Eukaryotic cells have membrane-bound organelles which carry out cell functions, a Nucleus which contain DNA from the cells and a cytoplasm which is similar to a jelly like fluid interior of the cell. It also has a cell membrane which is basically an outer boundary for the cell.

Answer:

1. Cell membrane: Acts as a gate, only letting things that are supposed to enter and exit do so.

2. Nucleus: The central part of a cell that controls everything. Also contains DNA

3. Cytoplasm: Keeps all the organelles in place

What part of a plant cell responds to turgor pressure? *

IgorC [24]

Answer:

Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.

How much will atmospheric carbon change in 10 year?

viktelen [127]

Answer:

The annual average CO2 concentration for 2021 could be around 416.3ppm, according to Meteorological Office estimates. An annual rise of about 2.5 ppm is possible, which can potentially make 2021 the first year with the annual average CO2 at 50 per cent above pre-industrial levels, the estimates noted

In horses, black coat (b) is dominant over brown coat (b), and being a trotter (t) is dominant over being a pacer (t). a black h

Tomtit [17]

In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents.
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t

The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt

The black horse that is a pacer that can produce this offspring will be:
Bbtt

Therefore, the brown horse's genotype must be:
bbTt

The offspring will receive b from both parents and t from both parents.

Boats are able to stay afloat because of the force caused by...

Ugo [173]

Answer:

d) buoyancy

Explanation:

Buoyancy can be defined as an upward force which is created by the water displaced by an object.

According to Archimede's principle, it is directly proportional to the amount (weight) of water that is being displaced by an object.

Thus, the greater the amount of water an object displaces; the greater is the force of buoyancy pushing the object up.

The buoyancy of an object is given by the formula;

$Fb = pgV$

$But, \; V = Ah$

$Hence, \; Fb = pgAh$

Where;

Fb = buoyant force of a liquid acting on an object.

g = acceleration due to gravity.

p = density of the liquid.

v = volume of the liquid displaced.

h = height of liquid (water) displaced by an object.

A = surface area of the floating object.

The unit of measurement for buoyancy is Newton (N).

Additionally, the density of a fluid is directly proportional to the buoyant force acting on it i.e as the density of a liquid decreases, buoyancy decreases and vice-versa.

Boats are able to stay afloat because of the force caused by buoyancy. This simply means that, a boat is able to float because the volume of water it displaces weigh more than its own weight. Thus, if a boat or any physical object weighs more than the volume of water it displaces, it would sink; otherwise, it floats.
