Molecules such as glucose and amino acids can be absorbed from the digestive tract and a renal tubule by the process of facilitated diffusion, which involves a carrier protein that can transport a molecule across the cell membrane down its concentration gradient. The process involves a process of spontaneous passive transport of molecules or ions across a biological membrane via specific trans-membrane integral proteins.
Answer: Homologous chromosomes
Explanation:
Homologous chromosomes are the pair of chromosomes that are contained in diploid organisms such as humans. There are 23 pairs of homologous chromosomes, and 46 in total (44 non-sex chromosomes and 2 sex-chromosomes)
During gamete formation, the mother produces an egg cell with 23 chromosomes, and the father produces a sperm cell with 23 chromosomes. Both combines, fertilize and yield a single cell known as Zygote with 46 chromosomes (i.e 23 pairs of homologous chromosomes)
Answer:
Nitrates
Explanation:
A. Acid-- acid is right, but not the best answer.
B. Nitrates are fertilizers, which are things that would be used in all of these situations
C. Fuel-- no one is pouring gasoline on their grass to make it grow.
D. Sewage-- same as gas, but this time it is sewage.
When tectonics plates shift, they hit and form mountains and volcanos. So when there is no boundary, there is fewer mountains. Hope this helps.
Answer:
A plant which has a horizontal underground stem is a Rizome.
WHAT IS A RIZOME?
Rhizome, also called creeping rootstalk, horizontal underground plant stem capable of producing the shoot and root systems of a new plant. Rhizomes are used to store starches and proteins and enable plants to perennate (survive an annual unfavourable season) underground.
