The cellular mechanism that determines the independent assortment of maternal and paternal chromosomes is: Please choose the correct answer from the following choices, and then select the submit answer button. determined by their dominant or recessive inheritance pattern. separation of sister chromatids at anaphase II of meiosis. separation of sister chromatids at anaphase I of meiosis. separation of homologous pairs at anaphase II of meiosis. separation of homologous pairs at anaphase I of meiosis.
Answer:
separation of homologous pairs at anaphase I of meiosis.
Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend or influence the allele of another gene in the same gamete. This random distribution can only be applied to independent genes. These genes segregate independently after crossing over because they are located far away from each other.
When cell division is going on by meiosis, it involves the random and independent segregation of the alleles. During anaphase I (meiosis), the pairs of homologous chromosomes separate independently of each other. Each integrant of the homologous pair migrates to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. The process is as follows.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. During anaphase I, each of the homologous chromosomes migrate to the corresponding pole. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.

why are manure better than fertilizers
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

Light travels through the eye by entering through the protective layer called the cornea (17). It then moves through the opening of the pupil which is surrounded by the iris (18), which is a muscle. It will then go through the transparent structure behind the pupil known as the ______________(19) that changes shape to help focus images on the retina in a process known as ________________ (20) The retina contains the photoreceptors known as the _________________(21) and ________________(22). It is there that the actual process of transduction occurs when the photoreceptors excite the ________________(23) cells which in turn send the message on to the _______________(24) cells whose axons make up the optic nerve. The information will then travel to the ____________________(25), which is the sensory switchboard within the brain and end up in the ____________________ (26) lobes where the information is processed specifically within the primary ____________________cortex (27).
Answer:
The correct answer is - 17) Cornea , 18) Iris , 19) Lens, 20) Accommodation , 21) Rods, 22) Cones, 23) Bipolar, 24) Ganglion , 25) Optic Nerve, 26) Occipital, 27) Visual.
Explanation:
The protective layer called the cornea that allows light to enter travel through it to the eyes. Light moves through the pupil surrounded by the muscle called the iris and travels through the lens, a transparent structure that changes its shape on the basis of the intensity of light to help focus images on the retina during the accomadation process. Photoreceptors that are present in the retina are called cones and rods.
The process of transduction takes place when these photoreceptors excite bipolar cells to send signals or messages to the ganglion cells that have axons that make the optic nerves, the sensory switchboard within the brain, and get the messages sent by the photoreceptors. These optic nerves end in occipital lobes where all the signals and messages are processed specifically within the region called the primary visual cortex.

2. What is the change (mutation) in DNA?
Answer:
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences.
Explanation:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations. Mutations can be introduced due to mistakes made during DNA replication or due to exposure to mutagens, which are chemical and environmental agents that can introduce mutations in the DNA sequence, such as ultraviolet light. Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.

Which of the following best describes the matter present in an ecosystem?
A.
New matter is continuously generated by an ecosystem in a process known as photosynthesis.
B.
The waste materials generated by one organism are often reused by other organisms.
C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.
