Could someone please tell me if this is mold or not? I think it is but honestly I know nothing about that.

Answers

Answer:

It would be Penicillium or Aspergillus, if it is even mold. They are some of the fastest growing molds (usually within 24 to 48 hours) and require very little moisture for their colonies to develop. I haven't ever seen mold

When designing an experiment, you come up with the question: How does the amount you talk to a plant help it grow? Which would be the best hypothesis

Answers

Answer:

The correct answer is - "If you increase the amount you talk to plants, then they will grow taller"

Explanation:

A hypothesis is a proposed or assumed explanation for the natural system or problem. It forms on the pre-existed or known data or knowledge. A good hypothesis should have the ability to relate to dependent and independent variables.

In this case, the best hypothesis would be "If you increase the amount you talk to plants, then they will grow taller" as it relates to the dependent and independent variables that are the growth of the plant and talking to the plant respectively.

6 reasons why Meiosis and mitosis are different (PLEASE HELP)

Answers

Answer:

Reasons why they're different :

Explanation:

1. Mitosis is reserved for somatic cells while meiosis is reserved for sex cells (gametes).

2. Mitosis results in identical cells , while meiosis results in genetically distinct cells.

3. Mitosis undergoes one round of cell division while meiosis undergoes two rounds of divison.

4. Mitosis results in diploid daughter cells, while meiosis results in haploid daughter cells.

5. Unlike mitosis, meiosis differs in males and females.

6. Mitosis creates a human cell with 46 chromosomes, while meiosis creates a human cell with 23 chromosomes.

How would your body respond if your blood pH raised to 7.46?

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply

Will mark as brilliant answer

Answers

Answer:

Below :D

Explanation:

So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.

Lets think about what can cause a lack of increase?

A decrease can cause this.

Or a slow in the rate of increase.

Now lets look at our selectable answers and see if any of them would fall under these two things.

First up is fewer deaths.

Well, fewer deaths basically means less of a decrease in population.

This is the opposite of decreasing the populatin count, and would instead raise it.

Next we have a limit in food supply.

This would cause a organism to starve and die.

So this would cause a decrease in population count.

So B is one of the answers

Next up is competition with other species.

When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.

So this would also cause a large decrease in population count.

This makes C one of the answers

Next is increase in birth rates.

This would cause more organisms to be born of a species, basically increasing the population count.

This is the opposite of a decrease in  population.

Next we have competition for space.

This is very similar to answer C, and the outcompeted species dies out due to lack of space.

So E is one of the answers

Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.

However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.

So although major storms decrease populations, they dont actually limit them.

In the end:

B is correct

C is correct

E is correct

Hope this helps!

Describe TWO environmental consequences, other than those related to the loss of boreal forest habitat, that result from the extraction of bitumen or the transportation of synthetic oil to customers.

Answers

Answer: The greenhouse gas emissions from the extraction of bitumen and the use of large quantities of water.

Explanation:

Bitumen is a natural flammable organic matter formed from kerogen in the process of petroleum generation, which is soluble in carbon disulfide. Asphalt and mineral wax are examples of hydrocarbons which are part of bitumen. Conventional oil is extracted by wells while oil sands deposits are extracted using surface mining sectioning techniques, or are flowed to wells by in situ techniques that reduce bitumen viscosity by steam and/or solvents. So, unlike crude oil extracted in oil wells, bitumen requires an open-pit mining operation, in which large tracts are washed with a mixture of water and chemicals to separate the bitumen from a mixture of sand and clay.

Two consequences of this practice are:

The greenhouse gas emissions from the extraction of bitumen are larger than the extraction of conventional oil. The emissions produced contribute  to enhance the greenhouse effect and cause global warming. The greenhouse effect occurs when certain gases retain part of the energy emitted by the earth's soil when heated by the sun's radiation. This phenomenon occurs naturally, and thanks to it, the average temperature of the Earth is about 14º C (57.2 °F). The problem occurs when these greenhouse gases increase in the atmosphere and the amount of energy that is not released into space also increases and, with it, the Earth's temperature. The extraction of bitumen from oil sands requires the use of large quantities of water, and even though water used here can be recycled, only a small amounts is returned to the natural cycle. Also, spills from the transportation of the oil could damage soils and waterways, increasing water pollution. This toxic water  could get into surface.

Answer: Newton's first law of motion,

Explanation: Inertia is the tendency of an object to resist a change it its motion. Describe how inertia affects motion. If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.

7:

Answer: ​The second law

Explanation: ​The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).

8.

Answer: Newton's Second Law

Explanation: The second law of motion explains the relationship between force, mass, and acceleration. The law states that the acceleration of an object depends on the mass of the object and the amount of force applied. Newton's second law of motion is also called the law of force and acceleration.
