What are the five main functions of nematodes in soil?
Answer:
Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.
Explanation:
hope this helps :)
Answer:
Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.
Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.
Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.
Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.
Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

What is the water cycle?
A: the storing of water under on or above the earth’s surface
B: the removal of water under on or above the earth’s surface
C: the continuous movement of water under on or above the earth’s surface
D: the creating of water under on or above the earths surface
C. The continuous movement of water under, on, or above the earths surface.
Answer:
C
Explanation:
The water cycle is a cycle, meaning it happens over and over again. Water isn't stored, created, or removed, it is moved around and it goes through different processes. For example, some stages of the water cycle are evaporation, condensation, precipitation, infiltration and run off.
Therefore choice C: the continuous movement of water under on or above the earth’s surface, is correct.
Insulin is a hormone that travels through the blood and helps regulate blood sugar levels. Which best describes how insulin travels in the blood?
in the plasma
in the platelets
attached to the white blood cells
attached to the red blood cells
Answer:
A:in the plasma
Explanation:
Insulin regulates blood sugar levels and it travels in the plasma. Therefore option A is correct.
What is insulin?Insulin is a hormone that is released by β-cells of the pancreas. It controls the amount of glucose in our bodies. It converts glucose into glycogen and then this glycogen is stored in the liver, and whenever the glucose level reduces in the blood, then this stored glycogen is converted into glucose. It also helps in breaking fat and protein for energy.
Insulin is a very important hormone for the regulation of glucose in the blood. A deficiency of insulin occurs when the immune system attacks islets and it causes diabetes, in this disease blood sugar level increases
.
Insulin flows in the blood through plasma. Therefore, option A is correct.

What does it mean if you find a skeleton and all of the sutures on the skull are fused? Be specific by using ages in your explanation.
(Forensics)
Answer:
If the scull is fused the individual is not a baby
Explanation:
If a skull is found, one of the first things to do is classify by age. Careful observation will show that the skull may or may not be fused. Noteworthy observations could give the professional an idea of the individual's age.
In the womb when the bones of the skull are being formed thre are typically seven bones with gaps in between. This allows the infant to pass safely through the birth canal but giving way to squeezing and the contractions of the uterus. After the child is born there are still remaining gaps. These gaps allow the brain to grow and develop without pressure from the skull. This can often be observed by a soft spot on the top of the infant's head sometimes called a "mole"
Around two years of age, these bones begin to fuse and harden. Therefore if a skull is found with fused bones, the individual can be placed to be older than two years of age. Other determining factors such as teeth etc can narrow down the individual's age.
Which of these is found within all cells?

Determine whether each activity impacts land resources in a positive or negative way. Drag each term to the correct
category.
desertification
Positive Impacts
Negative impacts
reforestation
laws and regulation
habitat restoration
erosion
urbanization
deforestation
Answer:
desertification - negative impacts
Reforestation - positive impacts
laws and regulation - positive/negative impacts
habitat restoration - positive impacts
erosion - negative impacts
Urbanization - negative impacts
deforestation - negative impacts
Explanation:
Desertification is a process in which productive lands become a dry, unproductive one as a result of humans or natural activities such as drought, deforestation, etc. It impacts land resources negatively in that land generally becomes unproductive and unsupportive to other lives.
Reforestation is a process of artificially creating forest where one has been removed or where none existed before. It involves the planting of trees and leads to the creation of new land resources such as habitats, water sheds, etc.
Laws and regulations can impact land resources either positively or negatively depending on the type of laws. Laws that promote land conservation positively impact land resources while those that promote the wanton use of lands negative impact land resources.
Habitat restoration refers to activities geared towards restoring habitats of organisms that have been degraded by human or natural activities. Habitat restoration positively impacts land resources as natural processes are directly impacted positively.
Erosion involves the removal of topmost layer of soils by running water or wind. It negatively impacts land resources by rendering land unproductive impacting the protective nature of soil on other resources such as watershed, etc.
Urbanization refers to the process of actively developing an area vis a vis the construction of more buildings and other infrastructures to make a place more urban. Land resources are negatively impacted in the process as most often requires the conversion of lands to non-forested uses.
Deforestation is the removal of forest layers for non-forest uses. It negatively impacts land resources such as habitat removal, lower biological diversity, protection of water sheds etc.

