Answer:
1. Median cubital vein A superficial vein, most commonly used for venipuncture, it lies over the cubital fossa and serves as an anastomosis between the cephalic and basilic veins. 2. Cephalic vein Shown in both forearm and arm, it can be followed proximally where it empties into the axillary vein.
Explanation:
The equation to calculate the surface area is 4πr²
The equation to calculate volume is 4/3πr³
<u>Explanation:</u>
The shape of the cell is in the form of a sphere.
The surface area of the cell can be calculated by the formula =
The volume can be calculated by the formula =
Given,
The surface area of the cell is 24μm²
4πr² = 24μm²
Radius, r can be calculated from the above equation.
The volume of the cell is 8μm³
4/3πr³ = 8μm³
We can calculate radius, r from the above equation.
Therefore, the equation to calculate the surface area is 4πr²
The equation to calculate volume is 4/3πr³
Answer: pachytene stage of prophase I
Explanation:
The processes of crossing over is called synapsis and it occurs at the pachytene stage of prophase I of meiosis.
Answer:
- Periods of light-time
- Temperature
- Substrate/Soil type
Explanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
He must record and describe characteristics of that beetle
He then can compare this beetle with others to make sure it is actually a new species
