When comparing mitochondria and chloroplasts in plant cells, which statement BEST explains a similarity in the cellular function of these organelles
A
These organelles are both important for the uptake of nutrients from the cell's exterior.
B
These organelles are both important in the regulated transport of molecules within cells.
с
These organelles are both important for the conversion of energy to a usable form for cells.
D These organelles are both important for the use of cellular genetic information to make proteins.
Answer:
The correct answer is - с. These organelles are both important for the conversion of energy to a usable form for cells.
Explanation:
Chloroplast and mitochondria are the two organelles that are essential for the biosphere specially autotrophs like plants and heterotrophs as chloroplast is the organelle that converts light energy into chemical energy by forming sugars by the process called photosynthesis by trapping the sunlight.
This chemical energy that is stored in glucose molecule moves to the mitochondria where by the procee of the cellular respiration the chemical energy converted to the ATP, the energy form that is used by the cell for the performing its function.

How are dewpoint and relative humidity related?
Answer:
Explanation:
Dew point is the temperature to which air must be cooled to become saturated with water vapor. Relative humidity is the percent of saturation at a given temperature; it depends on moisture content and temperature. Relative humidity is the amount of moisture actually in the air to the maximum amount that can be present at that temperature. The dew point is the temperature at which a given sample of air will have a relative humidity of 100 percent; hence, the saturation temperature.

What is the phenotype(s) you can expect from crossing a pure round parent and a
pure wrinkled parent?
R=round
r=wrinkled
Answer:
Round
Explanation:
Round is the dominant phenotype and wrinkled is the recessive one. When crossing, the offspring will have one allele from each parent, i.e. Rr, wrinkled phenotype will hence be masked by the dominant round one.

Which description is correct for both oogenesis and spermatogenesis?
The cells have 46 chromosomes until meiosis II is completed.
After meiosis I, the cells have 23 chromosomes.
Part of meiosis I is completed before birth.
The entire process takes about 70 days.
Answer:
After Meiosis I, the cells have 23 chromosomes
Explanation:
It is B
In meiosis there is a reductive phase (meiosis I) and the not reductive phase (meiosis II). Option B). After meiosis I, the cells have 23 chromosomes.
What is meiosis?Meiosis is a process by which, from a diploid germ cell (2n), four haploid cells (n) -the gametes, sperm and egg cells- are produced. This is the gametogenesis process.
Each daughter cell has half of the chromosomes of the original one.
There are two phases in meiosis:
the first one in which occurs a chromosome's reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.So, if the germ cell has 46 chromosomes, after meiosis I each new cell will have 23 chromosomes, because meiosis I is the reductive phase.
Option B is correct.
