amino acid can be split into two groups. Name and Descibe the two groups

Answers

the 2 groups are essential acids and non essential acids. basically essential amino acids have to be made from what somebody eats (your diet). non essential amino acids are made in the body.

Amino acids can be divided into two groups, and these groups are essential and non-essential amino acids.

What are amino acids?

Amino acids are micro molecules that are made up of amine and carboxylic groups. A side R group chain is also present. It is the basic unit of protein. Many amino acids join together to form protein. There is a total of 20 amino acids.

There are two types of amino acids full stop non-essential amino acids are those assets that a living body can produce, so they cannot be taken from outside food. Essential amino acids cannot be produced by the body, so they are taken in the form of food.

Therefore, essential amino acids and non-essential amino acids are the two categories into which amino acids can be categorized.

8. All of the following are true of surface currents except (1 point)
Othey are influenced by wind.
Othey can exist in large lakes.
Othey are found in the top 1,300 feet of the ocean.
Othey have the same movement as thermohaline currents.

Answers

Water current involves surface or deep water circulation. Surface currents are influenced by winds and occur in the top 1313 feet of depth. Statement 4 is false. They have the same movement as thermohaline currents.

-----------------------------------------------

Many different factors can produce water currents in lakes and oceans. Some of these factors are

winds, temperature, salinity, earthquakes, and storms.

When talking about water circulation, there are two main types of movements,

Surface circulation, which occurs from 0 to 400 meters deep (up to 1313 feet aproximatelly)

Deep circulation, which occurs at depths that super 400 meters.  

Surface circulation is closely related to horizontal water movements, while deep circulation is related to vertical ones.

Horizontal water movements

They are produced by the action of different winds on the surface.

Superficial winds, influenced by the Coriolis effects, are responsible for most of the marine currents.

Trade winds push the water surface forward western direction in the equator, while western winds produce currents that move water to the east at higher latitudes.

By the Coriolis effect, water masses are deviated to the west or the east, depending on the hemisphere, resulting in large clockwise circular turns in the Northern Hemisphere and the opposite direction in the Southern Hemisphere.

Warmer currents travel from the tropics, along the continental margins, carrying warm water to higher latitudes, and as they do so, these water masses get cooler, producing cold currents.

Vertical movements

They can be related to density, salinity, and temperature.

Variation of these factors causes thermohaline currents, which move water vertically, transporting cold water with nutrients from the bottom to the surface.

According to this resumed framework,

Surface currentshorizontal movement ⇒ up to 400 m depth ≅ 1313 feet

Deep currentsvertical movement ⇒ more than 400 m depth.

OPTIONS

they are influenced by wind ⇒ TRUE they can exist in large lakes ⇒ TRUE  they are found in the top 1,300 feet of the ocean ⇒ TRUE they have the same movement as thermohaline currents ⇒ FALSE

(Please help!) A scientist is studying the population of Cape Fox over four generations to determine if the population is in Hardy-Weinberg Equilibrium.

No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.

Yes, the population is in Hardy-Weinberg Equilibrium because the fourth generation reverts back to the initial population levels.

No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of dominant and recessive alleles are not equal.

Yes, the population is in Hardy-Weinberg Equilibrium because the recessive allele is always greater than the dominant allele.

Answers

Answer:

Explanation:

1 There are no mutations in the DNA of the population.

2 The recessive phenotype in this population may serve as an adaptation in this environment.

3 No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.

4 The brown color is an adaptation that is being selected by the environment.

5 The number of individuals displaying each phenotype in both the current generation and the offspring.

No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.

What is Hardy-weinberg Equation?

The hardy-Weinberg equation is used to calculate the genetic variation in a population, which is in equilibrium.

The equation is p2 + 2pq + q2 = 1.

The given data has changed in the frequency of allele, so there is no equilibrium.

But, Hardy-Weinberg Equation tells the genetic variation in equilibrium.

Thus, the correct option is A, No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.

Explain why inmates who have been in the dark cell for quite long usually have problems with their eyes and usually squint when in bright light?​

Answers

Answer:

No one can see in total darkness. Fortunately, there’s almost always some light available. Even if it’s only dim starlight, that’s enough for your eyes to detect. What’s truly amazing is how little light is required for you to see.

Human eyes have two main features that help us see better in low light: the pupil’s ability to change size, and the eye’s two types of light-sensing cells.

Opening up to let in more light

Your pupils are the black areas at the front of your eyes that let light enter. They look black because the light that reaches them is absorbed inside the eyeball. It’s then converted by your brain into your perceptions of the world.

You’ve probably noticed that pupils can change size in response to light. Outside on a bright sunny day, your pupils become very small. This lets less light into the eye since there’s plenty available

Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.

What are nonmetals?

A nonmetal is an element that lacks the characteristics of a metal. It is characterized by what it is not rather than by what it is. It doesn't have a metallic appearance, can't be formed into a wire, bent, or pounded into shape, has a low melting or boiling temperature, and isn't good at conducting heat or electricity.

On the periodic table, nonmetals make up a small portion and are mostly found on their right side. The one exception is hydrogen, which appears in the upper left corner of the periodic table and behaves as a nonmetal at ambient temperature and pressure. Hydrogen is projected to behave like an alkali metal under high pressure.

Therefore, Oxygen, nitrogen, and sulfur belong to nonmetals. Nonmetals do not have any lusture, they are poor conductors of electricity.

The cell cycle in the correct chronological order is the cell during interphase (image C), Prophase (image B), metaphase (image A), and Anaphase (image D) (Option C).

The cell cycle can be divided into an interphase and a mitotic (M) phase, in which the cell divides.

The interphase is the phase where the cell replicates its genetic material (DNA) and grows to prepare for its division.

The interphase divides into a Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.

The M phase can, in turn, be divided into these sequential steps:

Compare between energy yield in aerobic and anaerobic respiration. Support your answer with reference

Answers

Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.

Aerobic respiration has more energy yield than anaerobic respiration.

Cellular respiration refers to the process that has to do with breaking down food molecules like glucose which is then converted into ATP.

The cellular respiration in the presence of oxygen is referred to as aerobic respiration. On the other hand, cellular respiration in the absence of oxygen is referred to as anaerobic respiration.

It should be noted that aerobic respiration is more energy-efficient than anaerobic respiration. While aerobic processes produce about 38 ATP per glucose, anaerobic processes produce about 2 ATP per glucose.
