Explanation:
Hope it helps you dear :)
Good afternoon !
Answer:
Blood pressure is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in the large arteries.
Range:-
What is high blood pressure (hypertension)?
Blood Pressure Levels
Normal systolic: less than 120 mm Hg diastolic: less than 80 mm Hg.
At Risk (prehypertension) systolic: 120–139 mm Hg diastolic: 80–89 mm Hg.
High Blood Pressure (hypertension) systolic: 140 mm Hg or higher diastolic: 90 mm Hg or higher.
Units:-
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value.

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.

The F2 generations of dihybrid crosses of Labrador retrievers are expected to produce the recessive epistatic ratio of 9 black: 3 chocolate: 4 yellow dogs. A random sample of 80 dogs was taken from F2 crosses. What is the expected number of yellow labs in the sample and what number of degrees of freedom is needed for a chi-square test of recessive epistasis
Answer:
The answer is "2 and 15"
Explanation:
sample of the chocolate labs expected number =chocolate labs fraction [tex]\times[/tex] sample size
[tex]= (\frac{3}{16}) \times 80\\\\ = 15\\\\[/tex]
The dof for recessive epistasis is = n-1, where
n =phenotypes

The wetland plant purple loosestrife was imported to North America from Europe. Since its introduction, the loosestrife has spread, which has resulted in a dramatic decline in the biological diversity of native wetland plants. A likely reason for the spread of the purple loosestrife is that it can:_______.
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

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.

A wealthy homeowner in Siberia, where the growing season is short, wants fresh tomatoes all year round.
Quonset hut greenhouse
hydroponic greenhouse
plastic sheeting greenhouse
polycarbonate greenhouse
Answer:
hydroponic greenhouse.

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.

E)
Answer: A, E
Explanation: I took the USA Test Prep and the person above me who commented said so.
An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.
Therefore, A bird builds a nest in a tree and A remora attaching itself to a shark obtaining transportation, shelter, and food scraps from the shark.
