Answer:
The answer is:B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.
Explanation:
"Eutrophication" is the enrichment of surface waters with nutrients for plants, both nitrogen and phosphorus contribute to eutrophication.
A lake with total concentrations of phosphorus and chlorophyll-a of 10 and 2.5 mg / m3 respectively, can be classified into different eutrophication classes.
The symptoms and effects of eutrophication are as follows:
· Increased production and biomass of phytoplankton, associated algae and macrophytes.
· Production of toxins by certain algae.
· Deoxygenation of water, especially at the end of algal growth situations.
The answer is:B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.

phenotypes are expected in the offspring of this cross?
From a cross of homozygous dominant and homozygous recessive parent lines with heterozygous parents, a 1:1 phenotypic ratio is seen. Two types of phenotypes will form.
A dihybrid cross involves two traits. Example: an animal with both genes for height and body coloration is taken . The height is represented as T. T is for tall characters, and t is for short characters. A homozygous dominant character is represented as TT. Homozygous recessiveness is expressed by tt.
Another gene such as body coloration is taken. Black (B) is dominant over white (b). An animal with homozygous dominant is BB. An animal having homozygous recessive is bb.
A parent with homozygous dominant for tall character and homozygous recessive for body colour is represented by TTbb. An animal that is heterozygous for height and body coloration is taken as TtBb.
From the crossing, two phenotypes are derived, such as tall black and tall white. Out of all eight individuals, four are tall black and four are tall white. The phenotypic ratio is 1:1. The cross is explained below.
Hence, two types of phenotypes will be formed with a phenotypic ratio of 1:1.

the cross is AAbb*AaBb
There would be 4 different genotypes and 2 different PHENOTYPES for the offspring. (From the first gene we can get AA or Aa from the second one Bb or bb)
AAbb
Aabb have the same phenotype
AABb
AaBb have the same phenotype
B. habitat loss
C. increased temperature
D. acid rain
The process of converting carbon dioxide and water into sugar molecules, photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.
Such as sugars, and storing this chemical energy is known as photosynthesis which indicates that the products, a sugar molecule, and six oxygen molecules, are created.
Green plants and a few other species create their food through a process called photosynthesis, which involves the utilization of water, carbon dioxide, and sunshine.
When light energy is absorbed by chlorophyll (implied by the arrow) from the reactants, six carbon dioxide molecules, and six water molecules.
Plants, algae, and certain microorganisms employ the process of photosynthesis to transform light energy into chemical energy.
Therefore, the commonly used notation for photosynthesis is 6CO₂ + 6H₂O→ C₆H₁₂O₆ + 6O₂, hence option A is correct.

Answer:
The first one is the photosynthesis equation.
Explanation:
There are four phases to the cell cycle: G1, where the cell grows; S phase, where DNA is duplicated; G2, where the cell makes final preparations for cell division; and M phase, where the cell enters mitosis. Mitosis, or cell division, is only a small part of the cell cycle.
The cell cycle is the entire life cycle of a cell until it divides into two daughter cells. It consists of interphase and the mitotic phase. Mitosis, on the other hand, is a component of the cell cycle, taking up less than 10% of the cycle, and comprises the actual process of cell division into two identical cells.
The cell cycle and mitosis are two fundamental aspects of cellular reproduction. The cell cycle is the entire life of a cell from the time of its formation until its division into two daughter cells. It can be divided into two main phases: the interphase and the mitotic phase. Interphase is the phase during which the cell prepares for replication by growing and duplicating its DNA, and the mitotic phase, during which the cell actually divides.
Mitosis, however, is just one part of the cell cycle—it is the process through which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets, forming two new nuclei. The process of mitosis is divided into five distinct stages: prophase, prometaphase, metaphase, anaphase and telophase. Week division time, mitosis takes up less than 10% of the cell cycle, while interphase takes up over 90%.
