Answer:
Flowers' importance in nature is everywhere—they can feed insects, birds, animals and humans; provide natural medicines for humans and some animals; and aid in a plant's reproduction by enticing outside pollinators. Without flowers, plants would merely be green, and the world would be a duller place.
Explanation:
Three main reasons in my view can be:
1) If flowers were not there, there would be no fruits either( which provides us about 90% nutrients ).
2) Flowers are also used to make medicines.
3) Flowers are food for many insects and some animals.
with the help of labelled diagrams briefly explain a sexual reproduction in organism
Answer:
Sexual reproduction is the process in which gametes from two different sex combine together to form a new individual.
The first stage of sexual reproduction is meiosis or gametogenesis. In this stage the diploid number (2n) of chromosomes reduced to a haploid number (n).In the next stage, the two gametes, both having haploid number (n) undergo fertilization and forms diploid zygote (2n) and the original number of chromosomes is restored.Then the diploid zygote undergoes mitosis and cell differentiation to form an embryo or offspring (2n).how many bones are in the adult human being
Answer:
I believe it is 206
Explanation:
Any biology labs easy to do ? At home
If you by any chance cook something with a bone in it (like a thick chicken bone). Put it in vinegar for a few days and the acetic acid will essentially remove the calcium out of the bone and make it wiggle and jiggle and not be hard like a bone anymore. The longer you leave it the more it will wiggle!

Si se aparean especies diferentes como por ejemplo el cruce entre caballos y burros; podemos afirmar que si llegan a tener descendencia esta va ser __________________________
Answer:
El híbrido va a ser esteril.
Explanation:
En la cruza entre dos especies distintas, cuando ocurre, existen distintos mecanismos de aislamiento reproductivo, que son barreras que inhiben o interrumpen el flujo génico entre especies distintas. Es decir que no habrá exito reproductivo de estas cruzas. Se trata de caracteres biológicos propios de cada especie que previenen la reproducción con otras especies.
Estos mecanismos de aislamiento reproductivo pueden ser precigóticos o postcigóticos.
1.Pre-copulatorios o pre-cigóticos:
Ecológico o por aislamiento de hábitat; Estacional o temporal; Sexual o etológico; Mecánico; Por incompatibilidad de gametas.2. Post-copulatorios o cigóticos:
Inviabilidad del híbrido; Esterilidad del híbrido; Híbrido con viabilidad o fertilidad disminuido; Interacciones citoplasmáticas.La mula es producto de la cruza entre dos especies distintas: una yegua (Equus ferus caballus) y un burro (Equus africanus asinus). Es un ejemplo de la accion de mecanismo poscigótico, en el cual se forma un híbrido viable esteril. Este ejemplar puede nacer, crecer y sobrevivir, pero que no puede producir gametas funcionales, por lo cual no puede reproducirse.

Answer:
evolution occurs through genetics.
Explanation:
Organisms will not able to evolve by not hunting of human and global warming because these are environmental factors which bring some behavior changes while evolution occurs due to mutation. When sudden change occurs in the genetics of an organism due to chemicals, evolution will occur. About one million years is needed for evolution of an organism. In those species evolution occurs in which there is high rate of competition. Evidence shows that two species are closely related to each other are their physical features, DNA composition and same needs for survival.

A long chain of carbon atoms connected to oxygen and hydrogen atoms C. A long chain of protein molecules D. Small molecules consisting of an amino group, a carboxyl group, and a side chain
Answer:
i think option d is the answer.
The small molecules consisting of an amino group, a carboxyl group, and a side chain describes the structure of an amino acid.
What are the functions of amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, from which proteins are composed.
Amino acids function as the building blocks of proteins. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues.
Amino acids connect to form peptide bonds through a reaction between the amino group and the carboxyl group. The amino functional group is therefore critical to building all the proteins that makeup life on earth.

A technologist decides to make a 1:20 dilution of cerebrospinal fluid (CSF) after briefly evaluating a portion of the sample microscopically. After making the dilution and charging the chambers, the number of cells that are observed in each of the large squares of the hemocytometer is >100. What should the technologist do to obtain the most accurate count
Answer:
The technologist needs to obtain a larger dilution.
Explanation:
A hemocytometer is a tool used in the laboratory for counting cells in suspension, it consists of a microscope slide that has a rectangular indentation that forms a chamber where the cells are stably maintained and counted.
The cerebrospinal fluid (CSF) is a liquid that is localized around the brain and spinal cord. Moreover, CSF analysis is a set of laboratory tests to measure the number of red and white blood cells.
The CSF tests are useful to detect different health problems that affect the central nervous system including, among others, infections in the brain (encephalitis, meningitis), inflammations, tumors, multiple sclerosis, etc.
In a CSF test, the number of white blood cells should be very low, and relatively high concentrations of such cells may be indicative of multiple sclerosis, encephalitis, leukemia, hemorrhage and allergy.
