Who eats whom in an ecological community is described by food webs. Food webs, which are composed of interconnected food chains, help us comprehend how changes to ecosystems—such as eliminating a top predator or introducing nutrients—affect numerous species both directly and indirectly.
The foundation of aquatic food webs is made up of phytoplankton and algae. Primary consumers like zooplankton, small fish, and crustaceans consume them. In turn, fish, small sharks, corals, and baleen whales consume the primary consumers. Large sharks, billfish, dolphins, toothed whales, and large seals are some of the top ocean predators. All aquatic life in this food chain is consumed by humans.

the lining of the abdominal cavity and some of its organs is called the select one or more: a. membrane b. thoracum c. peritoneum d. mesentery
Option C: The peritoneum is the lining of the abdominal cavity and some of its organs.
The Peritoneum is a membrane of a sheet of smooth tissue that lines the inside of the abdominopelvic cavity and surrounds the abdominal organs. It also covers many other organs inside the visceral layer. It acts as a pad and insulates the organs, helps them to hold them in place, and secretes a lubricating fluid to reduce friction when they rub against each other. The space between the layers is called the peritoneal cavity. The folds of tissue form double layers, which hang down the front of the abdomen, and mesentery in the back.

What is the direct result of this biological process?
a) duplication of genetic material
b) formation of mutations within cells
c) fertilization of an egg with a sperm
d) generating new combinations of alleles
Answer:
C
Explanation:
The direct result of this biological process is generating new combinations of alleles. The correct option is d.
What are chromosomes?Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
"Allele" is the word that we use to describe the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to lump the alleles into categories. When chromosomes cross over happens, the alleles changes and a new combination produces.
Therefore, the correct option is d. generating new combinations of alleles.

The process of meiosis occurs during the_______and results in_____.To maintain the correct number of chromosomes in offspring, male and female gametes contain chromosomes as somatic cells. During fertilization, gametes fuse to form a_____ cell called a zygote
2. Complete the statements about photosynthesis:
Glucose molecules are a product of _____ during_____ . After heterotrophs ingest food, glucose molecules are broken down during _____ in _____.
Answer:
Sex cells, haploid number of chromosomes, Diploid cell.
carbondioxide and water, photosynthesis, respiration, carbondioxide, water and energy.
Explanation:
The process of meiosis occurs during the division of sex cells and results in haploid number of chromosomes. During fertilization, gametes fuse with each other to form a diploid cell called a zygote. Glucose molecules are a product of two reactants known as carbondioxide and water during the process of photosynthesis. After heterotrophs take food, glucose molecules are broken down during respiration and as a result carbondioxide, water and energy in the form of ATP are produced.
The process of meiosis occurs during se-xual reproduction and results in haploid cells. To maintain the correct number of chromosomes in offspring, male and female gametes contain chromosomes as somatic cells. During fertilization, gametes fuse to form a diploid cell called a zygote.
Glucose molecules are a product of plants during photosynthesis. After heterotrophs ingest food, glucose molecules are broken down during glycolysis in the cytoplasm.

restricted? Are there some situations in which
such regulations would be more appropriate
than others?
Answer:
that depends the the kind of antibiotic it is. yes there some that may end up cause more problems then fixing them but there are some antibiotics that be very well within the human body. so if you ask me there should only be restraints on the ones that cause more problem. then they should find a way to better them and unrestricted them. we all known we have more than enough technology to do that. if we really wanted to we could make one antibiotic to cure everything no matter what it is.

Human brain cells do not use fermentation.explain why a lack of oxygen for even a short period of time might result in the death of brain cells
Answer:
Brain cells are very sensitive and when they do not have oxygen they slowly start dying off which leads to brain damage.
Explanation:
Glycolysis produces important electrons and ATP which allow cellular respiration and fermentation to occur.
Brain produce ATP by glycolysis is the only process to generate energy, if anaerobic condition brain cells get dead.
What is fermentation?Since oxidative phosphorylation cannot make ATP in the absence of oxygen, glycolysis takes over as the cell's main source of ATP.
Because it supplies cells for the glyceraldehyde-3-phosphate dehydrogenase reaction, which comes before the steps that produce ATP, lactic acid fermentation is significant.
The adult brain only has a finite quantity of anaerobic glycolysis energy and time to sustain ion homeostasis and other vital activities before multiple events take place that cause brain cell damage and death.
Therefore, brain cells only depend on aerobic glycolysis for energy production.
