Give a reason why lack of roughage in diet often lead to constipation?
Answer:
Roughages increase fecal volume and promote peristalsis
Explanation:
Constipation refers to the condition in which bowel evacuations occur infrequently, leading to health problems. Some of the most common causes of constipation include 1-insufficient intake of dietary fibers or roughages, 2-poor hydration, 3-lack of physical exercise, 4-abuse of laxatives, etc. Dietary fibers are divided into two classes based on their water solubility: soluble and insoluble. These fibers represent the part of plant foods that the body can't digest, which absorbs and retains water (soluble fibers) as foods pass through the bowel and create bulk (insoluble fibers), thereby leading to regular bowel habits.
Explain how 2 polynucleotides can twist helically around each other to form a double helix of DNA?
Explanation:
The antiparallel arrangement of the two strands is what causes the twist. Because the strands run in opposite directions, they pull the sides of the molecule in opposite directions, causing the whole thing to twist around itself. Most naturally occurring DNA spirals clockwise.Place the steps shown below in the correct order.

1. Mention FIVE adaptations of aquatic organisms to their habitat. B. Write out the causative organisms fro the following infections (1) cholera (ii) malaria (iii) yellow fever C. Highlight THREE characteristics of mammals.
Aquatic animals have various structural modifications in their body to adapt to the aquatic habitats. Some of the adaptations of aquatic animals are:
Their body is streamlined and hence, they can swim easily.
They have gills as the respiratory organs.
They have fins as the locomotory organs, Various types of fins are present in fishes such as dorsal fins, pectoral fins, caudal fins etc.
The body is covered by appendages known as scales. They are meant for protection.
Some fishes have modified swim bladder with the help of which they can constantly float at a certain depth of water.

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

different seeds need different cultivation. justify in 200 words.
for 18 points
Answer:
Cultivation is the process of growing crops. we need different seeds to cultivate different types of food. Similarly, different seeds need different cultivation. For eg: we grow potatoes in well-drained loam soil. But we grow rice in muddy soil. Every seed has a different way to produce food. They need different temperate or climates, different types of soil, to grow them. They have their own time or season to grow and produce food. If we try to grow plants or vegetables in the wrong season or the wrong process, then we can't get a good result. For eg: If we try to grow rice in drained soil then it will not give us a good result or if we try to grow potatoes in muddy soil we cant get our good result.
So, we can say that different seeds need different cultivation.

Which of the following statements is TRUE?
A.Introns are the parts of mRNA that are translated into protein.
B.Introns do not have any specific function,
C.Human genes have fewer introns than genes of other organisms.
D.Introns are not excised during post transcriptional modification
Answer:
A. introns are the parts of mRNA that are translated into protein.
Explanation:
i hope it helps you
The DNA stands for deoxyribose nucleic acid, it has all the information required for the proper functioning of the human body.
The correct answer is B
The process of the formation of protein from the mRNA is called translation. it requires:-
RibosometRNAmRNAThe mRNA has the introns and the exons in it. Exons are the coding part of the DNA while the introns are the non-coding part and it does not have any specific functions.
Hence, the correct option is B that is Introns do not have any specific function.

A small size is advantageous for marine organisms because it ________. increases the surface area to volume ratio that in turn reduces frictional resistance to sinking increases the ability to absorb nutrients increases the ability of wastes to diffuse out of the organism All of the above
Answer:
increases the ability of wastes to diffuse out of the organism
Explanation:
A small size of an organism is advantageous for marine organisms because it increases the ability of wastes to diffuse out of the body of organism. Small size of an organism produces less amount of waste material and these organism does not need a very special and complex excretory system so simple diffusion of waste material occurs from the body in order to clean the body.
