1. Agriculture has to do with farming, cultivating the soil and growing crops, as well as rearing animals to provide food, wool, and other products.
Aquaculture, or aquafarming, has to do with farming of fish, <span>crustaceans, molluscs, aquatic plants, algae, and other aquatic organisms.
2. Recreation has to do with spending leisure time, be it in zoos, aquariums, etc.
3. Biological control has to do with </span><span> controlling pests such as insects, mites, weeds and plant diseases using other organisms, such as parasitoids and pathogens.
4. Genetic conservation </span>applies genetic methods to the conservation and restoration of biodiversity.
Answer: a. Genetic recombination (crossing over)
b. Can also be explained in terms of crossing over
c. Non disjunction of homologous chromosomes in meiosis 1
Explanation:
The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.
C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.
The answer is C. It eliminates the toxic chemical problem. Hope this helps!
Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal
According to the table above, we can calculate required value:
29x4 + 6x4 + 1x9= 149 kcal/g
<span>Hemoglobin
is the part of the red blood cell that carries oxygen, and so important for
thriving. In the case of Brian, having 10.4 g/dL hemoglobin is very low. Normal
values for hemoglobin in males range from 13.5 to 17.5 g/dL. The patient has
very serious anema and note he is just 15 months old, and so needs immediate
doctor’s attention. The doctor is likely to order a blood transfusion to
elevate hemoglobin levels and stabilize the patient before ordering tests to
determine cause of anemia.</span>
