These phenotypic differences are inherited from mother cells to daughter cells.

The process of differentiation involves the expression of particular genes for each cell type in response to cues from neighbouring cells and from the extracellular environment, and the suppression of others.

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.

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.

Explanation:

The main idea of the passage is that he's using a personal anecdote to give an example of how the suspense method works

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
