Explanation:
The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.
What is feedback mechanism?The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.
The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.
Positive feedback loops and negative feedback loops are the two types of feedback loops.
Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.
Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.
Thus, the correct option is B.

The eyes work with the brain and other body parts through a series of steps that help you catch a ball. What step takes place right after your eyes send the image of the ball to the brain? Group of answer choices The brain realizes that a ball is coming toward you. The brain sends a message to the muscles in your arms to move. The eyes see the ball. The muscles pull on the bones in your arms as you catch the ball.
The correct answer is A. The brain realizes that a ball is coming toward you.
Explanation
The optical components of the eye are those that allow the formation of the image on the retina and are the following: the cornea, the lens, the pupil, the aqueous humor, and the vitreous humor that allow the formation of an image on the retina. After this, the image is transmitted to the brain through nerve impulses. According to the above, the step after your eyes send the image of the ball to the brain is A. The brain realizes that a ball is coming toward you.

Answer:
Reproduce prolifically.
Explanation:
Purple loosestrife, also known as Lythrum salicaria, is a tall Eurasian plant that spreads quickly. It can attack home gardens and grows mainly in wetlands and ditches. Purple loosestrife can rightly produce over 2 million seeds per plant, which can easily spread by wind and water and also remain viable in soil for several years. The insects and diseases that helps reduce the population of these plants are not found in North America

Explanation:
Hydroponic greenhouse is a type of greenhouse that would be best in Siberia where the growing season is short and we wants fresh tomatoes all year round. Tomato plants are able to grow takes less time in hydroponic greenhouse because plants grow 30% to 50% faster in hydroponics than when grown in soil. Under the right conditions, the productivity of tomato is higher three and 10 times as compared to traditional methods of tomato cultivation.

Explain how temperature and amount of precipitation can affect the type of plants and animals found in the desert biome?
Answer:
A influência da vegetação sobre o clima acontece de diferentes formas, influenciando tanto no albedo quanto na umidade e nas variações de temperatura. Isso significa dizer que alterar a cobertura vegetal de um dado local é também propiciar alterações climáticas no local da intervenção e também em outras partes do planeta. A consequência de uma maior umidade do ar é a menor amplitude térmica (a diferença entre a maior e a menor temperatura), ou seja, a ocorrência de médias de temperaturas mais constantes. Isso ocorre em razão do calor específico da água, responsável por conservar o calor por mais tempo.
Explanation:
Answer: In the desert biome the temperature's are extreme. They could get to over 100 degrees. Plants and animals adapted to their environment over man centuries. The amount of precipitation a plant or animal get can effect how they grow. Plants need lots of water so the can grow and flourish and animals need it so they can live. If the don't get enough then they could die. Th plants there need to endure long-spread drought. So they need deep roots so they can soak up lots of water. animals like the coyote go out in the night. when it's cooler. they hunt lizards.

What is the per capita growth rate of a population of frogs that has a per capita birth rate of 1 frog and a per capita death rate of 2 frogs?
a. 1
b. 2
c. -1
d. 0
Answer:
c. -1
Explanation:
When 1 frog is born, 2 frogs die, so it is +1 and -2.
Add them together to get the answer: 1 + -2 = -1
The per capita growth rate of a population of frogs that has a per capita birth rate of 1 frog and a per capita death rate of 2 frogs is -1. The correct option is C.
What is the growth rate?The growth rate is the specific rate of change of the variables of a specific place and specific time. Growth rate is calculated by collected data of a place, and it is compared to the former population.
The growth rate of frog is here given, the growth rate is also depended upon the death rate of the population, death rate is subtracted by the population
The per capita growth rate is 1
The per capita death rate is 2
When 1 frog is born, 2 frogs die, so it is +1 and -2.
Adding them together:
1 + -2 = -1
Thus, the correct option is c. -1.
