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.

Answer:
A. longer pregnancies & periods of infant dependency
Explanation:
Primates are known to mature slowly compared to other mammals, they have a longer gestation period and longer period of infant dependency. Therefore the period between birth and adulthood is usually longer compared to other mammals, which then result to late age in their first reproduction.
For example humans have a gestation period of 365 days while baboons is 187 days compared to rabbits with a gestation period of about 33 days or mice with a gestation period of about 20 days
Of any primate, humans exhibit the longest period of infant dependency, Chimpanzee is about 5 years compared to other mammals.
A. a decrease in Oxygen
This is because trees take is Carbon Dioxide and they give off Oxygen. The more that trees are cut down the less oxygen we get.
Answer:
Characteristics of Chordata. Animals in the phylum Chordata share four key features that appear at some stage during their development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post- tail (Figure 2). In some groups, some of these are present only during embryonic development.
