Answer:
D. Water
Explanation:
Biotic factors are all living things, and they are derived from organisms. These include: fungi, plants, bacteria, archaea, protists, animals.
Abiotic factors are all nonliving things, and they are not derived from organisms. These include: air, soil, light, water, minerals.
In this case, grass, trees, and algae are all living things since they are derived from organisms.
On the other hand, water is not a living thing since it is not derived from organisms.

DNA polymerase is an enzyme required in DNA replication. Its role is to synthesize DNA, adding individual nucleotides to each strand of newly synthesized DNA with the help of other enzymes such as primase and ligase. There are several families of DNA polymerase in both prokaryotes and eukaryotes, but through different species, portions of DNA polymerase are highly conserved. What do you think is the evolutionary significance of DNA polymerase? What do you think would happen if there was a genetic mutation on the genes encoding for DNA polymerase?
A sample answer would look like this: The DNA polymerase has evolutionary significance because it is required for DNA to be transmitted across generations. A genetic mutation in a gene encoding for DNA polymerase could lead to significant flaws in DNA replication, which could lead to major flaws in the DNA replicated for cell division. This could lead to large-scale errors and result in the death of the organism.
Answer:
Abstract. DNA polymerase I (pol I) processes RNA primers during lagging-strand synthesis and fills small gaps during DNA repair reactions. However, it is unclear how pol I and pol III work together during replication and repair or how extensive pol I processing of Okazaki fragments is in vivo

1. What kind of plant life dominates the coniferous forest biome?
A. deciduous trees
B. grasses
C. small shrubs
D. cone-bearing trees
Answer:
Small Shrubs
Explanation:
They Give off energy that makes them dominate the coniferous forest biome
The dominant plant life in the coniferous forest biome are cone-bearing trees, also known as conifers.
What is a coniferous forest biome?Coniferous forests are found in areas with cool, moist climates, such as the taiga regions of North America, Europe, and Asia. These forests are characterized by their dense stands of evergreen trees that are adapted to the long, cold winters and short growing seasons of their native habitats. The most common types of conifers in these forests include species of pine, spruce, and fir.
Conifers are easily recognizable by their distinctive needle-like leaves and reproductive structures, which are cones that contain the seeds. These adaptations allow conifers to conserve water, resist cold temperatures, and reproduce efficiently, making them well suited to the harsh conditions of the coniferous forest biome.
In contrast, deciduous trees, grasses, and small shrubs are more commonly found in other biomes, such as deciduous forests and grasslands.

Why is genetic diversity higher in big cities than in small towns?
Answer:
cities are more likely to have a population of people from other places while small town don't really have a Flux of population so it stays smaller
There is a genetic diversity higher in the big cities than in small towns because of the diversity of population that is present in it. The diversity brings out the different type of population in them.
What are the various factors that determine the population as well ?These are the availability of resources with the type of temperature and the environment that are determined in order to see the type of population present in it.
Genetic diversity is just influenced by the population size along with the with smaller populations that are having an increased probability of the inbreeding with the genetic drift and potential fixation of the deleterious types of alleles which just decreases the genetic diversity along with the adaptive potential.
Higher population of the genetic diversity that is in abundant species that is likely happening due to the combination of the demographic factors that are including the larger types of the local population that are in sizes with the faster generation times along with the high rates of the gene flow with the other type of populations.

how sexual reproduction plays its role in avoiding genetic monotomy
Answer:
Abstract
The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.

Answer:
16. Control group: Subject A
17. Independent (manipulated) variable: Type of powder
18. Dependent variable: Itching time
19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.
Explanation:
Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In this case, the experimental group is subject B.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used. The data does support the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).Which best describes how an enzyme affects the rate of a chemical reaction? Group of answer choices It changes the products created in the reaction. It increases the temperature of the reaction. It causes the reaction to proceed in an unfavorable direction. It lowers the activation energy of the reaction.
Answer:
It increases the temperature of the reaction.
Explanation:
Enzymes increase the speed of the chemical reaction. The reaction usually gets faster when the temperature is high. As a result, I think that this is the best choice of all.
When you exercise or sunbathe, you sweat. that sweat eventually evaporates. Why does this occur
Answer:
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.
Answer:
D. The biosphere change the lithosphere

Explain why the passenger pigeon,which was once the most abundant bird in north America,disappeared completely.
Answer with Explanation:
The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.

What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.
