Biology
1 answer:
geniusboy [140]2 years ago
5 0

Answer:

Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. ... In contrast, each egg cell, or ovum, is relatively large and non-motile.

Taxonomy- the classification of something, especially organisms.

Classify- arrange (a group of people or things) in classes or categories according to shared qualities or characteristics.

Binomial nomenclature- the scientific way to name living things with a two part generic (genus) and specific (species) name.

Kingdom- a country, state, or territory ruled by a king or queen.

Species- a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial, e.g. Homo sapiens.

Prokaryote- a microscopic single-celled organism which has neither a distinct nucleus with a membrane nor other specialized organelles, including the bacteria and cyanobacteria.

Eukaryote- an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaea.

Heterotroph- an organism deriving its nutritional requirements from complex organic substances.

Autotroph- an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

Unicellular- having or consisting of a single cell.

Multicellular- composed of several or many cells.

Blo 182 in assignments the artificial selection of which organisms was useful for darwin to come up the term natural selection?
miss Akunina [59]

When Darwin returned to England aboard the HMS Beagle after his voyage to the Galapagos Islands, he used artificial selection to help gather data to justify his theory of evolution. After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.

<h3>What, according to Darwin, is artificial selection?</h3>

Artificial selection is the discovery of desirable qualities in plants and animals by humans, as well as the procedures taken to improve and maintain such traits in future generations.

They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?
yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype  tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

During inhalation, which changes first in the throacic caviaty, the pressure or the volume? Explain.
____ [38]

Answer:

The correct answer to the question: During inhalation, which changes first in the thoracic cavity, the pressure or the volume, is, the volume.

Explanation:

The process of breathing, that is the cylces of inhalation and inspiration, are completely dependent on pressure gradients both on the atmosphere and inside the body, specifically the lungs and thoracic cavity. Before the breathing is initiated, both the atmospheric and alveolar pressures (alveoli are where the exchange of oxygen and carbon dioxide will take place), is equal. However, during the initiation of inspiration, the costal muscles and the diaphragm descend and open up the chest cavity, pulling with them the lungs. This causes an increase in volume capacity and a decrease of pressure within the alveoli. Since gases like oxygen tend to move from higher to lower pressure gradients, as the volume of the lungs increases, and pressure decreases, oxygen will flow from the atmosphere into the lungs. During expiration, as the lungs return to their normal state, volume diminishes, pressure increase, and the gases are thus expelled to normalize pressures again.
