c: allows some light to pass through
Explanation:
makes the most sense
Answer: A
Explanation: Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object.

why is prophase the longest phase of mitosis
Answers
Answer:
During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.
Answer:
During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condense into discrete chromosomes. The nucleolus also disappears during the early prophase. It's the most common/longest phase because of how long it takes to separate the chromatin, connect spindles, and prep for the rest. The cell essentially spends most of it doubling up on your DNA and prepping.

Describe how ions, water and sugar are obtained and
transported through plants.
6 mark
Answers
Answer:
Water and ions are obtained from soil and glucose is obtained from leaves.
Explanation:
Water and ions are absorbed by the plant through roots from the soil whereas glucose is produced in the leaves during the process of photosynthesis. Vascular bundles such as xylem and phloem transported water, ions and glucose within the body. Xylem moves water from roots to the upper water of plants such as leaves, stem etc whereas phloem transported glucose from leaves to other parts of plant.

Explanation:
Air tends to flow faster over ______ formations.
a. sheltered
b. medium-sized
c. shorter
d. taller
Answers
Answer:
d. taller
Explanation:
The air tends to flow faster over taller formations. Therefore option D is correct.
When air encounters different formations or obstacles, it can affect the speed and behavior of the airflow.
Taller formations, such as tall buildings, mountains, or cliffs, can create an obstruction in the airflow. When air encounters a taller formation, it is forced to flow up and over the obstacle.
As a result, the airflow can accelerate on the windward side of the formation and create faster wind speeds. This phenomenon is known as an acceleration zone or an area of increased wind speed.
Therefore, the correct option is d. taller formations. Taller formations can cause the air to flow faster due to the presence of acceleration zones or areas where the airflow is forced to speed up as it interacts with the obstacle.

Explanation:
Describe how DNA and RNA direct cell differentiation. Give an example of how environmental factors may influence cell differentiation.
Answers
Answer:
1- DNA: a specific DNA sequence encodes a transcription factor which activates the expression of target genes involved in cell differentiation
2- RNA: short non-coding RNAs may bind to enhancer regions and thus activate the expression of target genes involved in cell differentiation
3- Environmental factor: temperature may control the expression of genes involved in cell differentiation pathways
Explanation:
The deoxyribonucleic acid (DNA) contains the genetic material required to encode proteins. Some of these proteins are transcription factors involved in the activation of diverse signaling pathways, including, for example, cell differentiation and proliferation. On the other hand, microRNAs (miRNAs) are short non-coding RNAs that have the ability not only to repress but also to activate transcription by binding enhancer sequences. The miRNA activation mechanism has recently been discovered. In consequence, some miRNAs may potentially activate the expression of target genes involved in cell differentiation (e.g., c-myc gene). Finally, environmental factors (e.g., nutrient availability, salinity, temperature, etc.) may also activate gene expression and thus control diverse pathways such as cell differentiation, cell proliferation and cell death (apoptosis).

The possible allele combinations from the gametes of an organism with the genotype of AaBb is AB, Ab, aB, and ab. The correct option is D.
What are alleles?Alleles are variations of the gene. The offspring contain genes or traits from both parents. The same trait is given by both parents, one become dominant and one become recessive.
A gamete is a haploid cell that fuses with another cell to produce offspring, This occurs during fertilization. The female gamete is called ova or egg, or male cells are sperms.
When the genotype that will be produced by the fusion of AaBb is AB, Ab, aB, and ab. The small letters denote the recessive gene and the capital letter denotes the dominant genes.
Thus, the correct option is D. AB, Ab, aB, and ab.

A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?
Answers
Answer:
Because they don't have fertilizer.
Explanation:
Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring.

Answer:
A) In order for organisms to grow.
Explanation:
Tell me if I am wrong. I hope this helps :)
Cell division in a cell takes place in the single-celled organisms to reproduce and pass along the genetic information of the cell. Thus, the correct option is B.
What is Cell division?Cell division is the process of division of cell through which a parent cell divides into two daughter cells with equal genetic content which are similar to the parent cell. Cell division generally occurs as a part of a larger cell cycle in which the cell grows in size and the cell replicates the chromosomal material before it is undergoing cell division.
In the unicellular organisms, cellular division is a significant process through which a unicellular organism undergoes development and result into the formation of a new organism with genetic material which is similar to the parent cell. In the multicellular organisms, process of cellular division helps in maintaining a balance between the genetic material such as the DNA and the RNA contents as well as the nuclear and cytoplasmic contents of the cell.
Therefore, the correct option is B.
