Q

Qns about natural selection reminders

A
  • random mutation -> new alleles, more variation
  • pass on favourable allele
  • cumulative effect over generations = incr in favourable allele

Q

Why liver cells have a lot of mitochondria

A

Req large amts of energy to carry out functions like dea nation and detox.
Mitochondria req to release e from aerobic resp (LINK)

Q

Define mutation

A

A SUDDEN, RANDOM change n gene sequence/structure or chromosome number

17
Q

Mutagenic factor radiation

A

ALPHA/BETA/GAMMA radiation / UV light

18
Q

Large no of large fish good indicator why

A
  • fishing practices are well controlled
  • fish not caught faster than replace
  • healthy enviro w enough food
19
Q

Sex of foetus determined by the

A

Father

20
Q

Sex of child determined by

A

The alleles of the sperm

21
Q

Anaerobic respiration starts because of

A

Lack of oxygen

22
Q

How does oxygen move from plasma into rbcs

A

Diffusion of dissolved oxygen

23
Q

If given a transverse section of a stem the thick dark ring is

A

Phloem cells I think

24
Q

Does rbc have cytoplasm

A

YES

25
Q

Oesophagus and ileum circular and longitudinal muscles

A

Circular is INSIDE
longditudinal is OUTSIDE

If u take em and cut em into slices and lay em out straight the longer one is longditudinal

26
Q

When cold

A

Afferent arteriole constricts -> decr blood flow -> decr heat loss

27
Q

Uterine lining hormones

A

Maintain: progesterone
Repair: oestrogen

28
Q

Nucleotide structure

A

Phosphate (circle) — sugar (pentagon) — nitrogenous base (AT GC)

29
Q

Units of energy in an animal

A

Used for growth and repair = energy for consumers
Excretion = energy for decomposers

30
Q

Energy units in an animal

A

Used for growth and repair = energy for consumers
Excreted = energy for decomposers

31
Q

When asked which is active transport

A

Not only is it from low conc to high conc, its also THRU A PPM MEMBRANE. GOT IT. OKAY???

32
Q

How does a cell wall maintain cell turgor

A

Supports cell membrane (prevents pop)

Prevents cell from bursting

33
Q

Blood vessels in and out of liver

A

SI-> liver (hepatic portal)
Pancreas-> liver
Aorta -> liver

Liver -> vena cava

34
Q

ONLY layer of plant cells without chloroplasts

A

Upper epidermis

35
Q

What you WONT find in tissue fluid

A

Haemoglobin. Fibrin. Platelets.

They can’t diffuse out of blood vessels

36
Q

Effects of tar

A
  • carcinogenic
  • more alert
  • higher heart rate
37
Q

Functions of liver 5

A

Breakdown of rbc
Bile production
Storage of glycogen
Detox
Deamination

38
Q

Product of anaerobic resp IN BODY CELLS

A

Lactic acid.

NO CO2

39
Q

Detox in liver

A

Alcohol -alcohol dehydrogenase-> acetaldehyde -acetaldehyde dehydrogenase-> acetic acid