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
1. The percentage of butterflies in the population that are homozygous dominant
2. The number of heterozygous butterflies if the population contained 4,216 individuals
Answer:
48% Heterozygous of the population, 12% Homozygous dominant size.
Explanation:
Given the characteristics of its population,
Brown (B) predominates over white (b) color.
Recessive phenotype frequency (Q)= 40%= 0.4
According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.
So then, P = 1-Q
P=1-0.4=0.6
Heterozygotic butterflies = 2PQ
So, 2PQ= 2x0.6x0.4=0.48
That is, 48 percent of people are heterozygous
Homozygous dominant individual frequency = 1-(40 + 48) = 12 i.e. 12%
Answer:
C. 0.48

in 1994, naturalists in Australia discovered a new genus and species of conifer, Wollemia nobilis, growing in a remote area not far from the city of Sydney. This was the first new conifer discovered since 1948. Wollemi pine (not really a pine) is in a family that had global distribution in the Crustaceous period. Scientists used a variety of different evidence to decide where this rare tree should be placed in the "Tree of Life." What evidence would be necessary to determine that this is in the phylum Coniferophyta?
Answer:
The following should be the characteristics exhibited by the plant to place it under the phylum Coniferophyta:
1. Only the male cones should possess the tendency to generate pollens.
2. The plant should have the stems, leaves, and roots in the form of vegetative organs.
3. Possess the tendency to generate pinecones.
4. The plant should possess leaves in the form of a needle that stays green throughout the annum.
5. The leaves of the plants should possess cuticle deposition.

Use the word bank below to complete the passage below describing mitosis and meiosis. All words will be used at least once and most words will be used more than once.A) diploidB) mitosisC) meiosisD) sister chromatidsE) haploidF) homologous chromosomes1) A male giant panda has 42 chromosomes in its skin cells. This represents the _________ chromosome number. As the animal's old skin cells die and slough off, cells nearby divide through _________ to produce more skin cells. 2) Germ cells within the animal's testicles undergo _________ to replicate themselves and _________ to produce sperm. 3) The cells produced by mitosis in this panda have a _________ chromosome number and are produced after _________ are pulled apart into separate daughter cells.4) The cells produced by meiosis I in this panda have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells. 5) The cells produced by meiosis II in this animal have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells.
Answer:
1. diploid ,Mitosis
2. mitosis, meiosis
3. diploid, sister chromatids
4. haploid, homologous chromosome
5. haploid, sister chromatids
Explanation:
1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.
2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.
3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.
4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.
5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.

Which of the following statements regarding selenium/selenoproteins is incorrect?
a. They are proven protection against colon cancer.
b. The amount of selenium in foods depends upon the soil where the plants were grown and animals grazed.
c. Selenium functions as an antioxidant.
d. Selenium plays an important role in the regulation of thyroid hormones.
Answer:
The correct answer is: A. They are proven protection against colon cancer.
Explanation:
Selenium is a mineral that can be incorporated into our bodies in small amounts when we consume certain foods, such as whole grain and dairy products. The amount of selenium in these products depends on the soil where the plants and animals were.
Selenium plays an important role as an antioxidant, which can lower the risk of developing several types of cancer. However, this doesn't mean that its consumption can prevent colon cancer, and the studies that had been done to prove its effectivity in these regards have been inconclusive.
Besides functioning as an antioxidant, selenium also is very important for the regulation of the thyroid hormones, which play an important part in metabolism.
The protein that contains selenocysteine amino acid remnants is called selenoproteins. They are found in the endoplasmic reticulum of the cells.
The incorrect statement is:
Option a. They are proven protection against colon cancer.
The statement can be explained as:
Selenium is a mineral that gets incorporated into our body through foods, dairy and whole grains. The amount of selenium depends on its amount and presence in the soil.Selenoproteins are good antioxidants that can lower the risks of cancers. But its consumption does not provide complete protection against cancers.It also regulates the thyroid hormone and plays a vital role in the regulation of metabolism.Thus, they have not proven medication for colon cancer.
