explain how the products of photosynthesis are stored leaves!​

Answers

Answer:

The products are stored in the form of starch because glucose is soluble

Explanation:

Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

Answer:

Explanation:

Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.

What is soil erosion?

The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.

Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.

Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.

Answers

Answer:

The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.

The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.

The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.

Explanation:

The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.

In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

Given the following phylogenetic tree, which evolutionary event occurred most recently?

A.) development of different forms of symmetry.

B.) development of tissues.

C.) each of these traits evolved at the same time.

D.) protostome and deuterostome development.

Answers

Answer:

Option-D

Explanation:

A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.

The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.

The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.

Thus, Option-D is the correct answer.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?

A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.

Answer:

B

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Complete the analogyfact : fiction ::unreal: delusiondisbelief: delusionreality: delusionfantasy: delusion Distributions of electric charges in a cell play a role in moving ions into and out of a cell. In this situation, the motion of the ion is affected by two forces: the electric force due to the non-uniform charge distribution in the cell membrane, and the resistive force (viscosity) due to colliding with the fluid molecules. In order to begin our analysis of this, let's consider a toy model in which the ion is moving in response to electric forces alone. Charges in a cell membrane are distributed along the opposite sides of the membrane approximately uniformly. This leads to an (on the average) constant electric field inside the membrane. A simple model that gives this kind of field is two large parallel plates close together. The field between the plates is approximately constant pointing from the negative to the parallel plate. This results in a charge feeling a constant force anywhere between the plates (sort of like flat-earth gravity turned sideways). Outside of the plates the electric fields from the two plates cancel and there is no force. 2. The electric field between the plates (inside the membrane) is about 107 N/C and the thickness of the membrane is about 7 nm.
