Characteristics of living things show up everywhere. Here's the thing: It's not enough to exhibit one or two characteristics. In order to be considered a living thing, the thing in question must exhibit all the characteristics of living things. There are six distinct characteristics that all living things possess. Not four, not ten, six. If a particular thing shows all six of the characteristics of living things, it can be said to be a living organism. These are the six characteristics needed to be considered a living thing.

Part 1: Read each question carefully and choose the correct answer.

Vesna [10]

Answer:

1. d

Explanation:

The correct answer would be that the system of peer review is used to determine conclusively the conclusions of the paper.

The system of peer review refers to the process of evaluating a scientific report or paper by one or more independent scientists who have a similar background as the producer of the report or paper.

The reviewers evaluate the methodologies and various claims made by the original researcher and give feedback on their validity as well as make criticism of the paper in order to improve its quality before final publication. However, reviewers do not alter the claims or conclusions of papers, they can only query them.

Hence, options a, b, and c are correct as far as the peer review system is concerned.

The only incorrect option here is d.

2. There are 3 types of experiments, namely:

controlled experiment
field experiment
natural experiment

The controlled experiment involves the comparison of experimental group with control group. The two groups are subjected to the same conditions except for the variable whose effects are being researched.

The field experiment takes place outside the laboratory settings as opposed to other types of experiments. The subjects of the field experiment are studied in their natural environment outside the lab.

The natural experiment involves studying a phenomenon naturally without having control, unlike the controlled experiment. Observations are just recorded and are used to arrive at predictions or hypotheses.

Part 2:

Subject: 30 - 60 years old males

Control: Group B, the placebo group

Constant: Diet.

Independent variable: Administered drugs (choless and placebo)

Dependent variable: cholesterol level.

Part 3

Experiment 1:

a. Independent variable: types of detergent

b. dependent variable: height of foam

c. constant variables: amount of water, container type, temperature, period of agitation.

Experiment 2:

a. independent variable: amount of weight in each car

b. dependent variable: amount of gasoline left in each car

c. constant variable: car, type of gas, speed of car, distance covered by car.

Experiment 3

a. independent variable: amount of light

b. dependent variable: number of remnant bacterial cells after exposure to light

c. constant variable: initial number of bacteria, petri dish, type/amount of growth medium.

Experiment 4

a. independent variable: level of salinity

b. dependent variable: biomass of plant

c. constant variable: type of plant, period of growth, growth conditions.

What happens during cellular respiration?

mylen [45]

Answer:

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

What are some unique ways that genetics is used in the field of medicine and health

hram777 [196]

Answer:

Explanation:

Genetics is a branch of biology that deals with the study of genes, genetic variability and hereditary in different organisms. Genetics can be used in medicine and health as outlined below.

1. Use for early detection of genetic disorders I.e it is used for prenatal disorders.

2. To test for mutations(change in gene content) in DNA which causes different deadly diseases e.g breast cancer.

3.It is use to manage diseases associated with metabolism.

4.It is use for molecular diagonistics of different kind of genetics diseases e.g celiac disease, Wilson disease e.tc.
