Answer:

Los fósiles, una prueba de la evolucion. El estudio de los fósiles nos da una idea muy directa de los cambios que sufrieron las especies al transformarse unas en otras; existen muchas series de fósiles de plantas y animales que nos permiten reconstruir cómo se fueron adaptando a las cambiantes

Explanation:

Answer:

homologous: have identical position, value, or structure

Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.

 

Explanation:

The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).

In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

Explanation:

When can exponential growth happen?

O A. When there are limited resources

O B. When the death rate is high
Han

O C. When carrying capacity is reached

O D. When there is no competition

Answers

Answer:

D. When there is no competition

Explanation:

If there is no competition in a population, exponential growth can occur.

Without competition, resources are not limited and a population can grow rapidly.

With limited resources, a high death rate, and a reached carrying capacity, population growth is strongly limited and cannot grow at an exponential rate.

So, answer choices A, B, and C are all incorrect.

The correct answer is D. When there is no competition

What goes on during interphase?

Answers

Explanation:

During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). ... Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA in preparation for mitosis, and conducts other "normal" cell functions.

Explanation:

During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells

A tube with a membrane covering the bottom is placed in a beaker. The membrane allows water to flow through but not salt or glucose. The tube contains an aqueous solution with 4% salt and 20% glucose and the beaker contains an aqueous solution with 12% salt and 6% glucose. How could you describe the solution in the beaker compared to the solution in the tube

Answers

Answer:

The solution in the tube is hypertonic to the solution in the beaker.

Explanation:

To compare the solutions, find the total amount of solutes in both the tube and beaker.

The tube has 4% salt and 20% glucose, so it has 24% solute.

The beaker has 12% salt and 6% glucose, so it has 18% solute.

Since 24 is larger than 18, this means the tube has more solute.

Since the tube has more solute and less water compared to the beaker, it is hypertonic to the beaker.

So, the answer is that the solution in the tube is hypertonic to the solution in the beaker.

Solutions are hypertonic or hypotonic to other solutions according to their solute concentration grade. In the exposed example, the beaker aqueous solution is hypotonic to the tube solution, meaning it is less concentrated.

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

Available data:

The membrane allows water to flow through but not salt or glucoseThe tube contains an aqueous solution with 4% salt and 20% glucoseThe beaker contains an aqueous solution with 12% salt and 6% glucose

We need to describe and compare solutions.

To do it, first, we will review some theoretical framework.

When talking about solutions in compartison with the cell content, we can classify them as follows,

HYPERTONIC ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself.

ISOTONIC ⇒ The solute concentration is the same inside the cell and outside.

HYPOTONIC ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.  

When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.  

Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the tube and the beaker- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.  

What we need to consider is

• When a cell with semipermeable membrane is placed in a hypotonic solution, water enters the cell.

• When a cell with semipermeable membrane is placed in an isotonic solution, there is no water movement.

• When a cell with semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.

In simple words, in the proposed experiment, glucose and salt -solutes- can not cross the membrane, but water can. The tube represents a cell. So,

The tube has 4% salt and the beaker 12 % saltThe tube has 20% glucose and the beaker 6% glucose.

To make the analysis easier, we can add the concentration percentages of glucose and salt at each side of the membrane, and then compare them.

The tube contains an aqueous solution with 24% solute (4% salt + 20% glucose)The beacker contains an aqueous solution with 18% solute (12% salt + 6% glucose)

We can see that the concentration of solute is higher in the interior of the tube than in the beaker. This difference suggests that water will move forward to the tube interior.

According to this analysis, we can say that

The tube aqueous solution is hypertonic to the beaker solution → More concentrated

The beaker aqueous solution is hypotonic to the tube solution → Less concentrated

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

why is rna a polymer and a macromolecule

Answers

Answer:

RNA is a polymer because it is made up of many monomers called nucleotides. Moreover, RNAs can form macromolecules because many RNAs are large molecules (i.e., polynucleotide chains).

Explanation:

Ribonucleic acid (RNA) can be defined as a single-stranded nucleic acid polymer of the four nucleotides. In RNA, each nucleotide is composed of a 1-ribose sugar, a 2-phosphate group and 3-one of four types of nitrogenous bases: Adenine (A), Cytosine (C), Guanine (G), and Uracil (U), which are covalently bonded to form polynucleotide chains. There are different types of RNAs such as mRNA, tRNA, rRNA, miRNA, circ-RNAs, lncRNAs, etc. Many of these RNAs form large single-stranded (ss) molecules, i.e., polynucleotide chains. For example, an mRNA sequence may have a length of 5,000 nucleotides (5 kb) or even more, and there are RNA viruses that have more than 20000 nucleotides (20 kb) in length.

Iron-55 has a half-life of 3 years. How much of a 40 gram sample will remain after 12 years? A. 0 grams B. 4 grams C. 2.5 grams D. 20 grams

Answers

Answer:

[tex]\boxed {\boxed {\sf C. \ 2.5 \ grams }}[/tex]

Explanation:

We are asked to find how much of a 40 gram sample remains after 12 years.

Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.

12 years/3 years = 4 half-lives

Every time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.

1 half- life: 40 g / 2 = 20 g 2 half-lives: 20 g / 2= 10 g 3 half-lives: 10 g / 2 = 5 g4 half-lives: 5 g / 2 = 2.5 g

There is also a formula that can be used to solve this problem.

[tex]A= A_o(\frac {1}{2})^{\frac{t}{hl}[/tex]

Where A₀ is the initial amount, t is the time, and hl is the half-life.

We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.

A₀= 40 g t= 12 hl= 3

[tex]A= 40 \ g (\frac{1}{2})^\frac{12}{3}[/tex]

[tex]A= 40 \ g (\frac{1}{2})^4[/tex]

[tex]A= 40 \ g * 0.0625[/tex]

[tex]\bold {A= 2.5 \ g}[/tex]

After 12 years, 2.5 grams of Iron-55 will remain.

QUESTION:-

Which is an environmental factor that affects skin color in humans?

O number of genes inherited

O amount of sunlight absorbed

O number of linked genes

O amount of food consumed

ANSWER:-

AMOUNT OF SUNLIGHT ABSORBED.

Number of gene for color of the skin is same in all the human beings and also it's a genetic factors is there will be any absence of gene due to its deletion AMOUNT OF SUNLIGHT it is variable in variable reasons which is a imp factor for the color in variation in earth. In regions near to the equator have high amount of the light so they have darker skin color then the people near the poles as there is less amount of light .Number of gene inherited is also same for each and every individual for single species for human which is 378 gene loci and if there is any variation in number due to any genetics disorder it would be a genetic factor again.amount of food consumed is different for different people with same color in same region as it only depends on the work which is done by the individual in the society for its existence. though it is a environmental factor bit it didn't effect color of the species.

SO ACCORDING TO ABOVE DETAILS WE CAN CONCLUDE (2) AMOUNT OF THE SUNLIGHT IS THE ENVIRONMENTAL FACTOR WHICH IS RESPONSIBLE FOR THE COLOR OF THE SKIN IN HUMANS
