"Biological" redirects here. For other uses, see Biological (disambiguation).

Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[1][2][3][4][5]

Biology deals with the study of life and organisms.

Biologists are able to study life at multiple levels of organization.[1] From the molecular biology of a cell to the anatomy and physiology of plants and animals, and to the evolution of populations.[1][6] Thus, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they used.[7][8][9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, and perform experiments to satisfy their curiosity about the world around them.[1]

Life on Earth, which emerged before 3.7 billion years ago,[10] is immensely diverse. Biologists have sought to study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. These various living organisms contribute to the biodiversity of an ecosystem, where they play specialized roles in the exchange of energy and nutrients.

Name 2 structures present in root hair cell that are not present in a red blood cell
vekshin1

Answer:

Root hair cells are alive and therefore need energy, which is why root hair cells contain many mitochondria in them. Root hair cells don't contain chloroplasts. Chloroplasts are used by the plant to make food using light energy. Since the roots aren't exposed to any form of light, they have no need for chloroplasts.

some heterozygous alleles create variations in expression so that there is not a clear dominant or recessive allele true or fals
Simora [160]

Answer: False

 The variations in expression depends on how genes code for proteins that would specify whether it will be dominant or recessive allele.   Within a population, there may be a number of alleles for a given gene and these differences can cause variations in the protein that is produced. The change in protein expression affect traits due to the variations in protein activity or expression that produce different phenotypes.

<span>Moreover, individuals that have copies of different alleles are known as heterozygous and individuals that have two copies of the same allele are referred to a homozygous. The expression patterns observed in inheritance will depend on whether the allele is found on an autosomal chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>

Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the
AysviL [449]

Answer:

An individual can be placed or classified into a particular species depending on the concept a scientist has considered,

The three most prominent are Biological, morphological and phylogenetic species concept.

1. Biological species concept- Individuals that can interbreed naturally are placed into the same species. Therefore, Biological  species concept, not applicable for extinct species

2. Morphological - Relies on similarities in structure

This species concept places individuals having similar body structures into the same species. It can be easily applied to asexual and extinct species.

3. Phylogenetic - Based on evolutionary history

Species are classified according to a common ancestor.

4. Morphological and Phylogenetic

Accommodates asexual reproduction

Species acceptance criteria can be subjective

5. Morphological, Phylogenetic, and Biological

Used by scientists in classification

All the three concepts are used for classification.
