Soil is a mixture of weathered rock and organic material.
Answer:
C
Explanation:
The brother has different alleles for the blood type gene than his sister does. Blood type is inherited from parents like many other traits that can be displayed on a punnet square. Depending on what the parents blood type alleles were, the brother and sister could have different blood types.
A different number of chromosomes doesn't lead to different blood types, so D is wrong. And A is incorrect because the number genes also does not affect blood type. And I think the blood type genes are on the same chromosome, so B is wrong. C is correct because blood type is inherited by alleles, and different alleles can cause different traits, such as blood types.
Answer:
The correct answer is - Inhibits cell cycle progression.
Explanation:
Smoking marijuana affects the body in several ways and also causes mutation to the DNA which leads to the disruption of the cell cycle. The major effect on the cell cycle of marijuana is due to the chemical present in it known as #9
-Tetrahydrocannabinol.
THC or #9 -Tetrahydrocannabinol inhibits the cell cycle progression by arresting the cell cycle in different stages that prevent the cell to proliferate and it is proposed for the research in treating tumors.
Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles.
Answer:
carrier protein
Explanation:
To resolve this, a specialized carrier protein called the glucose transporter will transfer glucose molecules into the cell to facilitate its inward diffusion. There are many other solutes that must undergo facilitated diffusion to move into a cell, such as amino acids, or to move out of a cell, such as wastes.
