A train travels 67 km, north along a straight track in 39 minutes. What is the train's average
velocity in kilometers per minutes?
A. 28Km/mins
B. 1.72Km/mins
C. 0.582Km/mins
D. 106 Km/mins

Answers

Answer:

B. 1.72Km/mins

Explanation:

The topic is Mathematics, not Biology but okay!

All you have to do is 67/39 which equals 1.72km/mins.

This is because you have to work out the average speed in kilometres per minute. 39/39 = 1 minute

Can anyone help me write hydroelectric essay
INTRODUCTION:

CONCLUSION:
Please I really have bad life

Answers

Answer:

A competitive firm’s marginal revenue always equals its average revenue and price. This is because the price remains constant over varying levels of output. In a monopoly, because the price changes as the quantity sold changes, marginal revenue diminishes with each additional unit and will always be equal to or less than average revenue. A conclusion is the last paragraph of your essay, or, if you’re writing a really long essay, you might need 2 or 3 paragraphs to conclude. A conclusion typically does one of two things—or, of course, it can do both: Summarizes the argument. Some instructors expect you not to say anything new in your Hydro-power is the energy harnessed from running water-streams, rivers or any other artificial or natural water flow. It is one of the oldest method of energy production. Even in the medieval period, people used to derive energy from water wheels. The contribution of hydel power in the world en­ergy production scenario is immense and ever-increasing.

Hydro-electricity now contributes nearly 7% of global electricity production when only 15.3 percent of the global exploitable hydro-electric potential is being used. Ever increasing awareness of ecology and social costs of hydro-plant construction failed to debar the increas­ing use of hydro-electricity.

how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.

Answers

Answer:

No cells are produced.

Explanation:

If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.

pls help!!! osmosis help needed!!

Answers

Answer:

1. 10% 2. 90% 3. 80% 2. Yes 3. Into 3. Swell 6. Hypotonic

Explanation:

1. Given the image, it shows there is 10% glucose outside the cell.

2. Because there is 10% glucose outside the cell, you can automatically conclude that there is 90% of water outside. (You want it to equal to 100%. So, 10 + 90 = 100)

3. Given 20% glucose inside the cell based on the image, you can conclude that there is 80% water inside the cell.

2. Yes, osmosis will occur. Osmosis is the movement of water from a higher concentration to a lower concentration. In this case, there is more water outside the cell than in. So, yes, osmosis will occur.

3. The water will move into the cell (There's less water inside, and more outside, so of course, the water will move in).

3. The cell will swell, since water is getting moved in.

6. This is a hypotonic solution. Definition of a hypotonic solution: The concentration of solutes outside the cell is less than that of water. Hypotonic solutions always swell, as water moves into it.

A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from _________________ during meiosis.
a.) karyotyping
b.) nondisjunction
c.) crossing over
d.) synapsis

Answers

Answer:

b.) nondisjunction......

A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

What do you mean by Chromosomes?

Chromosomes may be defined as tiny, threadlike structures inside most cells of every organism, or living thing which carries the genetic information.

The presence of 3 X chromosomes indicates the condition of trisomy which arises as a result of non-disjunction.

When homologous chromosomes fail to separate at meiosis resulting in a germ cell containing 24 chromosomes rather than 23.

Therefore, a woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

If too many pandas are competing for bamboo (their food), what could happen?

Answers

Answer:

The correct answer would be - eventually, there will no be enough bamboo for all.

Explanation:

Competition for a single resource usually results in the scarce of the particular resource and eventually, there will be no resources in the end. In this case, it is given that there is too many Panda in a particular area competes for bamboo.

Due to this competition, there will be less bamboo initially, and eventually, there will be not enough bamboo for all the pandas. The correct answer will be - eventually, there will no be enough bamboo for all.

In dense forests, obtaining sunlight for plants can be tricky. Growing on the ground is not always effective for plants because there is not much sunlight hitting the ground. Orchids are epiphytes, or plants that grow on other plants. They grow on branches of trees high up in the canopy. They get more sunlight and have more access to pollinators up in the high branches. Orchids lay their roots on the bark of a tree and obtain nutrients and water from their surrounding environment.

In a short answer, identify and describe the type of symbiotic relationship between orchids and the forest trees, and explain the effect of this interaction on each species involved.

Answers

Explanation:

The symbiotic relationship between orchids and trees is called commensalism, which means the orchid and tree host depend on eachother to survive.. The orchid provides the tree with sunlight, (nutrients created by sun- exposure).

the tree provides a solid base for the orchid to climb up the tree, they are dependent on eachother for survival...

The type of symbiotic relationship between orchids and forest trees is commensalism.

What is commensalism?

Commensalism is a relationship in which one species benefits while the other is neither helped nor harmed. In this case, orchids benefit from the elevated position and access to sunlight provided by the trees, while the trees are neither helped nor harmed.

The effect of this interaction on orchids is that they are able to thrive in a challenging environment where they would not otherwise survive. The effect on forest trees is neutral, as the orchids do not harm or compete with them for resources. However, the presence of orchids on the tree bark may attract pollinators or other organisms, which could potentially benefit the trees indirectly.
