Answer: Generally, these factors are based on two things: hydrostatic pressure and osmotic pressure. Water will only flow across a membrane firstly if the membrane is permeable to water.
Explanation:
The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
Answer:
Mitosis is when a diploid cell becomes 2 haploid cells with single chromosomes
Explanation:
Any theory must contain a meaningful concept with new evolution to accept by the scientific community
Answer
Chemical elements and water are constantly recycled in the ecosystem through biogeochemical cycles. During the water cycle, water enters the atmosphere by evaporation and transpiration, and water returns to land by precipitation.
