An organism has the following genotype: AABb. What type of gametes can be produced, and in what proportions ?​

The inquiry posed is inaccurate. The correct question is as follows: The prosthetic group of hemoglobin and myoglobin is _______? The organic ring component of heme is _______? Under standard conditions, the central atom of heme is ________? In ________, the iron atom at the center is shifted 0.4 Å out of the plane of the porphyrin ring system. The central iron atom has _______ bonds: ________ to nitrogen atoms in the porphyrin, one to a _______ residue and one to oxygen. Hemoglobin is a crucial protein that carries oxygen throughout the body and contributes to the red color of red blood cells. Myoglobin facilitates oxygen transport in muscle tissues. The heme molecule functions as a prosthetic group for both hemoglobin and myoglobin, consisting of a porphyrin ring. The heme molecule contains an iron atom, specifically Fe2+. The deoxyhemoglobin states emerge when the central atom is displaced by 0.4 Å. The iron atom at the center can create six bonds, four to the nitrogen in the porphyrin, one to a histidine residue, and one to oxygen. Histidine serves as a blood buffer.

Respuesta:

D

Explicación:

Para que las células se dividan, deben replicar su ADNy los orgánulos, y para que las nuevas células sean del mismo tamaño que las demás, también deben crecer.

Answer:

Mitosis involves:

Resulting in two genetically identical

diploid nuclei

A diploid quantity of sister

chromatids align at the spindle

equator during metaphase

Meiosis I entails:

Resulting in two genetically diverse

haploid nuclei

Homologous chromosomes align

at the spindle equator during

metaphase

Homologous chromosomes pair

during prophase

Crossing-over takes place during

synapsis

Meiosis II involves:

Leading to four genetically diverse

haploid nuclei

A haploid amount of homologous

chromosomes align at the spindle

equator during metaphase

Explanation:

Mitosis is a cellular division process that generates two daughter cells identical to the parent cell. In this process, the chromosome count of the parent cell is preserved in the resulting daughter cells, meaning a diploid cell (2n) divides to form two diploid (2n) daughter cells. Sister chromatids (duplicated chromosomes) are involved at various stages of mitosis, i.e., during Metaphase, diploid sister chromatids align along the cell's equator, and during Anaphase, these sister chromatids are separated and moved to opposite poles.

On the contrary, meiosis is a type of cell division that produces daughter cells with half the chromosome number. Since the count is halved, meiosis occurs in two phases: Meiosis I and II.

Meiosis I yields two daughter cells genetically different from each other, with a reduced chromosome number (from diploid (2n) to haploid (n)). In Meiosis I, homologous chromosomes (similar but not identical chromosomes obtained from parents) pair to form a TETRAD during Prophase, allowing chromosomal segments to be exchanged between non-sister chromatids through CROSSING-OVER. This process generates genetic variability among daughter cells in comparison to the parent cell. Homologous chromosomes also align at the cell's equator during Metaphase and subsequently separate during Anaphase.

Meiosis II, on the other hand, divides the two daughter cells from meiosis I into four genetically distinct daughter cells. With the chromosome number previously reduced from diploid (2n) to haploid (n) in Meiosis I when homologous chromosomes split, haploid sister chromatids are then present and involved during the stages of meiosis II, where they align at the equatorial plane during Metaphase and ultimately separate in Anaphase.

Euglena presenta un color verde gracias al clorofila que se encuentra en los cloroplastos de este organismo, y la estructura corporal situada en su base se llama flagelo.

Explanation:

Las Euglenas son especies que habitan en aguas dulces y saladas, y se encuentran en gran cantidad en cuerpos de agua interiores, donde pueden proliferar y teñir la superficie del agua de zanjas y estanques de un color verde.

Este color verde que producen se debe en gran parte a la clorofila que se halla en sus cloroplastos, la cual es el pigmento responsable del color verde. Este pigmento también es el causante de la coloración en este caso.

Las Euglenas cuentan con una estructura corporal especializada, ubicada en la base de su cola, que les permite moverse.

Esta estructura especializada se denomina flagelo.

The answer is 2. It produces every wavelength found in the electromagnetic spectrum
