According to the graph, which region is expected to reach a population of 50 million people in the year 2040?​

Answer:

The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Explanation:

The diagrammatic illustration in this question is showing a food web made up of a variety of species feeding on one another. As shown in the food web, sea otters are one of the top predators that can eat a wide variety of organisms.

Sea urchins feed directly on kelp, however, the population of sea urchins can be controlled by sea otters which feed on sea urchins. Hence, if population of sea otters declined, more sea urchins will be available to feed on the kelp population, hence, will DECREASE.

Answer:The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

Because the otter population decreases the urchin population increases and therefore the demand for kelp increases and the kelp population will decrease as the population of urchins increases and it feeds on the kelp and due to the reduction in otters there is nothing controlling the urchin population

Answer:

A. keeping the strands separated during replication

Explanation:

Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.

After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.

La respuesta correcta es: E) naranja.

Explicación:

La vitamina C está presente en los cítricos, como la naranja, el limón y el pomelo. La naranja es una fruta muy rica en vitamina C, de hecho, basta con una al día para cumplir con los requerimientos diarios de esta importantísima vitamina.

Si bien el consumo de vitamina C no cura enfermedades, se probó que tiene un papel fundamental a la hora de reforzar nuestro sistema inmunitario, que es aquel que nos protege de los diferentes microorganismos que nos pueden enfermar.

Además de su rol importante en fortalecer nuestras defensas inmunitarias, el consumo diario de cítricos contribuye a prevenir el cáncer de colon y a regenerar los cartílagos.

Complete question:

A gene has a base sequence of GTC. Due to a mutation, the base sequence changes to GTG. Answer the following questions:

a) What are the bases of mRNA coded for by this section of DNA, before the mutation? (1 point)

b) What are the bases of mRNA coded for by this section of DNA, after the mutation? (1 point)

c) What amino acid is coded for by this sequence before the mutation? (1 point)

d) What amino acid is coded for by this sequence after the mutation? (1 point)

e) Is this is a silent mutation or a missense mutation? Explain. (1 point)

Answer:

a) mRNA before mutation ⇒ CAG

b) mRNA after mutation ⇒ CAC

c) amino acid before mutation ⇒ Glu, Glutamine

d) amino acid after mutation ⇒ His, Histidine

e) missense mutation

Explanation:

Theoretical frame

Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.

The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.

The template strand is the mRNA complement.

The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.

The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.

Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells

• The end codons are UAA, UAG, UGA.

When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.

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

In the exposed example,

Before mutation

After mutation

This is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.

Heart and lungs are the  two organs that are made up of all four tissues.     secretion, movement, strength, excretion and communication are the main functions of tissues.

Tissues are the same type of group of cells which have the same structure and functions together in a unit. Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue bone, blood, and lymph tissues.

All body surfaces are covered in epithelial tissues, which also line bodily cavities and hollow organs and make up the majority of glandular tissue. Connective tissues are presents in the blood cells in the human body. Loose connective tissue, adipose tissue, dense fibrous connective tissue, elastic connective tissue, cartilage, osseous tissue, and blood are further more tissues in the body.

Thus, Heart and lungs are the  two organs that are made up of all four tissues.

The correct order is,

I. Replicate the new organism.

II. Isolate the genes from the specialist cell.

III. Select the desired trait.

IV. Insert the genes into the target organism.

Genetic engineering (also named genetic modification) exists as a system that operates laboratory-based technologies to change the DNA makeup of an organism. This may influence changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a unique element of DNA.

Genetic engineers change, splice, eliminate, and rearrange genes to change an organism or classes of organisms. Genetic engineering, also called genetic modification or genetic manipulation exists in the modification and manipulation of an organism's genes operating technology.

Genetic engineering stands performed in three fundamental steps. These exist,

(1) The isolation of DNA components from a donor organism.

(2) The insertion of an isolated donor DNA fragment into a vector genome.

(3) The effect of a recombinant vector in a suitable host.

Hence, The accurate order is,

I. Replicate the new organism.

II. Isolate the genes from the specialist cell.

III. Select the desired trait.

IV. Insert the genes into the target organism.

Thus, Option C is correct.

Answer:

Proto-oncogenes may have mutated to become oncogenes in these cells

Explanation:

Cancer cells are characterized by key properties such as an abnormally rapid rate and poor differentiation. Proto-oncogenes are genes that lead normal cells to become cancer cells when they are mutated. Many proto-oncogenes are involved in the control and progression of the cell cycle, and apoptosis (programmed cell death) pathway. Some examples of protooncogenes include 1-the Ras gene, which is required for differentiation, growth, and cell survival (mutations of this gene have been reported in pancreatic cancer, lung cancer, colon cancer and thyroid cancer), 2-the Myc gene (mutated in Burkitt's lymphoma), 3- the Her2 receptor (a receptor kinase associated with breast cancer), etc.
