The effect of the biogeochemical cycle is the recycling of elements in the
ecosystem.
The biogeochemical cycle consists of the following cycles
Water cycle
Oxygen cycle
Nitrogen cycle
Carbon cycle
These recycling takes place between the non living and living organisms.
Primary producers make use of these elements in the production of food for the consumers and failure to recycle these elements means the ecosystem
will be wiped out.

You are studying the bacteria in the water of a nearby pond. From a 100 mL sample, you use a 0.5 mL subsample to inoculate a plastic dish filled with a semi solid nutrient medium that fosters growth of coliform bacteria. After an appropriate incubation period, you count 100 bacterial colonies growing on the surface of the medium. What conclusion can you make about the coliform bacteria in the pond water
Answer:
There are 20,000 colony forming units of coliform per 100 mL of the pond water.
Explanation:
0.5 mL of the 100 mL sample was inoculated.
There were 100 colonies in the 0.5 mL of the sample.
Hence, the number of colonies that would be in the 100 mL can be calculated as:
100 colonies = 0.5 mL
x = 100 mL
x = 100 x 100/0.5
= 20,000 colonies
Hence, the conclusion that can be made is that there were 20,000 CFU (colony forming units) of coliform bacteria in a 100 mL sample of the pond water.

3) Which of the following statements about independent assortment and segregation is correct?
A) The law of independent assortment requires describing two or more genes relative to one
another
B) The law of segregation requires describing two or more genes relative to one another.
C) The law of independent assortment is accounted for by observations of prophase I.
D) The law of segregation is accounted for by anaphase of mitosis.
Answer:
im pretty sure c but not sure
Explanation:
The independent assortment is one that describes how different genes independently get separated from one another. This process takes place during the development of the reproductive cells.
During mitosis, the parts of the chromosome are divided into haploids. Thereby separating the assortment. The example of pea-shaped genes is a law of independent assortment and segregation.Hence the law of assortment needs describing two or more genes relatively to one another.Thus option A is correct.

Darwin and Wallace both observed greater species richness in the tropics than in Europe, but neither of them had a good explanation for why. One of the best-supported modern-day hypotheses to explain this pattern is that mutation rates are higher in the tropics than in temperate latitudes. Why would higher mutation rates lead to greater species richness
Answer:
Mutation shows the species energy relationships, tropics are more rich with energy as compared to the temperate europe.
Explanation:
The rate of species evolution is defined by the type of environment or the natural surroundings it lives in. Mutations Can affect organisms by making changes in their physical characteristics. Such can impact their DNA code and may even lead to death in many. The richness of species in the tropics is due to the more warmer and humid climates. They are suited to the development and germination of certain bacterias and have certain climatic phenomena.A scientist recently discovered a brand new organism.

Kingdom Animalia
Explanation:
Being a eukaryote will eliminate Kingdom Archaebacteria and Kingdom Eubacteria, since those are bacteria and prokaryotes. Being a heterotroph (break down complex organic structures for nutrition) will eliminate Kingdom Plantae, since plants are autotrophs (makes nutritional organic substances from inorganic substances-the process of photosynthesis). Therefore the answer is Kingdom Animalia

Scientists recently published a paper about an endangered population of Scarlet Bass (species A) in Lake Erie. The authors also published its entire mitochondrial DNA sequence on Genbank, an online system where scientists submit genomic data. Another group of scientists later published an article using molecular data to estimate gene flow among populations of the very abundant Grey Bass species (species B) in Lake Erie, and published mitochondrial data on Genbank as well. After you read the papers you realize that the ranges for species A and a few isolated populations of species B overlap; you look at the sequence data published online from both studies, and you realize they are very similar and differ only by a few nucleotide differences. 8. Do you think these are closely related species, or variants of the same species
Answer:
They are variants
Explanation:
The biological concept of species states that members of the same species can reproduce they have a genetic reservoir in common: many genetic variants.
Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.
Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.
Groups A and B can be considered variations of the same species. They not only overlap but also share most of the genetic sequences with only a few nucleotide differences.
These variations might be the previous step for sympatric speciation.

