The Climate is a key atmospheric system that contributes in the distribution of biomes.
What is a biome?A place is categorized as a biome based on the species that call it home. Scientists can define a biome by defining the temperature range, soil type, amount of light, and water that are peculiar to a location and create niches for particular species.
The climate that we have in a given place is what determines the kind of biome that we would have in that area since there is an interchange between the living and the non living components on a regular basis in the biome.

Which of the following correctly describes the functions of the rough endoplasmic reticulum (RER) and Golgi apparatus, respectively?
Answers
Answer:
The rough endoplasmic reticulum (RER) is involved in the synthesis, folding, and modification of proteins, particularly those that are destined for secretion or for use in the cell membrane. It has ribosomes attached to its surface, which are responsible for protein synthesis.
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids into vesicles for transport to their final destinations, either within the cell or outside of it. It is also involved in the synthesis of certain carbohydrates. The Golgi apparatus receives vesicles from the endoplasmic reticulum and modifies their contents before sending them on to their final destination.

Do plants take in air with their roots?
Answers
Answer:
No
Explanation:
No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.
HOMOLOGOUS CHROMOSOMES SEPERATE FROM EACH OTHER WHAT STAGE
Answers
Answer:
Homologous chromosomes separate from each other during anaphase I of meiosis.
Explanation:
Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.
During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.
In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.
DNA originally contains two parent strands, each forming one side of the double helix.

The daughter DNA molecule consists of 2 newly formed strands
The daughter DNA molecule consists of 2 parent strands
The daughter DNA molecule consists of an uneven mix of old and new strands
Answers
DNA replication is semi-conservative because the original molecule separates into two different strands, and each of them works as a model for a new strand to grow. A) The daughter DNA molecule consists of 1 parent strand and 1 new strand.
Why is DNA replication a semi-conservative event?
DNI replication is semi-conservative because, after replication, each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.
The replication products are double-stranded DNA molecules, each carrying an original strand and a new one.

Explanation:
Create an argument using empirical evidence and scientific reasoning to defend one of the following sexual reproduction methods as the most effective: animals’ internal fertilization, animals’ external fertilization, flowering plants’ wind pollination, or flowering plants’ animal pollination.
Give at least two scientific reasons for why the method that you chose is most effective at creating genetic diversity. Part of your argument should refer to the structures involved. Your argument should also include examples of why at least two of the other methods are not as effective.
Answers
Answer:
I would argue that animal pollination of blooming plants is the most successful form of sexual reproduction for generating genetic variation.
According to science, animal pollination enables the transport of pollen from one flower to another, increasing the genetic variety of the population. This is so that there is a greater potential of genetic mixing because different animals may visit various blooms, dispersing pollen from various plants.
Another justification is that, in contrast to wind pollination, animal pollination frequently entails actively moving pollen from one flower to another, which may result in higher genetic variety. While wind-borne pollen frequently travels enormous distances, it also tends to be dispersed by plants that are close relatives. Animals who visit flowers and spread pollen, on the other hand, are more likely to visit a variety of plants, encouraging greater genetic mixing.
Animal pollination also transfers genetic material from one plant to another, rather than only within a single plant or a group of closely related plants, making it more effective in promoting genetic variety than both animal internal fertilisation and external fertilisation.
Due to its capacity to encourage the transfer of pollen from various plants and physically transport the pollen, which results in greater mixing of genetic material, animal pollination of flowering plants is, therefore, the most effective method of sexual reproduction in terms of generating genetic diversity.Hope it helps! : )What color is Chocolate Milk.

Is crick and Watson a type of genetic test
Answers
No, "Crick and Watson" is not a type of genetic test. Crick and Watson refer to James D. Watson and Francis Crick, who were scientists involved in the discovery of the structure of DNA. They proposed the double-helix structure of DNA in 1953, which provided the foundation for understanding genetic information and its role in heredity.
Genetic tests, on the other hand, are laboratory tests that analyze an individual's DNA or genes to provide information about their genetic makeup, potential genetic disorders, or predispositions to certain conditions.
These tests can be used for various purposes, such as diagnosing genetic disorders, predicting the risk of developing certain diseases, determining carrier status for genetic conditions, or providing ancestry and genealogical information.
While Crick and Watson made significant contributions to the field of genetics, they are not directly associated with genetic testing. Genetic tests are based on scientific advancements and technologies developed after their groundbreaking discovery of the DNA structure.

Look at the incomplete equation below. What does Ek represent?
Answers
In the given equation, Ek represents the kinetic energy of an object.
Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.
The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.
The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.
The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.
Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.
Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.

If a disease kills the beech trees in the forest, the chanterelle mushrooms will likely survive but reduce in population size.
Obligate associationsSince the mushrooms are found to only live in association with oak and beech trees, the relationship with the trees can be said to be obligatory.
Without the two trees in the forest, the mushroom will likely go extinct.

Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
