which statement is true regarding the agricultural production of genetically modified organisms
Explanation:
GMO stands for genetically modified organisms. The DNA of these organisms have been genetically altered through the techniques of genetic engineering which makes the organism better than its wild variety. These genetically altered organisms are also known as transgenic as they consist.
Genetically modified organism are in widespread use nowadays. But some reports shows that they might causes some health risks and may even lead to cancer. Thus, option D is correct.
What is genetically modified organisms?Genetically modified organism or GMOs are plants or animals with recreated or specially designed genes. The genetic modification is carrying for acquiring desirable characteristics and flourishment in growth.
Genetically modified crops will grow easily with inserted properties and characteristics. However they contains certain toxins that will effects human beings.
Health issues such as reproductive disorders, hepatic and pancreatic disorders, allergic reactions and even cancer. Therefore, genetically modified organism creates problems rather than their benefits.
Hence, option D that is, GMOs may be hazardous to human health in ways that we cannot yet understand is correct.

what cells release histamine during allergic responses
Answer:
Histamine is a substance that is released by the body during an allergic reaction. Mast cells, which are a type of white blood cell, release the histamine, and this triggers a process which is most commonly referred to as the “inflammatory immune reaction”.
Explanation:
Antihistamine solutions can reduce allergies. I am allergic to mosquito bites.
The cells release histamine during allergic responses are the mast cells.
What types of cells are involved in allergy?Eosinophils, mast cells, and basophils all have been first diagnosed and defined with the aid of using Paul Ehrlich withinside the past due nineteenth century. Since then, it has end up clean that those 3 cells kinds have an awful lot extra in not unusualplace than their popularity with the aid of using the equal scientist.
Mast cells are multifunctional bone marrow-derived tissue-residing cells which might be the principal manufacturer of histamine withinside the frame. H1R are expressed in lots of cells, along with mast cells, and are concerned in Type 1 hypersensitive reaction reactions.

Name THREE broad areas in which water may be used
in society.
Answer:
Agricultural, Commercial, Public, and Domestic
The three main areas where water may be used in a society is agricultural, domestic and household activities.
What are uses of water?Our communities rely heavily on water to function. There wouldn't be any local commerce or industry without water. Public swimming pools, city parks, and firefighting all require a lot of water.
To deliver a consistent supply of water to our taps each day, a variety of pipes, canals, and pumping stations operated by our public water systems are necessary.
Every day at home, the typical American household uses more than 300 gallons of water. About 70% of this use takes place indoors.
Therefore, The three main areas where water may be used in a society is agricultural, domestic and household activities.

in a typical animal, mitosis produces _________, while meiosis produces____________.
In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.
Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.
This process occurs in sex cells such as the sperm and egg cells.
Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.
This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

2. Discuss four types of evidence that support the theory of evolution.
HELP PLZ!!!
Evidences that support the theory of evolution;
1. COMPARATIVE ANATOMY;
This is done to compare the anatomy structures of organisms to check the adaptive changes they have undergone through time. The similarities and differences of different body structures of different organisms are checked.
Through, homologous structures where structures are similar in organisms that share the same ancestor. Example, wings of bat and wings of bird.
Through, analogous structures where structures are similar in function in different organisms. Example, fore limbs of man and monkey which are used for grabbing.
2. COMPARATIVE EMBRYOLOGY;
This is done to check embryo development in different organisms throughout time and check the similarities and differences in their development. Example, embryo of man and fish both have gills at embryo stage and in fish they develop but in man they disappear before birth.
3. FOSSILS RECORDS;
The study of fossils shows the evidence of evolution as scientists study the fossils and the development of organisms present, it displays the changes that have occured throughout the years and how other organisms share ancestors and have evolved.
4. MOLECULAR BIOLOGY;
The study of the genes of organisms to check the relationship between organisms and the changes they have undergone through time. Molecular similarities show shared ancestry of organisms. Example, human and chimpanzee share a common ancestor because they both have a gene that encodes insulin hormone.

Study the pedigree chart. ( picture above)
Which of these can be determined about the trait based on this chart?
○ The trait is recessive. the parents of A were both carriers
○ The trait is recessive. The parents of A were both affected
○ The trait is dominant The parents of te were both affected.
○The trait is dominant The parts of A were both carriers
Answer: The trait is recessive. the parents of A were both carriers
Explanation: The correct answer should be the trait is recessive.
Since we can only see A mothers tree and she is not affected by the trait she is a carrier.
Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.
So answer it will be "The trait is recessive. the parents of A were both carriers"

A: earthquakes
B: faults
C: ocean formation
D: mountains
E: volcanoes
F: island chains
G: seafloor spreading
Answer:
Earthquakes, Faults, and Island chains.
Explanation:
There are three types of plate boundary such as Constructive, destructive and transform plate boundary. The primary landform in the Transform boundary are faults which is caused by the Earthquakes. Many transform boundary landforms are in the ocean floor which is responsible for the island formation. Fault is found due to the two process such as Ridge push and ridge pull. Transform boundary neither creates and nor destroys any land in the region.
