Why is the phloem in a leaf important to the roots of a plant?
A. It transports oxygen to the roots of the plant.
O B. It transports blastocysts to the roots of the plant.
O C. It transports water from the roots to the leaves.
OD. It transports carbohydrates to the roots.
Answers
Answer:
D. It transports carbohydrates to the roots.
Explanation:
Phloem is mainly used to transport nutrients from their region of production to the region that needs or stores the nutrient.
In photosynthesis, the method that plants make food, starch is produced. As the root hair cells needed energy to function, nutrients is needed so that it can respire and produce energy.
Therefore, when starch is produced, they will travel down the plants by the phloem to the roots where the nutrients is used.
brainlest please
As it delivers carbohydrates to the roots, the phloem in a leaf is vital to a plant's roots. So, the correct option is D.
What is Phloem?The plant tissue known as phloem is in charge of moving sugars, nutrients, and other organic substances from the leaves, where they are made by photosynthesis, to the other sections of the plant, such as the roots, flowers, and fruits.
Phloem has a bidirectional transport system that enables it to carry materials both across and down the plant. Sieve-tube elements and companion cells, which make up phloem tissue, are specialised cells.
A vascular tissue called phloem is in charge of moving sugars (carbohydrates) from the leaves to the roots and other sections of the plant. The plant may transfer the byproducts of photosynthesis through its whole system thanks to a process called as translocation.
Therefore, the correct option is D.

MIGHT GIVE BRAINLIEST Compare a paramecium with a giraffe. How are their cells alike? How are they different? Write
your answer in complete sentences. be original
Answers
Answer:
A paramecium is similar to a giraffe in one defining way. Both a giraffe and paramecium have eukaryotic cells. One way in which the two are different is that the paramecium feeds on decaying organisms, whilst a giraffe eats leaves. Another is that paramecium primarily live in fresh water, while a giraffe dwells on land.
A paramecium and a giraffe are two very different organisms. A paramecium is a single-celled organism, while a giraffe is a large, multicellular mammal. Despite their many differences, both a paramecium and a giraffe have cells. However, the cells of a paramecium and a giraffe are quite different from each other in terms of size, shape, and function.
One of the most significant differences between the cells of a paramecium and a giraffe is their size. The cells of a paramecium are very small, measuring only a few micrometers in diameter. In contrast, the cells of a giraffe are much larger and more varied in size, depending on their function within the body. For example, giraffe nerve cells are much larger than giraffe red blood cells.
Another important difference between the cells of a paramecium and a giraffe is their shape. The cells of a paramecium are typically elongated and oval-shaped, with a pointed end at one end and a rounded end at the other. In contrast, the cells of a giraffe are much more varied in shape, depending on their location and function within the body. For example, giraffe muscle cells are long and cylindrical, while giraffe nerve cells are elongated and have many branching extensions.
Despite their many differences, the cells of a paramecium and a giraffe do have some similarities. For example, both types of cells have a cell membrane that surrounds the cell and controls the movement of materials in and out of the cell. Both types of cells also have a cytoskeleton, which provides support and structure to the cell. Additionally, both types of cells have a nucleus, which contains the cell's genetic material.
Overall, while the cells of a paramecium and a giraffe have some similarities, they are also very different from each other in terms of size, shape, and function. The small, simple cells of a paramecium are adapted for life in a single-celled organism, while the larger, more complex cells of a giraffe are adapted for life in a multicellular mammal.

The type of asexual reproduction would be seen in a kitchen Binary Fission and budding. In a garden, vegetative propagation, fragmentation, spore formation, and regeneration.
What is Asexual reproduction?Asexual reproduction may be characterized as a mode of reproduction that does not involve the fusion of gametes or a change in the number of chromosomes. In this mode of reproduction, a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are clones of their parents.
The types of asexual reproduction that can be observed in everyday "real life" are as follows:
Binary fission: Single parent cell doubles its DNA, then divides into two cells.Budding: Small growth on the surface of the parent breaks off, resulting in the formation of two individuals.Fragmentation: Organisms break into two or more fragments that develop into a new individual.Regeneration: The natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.Vegetative propagation: It is an asexual method of plant reproduction that occurs in its leaves, roots, and stem.To learn more about Asexual reproduction, refer to the link:

it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Thorium-232 14.0 billion years
Rubidium-87 48.8 billion years
Potassium-40 1.25 billion years
Samarium-147 106 billion years
Earth is approximately 4.5 billion years old. Given this information and the data in the table, which of the following isotopes could today contain less than 50 percent of its parent isotope?
Rubidium-87
Thorium-232
Uranium-235
Uranium-238
Answers
Answer:
The amount of substance present in a certain sample can be calculated through the equation,
A(t) = A(o)(0.5)^(t/h)
where At is the amount now, Ao is the original amount, t is the number of years and h is the half-life.
For a substance to at most 50% of the original amount, we get the half-life value.
At/Ao = 0.5 = 0.5^(4.5/h)
h = 4.5 billion.
ok the answers are simple:
Parent Isotope Currently Accepted Half-Life Values: is the first one uranium-238 4.5 billion years

What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.

The p53 protein is a transcription factor that regulates a cell's progression through the cell cycle after DNA is damaged by ultraviolet ( UV ) radiation. The p53 pathway is shown in Figure 1.
Please answer this question! I will give brainliest!
Please note: p53 regulating image is for the entire problem, whereas part C image is only for part C.
(a) A skin cell completes one round of the cell cycle. Describe the products.
(b) Based on Figure 1, explain how p53 regulates the cell cycle in the presence of damaged DNA .
(c) Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
(d) Based on Figure 1, explain how a mutation to p53 may lead to an increased risk of cancer.
Answers
Answer:
(a) Since skin cells undergo the process of mitosis, the product of one cell cycle is 2 identical daughter cells.
(b) The levels of p53 protein in the cell will rise in response to DNA damage. This will stop the cycle at one point to give time to the repair machinery to regain stability. As can be seen in the figure, CDK inhibitors have been produced which are responsible for halting the cell cycle.
(c) The S phase (synthesis phase) is when replication of damaged DNA would occur.
(d) p53 responds in one of 3 ways to an event of DNA damage: arresting the cell-cycle, apoptosis (programmed cell death), or repairing the DNA. If there has been a mutation in p53, neither of the three way would take place to prevent more copies of damaged DNA being made. A mutated p53 protein would no longer be able to suppress tumors.
Hope that answers the question, have a great day!
The cell cycle is the process in which a cell undergoes four phases of division to give rise to daughter cells.
(a) The skin cell is a type of somatic cell, which undergoes mitotic division. The products of the cell cycle will be two identical daughter cells.
(b) p53 is a transcription factor, which will halt the replication if any error occurs. CDK inhibitors are produced in the cycle, which regains stability and activates the repair mechanism.
(c) The synthesis phase or S phase of the cell cycle is the site where replication of the DNA occurs. It takes place after the G1 phase.
(d) p53 transcription factor can arrest the cell cycle, cause apoptosis, and repair the cell damage. The mutation in the p53 gene can work in any fashion to prevent more damaged copies of the DNA. The mutation in p53 will lead to tumors.
