A geologist finds some tilted sedimentary rock layers.
Which conclusion can the geologist draw by looking at the rock layers?
1.Their absolute age is 600 million years.
2.They were tilted before they were deposited.
3.They were originally deposited horizontally.
4.The youngest layer was originally deposited as the bottom layer.
Answer:
Angular unconformity also causes geologic tilting. Angular unconformity occurs when parallel strata of sedimentary rocks are deposited on layers that are tilted, perhaps as a result of erosion. So the answer I think is B/2.

How does the natural process of meiosis support evolution?
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.
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.

What changes can occur in an aquatic ecosystem as a result of nutrient loading? (Site 1)
Answer/Explanation:
Essential nutrients such as nitrogen, phosphorus, at specific moderate level are needed for the overall functionality of the aquatic ecosystem. However, when excess of these elements infiltrates the aquatic ecosystem, the nutrient overload causes a surge in the growth of aquatic plant. For example, algal bloom. These increased growth of aquatic plant further takes up space and oxygen, prevents sunlight and later leads to what is known as "dead zone". It is a condition of an ecosystem having little or no biological activity. Aquatic life is impacted negatively when this occurs.
These are the changes that occurs as a result of nutrient loading.

The displacement of the object is 303.75m.
What is displacement?Distance covered by a body in a particular direction is called displacement. To calculate displacement from a velocity-time graph, we calculate the area under the curve.
The displacement is covered by drawing perpendiculars on the time axis. Let AB be the first and CD be the second perpendicular.
Extend A to CD at E.
Now, area of ABCD trapezium
= (AB + DC)/ 2 × AD

share a common genetic code?
The first life was self-replicating RNA has an accepted hypothesis about the origin of life on Earth and explains how all organisms share a common genetic code.
What is genetic code?
The genetic code is the language that our body utilizes to translate the DNA instructions from our genes into the building blocks of life. Given that mRNA is the messenger that sends information from the DNA to the location of protein synthesis, it is frequently explained using the "codons" contained in mRNA.
In the end, the genetic code serves as the foundation for everything in our cells. Our DNA serves as a storage medium for the information that is passed down from parent to kid, or what is known as our hereditary information. The RNA and proteins produced from that DNA are later employed to create cells, tissues, and organs.

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.
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.
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
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.
