In one of the first steps in Prophase I of meiosis,
A) the cell divides into four daughter cells.
B) the chromatids separate and move to opposite ends of
the cell.
C) half of the chromosomes are made inactive.
D) homologous pairs of chromosomes form tetrads
Answer:
D) homologous pairs of chromosomes form tetrads
Explanation:
During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
Justine is ice-skating at the Lloyd center what is her final velocity if she accelerates at a rate of 2.0m/s for 3.5 seconds?
7 m/s
Explanation:
Acceleration,
Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.
Making v the subject then
v=at+u
Taking u as zero then
Substituting 3.5 for t, 2 as a then
v=3.5*2=7 m/s

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
GranulationRecrystallizationMetasomatismMassiveFoliationFoliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.
If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.
What is a foliation?Foliation on a rock means continuous multi layering on a metamorphic rock.
These layers can be thin as a sheet of paper.
Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.
Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

The growth of plants stop if its apical part is cut,why？
Answer:
On some kinds of plants, the meristem is arranged so that when the tip of a branch or stem - which contains the apical meristem, from which new growth is initiated - is cut off, new stems or branches are signaled to start growing from the side, an area called the cambium or lateral meristem. These kinds of plants don’t die if the tip is cut off - instead they grow new branches.
Explanation:
good luck
Answer:
The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down the stem towards the axillary bud... When the apical is removed bud I'd removed, the lowered IAA concentration allow the lateral buds to grow and produce new shoots, which compete to become the lead growth

Explain how Enzyme A acts as a catalyst in the reaction. Be sure to include energy and time in your answer.
Answer:
Enzyme A acts as a catalyst by lowering the activation energy the reaction needs in order to take place this would in turn lower the reaction time of the reaction lading to a faster reaction. when conditions around the enzyme change this may lead to the breaking of hydrogen bonds causing the active site to change in shape, this change would would lead to the substrate no longer being able to fit which would lower the rate of reaction.

A student crested a model to show the flow of energy in a terrestrial ecosystem.
Which of the following correctly describes the way energy enters and leaves the ecosystem?
A Energy enters the ecosystem as sunlight, which is used by plants to produce sugars Energy leaves the ecosystem as heat from plants, herbivores, carnivores, and decomposers
B Energy enters the ecosystem from decomposers and is used by plants to produce sugars Energy leaves the ecosystem during cellular respiration
C Energy enters the ecosystem when it is transferred from the herbivores to the plants. Energy leaves the ecosystem as heat from plants, herbivores, carnivores and decomposers
D Energy enters the ecosystem as sunlight, which is used by plants to produce sugars. Energy leaves the ecosystem as mineral nutrients
The flow of energy in the terrestrial ecosystem is initiated by the sun and its flows to plants and then animal life and finally reaches the decomposers. Thus the option A is correct.
What is an ecosystem?An ecosystem is an ecological unit and its function is to balance the flow of energy in the environment. The flow of energy is unidirectional and as energy flow in one direction, it cannot be destroyed completely as it changes its form.
The energy that is received from the sun is transferred to the green plants, they include this energy to animals that are producers to consumers that include primary consumers and secondary consumers to decomposers, and then this energy leaves the system.

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?
In decimal form this is 0.5 and it converts to 50%
===================================================
Explanation:
Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%
This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.

change?
Answer:
If in a particular lake, thousands of small fishes are added, then the number of the larger fishes will increase. The reason for this is because in general the larger fishes are feeding on the smaller fishes, thus with the introduction of the thousands of small fishes there will be an increase in their food source.
