What term describes a species whose removal would affect many other species, both directly and indirectly
A. predator species
B. Keystone species
OC. cascading species
OD. phoresy species
Next
Answer:
Keystone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

Compare and contrast pollution caused by irrigation and by pesticides.
Pesticide pollution and irrigation pollution have different characteristics, but both have the potential to have negative effects on the ecosystem.
Here is a side-by-side comparison of the two:
Pesticide usage and irrigation both have the potential to contaminate water. Excessive irrigation can result in the contamination of nutrients in water bodies due to the leaching of pesticides and fertilisers.
Both pesticides and irrigation can have a negative impact on ecosystems. Excessive irrigation water use can harm aquatic habitats and deplete water supplies.
Pollution sources: Irrigation is a major cause of pollution due to the excessive water use and subsequent discharge of nutrients, silt, and fertilisers.
Pesticides, on the other hand, are chemical compounds created especially to manage pests and have the potential to pollute the environment directly through runoff, spray drift, or persistence in the soil.
Management and Regulation: Irrigation and pesticides are managed and regulated in different ways. Policies for managing water resources and conservation measures can be used to control irrigation practices.
Contrarily, the use of pesticides is subject to stricter laws and oversight to guarantee correct application, handling, and mitigation of side effects.
Thus, this is the comparison and difference between pollution caused by irrigation and by pesticides.

Normal blood cells slide easily through narrow blood vessels. In sickle cell disease many red blood cells change to a crescent shape like a slender moon Crescent-shaped blood cells cause blockages in blood vessels These blockages decrease the transport of oxygen People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body Some people have one sickle cell gene and one normal gene They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the method of reproduction in humans result in people getting one copy of a sickle cell gene and one copy normal gene? Describe the process
Answer:
Explanation:
The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.
The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent during copulation giving rise to an individual that is heterozygous for the trait
For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.

After removing a cutting from a parent plant, farmers usually:
Answer:
Plant the cutting in a different location
Explanation:
A cutting is a piece of a plant that is usually cut by farmers during agricultural practices. It is a means of vegetative (asexual) propagation.
The part of the plant which is cut is usually the stem or root of the parent plant. The cutting is then placed in a favorable environment which is mostly moist soil for proper growth .

What is a Schwarzchild radius and what does it have to do with a black hole
Answer:
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole
Explanation:
The Schwarzschild radius define the “size” of a black hole. Theorists believe that all the “stuff” inside a black hole collapses into a singularity, an infinitely small and infinitely dense point well inside the boundary defined by the Schwarzschild radius.

Seth will attend college in the fall and live in the dormitory, so he is required to obtain a blank against bacterial meningitis, which will stimulate his body to produce immunity to the disease. He reads that meningitis is a fast-acting and potentially fatal disease, transmitted by blank in the respiratory droplets of infected individuals. The bacteria are blank that cause disease by destroying blank and releasing blank that disrupt the body’s normal homeostasis. Bacterial infections are treated with blank , which block the growth and reproduction of bacteria.
Key answer: bacteria, vaccine, cells, pathogens, toxins, antibiotics
Answer:
vaccine
bacteria
pathogens
cells
toxins
antibiotics
Explanation:
Bacterial meningitis is a serious disease that is caused by an infection which results into Inflammation of brain and spinal cord membranes.
It is generally caused by virus but also caused by fungus and bacteria. A vaccine is required to fight against the bacterial meningitis. Symptoms include fever, stiff neck and headache. This disease is carried by the bacteria present in the throat of infectious person and can transmit through coughing, sneezing and kissing. The bacteria are the pathogens, releases a toxin which destroy cells and surface components of nervous system.
This disease is treated with intravenous antibiotics and corticosteroids (sometimes).
Hence, the correct answers for blanks are vaccine, bacteria, pathogens, cells, toxins, and antibiotics in sequential order.
