The answer is C.
this is because not preparing for your experiment can result in problems or harm to the scientist. this includes a physical injury such as a burn, for example. if you prepare properly, there should not be any consequences to your lab experiment.

Answer:

C. A physical injury due to an accident or misuse of lab equipment

Explanation:

if you don't get prepared for an experiment you will be at risk of not being safe when, for example acid starts bubbling and it goes on your bare skin where if you wore a lab coat it would have hit the lab coat instead if you.

Hope it helps!

If someone who is homozygous for an autosomal recessive disorder mates with a person who does
slamgirl [31]

They have a zero percent chance of developing the disease

All the offspring will be carriers of the mutated gene but none of them will show any phenotype associated with the recessive allele. This is because they all will have the dominant allele that will mask the effects of the recessive allele of the gene.

Explanation:

Autosomal means that the allele is not on the X or Y sex chromosomes hence it is not a sex-linked gene. Male and female offspring have equal chances of acquiring the allele of the genes.  

Let us assume that the dominant allele is coded by B while that of the recessive is coded by b. The <em>attached</em> Punnet square will show the Mendelian  inheritance based on the information from the question.

Therefore, all the offspring will be carriers of the mutated gene but none of them will show any characteristics of the disorder (phenotype) associated with the recessive allele. This is because they will all have the dominant allele that will mask the effects of the recessive allele of the gene.

garik1379 [7]

The question is incomplete as it does not have the options which are:

  • Adjusts the positions of the head, the neck, and the trunk
  • Perform respiratory movements
  • Stabilize or position parts of the appendicular skeleton
  • All of the above

Answer:

All of the above

Explanation:

The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).

There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.

The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.

Thus, all of the above is correct.

Tomtit [17]

Answer:

Differences between aerobic and anaerobic respiration is whether or not oxygen is present. . During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are create, aerobic os used when heart rate and breathing rate rise, anaerobic is used during the first 1-2 mins of exercise, occurs in the cytoplasm of cells, while aerobic occurs in the mitochondria of the cells,  glycolysis occurs in both,  both are respiration, and both create ATP
