The precursor of a mitochondrial matrix protein is found in a mutation in the tom22 signal receptor.
Tom22 and Tom20 function as N-terminal matrix targeting sequences' outer mitochondrial membrane receptor proteins. The buildup of mitochondrial matrix-targeted proteins in the cytosol due to a malfunctioning Tom22 receptor protein may be followed by cytosolic turnover of these proteins.
The N-terminal sequence, which directs the protein to mitochondria and is proteolytically processed upon import3, is produced in approximately 70% of mitochondrial precursor proteins3. To get to the matrix, they must pass via the TIM23 and TOM complexes on the inner and outer membranes, respectively.

<h3><u>Answer;</u></h3>
Within an ovule contained within an ovary of a flower
<h3><u>Explanation;</u></h3>
- Angiosperms are the flowering plants. Megasporangia also called female sporangia produce megasporocytes that yield megaspores.
- The megaspores develop in the megasporangium and develop into the female gametophyte generation.
- The ovule appears to be a megasporangium with integuments surrounding it. Ovules are initially composed of diploid maternal tissue, which includes a megasporocyte. Megaspores remain inside the ovule and divide by mitosis to produce the haploid female gametophyte.
]To calculate the amount of heat entering or leaving a system, the equation

T
is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.

Answer:
Proteins are molecules made of amino acids. They are coded for by our genes and form the basis of living tissues. ... For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell
