The human body uses a number of processes to repair damage to blood vessels. After vasodilatation and prior to coagulation, a platelet plug forms: platelets adhere to exposed collagen and degranulate releasing ADP and thromboxane. These two chemicals in turn help attract more platelets to the area of damage.

Doug plants a few peas. After two days, he sees the shoot and the root forming. He observes that the shoot grows upward, toward the light. The root grows downward, into the soil. Why do these embryonic organs grow in a specific direction?A. The shoot is positively phototropic and positively gravitropic; the root is positively phototropic and positively gravitropic.

B. The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.

C. The shoot is positively gravitropic and negatively phototropic; the root is positively phototropic and negatively gravitropic.

Answers

The answer is B. The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.

Phototropism is reaction of a plant to a light stimulus. Growth of the plant or its part grow towards the light stimulus is called positive phototropism. Growth of the plant or its part away from the light stimulus is called negative phototropism.
Gravitropism is reaction of a plant to gravity. Growth of the plant or its part in the same direction as gravity is called positive gravitropism. Growth of the plant or its part grow in the opposite direction of gravity is called negative gravitropism.

The shoot is positively phototropic (grows toward the light) and negatively gravitropic (grows upward, in opposite direction of gravity).
The root is negatively phototropic (grows into the soil, away from the light) and positively gravitropic (grows downward, in the same direction as gravity).

How are DNA and chromosomes related to each other

Answers

DNA contains the instructions, genes, to make proteins that tell what genetic traits the person will have. The DNA along with the proteins make up the chromosomes. The chromosomes are then passed on to the offspring, and with the DNA inside the chromosomes and translation of the genes, its traits are decided.

What does the data in the graph predict?A) muscles should shiver with greater force as the body becomes colder

B) muscles should shiver with less force as the body becomes colder

C) the greater the size of a muscle, the more heat it produces

D) the smaller the size of a muscle, the more heat it produces

Answers

Answer:

Explanation:

Final answer:

Muscles are predicted to shiver with greater force as the body becomes colder, as a response initiated by the brain's heat-gain center to generate heat and maintain body temperature.

Explanation:

Based on the data provided regarding shivering as a mechanism of thermoregulation, the best prediction is that muscles will shiver with greater force as the body becomes colder. This is because as the temperature drops, the brain's heat-gain center is activated, leading to an increase in random signals to skeletal muscles causing them to contract. Shivering involves these muscle contractions that generate heat to raise the body temperature and prevent the body from losing too much heat.

Which of the following is a way that minerals are used?a. industry.
b. construction.
c. technology.
d. all of the above.

Answers

d. all of the above.

When at first thought, it would seem that it is erosion. Erosion not only eliminates the soil minerals, it also washes everything else and that includes the soil. In a different manner, Leaching can happen when certain minute particles of the minerals are melted and mixes with water. All that is left in the soil will be the bigger particles that are not soluble by water. In this manner, only a soil that cannot properly nourish remains as it is stripped off of minerals.

Answer:

it would be D. All the above hope this helps :)
