Answer:
True
Explanation:
Similarly, in humans (2n=46), there are 46 chromosomes present during metaphase, but 92 chromatids. It is only when sister chromatids separate – a step signaling that anaphase has begun – that each chromatid is considered a separate, individual chromosome.
The statement that the human cell will have 46 chromosomes during the metaphase of meiosis II is false.
Chromosomes refer to the thread-like structures that can be found in the nucleus of organisms. The chromosome consists of protein as well as a single molecule of DNA.
It should be noted that the human cell has 23 chromosomes during the metaphase of meiosis II. It doesn't have 46 chromosomes during the metaphase of meiosis II.
Therefore, the statement is false.

What evidence supports the LAW OF CONSERVATION OF ENERGY?
1. Mechanical energy is converted to chemical energy during photosynthesis
2. Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis
3. Oxygen is made from the breakdown of carbon dioxide during photosynthesis
4. The sun gives off light energy that is absorbed by plants
The evidence that supports the law of conservation of energy is as follows: mechanical energy is converted to chemical energy during photosynthesis.
LAW OF CONSERVATION OF ENERGY:The law of conservation of energy states that energy can neither be created nor destroyed but is changed from one form to another. This means that energy involved in chemical reactions and natural phenomena is recycled by transformation and doesn't get destroyed. A typical example that obeys this law is photosynthesis, which converts mechanical energy in sugar molecules to chemical energy in ATP.Learn more about law of conservation of energy: https://brainly.com/question/2264339

A.
Lane 7
B.
Lane 2
C.
Lane 3
D.
Lane 4
its for Environmental Science
Answer:
Lane 4
Explanation:
Based on the information that is provided, it seems that the gel electrophoresis analysis was conducted to determine the presence or absence of carp DNA in water samples from six different sites.
What happens in the process of gel electrophoresis ?In gel electrophoresis, DNA fragments are separated based on their size and charge by applying an electric field to a gel matrix. The negatively charged DNA fragments move towards the positively charged electrode, with smaller fragments moving faster and migrating farther down the gel than larger fragments.
In this particular gel, lane 7 is the negative control, which means that it should not show any bands of DNA fragments. Lane 8 is the positive control, which should show a band of DNA fragments of known size and sequence. The purpose of the positive control is to ensure that the gel electrophoresis is working properly and that the expected band is present.
If the bands formed in lanes 1, 3, 5, and 6 correspond to the band in the positive control lane (lane 8), then it suggests that carp DNA may be present in the samples taken from those four sites.
However, it is important to note that this inference is based on assumptions and limited information provided, and a more thorough analysis and interpretation of the gel electrophoresis results would be required to draw definitive conclusions about the presence or absence of carp DNA in the water samples from those sites.

Can a fossil be created in a few weeks? How long do you think it
takes a dinosaur fossil to form?
Answer:
Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years. But, that is just an arbitrary line in the sand – it means very little in terms of the fossilisation process.
Explanation:
Fossils are a record of organisms that lived in the past. are two main categories of fossils: body fossils and ichnofossils. Body fossils are the result of preservation of parts or the entire body of a plant, animal, or microorganism. These are the fossils that people are most familiar with, consisting of skeletons, teeth, shells, carapaces, organisms in amber, petrified wood, plant material, pollen, etc. Ichnofossils (also called trace fossils) are evidence of an organism’s activity. Common ichnofossils are animal footprints and trackways, burrows, traces of plant roots, coprolites (fossil feces), and borings in rocks, bones, wood, shells, or other substrates. The study of fossils provides information about ancient biological communities, and the physiology, behavior, and ecology of organisms.
In conclusion, fossilization at least at the present time, is thought to be a very unlikely process and it is believed that only a very small fraction of organisms that lived in the past became fossils. The majority of these fossils were hard skeletal parts or wood. To become fossilized, organisms must be rapidly buried, preferably in a fine sediment with geochemical conditions that favor the exchange of minerals between the sediment and organic components of the organism, and that exchange of minerals is possible because of dissolved minerals in flowing water. If those conditions occur, fossilization must necessarily be a rapid process of a few hours to a few months if it is to occur before decay destroys any record of the organism. Fossilization does not take thousands or millions of years, but is most likely to occur in catastrophic conditions such as would have existed during the Genesis Flood.

The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?
Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

3. Every species of fig has its own species of fig wasp to pollinate its flowers. Without the fig wasp, there would be no fig seeds. Without the fig, the wasp could lay no eggs. What is the relationship between these two organisms?
Answer:
obligate mutualism
Explanation:
A type of mutualism in which the species involved are in close proximity and interdependent with one another in a way that one cannot survive without the other.
The relationship between the fig wasp and the fig tree as described in the illustration would be symbiosis.
A symbiotic relationship is a form of mutualistic relationship between two organisms in which both of them benefit.
The fig wasp benefits the fig tree by helping with the pollination of their flowers. Without pollination, fertilization and seed production become impossible.
The fig tree, in return, benefits the fig wasp by providing a conducive environment for egg-laying. Without this environment, the fig wasp cannot lay eggs and the population of fig wasp will dwindle.

A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
pH decreases;
The gradient becomes sufficient.
H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.
Explanation:
A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease
At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.
H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.
