A new type of fish has been discovered. It has vibration receptors on its snout and virtually nonexistent eyes. Based on these characteristics, in which part of the ocean is this fish most likely found?
If a fish has vibration receptors on its snout and virtually nonexistent eyes, these characteristics are found in the fish which leaves at the bottom of the ocean.
What is the use of receptors on fish?It is found under the skin, the lateral line made of sensory receptors known as neuromasts. While the cilia in the neuromasts vibrate, the fish can sense.
The lateral line may likewise feel and observe water pressure (depth), currents, objects, prey, and predator movements, this senses increase the chance for the survival of the fish.
Food and lure that is living and moving would be simple for fish to detect as it has a smell, sound and vibration.
Therefore, with vibration receptors, at the bottom of the ocean, this kind of fish generally found.

are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes
Answer:
The answer is B) alleles
Explanation:
Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
What do you mean by traits?Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.
Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.

Found: A Plant-Eating Spider. Spiders are meat-eaters. Until recently, scientists thought that was true for the roughly 40,000 spider species in the world. Now, researchers have discovered a spider that eats mostly plants. Bagheera kiplingi, a jumping spider, lives in Central America and Mexico. It nests in the leaves of acacia tree. Scientists have long known that ants live in these trees. The ants eat the tree’s little yellow vegetables. But scientists had no idea that the spiders eat the vegetables too. Is competition likely to occur between the Bagheera kiplingi and ants living in acacia trees? Support your answer. *
Answer:
Yes, competition is likely to occur
Explanation:
Competition is an ecological interaction between organisms of the same or different species, resulting in the detriment of one of the organisms. Competition is generally caused when organisms in an ecosystem occupies the same niche i.e. they rely on the same ecological resource, which could be food, mate, space etc.
The case described in this question involving a Bagheera kiplingi (jumping spider) and acacia ants will likely result in competition because they both occupy the same habitat and feed on the same food (vegetable plant). The two organisms will have to compete for this limited resource, hence, it is regarded as an INTERSPECIFIC COMPETITION because it involves two different organisms.

Which best describes this excerpt?
Read the excerpt from "A Simple Way to Create Suspense".
For instance, heading toward a movie review program,
remember we asked: Who was the studio's first choice for
the Harry Callahan role in "Dirty Harry"?
We knew most viewers would be intrigued. (What, Clint
Eastwood wasn't the first choice?) But—and this was the
lesson—the success of the tactic didn't depend on intrigue.
Even viewers with no interest at all stuck around to find out.
Humans are hard-wired. They need to know. Even viewers
who knew the answer for sure stuck around, in order to be
gratified. The gap was bridged, and the danger averted. (It
was Frank Sinatra. You waited, right?)

Describe the various defense mechanisms your body has to fight pathogens, nonspecific and specific. How does not washing your hands properly affect these mechanisms?
DO NOT COPY AND PASTE I WILL CHECK AND YOUR ANSWER WILL BE DELETED :)
The human body has several defense systems to deal with both generalized and specific infections. Specific defenses are targeted responses that identify and eradicate particular diseases, while nonspecific defenses are general processes that protect the body against a variety of pathogens.
What are Specific and Non-specific defenses?Physical barriers such as skin and mucous membranes, which prevent infection from entering the body, are examples of nonspecific defenses. Additional general protections include:
1. Inflammation:
A local response to injury or infection, known as inflammation, involves the mobilization of immune cells to the site of injury or infection to get rid of pathogens and encourage tissue healing.
2. Fever
Fever is an increase in body temperature that can aid in the fight against infection by slowing the growth of certain bacteria and increasing immune cell activity.
3. Phagocytosis
Pathogens are engulfed and destroyed by immune cells through a process called phagocytosis.
Specific pathogen exposure leads to specific immune responses known as specific defenses. These defenses require immune cells to recognize pathogens and mount a focused attack to destroy them. Special defenses include:
1. Production of Antibodies: Specialized immune cells make antibodies that can recognize and combat particular infections.
2. T cell activation is the process through which specialized immune cells known as T cells activate and kill cells that are infected with particular diseases.
3. Immune memory is the ability of the immune system to remember and respond more successfully to particular infections it has previously encountered.
When you don't wash your hands enough, you introduce viruses into your body and weaken both non-specific and specific defense mechanisms. For example, if you touch your face after touching a contaminated surface, you may introduce pathogens through your mouth, nose, or eyes, bypassing physical defenses against infection. By making the body's defenses less efficient and increasing the risk of infection, it can make it easier for microorganisms to cause disease.
Therefore, the human body has several defense systems to deal with both generalized and specific infections.

What would happen if a light source was placed below a plant?
• the plant would respond negative to gravity
• the plant would exhibit negative phototropism
• the plant would respond positively to gravity
A plant would respond positively to gravity if a light source was placed below a plant.
TROPISM:
Tropism is the movement of a plant or part of a plant in response to stimulus (light, heat, water). A plant's response to light is called phototropism while plants response to gravity is called geotropism. Ideally, a plant's shoot is positively phototropic while a plant's root is positively geotropic. Hence, if a light source is placed under a plant, the plant would respond positively to gravity.Learn more at: https://brainly.com/question/10942902?referrer=searchResults

Examine the diagram of the carbon cycle shown above. Through which of the following processes is carbon removed from the atmosphere?
Answer: photosynthesis
Carbon dioxide is naturally removed from the atmosphere by photosynthesis, and trees are particularly skilled at storing the carbon that is removed from the atmosphere by photosynthesis.
What processes is carbon removed from the atmosphere?Respiration and photosynthesis are polar opposites of one another. Through photosynthesis, CO2 is taken from the atmosphere and exchanged for O2. During respiration, O2 is taken from the surrounding air and replaced with CO2. However, none of these processes are in balance.
Plants use photosynthesis to transfer atmospheric carbon into the biosphere and transport it up the food chain. They make sugar molecules by chemically combining water's hydrogen and oxygen with carbon dioxide using energy from the sun.
Therefore, Plants open small pores on the surfaces of their leaves during photosynthesis in order to absorb carbon dioxide from the atmosphere and create their own sustenance.
