The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the ef

Komok [63]

Answer:

The activity of Bromine will reduce

Explanation:

Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.

pH ranges tell whether a substance is acidic, basic or neural.

Acid range from 3.5-6

7- neutral

8 above is basic

Pigeon breeders prize certain looks of their pigeons. They know that pairing certain pigeons results in offspring that exemplify

sweet [91]

Answer:

Option B, Observation 2

Explanation:

The four main observation of Darwin’s areas follows –

Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment

Observation 2-

Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.

Observation 3 –

Offspring compete among themselves to survive.

Observation 4

The fittest among the competing species for survival will survive and pass on its traits to the next generation.

Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of parents to their offspring, observation 2 applies here

Hence, observation b is correct

B. Carbohydrates

C. Fats

D. Proteins

Now the correct answers of the match are as follows:

Jack is eating a diet that will help him build muscle, so he eats a diet high in this. D. Proteins

Explanation: Proteins help to build up the muscles. That's why people who want to do body-building, eat protein rich foods, like chicken, eggs, soy, etc.

Before a race, Ruth drinks a beverage full of this biomolecule to get energy. B. Carbohydrate

Explanation: This biomolecule provides instant energy to our body. For example, glucose is consumed before race, as dissolves quickly in our blood and provides instant energy. Glucose is an example of simplest carbohydrate.

These molecules in olive oil will help Ruth’s body store long-term energy. C. Fats

Explanation: Fats are the kind of biomolecule which is stored in our body in the adipose tissues. Also, when glucose is all used up by our body cells, the body starts to get energy from this stored fat.

Elizabeth has been advised to go for genetic screening to detect any abnormalities in her unborn child. A. Nucleic acids

Explanation: Every cell of our body has DNA, and it contains all the genetic information about the whole body. DNA is a kind of nucleic acid. If Elizabeth is going for test of the abnormality, it means she is going to test for the DNA of her child.
