Explanation:
The palisade mesophyll and the spongy mesophyll are the parenchyma cells present in the middle portion of the leaf which performs a specific function.
The palisade mesophyll is present in the upper portion of the leaf and contains chlorophyll. The chlorophyll is involved in the process of photosynthesis therefore palisade layer perform photosynthesis.
The spongy mesophyll is arranged in the lower portion of the leaf in a loosely packed structure. The spongy mesophyll allows the circulation or flow of the carbon dioxide and oxygen in the leaf.
Since the stomata are present in a higher amount on the lower side of the leaf, therefore, gas exchange takes place through the lower portion and therefore the spongy parenchyma is present on the lower portion.
If the spongy parenchyma is present on the upper side and the palisade on the lower side then the gaseous exchange will be difficult and the photosynthesis will not be performed.
Palisade mesophyll and spongy mesophyll are parenchymal cells located in the central part of the leaf and perform specific functions.
Palisade mesophyll is located at the top of the leaf and contains chlorophyll. Since chlorophyll is involved in the process of photosynthesis, the Parisaise layer performs photosynthesis.
The spongy mesophyll is placed in a loosely packed structure at the bottom of the leaf. Sponge-like mesophyll allows the circulation or flow of carbon dioxide and oxygen in the leaves. Due to a large number of stomata on the underside of the leaves, gas exchange takes place from the bottom and there is spongy parenchyma at the bottom.
If the spongy substance is on the top and the fence is on the bottom, gas exchange will be difficult and photosynthesis will be difficult.
What is the function of a palisade mesophyll?The mesophyll layer is the walls where most photosynthesis occurs in the leaves. Palisade cells contain many chloroplasts that aid in this photosynthesis. Palisade cells are densely packed to maximize light absorption.
Hence concluded that if the palisade Mesophyll were below the spongy Mesophyll it will cause difficulty in photosynthesis.

Which does not affect the rate of mutation in a molecular clock?
- type of mutation
- the protein affected
- the time of divergence
- location of gene in genome
- none of the above
Answer:
location of gene in genome
Explanation:
The protein affected by a mutation does not impact the rate of mutation in a molecular clock. This rate is instead influenced by the type of mutation, time of divergence, and gene location in the genome.
Explanation:The factors that can affect the rate of mutation in a molecular clock include the type of mutation, time of divergence, and the location of the gene in the genome. However, the protein affected by the mutation does not directly impact the rate of mutation in a molecular clock. Three types of mutations include: substitution, insertion or deletion, and nonsense mutations, which could stop the replication or reading of a DNA strand, possibly leading to functional or non-functional proteins.
Mutations such as trinucleotide repeat expansions, insertions, deletions, and translocations can have significant effects on the protein produced. Similarly, missense and nonsense mutations can have varying impacts, depending on the specific changes made to the amino acid sequence of the protein.

(PICTURE INCLUDED)
Part C
Explain how gravity plays a role in the parts of the water cycle shown in this model.
Part D
Explain how water changes state in your model.
Answer:
Answer directly form edmentum
Explanation:
The water cycle in the given landscape includes evaporation, condensation, transpiration, groundwater, surface runoff, and precipitation. Gravity has a significant role in driving water downward during precipitation, thereby creating surface runoff and groundwater. Water changes states by moving from a liquid to a gas and back to a liquid.
Explanation:The water cycle in the given landscape operates in the following manner:
Evaporation: Water from the hydrosphere (H), such as the lake in the landscape, gains energy from the sun and transforms into gas, rising into the atmosphere (A).Condensation: As the water vapor rises and cools in the atmosphere (A), it transforms back into liquid, forming clouds.Transpiration: Plants in the biosphere (B) also release water into the atmosphere (A) in the form of water vapor. Groundwater: Some of the precipitation percolates into the ground, replenishing the geosphere (G) as groundwater.Surface runoff: Some of the water from the precipitation flows on the surface of the geosphere (G), creating surface runoff which eventually returns to the hydrosphere (H), such as the lake.Precipitation: When the cloud becomes heavy, the water falls back to the ground as precipitation.Gravity plays a key role in the water cycle by pulling down precipitation from the atmosphere to the ground. This helps in the creation of surface runoff and groundwater. The water changes states in this model by moving from a liquid (in the lake and rainfall) to a gas (during evaporation) and back to a liquid (during condensation).

What is the momentum of a 3 kg bowling ball moving at 3 ms?
1 kg. mis
3 kg. m/s
6 kg•mis
9kg. mis
Explanation:
We know that momentum is the product of mass and velocity so
Mass (m) = 3 kg
velocity (v) = 3 m/s
Now
Momentum
= m * v
= 3 * 3
= 9 kg. m/s
Hope you understood and hope it helps:)
The momentum of a 3 kg bowling ball moving at 3 m/s is 9 kg·m/s. Momentum is calculated by multiplying mass and velocity.
The momentum of an object is calculated by multiplying its mass (m) by its velocity (v).
In this case, you have a 3 kg bowling ball moving at 3 m/s, and you want to find its momentum (p).
The formula for momentum is:
Momentum (p) = mass (m) × velocity (v)
Now, you can plug in the values:
p = 3 kg × 3 m/s = 9 kg·m/s
So, the momentum of the 3 kg bowling ball moving at 3 m/s is 9 kg·m/s. This means that the bowling ball has a momentum of 9 kilogram-meters per second, which is a unit of measurement for momentum.

Each pot receives the same soil, the same amount of light, and the same amount of water. They add no fertilizer to Pot 1, 10g of fertilizer to Pot 2, 20g to Pot 3, and 50g to Pot 4. What are the fixed variables in this experiment?
POT 1
soil, light, water, type of plant
amount of fertilizer
Answer:
pot size, soil, amount of light, type of plant, amount of water.
Explanation:
The fixed variables would be the pot size, soil, amount of light, type of plant, and amount of water.
There are three variables in a research experiment:
fixed variablesindependent variablesdependent variablesThe fixed variables in an experiment are those variables whose values are kept constant throughout the course of the experiment. They are also referred to as controlled variables.
Independent variables are the actual variables being measured during an experiment.
The dependent variables are the variables being tested during an experiment.
The fixed variables are kept constant so as to be able to measure the effects that the independent variable will produce on the dependent variables during an experiment.
Hence, in this case, the fixed variables would be the pot size, soil, amount of light, type of plant, and amount of water; the independent variable would be amount of fertilizer and the dependent variable would be a growth-determining factor.
Answer:
D, type of soil would be your answer
Explanation:
The growth depends on the type of soil only since the other variables are the same for both pots.

Why is heaven closer than we think?
Answer:
The Church is a type of heaven
Explanation:
Church is much more than a good sermon, a few good songs, and good company. It is, or it is supposed to be, a cooperation between heaven and earth, a living synergy. What saddens me though is that we worship with verve, we pour everything into it, and yet too often the person at the end of the row remains a stranger to us. I’m not sure you can have one without the other. If we do not surrender ourselves completely, and not just to the familiar but to the unloved, fallen, and damaged life around us, our worship is empty, sapless, and misdirected.
