The question is incomplete as it lacks the multiple options. The multiple options are as follows:
a. Across the three domains, all organisms depend solely on the process of anaerobic respiration for ATP production
.
b. Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life
.
c. The existence of glycolysis as an energy-releasing process in all organisms suggests that convergent evolution occurred
.
d. All organisms carry out glycolysis in mitochondria.
Answer:
Option (b).
Explanation:
The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more closely related with each other than the prokarya.
The glycolysis is the process of breakdown of glucose molecule to generate ATP. The glycolysis is the most common process of the generation of the ATP are present in almost all the organisms whether the organisms is ancestral or modern.
Thus, the correct answer is option (b).
Answer:
B) Calculated by multiplying the rate of respiration times TV
Explanation:
Minute Ventilation is the amount of air inhaled or exhaled by a person and is measured by multiplying the tidal volume ( TV by the respiratory rate.
The phenotype is the type of trait that can be physically observed in an individual. Examples include hair colour, eye colour or height.
Answer:
What is the effect of power/magnification on the frequency and size of organelles under a microscope?
Explanation:
Organelles within the cell are responsible for carrying out various functions. Some cells are more specialized than others, and may have particular organelles at a higher frequency, or showing a variation in size; sub-cellular structures become more visible at higher magnifications under the microscope.
Hypotheses:
- organelle A's frequency decreases while B's frequency increases at higher magnifications
- organelle A's size increases while B's size decreases at higher magnifications
<em />
<em>Dependent variables: size and frequency cell organelles</em>
<em>Independent variable: power/magnification at low (x4), medium(x10) and high (x40)</em>
<em>Controlled variables: Type of organelles, microscope used, cell examined, </em>
Method:
1. Examine the organelles A and B in a cell mounted on a slide; use the fine adjustment to focus on the cell.
- Frequency: What is the average number of organelle A versus B, seen at low (x4), medium (x10) and high (x40) magnifications?
- Size: Measure the average diameter of organelle A versus B using an ocular micrometer at low, medium and high magnification.
2. Record and tabulate observations.
Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.
