Explain whether an experiment or an observational study would be more appropriate to investigate whether meditation is effective in lowering blood pressure.
Answer:
Experiment.
Explanation:
An experiment would be more appropriate method to investigate whether meditation is effective in lowering blood pressure because experiment has a control group as well as a testable group. Due to control group and testable group, we can easily find out the effect of meditation in lowering blood pressure if we apply meditation techniques to the testable group and compared it with the control group, we get results.
what is some advice you would give to someone who doesn’t know the importance of carrying capacity
Answer:
For someone who doesn't know the importance of carrying capacity, i would advice him to understand what carrying capacity mean, and then tell him that he should not overcrowd the population of animals or be part of humans overcrowding as it can destroy the ecosystem or resources.
Explanation:
This is because, carrying capacity is the population size that can conviniently live in an habitat with the available resources..
It's very important because, it will ensure that the population size that the resources can sustain can live in the environment so as to prevent degradation of the ecosystem or the environment due to increase in population size.

significance of active transport in food processing
Answer:
Why do we need active transport?
Moving Against a Gradient
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances that living cells require in the face of these passive movements. A cell may spend much of its metabolic energy supply maintaining these processes.

3. What happens during each of the four phases
of mitosis? Write one or two sentences for
each phase
Answer:
After DNA replicates and the cell is about to divide, the DNA condenses and coils into the X-shaped form of a chromosome. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase.
Mitosis is a process of division in which a parent cell is divided to form two identical daughter cells.
Mitosis completes into 4 steps:
Prophasemetaphaseanaphasetelophase.What is the process of mitosis?The process of mitosis division completes into four stages:
Prophase – The chromosome is condensed and compact. The spindle fiber forms.Metaphase – The nuclear membrane dissolve, and the spindle fiber aligns all the sister chromatids (chromosome) in one line.Anaphase – The sister chromatids separated from each other and centromere. The spindle takes each strand to the opposite pole.Telophase – the nuclear membrane appears again around each set of the chromosome. The chromosome uncoil and the cytoplasm divide into two cells, and this process is called cytokinesis.Thus, this is the process of mitosis.

Suppose DNA polymerase synthesizes DNA at a rate of 1000 bases per minute in a newly discovered bacteria and that bacteria replicates 50% of their chromosome every 40 minutes. Calculate the total number of nucleotides in the bacterial chromosome.
Answer:
320000 nucleotides
Explanation:
Given that:
The rate of synthesis by DNA polymerase = 1000 bases per minute
The time taken to replicate 50% of their chromosome = 40 min
Thus, the time taken for one complete round of replication = (40 × 2) min
= 80 min
∴
The total number of nucleotides in the newly synthesized strand = 1000 pairs/min × 80 min × 4
= 320000 nucleotides
The total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).
Bacteria are prokaryotic microorganisms whose genome consists of a single circular chromosome.In this case, it is possible to obtain the duration of DNA replication from data:
40 minutes (min) >> 50% bacterial chromosome40 x 2 = 80 minutes (min) >> 100% bacterial chromosomeThe length of the bacterial chromosome can be easily calculated:
DNA replication rate = 1000 base pairs (bp) per minuteTotal chromosome length: 80 x 1000 bp = 80000 base pairs (bp)A kilobase (kb) is equal to 1000 base pairs (bp) of DNA, thereby in this case the bacterial genome is equal to 80 kb.In conclusion, the total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).

Which is a difference between active and passive transport?
A. Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
B. Cells only carry out active transport when they need to move, while passive transport occurs constantly.
C. Active transport requires ATP, while passive transport does not.
D. Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.
The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.
Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).
Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.
Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.
Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.

The glucose transporter used by cells to obtain glucose from the media is a protein embedded in the membrane. When researchers first started to investigate the glucose transporter's structure they had trouble because it seemed to have 2 differnet shapes! Eventually they realized that the glucose transporter changes shape as it moves glucose into the cell but does not require energy to do it's work. Which of the following is the best description for the glucose transporter?
a. It's a carrier protein doing facillitated diffusion
b. It's a carrier protein doing active transport
c. It's a protein channel doing facillitated diffusion
d. It's a protein channel doing active transport
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
Explain the three main ways energy is transferred, provide examples of each
Answer:
Conduction: It is when heat energy moves from place to place.
Convection: It is when fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy.
Radiation: It is a transfer of heat by electromagnetic wave
Explanation:
Answer:
Conduction is the transfer of energy from one molecule to the next by direct contact.
Convection is the movement of heat by a fluid such as air or water.
Radiation is the transfer of heat by electromagnetic waves.
Explanation:
Convection is known as the process of transferring energy or heat through a fluid (liquids or gasses) from high temperatures to low temperatures. Convection is known as one of the three types of heat energy transfer. The other two types of heat energy transfer are conduction and radiation. Conduction is known as the transfer of heat between anatomies that are directly touching each other. while, during radiation, the energy is discharged in the shape of electromagnetic waves.
As for the molecular motion in liquids, it is the result of convective heat energy transfer. Furthermore, the movement of the molecules increases as the temperature of the molecules is increasing. The result of this is that the molecules seem to move away from each other. The motion of the molecules is what is responsible for the transfer of heat.
