magine that a scientist takes a group of Anolis lizards and introduces them into an enclosure at a research facility in continental South America. He notes that the lizards thrive in this new environment. The fact that Anolis lizards could survive in habitats outside of the Caribbean is a reflection of their ____ niche; their _____ niche is determined by their ability to disperse to other areas as well as predation and resource availability.

Answers

Answer: Fundamental, realized

Explanation:

The realized niche of a species is usually the result of predation, competition, and other types of interaction between species.

The size of realized niche is determined by interspecific competition .The fundamental niche is larger than the realized niche.

The fundamental niche represents all the habitats where a species could possibly live, but competition among different species usually restricts a species to a smaller area, which is the realized niche

During production of a drug, all work area surfaces must be disinfected using sterilized disinfectants. Which of the following statements about disinfectants are true? Select all that apply. View Available Hint(s)for Part A Disinfectants destroy all microbes present on a surface. Disinfection can be used to treat work surfaces as well as workers (i.e., washing hands). Disinfection can occur by physical or chemical means. Disinfectants are used to inhibit or destroy pathogens. Endospores and viruses can resist disinfectant treatment.

Answers

Answer: The correct options are

--> Disinfectants are used to inhibit or destroy pathogens,

--> Disinfection can occur by physical or chemical means,

--> Endospores and viruses can resist disinfectant treatment.

Explanation:

To prevent infectious diseases from spreading or to sterilise work area surfaces during the production of drugs, chemicals known as disinfectants as used. These are chemicals that kill or inhibit the growth of pathogens. Other chemicals such as antiseptics can also kill and prevent the growth of mainly pathogenic microorganisms. However, disinfectants are stronger chemicals than antiseptics and so are often used on non-living things and surfaces.

Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores (endospores) and viruses, so it is less effective than sterilisation.

There are generally two methods of disinfection:

--> The chemical method: A typical example of a chemical disinfectant is the carbolic acid. It is used for disinfecting lavatories and floors.

--> The physical method: here, physical agents are use to disrupt and damage the pathogenic organisms on work surfaces. Some typical example include: UV irradiation, heat, sunlight exposure, sonic or hydrodynamic pressure and radiation.

1.- Embrión se desarrolla dentro del sistema reproductor femenino.
2.- Formación de un organismo a partir de huevos

Answers

Answer:

1. Vivíparo

2. Ooviparismo

Explanation:

Viviparismo se define como el proceso de desarrollo de un animal en el cual el embrión crece dentro dentro del sistema reproductor femenino en una estructura acorde que le permite obtener alimento y oxígeno hasta su nacimiento. El viviparismo placentario es el tipo de desarrollo más extendido entre mamíferos (por ejemplo, perros, caballos, gatos, conejos, etc), a excepción de mamíferos que son ovíparos (por ejemplo, el ornitorrinco) y los mamíferos marsupiales que no poseen placenta y donde feto se desarrolla en una bolsa externa llamada marsupio (por ejemplo, los canguros). Por otra parte, el oviparismo es un mecanismo de desarrollo en el cual el embrión crece dentro de un huevo desde el momento que la hembra lo expulsa hacia el exterior. Cuando se produce este suceso, los embriones se encuentran muy poco desarrollados y por lo tanto deben cumplir su ciclo de crecimiento (hasta eclosionar del huevo) fuera del vientre materno. Algunos ejemplos de animales ovíparos incluyen anfibios, reptiles, aves, insectos, etc.

A. Each daughter cell mutates its own DNA during Reduction Division to produce more variation.
B. Each daughter cell is unique, providing natural variation.
C. Each daughter cell is identical, providing natural variation.
D. It does not support evolution.

Answers

A. Each daughter cell mutates it’s own DNA during reduction division to produce more variation

During meiosis, each daughter cell tends to undergo mutation of its own DNA and leads to more variation. The correct option is A.

What is meiosis?

Meiosis is a sort of cell division that occurs in organisms which reproduce the fusion of gametes and results in a diminution in the number of chromosomes in gametes. Body cells in humans are diploid, with two sets of chromosomes.

Meiosis is a process of cell division that produces 4 gamete cells while reducing the number of chromosomes in the parent cell by half.

This process is essential for the generation of egg and sperm cells for reproduction.

Meiosis reduces the number of chromosomes in a cell by half while also generating new allele pairings that are dispersed across daughter cells via segregation and recombination.

This genetic reshuffling, which is thought to be the basis of reproduction success, reduces genetic affiliations within and between loci.

Thus, the correct option is A.

Imagine taking a bite of a pizza. Briefly discuss the role that each part of the brain takes in this simple act. Medulla, Pons, Cerebellum, Thalamus, Hypothalamus, Amygdala, Hippocampus, Parietal Lobe, Occipital Lobe, Temporal Lobe, Frontal Lobe.

Answers

Answer:

- Medulla: transmits signals between the spinal cord and higher brain levels

- Pons: transmits impulses related to the voluntary skeletal movements from the cerebrum to the cerebellum

- Cerebellum: coordinates skeletal muscle contraction, conscious/subconscious movements, maintains muscle posture, and balance

- Thalamus: regulation of the human nervous system

- Hypothalamus: maintains the overall homeostasis of the body

- Amygdala: processes fearful and threatening stimuli  

- Hippocampus: regulates learning, memory encoding and consolidation, and spatial navigation

- Parietal Lobe: processes information from the outside world (e.g., touch, taste, temperature)

- Occipital Lobe: interprets information from the eyes

- Temporal Lobes:  process sensory information (i.e., pain and auditory stimuli)

- Frontal Lobe:  higher cognitive functions (e.g., memory, problem-solving, emotions, impulse control, etc)

Explanation:

The medulla (medulla oblongata) is the lowest portion of the brainstem, which is linked by the pons to the midbrain and continues with the spinal cord. The medulla is known to transmit signals between the spinal cord and higher brain levels, thereby controlling autonomic activities (e.g., heartbeat and respiration). The pons is a mass of transverse nerve fibers that links the medulla with the cerebellum, it transmits signals from the forebrain to the cerebellum. The pons is involved in different functions, e.g., sleep, respiration, hearing, equilibrium, taste, eye movement, swallowing, bladder regulation, facial expression, etc. The cerebellum is a small part of the brain involved in physical movements (e.g., posture, balance, coordination), which receives sensory information from sensory systems, the spinal cord, and different parts of the brain. The cerebrum is the largest part of the brain, it is involved in speech, thinking, reasoning, problem-solving, emotions, initiating/coordinating movements, regulating temperature, learning, etc. The thalamus is a mass of gray matter located in the forebrain which is involved in diverse functions (i.e., relay of sensory signals, regulation of consciousness, sleep, alertness, etc). The hypothalamus is a small, central, area of the brain that connects the nervous to the endocrine system that acts to maintain the overall homeostasis of the body. The amygdala is a structure located in each hemisphere of the brain that processes fearful and threatening stimuli. The hippocampus is a structure located in the depths of the temporal lobe that regulates learning, memory encoding and consolidation, and spatial navigation. The parietal lobe is located at the upper back area in the skull, it is involved in processing sensory information from the surrounding world (e.g., touch, taste, temperature). The occipital lobes are responsible for transmitting visual information to the temporal lobes, and they are also associated with memory skills. The frontal lobe is the most anterior part of the brain, which is involved in higher cognitive functions (e.g., social interaction, motor function, memory, emotions, impulse control, problem-solving, etc).

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?

Answers

Answer:

The bird population might have to migrate in search for food or may decline in numbers.

Explanation:

This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.
