Answer: 1.chromosomes, 2. Histones, 3. prokaryotes have one chromosome, 4. A sugar phosphate backbone with nitogen bases in the middle. 5. Chromatin
Explanation: Chromatin
ANSWER:
I think it's the second one.
EXPLANATION:
in primary succession newly exposed or newly formed rock is colonized by living things for the first time. in secondary succession an area that was previously occupied by living things is disturbed, then recolonizeed following the disturbance.
I think the correct answer from the choices listed above is option B. Keratin is the protein in mammals which shows only a primary and secondary structure. Keratin is a fibrous protein forming the structural constituent of hair, feathers, hoofs, claws and many others.
Answer:
The acceleration of object is 2 m.s⁻².
Explanation:
Given data:
Force on object = 80N
Mass of object = 40 kg
Acceleration = ?
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Now we will put the values in formula.
a = 80 N/40 kg
a = 2 m.s⁻² (N = Kgm.s⁻² )
Dogs, cats and humans each contain approximately 2.5–3 billion base pairs in their DNA, comprising about 20,000–25,000 individual genes.
So we have the same DNA components
Hope this helps! Please correct me if I'm wrong :)
