Answer the questions or write definitions of the first 20
S_A_V [24]

Answer:

1. Hypothesis:

a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation

2.Ocean systems:

The ocean is a global, interconnected system that has regions, or basins. Water and ocean life move between these basins and up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.

3.Proteins:

a class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.

4.Saturated fat molecules:

Saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)

5.Enzymes:

a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

6.Prokaryote:

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

7.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.

8.Hemoglobin:

a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a haem group.

9.Active Transport:

the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

10.Phospholipids:

a lipid containing a phosphate group in its molecule, e.g. phosphatidylcholine.

11.Facilitated diffusion:

Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
sergij07 [2.7K]

Answer:

Height is affected by multiple pairs of genes on different chromosomes.

Explanation:

The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.

Which characteristics are always present in all living organisms?
Snezhnost [94]

Q1. Heredity, cell and metabolism are the characteristic feature that are always present in living organisms

Q2. We shouldn't wrap the dissected body into the original wrapper and give instructor to dispose it off.

<h3><u>Explanation:</u></h3>

Q1. A living organism has several characteristic factors like it has cells, the cell performs metabolic activities and the organism maintains a heredity along its progenies. The living organisms must have cells which leads them to enclose their cellular components inside it. It also must have a metabolic activity to metabolize nutrition into required energy. It also do have a heredity to continue the race it belongs to.

Q2. In the dissection class, after the experiment with dissected body is over, the dissected body needs to be wrapped in fresh polythene or other bags that should be pasted with biohazard stickers and should be eliminated into specific containers that contains other biohazard wastes. The instruments must be washed thoroughly with some antiseptic and soap. The hand gloves should also be dumped within the biohazard containers wrapped in proper bags.
