In the question “How does pineapple consumption affect the number of digestive bacteria?”, pineapple consumption is

A) the control group B) independent Variable
C) dependent variable D) experimental group

Answers

Answer:

For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is  the independent variable (option B).

Explanation:

The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.

The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.

According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the independent variable is the consumption of pineapple, which can be controlled and modified, while the characteristic that is under the influence of this variable is the amount of bacteria, so that the latter is the dependent variable.

The other options do not apply because:

The experimental (D) and control (A) groups refer to the population in which the study is conducted. The dependent variable (C), in this case, is the amount of digestive bacteria.

Biological Oceanography

Answers

Answer: Oceanography is the study of all aspects of the ocean. Oceanography covers a wide range of topics, from marine life and ecosystems to currents and waves, the movement of sediments, and seafloor geology Geological oceanography is the study of Earth beneath the oceans.

Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.

Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.

Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

How do convection currents cause the motion of tectonic plates??

Answers

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Answer:

These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.

How do you know if something is alive? Describe some of the characteristics of living things.

Answers

Answer:

We can determine if something is a living thing by seeing if they show some of the living characteristics. These characteristics include:

Reproduction - to make more of the same organism

Sensitivity - the ability to detect and react to stimuli

Nutrition - eat and digest food.

Movement - the ability to change its position or location

Respire - to breathe / gas exchange

Excretion - get rid of toxic / materials in excess

All living things show the characteristics above.  

For example, we can be sure that robots are not living things because they cannot excrete, respire, or reproduce even if they can move and sense stimuli from outside. We can also be sure that plants are living because they show all characteristics, even for movement, we don't obviously see that, but for example, they may grow towards a light source.

Answer:

To be alive organisms have to include all of the following:

- Made up of a cell or cells

- Has DNA

- Can reproduce

- Responds to the environment

- Grows and develops

- Exchanges energy

- Evolves

Explanation:

Prokaryotic and Eukaryotic cells are both alive because they contain all of the seven necessary characteristics listed above. Viruses are not alive because they do not contain all of the seven characteristics listed above.

Except for a pairing of sex chromosomes, homologous
chromosomes_______.

a. carry the same genes
b. are the same shape
c. are the same length
d. all of the above​

Answers

Answer:

Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.

Explanation:

The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.

Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.

The homologous chromosomes are characterized by having the same shape and size, and contain the same genes, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.

Answers

Answer:

It occurs because phylogenetic analyses based on the 16S rRNA gene sequences may have insufficient resolution for distinguishing between closely related species

Another genomic method for streptococcal identification is whole-genome analysis (WGS)

Explanation:

The phylogenetic analysis of the highly conserved 16S rRNA gene sequences has recently been used to distinguish between prokaryotic species. However, this gene sometimes may show low resolution to distinguish between closely related species, and it has been suggested potential horizontal transference of rRNA genes. Moreover, multi-locus sequence analysis (MLSA) has also been used to identify species. MLSA analysis consists of analyzing simultaneously different genes and this technique has shown to have a high capacity for establishing relationships between species within a genus or genera within a family. Finally, whole-genome analysis (WGS) is the most powerful tool for distinguishing between closely species. WGS is a technique that provides a very high resolution which is based on the analysis of large-scale genome sequencing data generated by next sequencing generation (NGS) technologies.

Some scientists today believe that adaptations are more caused or provoked by the fact of competition.

What is meant by Adaptation?

Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.

Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.

Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.
