Answer:
Answer:
First let's add the missing piece of information
1. Protection
2. Electrolyte balance
3. Movement
4. Support
The answers
A. 3
B. 4
C. 1
D. 2
Explanation:
A. Muscles exert force against bones -3. Movement
Muscles puts a force on bones during contraction to cause body movement and lifting of objects.
B. The body's mass is suspended from bones and rest upon bones -4. Support
This provides support.
C. The lungs are surrounded by the ribs -1. Protection
The lungs are protected by the rib cage (12 sets of ribs) connected to the spine and around the lungs for protection.
D. Calcium is released from bones to restore the calcium levels in body fluids -2. Electrolyte balance
The bones is rich in calcium. It is deposited at high blood levels and released at low blood levels as it is controlled by PTH, vitamin D, and calcitonin.
Answer: There is a 50% chance that the offspring will inherit Huntington's disease
Explanation:
Huntington's disease is expressed by a dominant allele.
Since the father is heterozygous for Huntington's disease, his genotype would be as follows:Hh
Even though he carries a normal allele, the dominant allele is disease causing and thus masks the effects of the normal allele, therefore he expresses the disease.
The mother does not have Huntington's because she is homozygous recessive, in other words, she carries 2 copies of the normal alleles.with the genotype hh.
If you do a punnet square, and you cross the mother and father, the following genotypes can be produced:
Hh, Hh, hh, hh
Therefore, there's a 50% chance that the offspring will inherit the disease causing allele and 50% chance that the offspring will not inherit it.
Protists belong to the group eukaryotes (having their DNA enclosed
inside the nucleus). They are not plants, animals or fungi but they act like
one. They can be in general subgroups such as unicellular algae, protozoa and
molds. They thrive in environments with little sunlight. But they are not
plant-like organisms. The answer is letter B.