Answer choices-
A. Synapsis of homologous chromosomes
B. Chromosome segregation
C. Fertilization
D. Cytokinesis
Answer:
Answer is Option B
Explanation:
Chromosome segregation
maybe this might be ur answer
In the process of meiosis, chromosomal segregation explains the probability that a particular allele will be in a gamete. Thus, the correct option is B.
What is Chromosomal segregation?Meiosis is a type of cell division. It is called reductional division as it involves the reduction in the number of chromosomes by half. This type of division is found to occur in the gametes in case of sexual reproduction.
Chromosome segregation is the process which occurs during meiotic division in the eukaryotic cells by which two sister chromatids that are formed as a consequence of DNA replication, or paired homologous chromosomes, separate from each other and migrate to opposite poles of the nucleus of the dividing cell. This segregation process occurs during both mitosis and meiosis.
Therefore, the correct option is B.

When completing this exercise, it may be useful to refer back to Labs 10-12 for information about living primates. In 2009, a new fossil species, called Darwinius masillae, was identified in Germany, represented by a nearly complete skeleton nicknamed Ida (depicted on p. 387 of your lab manual). It lived around 47 mya. It had a small brain, short protruding snout, large eyes, and postorbital bar. Its diet probably included a lot of fruit and leaves. It did not have a dental comb. It had nails instead of claws and was probably an arboreal quadruped. Researchers disagree about whether the fossil is more similar to living haplorhines (tarsiers, monkeys, and apes) or more similar to strepsirhines (lemurs and lorises). The skeleton is about 23 inches (58 cm) long including the tail, and has a body length of about 9 inches (24 cm) without the tail. Describe at least two features that Darwinius shares with living haplorhines.
Answer:
short protruding snoutlarge eyesIt had nails instead of clawsAbsence of dental combLong tailExplanation:
Haplorhines and Ida share the following characteristics:
- Both of them have plane nails in their fingers instead of claws. Nails are useful while eating and grooming. They might be necessary for defense too.
- They have a short snout, which is the cause of a poorly specialized olfactive perception.
- Neither of them has the dental comb characteristic of strepsirrhines.
- Eyes are big, located in the frontal area of the skull, and facing front. Vision sense is very developed. They have binocular vision, which allows them to calculate distances.
- The long tail is shared by both groups. Used during motion, to equilibrate, to hold, or grab.

The cardiovascular system is composed of two circulatory paths: pulmonary circulation and systemic circulation.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the
A. left side of the heart where it is pumped to the lungs for oxygenation
B. lungs where blood picks up oxygen and returns to the left side of the heart
C. lungs where blood picks up oxygen and returns to the right side of the heart
D. lungs where the blood picks up oxygen and transports it to the tissues of the body
Answer:
B. lungs where blood picks up oxygen and returns to the left side of the heart.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The cardiovascular system comprises of two circulatory paths:
I. Pulmonary circulation.
II. Systemic circulation.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where blood picks up oxygen and returns to the left side of the heart.
The pulmonary circulation loop is mainly supported (powered) by the right atrium and right ventricle.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

Analyzing the following tree, prove the relationship between ray-finned fish and crocodiles using the characteristics given below. Include at least three (3) characteristics that the organisms DO NOT have in common and one characteristic that they DO have in common. Your paragraph should be at least four (4) sentences. Remember to answer in COMPLETE sentences and use proper grammar.
Answer:
The Ray- Finned Fish has a bony skeleton just like crocodiles. Crocodiles evolved more and adapted to their environment. Along the way Crocodiles grew to have four limbs, were born from an amniotic egg, and then their eggs also have shells, unlike the Ray-finned fish. Therefore the three characteristics they do NOT have in common are: Four Limbs, Amniotic Egg, and Eggs with Shells. The one trait they do have in common is Bony Skeletons. They also both have vertebrae.
