What ph must organisms maintain

Answers

Answer 1

Answer:

Explanation:pH (7)

The degree of acidity or alkalinity (basic) is important in organisms. The body must constantly maintain a near neutral pH (7) in the blood and body tissues. To do this, the body produces buffers that can neutralize acids.

Answer 2

Answer:

Final answer:

Organisms must maintain a specific pH level according to their biological requirements and environment. The majority of human body cells operate within a pH range of 7.2 to 7.6. Depending on their tolerances, microorganisms like neutrophiles, acidophiles, and alkaliphiles can thrive in varying pH levels.

Explanation:

In biological terms, the pH level is an important parameter that organisms need to maintain for survival and optimal functioning. Each type of organism has a different optimal pH range, often within a narrow window, depending on its biological requirements and environment.

Most cells in our bodies, for instance, operate within a pH scale ranging from 7.2 to 7.6. A deviation from this range could adversely affect the functioning of cells and proteins, potentially inducing coma or causing death.

Many microorganisms fall into categories like neutrophiles, acidophiles, or alkaliphiles, based on their optimal pH conditions. Neutrophiles, such as most bacteria, grow best at neutral pH close to 7.0. Acidophiles, on the other hand, grow best at a pH near 3.0, while alkaliphiles have an optimal pH range of 8 to 10.5.

These optimal pH values, minimum and maximum growth pH, cover a wide range, playing a significant role for microorganisms' survival and in food preservation. For example, the optimal growth pH of Salmonella spp. is between 7.0-7.5, but it can tolerate a minimum growth pH of around 4.2.

Extreme acidophiles and alkaliphiles can survive in astonishingly harsh conditions, with some acidophiles living at pH values near zero and alkaliphiles at pH levels around 13. However, conditions that are too acidic or alkaline could break down critical biological molecules like proteins and DNA, therefore posing substantial challenges for organisms' survival.

Answers

Answer: 7.436 s

Explanation:

This situation is related to vertical motion, specifically free fall and can be modelled by the following equation:

$y=y_(o)+V_(o) t+(gt^(2))/(2)$

Where:

$y= 0m$ is the final height of the object (when it makes splash)

$y_(o)=271 m$ is the initial height of the object

$V_(o)=0 m/s$ is the initial velocity of the object (it was dropped)

$g=-9.8m/s^(2)$ is the acceleration due gravity (directed downwards)

$t$ is the time since the objecct is dropped until it makes splash

$0=y_(o)+0+(gt^(2))/(2)$

Clearing $t$ :

$t=\sqrt{(-2y_(o))/(g)}$

$t=\sqrt{(-2(271 m))/(-9.8m/s^(2))}$

Finally:

$t=7.436 s$

The round pea seed trait is dominant over the wrinkled pea seed trait. If the phenotype of the pea seed is wrinkled, which combination of genes must have it? A.)Two round genes
B.)One wrinkled gene only
C.)Once round gene only
D.)Two wrinkled genes

Answers

D. It must have two wrinkled genes.
Whenever one or more of the parents' genes are dominant, the resulting daughter gene will be dominant.
Thus, in order to produce a recessive gene, BOTH parent genes must be recessive as well. Because wrinkled genes are recessive, you're going to need both wrinkled genes.
