Allen pours water into a graduated cylinder. He notices that the surface of the water is curved, as shown below.
Slav-nsk [51]

Answer:

When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).

Explanation:

A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.

<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.

Which of the following statements about chemiosmosis is NOT true?
melomori [17]

Answer:

I don't know the answer to the first one, but I can answer the second question. <em>Cellular respiration </em><u><em>has carbon dioxide and water as waste products</em></u><em>.</em>

Explanation:

<em>Cellular respiration</em> does <u>not</u> form glucose & oxygen and doesn't occur in the chloroplast, but does form <em>ATP energy</em>, <em>carbon dioxide</em>, & <em>water</em> and the process occurs in <em>mitochondria</em>. Photosynthesis on the other hand forms glucose & oxygen and does occur in the chloroplast.

A pair of mice are bred several times generating the following data table. What are the most likely genotypes of the parents?
Tamiku [17]

Answer:

This question lacks options, the options are:

A) FF and ff

B) FF and Ff

C) Ff and Ff

D) Ff and ff

The answer is D (Ff and ff for parent 1 and 2 respectively)

Explanation:

This question depicts a single gene coding for fur colour in mice. The gene controls two traits, black fur and white fur, encoded by alleles F and f respectively.

According to the question, a pair of mice has been bred several times to generate the same data of 22 black fur and 23 white fur mice. Based on this data, it shows that the phenotypic ratio of black to white mice is 1:1.

To get a 1:1 phenotypic ratio of black fur offspring to white fur offspring, the parents mice must have genotypes Ff (heterozygous) and ff (same recessive alleles).

In a cross between parents Ff × ff (see punnet square), offsprings with the following genotypes will be produced: Ff, Ff, ff and ff. Ff is black furred while ff is white furred.

Ff (2) : ff (2) is equivalent to Ff (1) : ff (1).

Hence, a data of 22 black mice and 23 white mice which represents a 1:1 ratio will only be produced by parents mice with genotypes: Ff and ff.
