Large volcanic eruptions send dust and ash into the stratosphere after these eruptions global air temperature are often
dybincka [34]
The global air temperature increases after the volcanic eruptions. It has also been observed that this increase in air temperature causes lowered winter seasons, acid rain, haze, dust, and ash. This causes problems in breathing and other disorders in humans as well as animals.

For most women, the American Academy of Pediatrics recommends exclusive breast-feeding for the first 6 months of the baby’s life
Naily [24]

Answer:

3- Breast-feeding can reduce an infant’s risk of infection, allergies, and certain chronic diseases.

.4- All mothers should consume 500 kcal extra daily while breast-feeding until weaning of the infant.

5- Women with AIDS or active tuberculosis should feed formula rather than breast-feed.

Explanation:

Breastfeeding is also a great benefit to the environment and society, that is, it does not require the use of energy for manufacturing or create waste or air pollution. Also, there is no risk of contamination and it is always at the right temperature and ready to feed. Given the importance of breastfeeding for the health of mothers and babies, Centers for Disease Control and prevention supports breastfeeding through hospital initiatives, work-site accommodation, continuity of care and community support initiatives. Colostrum is the earliest breast-milk produced, beginning in mid-pregnancy (12-18 weeks) and is continually produced for the first few days after baby's birth, it provides all the nutrients and fluid that your newborn needs in the early days, as well as many substances to protect your baby against infections.  Mothers with untreated and active tuberculosis infections are not advised to breastfeed. They may breastfeed after their infection is cured or brought under control so that it does not spread to the infant.

6) If a mutation happens in a cancer-causing gene to change the subsequent protein's function,
Aneli [31]

Explanation:

B) False

Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer

Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.

Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

One strand in a segment of a gene has the base sequence TGCTTA. What would be the complementary sequence of nucleotides found on
yarga [219]

The complementary sequence of nucleotides found on the other strand of DNA is <u>ACGAAT</u> when one strand in a segment of a gene has the base sequence TGCTTA.

<u>Explanation:</u>

Deoxyribonucleic acid is the one which carries the genetic information from the parent to the offspring.  During DNA replication one strand of DNA replicates to produce another strand.        

The DNA molecule have a anti-parallel structure and the two strands run in opposite direction. If in one strand in a segment of a gene has the base sequence TGCTTA the complementary sequence of nucleotides found on the other strand of DNA will be ACGAAT.
