Answer:

1,6 m / s ^ 2

Explanation:

De las leyes de Newton;

Fuerza = masa × aceleración

masa = 275 kg

Fuerza = 440 N

Aceleración = Fuerza / masa

Aceleración = 440N / 275Kg

Aceleración = 1,6 m / s ^ 2

Answer:

Basal metabolism,  Physical activity, Growth, Pregnancy and Lactation.

Explanation:

Basal metabolism,  Physical activity, Growth, Pregnancy and Lactation are the five factors that determine energy requirements in human beings​. To perform daily physical activities, we need a lot of energy which can be taken through breaking of food molecules as well as stored form of macromolecules such as fats and proteins etc. Energy is also needed for the metabolism and growth in humans beings because metabolism and growth processes needs energy.

Answer:

Food costs more because there is less cropland

Explanation:

The amount of cropland available increases  is the most likely result of converting farmland to urban development. So, the correct option is A.

Urban planning is also called city planning, town planning, regional planning or rural planning which is defined as the technical and political process focused on the development and design of land use.

This development involves the transformation of an area into an urban state in various dimensions such as physical, geographical, economic and social through population and land use change. The conversion of farmland to urban development has many effects in terms of food security, reduced agricultural productivity, and agricultural labors.

The amount of cropland available increases  is the most likely result of converting farmland to urban development.

Therefore, the correct option is A.

Answer:

Option D

amount of sunlight absorbed

Answer:

they obtain oxygen from water through gills

Explanation:

Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.

This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

Glycolysis breaks down 3-carbon molecules into 2-carbon molecules.

Answer:

Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.

Explanation:

The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.  

Answer:

it reflects green light and absorbs other colors.

Explanation:

The term pigment derives from the Latin pigmentum, which means the substance that produces color.

Pigments provide color to cells and tissues.

In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.

Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.

The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.

The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.

Answer:

B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.

Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.

Carbon is stored on our planet in the following major sinks (1) as organic molecules in living and dead organisms found in the biosphere; (2) as the gas carbon dioxide in the atmosphere; (3) as organic matter in soils etc

Answer:

Plants developed roots to absorb water from the ground

Answer:

Vascular seedless plants evolved specific structures to transport and hold fluids, reducing dependence on water sources.

Explanation:

If given the ability to hold on to water, the plant does not have to frow directly on a water source.

Answer:

Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. ... They can maintain different environments in a single cell that allows them to carry out various metabolic reactions

Answer:

Explanation: Akaryocytes, also known as akaryotes or acaryotes, are cells without a nucleus. The most common type of akaryocytes are viruses. The name is derived from the Greek prefix "a-", meaning "without" and the Greek "karyo-", meaning "nut" or "kernel". ... This cell biology article is a stub.

Answer:

There are no gram positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaeic cell walls are more similar to gram negative bacterial walls, although they do show a greater variety of cell wall types.

EXPLANATION

Bacteria can be divided into gram-positive bacteria and gram-negative bacteria because of their cell wall composition.   The cell wall of gram-positive bacteria is made up of peptidoglycan which retains crystal violet stain and appears purple in color under microscope. The cell wall of gram-negative bacteria has an outer layer of lipopolysaccharide which do not retain crystal violet color and appear pink.   The cell wall of archaea is not made up of peptidoglycan but is made up of pseudo-peptidoglycan, therefore, no gram-positive archaea species is present on the earth.

Explanation:

During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. ... Carbon dioxide is the waste product of cellular respiration that you breathe out each time you breathe. Blood picks up oxygen and releases carbon dioxide in the lungs.

Answer:

- I believe transcription.

-  Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein development.

- the end product is RNA.

Answer:

B) binding of a molecule to a binding site affects the binding properties of another site on the protein.

Explanation:

In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
