Answer:
Precipitation and temperature provide a suitable environment for the organisms and plants found in the coniferous biome. In this biome the temperature usually warm in summer that ranges from -40 degrees Celsius to 20 degrees Celsius over the year including warm summer and cold snowy winters. The rain or precipitation also affects biodiversity as the rainfall ranges from 30 to 89 cm over the year.
The high temperatures and rain make a warm, damp ecosystem that is suitable for organisms like insects and organism that depends on these insects and other organisms who requires these suitable warmer and climate in summer and cold winters also finds. The plants mostly have needles instead of leaves and coniferous that are able to found in these areas.

A because it consists of two nuclear divisons resulting in four nuclei that are usually turned into four new haploid daughter cells
Help me with this question pleaseeeeeeeeeeeee
I really need you to answer this.
Answer
A
Explanation:
Some animals don't eat a specific pray, and other hunt more than one specie, which means that they are all food for other organisms that are stronger than them.
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.
Errors that occur during meiosis are present in all cells of the body, whereas errors that occur during mitosis may occur in only a small number of cells.
Answer:
Due to difference in their presence in the body.
Explanation:
Errors that occur during meiosis are present in all cells of the body because meiosis cell division occurs in the sex cells of an organisms so that the errors are effects all the cells of that organism, while on the other hand, errors that occur during mitosis may occur in only a small number of cells because mitosis cell division occurs in the somatic cells so the errors are present in some body cells so we can conclude this errors in meiosis affect all cells whereas errors in mitosis affect less number of cells.

How are sedimentary rocks made. A. Magma or lava is cooled B. Materials are pressed together C. Chemical reactions change minerals. D. Earthquakes causes small pieces to fall
Answer:
B. Materials are pressed together
Explanation:
sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Sedimentary rocks are made up by the pressing down together the materials which are loosened through weathering. Thus, the correct option is B.
What are Sedimentary rocks?Sedimentary rocks are the type of rock which are formed by the accumulation or deposition of mineral particles or organic particles at the Earth's surface, followed by cementation of the particles.
Pieces of rock are loosened by weathering of particles, then these are transported to basin or depression where the sediment is trapped. If the sediment is buried deeply in the basin, it becomes compacted and cemented to form sedimentary rocks. Clastic sedimentary rocks may have particles of rocks ranging in size from microscopic clay to huge boulders.
Therefore, the correct option is B.

Different genotypes always produce different phenotypes. Explain, using an example, why this is NOT true.
Answer:
Different genotypes don't always produce different phenotypes because though AA & Aa are different genotypes, they are both dominant, therefore having the same phenotype.
Explanation:
Genotype:

Phenotype:
dominant dominant recessive
(same phenotype) (different phenotype)
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.
