Q

pH scale definition

A

From the range 7-14, a solution is basic. Whenever the value of pOH is greater than 7, then it is considered basic. At pH 7, the substance or solution is at neutral and means that the concentration of H+ and OH- ion is the same.From the range 1-7, a solution is acidic. So, whenever the value of a pH is less than 7, it is considered acidic.

Q

What is the definition of an element?

A

An element is a substance consisting of atoms which all have the same number of protons - i.e. the same atomic number.Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods.

Q

What is the definition of natural selection?

A

the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

Q

What is the respiratory system?

A

The respiratory system (or ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.

Q

What is photosynthesis?

A

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Q

How do sound waves and pitch relate?

A

Humans perceive pitch based on the frequency of the sound wave that is detected by the ear. High-frequency sound waves have a high pitch; low-frequency sound waves have a low pitch.

189
Q

<p>what is cellular membrane?</p>

190
Q

<p>what is nucleus?</p>

193
Q

195
Q

<p>what kind of cell are animals and plants?</p>

A

<p>eukaryote</p>

196
Q

<p>What process do animal cells go through?</p>

A

<p>cellular respiration, which is the process of taking in food in the form of carbohydrates which makes energy in the form of ATP and removing waste</p>

197
Q

<p>What is the equation for cellular respiration?</p>

A

<p>Glucose (sugar) + Oxygen ---> Carbon Dioxide + water + energy (as ATP)</p>

198
Q

<p>what process do plant cells go through?</p>

A

<p>photosynthesis which is the process of making their own food by using carbon dioxide, sunlight, and turning them into carbohydrates</p>

199
Q

<p>What is the equation for photosynthesis?</p>

A

<p>Carbon dioxide + water + sunlight -----> glucose (sugar) + oxygen</p>

200
Q

<p>what happens to the waste of animal cells?</p>

A

<p>it becomes nutrients plants use to go through photosythesis</p>

201
Q

<p>what happens to the waste of plant cells?</p>

A

<p>it becomes nutrients for animals to use to go through cellular respiration</p>

202
Q

<p>what kind of relationship do plants and animals have?</p>

A

<p>symbiotic relationship</p>

203
Q

<p>plants have:</p>

A

<p>cell wall, chloroplasts, phtosythesis</p>

204
Q

<p>animals have:</p>

A

<p>plasma membrane, no chloroplasts, cellular respiration</p>

205
Q

<p>what are the 2 types of reproduction?</p>

A

<p>sexual and asexual</p>

206
Q

<p>characteristics of sexual reproduction</p>

A

<p>2 parents, ech contribute a gamete (sex cells), male gamete: sperm, female gamete: ova (egg), occurs in both plants and animals</p>

207
Q

<p>characteristics of asexual reproduction:</p>

A

<p>- involves 1 parent</p>

208
Q

<p>what are the 4 types of asexual reproduction?</p>

A

<p>binary fission, budding, fragmentation, parthenogenesis</p>

209
Q

<p>what is binary fission?</p>

A

<p>single parent cell doubles its DNA then divides into 2 cells, usually occurs in bacteria</p>

210
Q

<p>what is budding?</p>

A

<p>small growth on the surface of parent breaks off to continue growing into adulthood, usually occurs in yeast & some animals</p>

211
Q

<p>what is fragmentation?</p>

A

<p>piece of the organism breaks off and those pieces develop into new organism</p>

212
Q

<p>what is parthenogenesis?</p>

A

<p>when an embryo develops on unfertilized cell, this occurs in invertebrates as well as some fish, amphibians, and reptiles</p>

213
Q

<p>what are the benefits of sexual reproduction over asexual?</p>

A

<p>sexual offspring's are genetically different, genetic diversity has more advantages because it allows populations to adapt and evolve</p>

214
Q

<p>what are the 4 phases of mitosis?</p>

A

<p>Interphase (not an actually phases but very important) prophase, metaphase, anaphase, telophase</p>

215
Q

<p>what is interphase?</p>

A

<p>cell prepares for division, it pumps and replicates its DNA within the nucleus & DNA is uncoiled which is call chromatin & organelles double (structures within the cell membrane)</p>

216
Q

<p>what is prophase?</p>

A

<p>DNA tightly coils into chromosomes to make splitting efficient & the nuclear membrane dissolves -the microtubes or spindle fibers attach to each chromosome</p>

217
Q

<p>what is metaphase?</p>

A

<p>chromosomes (tightly coiled DNA) move to the middle of the cell & the spindle fibers attach to each chromosome</p>
