Explanation:
Zeke is trying to plant a garden but he does not have much space. Zeke decides to trim the ends of the roots of the plants he is putting in his garden. After a week, Zeke notices that his plants did not grow at all. Explain why this happened.
Answer:
Zeke has cut the meristematic cells at the root tip, hence, the root will not elongate to get nutrients and water needed for plant growth.
Please find more explanation below
Explanation:
The root tips of a plant contain cells that actively divide, hence, causing growth or elongation of the roots. This allows the root to grow or penetrate into the soil in search of nutrients and water needed for the plants growth.
According to this question, Zeke decided to trim the ends of the roots of certain plants he is putting in his garden due to lack of space. However, he later discovered that these plants did not grow at all. This is because Zeek has cut off the root tip that contains the MERISTEMATIC CELLS responsible for the elongation of the roots into the soil. Hence, the roots are unable to absorb water and nutrients for the plant, preventing the overall growth of the plant.

what is photosynthesis
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. Here, we describe the general principles of photosynthesis and highlight how scientists are studying this natural process to help develop clean fuels and sources of renewable energy.
Types of photosynthesis:There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced along with carbohydrates.
Explanation:
photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
What is the longest phase of the cell cycle and why?
Answer:
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.

Which recent discovery led to a new understanding of how genetic mutations increase the risk of cancer? double helix structure of DNA BRCA1 and BRCA2 genes nucleic acid monomers formation of tumor suppressor proteins
Answer:
BRCA1 and BRCA2 genes
Explanation:
The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.
(B.) BRCA1 and BRCA2 genes

Answer:
The dog breeder to check for all the details that meets her requirement of dogs.
Explanation:
A dog breeding is the practice of mating dogs. In the context, it is given that a dog breeder wants to purchase a male dog of three year old for her business and she founds an advertisement on the net about a purebred males that costs $700. Now before buying this purebred male dog, the dog breeder should first of all check whether the seller who is selling online is a licence breeder or not.
The dog breeder should also check whether the dog is a purebred or not and should also find out the actual age of the dog. The health of the dog should be checked by an professional vet before buying the dog.
The selling of dogs, either a hybrid or a purebred costs differently. An individual should check the license and health of the dogs before purchasing.
In the given example, the dog breeder is trying to purchase a three-year male dog. She saw an advertisement that the male dog is available at the rate of dollars 700.
Before purchasing the dog, the breeder should check:
the authenticity of the advertisementrespective seller details and valid contact information the genotype of the dog as claimed purebred, and the health of the dog from a professional veterinarian.
Thus, the breeder should check all the authenticity of the dog and its health.

Answer:
differentiated; on; off
Explanation:
As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of cell, these cells will become differentiated Or This means they will turn Genes on for the type of cell they are becoming, and turn Genes off for the type of cell they won't be.
Stem cells become specialized cells through the process of differentiation. The stem cells all have identical DNA in them. They become specialized for a particular function (s) through the process of differentiation. During this process, some specific genes are either turned on or off. Cells in which the same genes are expressed become specialized for similar functions and can then come together to form a tissue.

What was the laws of heredity
Answer:
Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.
Explanation:The genetic experiments Mendel did with pea plants took him eight years (1856-1863) and he published his results in 1865. During this time, Mendel grew over 10,000 pea plants, keeping track of progeny number and type. Mendel's work and his Laws of Inheritance were not appreciated in his time. It wasn't until 1900, after the rediscovery of his Laws, that his experimental results were understood.
