In the chesapeake bay and other bodies of water, what is a result of phytoplankton population increases?
Dead zones are created by hypoxia and the bacterial decay of dead phytoplankton.
What are the effects of excess phytoplankton population?The Chesapeake Bay, like many other bodies of water, is overrun with nutrients, which results in a type of pollution called eutrophication. Every spring, sewage treatment facilities, farms, and lawns release large amounts of nitrogen and phosphorus into the Bay. These nutrients fuel the growth of algae as the water warms up in the summer, resulting in blooms that deplete the water's oxygen content and create sizable "dead zones" where fish, crabs, and other aquatic life find it challenging to survive. During these times, some of the mud's surface layers and portions closer to the bottom may become anoxic, meaning there is no oxygen present at all.

(b) What are the differences between reproduction in Rhizopus and in maize.
The Zygomycetes fungal family, which often lives on dead and decaying plant matter, includes Rhizopus, arguably the best-known genus in the group.
Typically, maize is used to make animal feed. It undergoes extensive processing to produce a wide range of goods, including cornmeal, grits, starch, flour, tortillas, snacks, and morning cereals.
How does reproduce Rhizopus and maize?A fungus's species name is Rhizopus. By producing spores, they reproduce asexually. The hyphae that make up the fungus's body create the sporangium. A swelling structure called the sporangium is at the end of the filaments carrying the spores.Drilling for maize seed should be done evenly and into moisture. For maize to flourish, soil temperatures must be 8C in the morning for four to five days.The differences between reproduction in Rhizopus and maize:
Rhizopus reproduction:
It reproduces by vegetative, asexual, and sexual mechanisms.
Rhizopus Vegetative Reproduction
The Rhizopus thallus can occasionally shatter into a few fragments by accident or due to other causes, and under the right circumstances, each fragment will grow into a new thallus.
Rhizopus Asexual Reproduction
Both sporangiospores and chlamydospores can be used for asexual reproduction.
Maize reproduction:
Both male and female reproductive organs are present in maize plants, which reproduce through self-pollination and cross-pollination.
The female component (the ear) extends from a central stalk in most commercially viable maize genotypes, whereas the male structure (the tassel) extends from the top of the stalk.
The wind carries pollen from the tassel to other maize plants, where it fertilizes the individual kernels on the ear. Maize can have ears that are anywhere between 2.5 and 45 cm long. The size, shape, and color of the kernels vary greatly as well.

What is water potential?It is the capacity of water to move from one place to another. Work is done when a substance moves from one place to another. Simply put, water potential is the capacity of water to do work.
Water moves into and out of a cell depending on the water potential of the cell and that of the ambient solution. naturally, water will always move from the region of high to the region of low water potential in cells.

rt A When the diaphragm contracts, _______. When the diaphragm contracts, _______. it lifts the rib cage it flattens out and it rises in the thoracic cavity it flattens out it rises in the thoracic cavity
When the diaphragm contracts, it flattens out.
The diaphragm is a thin layer of skeletal muscle that is seen below the lungs. It is seen at the chest base and it helps to separate the chest from the abdomen. The contraction and relaxation of the diaphragm increase and decrease the thoracic volume which allows the air to enter and exit the lungs.
The contraction of the diaphragm increases the thoracic volume which forces the air to enter the lungs. This process is called inhalation. The diaphragm in its resting state appears dome-like and when it goes back to its resting state it pushed the carbon dioxide-rich air out. This is called exhalation.
The diaphragm is made up of fibrous tissue and skeletal muscles. It has a central tendon that anchors the diaphragm to the ribs. It also has 3 large openings they are esophageal opening, aortic opening, and caval opening. Some smaller ones are also present that allows the nerves and vessels to pass through. The actions of the diaphragm are controlled by the right phrenic nerves and left right phrenic. The inferior phrenic arteries supply blood to the diaphragm.

Cross one parent that is heterozygous for both beak color and feather color with a parent that is homozygous for both recessive traits. What are the genotypes of the parents
Heterozygous for both traits genotype = BbFf
Homozygous for both traits genotype = bfbf
What are homozygous and heterozygous traits?
The term "identical genes received during the zygote period of development" is homozygous. The parents of a person with homozygous features gave them one copy of each allele. Both dominant and recessive alleles are possible.
Children with heterozygous traits inherit a dominant gene from one parent and a recessive allele from the other parent.
Let the alleles for beak color be:
Dominant allele = B
Recessive allele = b
Let the alleles for feather color be:
Dominant allele = F
Recessive allele = f
Therefore,
Parent 1 with heterozygous traits will have genotype = BbFf
