In an experiment to investigate a factor affecting photosynthesis, a leaf of a potted plant which had been kept in the dark over

night was covered with aluminum foil as shown in the diagram below 1. Aluminium foil The set up was kept in sunlight for three hours after which a food test was carried out on the leaf. (a) Which factor was being investigated in the experiment? b) What food test was carried out? (i) State the results of the food test (ii) Account for the results in c (i) above​

Answer:

Photosynthetic activity.

Explanation:

The photosynthetic activity of the plant was being investigated in the experiment and no photosynthesis will occur because the aluminium foil reflect 95% of sunlight. Starch test is the food test that was carried out in the experiment. Starch from plants is broken down into its constituent sugar molecules by the plant body in order to provide energy to the tissues so if there is no photosynthesis occurs, the plant body uses starch so decrease occur in the concentration of the starch molecules when the starch food test will occur.

Which of the following statements are true about the homologous chromosomes of a pair?
Black_prince [1.1K]

The statement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.

<h3>What are homologous chromosomes?</h3>

Homologous chromosomes are set of chromosomes that possess similar but non-identical genes.

Homologous chromosomes are from each parent of an organism i.e. male and female parent.

The homologous chromosomes is responsible for the diploid state of an organism, however, it becomes separated during the anaphase 1 stage of meiosis.

Therefore, the satement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.

The inability of organisms to evolve anything that could be an advantage reflects _____.
sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.
