Answer:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression.
Explanation:
Mutations can result in structural alterations in a gene's translation, as well as a decrease or complete loss of the gene's function.
Because a change in the DNA sequence affects all copies of the encoded protein, mutations may be extremely detrimental to a cell or organism.
Genes have a crucial part in an organism's development and function. Mutations can result in structural changes in the decoding of a gene, as well as a decrease or complete loss of its activity.

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 might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

Given the following phylogenetic tree, which evolutionary event occurred most recently?
A.) development of different forms of symmetry.
B.) development of tissues.
C.) each of these traits evolved at the same time.
D.) protostome and deuterostome development.
Answer:
Option-D
Explanation:
A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.
The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.
The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.
Thus, Option-D is the correct answer.

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.

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.

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.
Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.
