were reintroduced in the park.
