Answer;
B. Jumping rope
Explanation;
Jumping rope is not an anaerobic exercise but an aerobic exercise.
Anaerobic exercise is a form of high intensity exercise that increase the oxygen debt. However since the muscles require oxygen to maintain prolonged exertion, anaerobic exercises can only last for short periods of time.
Examples of anaerobic activity sprinting, high-intensity interval training, power lifting and most athletic sports.
1. Organism
2. Population
3. Community
4. Ecosystem
5. Biome
6. Biosphere
The question is incomplete. The complete question is:
Achondroplasia is a common cause of dwarfism in humans. All individuals with achondroplasia are thought to be heterozygous at the locus that controls this trait. When two individuals with achondroplasia have children, the offspring occur in a ratio of 2 achondroplasia:1 wild type. What is the most likely explanation for these observations
A. The allele that causes achondroplasia is a late-onset lethal allele.
B. The allele that causes achondroplasia is a recessive lethal allele.
C. The allele that causes achondroplasia is a dominant lethal allele.
D. Achondroplasia is incompletely dominant to the normal condition.
E. Achondroplasia is codominant to the normal condition.
Answer:
B. The allele that causes achondroplasia is a recessive lethal allele.
Explanation:
According to the given information, achondroplasia is a genetic disorder and the individuals with the disorder are heterozygous. The individuals with homozygous recessive genotype do not survive as the allele for the disorder is lethal in the homozygous condition. Let's assume that the allele "a" causes achondroplasia while the allele "A" imparts normal height to the individuals. Two heterozygous parents each with genotype "Aa" would produce a progeny in the following ratio=
Aa x Aa= 1 AA (normal height): 2 Aa (achondroplasia): 1 aa (do not survive).
A force can give energy to an causing the object to start moving, stop moving, or change its motion. forces occur in pairs and can be either balanced or unbalanced. balanced forces do not change in motion. they are equal in size and opposite in direction.
The first thing you need to know is wheather the cell is prokaryotic or eukaryotic. If it does not have nucleus it might be any prokaryotic cell except mycoplasma bacteria. If it is with nucleus, then it might be algae, plants and fungi. The difference between algae, plants and fungi cell wall is in their structure. Plant cell walls containlignin, suberin or cutin, algae possess cell walls made of glycoproteins and polysaccharides and fungi possess cell walls made of the N-acetylglucosamine polymer chitin.
