Clarification:

Las algas azul-verdosas impactan el agua dulce y están directamente relacionadas con el escurrimiento agrícola y urbano.

Las fuertes lluvias de la primavera pasada probablemente causaron que el Lago Okeechobee liberara agua con algas azul-verdosas hacia ríos y canales. La espesa capa verde se deslizó sobre embarcaderos, represas y ríos, fluyendo a través de afluentes hacia el océano.

Las algas azul-verdosas (cianobacterias) son un tipo de microorganismos procariontes y autótrofos que cuentan con pigmentos fotosintéticos (clorofila y ficocianina), por lo que su ADN muestra que son bacterias.

Bacterias es la respuesta correcta.

I think the right choice is c since he realizes that certain characteristics were not being inherited.

Saturated thickness refers to the volume of water held in an aquifer that is defined by hydrogeological characteristics. The aquifer's rock contains pores filled with water, which adds to the total water volume in the aquifer. The saturated thickness decreased from 32.77m in 1975 to 22.48m in 1990, reflecting a reduction of 10.29m. Similarly, between 1995 and 2010, the thickness diminished from 25.08m to 12.27m, a decrease of 12.81m. Although the population did not change significantly from 1975 to 1990, the notable drop in saturated thickness from 1995 to 2010 could be attributed to water conservation efforts adopted by the community or natural factors such as sufficient rainfall revitalizing the aquifer and contributions from nearby water bodies like rivers, lakes, and ponds. Conservation measures include wastewater recycling and reducing water loss.

Sperm Cell: Anticipated chromosome count is 22.

The sperm cell, measuring around 5 micrometers in diameter, is significantly smaller than the ovum and has a flagellum that is 60 micrometers long for movement. To enhance mobility and reach the egg swiftly, it reduces cytoplasm and packs its DNA tightly. The head features an acrosome packed with enzymes to aid in penetrating the egg's membrane.

As a haploid cell, it carries half the genetic material of the organism, which is lost during meiosis in the spermatogenesis occurring in the testes' seminiferous tubules.

Egg Cell: Expected to have 22 chromosomes.

The egg is the female-produced gamete in animals.

Like all gametes, the egg is haploid, thus containing half the chromosomal count of the future embryo, resulting in 22 chromosomes rather than 44. This egg will eventually combine with a sperm to create an embryo with 44 chromosomes.

Daughter Cell from Mitosis: Predicted number of chromosomes is 44.

Mitosis produces daughter cells identical to the parent cell during asexual reproduction, maintaining chromosome number without splitting it in half.

Mitosis is a type of asexual cell division, which replicates a mother cell into two genetically identical daughter cells.

Daughter Cell from Meiosis II: Expected chromosome count is 22.

Meiosis is a specialized cell division that transforms a diploid cell containing 2n chromosomes (here, 2n=44) into four haploid daughter cells with n chromosomes (n=22). This reproductive process occurs in the gonads to form gametes.
